Control and accountability at a construction site affect efficiency, productivity, and ultimately costs and profitability. Security, access control, automated process management, secure, centralized real time records and data, and accountability at construction sites are often lacking or lax.
In many instances, individuals may come and go from construction sites freely. Moreover, there often are no security mechanisms for protecting the construction sites after hours. Access to a given construction site is typically controlled by the presence of supervisors at the site. Unfortunately, such supervisors may find it difficult to monitor and control access of all of the individuals coming and leaving from the construction site, and any one supervisor is not present on the site twenty-four hours a day, seven days a week. With a human supervisor, there is not a continuum of information or effective transfer without loss of data and information. Construction sites have multiple stakeholders who may be present at the same time or at different times, which further complicates control and accountability. Moreover, records of individuals and materials entering and leaving from the construction sites are not typically recorded on an ongoing basis and are seldom part of a record for all current and future stakeholders.
Control and confirmation of deliveries at construction sites is limited, requiring the mere signature or sign off of any individual on the construction site in order for the deliveries to be accepted, or in many cases, deliveries are made to unattended sites with delivery drivers' self-verification. Unattended deliveries are in jeopardy of theft. Deliveries may arrive unscheduled, out of sequence, and/or delayed to sites creating delays, and the records of deliveries may be limited, often consisting of paper receipts. The deliveries may be made regardless of weather conditions, resulting in some materials being subject to rain and other weather conditions that may affect the materials that are delivered. This can result in legacy issues for warranties and quality. At large sites, errors may occur with deliveries to the wrong location or wrong contractor as different trades may use common materials.
Construction sites are some of the most dangerous places to work. They are difficult to control, secure, and provide accountability and coordination between the multiple stakeholders over a complex and complicated process. Access to controlled areas of a construction site is difficult to set, maintain, and monitor. Despite regulations and best efforts, many of the workers may not be covered by Workers Compensation Insurance. Safety briefings, appropriate individual safety equipment, disclosure lists of dangerous or hazardous materials with corresponding emergency procedures are difficult to locate on most construction sites, if they even exist. Use of tools and equipment by unlicensed, untrained, or uncertified workers is common, and may result in serious accidents.
Construction workers are the lifeblood of a construction site. Accounting for their comings and goings, verifying their licensure, confirming their payroll, and even confirming their location on the construction site is difficult. Confirmation of real time progress to optimize and improve efficiency and scheduling requires a constant and coordinated supervisory presence.
The exemplary embodiments described herein attempt to provide solutions to the problems discussed above. In accordance with an exemplary embodiment, a site supervisor system is for use at a construction site.

The processing logic may generate an alert when an individual is in a prohibited area as defined by the geofencing.
The site supervisor system may include a weather station for providing weather information. More generally, the site supervisor system may include a source or interface for providing weather information. There may be in some embodiments software executed by the processing logic for obtaining current weather information at the site supervisor system, such as from a weather service. The current weather conditions may be recorded along with a current sequence of construction at the construction site.
The site supervisor system may store permission information regarding the permissions granted to individuals for the construction site. The site supervisor system may use the processing logic for accessing the permissions and for reviewing the location information to determine whether to grant access to at least one tool, equipment, power, water, natural gas, or other utilities, or areas at the construction site. The processing logic may control at least one smart lock to grant or deny access to at least one of the tools, equipment or areas of the constructions site. The processing logic may examine a current time and/or date in determining whether to grant access. The processing logic may examine a current time relative to a permitted time range in which the individuals are granted access to at least a portion of the construction site in determining whether to grant access. Current weather conditions may also be consulted in determining whether to grant access.
The site supervisor system may include a computing device with a display and an input mechanism for providing input to the computing device. The display may be a touchscreen display. The site supervisor system may include power outlets for providing power. The processing logic may monitor and record power usage via the power outlets in the storage. A control mechanism may be included in the site supervisor system for controlling access to at least one additional utility other than power (such as gas, water, etc.). The control mechanism may physically block or grant access to the power supply plug(s). For example, a door or gate may be provided to control access to the power supply plugs. The control mechanism may instead in some embodiments control access by controlling whether power is provided to the plug(s). The site supervisor system may include sensing and/or scanning technologies for delivery of items to the construction site. The sensing technology may be, for example, a Near Frequency Communication (NFC) device, a bar code scanner, a QR code scanner, radio frequency identification (RFID) or ultra-high frequency (UHF) detectors. The site supervisor system may be contained within a kiosk.
The processing logic of the site supervisor system may be configured to gather worker's compensation information and report any resulting worker's compensation claim. A video conference to a designated party may be initiated by the processing logic to gather the worker's compensation information and report any resulting worker's compensation claim. The processing logic may be configured to gather information regarding an injury at the construction site and to report the injury to a designated party. A video conference may be initiated by the processing logic to gather the information regarding the injury and to report the injury. The processing logic may be configured to provide a user interface for reporting any injuries or an absence of injuries for a time period.
A display may be provided as part of the site supervisor system for displaying information for treating an injury. The display may also display information regarding handling of hazardous materials. The site supervisor system may include one or more cameras. The processing logic may enable an external party remote from the construction site to view a live feed from the cameras.
In accordance with another exemplary embodiment, a site supervisor system is provided for use at a construction site. The system includes sensing technology for sensing at least one item being brought to the construction site. The system includes a storage device and processing logic. The processing logic is for processing information sensed by the sensing technology to establish an identity and a quantity of at least one item. The processing logic stores information regarding the identity and the quantity of at least one item in the storage device. The processing logic may be configured to confirm delivery of items at a designated location.
The system may include tracking technology for tracking a location of at least one item at the construction site. The tracking technology may be Near Frequency Communication (NFC) technology, GPS-based technology, radio frequency identification (RFID) technology, ultra-high frequency (UHF) technology and/or beacon-based technology. The sensing technology may be used for sensing at least one item being relocated to an unapproved area or being removed from the construction site. The processing logic may process information sensed by the sensing technology to identify the at least one item being removed from the construction site and a quantity being removed. This information is stored within the storage device by the processing logic. The sensing technology may be a bar code reader, a QR code reader, an RFID reader, a machine vision system or the like. The system may be in a kiosk.
In accordance with another embodiment, a method is performed by a site supervisor system at a construction site. The site supervisor system includes an image capture device, processing logic and a storage device. Per this method, an image of an individual is captured with the image capture device at the construction site. The processing logic is used to perform facial recognition on the image of the individual to attempt to identify the individual. Where the facial recognition fails to identify the individual, the system may ask for verification using the screen input device. Where the identity of the individual fails to be confirmed in any one of the methods, access to the construction site, or a portion thereof, is denied. Where the facial recognition identifies the individual, based at least in part on the determined identity, access may be granted or denied to the construction site or a portion thereof.
Permission information for the individual may be stored in the storage device. This permission information may be accessed in granting access or denying access to the individual. The permission information may include time and date information for which the individual is granted access to the construction site, or a portion thereof. The grant or denial may be based in part on the current date and time. The current weather conditions may also be consulted in granting or denying access to the individual to the construction site or a portion thereof. The processing logic may perform geofencing such that the individual is granted access to an area of the construction site but not to another area of the construction site.
In accordance with an exemplary embodiment, a method is performed by a site supervisor system at a construction site. The site supervisor system includes a biometric-based identification device for identifying an individual based on biometric data. The site supervisor system also includes a storage device for storing permission information and processing logic. Per the method, biometric data is obtained from an individual via the biometric-based identification device. The biometric data is processed with the processing logic to attempt to determine the identity of the individual. Where the identity of the individuals is determined and the permission information indicates that the individual is entitled to access, at least one smart lock is controlled to grant access to at least one tool, piece of equipment or area of the construction site. Where the identity of the individual is not determined or where the permission information indicates that individual is not to be granted access, at least one smart lock is controlled to deny access to at least one tool, a piece of equipment or an area of the construction site. The obtaining of the biometric data may comprise capturing an image of the individual, and the processing of the biometric data may comprise performing facial recognition of the image to attempt to determine the identity of the individual. The biometric data may be, for example, one of fingerprint data, retinal scan data, voice print data or hand scan data.
In accordance with an exemplary embodiment, a method is performed by a site supervisor system at a construction site. The site supervisor system comprises a biometric-based identification device for identifying an individual based on biometric data. The system also includes processing logic and a storage device for storing permission information. In accordance with the method, biometric data is obtained from the individual via the biometric-based identification device. The biometric data is processed with the processing logic to attempt to determine the identity of the individual. Where the identity of the individual is not determined, if the permission information indicates the individual does not have permission, the system may deny access to one or more power sources. Where the identity of the individual is determined and the permission information indicates that the individual has permission to access one or more power sources, access is granted to the one or more power sources.
The site supervisor system may have at least one power plug and granting access may comprise providing power to at least one power plug and physically providing access to the at least one power plug. Denying access may comprise providing no power to at least one power plug and/or physically blocking access to the at least one power plug. The power plug may include a first power plug providing power at a first voltage level and a second power plug providing power at a second voltage level. Granting access may comprise granting access for only one of the power plugs based on projected voltage level needs for the individual in some instances. In other instances, all of the power plugs may be accessible or not accessible, such as when a gate or door is used to control access. How much power is consumed by the individual and over what time period may be recorded in the storage device.
In accordance with an exemplary embodiment, a method is performed by a site supervisor system at a construction site. The site supervisor system comprises a computing system and processing logic that allows for machine learning to improve techniques and procedures.
In accordance with an exemplary embodiment, a site supervisor system includes a processing logic and a storage. The system performs a method. The method includes receiving information at the site supervisor system from a wearable worn by an individual on a residential construction site. The information may be, for example, location information or biometric data. Examples of biometric data include heart rate, respiration rate, body temperature and blood pressure. The received information is stored and analyzed by the processing logic to determine whether an action needs to be taken based on the received information. Example actions include triggering an alarm, sending a communication to the wearable to trigger an alarm, or contact a supervisor.
Exemplary embodiments provide a site supervisor system for providing security and controlling access to a construction site. The site supervisor system may monitor and record information regarding individuals entering and leaving the construction site. The site supervisor system may also monitor the perimeter of the construction site to provide security, especially during non-working hours. The site supervisor system may use biometric-based identification devices to confirm the identity of individuals entering or leaving the construction site. In addition, the biometric-based identification devices may also be used to identify individuals on the perimeter of the construction site.
Site supervisor systems at nearby construction sites may be interconnected using image capture devices, such as still cameras or video cameras, to provide security not only to the site on which it is stationed, but nearby sites as well. The processing of images from the multiple interconnected site supervisor systems may be performed via processing logic to identify security issues.
Confirmation of actual workers on site, and correspondingly, coverage by workers compensation insurance, licensing of workers, training for tools and jobs, and possession and usage of appropriate safety equipment is elusive. Onsite accident and claims management with immediate access to emergency care facilities and hazardous materials protocols is rare.
A system utilizing biometrics for verification of actual workers on the construction site to correspond with professional licenses and work certifications for verified payroll and insurance coverage would optimize processes and ensure coverage. Onsite verification of processes, inspections, completions and deliveries with automated adjustments and notifications with confirmation would ensure increased productivity. Real time construction plans with corresponding training and construction manuals would improve quality control and efficiency but rarely exist.
Automated verification of quantities, quality, and correct product deliveries along with after delivery tracking of materials with accountability is seldom used. Designated delivery areas with geofenced control and tracking of materials once delivered would help prevent loss. Confirmation of products integrated at a construction site provides transparency regarding sourcing, warranties, as well as future reference during the structure and individual products life of use.
The site supervisor system seeks to identify all individuals entering or leaving the construction site and persistently records this information in a storage, such as in a database. Such records may be useful in a number of different contexts. The biometric-based identification device may be a camera or other image capture device that obtains a facial image of a party. Facial recognition is performed on the captured facial image to attempt to identify the individual. Alternative biometric-based identification devices, such as voice recognition systems, retinal scans, fingerprint scanners, hand scanners, voice print devices and the like may be utilized in the alternative or in addition to other biometric devices. As a last resort, the computing logic may allow authorized individuals to manually enter the presence of another authorized individual.
The site supervisor system may record the time of arrival and the time of departure of individuals from the construction site. The site supervisor system may also record the date and current weather conditions. As such, the site supervisor system may confirm that the workers were at the construction site for the intended time windows and can record the hours that the workers worked to ensure that the workers are paid correctly. The site supervisor system may also compare the worker arrival and departure information to ensure that the worker arrives in a timely fashion and on the proper date. The weather information may be used to modify the schedule for workers so that workers are not working during inclement weather and to record the weather conditions at the time that the worker worked. Additionally, the processing logic may prevent work from being performed if said work would violate manufacturer guidelines for installation/application. The recorded information may also be useful in providing or disproving insurance claims or worker's compensation claims. The recorded information may also be useful to confirm installations or adherence to manufacturer specifications related to temperature or weather-related conditions.
If the site supervisor system determines that an unidentified individual attempted to enter the construction site, the site supervisor system may take the appropriate responses, such as sending notifications, triggering alarms and/or contacting law enforcement authorities or security personnel. The decision as to the appropriate response may be determined by, the date, the time current weather conditions, or related factor.
The site supervisor system may also control access to tools, equipment, materials and areas of the construction site. As to tools, equipment and materials, the site supervisor system may confirm the identity of an individual and grant access to certain tools and equipment using smart locks and/or other technology. The site supervisor system may limit the dates and duration of access to the tools/equipment such that the tools/equipment must be returned within the specified date/time window.
The smart locks may also be used to limit access to certain portions of the project under construction. An individual's right to a portion of the construction site may be dictated by permissions that are stored through each party involved in the construction process. This may eliminate keyed entry during the process and provide further verifications of individual or group access.
The individuals on the construction site may be prompted to wear certain wearables that provide useful information to the site supervisor system. For instance, individuals may be prompted to wear location tracking devices, such as GPS devices, Bluetooth, radio frequency identification (RFID) devices, ultra-high frequency (UHF) and/or beacon-based devices. The use of the wearables helps to perform geofencing within the construction site. The location tracking provided by the wearable helps the site supervisor system to monitor the location of individuals on the construction site on an ongoing basis. The permissions may define what portions of the construction site an individual may access. Ongoing monitoring may indicate that an individual is attempting to enter a location where the individual is not permitted. This may trigger a response, such as an alarm, a notification or even contacting of security or law enforcement officials. Individuals may be required to wear vests or other wearables that contain signaling capabilities. In such an instance, a signal may be sent to the vest or wearable to trigger a visual or audio cue that the individual is not in a permitted area. In addition, individuals may be requested to wear wearables that track biometric information, such as heart rate, body temperature, respiration rate and blood pressure. This information may be tracked and stored on an ongoing basis. When the biometric data gathered from these wearables are outside an acceptable range, which may indicate physical danger or injury, appropriate response actions may be taken such as notifying the individual, notifying a supervisor and/or contacting medical personnel. Collected data may be used to verify a multitude of factors such as reported accidents, incidents of theft, hours worked, and the like. The individuals on the construction site may be prompted to wear certain safety equipment related to their assigned tasks. The confirmation of the safety equipment may be useful in the prevention of accidents or in the prevention or lessening of injuries in the event of an accident.
The site supervisor system may track materials. When a delivery is made, the delivery person may enter delivery notes and the delivered materials may be scanned or read to confirm the quantity and nature of what has been delivered. This information may be recorded. Additional information, such as current weather conditions may also be recorded. The site supervisor system may track the movement of materials, tools and equipment at the construction site. Scanning technology such as RFID readers, UHF readers and the like may be utilized to assist the location tracking for tools, equipment and materials. The tracking of materials helps reduce the risk of theft. For example, the tracking solution may indicate instances of possible theft, such as when the materials are leaving the construction site when the removal of the materials is not appropriate.
The site supervisor system may allow for the establishment of one or more geofenced delivery zone areas. These areas could be monitored and established with additional access restrictions to individuals to further prevent loss or damage of materials.
The site supervisor system may control access to power by individuals of the construction site. The site supervisor system may provide a number of power outlets and may grant access to the power outlets as warranted. The use of power is recorded by the site supervisor system. Different levels of voltage may be provided as required. Parties using the power outlets may be billed appropriate amounts based upon the recorded power usage.
The site supervisor system may also interface with the inspectors such that an inspector may enter notes and related details of an inspection. The site supervisor system may allow the inspector to capture images of notes, forms, and the like using various solutions.
The site supervisor system gathers a great deal of information over the course of time. At least a portion of this information is persistently stored to compile a record of activities at the construction site. This record can be useful to prove activities after the fact. The activities that are recorded may drive workflow and scheduling at the construction site to improve efficiency and productivity Storage of information also maintains records in the event of a malfunction or power outage.
It should be noted that in alternative embodiments, the supervisor system need not be implemented as a kiosk. Instead, separate components that are not housed in a common housing may be utilized in some alternative embodiments.
The site supervisor system 130 may be implemented in a distributed fashion and may include an alternative energy source 140. For example, solar panels, wind turbine(s), a battery or the like may be used. In a kiosk implementation, the alternative energy source may be physically affixed to the kiosk. For example, solar panels or a cable to a wind power source could be affixed to the kiosk. Alternatively, a power line leading to the alternative energy source may be connected to the kiosk to provide power for the kiosk.
The site supervisor system 130 may include various scanners and readers 142, such as those described above relative to kiosk. The site supervisor system 130 may include a utility supply and control 144 and a mechanism for turning the utilities, such as power, gas and/or water, on and off under a programmatic control. The site supervisor system 130 may include an internet data supply control 145 and a mechanism for turning the access to this service on and off under a programmatic control. Programmatic control may be provided to grant or deny access to such resources. The site supervisor system 130 may include an antenna 146 for wireless communications signals to receive and transmit. The site supervisor system 130 may include a gyroscope 148 to monitor any moving of the system. The gyroscope 148 may indicate motion indicative of whether someone is trying to move or tilt the kiosk. Logic may be provided to send a notification in such an event where the gyroscope indicates substantial enough movement. The site supervisor system 130 may include a weather station 150 to measure current weather conditions, such as temperature, wind, precipitation, barometric pressure and the like. Input from the weather station 150 may be used to inform decision making by the site supervisor system in some instances. Alternatively, the weather may be collected via software, such as from a weather service or other weather source. Similarly, the site supervisor system 130 may include a wet bulb globe temperature device or a source of wet bulb globe temperature data 141. Wet bulb globe temperature is a measure of heat stress in direct sunlight, which accounts for temperature, humidity, wind speed, sun angle and cloud cover (solar radiation).
The computing device may include a display 206, such as an LCD display, an LED display or other types of display devices on which video information may be displayed. The computing device 200 may include a network adapter 208 for interfacing with networks and a modem 210 for communicating wirelessly, over telephone lines or cable lines with remote devices.

In particular, the processing logic 202 may execute programs 214 stored in the storage and may access and store data 216 relative to the storage device 204. The computational functionality of the site supervisor system described herein may be realized by the processing logic 202 executing the programs 214.
A list of hazardous materials at the site may be activated by activating element 232. This list is updated as hazardous materials are delivered, removed or consumed. Access to hazardous materials may also be controlled via the site supervisor system 130.
The user interface on display 206 (
The user interface on display 206 may include a dangerous tool activatable element 236. Activation of this element 236 causes the display of a list of dangerous tools on the construction site. An individual must have the proper authorization or certification to use such dangerous tools. The authorization or certification may be stored with the permissions.
The site supervisor system 130 may include coding software which allows each tool to be assigned to authorized personnel. Utilizing this coding along with smart locks as previously mentioned, the site supervisor system 130 either unlocks or prevents access.
Selection of the worker's compensation activation element 238 may be required at the end of each work day or when an injury occurs.
Delivery personnel may activate the delivery activatable element 226 (
As shown in
As was discussed above, the site supervisor system controls access to the construction site.
If there is not a match 406, a manual process may be executed, or an alternative authentication process may be deployed 416. If this alternative authentication fails to produce a match 406, access to the construction site may be denied 408. In addition, a notification may be sent to a responsible party and/or an event may be triggered, such as contacting security or law enforcement officials 410. If the alternative authentication process produces a match, the process proceeds to 412.
The site supervisor system may store permissions for each individual. These permissions may identify the dates and times where the individual is given access to the construction site. In addition, the permissions may specify what tools, equipment or materials the individual is allowed to access. The permissions may specify whether the individual is allowed to use a power supply and may specify what portions of the construction site the individual is permitted to access. These permissions may be accessed to determine the permissions for the identified individual 412. If the permissions indicate that access is permitted 414, the individual may be granted access to the construction site 418.
As was mentioned above, when an individual attempts to access the construction site and is not granted access, certain events may be triggered (see 410 in
As was discussed above, individuals entering the construction site must subject themselves to collection of their biometric data to confirm their identity before they are granted access to the site. One type of individual is a contractor.
As was discussed above, the wearables may be used to track the location of individuals on the construction site and to gather biometric data. In addition, the wearables may serve as a mechanism for communicating with the individual or communicating information regarding individuals to parties with certain responsibilities over the constructions site.
The use of the wearable to track location helps to facilitate geofencing in exemplary embodiments. The geofencing enables the site supervisor system to track and limit access to locations of individuals at the construction site. The construction site may be partitioned into areas where different permission rights are given for the various areas. For example, a plumber may be given access to the kitchen and the bathrooms of a project under construction but may be prohibited from being in the living room or the roof. As shown in
To help illustrate an example of geofencing,
Once individuals at the construction site are finished with their assigned tasks, they may be required to return the wearables.
As was discussed above, the site supervisor system may control access to electrical power at the construction site. This may be a significant issue in conventional construction sites where a great deal of power may be used by parties without paying for the power or parties may use power during non-working hours.
As was mentioned above, the wearables provide biometric data regarding individuals of the construction site. The site supervisor system may monitor this information and prompt action under certain circumstances.
As was mentioned above, the site supervisor system, enables tracking of equipment, tools and materials at the construction site.
As was mentioned above, the site supervisor system helps monitor and control deliveries to the construction site.
As was discussed above, the deliveries may utilize various scanning and reader technology. In
