Key Project Terms: Sidewalk Shed (Construction Equipment)

The following is a list of useful terms to use when researching additional Sidewalk Shed information on each of the topics discussed:

BSA Approval Minutes

The approved Board of Standards and Appeals (BSA) standard design of sidewalk sheds that can be used, and which are referenced on submitted drawings, in lieu of a registered design professional’s seal and stamp on the submission.

Cross Bracing

Additional bracing that forms a cross shape to keep the columns plumb and square.

Heavy Duty Sidewalk Shed

A sidewalk shed designed to carry a load of at least 300 pounds per square foot.

Junior Beams

Unlike the main steel beams, junior beams span in between the main structural elements, similar to joists.

Light Duty Sidewalk Shed

A sidewalk shed designed to carry a load of at least 150 pounds per square foot.

Load Effects (sidewalk shed)

Forces and deformations produced by the applied loads in the structural members of the sidewalk shed.

Main Beams

Material (for construction of the sidewalk shed)

As required by BC Chapter 33, sidewalk sheds shall be constructed out of wood, steel, or similar materials which possesses equivalent strength and suitability.
