Brudis & Associates, Inc. (BAI) was responsible for preparing complete construction plans, specifications and cost estimates to relieve congestion and improve safety at the intersection of US Route 40 (Dual Highway) and Mt. Aetna Drive in Hagerstown. The project included reviews and approvals from both the Washington County DPW and various Maryland SHA divisions.
The project involved initial traffic engineering analysis, including Synchro/SimTraffic modeling and simulation, vehicle queue determination, signal timing and phasing, capacity projections, level-of-service, and safety evaluations.
Roadway/Intersection and Traffic Signal Designs:
Upon completion of the traffic engineering study, BAI prepared preliminary and final engineering construction documents. The engineering design involved auxiliary lanes along both US 40 and Mt. Aetna, safety grading and drainage, determination of right-of-way acquisition, storm water management design, erosion and sediment control, full-depth pavement widening and resurfacing, horizontal and vertical re-alignment, sidewalks and ADA compliant curb ramps, and a new closed drainage system to tie into an existing system. BAI’s design also included ¼ mile of full-depth widening along Yale Drive at the intersection with Mt. Aetna.
BAI was also responsible for detailed construction documents for two (2) traffic new signals, ADA signals, signing and pavement markings for the project. In addition, BAI’s design incorporated multiple stages of construction which maintained vehicle and pedestrian access during construction.
Project Coordination/Construction Phase Services:
The design also included extensive utility identification, coordination, design modifications, and relocation. This included water, sanitary sewer, electric/power, communications, and natural gas. BAI also provided construction phase services including response to contractor questions, approval of material substitutions, and in-field contractor meetings. The project was completely constructed at a cost of approximately $1.25 million which was $60,000 below BAI’s engineering estimate.
