We Design Bridges, Retaining Walls, Sound Walls, and Other Critical Structures

Mark Thomas has extensive experience delivering transportation, flood control, and wastewater structure projects. Our structural design expertise includes bridges, retaining walls, soundwalls, flood walls, water reservoirs, pump station housings, and other essential facilities. We provide both standalone structure design and integrated structural solutions as part of larger roadway, utility, or site improvement projects. We have also designed a range of bicycle and pedestrian bridge projects, including prefabricated spans, custom-designed crossings, and signature structures that serve as both functional infrastructure and visual landmarks.

Our retaining wall experience spans a wide range of applications, from standard cantilever and gravity walls to more complex systems such as mechanically stabilized earth (MSE) walls, tieback walls, and soil nail walls, tailored to meet site-specific conditions and geotechnical challenges. Our team brings a practical, cost-conscious approach that ensures our structures are durable, constructible, and aligned with the broader goals of each project.
