The delivery method chosen for a commercial project determines how its design and construction are contracted, sequenced, and held accountable. That choice shapes the schedule, the certainty of cost, and the degree of risk an owner assumes. Design-build and design-bid-build represent two distinct approaches to the same objective, and the difference between them is consequential.
Dakota Contractors delivers commercial projects across Metro Atlanta under both models.
Design-bid-build: the traditional model
Design-bid-build is the conventional delivery method and proceeds in three sequential stages. The owner first engages an architect to complete the design. The completed documents are then issued for a competitive bid. The owner awards a construction contract to a selected contractor, and construction begins.
This model holds design and construction under separate contracts with separate accountability. The owner manages two distinct relationships and serves as the intermediary between them. Its principal advantage is competitive pricing on a fully defined scope, since contractors bid against complete documents. Its principal limitations are sequential timing and divided responsibility. Construction cannot begin until design is complete, and when conflicts arise between the drawings and the field, the design and construction parties are positioned against one another rather than aligned.
Design-build: the integrated model
Design-build consolidates design and construction under a single contract with a single accountable entity. The owner engages one team responsible for the project from concept through completion. Design and construction proceed in coordination rather than in sequence.
This integration is the source of the model's advantages. Construction expertise informs the design as it develops, which keeps the documents buildable and the budget realistic. Phases overlap, which compresses the overall schedule. Accountability is unified, which removes the gaps where errors and disputes accumulate between separate parties. A single team carries responsibility for the outcome.
Dakota's Design-Build delivery brings design and construction into one accountable relationship, supported by the preconstruction discipline that makes the model perform.
How the two methods compare
Accountability
Design-bid-build divides accountability between the designer and the contractor, with the owner mediating between them. Design-build consolidates it under one entity responsible for both. When a question arises in the field, an integrated team resolves it internally rather than negotiating across contracts.
Schedule
Design-bid-build is sequential. Construction begins only after design and bidding conclude. Design-build overlaps design and construction, allowing early work to proceed while later design develops. For projects where schedule is a priority, this compression is the model's most tangible benefit.
Cost certainty
Design-bid-build establishes cost through a competitive bid after the design is complete, which means the true cost is unknown until late in the process. Design-build introduces cost input early, during Preconstruction, where the budget is developed alongside the design and pressure-tested before commitment. Cost certainty arrives sooner when the project can still be adjusted to meet it.
Risk
Design-bid-build places the owner between two parties and exposes them to the conflicts that arise when drawings meet field conditions. Design-build assigns that risk to the single entity responsible for both, which absorbs the coordination rather than passing it to the owner.
Change orders
Conflicts between design and construction are a primary source of change orders under the traditional model, since the parties who produced the design and the parties who are building it are separate. Integrated delivery reduces this exposure by evaluating constructability as the design develops, before the documents are finalized.
Which method fits the project
Design-bid-build remains appropriate where a project is fully defined, where competitive bidding on complete documents is a priority, and where schedule pressure is limited. Design-build is the stronger fit when schedule matters, when cost certainty is needed early, and when unified accountability reduces the owner's burden. For commercial interiors, tenant improvements, and renovations on a defined timeline, integrated delivery consistently produces a more reliable outcome.
The determining factor is rarely the method in the abstract. It is the strength of the team executing it. An integrated team is only as effective as its preconstruction discipline and its command of field construction.
The Dakota approach
Dakota delivers design-build with the preconstruction rigor that the model depends on. Cost and constructability are evaluated as the design develops, existing conditions are captured precisely, and the budget is defined before commitment. Construction is executed under active Construction Management by a team that brings the attention of a small contractor and the resources of a large one.
The Selig family has built in Atlanta for over 105 years, and Dakota has delivered commercial projects across Metro Atlanta since 1998, using both delivery models, matched to each project's requirements.
