Client: North East Ohio Sewer District (NEORSD)
Location: Ohio, USA
Project Value: $9.6m
Description: General Contractor for the Construction, Microtunnelling, Dual Force Main, Pump StationUpgrade, Tie-ins and Permanent Concrete Works for the Relief Sewer in Cleveland, Ohio, USA
This project provided for the construction of sewers, sewer relief and consolidation structures, along with the update of several regulators.
WLLRS-3 was removed and a single drive of 1825LF between WLLRS-1 and 4 was constructed thanks to a value engineering proposal from Ward and Burke Tunnelling. WLLRS-3 was eliminated from the project as its construction would directly affect existing underground infrastructure and overhead hydro lines. By not relocating this existing infrastructure with in the temporary easement time and cost savings were achieved for the client.
The project involves two live tie-ins to existing 36” (3.6 MGD) at WLLRS-1 and WLLRS-4. This was completed using a specially designed hydraulic flume. WLLRS-2 was tied in to an existing 9’x4’ box culvert.
Located in an environmentally sensitive area due to construction within contaminated ground, this project involved the construction of a 2641LF (804m) of 72” (1.8m) storm sewer in 3 No. Drives, 3No. launch and reception Shafts, 3 No. tie-ins. The existing Division Avenue Pump Station (DAPS) 18‐inch force main was proposed to be replaced based on its assumed poor condition (based on the age and material of the force main) and a second force main added as a backup.
