Abstract
In construction safety, the traditional cycle of plan-do-check-act is deployed at a macro level in that planning occurs prior to project commencement. Systems are then put in place for project execution, and the check (review) is based on overall project outcomes such as Lost Time Injuries (LTI) etc. that is then used for planning for subsequent projects.

This type of performance review results in relatively long and fuzzy feedback loops. It is postulated that safety performance in construction may be improved by shortening the feedback loop based on a three point performance review within the currency of a project. Effective safety management comprises conformance to management plans and quick management response to problems that occur during the process. Consequently, it was proposed that there should be a continuous review of, and feedback based on, these two elements as well as process outcomes (e.g. recurrence of errors) and accidents (e.g. Lost Time Injuries).

This not only accelerates the feedback, but also provides more in-depth guidance for root cause analysis. This proposal was implemented on two construction sites and data gathered through direct observation and participation, document analysis, and site safety surveys. This paper presents an analysis of the data obtained during the trial.

The case studies show that even when planned activities were being carried out, they were not necessarily meeting their intended objectives. The accelerated feedback resulted in identification of a new performance measure, which in turn led to new arrangements for induction and application of financial penalties.
