System and method for managing construction projects

Abstract

A system for managing construction projects includes a database, a component interface, a state interface, and a database interface. The component interface is operative to receive component identifiers identifying components of a construction project. The state interface is operative to receive state indicators, each state indicator indicating a particular state (e.g., ordered, in transit, installed, inspected, etc.) associated with one of the components. The database interface is operative to store the component identifiers and the associated state indicators in the database. A method of managing construction projects is also described. The method includes the steps of receiving a plurality of component identifiers from a user, associating an initial predefined state with each received identifier, storing the component identifiers and the associated initial states in a database, updating the states associated with the component identifiers in the data base, and retrieving the updated states from the database to determine the status of the construction project. Novel data structures, application program interfaces, and graphical user interfaces are also disclosed.

Description

BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] This invention relates generally to construction project management, and more particularly to a system and method for tracking the progress of construction projects.

[0004] 2. Description of the Background Art

[0005] Managing a large construction project is a complex undertaking. Typical tasks include, but are not limited to, project design, ordering materials and supplies, fabrication, transportation of fabricated components, installation, inspection/testing, employee management, monitoring the use of resources, and customer billing. To complicate matters further, many of these tasks are performed at a construction site that is some distance from the construction company's central office, making supervision of the project even more difficult.

[0006] Having current information regarding the status of a project is critical to proper management. For example, current status information is required for a manager to determine whether a project is on schedule and/or is staying within budgetary constraints. As another example, it is common for construction contracts to provide for a payment schedule that is tied to certain percentages of completion of the project. Thus, it is important for management to know (and to be able to demonstrate to a customer) the status of a project, because delays in collecting and compiling status data result in delays in receiving payment. Under current practices, the time required to collect and process status data can be weeks for complex projects.

[0007] Another problem encountered in the management of construction projects is that certain critical projects (e.g., food handling systems, pharmaceutical systems, etc.) require validation that the project has been constructed in accordance with certain standards. Such validation typically requires the compiling of inspection reports and of product and/or process certifications of installed components. It is not uncommon for the validation process to take up to six months after project completion.

[0008] It is also difficult to maintain a “paper trail” of the project for warranty, liability, and/or other purposes. For example, if an installed component fails, it will be necessary to retrieve any information (e.g., manufacturer, inspections, warranty information, repair/replacement information, etc.) relating to the failed component. Under current practices, locating such information is extraordinarily time consuming. First the component must be identified. Then the purchasing records must be searched to determine which vendor provided the component. If more than one vendor provides identical components, it may be impossible to determine and/or prove the source of the component. Even if the vendor can be determined, it still remains to search records to determine the vendor's and/or manufacture's responsibility. Indeed, the time and expense required to collect the information on the component may well exceed the cost of simply replacing it.

[0009] For several reasons, detailed data related to the status of a construction project is not typically collected. First, as explained above, construction sites are physically removed, making data collection more difficult. Another reason is that workers at the site (electricians, plumbers, welders, etc.) are tradesman skilled in their field, but not trained, equipped, or necessarily willing to collect detailed data at a construction site. Yet another reason might be that data on the status of a project will be of little value when the project is complete. For example, the most detailed data is of little value if it cannot be compiled and presented in a manner that provides useful information. Whatever the reason(s), detailed data regarding the status of construction projects is not currently collected.

[0010] What is needed, therefore, is a system and method for providing the current status of construction projects. What is also needed is a system and method for providing near real-time information regarding the status of construction projects. What is also needed is a system and method for providing current costs expended on a construction project. What is also needed is a system and method for organizing and providing certification, inspection, and other information related to components of a construction project. What is also needed is a system and method for easily collecting data at a construction site. What is also needed is a system and method for presenting construction project data in a useful manner.

SUMMARY

[0011] The present invention overcomes the problems associated with the prior art by providing a system and method for managing a construction projects that provides current information on the status of the projects. The invention facilitates the easy entry of data corresponding to the construction status (e.g., ordered, installed, inspected, etc.) of particular components of construction projects, and the provision of the data in a clear and concise manner to a project manager.

[0012] A system for managing construction projects includes a database, a component interface, a state interface, and a database interface. The component interface is operative to receive component identifiers identifying components of a construction project. The state interface is operative to receive state indicators, each state indicator indicating a particular state (e.g., ordered, in transit, installed, inspected, etc.) associated with one of the components. The database interface is operative to store the component identifiers and the associated state indicators in the database.

[0013] Optionally, the system includes a time interface in addition to, or instead of, the state interface. The time interface is operative to receive time values indicative of hours worked on a particular component, and the database interface is operative to store the time values and associated component identifiers in the database.

[0014] Other optional interfaces include a link interface, a worker interface, a date interface, a site interface, a job interface, an activity interface, a drawing object interface, and a state property interface. The link interface is operative to receive links to files, the worker interface is operative to receive worker identifiers, the date interface is operative to receive date values, the site interface is operative to receive site identifiers, the job interface is operative to receive job identifiers, the activity interface is operative to receive activity identifiers, the drawing object interface is operative to receive drawing object identifiers, and the state property interface is operative to receive state property identifiers. The database interface is operative to store each of the above identifiers/values and associated component identifiers in the data base. The association between the identifiers/values and the component identifiers can be either direct or indirect, and can be either a many-to-one or a one-to-many relationship.

[0015] The system further includes query interfaces. In some cases, the query interface receives a query including a particular identifier and/or value, and the database interface searches the database, and provides identifiers/values associated with the received identifier/value. In other cases, the query interface receives a general query, and the database interface searches the database and provides a set of allowed identifiers/values.

[0016] The system further includes an optional viewer. The viewer includes a display, a user input device, and an application program interface. The application program interface enables the viewer to access the above described interfaces and query interfaces, and to write data to and receive data from the database. The viewer then displays a model file representation of the construction project based on the data received from the database. The user input device enables the viewer to incorporate identifiers/values selected by the user into the queries submitted to the query interfaces.

[0017] The system further includes an optional remote (e.g., hand-held) data entry device, whereby a user can collect data for subsequent transfer to the database. The remote data entry device includes a display, a user input device, and an application program interface. The application program interface enables the remote data entry device to access the above described interfaces and query interfaces. In one particular embodiment, the remote device is operative to retrieve sets of component identifiers, sets of state indicators, sets of worker identifiers, and/or sets of activity codes. The remote device then presents the retrieved identifiers to the user, so the user can select identifiers to be included in records (e.g., time entries, state changes, etc.) stored in the remote device and later transferred to the database.

[0018] An optional extractor extracts component identifiers from a drawing file, and provides the component identifiers to the component interface. The components are defined within the drawing file by the program that creates the drawing file.

[0019] A method of managing a construction project is also described. The method includes the steps of receiving a plurality of component identifiers from a user, associating an initial predefined state with each received identifier, storing the component identifiers and the associated initial states in a database, updating the states associated with the component identifiers in the data base, and retrieving the updated states from the database to determine the status of the construction project.

[0020] Novel data structures, application program interfaces, and graphical user interfaces are also disclosed, and are considered to be a part of the present invention.

DETAILED DESCRIPTION

[0110] The present invention overcomes the problems associated with the prior art, by providing a system and method for managing construction projects that facilitates the easy entry of project data, and provides current information regarding the status of construction projects. In the following description, numerous specific details are set forth (e.g., example commercially available application programs) in order to provide a thorough understanding of the invention. Those skilled in the art will recognize, however, that the invention may be practiced apart from these specific details. In other instances, details of well known database programming practices (e.g., searching operations) have been omitted, so as not to unnecessarily obscure the present invention.

[0111] FIG. 1 is a block diagram of a system 100 for managing construction projects according to one particular embodiment of the present invention. System 100 includes a primary server 102, a plurality of administration clients 104(1-m), a plurality of extraction clients 106(1-n), a plurality of viewer clients 108(1-p), and a plurality of field clients 110(1-q), all intercommunicating via an internetwork 112. System 100 further includes a plurality of remote devices 114(1-r) capable of communicating field clients 110(1-q).

[0112] Primary server 102 includes a database and files associated with one or more construction projects. Administration clients 104(1-m) facilitate the entry and/or retrieval of project data to and from server 102 by various personnel, including but not limited to those responsible for supervising construction, providing logistical support, reporting to customers, and so on. Extraction clients 106(1-n) are operative to extract information (e.g., drawing objects, object identifiers, etc.) from drawing files associated with construction projects, and to provide the extracted information to primary server 102. Extraction clients 106(1-n) are further operative to generate model files that include objects representing components (e.g., pipes, vents, support structures, etc.) of construction projects from computer-aided-design (CAD) files of the respective projects. Viewer clients 108(1-p) are operative to retrieve information from server 102, and to display the model files based on the retrieved data, such that the displayed model conveys information (e.g., the current state) related to the components. Field clients 110(1-q) are operative to provide data to server 102 from construction sites as projects at the respective sites proceed. Remote devices (e.g., hand-held, palm-top, etc.) are used by workers (e.g., foremen for the various trades) at a construction site to collect various data associated with particular components of the project, and to provide the collected data to field clients 110(1-q).

[0113] In this particular embodiment, internetwork 112 is a private wide-area-network (WAN). However, it should be understood that internetwork 112 can include any means to facilitate communication between server 102 and the other components of system 100, including but not limited to public networks, direct dial-up connections, wireless connections, docking stations, company intranets, and the like.

[0114] Further, the invention is not limited to any particular physical location of the particular components of system 100. According to one particular implementation, primary server 102 is located at the construction company headquarters in the IT department. Administration clients 104(1-m) can be scattered throughout various departments such as accounting, shipping and receiving, human resources, operations, and the like. Extraction clients 106(1-n) would likely be located in the engineering department, and viewer clients 108(1-p) would likely be distributed among the engineering and operations departments. As indicated above, field clients 110(1-q) are primarily intended for use on the actual construction sites. However, the foregoing distribution of components is intended only as an example, and it should be understood that the various components of system 100 can be located anywhere that is convenient for the staff that need to use them.

[0115] In the presently described embodiment, primary server 102 is an otherwise typical, commercially available server machine. Administration clients 104(1-m), extraction clients 106(1-n), and viewer clients 108(1-p) are otherwise conventional desk top computers. Field clients 110(1-q) are otherwise typical portable computers, and remote devices 114 are hand-held devices capable of communicating with field clients 110(1-q) via a docking cradle, an infrared connection, or the like. It should be understood, however, that the client components of system 100 can be hosted on other types of computing systems if desired. Further, two or more of the different client components can be hosted on a single computer. For example, a project manager might have a desktop machine that hosts an administration client 104 and a viewer client 108.

[0116] FIG. 2 is a block diagram showing primary server 102 in greater detail to include non-volatile data storage 120, one or more processing units 122, working memory 124 (e.g., random access memory), a user interface 126, and a network adapter 128, all intercommunicating via an internal bus 130. Non-volatile data storage 120 stores data and code that is retained even when primary server 102 is powered down. Typical examples of non-volatile data storage include read only memory, hard disk drives, RAID arrays, optical disk drives, and other types of removable media. Processing unit(s) 122 impart functionality to primary server 102 by processing the executable code stored in non-volatile data storage 120 and memory 124. Working memory 124 provides temporary storage for data and code being processed by processing units(s) 122. User interface 126 provides a means for a user to interact with server 102, and typically include such devices as a keyboard, a monitor, a printer, a pointing device, and the like. Network adapter 128 facilitates communication with the other components of system 100 (FIG. 1) via internetwork 112.

[0117] In order to clearly explain the operation of primary server 102 (and the subsequently described client components), the functionality of server 102 (or the respective client component) is shown representationally as code blocks in memory 124 (or the memory of the respective client component). Those skilled in the art will understand, however, that all of the code need not remain in memory 124 during the operation of server 102. Indeed, processing unit(s) 122 will typically shuffle portions of the code into and out of memory 124 (e.g., to/from non-volatile data storage 120) for execution as required during operation. Further, although the functional blocks in memory 124 are shown to be physically coupled to one another, those skilled in the art will understand that they are actually processes that communicate by calling one another of execution.

[0118] As shown in FIG. 2, memory 124 includes an operating system 132, one or more application programs 134, a database 136, a database application program interface (API) 138, and files 140. Operating system 132 is a low level program upon which the other programs run. In other words, operating system 132 provides an interface between higher level programs and the hardware of server 102. Application programs 916 are representative of word processing programs, graphics programs, accounting programs, and the like, which can be used in conjunction with or in addition to the programs of the present invention.

[0119] Database 136 stores data related to the status of construction projects. A particular embodiment of the present invention was constructed using MICROSOFT® SQL Server to assemble and maintain database 136. The particular structure and contents of database 136 will be described in greater detail below.

[0120] Database API 138 includes a set of commands that facilitate the reading and writing of data to and from database 136 by the client components of system 100. Files 140 include, but are not limited to, word processing documents, drawing files, scanned images, and accounting files. Particular files stored in files 140 can be associated with respective construction projects via database 136 by associating a link to the file with an identifier corresponding to the respective construction project, and writing a record including the identifier and the link to database 136. For example, a record stored in database 136 can associate an identifier corresponding to a valve in a plumbing system with a link to an image file showing the valve in files 140.

[0121] FIG. 3 is a block diagram showing extraction client 106 in greater detail to include non-volatile data storage 150, one or more processing units 152, working memory 154 (e.g., random access memory), a user interface 156, and a network adapter 158, all intercommunicating via an internal bus 160. Non-volatile data storage 150 stores data and code that is retained even when extraction client 106 is powered down. Processing unit(s) 152 impart functionality to extraction client 106 by processing the executable code stored in non-volatile data storage 150 and memory 154. Working memory 154 provides temporary storage for data and code being processed by processing units(s) 152. User interface 156 provides a means for a user to interact with extraction client 106, and typically includes such devices as a keyboard, a monitor, a printer, a pointing device, and the like. Network adapter 158 facilitates communication with primary server 102, or other components of system 100, via internetwork 112 (FIG. 1).

[0122] As shown in FIG. 3, memory 154 includes an operating system 162, a CAD application program 164, an extraction routine 166, one or more drawing files 168, one or more model files 170, one or more image files 172, and a database application program interface (API) 174. CAD application 164 is a program for creating drawing files 168 corresponding to particular construction projects. For example, a designer could use CAD application 164, via user interface 156, to generate of a drawing file 168 of a warehouse to be constructed. A particular drawing file can include graphical representations of some or all of the systems (e.g., electrical, plumbing, HVAC, structural, etc.) of the warehouse. Typically, drawing files 168 also include objects corresponding to specific components (e.g., a valve, a duct section, a structural beam, etc.) of the construction project that include additional data (e.g., size, material, manufacturer, etc.) associated with that component. A particular embodiment of the present invention was assembled using AUTOCAD® by Autodesk as the CAD application.

[0123] Extraction routine 166 is operative to extract information from drawing files 168, and to use the extracted information to generate associated model files 170, to generate image files 172, and to write information to database 136 via database API 174. Model files 170 are files that can be displayed with a viewer (e.g., NAVIS WORKS®) as a three-dimensional image of the construction project. Image files are two-dimensional images, of any convenient format, which depict selected portions of the construction project. An objects in a model file 170 or an image file 172 corresponds to one or more objects in an associated drawing file 168 from which it is extracted, and therefore also corresponds to components of the particular construction project represented by the drawing file 168.

[0124] In a particular implementation of the present invention, extraction routine is provided as a NAVIS® file export plug-in application for AUTOCAD® that has been modified to provide the functionality described herein. It should be understood, however, that extraction routine 166 can be integrated within the code of CAD application 164, or can be a stand alone application.

[0125] Using extraction routine 166, a user groups the objects of a drawing file into “ISOs”. As used herein, an ISO is generally interpreted to be a definition of a sub-portion of an entire construction project. The ISO definitions can include as many or as few of the components of the project as is convenient or practical for a particular project. For example, if the construction project is a warehouse, an ISO can be defined that includes an overhead door and all of the mounting hardware for the door. Virtually any useful criteria can be used to break a project down into ISOs. One example is to define each ISO to include objects that can be assembled and shipped to a construction site as a unit.

[0126] From the foregoing description of ISOs, it should be clear that each ISO can be understood to define a “component” of a construction project. Typically, a component defined by an ISO will include several smaller components which will correspond to objects (e.g., pipe fittings, vents, etc.) in a drawing file. However, it is not essential that an ISO include several objects. Indeed, it is even possible for an ISO to define a part of a construction project (e.g., a process) that does not correspond to a physical component of the construction project.

[0127] When extraction routine 166 generates a model file 170, the extraction routine 166 also writes data (e.g., an initial construction state) to database 136, using the assigned ISO numbers as identifiers to associate the stored data with the particular components of the construction project. The components represented in the model file are also associated with the respective ISO numbers, such that a viewer application can later retrieve updated data from database 136, and display each ISO of the model file based on the updated data, as will be described in greater detail below.

[0128] Extraction routine 166 also uses the ISO numbers as identifiers when generating image files 172. In particular, image files 172 are stored in files 140 of server102, and links to those files are written to database 136, using the respective ISO numbers as associated identifiers. Typically, image files 172 will include particular views of an ISO from CAD application 164. However, extraction routine 166 may generate image files 172 via other means, including but not limited to scanning in hand drawn pictures or photos associated with an ISO.

[0129] Image files 172 can be used for any purpose, but are primarily intended to convey visual information regarding an ISO to users without the capability of viewing memory intensive model files. For example, it is convenient for a foreman on a construction sight to be able to view graphical representations of ISOs to, for example, correctly identify ISOs for data entry purposes. However, it is impractical to provide full model viewing capabilities on remote devices 114.

[0130] FIG. 4 is a block diagram showing administration client 104 in greater detail to include non-volatile data storage 180, one or more processing units 182, working memory 184 (e.g., random access memory), a user interface 186, and a network adapter 188, all intercommunicating via an internal bus 190. Non-volatile data storage 180 stores data and code that is retained even when administration client 104 is powered down. Processing unit(s) 182 impart functionality to administration client 106 by processing the executable code stored in non-volatile data storage 180 and memory 184. Working memory 184 provides temporary storage for data and code being processed by processing units(s) 182. User interface 186 provides a means for a user to interact with administration client 104, and typically includes such devices as a keyboard, a monitor, a printer, a pointing device, and the like. Network adapter 188 facilitates communication with primary server 102, or other components of system 100, via internetwork 112 (FIG. 1).

[0131] As shown in FIG. 4, memory 184 includes an operating system 192, an accounting application 194, a purchase order management routine 196, an inspection tracking routine 198, a transmittal management routine 200, an employee management routine 202, a turnover packages routine 204, a vendor management routine 206, a client management routine 208, a receiving routine 210, a materials returns routine 212, a request for information (RFI) routine 214, a job status tracking routine 216, and a database interface 218. Accounting application 194 facilitates general accounting procedures such as accounts payable, accounts receivable, etc., but has the added capability of querying database 136, via database interfaces 218 and 138, such that client billing procedures can be based on job specific data such as percentage completion, and can provide job status reports that can be provided to clients to verify billing milestones. Further, accounting application 194 can track expenses, including but not limited to material costs, labor costs, etc., on a job-by-job, or even an ISO-by-ISO basis. Purchase order management routine 196 facilitates the issuance and tracking of purchase orders for required materials and supplies. Inspection tracking routine 198 tracks and records all required project inspections. Transmittal management routine 200 tracks and records transmittals to clients (e.g., drawings, specifications, inspection reports, etc. that are sent to clients). Employee management routine 202 facilitates the entry of employee data into database 136 and the generation of reports including work performed by employees on particular jobs. Turnover packages routine 204 generates detailed reports, on any desired aspect of a job, which are provided to clients during or upon completion of the job. Vendor management routine 206 facilitates the storage and retrieval of vendor information for vendors providing materials for a particular job. Client management routine 208 facilitates the storage and retrieval of information relating to the client (customer) for a particular job. Receiving routine 210 tracks the receipt of materials and supplies ordered for a particular job. Material returns routine 212 tracks the return of materials and supplies to vendors. RFI management routine 214 facilitates and tracks the generation of RFIs, transmittal of the RFIs to the clients, and receipt of the client's response. Job status tracking routine 216 entry and retrieval of information relating to the status of a job.

[0132] Each of the above-described routines has access to database 136, via database interface 218 and database API 138. Therefore, the various routines can provide near real-time information regarding any particular construction project that a company has undertaken. Further, the detail of the of the reporting is unprecedented in the prior art. For example, upon completion of a job, turnover packages can automatically generate a detailed report to be provided to the client. The report can include every detail of the project including, for example, the manufacturer of every component used, the date and a copy of every required inspection, a copy of every required certification, and so on. Further, reports detailing the user's (construction company's) costs can be instantly generated to an unprecedented level of detail, including, for example, which employees worked on each ISO, and for how long. The foregoing description of the functionality of the various administrative modules is general in nature. The full capability of the present invention will be apparent, however, in view of the detailed description of database 136 which follows with reference to FIGS. 11-58.

[0133] FIG. 5 is a block diagram showing viewer client 108 in greater detail to include non-volatile data storage 230, one or more processing units 232, working memory 234 (e.g., random access memory), a user interface 236, and a network adapter 238, all intercommunicating via an internal bus 240. Non-volatile data storage 230 stores data and code that is retained even when viewer client 108 is powered down. Processing unit(s) 232 impart functionality to viewer client 108 by processing the executable code stored in non-volatile data storage 230 and memory 234. Working memory 234 provides temporary storage for data and code being processed by processing units(s) 232. User interface 236 provides a means for a user to interact with viewer client 108, and typically includes such devices as a keyboard, a monitor, a printer, a pointing device, and the like. Network adapter 238 facilitates communication with primary server 102, or other components of system 100, via internetwork 112 (FIG. 1).

[0134] As shown in FIG. 5, memory 234 includes an operating system 242, a viewer application 244, a database API 246, a hyperlink list 248, a state list 250, and ISO list 252, and at least one model file 170. The primary purpose of viewer application 244 is to display model files 170 generated by extraction routine 166 (FIG. 1) in such a way that the displayed model file provides information to the user regarding the status of the job. Responsive to receiving input (e.g., a job identifier, model file selection, etc.) from a user via user interface 236, viewer application 244 retrieves an associated model file 170 from files 140. Next, viewer application 244 queries database 136, via database APIs 246 and 138, to retrieve a current construction state (e.g., in transit, installed, being inspected, etc.) associated with each ISO in model file 170. Then, viewer application displays the model file based on the retrieved states, such that the graphical representation of each ISO in the model file is indicative of the construction state of the component represented thereby. For example, a different display color can be associated with each particular construction state. Optionally, viewer application 244 can store and retrieve a list of display properties (e.g., line color, line type, etc.) to be associated with particular construction states.

[0135] Viewer application 244 can also display model file 170 in other useful ways, such as displaying only those ISOs that have a particular construction state. To do so, viewer application 244 queries database 136 for a state list 250 of all available states associated with the job represented by model file 170. Then, responsive to the user selecting one of the available states from state list 250, viewer application 244 queries database 136 to determine which of the ISOs are currently associated with the selected state. Then, viewer application 244 displays only those ISOs associated with the selected state.

[0136] Viewer application 244 can also display hyperlinks (and the linked files) associated with objects in model file 170. Responsive to a predetermined user input, viewer application 244 queries database 136 for a hyperlink list 248 of hyperlinks associated with the job represented by model file 170. Then, responsive to the user's selection of an object in model file 170, viewer application 244 presents the hyperlinks from hyperlink list 248 corresponding to the selected object. The user is then able to select a hyperlink from those presented to edit the hyperlink or to retrieve the linked file. Viewer application 244 can also receive new hyperlinks from a user, and write records to database136 associating the new hyperlinks with ISOs of the job.

[0137] Viewer application can also be used to update the construction states of components of the job. Responsive to a predetermined user input, viewer application 244 queries database 136 for state list 250, which includes all of the available states for the particular job associated with model file 170, and for ISO list 252, which includes a list of all ISOs associated with the job. Then, responsive to the user's selection of a particular ISO from ISO list 252 (or the user's selection of the corresponding graphical object), viewer application 244 presents state list 250 to the user for the user's selection of a new state to be associated with the selected ISO. Upon the user's selection of a state from state list 250, viewer application writes a record to database 136 associating the selected ISO with the selected new state.

[0138] It should be noted that the above-described update functions of viewer application 244 can optionally be performed by job status tracking routine 216 (FIG. 4).

[0139] FIG. 6 is a block diagram showing field client 110 in greater detail to include non-volatile data storage 260, one or more processing units 262, working memory 264 (e.g., random access memory), a user interface 266, a network adapter 268, and a remote device interface 270, all intercommunicating via an internal bus 272. Non-volatile data storage 260 stores data and code that is retained even when field client 110 is powered down. Processing unit(s) 262 impart functionality to field client 110 by processing the executable code stored in non-volatile data storage 260 and memory 264. Working memory 264 provides temporary storage for data and code being processed by processing units(s) 262. User interface 266 provides a means for a user to interact with field client 110, and typically includes such devices as a keyboard, a monitor, a printer, a pointing device, and the like. Network adapter 268 facilitates communication with primary server 102, or other components of system 100, via internetwork 112 (FIG. 1). Remote interface device 270 provides a means for transferring data between remote devices 114 and field client 110, and can include a device cradle, an infrared link, a wireless network connection, or any other suitable data transfer means.

[0140] As shown in FIG. 6, memory 264 includes an operating system 274, a data exchange routine 276, a database API 278, image files 280, employee list 282, ISO lists 284, activity lists 286, and activity data 288. Data exchange routine 276 is operative to retrieve image files 280 from files 140 (FIG. 1), and to query database 136, via database APIs 278 and 138, for employee lists 282, ISO lists 284, and activity lists 286 associated with jobs for a particular site. Although employee lists 282, ISO lists 284, and activity lists 286 may each include several list associated with different jobs and/or sites, it is anticipated that the number of list will be confined to a single site, if not a single job within a site, such that each list may be only a single list.

[0141] Data exchange routine 276 provides image files 280, employee lists 282, ISO lists 284, and activity lists 286 to remote devices 114, via interface 270, to facilitate the entry of data into remote devices 114, as will be described below with reference to FIG. 7. Data exchange routine 276 is further operative to receive activity data 288 from remote devices 114, and to transfer the received activity data 288 to database 136. Activity data 288 generally relates to work performed on a job, and includes without limitation an ISO identifier indicative of the component upon which the work was performed, an employee identifier indicative of the worker who performed the work, a date value indicative of the date the work was performed, a time value indicative of the time duration of the work performed, an activity identifier indicative of the type of work that was performed on the component, and a state indicator indicative of any changed construction state of the component.

[0142] FIG. 7 is a block diagram showing remote device 114 in greater detail to include non-volatile data storage 300, one or more processing units 302, working memory 304 (e.g., random access memory), a user interface 306, and a field client interface device 308, all intercommunicating via an internal bus 310. Non-volatile data storage 300 stores data and code that is retained even when remote device 114 is powered down. Processing unit(s) 302 impart functionality to remote device 114 by processing the executable code stored in non-volatile data storage 300 and memory 304. Working memory 304 provides temporary storage for data and code being processed by processing units(s) 302. User interface 306 provides a means for a user to interact with remote device 114. In embodiments where remote device 114 is a hand-held device, user interface 306 will likely include a touch screen display and a stylus, although other types of interface devices are certainly possible. Field client interface device 308 is complementary to remote device interface 270, and provides a means for transferring data between remote device 114 and field client 110. Therefore, field client interface device can also include a device cradle, an infrared link, or any other suitable data transfer means.

[0143] As shown in FIG. 7, memory 304 includes an operating system 312, a data entry routine 314, a data exchange routine 316, image files 318, employee lists 320, ISO lists 322, activity lists 324, and activity data 326. Data entry routine 314 facilitates the entry of activity data 326, via user interface 306, by a user. Data exchange routine 316 is similar to data exchange routine 276 of field client 110, and is operative to transfer data between remote device 114 and field client 110 in either direction.

[0144] Remote device 114 facilitates the collection of activity data 326 as follows. Initially, data exchange routine 316 receives image files 318, employee lists 320, ISO lists 322, and activity lists 324 from field client 110, via field client interface 308. Image files 318 are similar to image files 280 stored in field client 110, except that image files 318 need not include all of image files 280. Rather, it is anticipated that it will only be necessary to transfer a subset of image files 280 associated with one or more particular jobs to image files 318. However, this is not a limitation of the invention, and all of image files 280 can be transferred to image files 318 if needed. Similarly, employee lists 320, ISO lists 322, and activity lists 324 will include some or all of the list stored in employee lists 282, ISO lists 284, and activity lists 286.

[0145] Once employee lists 320, ISO lists 322, and activity lists 324 are transferred into remote device 114, data entry routine 314 uses the list to facilitate the entry of activity data 326 by a user. Data entry routine 314 presents the lists to the user via interface 306 (e.g., in a form with drop-down lists) so that the user can select an employee, an ISO identifier, and an activity type (e.g., welding, electrical installation, pipe fitting, etc.). Data entry routine 314 also facilitates the entry of a time value (indicative of the time worked) and a date value, and then writes the completed record to activity data 326. Data entry 314 also has the capability to display image files 318, which will be useful to the user in identifying and/or selecting the appropriate ISO numbers for data entries.

[0146] It is anticipated that a foreman or supervisor on the job site will continue to enter data in this manner as work is performed on components of the job for which he/she is responsible. Data entry routine 314 will accumulate the records in activity data 326 until such time as data exchange routine 316 is invoked to transfer activity data 326 to activity data 288 of field client 110, via field client interface 308. Although there is no requirement as to how often activity data 326 must be transferred, so long as memory 304 has sufficient capacity to store activity data 326, it is expected that it will be convenient to effect the data transfer at the end of each work day. Then, as soon as field client 10 writes activity data 288 to database 136, the entire enterprise will have the most current information possible regarding the status of the project.

[0147] It should be understood that list and data other than those specifically shown in FIG. 7 can be employed in remote device to facilitate any useful data entry. For example, a list of state indicators corresponding to predefined construction states can be presented to the user to facilitate the entry of records to update the current construction state of a component. Further, certain entries, for example the state change entry just described, will not necessarily require a value from each of the lists shown in FIG. 7. Thus, it should be clear that the particular types of data shown are not essential elements of the invention, and should not be construed as limitations.

[0148] FIG. 8A is a block diagram illustrating the flow of data according to one embodiment of the present invention. A users 340 can store and/or files in files 140 either directly (e.g., via administration client 104) or through one or more applications 342 (e.g., via extraction client 106 or viewer client 108). Similarly, user 340 can enter data into database 136 either directly or through an application. A user interface 344 is provided to facilitate direct data entry and retrieval by user 340, and an application program interface (API) 346 is provided to facilitate data entry and retrieval by application programs. Both user interface 344 and API 348 exchange data with database 136 via an underlying database interface 348.

[0149] User interface 344 includes any means whereby a user can enter data directly into or retrieve data from database 136. For example, typical database programs allow a user to enter data directly into the database tables, and also facilitate the creation of forms to facilitate the direct entry of data into the database. Further, these database programs facilitate the creation of reports to view the data in many useful ways. Accordingly, user interface 344 is understood to include without limitation such data entry forms and tables, and such reports. Of course, the particular content of the tables and forms, which will be described in greater detail with reference to FIGS. 11-58 and FIGS. 66-87, is considered to be an innovative aspect of the present invention.

[0150] The primary function of API 346 is to facilitate data entry and retrieval by extraction clients 106 and viewer clients 108. However, it should be understood that API 346 can also provide access to database 136 for applications other than those disclosed herein, and so is considered to be an innovative aspect of the present invention, which is not limited by the particular type application program using API 346. API 346 includes the following transactions.

[0151] AddISO

[0152] This transaction is used to add ISOs to database 136. The properties set in the request object are a model filename (with full directory path) and ISONumber. The ISO will be added to database 136 for the site and job indicated in the drawing file path, only if the ISO number does not already exist for that site and job.

[0153] AddISOHrs

[0154] This transaction is used to send timesheet information to database 136. Hours are stored in database 136 at the level of site number+job number+ISO+employee number+activity code+date. The properties set in the request object are the model filename (with full directory), ISO, employee number, activity code, date, regular hours, and overtime hours. The site+job+ISO must already exist in database 136 for this transaction to succeed. In addition, the employee number and activity code must exist in database 136. The ISO would have been placed there by extraction client 106, via the AddISO or AddDrawingObject transaction. The site, job, employee number and activity code are input via user interface 344. Note that the filename itself is not used by this transaction, only the site and job which are in the filename's directory. If there are already hours in database 136 for the key (site+job+ISO+employee number+activity code+date), then the hours sent will simply overwrite the previous hour value, and no error is returned.

[0155] DeleteISOHrs

[0156] This transaction is used by field clients 110 to delete all database 136 timesheet entries for a site+job, or a site+job+ISO, or a site+job+ISO+date, or a site+job+ISO+date+employee number. Which level of deletion is done depends on an enumerated type property DeleteType set in the request by the caller. This transaction can be used by field client 110 or remote device 114, for example, to “reset” the activity data entries in preparation for another send (another AddISOHrs), or if the wrong data was mistakenly sent.

[0157] The requestor sets the property DeleteType to indicate the level of deletion. The DeleteType settings (and associated properties to set) are as follows: bysitejob (drawingfile); bysitejobISO (drawingfile+ISONumber); bysitejobISODate (drawingfile+ISONumber+date); and bysitejobISODatePerson (drawingfile+ISONumber+date+employee number).

[0158] SetISOState

[0159] This transaction is used by remote device 114 or field client 110 to set a construction state for a site+job+ISO, as of a begin date and time. The begin date/time is intended to be when the ISO first entered that state. An ISO whose state has never been set is in the state 0 (undefined). If the site+job+ISO is not already in database 136, this transaction will fail. The properties set by the caller are filename, ISO, state, and AsofDate. (which contains both a date and a time). Only the directory portion of the filename is used, to determine the site and job. The filename itself is not used by this transaction.

[0160] QueryISOState

[0161] This transaction is used by viewer client 108 to retrieve ISOs' state information from database 136. It will return an ISO(s) state as of the requested date and time. The request can be made for a single ISO, or all ISOs for a site+job, or all ISOs for a model drawing file. The requester always sets the property AsOfDate (which contains both a date and a time) to the date and time for which the state information is requested. (i.e., query for an ISO state as of a date+time).

[0162] The requestor sets the property SelectionType to one of: bysitejob (to retrieve all ISOs for a site+job, i.e., all model drawing files within a directory); bydrawingfile (to retrieve all ISOs for a model drawing file); or bydrawingfileISO (to retrieve one specific ISO from a site+job). The properties the requestor sets to determine the selection set correspond to the SelectionType setting. The SelectionType settings (with the associated properties to set) are as follows: bysitejob (drawingfile); bydrawingfile (drawingfile); and bydrawingfileISO (drawingfile+ISONumber).

[0163] QueryISOHours

[0164] This transaction is used by viewer client 108 to retrieve an ISO's (or ISOs') total regular hours, total overtime hours and estimated hours from database 136. It will return the regular and overtime hours for an ISO(s) as of the requested date, along with the current estimated hours. The request can be made for a single ISO, or all ISOs in a model file, or all ISOs for a site+job. (i.e., all ISOs for all model files in a directory). The requestor sets the property AsOfDate to the date for which the hourly total is desired.

[0165] The requestor must also set the property SelectionType to one of: bysitejob (to retrieve ALL ISOs for a site+job); bydrawingfile (to retrieve ALL ISOs for a drawing file); or bydrawingfileISO (to retrieve one specific ISO from a drawing file). The properties the requestor sets to determine the selection set correspond to the SelectionType desired. The SelectionType settings (with the associated properties to set) are as follows: bysitejob (drawingfile); bydrawingfile (drawingfile); and bydrawingfileISO (drawingfile+ISONumber).

[0166] AddDrawingObject

[0167] This transaction will be used by extraction client 106 or viewer client 108 to add a single model file object, and its attachment files (e.g., hyperlinks), to database 136. Drawing file objects are keyed by site+job+drawing file+ObjectID. The calling program must ensure the object does not exist before it is added. The DeleteDrawingObject transaction can be used to do this.

[0168] This transaction will cause the ISO to be added, if it doesn't already exist, to an ISO master table of database 136, allowing other applications to do AddISOHrs and SetISOState transactions. Note that the same ISO cannot exist twice (i.e., in 2 model drawing files) for the same site+job. If the caller attempts to add the same ISO within a single site and job, for two different drawing files, the transaction will fail.

[0169] The properties which the requestor sets are: drawingFilename; ISONumber; ObjectID; and Attachment File (a collection of objects, one for each hyperlink defined for this drawingfile+objectID).

[0170] DeleteDrawingObjects

[0171] This transaction is used by viewer client 108 to delete all objects for a model drawing file from the database 136, or to delete one drawingfile+object from the database 136. The requester sets the enumerated property deletetype to indicate which level of deletion is being done. As noted above, drawing objects must be explicitly deleted before they can be re-added. The most efficient way to delete all drawing objects from a file is to use this transaction, with deletetype set to bydrawingfile, rather than individually delete each drawing object with separate transactions. The requester sets the property deletetype to indicate the level of deletion. The other properties which must be set correspond to the deletetype setting. The deletetype settings (with the associated properties to set) are as follows: bydrawingfile (drawingfile) and bydrawingfileobject (drawingfile+objectID).

[0172] DeleteDrawingObjectLink

[0173] This transaction will be used by viewer client 108 to delete just one attachment (link file) from a drawing object. The properties which the requestor sets are: drawingFilename; objectID; and LinkFileName (the attachment file name from AddDrawingObject).

[0174] QueryDrawingObjects

[0175] This transaction is used by viewer client 108 to retrieve data on drawing objects from database 136. Four different types of selection criteria are available. The requestor must set the property SelectionType to indication which is being used. This enumerated type SelectionType can be set to: bydrawingfile (to retrieve ALL objects for the drawing file); bydrawingfileISONumber (to retrieve all objects for an ISONumber); or bydrawingfileObjectID (to retrieve only one objectID). The properties the requestor sets to determine the selection criteria correspond to the SelectionType desired. The SelectionTypes (with associated properties to set) are as follows: bydrawingfile (drawingfile); bydrawingfileISO (drawingfile+ISONumber); and bydrawingfileObjectID (drawingfile+ObjectID).

[0176] QueryState

[0177] This transaction can be used by view client 108 or field client 110 to retrieve the description and current color setting for one state from database 136. States will be generally be referred to by an integer number within database 136, and in the API transactions described herein. However, for user display purposes, database 136 will also keep string descriptions corresponding to each numeric state. For example, State 1 is “Material Ordered”, State 16 is “System in Startup Mode”, etc.. Some of these descriptions are editable by the user administrator of database 136. Also, new states of any integer number and description may be added by the user administrator. Each state also has an associated color, which is a 32 bit integer set by the caller with the SetStateColor transaction.

[0178] In order to provide the most recent state description and color viewer client 108 or field client 110, this transaction is used to return the current description and color for one requested state number. The requestor sets the property state number, which can be any valid predetermined state number (e.g., 0-16).

[0179] QueryStates

[0180] This transaction is used by viewer client 108 to retrieve all currently defined states from the database 136, or a single state from database 136. The latter provides the same functionality as QueryState, above. The requestor sets the property QueryStatesType to one of: OneState (to retrieve state information for just one state) or AllStates (to retrieve info on all states defined in database 136. If the requester sets QueryStatesType to OneState, then the property state must also be set, to valid state number.

[0181] SetStateColor

[0182] This transaction is used by viewer client 108 to set the color associated with a given state. States will be generally be referred to by an integer number from 0 to 16. Color is also an integer property, of any value. The requestor sets the property statenumber, which in this particular example can be from 0 to 16, and the property color.

[0183] QuerySites

[0184] This transaction is used by viewer client 108 or field client 110 to retrieve the complete list of sites (e.g., construction locations) from database 136. The caller sets no properties before the call.

[0185] QueryJobs

[0186] This transaction is used by viewer client 108 or field client 110 to retrieve the complete list of jobs, for a single site, from database 136. The caller sets the property site number before the call.

[0187] CheckLogon

[0188] This transaction is used by viewer client 108 or field client 110 to see if their applications have been launched within the database 136 environment, and if so, which site the user which launched them is currently logged onto, and which job (within that site) is currently being referenced by that user. The caller sets no properties before executing this function, via its execute method.

[0189] Logon

[0190] This transaction is used by viewer client 108 or field client 110 to verify that a user has authorization to read and update database 136 for a particular site. The caller sets the properties site number, user, and password before the call, generally input from a user interface on the respective client system.

[0191] QueryISOs

[0192] This transaction is used by field client 110 to retrieve the complete list of ISOs for a site+job. The requestor sets the drawingfile property before the call. Note that the filename itself is not used by this transaction, only the site and job which are in the filename's directory.

[0193] QueryEmployees

[0194] This transaction is used by field client 110 to retrieve the complete list of employees for a given site. The employee number supplied with the AddISOHours transaction (see above) must be a valid employee number. The requestor sets the drawingfile property before the call. Note that the filename itself is not used by this transaction, only the site which is in the filename's directory.

[0195] QueryLaborCodes (Activity Codes)

[0196] This transaction is used by field client 110 to retrieve a complete list of labor codes for a given site. The labor code supplied with the AddISOHours transaction must be NULL, or a valid labor code (activity identifier). The requestor sets the drawingfile property before the call. Note that the filename itself is not used by this transaction, only the site which is in the filename's directory.

[0197] As indicated above, API 346 can be used by applications other than those specifically mentioned herein. Additionally, other useful transactions can be defined within API 346, depending on the particular functionality of applications (e.g., accounting applications, report generating applications, etc.) used in conjunction with database 136.

[0198] FIG. 8B is a relational diagram 360 illustrating the relationship between various processes according to one embodiment of the present invention. A database 362 and file repository 364 store the data and files used to manage various construction projects. Drawings for the construction projects are generated by a drawing program 366. An extraction routine 368 uses the drawings to define components of the project, to generate drawing and model files for the project, and to generate data related to the construction status of the defined components. Extraction routine 368 writes the model and drawing files to files 364, and writes the initial data to database 362. Hyperlinks and file path conventions relate the data in database 362 to the files in files 364. Optionally, extraction routine 368 can provide files (e.g., drawing files) directly to a data exchange routine 370.

[0199] Data in database 362 and files in files 364 are augmented and updated by data exchange process 370 and admin routines 372. Admin routines 372 can access database 362 and files 364 directly in order to add documents (e.g., purchase orders, shipping receipts, new drawings, etc.) to files 364 and data (employee data, activity codes, state codes, etc.) to database 362. Data exchange process 370 updates database 362 with data received from a remote data entry process 374.

[0200] Remote data entry process 374 collects data regarding work performed on components of construction projects, changes in the state of such components, and so on. The collected data is then transferred to data exchange process 370, which in turn transfers the data to database 362. Data exchange process 370 also facilitates the collection of data by remote data entry process 374, by retrieving lists (e.g., employee lists, activity codes, component identifiers, etc.) from database 362, and providing those lists to remote data entry process 374. Remote data entry process 374 then uses those lists to facilitate data entry. A viewer routine 376 retrieves model files from files 364, retrieves the updated data associated with the job that the model file represents from database 362, and then displays the model file based on the retrieved data.

[0201] FIG. 9 is a block diagram illustrating the hierarchical organization of physical models of the construction projects and, therefore, also of data within system 100. At the first level below the system level the data and files are associated with one of a plurality of sites 380. generally, each site 380 corresponds to a particular construction site for a particular client, although the association of a site 380 with one particular physical location is not a requirement. Each site 380 includes one or more jobs 382. Jobs 382 are typically defined to include, for example, the plumbing system, the heating system, the electrical system, and so on. However, it should be understood, that any useful definition can be used. Each job 382 includes one or more ISOs, which generally represent components of the particular job 384. For example, an ISO 384 might be defined to include a boiler and an attached valve manifold. Again, any useful definition is acceptable. Finally, each ISO 384 can include one or more objects 386. An example of an object 386 might be a single valve of the valve manifold of the previous example. Again, any useful definition is acceptable.

[0202] FIG. 10 is a diagram showing one suitable file structure 390 for files 140. File structure 390 includes a separate site directory 392 for each defined site. Each site directory 392 includes a separate job directory 394 for each job defined within the respective site. Each job directory 394 includes a documents directory 396 and a drawings directory 398. Document directories 396 store documents (e.g., purchase orders, RFIs, etc.) associated with the particular job corresponding to the job directory 394 in which the respective document directory 396 is located. Similarly, drawing directories 398 store drawing files (including model files) associated with the particular job corresponding to the job directory 394 in which the respective drawing directory 398 is located.

[0203] Note that file structure 390 is consistent with the hierarchical structure of the data shown in FIG. 9. This correlation provides an advantage in that the file path of a document or drawing file (e.g., \BaseDirectory\SiteX\JobY\Drawings\drawingfile.dwg) uniquely defines a particular job at a particular site. Therefore, as indicated above with reference to API 346 (FIG. 8A) the file path of a drawing/model file provides information useful in retrieving data associated with the drawing/model file from database 136.

[0204] FIG. 11 shows a Configuration table 1016 and a Users table 1017 of database 136. Configuration table 1016 stores data generally related to configuring the overall operation and functionality of database 136. Users table 1017 stores data generally related to users who are authorized to access database 136. Because of the nature of the data stored in Configuration table 1016 and Users table 1017, no relationships between the records of the tables are defined.

[0205] FIG. 12 shows an Email Log table 1018, an Email Log To table 1019, and an Email Log Attachment table 1020 of database 136. Email Log table 1018 stores data defining individual email messages originating from within database 136. Email Log To table 1019 stores data related to the recipients of emails sent from within database 136. Finally, Email Log Attachment table 1020 stores data generally related to any attachments included with emails sent from within database 136.

[0206] The arrow heads of the relational connectors in the figures are intended to illustrate the type of relationship between the records and fields of the tables shown. In particular, a single arrowhead indicates a “one” relationship, whereas a double arrowhead indicates a “many” relationship. Thus, the records in Email Log table 1018 have a one-to-many relationship to the records of Email Log To table 1019. In other words, each record in Email Log table 1018 can correspond to many records in Email Log To table 1019. However, each record in Email Log To table 1019 will correspond to only one record in Email Log table 1018. Email Log table 1018 also has a one-to-many relationship with Email Log Attachment table 1020.

[0271] FIG. 59 is a flow chart 2100 summarizing one particular method of managing a construction project according to the present invention. In a first step 2102, a drawing file corresponding to the construction project is provided. Then, in a second step 2104, groups of objects within the drawing file (ISOs) are defined to correspond to components of the construction project. Next, in a third step 2106, a drawing file is created for each defined ISO. Then, in a fourth step 2108, a model file is generated from the drawing file, and in a fifth step 1210 data associated with the ISOs and objects of the drawing and/or model files is written to a database. Next, in a sixth step 2112, the ISO and object data in the data base is updated. Then, in a seventh step 2114, the updated ISO and/or object data is retrieved from the database, and in an eighth step 2116 the model file is displayed based on the updated ISO and/or object data. Then, method 2100 ends.

[0272] FIG. 60 is a flow chart summarizing one particular method 2120 of performing eighth step 2116 (display model file) of method 2100. In a first step 2122, a particular state is selected.

[0273] FIG. 61 is a flow chart summarizing one particular method 2130 of performing fifth step 2110 (write data to database) and eighth step 2116 (display model file) of method 2100. In a first step 2132, an object is selected from the model file. Then, in a second step 2134, at least one hyperlink is created. In a third step 2136, a record associating the selected object and the hyperlink are written to a database. Next, in a fourth step 2138, an object is again selected from the model file. Then, in a fifth step 2140, the database is queried and all hyperlinks associated with the selected object are displayed. Then method 2130 ends.

[0274] FIG. 62 is a flow chart summarizing one particular method 2150 of performing sixth step 2112 (update ISO and object data) of method 2100 of FIG. 59. In a first step 2152, initial states are defined for the ISOs defined for a job. Then, in a second step 2154, it is determined whether any new work has been performed on any of the components of the construction project. If not, second step 2154 repeats until it is determined that new work has been performed on a component. Then, in a third step 2156, the amount of new work performed (e.g., a number of hours) is associated with the ISO corresponding to the component upon which the work was performed by writing a record to the database. Next, in a fourth step 2158 it is determined whether the work performed on the component resulted in a change in the state of the component (e.g., installation complete). If not, then method 2150 returns to second step 2154 until more work is performed on a component. If, however, a change in state has occurred, then in a fifth step 2160, a record is entered in the database associating an identifier of the component with the new state. Then, method 2150 returns to second step 2154 until more work is performed on a component.

[0275] FIG. 63 is a flow chart summarizing one particular method 2170 of performing third step 2156 (enter new hours) of method 2150 of FIG. 62. In a first step 2172, a list of component identifiers (ISOs) is retrieved. In a second step 2174, a list of descriptions associated with the ISOs in the ISO list is retrieved. Then, in a third step 2176, an employee list is retrieved. Next, in a fourth step 2178, an activities (e.g., labor codes and/or descriptions) list is retrieved.

[0276] The retrieved lists are then used to enter new hours. In a fifth step 2180, an ISO corresponding to a component of a construction project is selected from the ISO list. Then, in a sixth step 2182, an employee who has performed work on the component associated with the selected ISO is selected from the employee list. Next, in a seventh step 2184 an activity which the employee has performed on the component is selected from the activity list. Then, in an eighth step 2186 a date is entered, and in a ninth step 2188 a number of hours worked on the component by the employee is entered. Finally, in a tenth step 2190, a record is written to the database associating the selected ISO, the selected, employee, the selected activity, the entered date, and the entered number of hours. Then, method 2170 ends.

[0277] FIG. 64 is a flow chart summarizing another particular method 2200 of performing third step 2156 (enter new hours) of method 2150 of FIG. 62. In a first step 2202, one or more lists are retrieved from a database. Then, in a second step 2204, the lists are transferred to a portable device. Next, in a third step 2206, the list are used to enter records of work performed into the portable device. Then, in a fourth step 2208, the entered records are retrieved from the portable device. Finally, in a fifth step 2210, the retrieved records are written to the database.

[0278] FIG. 65 is a flow chart summarizing one particular method 2220 of performing fifth step 2160 (enter new state) of method 2150 of FIG. 62. In a first step, 2222, a list of valid states is retrieved from a database. Next, in a second step 2224, an identifier (ISO) corresponding to the component whose state is to be updated is selected from a list of valid ISOs. Then, in a third step 2226, a state corresponding to the new state of the component is selected from the retrieved state list. In a fourth step 2228, a date value indicative of the date that the state of the component changed is entered. Then, in a fifth step 2230, a record associating the selected ISO, the selected state, and the entered date is written to the database, and method 220 ends.

[0279] In the foregoing descriptions of the flow charts are by way of example. It should be understood that many of the steps are optional, even if not explicitly so labeled. Therefore, unless explicitly stated, the individual steps of the described methods are not considered to be essential elements of the present invention. Further, it should be understood that the particular order of steps shown may in many cases be altered, without undermining the usefulness of the particular method. Therefore, unless explicitly stated, the particular order of steps shown should not be considered an essential element of the present invention.
