ST. LOUIS — The Center for Emerging Technologies (CET) has plans to construct a 60,000-square-foot laboratory building on a site adjacent to its existing two-building campus in St. Louis. Monsanto Co. has donated $1 million to help fund the $28 million project. Monsanto’s commitment is part of $3 million in private contributions needed for Phase I of the building, with an additional $6 million in contributions needed to complete the innovation center. Upon completion, the facility will feature 60 percent wet labs, with space for transitional research and a pilot plant. CET supports life science and other advanced technology companies with a range of research and development labs and support services. St. Louis-based Cannon Design is the architect for the project. The estimated date of completion was not disclosed.
