Abstract:
Rework which is often experienced in construction projects is primarily caused as a result
of poor site management practices mainly contributed in presence of incompetent
knowledge and supervision, poor workmanship, insufficient supervision, improper work
protection.
Recent research has shown that rework is the significant cause for schedule and cost
overruns, quality deviations, poor safety, and client and contractor dissatisfaction in the
building construction industry. Reducing rework is widely regarded as an effective way of
improving construction performance in terms of productivity, cost, schedule, quality and
safety.
The research presented in this paper uses multiple completed building projects to identify
the significant variables that contributed to rework. Rework factors’ identification and
categorization are carried out on the basis of rework performing groups in the design and
construction process and best practices are proposed in considering the stages of design
and construction.
This research develops generalized best practices and checklists, which are intended to
reduce rework by managing construction building projects for the purpose of performance
and productivity improvement. Also, they can enable project managers to better
understand priority areas in the process of site management practices in construction
projects.
