To avert field surprises, I commissioned a professional Constructability review early in design. Their engineers ran clash‑detection on my BIM model, flagged every joist‑duct and pipe‑beam conflict, and delivered red‑lined plans with sequencing optimizations. They also verified all clearances against code and provided a detailed coordination log. By folding their findings into my permit set, inspections sailed through, subcontractors followed a clash‑free blueprint, and the build progressed on schedule saving weeks of downtime and thousands in change‑order fees.
