Two of OCI’s Sewer Rehabilitation Projects recently received competitive construction bids that came in under the engineer’s estimates. OCI provided engineering design for a combination of spot repairs and relining sites for the City of Bellevue’s Sanitary Sewer Repair Project. The relining method used was Cured-In-Place Pipe (CIPP), and altogether the contract rehabilitated pipes at over 34 difficult site locations. The other project was for the City of Shoreline CIPP Storm Sewer Repairs, for which OCI completed CIPP relining design for 41 pipes. Both of these bids are the latest of multi-year contracts in which OCI has designed the relining of over 19,000 LF of sewers to date.
