Gilbane Building Co. has selected Trunk Tools as its enterprise-wide construction site Artificial Intelligence partner, agreeing to a seven-figure rollout of the startup’s TrunkSubmittal, TrunkText, and TrunkSOP agents. The deployment will extend across more than 200 projects nationwide over the next two years, according to Trunk Tools and the contractor. The move standardizes a set of Artificial Intelligence assistants for field and project teams, with the stated goal of improving submittal quality and speeding routine workflows at scale.
The decision follows the debut of TrunkSubmittal, which launched at ENR FutureTech in May and became generally available on July 1. Gilbane adopted the tool on 30 active projects over the summer and used it to review more than 2,000 submittals in three months, reporting improved quality of materials sent to architects. Since July, Trunk Tools found that 72 percent of submittals on Gilbane projects using TrunkSubmittal were non-compliant, 25 percent were partially compliant, and only 3 percent were fully compliant. By flagging issues early, teams reduced re-submissions and shortened submittal cycle times by nearly 50 percent. The contractor said these checks helped prevent requests for information, schedule delays, and downstream quality problems.
Gilbane leadership framed the enterprise rollout as part of a broader push to bring innovation to the field and support efficient, data-driven work. Company executives said the agents help optimize efficiency by automating bureaucratic workflows so teams can focus on core tasks. Field leaders characterized TrunkText and TrunkSubmittal as game changers for day-to-day operations, while the operations technology group reported that the tools have improved the jobsite experience and kept the company ahead of the curve in technology adoption and customer service.
Trunk Tools also introduced TrunkReview, a new agent designed to assist project managers with bulletin review by analyzing drawing revisions. The company said it uses proprietary large language models to analyze construction drawings. Trunk Tools CEO Sarah Buchner said the enterprise agreement demonstrates return on investment at scale and positions the partnership as a foundation for the next generation of Artificial Intelligence in construction, spanning submittals, drawings, and other workflows.
