Estimates built on
quantities, not guesses.

Every line item carries a measured quantity, a documented unit cost source, and a confidence flag. We build estimates that survive bid day, owner audits, and value engineering sessions — from concept through GMP.

E.03
GMP & Hard Bid Estimates
Full quantity takeoffs across all CSI 16 & 50 divisions from construction documents. Unit-priced with current regional data, crew rates, and equipment costs. Class 1 accuracy.
Class 1±2–3%Bid-ready
E.04
Change Order Pricing & Audits
Independent pricing of proposed change orders. Audit contractor-submitted COs for reasonableness, markup compliance, and scope accuracy.
Owner-sideAudit
E.05
Value Engineering Studies
Systematic analysis of design alternatives that reduce cost without compromising function, quality, or schedule. Each VE item includes cost delta and risk assessment.

Build a budget estimate in minutes.

Productivity-based labor costing, material unit pricing, and auto-calculated OH&P and contingency. When you need CSI 16 & 50 division takeoffs and bid-ready estimates, we'll build the real one.

§ NOTE

This is a budget-grade utility — it computes labor cost from productivity rates and rolls up unit-priced material. It does not handle the things that make an estimate truly bid-ready.

  • Full CSI MasterFormat takeoffs
  • Subcontractor scoping & leveling
  • Crew-mix labor rates (composite)
  • Regional cost-index calibration
  • Equipment & specialty items
  • Bonding, insurance, escalation
  • Value engineering alternates

Frequently asked

Questions about estimating.

Conceptual estimates from a program or sketch are ±15–25% (Class 4–5). Schematic/DD budgets land at ±5–10% (Class 2–3). Full CD-level hard bid estimates target ±2–3% (Class 1). We document the confidence level and key assumptions.
The construction documents (whatever stage), a scope narrative or program if available, any known budget targets, and the timeline. For conceptual work, a sketch and a conversation are enough.
Both. We deliver in whichever MasterFormat scheme your project requires — traditional 16-division Broadscope or the current 50-division format. We'll match your needs.
A conceptual ROM estimate can be turned in 48 hours. Full detailed estimates take 5–10 business days depending on size and complexity.
Yes — we perform independent estimate reviews for owners and developers. We review methodology, spot-check quantities, validate unit costs, and flag scope gaps.
