The general risk reduction benefit is through the systematic identification of potential hazards. Moreover, safety planning in construction is often a fragmented process during the project execution planning phase and involves different project personnel. This can present issues in communications and create difficulties for safety engineers to perform accident prevention analyses and recommend appropriate safety measures. Thus, BIM has the technological advantage to streamline communications as well incorporate safety checking over the entire course of the construction project to facilitate safety planning. For example, through clash analysis in BIM, the risk of human error can be minimized by defining where and when fall prevention bracket should be in place to support the scarfold working platform.

The horizontal spacing between
the steel brackets should not be
larger than 1.3 m

7. IS THE SUPPORTING
BRACKET IN THE RIGHT
POSITION?
Is it fulfilled the safety requirement?
Can it be installed?
Will it obstruct the other works such as installation of fascade,
windows, drainage pipes etc.

• The bracket is not installed in that
specified position
• The bracket may be taken off by
other trades when they do their
works
• Even the bracket may be re-
installed back after the works, but
it may not according to the safety
requirement.
