Design-build or design-bid-build: picking the right path

The difference between the two delivery methods shows up on a Tuesday afternoon when the framer finds a duct that will not fit above the ceiling. Under one method a phone call settles it before the crew goes home. Under the other, the question travels through two contracts and two companies before anyone is allowed to move a stud. Everything else about design-build versus design-bid-build is a version of that afternoon.

The two sequences, side by side

Design-bid-build runs in three stages that do not overlap. You hire an architect. The architect produces a complete set of drawings. Those drawings go out to several contractors, each prices the same set, and you sign with one of them. The contractor holds one contract with you and the architect holds another, and the two of them owe each other nothing beyond professional courtesy. The appeal is obvious: competing bids on identical documents, and a clean paper trail if a dispute arises.

Design-build collapses the two contracts into one. You sign with a single entity, usually the builder, who either employs the design team or hires the architect and engineers under its own agreement. Design and pricing move together. The builder tells the architect what a detail will cost while the detail is still a sketch, orders long-lead items before the drawings are stamped, and can be pulling permits for the foundation while the interior finishes are still being chosen.

What each method does to the opening date

This is where we spend most of our attention, because the date is what an owner actually lives with. Design-bid-build has a built-in pause: the drawings must be finished before bidding starts, bidding takes weeks, and if the numbers come back high the drawings go back to the architect for a redesign that repeats the cycle. Design-build removes that pause. The tradeoff is that you are trusting one company to police its own design against its own price, and you have fewer outside numbers to check it against.

Where a fixed-design bid still wins

Public work usually requires competitive bids on complete documents, and some lenders and institutional owners prefer it too. A project with a settled program and no open questions, a repeat prototype for a retail brand for example, gets little from early builder input and benefits from three sharp prices on the same drawings. Design-bid-build also suits an owner who already has an architect they trust and wants that architect answering to them rather than to the contractor.

A third path: the builder in the room early

Many of our projects run as a hybrid. The owner keeps an independent architect, we join during schematic design under a pre-construction agreement, and we price each design package as it develops. The owner gets an independent set of drawings and a builder who has already checked constructability, lead times and cost before the set goes final. When the documents are done there is no surprise number, and the schedule already reflects a real crew plan. Our own crews for framing, drywall, millwork, paint, tile and concrete let us price those trades from experience rather than from a sub's quote we have not seen yet.

Deciding for your project

Ask four questions. Is a competitive bid on finished drawings required by your funding or your board. Do you have an architect you want to keep independent. How much of the program is still undecided. And how much does the opening date matter compared with the last few percent of price. A tight date with open scope points toward design-build or the hybrid. A settled program and a bid requirement points toward design-bid-build.

Whichever contract structure you choose, a principal of our company is on your site running the job and is the person you call. Send over your drawings, or the napkin sketch if that is what you have, along with the date you need to open, and we will tell you which path gets you there.
