Landfill Site Plan (1)
As a junior engineer in a small firm, I was afforded a high-level of responsibility and exposure. This drawing details the engineering and planning completed to develop a closure plan for an existing industrial landfill site in central Alberta.
The design, engineering, and planning of this site built upon the work of a previous engineering firm and required a complex assessment of multiple reports (historical and present), design concepts (historical and present), future site uses, lifespan of the site, and surrounding context (neighbours, regulations).
My work included engineering, sketching, design, collaboration with draftsman and other professionals, as well as site visits and construction management.
Landfill Site Plan (2)
This drawing details cross-sections of the previously described landfill site.
There are multiple layers that must be considered when designing and constructing landfills, including: natural soils, groundwater, engineered soils, engineered textiles, surface water, soil cover material, waste and soil stability, surrounding communities, wildlife, regulations, client interests, timelines, scope and budgets.
Optimized Landfill Base (1)
This drawing shows the elevation of an underlying sand lens beneath a proposed industrial landfill expansion in northern Alberta. The sand layer presents an environmental and regulatory concern as this material transmits liquid readily through the ground, as opposed to other denser soils (i.e. clay). Environmental regulations require a minimum separation between a landfill base and the top of a permeable (sand) lens.
Optimized Landfill Base (2)
This drawing presents a creative design which accounts for the elevation of and required separation from the sand lens. The contours consider adequate drainage to low-points (sumps), adequate clearance from the sand lens, and client interests for reasonable storage capacity.
My contributions to this work included: review of technical and regulatory reports, collaboration with geotechnical engineers and soil scientists, design of landfill, sketching and collaboration with professional draftsman, site visits, and construction management.
