Western Specialty Contractors’ Peoria, Ill., branch recently completed the roof on a 500,000-square-foot, $30 million warehouse expansion in Normal, Ill., for the electric vehicle manufacturer Rivian. The addition doubles the size of the existing facility. 

Western, which is based in St. Louis and has 30 branch offices nationwide, says its craftsmen installed a mechanically fastened TPO membrane roof with R-30 minimum insulation, tapered insulation crickets, perimeter coping caps and expansion joints. The lightweight, flexible TPO roof provides a reliable, economical and energy-efficient solution for a job of this magnitude, the company added.

Rivian produces its all-electric R1T and R1S models and electric delivery vans for Amazon at a production facility about six miles west of the warehouse. According to reports, Rivian has experienced major growth in recent years to become the second largest employer in the Bloomington-Normal community with a reported 5,075 employees.

The general contractor on the warehouse expansion project, Peoria-based PJ Hoerr, selected Western to install the facility’s new roof. Zimmerman Architectural Studios was the architect of the project. 

In its statement, Western says it was able to maneuver the supply chain crisis due to its strong partnerships with suppliers and manufacturers to procure all necessary roofing materials to complete the project on schedule.
