Aquarius Gold Mine

Aquarius Gold Mine is a proposed open pit mine and mill complex covering a total surface area of three km2. De-watering the open pit using traditional methods was not the best option, so exp recommended an artificially frozen earth cut-off wall surrounding the open pit to best minimize inward groundwater seepage into the pit during dewatering and mining operations. The frozen earth cut-off was 3.5 km in length and extended to depths of up to 135 m, making it the largest and longest artificially frozen earth wall ever built. We managed the project and provided consulting services for this project.

Project name :

Canada's Malting Co. Silos

Client :

Toronto Waterfront Revitalization Corp.

Location :

Toronto, ON, Canada

Canada's Malting Co. Silos

This malting facility was originally built in 1928. The site had been abandoned for more than 20 years, incurring significant water infiltration to 29 malting silos and a germination/kiln unit. The resulting water damage required a comprehensive structural assessment before opening the adjacent grounds to the public as part of the city of Toronto's waterfront revitalization efforts. Our team prepared a comprehensive building condition assessment to establish the status of the silos and other buildings on site noting any potential areas requiring rehabilitation and/or upgrades. In addition to standard engineering principles to define work required to the facility, we also designed a lowering video camera apparatus to conduct remote inspection of the interior walls and related structures.

Project name :

Krill Oil Extraction Plant

Client :

Neptune Technologies & Bioresources

Location :

Sherbrooke, QC, Canada

Krill Oil Extraction Plant

Exp performed preliminary and detailed engineering of a process for producing krill oil (omega-3) by solvent extraction for the pharmaceutical and nutraceutical markets. Oil production had to be performed in an environment that complied with health, safety and industry standards. The project also involved the design of a clean room, an anti-explosion room, a chemical warehouse and the storage of 30,000 liters of flammable solvent. We provided civil and structural engineering, process engineering, building mechanics and electrical, instrumentation and automation pre-operational verification, and commissioning services.

Project name :

Molson Brewery Plants

Client :

Molson Brewery

Location :

Montreal, QC and Edmonton, AB, Canada

Molson Brewery Plants

The project objective was to pinpoint energy savings measures that would generate a three-year return on investment through an audit of Molson's ammonia refrigeration systems via an analysis of critical and/or high energy consumption processes. We provided: design, specifications and drawings for new ammonia cooling towers and pumping stations and high performance evaporators; layout and piping diagrams for large oil separators; and control philosophy for the compressor control room, based on new discharge and suction pressures and liquid ammonia flow rates.

Project name :

Taylor Steel Plant

Client :

Taylor Steel Inc.

Location :

Hamilton, ON, Canada

Taylor Steel Plant

Exp was the prime consultant on this project, providing architectural, structural, mechanical and electrical engineering services for this state-of-the-art, 180,000 SF steel coil storage facility. It was designed to handle a heavy volume of steel coil product and is equipped with large, high-speed, automatic overhead doors and eight, 45-tonne overhead cranes with a hook height of 28 ft. Four large, direct-fired, continuously operating, exterior heating/ventilating units maintain a constant positive pressure within the building. Very tight dew point and temperature control is required for the storage of "Class I Automotive" steel coils. Due to the large volume of truck traffic, CO and NO2 gases are also monitored and ventilation provided.
