Outsourced estimating for US general contractors and subcontractors — accurate quantity takeoffs and bid-ready estimates across every CSI trade, delivered in 24 to 48 hours.
Preconly provides outsourced construction cost estimating services to general contractors, subcontractors, and developers across the United States. Whether you need a single-trade takeoff or a complete bid-ready estimate spanning every CSI division, our estimators deliver accurate, well-documented numbers in your format — usually within 24 to 48 hours.
Every estimate we produce is built to be submission-ready. You receive detailed quantity takeoffs with material, labor, and equipment breakdowns; pricing adjusted to your project's zip code; clearly documented assumptions, inclusions, and exclusions; and a clean bid summary ready for your markup. We work in the tools you already trust — PlanSwift, Bluebeam Revu, On-Screen Takeoff, and STACK — with pricing aligned to RSMeans and current local market data.
Our team estimates the full range of construction scopes: sitework and earthwork, concrete and masonry, structural and miscellaneous metals, carpentry, roofing and waterproofing, doors and glazing, drywall and finishes, flooring, plumbing, HVAC, electrical and low-voltage, and exterior improvements. We handle residential, multifamily, commercial, retail, industrial, medical, and government projects — new construction, renovations, and tenant improvements alike.
Hiring an in-house estimator costs upward of $80,000 a year plus benefits and software licenses — a heavy fixed cost that sits idle between bid cycles. Outsourcing your estimating converts that fixed cost into a flexible, per-project or monthly expense. You bid more projects during busy seasons without adding payroll, and you pay nothing for capacity you don't use. Because our production runs while most US offices are closed, plans sent at the end of your day are often in progress by the next morning.
The best way to evaluate an estimating partner is on real work. Send us a scope you have already bid — one where you know the right number — and we'll produce a sample so you can judge our accuracy, format, and turnaround before committing to anything larger.
