Factors Contributing to Physical and Non-Physical Waste Generation in Construction Industry

A Review on Implication of Material Management to Project Performance

“…From positive effects, effective material management has a positive impact on time optimization, cost saving, quality maximization, productivity improvement and waste minimization, [1][2][3][32][33][34]. On the other hand, ineffective material management has negative effects on project performance such as time delay, cost overrun, poor quality, loss of productivity and excessive waste generation [2,8,11,14,[35][36][37]. However, in the context of this paper, the criteria are termed in impartial form namely; time, cost, quality, productivity and waste.…”

“…The insufficient stock of materials lead to idling time as workers try not to exhaust the stockpile or it is worsened by work stoppage [11,41]. Due this shortage, materials need to be reordered and causes longer idling time.…”

“…Without the proper and sufficient equipment, it will jeopardize the satisfactory quality of work done [50]. Similarly, the materials itself also need to be in appropriate quality according to the specification [11,42]. Using the appropriate quality of materials can lead to the satisfactory quality of work, subsequently will be accepted by consultant [36].…”

“…In simple word, waste is a product or material that is unwanted and required to transport out from site [11].…”

“…It is important, because the outcome of every construction projects rely on having all proper resources such as materials, labours, plants and equipment delivered to site at appropriate time [10]. Without proper material management in construction projects, construction projects suffer delays, cost overrun, construction waste and low productivity [11][12][13][14][15][16]. As prior literature reports, among the factors that contribute to poor project performance is due to shortage of materials occur in construction projects [1,12,17].…”
