Widening and rebuilding a main Ottawa thoroughfare

Improving transportation infrastructure in Ottawa.

The City of Ottawa is widening a 2.5 km segment of Bank Street south of Leitrim Road from two to four lanes, including a raised median and modifications to signalized intersections complete with sidewalks and bike lanes. The reconstruction project will include installing and/or replacing linear infrastructure including watermains, storm sewers and sanitary forcemains, as well as culverts at stream crossings.

Thurber was the geotechnical, environmental, pavement, and hydrogeological consultant on the project. We provided pavement, subsurface, and bedrock investigation, and excess soils re-use assessment. We also provided a thorough hydrogeologic investigation of water taking and discharge requirements which included a pumping test program with monitoring at 25 locations, groundwater sampling, long-term groundwater level monitoring, a private well survey, and in-stream surface water monitoring. Our deliverables included an Assessment of Past Uses (APU) Report, a Sampling and Analysis Plan (SAP), a Geotechnical Investigation Report, a Pavement Structure Reuse Assessment, a Soil Characterization Report (SCR), a Materials Management Plan, a Pumping Test Design Report and Discharge Plan, and a Hydrogeological Investigation Report in support of a Permit to Take Water.
