British Columbia, Canada
Norwest’s geotechnical group was hired to perform initial site investigations and develop permit-level geotechnical designs for a tailings dam, coarse coal reject (CCR) pile, a large rock drain, and waste rock dumps for a coal project in Northeast British Columbia. Subsequent work included additional site investigations to support a mine permit amendment based on an increased coal production schedule. Upon permit approval, Norwest was engaged to provide detailed geotechnical designs, prepare tender packages, develop Issued For Construction (IFC) drawings, and provide on-site construction management for the initial starter dyke construction.
Norwest has been actively involved with this project since its inception and has developed IFC drawings and provided construction management for the expansion of the tailings dam and CCR pile underdrain system. Norwest has been responsible as the engineer of record to perform annual dam safety and waste rock dump inspections and create annual inspection reports that are submitted to the Ministry of Energy and Mines as per regulatory requirements.
Working closely with the client to successfully meet their needs over the past 10 years has allowed Norwest to perform tailings storage option studies, develop a site wide geotechnical monitoring program, provide on-going operational support, and the execute numerous geotechnical site investigation programs.
A client expanding their existing mine operations required support for a major earthworks project in northern Alberta.
Norwest was engaged to provide the detailed engineering design, prepare tender packages, review bids, develop Issued For Construction (IFC) drawings and provide on-site construction management. The work was conducted over a 10 month period and involved the excavation of approximately 10 Mbcm of material as well as the construction of the supporting infrastructure and road network.
The project was successfully completed within the tight timeframe through planning by all parties to ensure production was not compromised and that a safe working environment was maintained.
Project Development Support
A client with significant resource holdings was looking to develop the project and obtain regulatory approval to construct a mine. The project is green-fields, minimal resource information is available and mine planning has not been conducted to date.
Norwest was engaged to begin resource delineation drilling. For the following 3 years, Norwest plans and manages the exploration, geotechnical and hydrogeological drilling programs along with data management and geological model construction. Upon receipt of the model from the first year of drilling, Norwest’s mine planning group begins preliminary life of mine development options and engineering design. Subsequent drilling programs provide additional data, which allows engineering design and cost estimating to proceed to a prefeasibility level in support of the regulatory application.
Norwest’s ability to supply integrated field support, geological, geotechnical, hydrological, data management and engineering design services improves execution efficiency and reduces project costs.
