Commercial Design-Build That Delivers. One Team. No Excuses.
At Koehn Construction, we believe in taking the complexity out of construction. That’s why we specialize in the design-build method. Design-build is a streamlined approach that brings design and construction under one roof. Instead of juggling multiple contracts, you partner with a single team that’s accountable from start to finish.
From day one, designers, engineers, and builders work together as one unit, asking the right questions early, identifying potential issues before they surface, and staying aligned with your goals every step of the way.
The process starts with pre-construction planning, where we collaborate with you to define the project vision, budget, and timeline. With everyone at the table from the beginning, we keep things moving forward smoothly.
Design-build simplifies communication, improves efficiency, and creates space for real-time innovation. The result? Projects that stay on track, stay within budget, and meet your expectations, without the usual headaches.
Smarter Delivery Starts with Design-Build Construction
Design-build is a project delivery method that brings both design and construction together under one contract, managed by a single team. It creates a collaborative environment where everyone works toward the same goal from day one.
With design-build, Koehn Construction takes full responsibility for your project from the first sketch to the final walkthrough. That means fewer handoffs, fewer delays, and one point of accountability.
This approach helps streamline delivery, reduce risks, and keep budgets and schedules on track. By bringing designers and builders to the table early, we’re able to move efficiently and make smarter decisions every step of the way. The result is a construction experience that’s more coordinated, more responsive, and built around what matters most to you.

Your Design-Build General Contractor That Does Planning and Management Right
Efficiency Through Simplicity
No more chasing down your architects, contractors and vendors. Our design-build construction company takes responsibility for aligning everyone’s goals.
How We Do It
Long-Term Benefits
By building trust with architects from the start, our design-build approach leads to smarter projects, stronger partnerships, and long-term value. Early collaboration drives better decisions, fewer delays, and lasting performance well beyond project completion.
What This Looks Like
Our design-build process helps clients move forward with confidence, knowing their facilities will perform as promised today and stand up to tomorrow’s demands.
- Lower lifecycle costs – Smart design and material decisions made early help reduce maintenance, energy use, and repair costs down the road.
- Optimized building performance – Integrated teams ensure that systems (like HVAC, lighting, and utilities) are designed and installed to work together efficiently from day one.
- Built-in flexibility – Design-build teams often plan with future growth or adaptation in mind, making expansions or retrofits easier and more cost-effective later.
- Fewer headaches for ownership – With better coordination and communication upfront, there’s less risk of operational surprises or design flaws that need correcting years later.
- Long-term vendor and partner continuity – Relationships built through a design-build process often extend to future projects, streamlining future planning and creating trust with a team that knows your facility.
The Right Things at the Right Time
How We Make It Happen
We don’t wait for problems to show up; we plan for what’s next. Our team stays ahead of the curve with proactive scheduling, clear communication, and smart checkpoints that keep your project moving forward without the surprises.
Preliminary Drawings with Purpose
We use early-stage drawings to clarify scope, align expectations, and reduce costly revisions later on.
Cost Tracking at Every Phase
Ongoing budget updates help prevent overages and give you the flexibility to adjust scope before it impacts the schedule.
Milestone-Based Scheduling
We set firm handoffs between trades to keep everyone moving and minimize downtime.
Built-In Flexibility
If conditions change, we adapt quickly, without compromising quality or momentum.
Fewer Surprises, Better Decisions
With transparent reporting and clear planning, you stay ahead of issues before they become problems.
Design-Bid-Build vs Design-Build
We want you to know what you’re signing up for. Here’s a quick breakdown:
Design-bid-build splits design and construction into separate contracts. That means more meetings, more room for error, and more stress for you as the client.
Design-build flips that on its head. One team. One contract. One mission. We own it from sketch to steel, managing it all with less waste, less risk, and a hell of a lot more clarity.
We don’t wait for change orders to tell us what went wrong. We prevent them.
Sure, some clients still go the traditional route, but if you’re looking to save time, cut cost overruns, and actually enjoy the build process, design-build is the smarter path. And Koehn is the partner who makes it work.
Our Design-Build Process—Every Phase, Every Detail
As an experienced design-build contractor, we optimize traditional processes to reduce commercial construction project costs. In a traditional design-build or design-bid-build, owners or investors engage in exhausting talks with architects, engineers, and sometimes multiple contractors — our team helps this process run more smoothly and efficiently with fewer headaches for our clients.
Here is how we do it:
Design Team Selection
Putting the right specialists in the right place at every stage.
Architectural Design
Designing projects that meet needs and exceed expectations.
Pre-Construction Planning
We work with our architects and engineers to break the process into measurable phases that align with budget and timelines.
Construction Phase
We treat projects like our own and quality of work is number one. We ensure every detail is addressed and improve infrastructural and operational needs.
Post-Project Support
We discuss and handle ongoing maintenance and recommendations on how to further fortify a commercial space — perfect for busy people who prefer a hands-off approach.
A design-build firm’s key benefits include offering developers and investors critical oversight without requiring burdensome responsibilities.

The young athletes of Trident Aquatics, a sanctioned USA Swimming team, needed a state-of-the-art training facility that could double as a community aquatics center for the region. When it was time for Sean Callan, founder and coach, to make the new business a reality, he called on Koehn Construction to deliver the right solutions.
Creativity and collaboration drove the project. Callan and Koehn, partners on previous builds, brainstormed on ideas, leveraging Koehn’s experience with out-of-the-ordinary assignments to create a solid plan. And by collaborating with Cassandra Taylor of Architect One, Koehn was able to deliver a cost-effective solution for the building.
