The following information was offered to managers and operators of provincially owned buildings by the Department of Transportation and Public Works as an interim guideline to limit the effects of excessive snow and ice accumulation and excessive floor loads. It is recommended that these guidelines be used until a competent structural evaluation is completed. Guidelines for controlling snow accumulation on roofs 1.Building maintenance staff should visually inspect each roof to monitor snow and ice accumulation. 3.Remove snow accumulations, where high and low roofs meet, and around roof top mechanical units.
Inspect roof drains and ensure drains are working properly.
6.When removing snow from one section of a roof, avoid travelling over and compacting snow on adjacent roof sections. 7.These are interim measures to be taken until you have a structural evaluation completed. A qualified structural engineer may determine appropriate interim precautionary measures that would be more suitable, based on the condition of the structural members and the design snow and rain loads for the location of the building. Guidelines for loading on Floors 1.Assembly areas, libraries and other areas with heavy loads on floors should be inspected. 2.This is an interim measure to be taken until you have a structural evaluation completed.
