Abstract

In recent years, the “sustainability” in infrastructure projects is a mandatory issue to assure longterm 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 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. 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 the 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. Keywords: Sustainable construction, Multiple projects, Design and Build and Specialist works.
