Struction Raises a $5M Seed Round and Launches Preconstruction Map for General Contractors.

Today we’re announcing two major milestones for Struction: (1) We raised a $5M Seed round, and (2) We’re launching Struction’s Preconstruction Map for General Contractors.The round was led by Spider Capital, with participation from Eniac Ventures, Gradient, and a group of strategic operators. It funds one thing: the preconstruction operating system, built on Map.Map is like Google Maps, but for your drawings and specs.It generates the core outputs you expect from any AI preconstruction tool – scopes of work (bid forms), RFIs, risks, scope gaps, and derived quantities – but puts every output on one surface, with a line drawn back to the exact drawing or spec it came from. Every output. No black box.Three things make it different:1. AI you can audit. The estimator’s job is shifting from manual extraction to verification and judgment: every AI output is visually traceable to its source. Builders want accountability from AI before they want capability. We built both.2. New interface for every project. No two projects produce the same Map. Struction’s intelligence assembles itself around your set: custom software generated in real time.3. Chat that knows the whole set. Map embeds every detail of the drawings, specs, and BIM; it actually knows more about the project at once than any single estimator can.“This will save me anywhere from half a day to a week depending on the scale of the project… clock time, not individual time.” - Chief Estimator at ENR Top 20 GC“You’re looking at the potential savings of 3-4 days [per bid]… That’s pretty damn powerful.” - Sr. Estimator at ENR Top 10 GCIt’s easy enough to run with a game controller. And you can try it free; no demo gatekeeping, no sales call: https://struction.co
