Owner education for clearer commercial construction decisions.
Decision sequence
How an owner moves through design-build
Define performance
State the business outcome, functional needs, quality standard, schedule, budget, and required approvals before procurement.
Select the team
Evaluate qualifications, key people, relevant work, approach, commercial terms, and the method for developing price.
Develop scope and cost
Design, estimating, constructability, procurement, and owner decisions advance together through documented milestones.
Authorize construction
The team confirms the agreed documents, price basis, allowances, contingencies, schedule, and unresolved risks.
Verify the result
Commissioning, training, record documents, warranties, and closeout are managed against the owner's requirements.
Decision table
Traditional and progressive design-build
| Factor | Traditional approach | Progressive approach |
|---|---|---|
| Selection | May include design concept and price | Often qualifications and approach first |
| Price timing | Can be established during procurement | Developed collaboratively after selection |
| Design maturity at selection | Varies, sometimes more defined | Often early |
| Owner off-ramp | Contract specific | Usually addressed before final price commitment |
Signal check
Where integrated delivery earns its value
Strong conditions
Schedule benefits from overlapping work
Long-lead items need early attention
The owner can define performance needs
The team offers transparent cost development
Design and field leaders work as one unit
Conditions to resolve
The owner expects design control without defining approval rights
Selection relies on price alone
Scope is vague but certainty is promised
Cost reporting is opaque
The agreement does not address design responsibility

Questions, answered
Design-build, clarified
Does the owner lose all design control?+
No. The agreement should define owner requirements, review points, approvals, performance criteria, and the design-builder's professional responsibilities.
Is design-build always faster?+
It can shorten delivery by overlapping activities, but actual performance depends on procurement, approvals, decision speed, project conditions, and team capability.
