WallacePancher Group has over 50 years experience successfully managing County, City, and State Department of Transportation (DOT) projects of all sizes—including several major transportation projects and studies.

We prepare engineering studies, specific site analyses, and structural design of bridges, including foundations, retaining walls, and building structures. Our combined expertise also includes bridge inspection, bridge analysis, and structural design varying in size from small non-complex to large complex multiple-span bridges. This includes on-site consultation during construction.

All of our structural engineers are involved in bridge design, bridge inspection, and bridge load rating for maintenance, repair, rehabilitation, and replacement. Additionally, our team also helps design the new structures.

Our structural analysis and design software analyzes a broad range from simple stringers to continuous girders to finite element analysis. WallacePancher Group’s staff is involved in all aspects of a range of simple to complex bridge projects. This has led to our company’s recognition as a leading bridge engineering firm in the tri-state region.

Let the skilled professionals at WallacePancher Group help plan and design your next structural project to achieve maximum success.

What is Structural Engineering?

Structural engineering deals primarily with the design, analysis, and construction of structures to ensure their strength and stability. The practice combines scientific and mathematical principles to develop durable structures that can survive various stressors and environmental factors.

Structural engineers design a wide range of structures, like buildings, bridges, tunnels, and towers. A structural engineering firm collaborates closely with architects and other environmental consultants to create functional and aesthetically pleasing designs while considering the structural integrity of the project.

Some of the key elements of structural engineering include:

Structural Analysis – Performing calculations and simulations to assess the behavior of structures under different loads, including gravity, wind, seismic activity, and temperature variations.

Design – Developing detailed plans and specifications for the structural components of a project, including beams, columns, foundations, and connections.

Material Selection – Choosing appropriate construction materials based on their properties, performance, and cost-effectiveness while ensuring compliance with safety codes and regulations.

Construction Oversight – Collaborating with construction teams to ensure that the structures are built according to the approved designs and standards, conducting site inspections, and addressing any structural issues that may arise during construction.

Retrofitting and Rehabilitation – Assessing existing structures for potential weaknesses, deterioration, or damage. Then the structural engineering team makes recommendations for repairs, strengthening, or retrofitting to extend the structure’s lifespan.
