Subcontractors <br />have completed electrical conduit installation within the electrical room, floor slabs throughout the facility <br />and framing of the administration spaces. Subcontractors have completed all CMU block work for the <br />facility. Steel beam installation has been completed in the WTP. Site piping has been installed for sanitary, <br />storm, raw, and finished water connecting to utility in the right of way. Process piping continues to be <br />installed in the pipe gallery and is about 90% complete.
