An existing, thirty year old, cast-in-place concrete structure was extensively modified to perform as a state-of-the-art water quality laboratory and facility, with provisions for administrative space and public conference rooms.

The Phase II expansion of this water treatment plant in Vallejo, relocated engineering and administrative offices and added a lunch room for chemists, administrators and the maintenance crew. LCA Architects worked closely with city staff at the onset to clearly define the scope and the process of the project to create a seamless addition to the existing building. Inspection to evaluate current usage and help assess future space needs was also part of the project which included presentations to city council and city staff. LCA took special care in planning the plant’s new maintenance shop, as it had the highest square footage cost. Attention was paid to its special programming needs which included a maintenance bay with a 5-ton bridge crane and adjacent workshop.
