Calibre provided preliminary and final design of a parallel upsized replacement of the sanitary system along Lima Alley, Paris Alley, and Montview Boulevard. The design addressed on-going system back-ups between Lima and Macon Street (8-inch CIPP) and along the alley between Paris Street and Peoria Street (8-inch VCP). The project included assessing the condition of the pipes and the downstream connection pipes, coordinating survey and geotechnical subconsultants, coordinating and overseeing construction, and providing construction administration. The wastewater lines total approximately 20,000 LF. 


The project required three tunnels:


1. Lima Street and Colfax Ave (12, pipe burst)


2. 14th Avenue and Peoria Street (12, pipe boring via guided ram)


3. Oswego and Colfax (12, hammer boring)
