Keywords: Engineering, management services

BGC Engineering offers comprehensive services in hazardous site management ranging from initial site characterization through remedial action design, implementation, and post- implementation monitoring. The firm also has extensive experience serving as a client liaison to regulatory agencies, and developing and implementing strategies to lead the project throughout the complicated regulatory process.

BGC staff have investigated contamination in all media: soils, sediments, groundwater, surface water, and air. Contaminants present at these sites have included metals, volatile organics, and other organic compounds such as pesticides, PCBs and petroleum derivatives. Our highly trained professionals have studied abandoned waste sites, landfills, hazardous waste disposal facilities, mine sites, manufacturing and industrial complexes, and military bases. These sites range in size from under five acres to over 75 square kilometers.

Remedial measures evaluated and employed by BGC include:

Aquifer restoration, including groundwater extraction, treatment, and re-injection.
Physical and hydrologic barriers, including slurry walls, sheet piles, and well pumping for groundwater low containment.
Engineered covers and caps.
Complete or partial excavation and disposal at existing or on-site engineered and permitted landfills.
Developing conceptual designs
Surface-water contamination remediation, including source removal, channel modifications, isolation from other surface water systems, and dredging contaminated sediments.
Gas collection and abatement systems.
Venting of volatile organics in soils.
Waste treatment, neutralization, and fixation.
Incineration of solids and liquids.
Leachate extraction and treatment.
Alternative water supply and/or institutional controls.

Management services provided:

BGC provides comprehensive design services from alternative analyses to final plans and specifications. Remediation design plans and specification packages have addressed hydrocarbon losses at petroleum retail outlets, active and inactive oil and gas facilities, mines, railway yards, and industrial facilities.

Our groundwater remediation services incorporate removal of phase-separated hydrocarbons and extraction, treatment, and disposal of groundwater containing dissolved constituents.

Treatment technologies include air stripping, activated carbon, air sparging, and bioremediation. In response to local air quality ordinances, thermal incineration/catalytic conversion and vapor phase carbon technologies can be used to treat the off-gas from air strippers.
BGC services include excavation, treatment, disposal, and/or in situ remediation of contaminated soil. Aeration, land farming, and rotary kilns are used to treat excavated soil. Bioremediation and vacuum extraction are two important in situ technologies.

Our professional engineers and technical support staff procure material and manage excavation and mechanical contractors to assure construction activities are completed on time and within budget. With in-depth experience in this area, our staff ensures that the constructed remediation systems comply with final plans and specifications.

BGC's remedial action services include:

Heavy Civil / Foundation | BGC Engineering

Geotechnical earthquake engineering is one of BGC's areas of technical expertise and our involvement has commenced at the initial stages of seismic hazard assessment where we have interacted with seismic hazard specialists to define levels of seismic shaking required to provide acceptable engineering solutions.


Services | BGC Engineering

BGC has coordinated environmental impact statements, provided liaison with regulatory agencies and prepared containment and control reports for regulatory authorities, and has participated in the preparation of Association of Professional Engineers and Geoscientists of B.C. practice guidelines.


Geohazard Analysis | BGC Engineering

BGC has staff members that are experts in Quaternary studies and dating methods, we use a variety of methods to date geohazards including air photograph interpretation, radiometric dating of organic materials in test pits, and dendrochronology.


Water Management | BGC Engineering

BGC has assembled a team of water resource engineers, hydrologists, fluvial geomorphologists, and hydrogeologists that help our clients plan and execute solutions that fit their specific project needs. The integration of traditional engineering approaches with fluvial geomorphology and hillslope processes is a critical component of our evaluation of rivers and their sediment transport regimes.


Permafrost Engineering | BGC Engineering

In addition to the obvious harsh climates experienced in cold regions, northern and permafrost engineering requires that designers be cognizant of the remoteness of sites, the limited construction and shipping seasons and the robustness required for these locations.


Geotechnical Engineering | BGC Engineering

The selection of an optimal location, and subsequent design of key infrastructure, impacts on overall project risks and economics; our approach is to optimize the alternatives for the big-picture by thoroughly understanding the site. BGC's mining and geotechnical engineers are reputed for their common-sense science based approach and have delivered innovative, practical, and cost-effective solutions to our mining clients.


Risk Management | BGC Engineering

BGC staff have extensively published on various aspects of risk assessments and have introduced quantitative landslide and flood risk assessment methodologies to municipal and provincial governments in British Columbia. BGC provides a complete range of Risk Management Services to the mining, transportation, oil & gas, forestry, and development industries.
