UBC Stormwater Detention : Detention Facility for UBC CCM

University of British Columbia. Campus and Community Planning

The TTG Consulting Ltd. has been contracted with UBC Social Ecological Economic Development Studies (SEEDS) Sustainability Program to design a detention facility for UBC Center for Comparative Medicine (CCM). By following the requirements of the client and the Integrated Stormwater Management Plan (ISMP), a detention facility will be developed adjacent to the UBC CCM. The purpose of building this facility is to minimize the erosion of the surrounding cliffs, eliminate the flooding concerns due to large storms, and improve the quality of stormwater leaving campus. The final design includes a 100m*50m*4.5m detention pond and a 3-story multi-functional green building. This report summarizes the design progress and critical outcomes after the preliminary design. Some of the highlights are as follows: the detention pond storage capacity is 20700 m^3; the 100-year pre-development rainfall flow rate is 1579 L/s; the walls of the building will be constructed of large panels of glass; the building’s first floor is designed to be completely submerged underwater; there is a 265.25-m^2 transparent solar panel installed onto the building; the total retainable floor area of the building is 1162.25 m^2. More details can be found in the attached report. The total cost estimation of the whole project is $4.4 million which includes $0.4 million of environmental protection and permitting cost, $1.6 million of detention pond system construction, $1.3 million of building structure construction and $1.1 million of operation and maintenance cost combined with contingency cost as well as GST and PST in BC. The project will be constructed on May 1st, 2019, and the substantial completion will be achieved on May 11th, 2020, with the full operation coming up on Aug 6th, 2020.
