Traffic Planning

Traffic Signals 

Traffic Signals Make Transportation Safety and Traffic Flow Possible.

GHA’s traffic signal design experience ranges from ADA pedestrian safety improvements to multi-traffic signal corridor long improvement projects. GHA can study locations to recommend future improvements, design the new traffic signals, assist with resident engineer duties during construction, and even assist with signal operations after the traffic signal is built. Our experience with all phases of construction and maintenance of a traffic signal and roadway corridor allows us to design projects with their full life cycle in mind. Also, our close relationships with IDOT and other DOTs give us insight into design criteria and preferences, allowing us to truncate the review process

For more than 30 years GHA has provided traffic signal design for a variety of projects ranging from simple ADA pedestrian safety improvements to corridor improvements for entire traffic signal systems. GHA has been selected for Various / Various design contracts by IDOT and designed multiple corridor interconnect and signal replacement projects for LCDOT. GHA has the experience and ability to review the existing operations of an intersection and make recommendations to maximize the improvement budget by focusing on the changes that make a difference in real world operations. GHA can assist with new and modified traffic signals from concept through construction: completing warrant studies, design for new and modified traffic signals, provide resident engineer duties during construction, and even assist with signal operations after the traffic signal is constructed. Our experience with all phases of construction and maintenance of a traffic signal and roadway corridor allows us to design projects with their full life cycle in mind. Lastly, our close relationships with IDOT and other DOTs give us insight into design criteria, preferences, and ever-changing regulations, allowing us to maximize our efficiency and help mitigate potential for additional reviews.

Land Surveying

GIS, Geographic Information Systems

GHA’s Land Survey Group brings a level of experience far beyond most firms, and applies this to an extremely wide gamut of project categories, types of surveys, and time constrictions.

Reliable Excellence in Land Surveying Land Surveying is the unsung hero of civil engineering. With so much riding on the accuracy and level of detail, it is urgent that surveyors adhere to industry standards and best-practices that yield high-quality deliverables that lead to informed design.

Possibly our most beneficial advantage is that GHA is a civil engineering firm. This means that our surveyors are intimately familiar with exactly what is done with our surveying deliverables and why. Performing surveys from the engineering perspective has proven to provide us a definite edge in deep detail, resulting in highest-quality data. This is the data that defines the entire balance of project design.

  • Land Survey Services:
  • Boundary Survey
  • Existing Conditions & Topographic Survey
  • ALTA / ACSM Land Title Survey
  • Plat of Highways
  • Plats of Subdivision / Easements
  • Construction Layout
  • High-Definition Scanning
  • Manhole / Structure 3D Scanning


Construction Engineering

Proactive communication and effective coordination are vital to any project’s successful construction. GHA Construction Engineering focuses on impeccable documentation, a firm but fair collaboration with contractors, and actively reducing uncertainty for those affected by construction activity.

In the engineering phase that takes all the planning and intensive design and makes it a reality, there is uncertainty that can be mitigated with the right approach. For contractor and material accuracy and compliance, our trained eye and reliable processes match the high level of performance sought by project owners when seeking the right consultant.

The enemy of confidence for construction project stakeholders is uncertainty. The actual inconvenience experienced is undeniably unpleasant, but what residents, commuters, and the local business community really fears is not knowing what is being done, how long it will take, and why.

Construction projects commonly involve changes and delays. This is counterintuitive to projecting the perception of intentional, well-planned construction activity. This leaves only preemptive timeliness as the most important tool. Over the years, it has been common to generate newsletters, flyers, and other communications channels to manage the emotions of project stakeholders.

We know that today’s immediacy is demanded by the public, and while hard-copy methods may still need to be included, the most helpful channel to connect with those most interested in remaining fully informed is a project-specific website GHA brings strong experience in utilizing a project-specific website to inform stakeholders about the project and is the most common method chosen and most conveniently consumed.
