If you're planning a commercial construction project in Southern Illinois or the St. Louis Metro Area, one of the first decisions you'll face isn't about materials or timelines — it's about how your project will be delivered.
Two of the most common approaches are
design-build and
traditional general contracting. Both can produce outstanding results, but they work very differently — and choosing the wrong one for your project type can cost you time, money, and a lot of unnecessary stress.
At Korte & Luitjohan Contractors, we've been helping
businesses,
municipalities,
healthcare organizations,
schools, and
industrial clients navigate this exact decision since 1958. Here's what you need to know.
Design-build is a project delivery method where a single entity — your contractor — is responsible for both the design and the construction of your building. Rather than hiring an architect separately and then putting the project out to bid, you work with one team from the very first conversation to the final walkthrough.
In a design-build arrangement, the designer and builder are on the same team, working toward the same goal: delivering your project on time, on budget, and to your specifications.
Design-build is often the right fit when:
- You have a clear vision for the outcome but want a single point of accountability
- Your timeline is tight and you can't afford the back-and-forth of a traditional bid process
- Budget predictability is a top priority
- You're building something new — a new commercial facility, warehouse, healthcare clinic, or municipal building — from the ground up
In a traditional general contracting model (sometimes called design-bid-build), the design and construction phases are separated. You typically hire an architect or engineering firm to develop plans first, then take those completed plans out to bid. A general contractor is then selected and hired to build according to those drawings.
This is a time-tested model that works well for many types of projects — especially when you already have detailed plans, need to meet specific public bidding requirements, or are working on a renovation or expansion of an existing structure.
General contracting is often the right fit when:
- Plans are already complete or nearly complete
- The project involves renovation, historic preservation, or additions to an existing building
- Public funding or municipal regulations require a competitive bid process
- You want independent oversight between the design and construction phases
Key Differences at a Glance:
Single point of contact: Design-build gives you one team for both design and construction. Traditional general contracting involves separate firms for each phase.
Timeline: Design-build typically moves faster because design and construction phases can overlap. Traditional general contracting requires completing design before construction can begin.
Budget control: Design-build tends to offer stronger cost certainty earlier in the process, since the builder is involved in design decisions. With traditional general contracting, cost surprises can emerge when bids come in higher than the architect's estimates.
Accountability: With design-build, there's no finger-pointing between the designer and the builder if something doesn't go as planned — it's one team, one responsibility. In a traditional model, disputes between architect and contractor are more common.
Flexibility: Traditional general contracting can be a better fit when detailed plans already exist or when procurement rules require it, such as with certain public projects.
Which Approach Is Better?
Honestly? Neither is universally better — it depends entirely on your project.
If you're a healthcare system planning a new clinic in Belleville, a manufacturer expanding your facility in Granite City, or a school district building a new administrative building in Highland, design-build may give you the speed and budget certainty you need.
If you're a municipality in Edwardsville completing a renovation that requires a public bid process, or a business owner expanding an existing building with plans already in hand, traditional general contracting may be the better path.
The good news is that you don't have to figure this out alone. A contractor with experience in both methods — and deep roots in the region — can help you make the right call before any money is spent.
Why It Matters Who You Work With
Regardless of which delivery method is right for your project, the most important factor is the experience and integrity of the team you hire.
At Korte & Luitjohan Contractors, we've delivered projects across both methods for clients in commercial, financial, healthcare, education, historic renovation, municipal, infrastructure, and industrial markets throughout Southern and Central Illinois and the St. Louis Metro Area.
We understand local permitting processes, regional subcontractor relationships, Illinois building codes, and the specific challenges that come with building in our part of the country. That local knowledge isn't something you can get from a firm that parachutes in from out of state — and it makes a measurable difference in how smoothly your project runs.
Since 1958, our reputation has been built on delivering what we promise: safe jobsites, quality craftsmanship, and honest communication from the first call to the final punch list.
Frequently Asked Questions:
Can Korte & Luitjohan handle both design-build and general contracting projects?
Yes. We offer design-build, general contracting, construction management, and pre-construction services. We'll help you determine which approach best fits your project during an initial consultation.
Is design-build more expensive than general contracting?
Not necessarily. In many cases, design-build can actually reduce overall project costs by catching design issues early, reducing change orders, and shortening the overall timeline.
Do municipal or government projects have to use traditional general contracting?
Some publicly funded projects do require a competitive bid process, which means traditional design-bid-build. We have extensive experience working with municipalities across Southern Illinois and can help navigate those requirements.
What types of commercial projects does K&L handle?
We work across a wide range of markets including commercial, financial, healthcare, education, historic renovation, municipal, infrastructure, and industrial projects throughout Southern/Central Illinois and the St. Louis Metro Area.
