    @4240 in CORTEX, St. Louis, MO

As Construction Manager, Tarlton worked for Wexford Science & Technology to help transform the historic Heritage Building in the CORTEX District into a state-of-the art, multi-tenant laboratory and research facility. 

The $73 million historic renovation in the city’s Central West End kicked off Phase II of development in the CORTEX District. Tarlton renovated the core and shell of the 183,000-square-foot structure to meet the needs of established and emerging research and biotech companies and thought leaders, also completing several interior fit-outs for clients including Washington University, Cambridge Innovation Center, Boeing and Husch Blackwell. 

One of 20 projects Tarlton has completed or begun for Wexford, @4240 is expected to bring more than 450 high-tech jobs to St. Louis, with the core and shell completed at the end of 2013. The project is a finalist for a 2014 Keystone Award for Sustainability from the Associated General Contractors of St. Louis.

Formerly a Southwestern Bell telephone factory, @4240 earned LEED Platinum certification based on its sustainable design (by HOK) and construction. Sustainable features include energy recovery ventilation, permeable pavements and photovoltaic panels on the roof. The design also incorporates 500 large, industrial windows reflective of the originals and chosen to maximize natural daylight for all labs and office tenants. Skylights and light shafts spread natural light from above through the concourses and common areas on the lower floors of this three-story building.   

The main entrance was moved from Duncan to Boyle Avenue to face the new CORTEX Commons, an open space that will include a landscaped plaza and outdoor seating, serving as a hub for the entire CORTEX District.
