A Preconstruction Partner for BIM, CAD, Estimating, Takeoff, and Documentation
Optimar Precon works as an extended preconstruction support team for construction businesses that need reliable technical capacity, organised deliverables, and dependable project communication. Our work supports early-stage planning, bid preparation, drawing production, model coordination, quantity measurement, and construction documentation.
Instead of treating BIM, CAD, estimating, and takeoff as disconnected tasks, we support them as connected preconstruction workflows. This helps clients move from drawings and models to coordinated documents, clearer quantities, and stronger project decisions.
