Government Construction Estimating
Prepare public-project estimating inputs: bid schedules, alternates, wage documents, quantity units and scope qualifications.
Public-project estimating begins with the actual solicitation and bid schedule. The construction drawings define physical work, while the procurement documents explain how the owner expects that work to be priced and presented. Keep those two sources connected throughout the takeoff.
Register the procurement documents
Send the invitation to bid, current drawings, specifications, addenda, bid forms and scope clarifications. Identify the project owner and location rather than assuming a federal, state or municipal package follows the same requirements. Record the relevant revision and the bid deadline.
Where the documents specify a wage determination or other labor basis, provide that exact document and applicable project information for the pricing scope. This page does not determine legal applicability, certify compliance or replace advice from the responsible contracting and project professionals.
Reconcile quantities to the owner's bid schedule
Separate lump-sum work, unit-price items, alternates and provisional quantities. Match each measured scope to its bid item without silently changing the owner's unit of measure. A drawing quantity and a bid-payment quantity may use different definitions; document the basis and unresolved differences.
For civil packages, compare earthwork, excavation and utility scope so shared trenching or restoration is assigned consistently. Separate temporary measures and removals from permanent construction.
Carry qualifications visibly
Identify owner-supplied materials, work by other packages and testing or inspection responsibilities from the documents. List missing drawing details and inconsistent schedules as clarification items. Avoid converting an unresolved requirement into an unsupported measured quantity.
For a priced estimate, agree how mobilization, general conditions, bonds, insurance, overhead and other bid-level items are handled. These are scope decisions; they should not automatically be copied as one percentage from an unrelated project.
Manage addenda and alternatives
Maintain a revision log showing which sheets and specifications changed. Show additions and deductions separately where the owner requests alternate pricing. Confirm whether a later addendum requires a limited quantity update or a broader estimate revision, including the fee and delivery date.
A practical deliverable
Request a drawing-referenced quantity schedule, an estimate basis when pricing is included, and a list of qualifications tied to the solicitation. Use the pre-bid checklist to organize review tasks; completing it does not establish procurement compliance.
Does a quantity takeoff establish a compliant public bid?
No. The contractor must review the solicitation, required forms and final bid with the responsible professionals. A takeoff supports the quantity and scope review.
Can an owner schedule be retained?
Provide the actual schedule and identify the columns or units that must remain unchanged. Confirm the agreed output before measurement begins.
Discuss the public-project package and review quote inclusions.
