“…In line with existing studies (Ballard and Howard, 1997;Al-Hajj and Hamani, 2011;Marinelli et al, 2014) The JIT is a pull system of procurement, where materials are ordered as at when needed during the construction process. It is different from the push system, where materials are ordered in bulk, leading to over-stocking of materials and longer period of onsite storage.…”

“…This helps in reducing the length of time the materials are stored as well as eliminating the likelihood of over-ordering and double handling, which usually results in breakages (Dainty and Brooke, 2004). Another key benefit of the use of JIT delivery system is its likelihood of preventing double handling of materials, which is a known cause of materials breakage and subsequent waste generation (Al-Hajj and Hamani, 2011). Equally, JIT is a very valuable measure in confined sites, where there is no adequate space for materials storage.…”

“…Based on various identified causative factors, total waste generation in construction project is caused by series of inter-related factors ranging from design stage, through procurement, to the actual construction stage (cf. Lau et al, 2008;Al-Hajj and Hamani, 2011;Esin and Cosgun, 2007;Formoso et al, 2002;Gamage et al, 2009;Kofoworola and Gheewala, 2009). Although the actual waste is generated on-site during construction activities, a number of preliminary factors contribute to its occurrence.…”

“…Notwithstanding the advancement in construction waste management research, most efforts have been concentrated on construction stages (Cha et al, 2009;Begum et al, 2007;Al-Hajj and Hamani, 2011). Lately, research into waste efficient design and impacts of design on waste is also gaining popularity (cf.…”

Although construction waste occurs during the actual construction activities, there is an understanding that it is caused by activities and actions at design, materials procurement and construction stages of project delivery processes. This study investigates the material procurement and logistics measures for mitigating waste generated by construction activities. In a bid to explore the phenomenon from the perspectives of experts from the construction industry, this study used a combination of descriptive interpretive research and survey approach as its methodological framework.The study suggests that four features characterised waste efficient logistic and procurement process. These include suppliers' commitment to low waste measures, low waste purchase management, effective materials delivery management and waste efficient Bill of Quantity. In addition, the key requisite strategies for mitigating construction waste through materials procurement include commitment to take back scheme , procurement of waste efficient materials/technology and use of minimal packaging. The use of Just-in-Time (JIT) delivery system and prevention of over ordering are also important for mitigating waste through materials procurement processes. These implies that while the key measures are critical success factors for reducing waste through procurement process, the four established features are required of all procurement process. Measures through which the procurement process could enhance waste efficiency are further highlighted and discussed in the paper. Findings of this study could assist in understanding a set of measures that should be taken during materials procurement process, thereby corroborating waste management practices at design and construction stages of project delivery process.

“…This suggests ineffectiveness in the way construction waste is currently managed . Notwithstanding the general criticism of existing waste management approaches (Yuan, 2013;Yuan and Shen, 2011), there is an understanding that little success in diverting waste from landfill is credited to legislative and fiscal provisions (Al-Hajj and Hamani, 2011;Pitt et al, 2009). However, there has been calls for increasing stringency of waste management legislations as a means of reducing waste landfilled by the construction industry .…”
