The Mass Timber Demonstration Fire Test Program (MTDFTP) included two series of experiments: the pilot scale demonstration tests in summer 2021 in Richmond, BC [1] and the large scale fire tests in summer 2022 in Ottawa, ON. The series of large scale fire tests on a mass timber structure were conducted to study fire safety during construction, fire dynamics and performance in an open plan office space and residential suites, and influence of exposed mass timber on fire severity and duration.
As part of its research to inform the advancement of safe and innovative solutions across Canada’s construction industry, the National Research Council of Canada (NRC) conducted the technical work and science-based large scale fire tests to support the MTDFTP. NRC was responsible for instrumenting the test structure, setting up fire scenarios and fuel loads, conducting the large scale fire tests, analyzing test data and documenting the results.
This report documents the fire scenarios, fuel loads, experimental setups, instrumentation, measurements and procedure used in the large scale fire tests. The experimental data, results of data analysis, key findings and conclusions are provided in the report.
