The District of Squamish and Squamish Nation recently partnered in the preparation of an Eagle Viewing Area / Siyich'em Reserve Dike Master Plan (DMP) which identified a preferred option for upgrading the Squamish River dike in the area. The dike at this location protects contiguous District and Nation lands throughout the heavily-developed Upper Squamish River floodplain.  The existing structure is subject to a number of technical deficiencies and does not have land tenure over Squamish Nation reserves.  Through extensive discussions, the DMP identified a preferred upgrading option that would re-align the dike to protect and potentially reclaim historic reserve land cut off by the existing dike alignment. This project will include a geotechnical investigation and seismic assessment of the Squamish River Dike to support proposed upgrades. Work will include drilling boreholes, completing seismic stability analysis and determining ground improvement requirements for the proposed dike upgrades. The project will also assess logistically-difficult erosion protection requirements for the dike based on the District's hydraulic river model and prepare a conceptual design for erosion protection works. Based on seismic and erosion protection requirements, the successful proponent will update the conceptual design for the dike upgrade as well as the associated cost estimate. The resulting design will provide the basis for preliminary permitting discussions with the BC Inspector of Dikes, which in turn will confirm regulatory feasibility and pre-requisites of the preferred diking option. The District would like to retain a qualified consultant to complete these studies and develop a concept design and cost estimate.

The objective of this Request for Proposal (RFP) is to provide assist with budget planning and refine the concept design to inform the future detailed design of dike upgrades. It is the District’s intent to select a preferred proponent based on the evaluation criteria outlined in this document.
