Abstract—Traditionally, construction quality control relies
on final inspection and rework if the output is not
fit-for-purpose. However, this reactive approach does not
guarantee compliance with the requirements. By focusing on
checking to completed product, a proactive approach to prevent
poor quality is thus hampered. Studies have shown that poor
quality of key resources commonly results in a number of
production-related problems. The premise of this paper is that
inadequate resources, such as deficient material, will not only
result in unacceptable product quality but also in wasted time
for handling and repair. It investigates the causal relationship
between process input (i.e. resource) and output quality, as the
basis for a pro-active control scheme. A field test was executed
to look specifically at the quality of a prefabricated material,
steel reinforcing bars (rebar), as it relates to its staging for final
assembly. A discussion of correlations between attributes of
input quality regarding rebar and the productivity of placement
will complete the paper.
