In 1985, WTA engineered the original Monsanto Chesterfield Campus buildings and infrastructure on the 210 acre site located in St. Louis County. Since then we have had a continuous presence assisting Monsanto with engineering projects including their separation from Pfizer, a project called “the Migration”.
For the Migration, WTA provided MEPF engineering programming, design and construction administration for the reorganization of research labs, offices and support spaces (approximately 2,400,000 sq.ft.) for Monsanto and Pfizer Corporations.
Since formal completion of the Migration work, WTA has continued to participate in design of campus building upgrades and modifications including the modernization and upgrade of utility systems for the complex.
