Design development is one of the most important stages for cost control. At this point, the project is becoming more defined, but there is still time to influence scope, materials, systems, and budget decisions.
The challenge is that many pricing issues begin before anyone is in the field. Incomplete drawings, unclear specifications, rushed bid schedules, late addenda, and inconsistent vendor information can all create exposure. Cost control during this stage prevents the budget from drifting without visibility.
A strong process starts with slowing down enough to review the documents correctly. The estimator should confirm the drawing set, review the specifications, identify addenda, separate base scope from alternates, and document assumptions before pricing is finalized.
Key items to review include:
- Scope shown on the drawings and required by the specifications
- Exclusions, qualifications, alternates, and allowances
- Labor, material, equipment, and productivity assumptions
- Procurement timing, quote validity, and lead-time concerns
- Risks that should be clarified before bid submission
For subcontractors, the goal is not simply to submit another number. The goal is to submit a number that is complete, understandable, and defendable. Quantity updates, assumption tracking, and value options are key.
TBT Estimating Services helps subcontractors strengthen their estimating process through takeoff, quantity survey, ROM and should-cost estimates, bid leveling, change order support, and preconstruction review.
