Windley Contracting Ltd. has been awarded a $412,028 contract to relocate the sewer line at the Regional District of Nanaimo landfill.

The line is currently located on landfill property and according to Larry Gardner, regional district manager of solid waste, it will be moved to a right-of-way on Cedar Road. Windley was awarded the tender as its bid represented the lowest out of all proponents.

Work will require deep excavation, including blasting to remove a significant amount of rock. A $50,000 contingency will be available to cover any unforeseen issues

“All we did in the report to the board was just to advise them that because of the complexity with this project, there’s some added risk and we’re just identifying that there is the potential for cost overruns, because there are some things we don’t know, but what we believe is that we don’t anticipate them to exceed that $50,000,” Gardner said.

George Hrabowych, project manager with Herold Engineering Ltd., who acted as consultant to the regional district, said the blasting is standard and will be done to create a trench.

“Generally it’s a deep excavation, it’s about eight metres and there is in places, seven metres of rock, so [Windley Contracting] will be employing a blaster and all work is done in accordance with industry standards, B.C. regulations and [WorkSafe B.C.],” said Hrabowych, adding the impact on traffic on Cedar Road will be minimal.

“The only implication is it will stop traffic,” Hrabowych said. “Before they blast there will be a two-minute warning and the thing will boom and [they] will let traffic go again.”

Construction is expected to begin on Sept. 15 and last 17 weeks.
