Cost planning · Aagento Team
From design inputs to a reviewable infrastructure estimate
A workflow guide to quantities, rates and the assumptions behind an estimate.
Define what the estimate is for
An early planning estimate, a DPR cost exercise and a tender estimate may have different scopes. Start by recording the purpose, project boundaries and information available at that stage. Make exclusions visible so reviewers understand what the estimate covers.
Keep quantities connected to their source
Document the drawing, model or schedule behind each quantity. Check units and identify any provisional values. When a design revision changes the scope, knowing the source of each quantity helps the team find the estimate items that may need updating.
Record the basis of the rates
A rate needs context: its source, location, date and any project assumptions. Where a schedule of rates is used, record the relevant reference and adjustments. Review lead distances and other cost assumptions with the people who understand the project conditions.
Check the connections before issuing
Review the BoQ alongside its design basis and report summaries. Look for scope gaps, inconsistent units and quantities copied from earlier revisions. Keep a record of the review and resolve questions before using the estimate for the intended decision.
Discuss your estimating workflow with Aagento
Aagento’s cost estimation module describes quantity takeoff, BoQ generation, rate analysis and SOR integration. Bring a sample quantity sheet, rate reference and project brief to a demo so the discussion can focus on your actual estimating process.
