TW Construction

TW Construction Commercial General Contractor, Construction Manager It all came together in 2005 when Jerry and Donnie opened the doors to their own enterprise.

The Therrien Waddell Construction team began its incubation in the 1970s.“I had been in the construction business for a few years, and here is this guy fresh out of college on the construction site,” said Donnie Waddell. Young Jerry Therrien proved to be a quick learner, and he and Donnie built a mutual respect for each other from the ground up, moving earth and building structures together, and u

ltimately leading the construction operations of two development companies over the next decades. Over the years, Jerry and Donnie built reputations based on honesty and unwavering values.They experienced the integration of leasing requirements, lenders, property management, government regulators, design needs, building efficiency, schedule imperatives and cost control lessons through a vast variety and scope of projects. Donnie explained the partnership as “a natural path to the next phase in our evolution. Together, we learned the value of viewing the project from different perspectives. We learned the right way to treat people and to execute plans.”

The most important part of history is how it shapes the future. “In 2005, our time had come,” said Jerry. “We had experience, maturity, professional credibility. We built great industry relationships. It was the right time to pull all of the experience and relationships together.” The partners recruited trusted and experienced people from the industry with whom they had history. Today, many of those people are still part of the business family formed by Jerry and Donnie. In the decade since TW was formed, the team has been awarded some prestigious honors for a variety of projects. Our expertise has expanded into a broad range of project types. Although we have grown in breadth and depth, our fundamental values will never change:

We treat others as we want to be treated. We look for ways to make every project exceptional. We honor our communities through service.

QUALITY ASSURANCE IS A MUST. We are committed to using the quality materials and adhering to stringent safety standards. This dedication to excellence means that we deliver structures that stand the test of time.

Finally, it’s essential to consider the CULTURAL FIT between you and your construction partner. A shared vision and values can significantly impact the project experience. We believe in building relationships that go beyond the construction site.

Turning a setback into success—we’re excited to be working on the reconstruction of a 7,000 SF warehouse in Rockville, Maryland for Bristol Capital Corporation. This project is more than a renovation; it has been about rebuilding what was lost and restoring functionality after a fire partially destroyed the structure in 2023.

Working alongside WHS Architects, we demolished the fire-damaged half of the building while preserving and revitalizing the remaining structure. Our scope includes:

✅ Rebuilding to original specifications by constructing the lost half with concrete masonry (CMU) walls
✅ Enhancing functionality by installing new storefronts, overhead doors, and skylights
✅ Improving infrastructure by adding new restrooms and a brand-new roof across the entire building

At ThirdWall Construction, we thrive on projects that require creative solutions and expert ex*****on. If you're planning a new build or a renovation, let’s talk about how we can bring your vision to life.
