The scope of work associated with this RFQ includes, but is not limited to, the supply of all materials, labour, and installation associated with the Stage 1 Enabling Works Civil scope of work, comprising relocation of existing site services (water, sanitary, and storm services). Some of the services are at depths of approximately +/-4m below grade and cross beneath buried service tunnels. The reinforcement and waterproofing of the buried tunnels will form part of a separate RFQ. Natural gas services will be relocated concurrently by Enbridge and will necessitate time and space separations for the completion of the work. A high-level overview of the work to be performed is as follows - note the scope and quantities below are subject to change, pending the issuance of the RFP:
