Delegated administration vs. fixed-price construction: which approach fits your project?

1. What is delegated administration?

Under delegated administration, the builder or construction manager executes the project on behalf of the owner. Actual costs for materials, labor, equipment and subcontractors are documented and controlled, while the manager receives the agreed fee or percentage. This model requires disciplined records, a baseline budget and clear approval rules.

2. What does fixed-price construction mean?

Under a fixed-price or lump-sum arrangement, the contractor undertakes a defined scope for an agreed amount, subject to the quantities, specifications, assumptions and exclusions in the contract. It works best when the project is sufficiently defined; otherwise, gaps and changes can become extras or disputes.

3. Transparency and owner control

Delegated administration generally gives the owner more visibility into purchases and actual costs, but it also requires more involvement and follow-up. A fixed-price contract can simplify owner administration, but the proposal must clearly state what is included and how changes, additional quantities and unforeseen conditions are handled.

4. Who carries cost-variation risk?

Risk allocation should be written into the contract. Under delegated administration the owner is usually more exposed to actual cost variation, while under a fixed-price contract the contractor may carry part of that risk within the agreed scope. Neither model eliminates the effect of owner changes, unforeseen conditions or incomplete information.

5. When can each model make sense?

Delegated administration can work well when the project may evolve during construction, cost transparency is important or the owner wants to participate in procurement decisions. Fixed-price construction can be attractive when drawings, quantities and specifications are well defined and greater contractual predictability is desired.

6. What to review before signing

The contract matters more than the label: scope, baseline budget, fees, payment terms, procurement, advance or working-cash management, approvals, reports, extras, schedule, warranties and closeout. An ambiguous contract can create problems under either model.
