Construction cost estimating provided to the owner at the conceptual and schematic design levels for 15,411 sq. ft. renovation at Backyard Farms headquarters in Madison, ME. The renovations were within two greenhouses, work included renovations/expansion of existing office space, cafeterias, locker space, and entry spaces to limit contamination within the greenhouse area. The greenhouse spaces were extremely controlled and needed to be separated from possible contamination. PCM developed detailed conceptual estimates for multiple design options and worked closely with the design team to develop cost-saving measures.
