Analysing The Malaysian Construction Industry Construction Essay

Abstract The Malaysian construction industry is undergoing a transitional change from an industry employing conventional technology to a more systematic and mechanized system This new system is now known as the Industrialized Building System IBS This new method of construction can increase productivity and quality of work through the use of better construction machinery equipment materials and extensive preproject planning This study becomes very necessary since there is yet no organized body which can provide the necessary information on the building cost comparison between the conventional system and industrialized building system in Malaysias construction industry This study also addresses the building cost comparison of the conventional system and industrialized building system of formwork system It provides the details building cost between the conventional system and the formwork system and indicates which of the two is cheaper The data were collected through questionnaire survey and case study which consisting of institutional buildings Through the statistical test ttest it is shown that there is a significant difference in cost saving for the conventional system as compared to the formwork system industrialized building system

Key words Conventional Formwork System Building Cost Comparison

INTRODUCTION

The Malaysian construction industry is undergoing a transitional change from an industry employing conventional technologies to a more systematic and mechanized system employing the latest computer and communication technologies This is vital for the future health of the industry given the trend towards global competition and the advent of the keconomy

The Industrialized Building System IBS has been introduced in Malaysia since the 60s by the use of precast concrete beamcolumn elements Since the demand of building construction has increased rapidly it is necessary to innovate a construction method which speeds up the building construction process Abdullah et ad 1 has listed the various types of building systems currently available in Malaysia Few definitions of industrialized building system are also given by various authors 2 To sumup in general the IBS is a methodology whereby a local construction industry is driven towards the adoption of an integrated and encouraging key players in the construction industry to produce and utilize prefabricated and mass production of the building at their work sites This will help to enhance the efficiency of construction process allowing a higher productivity quality time and cost saving

The construction cost of a building using precast components should be assessed in its overall context The traditional method of costing by material quantities with a fixed factor for labor cost can lead to incorrect estimation For example if labor usage is halved this will more than compensate for a 10 material increase More importantly there is saving in time Also if properly designed and executed precast can lead to much better quality of work The overall cost impact of precast has therefore to take all these factors into consideration With the rising costs of labor and less assurance of dependable skilled manpower the trend is that precast construction will become increasingly competitive compared to castinplace construction 3

Classification of Industrialized Building System Industrialization The Oxford English Dictionary 1991 defines industrialization as the process of industrializing or fact of being industrialized also the conversion of an organization into an industry However industrialization in this study means industrial methods employed referring to especially prefabrication mechanization and standardization The meaning of prefabricated according to the same dictionary is to manufacture sections of building or similar structure in a factory or yard prior to their assembly on a site However prefabrication in this study is the assembly of buildings or their components at a
