In December, 2007 the City of Prince George experienced a rapid cold snap which resulted in an ice jam on the Nechako River. A 66-day long local state of emergency was declared and over 100 residents were evacuated from their homes.
Since 2008, McElhanney has completed over 300 assignments for Parks Canada. This includes emergency response services for major floods in Banff, Jasper, and Kootenay National Parks in 2012 and 2013, as well as avalanche cleanup in Banff National Park in 2017.
Following severe rain in June 2011, Hwy 97 experienced floods between Pine Pass and 20km south of Chetwynd (a length of 60km), with 73 damaged sites. This flooding resulted in the loss of culverts and bridge end fills, and washouts along various portions of the highway, forcing closure of this vital route.
During the summer of 2017, BC Hydro’s 60-year old creosote timber dam was completely removed from the Salmon River on Vancouver Island, and the site was re-naturalized. McElhanney designed bypass channels, cofferdams, and river diversion works to use as small a footprint as possible in this narrow and hectic worksite.
McElhanney provided surveying services to aid renovations at the library. The objective of the survey was to identify a precise location for a temporary concrete platform supporting a multi-storey crane, and to identify positions to underpin and support the load of the crane and platform.
The Warman & Martensville Interchanges or Overpasses located on Highway 12 at Martensville and Highway 11 at Warman, will improve safety for two of the fastest growing communities in Saskatchewan.
McElhanney was retained by Parks Canada Agency to provide the following services: roadway and surfacing design; geotechnical and materials testing; drainage review and design; utility coordination; integration of bridges, lighting, signing; construction administration; road safety audits and upgrades; and surveying.
TransLink and the Ministry of Transportation and Infrastructure brought on McElhanney as the prime consultant to address deck repairs and create both a traffic management plan and an operations plan. The result was comprehensive plan that allowed the bridge deck rehabilitation to be completed and re-opened ahead of schedule.
During construction, more than 120,000 vehicles drove over the Port Mann Bridge every day, ranging from commuters (travelling 80km/h) to slow-moving construction machinery. The detour designs needed to incorporate HOV lanes, cycling lanes, and dedicated bus and truck ramps, and ensure high-speed and low-speed traffic did not mix.
The Town of View Royal’s sanitary sewer master plan was last updated in 2005. Since then, the region has undergone significant growth, and their plan and systems need to be upgraded. Currently their sanitary sewer system is comprised of a gravity collection pipe network and 17 pumping stations. View Royal hired McElhanney to update past system models to reflect current operating conditions, to assess existing system conditions and service life, and prepare a capital plan list to help the town prioritize short-term and long-term upgrades.
