Integrated project delivery (IPD) in Malaysian construction industry dealing with waste issue.

INTRODUCTION

The construction industry in Malaysia is currently facing many challenges, mostly related to the process inefficiency and cost ineffectiveness. This could be due to the traditional construction process that being condemned by many scholars with numerous problems and issues. The traditional construction process comprises of the tendering process, designing, constructing and handing over the of the building to the end users. In between these processes, there are some barriers that are decreasing the efficiency of the project. The inefficiency in the project can cause the waste problem in the construction. Waste in construction can be defined as the any incident of the material loses and execution of unnecessary work, which generate additional cost no value added to the product [1]. In this paper waste can be defined as the inefficiency of the construction processes, including the usage of material, time, labour and equipment. To be more precise, waste is the expenditure of effort of the using-up of the resource without any value [2]. Waste can be divided into two categories; unavoidable waste (waste by nature), and avoidable waste (waste by human) [3]. Construction waste can be categorized into two clusters; physical waste and non-physical waste [4].

Figure 1 shows the category of construction waste, this paper will discuss how IPD can generally reduce both of the physical and non-physical wastes in the construction in the following section.

Issues:

Waste can be generated in many ways. In general, there are three types of waste in construction projects; material waste, time overrun and cost overrun [5]. All in all of these three factors will lead to profit losses in the project. That being said, these wastes can mostly be reduced or can be reused in the same project or in another project. IPD could solve most of this issue by implementing nine IPD principals in the construction projects. The American Institute of Architects of California Council line up the nine principles of IPD [6]

Method:

Based on a literature study, this paper will discuss the nine IPD principles to overcome the problems in construction generally focusing on how IPD can reduce waste, where IPD can minimize the cost and maximizing the value of the construction. This IPD will eliminate the barriers in between the people in the construction project.

Discussion:

It is only logical that the bigger construction project creates more waste, and this waste will create more losses in terms of cost, time and other physical waste. In some developed countries in Africa, it is estimated that 40% of construction waste is from rework, 30 to 40% labour and 20 to 25% waste from materials [7]. In Hong Kong, 5 to 10% of building materials will end up as waste [8]. In many countries, waste factor contributes to increasing wasteland congestion and most of the waste will not easily degrade in a short term. Figure 3 shows a classification of waste in construction projects.

According to AIA (2012), the use of IPD in a construction project is capable of reducing waste. The nine IPD principles serve as a guideline in ways that the construction team can interact in order to reduce construction wastes. Table 1 below indicates how the IPD principles can be assimilated into current construction processes that lead to project efficiency and minimizing waste.

From Table 1, it can be seen that by applying the principles of IPD, the interaction of the construction team within the project can lead to reducing the physical and non-physical waste during the construction process. Therefore, the value and efficiency of construction processes can be maximized, as well as reducing the adverse relational problems that is often mentioned in the construction industry in the long run.

Summary:

IPD must be followed through with discipline and punctuality of every party in the construction team or otherwise the system will fail to achieve the promising targets. Integrated project delivery must be initiated in the early phases of project planning, way before the drawings are confirmed for the project. With commitment from owners, architects, engineers, contractors, subcontractors, suppliers and financiers, and continuous effort to IPD from the planning phase to the closing phase, efficiency and cost effectiveness in construction projects will be achieved which leads to minimization in construction wastes.
