Northeast Ohio Regional Sewer District Stickney Creek

This project will protect the District’s Ridge Road Intercommunity Sewer which has become exposed due to erosion caused by Stickney Creek, part of the regional stormwater system. The project is approximately 750 feet long and is located east of Ridge Road between Biddulph Road and West 66th Street in the City of Brooklyn. Severe erosion of the creek bed and banks have exposed approximately 175 feet of the 66-inch brick sewer, which created the potential of combined sewer discharges into Stickney Creek during high inflows.

This project alleviated the threat to the sewer rehabilitated and stabilized the creek and improved natural stream functions. NEORSD determined the best way to reconstruct the sewer and stabilize Stickney Creek was to employ a progressive Design-Build approach. Weekly meetings during the pre-construction services period allowed our team to listen, provide economical technical feedback and IGMP estimates at the 30% and 60% design stages to validate the Owner’s budget for the project.

The deteriorated 66-inch brick sewer required complete replacement and, with Independence Excavating’s input, the team lowered the project costs by having our engineering consultant design a 72-inch diameter RCP with precast bends in the sewer run, in lieu of a junction chamber or large manhole. In areas where access to the 72-inch sewer was required, they designed an in-line precast tee in lieu of a manhole.

Additional cost savings were realized because all precast elements were pre-fabricated off-site and delivered to the site when needed, eliminating the need for additional staging area required by the originally-scoped cast-in-place elements. This also prevented delays in the sewer installation. This unique project delivery system had the complete support and buy-in from NEORSD and our team that delivered the project under the GMP and ahead of schedule.
