Big-Firm Capabilities. Small-Team Attention.
Terrapin Construction Group is a nationwide commercial general contractor and design-build firm — delivering precision, professionalism, and national reach without the overhead. Licensed and active in all 50 states, from concept through closeout.
Built on a Simple Insight
The TCG leadership team spent years managing complex, high-stakes commercial construction projects — many exceeding $100 million — for some of the largest firms in the industry. Across all of those projects, one pattern emerged: the actual execution always came down to a handful of highly capable people.
Despite sprawling teams and multi-layered processes, lean groups of skilled professionals consistently outperformed bloated organizations on speed, quality, and cost-efficiency. That insight became the foundation of Terrapin Construction Group.
We launched TCG with a clear mission: to bring the precision, professionalism, and national reach of a large firm without the overhead. Since then, we have delivered design-build commercial construction across all 50 states, consistently meeting aggressive timelines and strict budgets. Our agile, expert-driven approach gives clients big-firm capabilities with small-team attention.
At Terrapin, we are not just building structures — we are building trust, efficiency, and lasting partnerships across the country. We work closely with NAIOP-affiliated developers, BOMA-managed property owners, and the institutional capital partners shaping commercial real estate in 2026.
What Makes Us Different
National Reach, Local Expertise
We have built enduring relationships with subcontractors, suppliers, and consultants in every state. For each project, we assemble the right regional team — matched to local codes, labor markets, and delivery dynamics — while providing national-caliber oversight from our Denver, Houston, Albany, and Sheridan offices.
Design-Phase Discipline
Our team is structured to support the early-phase services that matter most. From cost modeling and feasibility studies to constructability reviews and value engineering, we align design decisions with real cost data and buildable sequences — so what is drawn on paper translates to what is built in the field.
Transparent Partnership
Clear budgets, real-time reporting, and proactive problem-solving at every stage. We view ourselves as an extension of our client's team — advocating for their goals from concept through closeout. Challenges are anticipated early and solutions are shared openly. No surprises.
Technical Precision Across Sectors
From medical facilities and biotech labs to cannabis cultivation and data centers, we bring the specialized knowledge that technically demanding projects require — balancing regulatory compliance, systems integration, and mission-critical deadlines.
Self-Performing Specialties
TCG self-performs insulated metal panel (IMP) installation, pre-engineered metal building erection, and equipment procurement and installation. Controlling these critical scopes in-house means we directly influence cost, schedule, and quality — no middleman.
Integrated Delivery
Architecture, structural engineering, MEP engineering, preconstruction, and construction management under one contract. Smoother transitions between design and build, fewer change orders, and a facility ready to perform from day one.
The Team Behind TCG
TCG was founded by three construction professionals who saw an opportunity to deliver better outcomes through a leaner, more accountable model. Together, they bring over 50 years of combined experience across commercial, industrial, healthcare, and agricultural construction.
William C. Goodin
Will leads TCG's early-phase project strategy — guiding opportunities from concept through contract execution. He oversees client engagement, preconstruction coordination, and design-phase management to ensure every project is aligned with cost, schedule, and performance goals. With over 25 years of experience and his ICC Certified National Standard General Building Contractor (Class A) certification, Will seamlessly integrates construction management with operational strategy. Prior to TCG, Will served as VP of the Project Management Office at Urban-Gro, Inc. (NASDAQ: UGRO) and founded multiple firms including REI Capital, BWI Capital, Rubix Group, FlexMOD, and GroAdvisor — having successfully completed hundreds of design-build projects across the USA and abroad.
Ben Merritt
Ben brings more than 18 years of operational and leadership experience to TCG, providing both strategic oversight and practical, day-to-day guidance that keeps the firm running with precision and efficiency. He excels at developing scalable systems, optimizing resource allocation, and implementing best practices that enhance performance across all projects. Ben's proactive leadership style and commitment to continuous improvement allow him to identify challenges early, drive swift resolution, and uphold rigorous standards of quality, safety, and timeliness. His operational expertise is central to advancing TCG's mission of excellence and reliability.
Nathan S.
Nathan is a founding member of TCG and serves as Vice President of Construction Services, bringing more than 16 years of construction industry experience with meticulous attention to detail, technical depth, and a highly engaged management style. He provides executive oversight across all active projects, leveraging his broad knowledge of delivery methods and construction management best practices. Nathan works seamlessly with design teams, owners, and trade partners to guarantee that each project is constructible, efficient, and aligned with both schedule and budget expectations. His early involvement in every engagement — from preconstruction through closeout — allows his team to anticipate challenges, implement proactive solutions, and maintain momentum. Nathan's leadership has become a defining element of TCG's reputation for precision, accountability, and consistently exceptional project outcomes.
Working with TCG was one of the best decisions I have made for my business. From day one, they provided an unmatched level of guidance and expertise. The budgeting and scheduling process was refreshingly straightforward — they walked me through the reasoning, the options, and the potential impacts. Our multiphase commercial development was completed on schedule and under budget. I never felt like just a client — I truly felt like a partner.

Design-build is a project delivery method that combines design and construction under one contract — compressing schedules 15 to 30 percent, providing single-point accountability, and eliminating the adversarial dynamic between designer and builder typical of traditional design-bid-build projects. TCG integrates architecture, structural engineering, MEP engineering, and construction under one team. The Design-Build Institute of America recognizes design-build as the fastest-growing project delivery method in U.S. commercial construction.
Yes. TCG self-performs insulated metal panel (IMP) installation with over 1 million square feet installed across 38 states, pre-engineered metal building erection, and equipment procurement and installation. Self-performing these critical scopes gives TCG direct control over cost, schedule, and quality on every project.
The fastest way is the free TCG.ai construction estimator, which delivers preliminary cost benchmarks across every commercial building type. For envelope-heavy industrial work, the IMP Install Estimator prices supply-and-install scopes in real time. For projects past the LOI stage, TCG's preconstruction team delivers a hard-priced preliminary budget within 5 business days. Schedule a consultation to discuss your specific project.
TCG handles commercial construction projects ranging from $1 million to $30 million in typical contract value, with capability scaling on a case-by-case basis through subcontractor coordination on larger projects. Project footprints range from small tenant improvements (under 5,000 SF) to industrial and agricultural facilities exceeding 500,000 SF. See the project portfolio for representative examples.
No. TCG provides full in-house architectural design through our partnership with 3rd Act Architecture, plus structural engineering and MEP engineering through our partnership with 9BA MEP Engineering. If you already have completed plans, TCG can also bid or build from existing documents as a general contractor.
Yes. TCG operates a dedicated broker partnership program for commercial real estate brokers nationwide.

TCG combines big-firm capabilities with small-team attention. Three differentiators stand out: nationwide licensure (all 50 states with one accountable partner), self-performed specialty scopes (over 1 million SF of IMP installed, plus PEMB and equipment procurement), and integrated design-build delivery under one contract. The lean operating structure means partners are directly engaged on every project — no layered communication, no estimator-to-PM-to-superintendent gatekeepers.
