Construction Cost Estimating Services

Construction cost estimating services, built to bid.

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.

What our construction estimating service includes

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.

Estimating across all CSI trades

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.

Why contractors outsource estimating to Preconly

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.
