We’re proud of our impact on transformative projects across the country. For the Michigan Department of Transportation (MDOT), we’re tasked with data collection on an ‘as-needed’ basis for the monitoring and evaluation of 36,000 miles of federal-aid roads in Michigan, with additional reporting requirements for the 83,000 miles of non-federal aid roads. This includes uploading the collected data to MDOT’s Traffic Data Management System (TDMS) for quality and reasonableness evaluation.

In Illinois, our team was selected by the Illinois Department of Transportation (IDOT) for the collection of 24-hour Passive Magnetic Sensor (PMS) counts, spanning the Mississippi River to the Indiana state line, and from the Wisconsin state line to the area surrounding Peoria. We’re honored to be selected once again by IDOT for the 2022-2023 contract, encompassing more than 8,000 locations and various count types. Since 2005, we have completed more than 37,000 24-hour volume and vehicle length counts. In the past six years alone, we have collected more than 7,500 counts within the City of Chicago.

Our reputation as a leading company in the practical application of technology is driven by our passion for innovation. To enhance the value we provide our clients, we offer online requests for traffic counts and stand as one of the first data collection firms to supplement collected traffic data with GPS data.

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.
