Civil Engineering

Understanding Extremes Allows the Right Designs to Prevail

Our civil engineering consultants offer extensive design experience covering a broad range of projects. Our civil engineering capabilities include permit acquisition, design, and construction management. Permitting assistance experience includes permit application completion, permit drawing preparation, and permit submittal. We have also prepared complete permit packages for submittal to the appropriate agencies when multiple permits are required for one project.

We are particularly familiar with the unique civil design considerations of both cold regions including permafrost, high water tables, snow drifting, and frost heave, and those of the warm tropical climates subject to sea water, corrosion, and hurricane forces. We have the knowledge and experience to mitigate these problems in our designs.

Specific areas of civil design experience include:

  • Access/Public/Private Roads
  • Anti-Terrorism/Force Protection
  • Environmental Restoration
  • Erosion and Sediment Control
  • Ordinance/Franchise/Easement Development Assistance
  • Overhead & Underground Electrical Distribution
  • Permit Acquisition and Assistance
  • Pipelines
  • Site Development and Grading
  • Stormwater
  • Utility Delivery (including Combined Sewer Systems)
  • Wastewater Disposal
  • Water Treatment

“We have worked with Coffman Engineers for 15 or more years and found they are always willing to go that extra mile to get the job done on time. We value their input on our projects and find that with having Coffman review and prepare our designs makes our jobsites safer and work plans more efficient.”
