Abstract
For many years now delays, reworks and reVISIOns have weighed down the
construction industry in South Africa. There have been several attempts to minimize
this problem, but none has managed to comprehensively manage this scourge and it
looks as though the situation has come to stay. This study takes a look at some of the
supposed causes of delay, rework and revision found in the literature in the light of
their characteristics and influence. The data is drawn from a questionnaire survey of
forty three construction industry professionals practicing in South Africa. Using a step
mUltiple regression analysis, T -Test analysis and relative importance index to
determine the major causes of delay, rework and revision. It was found that change
related issues and approval related issues were amongst the foremost factors causing
delay, rework and revisions. The study also found problems of inadequate design
coordination tools, poor information technology, inadequate change management
structures and systems, and poor scope definition to be significant problems facing the
industry.
