A total of 28 modular units were fabricated offsite and delivered to the jobsite with the interior room finishes complete. single-room, two-room, and three-room modular units were fabricated. Prefabricated room types included clinical support, exam, procedure, and toilet rooms. The clinical support, exam, and procedure rooms received finishes including painting, wall protection, casework, ceiling grid, mechanical trim, and electrical trim. 

Prefabricated wall panels also were built offsite for multiple interior wall partitions throughout the space. The wall panels had metal stud framing and in-wall electrical rough-in completed before setting onsite. Some wall panels were set prior to the modular room delivery as well as after where walls tied into room locations.
