General Contracting

• Bid and buyout. Assembling qualified subcontractor coverage across every trade, and comparing bids on real scope rather than headline price.
• Schedule management. A working construction schedule maintained against the contract milestones, with the critical path identified and communicated.
• Site safety. Site-specific safety planning and enforcement, which carries additional weight on school and public facility sites.
• Quality control. Inspection and verification against the contract documents, with issues raised in writing while they are still correctable.
• Submittals, RFIs and change management. Documentation kept current so that questions get resolved without stopping work, and so the record is intact at closeout.
• Closeout and turnover. As-builts, warranties, O&M documentation and owner training delivered as a package rather than chased after occupancy.

Where it strains

The method's weakness is that the contractor arrives after every design decision is fixed. Constructability problems in the documents become change orders rather than redlines. Long-lead items cannot be ordered until award. If the bid market has moved since the estimate was prepared, the owner discovers it at bid opening.

Owners who have been burned this way often move to construction management at-risk or design-build on their next project, or buy pre-construction services separately to get builder input into the documents before they go out.

None of that makes design-bid-build the wrong choice. It makes it a method with a known failure mode, which an owner can plan around. A complete, coordinated design and a current cost estimate remove most of the exposure. An incomplete design sent out to bid to save time reliably costs more than the time it saved.

What happens after award

Once a contract is awarded, the contractor's job is to protect the owner's schedule and the owner's money while the documents are executed as written. In practice that runs on three things: a schedule that is actually maintained rather than filed, submittals and RFIs answered fast enough that work does not stall waiting on a decision, and change management that surfaces cost implications when they arise instead of at closeout.

On school and public facility sites there is a fourth: keeping construction operations separated from the people still using the building. Phasing, access control, dust and noise management and daily coordination with facilities staff are part of the contract, not a courtesy.

Closeout deserves the same attention as the start. As-builts, warranties, operations and maintenance documentation and owner training are assembled as the work proceeds, so the owner takes possession of a complete record rather than chasing paperwork after occupancy.
