Scope and inputs to reconcile
Define the affected drawing sheets, RFI or instruction, changed systems and revision dates. Identify completed work, unused materials, credits and replacement work separately.
Workflow and checks
Compare the two issued sets, mark additions and deletions, and reconcile vendor quotations with quantities already purchased. Use the contract’s agreed pricing rules where supplied; show assumptions when terms are unresolved.
What the output should show
Request a delta quantity schedule, cost backup, drawing references, credit/addition totals and a record of exclusions. Schedule impact should be supported separately from the direct-cost calculation.
Exclusions and unresolved decisions
An estimate does not establish entitlement, approval of a claim or a guaranteed recovery. Delay analysis and legal interpretation are separate professional tasks.
Documents to share for a quote
Provide the original bid scope, baseline and revised drawings, change instruction, relevant pricing terms and purchase/time records. State the reviewer’s required format and response deadline.
