This is a service / maintenance or supply contract in Sherwood Park, Alberta. Contact the soliciting agency for additional information.

The County is commissioning a qualified supplier to develop a holistic stormwater model for the urban service areas of Sherwood Park and Ardrossan. The Deliverables to be provided by the selected proponent (the "Supplier") generally include the following: 1. The Supplier shall provide an accurate representation of the existing stormwater management system while identifying current areas of risk and the probabilities of infrastructure not functioning as designed. o Risk is to be identified using the current design and construction standards as well as looking at how climate change may impact that risk profile in the future; o For the purposes of this project, the existing system to be modeled will consist of SWMF's and connecting infrastructure, and not the minor collection system (unless found to be critical to the overall functionality of the model); o Note: the County is not requiring the simulation or recommendation of improvements. o The model will be developed using information from the Strathcona County Open Data Portal (GIS database), as well as existing as-built drawings and engineering design reports to be provided by the County upon award; o The County currently has a Mike+ (DHI) license for other hydraulic modeling purposes so County preference would be to construct the model using that same software; however, the County will also be open to other software recommendations that may be more appropriate for the purpose and scale of the project; and o Ongoing maintenance of the model would be handled by County staff at the completion of the project. 2. The Supplier shall develop a technical report to provide the following information: o A general summary of the model construction including challenges, missing information, and any assumptions made including model parameters; o A summary of how much model results deviate from design; o A review and update of current Strathcona County IDF curves; o A summary of the existing service levels of County SWMF's including but not limited to: o Service area (ha); o Storage Volumes; o Design rainfall events (based on up to date IDF curves); o Design normal water levels (NWL) and high water levels (HWL); o Freeboard elevations; o Design Release Rates; and o Outlet Structure / Orifice
