City of Calgary - Invitation to Bid - 24-2042-S11 (SOR 11) CPKC Rail Crossings Water Mains Upgrade

The Watermain Extension Program was created to improve the existing water system for better connectivity and looping. This program provides the following benefits: • Improve fire flow for existing areas • Reduce/mitigate water quality concerns • Improve the system design to meet current design standard • Establish better water network for future redevelopment, and operational considerations This program identified two watermain upgrades that includes the crossing of Canadian Pacific Kansas City (CPKC) track/RoW (Righ-of-Way). The upgrade projects are on 15 St SE between 9 Av SE & 20 Av SE (hereafter referred to 15st). This project also includes a water main upgrade and storm drainage upgrade on 19 Av SE. The second project is a water main upgrade on 26 Av SE at Dartmouth Rd/Highfield Rd SE (hereafter referred to Dartmouth Rd). For both projects, due to the geotechnical conditions, the crossings of the CPKC RoW will be completed using Horizontal Hammer Boring of a 750mm diameter steel casing with the installation of the carrier pipe within the installed casing. All other work on the projects will be with open cut construction.
