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.
McElhanney was hired to update View Royal’s sanitary system models to reflect current operating conditions, assess existing system conditions and service life, and prepare a capital plan list to prioritize short- and long-term upgrades.
McElhanney successfully value engineered an extradosed segmental bridge concept with 16 back-to-back 120m-long spans for the 1,920m navigation spans portion of the 4km bridge. Approach spans outside the navigation spans utilizes precast segmental erected in span-by-span.
McElhanney developed six options for Upland’s separate sewer and stormwater systems with service to each residence. The District is focused on eliminating combined system overflows and reducing overall volume to the regional system.
