Full Title: Qualifying Tunneling Contractors for Construction of the Rutland Truck Sewer - Ferry Road Combined Sewer Relief - Contract 6

B7.          SCOPE OF WORK

B7.1        The Work to be done under the subsequent Contract shall consist of:
(a)      Coordination of shallow utility relocations with various utilities, as required depending 
upon shaft locations.  Relocation of building sewer and water services depending upon shaft 
locations.
(b)      Relocation of approximately 800 m of 300, 375 and 450 mm combined sewer (conversion to 
wastewater sewer) including manholes and relocation of sewer services.  Temporary relocation and 
bypass pumping of the Ness Avenue Combined Sewer Trunk to accommodate the tunneling work.
(c)      Construction of launch and retrieval shafts.  A maximum of 7 shafts is anticipated 
(including a partial shaft at the transition from tunneled to open trench installation).
(d)      Installation of approximately 1,960 m of 2400 mm Reinforced Concrete Trunk land drainage 
sewer, primarily by trenchless (microtunneling) methods but including up to 250 m of open trench 
sewer near the Assiniboine River where the depth of cover is believed to be too shallow for 
tunneling.
(e)      Installation of associated land drainage sewer appurtenances including saddle type 
manholes along the trunk and the installation of smaller diameter lateral stubs at the Assiniboine 
Avenue active transportation pathway and crossing streets to accommodate future sewer connections.
(f)       Installation of a river outfall, including a short riprap lined channel.  A gate chamber 
is not required.
(g)      Several alternative alignments for the sewer river outfall have been developed and are 
shown as a sketch in Appendix A.  Each alignment has different pros and cons with regards to the 
removal of mature trees and impact to existing park and community facilities.  The selection of 
alignment will be done in consultation with community stakeholders.
(h)      Two alternative alignments have been developed for the upper end of the sewer near the 
extension of St. Matthew’s Avenue.  The selection will be done in consultation with community 
stakeholders.
(i)       Replacement of existing and installation of new catch basins and catch basin leads along 
the route and connection into the new trunk land drainage sewer.
(j)       Restoration of parkland, trees, pavements, boulevards and other features impacted by the 
works.
(k)      A Social Procurement clause will be included in the subsequent Tender. The Social 
Procurement clause may address outcomes around employment of equity groups, skills and training of 
equity groups, or diversity in the supply chain.

B7.2        The Preliminary Drawings attached to this RFQ in Appendix B show the general 
arrangement of the works.  Proponents are advised that the attached information is preliminary and 
subject to final modifications.  A full final set of documents will be issued under Tender 
286-2024B for the final bidding process.

B7.3        The Trunk sewer being installed under Tender 286-2023B shall be installed using 
microtunneling methods.  Minimizing the number of shafts and minimizing the disturbance and impact 
on the residential neighbourhood is an important consideration.
