Your Commercial General Contractor. Plans in Hand.Build Begins Now.
Plans. Budget. Timeline. You need a contractor who executes without excuses.
What It Means to Hire a Commercial General Contractor
When you bring Koehn Construction Services your construction documents, you're handing them to a commercial general contractor that self-performs earthwork, concrete, and site utilities. Most GCs subcontract all three the moment a job starts.
When KCS runs those trades directly:
The projects vary: manufacturing companies, private developers, multi-location business owners. The approach doesn't: know the job, build the plan, execute it clean.


For Business Owners Who Don't Have Time to Babysit a Build
Your design is done. Your architect is locked in. You need a contractor who will treat the drawings like a commitment. Not a starting point for renegotiation.
That's the plan-and-spec environment we work well in. We ask the questions that catch issues early. We hold subcontractors to the same standard we hold our own crews. You get a direct line to your project manager - not a general inbox.
If the drawings aren't done yet, start with design-build. You'll save money making changes on paper than in the field.
What KCS Brings to the Job As Your Commercial General Contractor
Self-perform depth.
KCS crews handle earthwork, concrete, and site utilities in-house. No handoffs on the trades that set the pace for everything else.
Subcontractor coordination.
We prequalify every sub before they're on the job and hold them to schedule. One trade running late doesn't become your emergency.
Budget discipline.
The budget is built before ground breaks and tracked every phase. If something shifts, you hear it from us first.
Project manager access.
Every project has one dedicated PM from start to finish. You know who to call, and they know every detail of your project.
What to Expect When
You Work with KCS

Pre-Construction
Once we have your documents, we get to work before ground breaks. We review the drawings, finalize the budget, build the schedule, pull permits, and prequalify subcontractors. Nothing moves to the field until the plan is solid.
Construction
Your PM is on the project daily. Trades are sequenced and held to schedule. You get regular updates - not silence followed by surprises. If something comes up, you hear about it with a solution attached.

VIEW THIS PROJECT →Common Questions About Hiring a Commercial General Contractor
What does a commercial general contractor actually do?
+A commercial general contractor manages the build from groundbreaking to completion. That means coordinating trades, tracking the budget, handling permits and inspections, and staying ahead of problems before they cost time. At KCS, we also self-perform concrete, earthwork, and site utilities. That gives us more direct control over cost and schedule than a contractor who hands all of that off.
What's the difference between a general contractor and a construction manager?
+A general contractor holds the contract and takes on the risk of delivering the project for an agreed price. A construction manager works for the owner in an oversight role without holding the subcontracts directly. The right fit depends on your project and how far along your design is.
Do I need to have my plans finished before I contact KCS?
+Not necessarily. If your plans are complete, general contracting is a clean path forward. If you're still in the design phase, design-build gets KCS involved earlier. That usually saves time and money before anything is committed to paper.
What size commercial projects does KCS take on?
+KCS handles everything from tenant improvements and building additions to ground-up facilities and full site development. We've worked with manufacturers, healthcare clients, municipalities, and private developers. Not sure if your project is a fit? Reach out and we'll tell you straight.
How does KCS handle subcontractors on a GC project?
+We prequalify subs before they're on the job - licensing, insurance, references, financial stability. On site, they're held to the same schedule and quality standard as our own crews. We manage trade sequencing and stay ahead of bottlenecks. One sub running behind doesn't turn into your problem.
