DescriptionA - Latest Addendum

The ASHC Rundle 1 (RUN1) social housing complex, located at 147 Rundlemere Road NE, Calgary, Alberta, consists of eight (8) blocks of townhouses for a total of 56 units.

The complex sanitary system consists of “unit risers” (internal lines within the units), each connected to a “complex main” (common line under each block). The complex mains are connected via “block services” (line from block limits under parking lot) to the sewer main lines, which convey sanitary flows to the City’s sanitary system. Condition assessment methodology for sewer mains was based on National Association of Sewer Service Companies (NASSCO) Pipeline Assessment & Certification Program (PACP) sewer condition grading. An overview map of the sanitary sewer system is included in Attachment 1.

All eight (8) blocks show some degree of fats, oils and greases (FOG) build-up, with associated water backup due to flow obstruction. The major concern arising from the condition assessment of the RUN1 sanitary network is the heavy build-up of FOG within all of the complex mains and some of the unit risers. The majority of unit risers are in good condition. Since water is backing up in the vicinity of FOG deposits, it is not possible to tell whether the standing water is due entirely to the FOG deposits, or whether there is also an underlying issue with pipe sagging.

Assume three (3) total repairs, each with a 5.0 l.m. pipe section for repair, confined to a single unit basement. Includes concrete slab removal, excavation, pipe repair, backfill, and all restoration work to restore to original basement condition.
