Abstract: Systems and methods are described for automating creation and management of alignments, stations, and work zones related to civil construction projects. Alignments are generated and processed to include geographic coordinates for start and end points. A station equation and digital stations along the alignment are generated using the start and end points of the alignment. In some examples, work zones are generated based on the alignments. The work zones and relevant data signals are monitored for geographic proximity of the data signals according to rules which may trigger transmission of navigation alert changes to downstream data consumers. In some examples, delivered tickets or completed construction tasks are associated with the digital stations to maintain an as-built representation of the construction project.

Abstract: Systems and methods automatically populate a digital as-built database from information about loads of construction materials delivered to construction projects, even if load tickets for the construction materials lack data indicating locations to or from which respective the loads were hauled. Construction machine sensor data is automatically collected from on-project construction equipment and matched with a filtered set of digital material load tickets collected from suppliers who provided the construction materials. These matches are used to estimate locations where the delivered construction materials are ultimately placed in the construction projects, and these locations are added to the as-built database, in association with their respective load tickets. In some cases, inferences are automatically drawn to automatically smooth or adjust location information in the machine sensor data, for example based on load ticket data, historical equipment or inspection information, and/or other data sources.

Abstract: A construction material quantity certification system includes first and second electronic databases that store construction project data and contractor data, as well as data about a plurality of deliveries of construction materials, including source records that identify sources of the delivered construction materials and chain of custody data. A server is coupled to plurality of devices, such as vehicle weight scales, configured to provide data about respective quantities of construction materials loaded onto respective vehicles. The server automatically obtains data about the respective quantities of construction materials from the plurality of devices, stores the data in the second database, associates each delivery to an associated contractor and to an associated project, updates the chain of custody data and, in response to receipt of a user input, uses data in the databases to automatically store a construction material quantity certification traceable to the source records of construction materials.

Abstract: A database reconciliation system stores construction project data, including project specification data for each of a plurality of projects and contractor data for each of a plurality of contractors. The system enables parties to make changes to the project specification data during the course of a project. The system also stores, and receives new, information about a plurality of deliveries of construction materials to respective construction sites. The system automatically associates each delivery of a delivered construction material to an associated contractor and to an associated project. The system may make inferences, based on past deliveries, to make the associations.

Abstract: A database reconciliation system stores construction project data, including project specification data for each of a plurality of projects and contractor data for each of a plurality of contractors. A server automatically receives observational data from a set of construction devices and stores the observational data in an electronic database. Each observational datum represents an aspect of a respective construction site, such as activity by construction equipment. The server associates the observational data with contractors, and a data reconciliation module automatically associates the observational data with projects. A comparator automatically identifies a respective project specification requirement in the project specification data of the associated project for which the observational datum provides evidence that the project specification requirement has been met.

Abstract: A digital chain of custody system resilient to wireless connectivity disruption includes an electronic database that stores electronic load tickets, a server, and one or more user communication devices wirelessly coupled to the server, examples of which include a sender communication device, a trucker communication device, and a receiver communication device. The receiver communication device and/or the server accepts a portion, less than all, of a load ticket identifier and uses a heuristic to identify a corresponding electronic load ticket in the database. In some embodiments, the receiver communication device stores information until wireless connectivity is restored, thereby enabling communication of the electronic load tickets, despite lack of wireless connectivity.

Ones of the user communication devices display barcodes that encode contents of respective electronic load tickets, and other ones of the user communication devices image the barcodes and decode the barcodes into digital representations of the electronic load tickets, thereby enabling communication of the electronic load tickets, despite lack of wireless connectivity.
