This renovation converted an existing warehouse into a food processing and manufacturing plant for oat-based milk foods. Included in the scope were a research and development lab; processing, assembly, cold storage, warehouse and shipping areas; office support spaces; and a new 11,000-sq-ft mezzanine. The processing areas dictated the use of specialized materials throughout the facility and precise tolerances for door, window and wall systems. Insulated metal panels create a high-performance building structure with no voids for bacteria to grow. The constrained site inside a busy, operational industrial park is bound by a Union Pacific Rail spur, and construction crews had to work around four existing electrical services and a 22-ft-deep sewer receiver and its associated drain piping.
