What's the difference between an owner's estimate and a GC's bid?

An owner's estimate is prepared before bidding to establish a budget and evaluate bids when they come in. It should be independent of contractor pricing, documented to the source, and carry an accuracy range. A GC's bid is a firm offer for a specific scope.

How do estimators handle escalation in multi-year projects?

Apply a published escalation index (ENR, Turner, or regional CCI) from the estimate date to the midpoint of construction. Document the escalation rate and source as a line item so owners can update it as the schedule changes.

Construction Bid Templates for Estimators

Estimators preparing owner's estimates or independent cost reviews need a different template than a GC bidding on a project. The purpose isn't to win a job — it's to give an owner or lender a defensible, documented cost number that holds up to scrutiny. That requires a different level of documentation, source citation, and accuracy disclosure than a contractor's bid.

Structuring bid templates for owner's estimates and peer reviews

An estimator's construction bid template should document: the estimate purpose and intended use; the design documents reviewed (drawings, specs, addenda) with revision dates; the estimate methodology (unit cost, assemblies, or detailed takeoff); sources for unit cost data (RSMeans, Gordian, subcontractor quotes, or historical projects); a complete line-item estimate by CSI division or system; stated exclusions; and an accuracy range with justification. This is the professional deliverable standard that architects, lenders, and public agencies expect.

Estimating for owners and peer reviews

State the design documents you reviewed — owners need to know what your estimate is based on
Cite your unit cost database version and date — costs change and sources matter
Use CSI MasterFormat division structure for public and institutional projects
Flag any design gaps that required assumptions larger than 5% of the line item
Provide a cost range, not a single number — owners who understand uncertainty make better decisions

Typical projects

Public agency budget estimates
Independent peer cost reviews
Lender or investor feasibility estimates
Program-level capital planning
Design-phase value engineering

Pricing context

Estimators hired for independent reviews or owner's estimates bill $100–$175/hr. Value comes from accuracy and documentation, not speed. A well-documented estimate that prevents a $500,000 change order is worth significantly more than the estimate fee.
