The Roberts Bank Rail Corridor Combo Project

The Roberts Bank Rail Corridor (RBRC) Combo Project is a design- build project with three new grade separation structures over an active railway along 192 Street, 54 Avenue and 196 Street in Surrey and Langley, BC. The design phase of the project was completed in September 2012 and substantial completion is scheduled for October 31, 2013. This project will add road capacity in an area that is forecasted to become increasingly congested, providing substantial general traffic relief to nearby corridors such as Fraser Highway and 200 Street. The RBRC Program is a comprehensive package of road and rail improvements funded by 12 partners representing local, regional, provincial, and federal governments as well as private industry. Total value of the program is $360 million. The RBRC Combo Project is considered the single largest engineering project that the City of Surrey has undertaken.

Iskut River Bridge The Iskut River Bridge, a 94 m single-span structure, provides the last vital link to the McLymont Creek run-of-river hydro project owned by AltaGas, located just downstream from their other larger, Forrest Kerr run-of-river hydro project. The design build structure was designed by Barry Gerbracht, P.Eng., of All-Span Engineering & Construction (structural and launch) and Sam Fougere, P.Geo., of BGC Engineering (geotechnical) and constructed by Formula Contractors BC. A large rock cut (approximately 160,000 m 3 ) had to be removed from the south end to facilitate the launching of the girders and to bring the bridge to a suitable grade. The bridge is composed of two 3.5 m deep steel I-girders with a 6 m wide composite precast concrete deck.

Mobile Sulf-IX pilot plant BioteQ Environmental Technologies provided engineering design, construction support and commissioning expertise to develop the mobile Sulf-IX™ pilot plant for field testing sulphate removal. The unit is the culmination of eight years R&D on Sulf-IX™ technology, which provides a low-cost solution for demineralizing high scaling potential wastewater in the mining, power generation and industrial sectors. Sulf-IX™ is a novel use of standard water softening ion exchange resins to mitigate the scaling potential of these process streams. The result is treated effluent meeting discharge or re-use requirements, high water recovery and a solid gypsum by-product. Housed in a standard 53 ft. trailer, the pilot plant is equipped with automatic PLC control and can treat a continuous flow of 10 L/min.
