DIDSBURY - Two of three recent infrastructure projects in town have come in under budget, councillors were told during the recent regularly scheduled council meeting.

In a briefing note to council, administration outlined details of the 15th Avenue stormwater main project, the high school connectivity project, and the Westhill Place sanitary sewer replacement project.

The 15th Avenue project had an original budget of $1,053,594, and came in at a cost of $556,078 for savings of $497,516, council heard.

The project is the first phase of a multi-year plan to install an underground stormwater collection system on the south end of the town’s commercial district.

The project started in later summer and was completed in late fall.

“Contractor recommended an alternate installation method than was asked for in the tender,” the note states. “The installation method required more asphalt to be removed. However, the removal of subcontractors and risk mitigation measures allowed the contractor to self-execute the installation with open cut excavation. 

“To minimize the asphalt repair required we used trench boxes to protect workers installing the infrastructure.”

The high school connectivity project had an original budget of $222,406, and came in at a final cost of $250,689 for a difference of $28,283.

The budget overages were due to two things, council heard.

“Where the existing asphalt was lower than the curb line, additional asphalt was needed and the curb line was approximately 0.5 metres further from the existing asphalt than anticipated at the time of tender,” the note states.

“The installation of the sidewalk resulted in a greater total restoration area at the two ends of the work.”

The Westhill Place sanitary sewer replacement project had an original budget of $94,000 and came it at a cost of $84,126 for savings of $9,874.

Council accepted the three project infrastructure report as information.
