TECHNOLOGIES & PROCESSES

Construction of the City of Woodstock's 2025 Enhanced Street Program, which improves 8.4 miles of roadway, began last month. These improvements include both resurfacing and reconstruction of local residential/commercial streets, as well as higher traffic volume collector and arterial streets. During the design phase, TAI engineers performed a comprehensive evaluation using pavement cores, PCI ratings, and in-person field assessments to determine the most cost-effective and appropriate improvement for each roadway segment. To maximize value and minimize disruption, cement-stabilized full-depth reclamation (FDR) was selected as the reconstruction method for qualifying streets. FDR recycles the existing aggregate and subgrade materials by blending them with Portland cement and water, creating a strong, stable base ready for paving, without the need to haul in new aggregate. This sustainable approach not only reduces cost and environmental impact but also significantly minimizes disruption to residents. We’re proud to partner with the City of Woodstock in delivering efficient solutions for our municipal clients and their residents. 

The Village of Hanover Park wastewater treatment facility at 5600 Greenbrook Blvd. was originally constructed in the early 1970s and has undergone several major expansions and rehabilitations. The last major rehabilitation occurred roughly 20 years ago, and the UV disinfection equipment on site today dates to the 1997 expansion. The project includes removing and replacing the three Trojan 3000 units with two Trojan 3000+ units. This project received a grant from the USEPA for roughly 72% of the construction costs, and construction will begin in the Spring of 2024.
