Scope of the project was to place two individual classes of aggregate to a total depth of 2.17 meters for the total length of the 2000 lm of bored tunnel.
1.3km of 3-4m wide paved pathway including gravels, grading and 3 lock-block retaining walls. Main challenge was working between Highway 97 and Okanagan Lake in limited space with midsummer tourist traffic.
Construction of 40,000 m3 Earthen Flood Dyke, installation of sheetpile flood wall, relocation of existing utilities. Emergency access from Mary Hill Bypass including 12,000 m3 of Granular fill, an open bottom Arch culvert with Retaining Wall. Many difficulties presented themselves on this project, the most prevalent were sourcing and placing specified dyke fill material, driving plastic sheet piles into heavily consolidated ground plus working in and around a heavily secured facility.
A brand new 4 direction interchange was constructed on HWY 99 at 16th Avenue. The project required the relocation of Ferguson and Carlson Creeks. Two pre-cast panel walls were required for north and southbound off ramps, the later requiring a curved wall. Property acquisitions were untimely so a temporary stream channel had to be constructed to bypass an entire portion of the project site for several months. The project was completed 2 months ahead of schedule.
A new offramp was constructed to provide direct access to the Boundary Bay Airport via HWY 99 Southbound. The Ladner Trunk Interchange also required some interim upgrading to facilitate an acceleration lane for HWY 99 Northbound. This required shoring of the north abutment fill slope and preloading of all new construction with about 35,000m3 of preload. This project was completed on schedule.
The objective of the works was to create northbound and southbound passing lanes on 2.80km new alignment with the existing highway becoming frontage road. The major work carried out on this project is: - 25,000 cubic metres of excavation - 19,000 cubic metres of gravel - 17,500 tonnes of paving - 2.4 km of roadside cable barrier Other components of this project include Quality Management, Environment Management, drainage, signage and intersection lighting.
On March 25, 2011, Hall Constructors was awarded the contract to perform slope stabilization works above the spillway at BC Hydro’s WAC Bennett Dam near Hudson’s Hope, BC. This project will consist of blasting and excavating over 230,000 cubic yards of rock as well as installing anchors and shotcrete on the final slopes above the spillway. Upon completion of the blasting, protective rock mesh will be installed to further minimize the possibility of rock fall. This project was completed in November, 2011.
Highway widening and intersection improvements including 1,500m2 of retaining walls, 36,000m3 of excavation, drainage and sanitary sewer works, street-lighting and signalization.
