The Faster Way to Build
Most construction projects take longer and cost more than planned. You’ve probably heard this. You may have lived it.
The traditional model is part of the problem. You hire an architect. They design the project. You take that design to a contractor, who finds problems the architect didn’t anticipate. Change orders start stacking up. Timelines slip. Everyone points at someone else.
Design-build construction fixes this at the source. One team. One contract. One point of accountability from concept through completion.
It’s not a new idea, but it’s become the dominant delivery method for commercial construction owners who’ve been burned by the alternative.
What Is Design-Build Construction?
Design-build is a project delivery method where a single entity handles both the design and the construction of a project under one contract.
That single entity can be a general contractor with in-house design capabilities, an architecture firm that leads construction, or a specialized design-build firm that integrates both disciplines from day one. What matters is that the owner deals with one team and one agreement covering the entire project scope.
Compare that to the traditional design-bid-build approach:
Design-Bid-Build (Traditional)
- Owner hires architect separately
- Architect produces drawings
- Owner takes drawings to bid
- Contractor is selected, often lowest bid
- Design problems surface during construction
- Disputes and change orders follow
Design-Build
- Owner hires one team covering design and construction
- Design and construction planning happen in parallel
- Conflicts between design and buildability get resolved early
- Budget is set and protected through the process
- One contract, one schedule, one point of contact
The structural difference sounds small. In practice, it changes everything about how a project runs.
Why Design-Build Is Faster
Speed comes from parallel workflows. In a traditional project, construction can’t start until design is fully complete and bids are in. That sequential process can add 6 to 12 months to a project before a single shovel hits the ground.
In design-build, the contractor is involved during design. That means:
- Site preparation and procurement can begin while design details are still being finalized
- The team catches constructability issues at the drawing stage, not after a foundation is poured
- Subcontractors and suppliers are engaged earlier, reducing lead time surprises
- Decision-making stays within one team instead of bouncing between separate firms
According to industry studies, design-build projects are delivered significantly faster than design-bid-build on average. For owners with aggressive timelines, national rollout programs, or opening dates tied to lease agreements, that gap is the difference between a successful project and a missed opportunity.
Parkway Construction’s 5X Build™ Process is built around this principle. By integrating design coordination, procurement, and construction scheduling from the very start, the team has cut project timelines by up to 33% compared to industry averages.

Why Design-Build Costs Less
Cost savings in design-build come from a few directions at once.
- Early Contractor Input Reduces Rework
When a contractor is in the room during design, they flag expensive decisions before they’re locked in. Material choices, structural systems, mechanical layouts, and site logistics are evaluated for cost alongside aesthetics and function. That doesn’t happen in traditional projects where the contractor sees drawings for the first time at bid.
- Fewer Change Orders
Change orders are expensive, both in direct cost and in the schedule disruption they cause. In design-build, the same team that designed the project is building it. Ambiguities get resolved at the design table, not in the field.
- Competitive Pricing Through Value Engineering
A design-build contractor has incentive to find value in the design because cost overruns come out of their own margin. That alignment of interests means the team actively looks for ways to deliver the same result for less without cutting corners on quality.
- Faster Schedule Means Lower Carrying Costs
Every month a project runs long costs the owner money. Loan interest, delayed opening revenue, extended staff overhead, and escalating material costs all add up. A faster delivery reduces all of it.
Parkway Construction backs this with a Price Lock on design-build projects, offering owners cost certainty at the contract stage rather than a final bill full of surprises.
Design-Build vs. Design-Bid-Build
Understanding the key differences between project delivery methods — and why Parkway's integrated approach drives faster, more predictable results.
| Factor | Design-Build | Design-Bid-Build |
|---|---|---|
| Contracts | One Simpler Single unified agreement | Two or more Separate design & construction contracts |
| Accountability | Single point Clear One team owns the outcome | Split between architect / contractor Shared responsibility can blur accountability |
| Schedule | Faster 33% Faster Overlapping phases compress timelines | Slower Sequential phases — design completes before bidding begins |
| Cost Certainty | Higher Guaranteed GMP or fixed price with Parkway's Price Guarantee | Lower Variable Bids can escalate during construction |
| Change Orders | Fewer Integrated team catches issues early | More common Risk Design gaps surface during construction |
| Owner Involvement | Streamlined Single point of contact simplifies decisions | More coordination required Owner manages communication between parties |
| Best For | Speed, certainty & multi-site programs Ideal when schedule, cost control, and accountability matter most | Projects with fully defined scope upfront Works when complete drawings exist before contractor selection |
When Design-Build Makes the Most Sense
Design-build shines on certain types of projects more than others. Here’s where it consistently delivers the most value:
Multi-Site National Programs
If you’re rolling out 15 restaurant locations or 30 fuel centers across multiple states, design-build gives you standardized delivery under one relationship. The team learns your brand standards, your operational requirements, and your approval process once. Then replicates it efficiently.
Aggressive Timelines
Lease commencements, franchise agreements, and competitive openings all run on fixed dates. Design-build is the best tool for hitting a hard deadline because it compresses the pre-construction phase and eliminates hand-off delays.
Projects With Evolving Scope
Sometimes owners know what they need functionally but haven’t locked down every design detail. Design-build accommodates that. The team can begin site work and structural decisions while interior details are still being finalized, rather than waiting for a complete set of drawings.
First-Time Commercial Owners
Managing a separate architect and a general contractor is a job in itself. For owners who don’t have a dedicated construction team internally, having one phone number and one point of accountability makes the entire process more manageable.
What to Look for in a Design-Build Contractor
Not every firm that calls itself a design-build contractor delivers the integrated process the name implies. Some are general contractors who added a draftsman to their team. Others are architecture firms that hired a project manager. The real thing looks different.
- In-house design and construction disciplines that have actually worked together, not just under the same corporate umbrella
- A track record of similar project types, not just similar sizes
- Transparent estimating from early in the design process, not at the end
- A clearly defined process for how design decisions and budget impacts are communicated to the owner
- References from owners who’ve completed multiple projects with them, which signals the relationship held up past the first handshake
Ask prospective contractors how they handle scope changes during construction, and how their design and field teams communicate day-to-day. The answers will tell you whether the integration is real or just marketing language.

Frequently Asked Questions About Design-Build Construction
- What is design-build construction?
Design-build is a project delivery method that places both design and construction services under a single contract with one firm. The owner deals with one team and one agreement from initial design through project completion, rather than hiring an architect and a contractor separately.
- How is design-build different from design-bid-build?
In design-bid-build, the owner hires an architect, gets completed drawings, then takes those drawings to bid for a contractor. The two firms work under separate contracts and have separate interests. Design-build puts them under one contract, creating shared accountability for schedule, budget, and quality.
- Is design-build more expensive?
Generally, no. Design-build typically costs less over the life of a project because early contractor involvement reduces design errors, there are fewer change orders, and faster delivery lowers carrying costs. Some owners see higher initial estimates compared to low-ball construction bids, but final costs tell a different story.
- How much faster is design-build?
Industry data consistently shows design-build projects deliver faster than comparable design-bid-build projects. The overlap between design and construction phases is the main driver. For commercial projects, this often translates to weeks or months of time saved.
- What types of projects use design-build?
Design-build is common across commercial construction sectors including hospitality, restaurant, retail, industrial, healthcare, and mixed-use development. It’s especially popular for national rollout programs and projects with fixed opening dates.
- Do I lose control of the design in a design-build project?
No. Design-build doesn’t mean the contractor makes design decisions without you. It means the architect and contractor are on the same team, which actually gives you more input because decisions happen in collaborative working sessions rather than across separate firms with separate agendas.
- What is a Guaranteed Maximum Price (GMP) in design-build?
A GMP is a contract structure where the contractor commits to a maximum cost for the project. If actual costs come in below the GMP, the owner typically shares in the savings. If costs go over, the contractor absorbs the difference. This is common in design-build and reinforces the cost accountability of the model.
- Can design-build work for phased or multi-site projects?
Yes, and it often performs best in those situations. A design-build contractor who delivers your first location learns your standards and operational requirements deeply. Each subsequent location benefits from that knowledge, which compresses both schedule and cost on future phases.
- How do I know if a contractor is truly a design-build firm?
Ask them to describe how their design team and construction team communicate on an active project. Ask for examples where design decisions were changed to reduce cost or improve buildability. Ask owners who have used them whether the integration was real in practice. Vague answers or ones that describe two separate departments is a red flag.
- How do I get started with a design-build project?
The first step is a consultation where the design-build team understands your project goals, site conditions, timeline, and budget constraints. From there, they can give you an early budget range and a proposed delivery approach.
