SUSTAINABLE MANAGEMENT OF MULTIPLE D&B INFRASTRUCTURE PROJECTS IN RURAL AREAS OF SABAH

In recent years, the “sustainability” in infrastructure
projects is a mandatory issue to assure long-term ecosystem
functions, as well as enhancing the quality of life in urban /
rural communities. These values will be achieved through the
systematic management of multiple projects developed in rural
areas. Selected infrastructure projects are being implemented by
Design and Build (D&B) procurement system in Sabah (East
Malaysia). In these development projects, 45 Bridges in bridge
replacement projects together with two Road projects are being
executed simultaneously by the author’s Design and Build firm.
The former were awarded in 5 packages in the first phase of
Bridge replacement project for PWD. The latter are constructed
for Ministry of Rural development. The company manages such
projects by using established systems for design, contract,
contract administration, construction execution and supervision.
Engineers from qualified engineering bodies are selected and
appointed for In-house design team / supervision team. Team -
discussion and inputs in selecting critical bridge components
including (i) Methods of pile foundation, (2) Selection of
suitable beam technologies, (3) No. of spans, etc are explained.
Majority of the construction works are executed directly by main
contractor with appointed specialist contractors for piling works
and beam production. The objectives of this paper are to give
solutions for the sustainable management and investigate for
improvement in management of multiple D&B projects.
