| Summary: | Current project control system is not capable of initiating effective control actions to
remedy performance shortfalls and overcome the occurrences of project overruns. The
weakness in current system is that it does not evaluate quality performance together with
schedule and cost performances of construction projects to initiate control actions. The
research develops a method for deriving quality measure using material usage data and
integrates the measure in current project control system to determine if project control is
enhanced with the integration.
Current project control system integrated with quality measure is applied in several ongoing
construction projects and it is found to result significant improvement in the
performance of the projects. The combined schedule, cost and quality performances in
v
projects initiated with control actions improved by 54%, 72% and 3% respectively. The
organization’s mean value for schedule, cost and quality performances also improved by
22%, 9.6% and 3% respectively and the standard deviation for schedule and quality
performances reduced by 38% and 62% respectively. The deviation for cost performance
however increased by 3% due to an abrupt leap in the cost performance of a single
project, which was not subjected to control actions.
While performances in projects subjected to control actions improved significantly
projects that were not subjected to similar control had schedule and cost performances
deteriorated by 2.64% and 8% respectively. The substantial improvement achieved in
projects subjected to control actions from using this upgraded control system validates
the research hypothesis that integration of quality measure enhances its effectiveness in
controlling project performance. |
