. 2013 PROJECT HIGHLIGHTS

2012

Landfill Management Lapointe Engineering was retained to manage an industrial landfill with a design capacity of 961,000m 3 , located in Northern BC. Coordinating with the engineer of record and the landfill operator, Lapointe Engineering is charged with ensuring that operations are implemented in compliance with the design, operations, and closure plan. The design involves progressive closure including a geomembrane

liner to minimize leachate generation, surface water management, erosion control and site stability upgrades. Due to the proximity to environmental receptors, an environmental effects monitoring program consisting of surface water and groundwater sampling and benthic and fish assessment ensures that environmental impacts are kept to a minimum. With the support of the Ministry of Environment and stakeholders, landfill operations are carefully and consistently monitored to ensure compliance with environmental permits and regulations. Prime contractor: Hoban Equipment. Project management, construction safety management and construction coordination: Lapointe Engineering. Environmental consultant: SNC Lavalin Group.

Water Treatment for Reuse Dawson Creek suffered from shortages of potable water due to a limited supply and recurring drought. Meanwhile, the oil and gas industry was consuming increasing amounts of drinkable water. In 2003, 1% of Dawson Creek’s water supply was used by the oil and gas industry. By 2011, almost 16% was consumed by natural gas extraction. The city partnered with Shell Canada to build the plant, which treats effluent so it can be reused by industry. By creating a supply of reused water, the city has guaranteed a plentiful supply of water for both residents and industry. MHPM was Dawson Creek’s project manager for the planning, design, procurement, and construction of the treatment plant. The plant officially opened last fall, and the City of Dawson Creek, won the BC Water and Waste Association’s 2013 Excellence in the Water and Waste Community Award for the project.

Meridian Beach Pedestrian Bridge

Spanning a canal opening onto Gull Lake, this concrete pedestrian bridge is a reproduction of an antique bow-string truss and is installed at Meridian Beach in central Alberta. The bridge trusses were formed and cast on the ground and post-tensioned. They were then carefully lifted into place with a 120-ton crane, and the deck beams and deck were cast in place. The bridge span is 96 feet with a 10-foot deck. At just over $175,000 including approaches and abutments, this decorative bridge was much less expensive than a more traditional steel pedestrian bridge. Conceptual design: W. Norval Horner, P.Eng. Structural design: Williams Engineering (Colin Campbell, P.Eng.)
