You’re ready to expand your business with a new facility. You’ve heard terms like “design-build,” “construction management,” and “design-bid-build” thrown around, but what do they actually mean, and which approach really saves you time and money?
If you’re like most commercial property owners, the construction process can feel overwhelming. Multiple contracts, coordination between separate design and construction teams, and finger-pointing when something goes wrong.
There’s a better way.
What Is Design-Build Construction?
Design-build is a construction delivery method where a single entity — the design-build contractor — handles both the design and construction phases of your project.
Instead of hiring an architect separately from your general contractor, you work with one team that manages everything from initial concepts through project completion. This integrated approach streamlines communication, reduces risk, and often delivers projects faster and within budget.
For commercial projects in Maine, design-build has become increasingly popular among business owners, developers, and institutional clients who value efficiency and accountability.
How Design-Build Differs from Traditional Construction Methods
Understanding your options helps you make the best decision for your project. Here’s how the three main construction delivery methods compare:
Design-Bid-Build (Traditional Method)
- Owner hires architect to complete design
- Finished plans go out to bid to general contractors
- Owner selects contractor based on bids
- Construction begins after design is 100% complete
- Owner manages relationship between designer and builder
Construction Management
- Owner hires construction manager as advisor
- Construction manager provides input during design
- Work is bid out to multiple subcontractors
- Construction manager coordinates and depending on contract type, may or may not guarantee price
- Owner maintains separate contracts with designer and CM
Design-Build (Integrated Method)
- Single contract covers both design and construction
- Designer and builder collaborate from day one
- Construction can begin before design is fully complete (fast-track)
- One entity responsible for budget, schedule, and quality
- Streamlined communication and decision-making
The fundamental difference? In design-build, your contractor and design team work together from the start, not after plans are finalized. This collaboration catches potential issues early, when they’re easier and less expensive to solve.
The Design-Build Process: Step by Step
While every project is unique, the design-build process typically follows these phases:
Phase 1: Initial Consultation and Programming
Your design-build team meets with you to understand your needs, budget, timeline, and vision. This programming phase establishes project goals and identifies any site constraints or regulatory requirements.
What happens: Stakeholder interviews, site analysis, preliminary budget discussions, feasibility studies
Timeline: 2-4 weeks for most projects
Phase 2: Conceptual Design and Budget Development
The design team creates initial concepts while the construction team provides real-time cost feedback. This simultaneous approach means you know whether your vision fits your budget before investing heavily in detailed plans.
What happens: Schematic drawings, preliminary specifications, order-of-magnitude estimates, value engineering discussions
Timeline: 3-6 weeks depending on project complexity
Phase 3: Design Development and Guaranteed Maximum Price
As the design becomes more refined, the construction team provides increasingly accurate cost estimates. Many design-build contracts include a Guaranteed Maximum Price (GMP) at this stage, giving you budget certainty while design continues.
What happens: Detailed drawings advance to 50-70% completion, material selections, systems design, firm pricing from key subcontractors
Timeline: 4-8 weeks
Phase 4: Final Design and Permitting
The design team completes construction documents while the project team handles permitting and regulatory approvals. Because the builder has been involved throughout, the final plans are constructible and reflect real-world building methods.
What happens: 100% construction documents, permit applications, final material specifications, subcontractor selection
Timeline: 4-8 weeks (varies by jurisdiction)
Phase 5: Construction
Here’s where the design-build advantage becomes most apparent. Because your builder helped create the plans, construction proceeds smoothly with fewer change orders and surprises. The design team remains available to address field questions immediately.
What happens: Site preparation, building construction, systems installation, regular owner meetings, quality control inspections
Timeline: Varies widely by project scope
Phase 6: Closeout and Warranty
The design-build team coordinates final inspections, trains your staff on building systems, and ensures all documentation is complete. Your single point of contact continues through the warranty period.
What happens: Punch list completion, final inspections, owner training, as-built drawings, warranty documentation
Timeline: 2-4 weeks after substantial completion
Bringing the Blueprints to Life – The Real Advantages of Design-Build
Faster Project Delivery
Fast-track scheduling allows construction to begin on site and foundations work while interior design details are still being finalized. This overlap can reduce total project duration compared to traditional methods.
For businesses and organizations, this means getting into your new facility sooner and generating revenue faster. For institutional clients like schools, it means less disruption to operations.
Cost Certainty and Control
With traditional design-bid-build, you don’t know the actual construction cost until after investing significant money in completed plans. If bids come in over budget, you face expensive redesigns or value engineering that may compromise your vision.
Design-build solves this. Continuous cost estimating throughout design means budget issues surface early, when solutions are straightforward. The Guaranteed Maximum Price protects you from cost overruns due to design changes or unforeseen conditions.
Single Point of Accountability
When problems arise on traditional projects, you might hear “that’s not how it was designed” from your builder or “that’s not what we intended” from your architect.
Who’s responsible? Who fixes it?
Design-build eliminates this finger-pointing. One team owns both design and construction, creating accountability that benefits you throughout the project and during the warranty period.
Reduced Change Orders
Because builders contribute constructability input during design, plans reflect how buildings actually get built. Details that might cause field problems get resolved on paper, not through expensive change orders during construction.
In our experience, design-build projects typically see significantly fewer change orders than traditional delivery methods.
Enhanced Collaboration and Innovation
When designers and builders work together from day one, creative problem-solving flourishes. The construction team might suggest alternative materials that achieve your design goals at lower cost. The design team can refine details knowing the builder’s capabilities and preferred methods.
This collaborative approach is exactly why Ganneston offers design-build services — to give clients a single, trusted partner from concept through completion. With over 60 years of construction experience, we can provide valuable input on constructability, cost, and schedule from the very first meeting.
When Design-Build Makes Sense (and When It Doesn’t)
Design-Build Works Best For:
- Projects with tight timelines. Fast-track scheduling delivers buildings months sooner than traditional methods.
- Budgets requiring early cost certainty. The Guaranteed Maximum Price approach provides financial predictability.
- Complex projects benefiting from collaboration. Technical buildings, renovations, or projects with challenging sites gain from integrated problem-solving.
- Owners wanting simplified project management. One contract, one point of contact, one responsible party.
- Projects where team chemistry matters. You select your design-build partner based on qualifications and fit, not just lowest bid.
When Traditional Methods Might Be Better:
- Public projects requiring competitive bidding. Some government agencies must use design-bid-build for legal or procedural reasons (though many are adopting design-build).
- Projects where design is complete and unchanging. If you already have finished plans and specifications, traditional bidding might make sense.
- Owners with in-house design expertise. Some large organizations prefer to control design entirely and hire only construction services.
- Situations requiring design-builder separation. Occasionally, owners want complete independence between design and construction for checks and balances.
At Ganneston, we’re transparent about which delivery method serves your interests best. Our commitment to completing projects safely, on-time, and on-budget aligns perfectly with the design-build philosophy of accountability. We also offer design-bid-build and construction management services when those approaches better fit your needs.
What to Look for in a Design-Build Contractor
Not all design-build firms are created equal. Here’s what distinguishes qualified design-build contractors:
#1 Demonstrated Experience
Look for contractors with a proven track record of successful design-build projects similar to yours in scope and complexity.
#2 In-house design capabilities or strong design partnerships
Some firms employ staff architects and engineers. Others have long-standing relationships with design firms. Either model works if collaboration is genuine.
#3 Bonding and insurance capacity
Design-build projects require robust financial backing. Verify the contractor can bond your project size and carries appropriate liability coverage.
#4 Transparent processes
Reputable design-build contractors clearly explain how cost estimating, value engineering, and change management work. You should understand how decisions get made and what approvals you’ll provide.
#5 Strong subcontractor relationships
Much of your project will be built by specialty contractors. Your design-build firm should have established relationships with reliable subcontractors who provide competitive pricing.
#6 Communication commitment
The primary benefit of design-build is streamlined communication. Your contractor should establish clear meeting schedules, reporting protocols, and decision-making processes.
#7 Regional expertise
Local knowledge matters. Contractors familiar with Maine building codes, permitting processes, climate considerations, and local subcontractor availability deliver better results than firms from outside the region.
Frequently Asked Questions About Design-Build
How much does design-build cost compared to traditional construction?
Total project costs are typically comparable or lower with design-build. While design fees might be similar, you often save on construction costs through better coordination, fewer change orders, and value engineering. Time savings also reduce interim financing costs and get you into your facility faster.
Do I lose design control with design-build?
No. You remain involved in all design decisions. The difference is you have construction expertise at the table during design, which often improves outcomes rather than limiting them.
How do I compare design-build proposals if they’re not all bidding the same plans?
Design-build selection emphasizes qualifications, approach, team chemistry, and preliminary pricing rather than lowest bid on identical plans. Request detailed proposals showing team experience, project approach, preliminary budgets, and sample schedules.
Can design-build work for renovations or just new construction?
Design-build works excellently for renovations, especially complex projects where existing conditions might require design adjustments during construction. The integrated team can adapt quickly to unexpected site conditions.
What happens if I’m not satisfied with the design?
Reputable design-build contracts include design phase approvals. You sign off at key milestones before moving forward. If you’re unsatisfied, you can pause, request revisions, or in some cases, terminate before construction begins.
