Civil engineers have a broad range of responsibilities in the planning, design, construction, and maintenance of infrastructure projects.
From project planning and site investigations to traffic engineering and regulatory compliance, civil engineers’ contribution to projects have a lasting impact on transportation, water resources, and the overall amenities of a community.
Transportation design and construction engineering inspection (CEI) are integral components of the planning, design, and execution of transportation infrastructure projects.
As design engineers create the plans and specifications, CEI professionals oversee the construction phase so that the design intent is faithfully executed and the final product meets safety, quality, and functionality standards. The collaboration between these two roles is essential for successful and sustainable transportation infrastructure development.
To make sure projects comply with environmental regulations and sustainability standards, our professionals assess the potential environmental impacts and develop strategies to minimize or mitigate any negative effects. This involves conducting environmental impact assessments, analyzing air and water quality, assessing soil contamination, and identifying potential risks.
With their specialized understanding of geology and managing of the interactions between structures and the Earth’s subsurface, our geotechnical professionals focus on the mechanical, thermal, and hydraulic behavior of soil and rock.
We contribute essential expertise to projects so structures are built on solid foundations and can withstand the unique challenges presented by the Earth’s subsurface conditions.
Construction materials engineering and testing verifies the quality, safety, and durability of construction projects. Our professionals work to assess and verify the properties of materials used in construction to maintain compliance with industry standards and project specifications.
These professionals are tasked with preserving the integrity and performance of construction materials throughout the project life cycle, and their efforts contribute to the overall quality and longevity of infrastructure and buildings.
Our professionals provide these essential components of any engineering projects by providing crucial data for planning, design, and decision-making.
Their work contributes valuable information that is foundational for engineering projects and provides accurate data collection, efficient planning, and effective decision-making throughout the entire project life cycle.
