Design-Build vs. Design-Bid-Build: Which Project Delivery Method Is Right for You?
By Mike Deihl, Project Executive – When planning a construction project, one of the first decisions you’ll make is selecting the right project delivery method. Two of the common approaches are design-build and design-bid-build. These delivery methods differ significantly in how teams are organized, how risks are managed, and when critical decisions are made.
What Is Design-Build Construction?
In simple terms, design-build is the delivery method that integrates the design and construction under one contract, early in the process to create one accountable team, while design-bid-build separates design and construction into distinct phases and contracts.
Under the design build scenario, the contractor and design team are on board early, together and with a set fee and known target budget. Rather than hiring an architect to complete the design and then separately selecting a contractor, the owner works with one integrated team responsible for both design and construction. Architects, engineers, estimators, project managers, and construction professionals collaborate from the start, aligning project goals, budget, schedule, and constructability throughout the process.
The defining characteristic of design-build is its single point of responsibility. One team owns both design and construction obligations, reducing the potential for disputes, change orders, budget creep and streamlining communication.
Because the designer and builder are integrated from the beginning, design-build allows for overlapping design, procurement, and construction activities, making it one of the most efficient project delivery methods available today.
Design-build works especially well when an owner can clearly define:
- Project goals and performance criteria
- Budget expectations
- Schedule requirements
- Design standards
- Approval processes and decision milestones
At Holland Construction, design-build projects leverage early preconstruction services such as cost modeling to create a target budget, constructability reviews, BIM coordination, Target Value Design methods, and ongoing collaboration to help owners make informed decisions before drawings are finalized.
What Is Design-Bid-Build?
Design-bid-build is the traditional project delivery method that has been used throughout the construction industry for decades.
The process follows three distinct phases:
Design
The owner hires an architect or engineer to develop complete construction documents.
Bid
Once the design is completed, contractors submit competitive bids based on the plans and specifications.
Build
The project is awarded, typically to the lowest responsible bidder, and construction begins.
Design-bid-build works best for simple, fully defined projects with limited unknowns.
The method offers several advantages:
- Familiar procurement process
- Open public competition
- Clear separation of design and construction responsibilities
However, it also has limitations. Since builder input is largely absent during design, constructability concerns, budget issues, and scope gaps may not be identified until bidding is complete. When pricing exceeds expectations, owners often face difficult decisions involving redesign, deductive alternates, schedule impacts, or change orders.
For projects where schedule is not the primary driver and the scope is well-defined, design-bid-build can remain an effective delivery strategy.
Key Differences Between Design-Build and Design-Bid-Build
The table below highlights the most important differences between these two project delivery methods.
| Criteria | Design-Build | Design-Bid-Build |
| Contract Structure | One contract for design and construction | Separate contracts for designer and contractor |
| Team Integration | Designer and builder integrated from the start | Contractor joins after design completion |
| Selection Method | Best-value evaluation based on qualifications, technical approach, and cost | Typically awarded to the lowest responsible bidder |
| Project Speed | Design, procurement, and construction can overlap | Sequential process |
| Cost Certainty | Continuous budgeting during design | Final pricing determined after design is complete |
| Owner Risk | Single point of design and construction responsibility | Owner bears many design gaps and constructability risks |
| Communication | Unified team and streamlined decision-making | Multiple parties and communication channels |
| Change Orders | Issues identified earlier, change orders limited to owner requests for changes | Problems frequently discovered after bidding or during construction |
| Collaboration | High collaboration among all stakeholders | Limited or no contractor input during design |
| Best Fit | Complex projects, aggressive schedules, clear owner criteria | Simple projects with complete documents and limited unknowns |
The biggest distinction between design-build vs design-bid-build comes down to integration. Design-build creates one collaborative team accountable for project success, while design-bid-build separates responsibilities between designers and builders.
Advantages of Design-Build
As owners increasingly look for ways to reduce risk, accelerate schedules, and improve outcomes, design-build continues to gain popularity across commercial, healthcare, education, municipal, and industrial markets.
Faster Project Delivery
One of the greatest advantages of design-build is speed.
Because design, procurement, and construction activities can overlap, projects frequently move from concept to completion significantly faster than traditional delivery methods. Industry studies commonly show design-build projects finishing 20-30% faster than comparable design-bid-build projects.
For organizations facing occupancy deadlines, funding constraints, enrollment growth, or market opportunities, accelerated delivery can create substantial value. After all, costs go up over time.
Single Point of Accountability
In a traditional project, disagreements can arise over whether an issue is a design problem or a construction problem.
With design-build, one entity is responsible for both.
Owners benefit from:
- Clear accountability
- Faster problem resolution
- Simplified communication
- Reduced administrative burden
The integrated approach substantially reduces the finger-pointing that can occur when design and construction responsibilities are divided.
Earlier Cost Certainty
Under design-bid-build, actual market pricing is typically not known until the project is fully designed and bid.
If bids come back over budget, owners may need to redesign portions of the project or reduce scope, which results in costly redesign fees.
With design-build delivery method, estimating occurs throughout the design process. Continuous cost evaluation allows the team to align design decisions with project budgets before documents are finalized, reducing or eliminating rework and extra costs.
Better Collaboration
Design-build requires collaboration from day one.
Architects, engineers, estimators, trade partners, and construction professionals work together to evaluate options, identify risks, improve constructability, and optimize value.
Reduced Change Orders
Constructability concerns are identified much earlier.
This proactive approach reduces the likelihood of:
- Scope gaps
- Design conflicts
- Late-stage redesign
- Costly change orders
- Schedule disruptions
The result is a smoother project experience and greater confidence for owners.
How to Choose the Right Delivery Method for Your Project
Every project is unique, and the best delivery method depends on your priorities.
Design-Build May Be Right If:
- Schedule is critical.
- You want one accountable partner.
- Early budget certainty is important.
- The project involves significant complexity or coordination.
- You can clearly define project goals, standards, and performance expectations.
- You want a collaborative, integrated approach.
Design-Bid-Build May Be Right If:
- The project scope is simple and fully defined.
- Design control is the highest priority.
- Public bidding requirements govern procurement.
- The owner has experience managing multiple contracts.
- Schedule acceleration is not a primary concern.
At Holland Construction, our preconstruction team helps owners evaluate delivery options based on project goals, risk tolerance, schedule requirements, and budget expectations. Whether the best solution is design-build, construction management, or another delivery method, early engagement of the pertinent team members creates a strong foundation for success.
Frequently Asked Questions
Is design-build more expensive than design-bid-build?
No.
While design-bid-build often focuses on achieving the lowest initial bid, total project value involves much more than first cost. Here are some examples:
- Anything not in the contract documents becomes subject to change and extra cost.
- All savings on the construction side are realized by the contractor. Very rarely are there design-bid-build scenarios that provide savings to the owner. Many times the owner will not know the actual cost.
- With Design-Build, many times the contract is a cost plus fee with all savings or a portion thereof returned to the owner. It is a very transparent delivery method.
- Design-build can reduce costs associated with schedule delays, redesign efforts, constructability issues, and change orders. Early collaboration often creates opportunities to optimize value before construction begins.
What types of projects are best suited for design-build?
Design-build is particularly effective for:
- Schools and higher education facilities
- Healthcare facilities
- Manufacturing and industrial projects
- Commercial developments
- Municipal buildings
- Projects with aggressive schedules
- Projects requiring significant stakeholder coordination
Any project where speed, accountability, collaboration, and cost certainty are important can benefit from design-build.
Can I still have input on the design in a design-build project?
Absolutely.
Successful design-build projects depend on owner engagement. Owners establish project goals, performance requirements, standards, and approval processes early in the process and remain involved in key decisions throughout design development and construction.
