| 总结: | Construction resources are fundamental requirement for any construction
project to achieve project completion within estimated budget. The
fundamental construction resources include material, manpower, machinery
and money. These resources have significant effect on construction cost.
Construction cost is now a days facing problem of coverrun. Hence,
it is very critical to assess impact of various resources on cost overrun.
Data collection was carried out using structured questionnaire survey
amongst client, consultant and contractors in southern and central region
of Malaysia. A total of 234 questionnaire were collected including 128 in
southern part and 106 in central part. Data was analysed with PLS path
modelling using SmartPLS v2.0 software. The result showed that resources
have significant effect on cost overrun. Extracted variance showed that in
southern region, around 40% of cost variation can be caused because of
construction resource while in central region variance is achieved as 59%.
Material resource was found as common and most significant resource in
southern and central region. GoF value was achieved as 0.529 and 0.566
for southern and central regions respectively confirming the explaining
power of the proposed path model. |
