Reconstruction of Trevithen Street, Alexandra Street and Herkimer Street in London, including the replacement of all underground sewers and water infrastructure for a length of approximately 1200 metres. This project also includes the construction of a storm sewer outfall, with channel excavation and landscape work. A major challenge on this project is the space limitation given the depth of the proposed sewers. A temporary water supply system was used to partially address the space constraints during construction of the new sewers and 200mm and 150mm diameter watermain.
Construction of a sanitary trunk sewer across Medway Creek and along Sunningdale Road West, for a total length of approximately 1625m.
The path of the sewer includes a section through the environmentally sensitive area of Medway Creek and includes clearing, grubbing and earth excavation in the valley. A crossing of Sunningdale Road will be accomplished through jacking and boring. Crossings of Medway Creek in three locations will require temporary bridges. Supply and installation of sand bleeding wells are required for the release of water pressure at the bottom of the sewer trench. The disturbed areas in the valley will be properly restored at completion and will include pedestrian pathways.
Construction of new potable water pumping station and reservoir, for storage of water pumped from Lake Erie into London. Includes the topsoil stripping and cut/fill to the entire site, excavation and backfill for the reservoir and pumping station, installation of new storm sewer complete with structures and headwalls, placement of granulars for all paved areas, construction of landscape areas and rough grading of a bike track.
A project for Parkwood Hospital, included the mass excavation, bedding and backfill for a new steamline, condensate line and hydro ducts complete with pullboxes. This also included the excavation, base and placement of two new cast in place chambers which are attached to the hospital. Working for the General Contractor, the job required careful excavation and precision care when working around the installed steamlines.
This project consists primarily of a realignment of an existing storm water channel. Because of the space restrictions, it requires the construction of a sheet pile shoring wall against an existing Environmentally Sensitive Area. A number of structural retaining walls will be constructed, some out of Rosetta Wall, some out of armour stone. Concrete works include a concrete lined channel, a prefabricated pedestrian bridge and extensive sidewalks and pathways. The project will also include electrical installations, site furniture and an elaborate landscape plan.
