We bring big-GC estimating discipline to the builders who need it most — without the overhead of a full-time preconstruction department.
PreconWorks was founded by working preconstruction professionals who spent years building budgets, leveling subs, and writing proposals for commercial projects. We saw the same gap everywhere: small and mid-size GCs are expected to estimate like the big firms, but without the team, the tools, or the training.
So we built all three — a complete training program, a proven template library, and a done-for-you preconstruction service — and put them under one roof.
Engage us per project on a fixed fee. You stay in control; we do the heavy lifting.
Accurate, division-by-division takeoffs from your drawings — concrete, earthwork, structural, MEP, and finishes.
Conceptual, schematic, DD, GMP, or hard-bid estimates with clear assumptions and a transparent markup breakdown.
Sub solicitation, bid leveling, and a clarifications & qualifications package so your number holds up.
A second set of expert eyes on the documents to flag conflicts and value-engineering opportunities early.
A clean, owner-facing proposal package you can submit with confidence.
Hit a busy stretch? Use us as your on-call estimating bench without adding payroll.
Upload drawings + a project description on our intake form.
We send a fixed-fee proposal and preconstruction services agreement within 2 business days.
You approve and sign; we begin the takeoff and estimate.
You receive the bid-ready package on the agreed date.
