Building for Future Generations

Within K12 and higher education, there is a transformation of space. Classrooms, art studios, laboratories, theatres, and dining halls are being reimagined and designed to optimize the learning environment.

As one of South Carolina’s premier education builders, Trehel Corporation has partnered with numerous private academies, public school districts, private colleges, and public universities. We have extensive project approach experience providing Design-Build and Construction Manager at Risk (CMAR) services. Additionally, we provide guidance through the building process, driven by your objectives to prepare students for personal and professional success.

With the cost of education outpacing inflation, Trehel has a well-developed process to produce accurate cost estimates and timetables that work within budget and minimize disruption. Today’s learning environments must be cost-effective and sustainable.


Making the Grade

Trehel provides a detailed framework for preconstruction, construction, and bond strategy. Our team welcomes opportunities to build or upfit facilities utilizing any of the Green Building Rating Systems available in our market. Following these guidelines will improve performance metrics, such as energy savings, water efficiency, indoor air quality, and more. Trehel has experience working with the sustainability building certifications, led by our Director of Project Collaboration, Kevin Gillenwater, LEED AP BD+C, WELL AP, GGP.

However, even when the project will not be certified using a Green Building Rating System, we continue with our standards to operate with greater efficiency and reduce the impact of the built environment on our planet.


From the first budget to the completed project, our experienced education construction team will deliver a facility tailor-made for your learning environment.

Project Collaboration

At Trehel, we adhere to a collaborative team approach. The ideal partnership is transparent to all and built on trust, humility, and a healthy appreciation and respect of each person’s roles and responsibilities.


Early in the preconstruction phase, Trehel will offer creative solutions for site work, mechanical systems, electrical solutions, and building materials to guide our clients in deciding how best to allocate funds within their budget.


Our project teams have more than a 40-year track record of completing successful, cost-effective, quality projects for our clients. In addition, we are very adept at working with architects, engineering consultants, and subcontractors, with the client's input, to achieve your project's overall vision.


In addition to our TQM process during construction, Trehel provides a TrehelCare Customer Service Representative dedicated to following up on any warranty items after completion. Besides our ongoing customer service, on the first anniversary of completion, a visual site inspection is provided to address any issues that may have arisen.

Every single project that Trehel has completed for the SDOC has been on time and on/below budget. The projects have also been completed just as they were designed with quality work and craftsmanship. No project is done anywhere without day-to-day construction issues that arise. When those have occurred on our projects, Trehel has been quick to resolve the problems and make sure that we are satisfied with the results. Their project managers and superintendents are up front and act with care and integrity.

Being open and honest without concern of reprisal or reprimand is the most productive means of managing projects. It is much better to have everyone involved working on any issues that do come up. With Trehel, I feel like I always get the most qualified and professional site superintendents, project managers, and estimators on my projects. There is no question that we are all on the same team with the same goals.

We had a great working relationship with Trehel – everyone on the team was honest and up front re: everything and explained the process in detail. It was nice to walk through the details during the entire building experience (i.e. they held our hand throughout the entire process).
Scott Brand

They took the time necessary to answer questions, explain “the process” over and above my expectations such that I felt totally comfortable with what were about to undertake… we had built multiple residential homes, but never any commercial construction… the education, explanation, and clarity provided by Trehel made our choice a no brainer.

As a Chef and Kitchen designer I have worked with numerous contractors. Trehel was by far the most experienced in my 43 years in the industry. They listened to my concerns and worked with me day by day through challenges. It was an absolute delight to work with the Trehel project team. Total professionals and always looking out for the “owners’ and what they needed.

Trehel has always had a great reputation, they were local to us and well known for problem solving.  We had been looking for an opportunity to use them when we came across our project in Athens GA.

Actually, we brought them in late to the process.  We were working with other contractors and struggled to hit our budget needs.  As such, we summoned Trehel’s help to get the project design back within our budget.  Trehel played a critical role with recommendations that would allow us to meet our budget goals and without compromising the overall project.

I worked primarily with Greg Blinston, VP and Senior Project Manager and I can confidently say that his effort made this experience better than I thought was possible. I always felt he was working for me and we were working as a team to complete this project. There was very clear understanding of what the budget included and the timeline of how the project should go was very different from every other contractor I had worked with and a distinction from other contractors.

It is hard to imagine that I could be any happier with the experience with Trehel.  If I ever have another building project, I know Trehel is where I will go and would recommend anyone to use Trehel.

We had a fourteen-million-dollar renovation project, and we had to trust that Trehel would complete it before the deadline, only five months away. There was no room for error. And Trehel delivered. We couldn’t ask for a better building partner. They truly walk the talk.
Craig Brown
President and Owner
of the Greenville Drive

They definitely asked the right questions and were able to understand and articulate that into a plan that worked for us. They came within the exact penny they said they would. So, if you really map it out, I will say that they met the expectations of quality, price, and timing, but they exceeded expectations for how much we enjoy our building.

I highly recommend Trehel Corporation as a General Contractor. I have personally worked on a number of construction projects and would say that Trehel Corporation and all their employees have been a true pleasure to work with. If in the future we would want to build again, Trehel Corporation would be the first company I would contact. Please feel free to contact me with any questions or to discuss my experience working with Trehel Corporation.

It is difficult to explain in words the appreciation I have for the entire team at Trehel.

Our journey together began approximately 2 years ago with the complete renovation of the casual dining space in our Clubhouse. This would be the first of several projects we entrusted to Trehel at Wade Hampton Golf Club. Our projects culminated with the construction of our new employee housing building.

The membership is pleased with all the work and early responses I have heard indicate we have exceeded their expectations. I can say with confidence that Trehel will be my first choice of contractors when we take on future projects.

Trehel has been a responsible, trustworthy partner to Blue Ridge Electric for many years. We set high standards, and Trehel has always met or exceeded our expectations on every project. Trehel has also been a good community partner, which as a community-focused organization ourselves, means a lot.
