RELEVANT SERVICES
As the prime consultant of this PS&E project, infraTECH was responsible for the design of the US 75 main lane widening, reconstructing entrance and exit ramps, frontage road, bridges, retaining walls, drainage, signing & pavement marking, signal, illumination, ITS and SWPPP. Additionally, infraTECH managed the storage and organization of all project files. infraTECH worked closely with TxDOT and teaming partners including HDR, ATKINS, Aguirre & Fields, PGAL, Gauge, HVJ and GAI to complete this accelerated schedule project on time.
“infraTECH team recently completed PS&E package for US 75 Segment 5, the largest ongoing project with accelerated schedule in Paris District. With out of the box thinking & proactive approaches, infraTECH have exceeded project requirements, maintained budget, & advanced schedule. Through effective communication, they also minimized utility impact and ROW issues. Without these proactive attitudes from infraTECH, it would be impossible for the District to complete this project in a very accelerated schedule effectively.”
