The Work generally comprises of:

The delineation and re-grading of the Northwest Drainage Channel, the installation of gabion rock riprap drop structures, followed by the supply and placement of Class 1 rock rip-rap and geotextiles, Pyramat 25 Turf Reinforcement Mat, Pyramattress, Scourlock, and seed (hydro-seed). Approximately 9,600m2 of Pyramat 25 Turf Reinforcement Mat, including the associated pins and washers, will be supplied by the Owner as outlined within Section 00 30 00 – Available Information.

The delineation and re-grading of the Northwest Drainage Channel is required along the existing Northwest Drainage Channel alignment from the Canadian Pacific Railway crossing south of 57 Street to the Brekko Lake Storm Water Management Facility to improve the systems overall capacity and repair eroded areas. The project Site will consist of two (2) locations, one (1) location southwest of the 57 Street crossing, and one (1) location northeast of the 57 Street crossing. The Work will include vegetation grubbing and disposal, topsoil stripping and stockpiling, excavation to the design subgrade elevation including loading, hauling, moisture conditioning, and placement of embankment clay fill (Approximately 2,200m3), as well as the loading, hauling, moisture conditioning and placing of import clay fill (Approximately 500m3), drainage channel contouring and compaction, and the supply and installation of rock rip-rap and gabion rock rip-rap drop structures at select locations. The excess clay fill generated from the delineation and excavation of the Northwest Drainage Channel will be either disposed of at the City of Lloydminster Landfill or placed on site as clay embankment. Upon completion of the delineation and excavation of the Northwest Drainage Channel the Work will include the placement of owner supplied Pyramat 25 Turf Reinforcement Mat (Approximately 7,900m2), supply and placement of Pyramattress (Approximately 400m2), supply and placement of Scourlock (Approximately 265m), and the placement of owner supplied topsoil.

The Northwest Drainage Channel is an active storm water drainage channel and as such water management and water control will be a key aspect of the project.
