UBC Stormwater Detention : Multiple Use Stormwater Detention Adjacent to UBC Centre for Comparative Medicine Tafsir, Ali; Clarke, Peter; Chen, Vincent; Trach, Jillian; Vogler, Chase; Wiebe, Ethan


Our team has been retained by UBC to develop a multi-use stormwater retention system reflecting the need to address the event of a 100 year return period storm. This call to action is as result of of a need to address and prevent cliff erosion off the Southwest Marine Drive and Point Grey area. The system shall be situated adjacent to the UBC Center for Comparative Medicine (CCM) and shall encompass key design criteria as laid out by Mr. Doyle while adhering to UBC SEEDS Department’s criteria to sustainability at UBC. As result, our team is proposing a multi-use Velodrome design to combat the 100 year return period storm whilst also providing an excellent cornerstone for growth within the UBC community. The Velodrome will also be encompassing a park within it as to further push UBC SEEDS Department’s criteria to sustainability and a greener image. The system will limit the outflow to approximately 1.2 m3/s. Additionally, the volumetric capacity will contain 3,400 cubic meters of water and fulfills the BC Water Quality Guidelines for the discharge of water. Given the provided geological data, soil conditions and borehole data, our team has developed a design structure and ensuing calculations to support the development of the UBC Velodrome. Additionally, Issued for Construction (IFC) drawings are enclosed for the construction of this project. Utilizing UBC, Metro Vancouver, Canadian, and other applicable guidelines, the construction processes are identified and a proposed schedule of the entire project is enclosed. Using RSMeans, other notable municipal and federal projects information, and finalized details in our service life and maintenance plan including the time value of money and interest rates, our Class C cost estimate has been updated to a Class B cost estimate. Additionally, our team will include considerations for the service life and maintenance of the UBC Velodrome as well as recommendations for its design.
