Special Issue Information

Dear Colleagues,

Construction is perceived as one of the least efficient industries. A great deal of improvements must be made for construction to positively contribute to shaping future sustainable economies and societies using innovative tools, methods and technologies that enhance project management practices. The aim of this Special Issue is to provide a platform for researchers and stakeholders to present their latest research on construction productivity and sustainable construction management practices at the evaluation, organization, planning, monitoring, control and close-out stages. High-quality research articles and reviews are welcome. Papers on, but not limited to, the following topics, are welcome:

  • Lean construction;
  • Project monitoring and control;
  • Offsite construction, prefabrication and modular construction;
  • Life-cycle assessment;
  • Portfolio management and project prioritization;
  • Building information modelling;
  • Digital construction;
  • Industry 4.0 applications in construction;
  • Smart construction and IoT;
  • Connected construction sites;
  • Construction supply chains;
  • Construction safety.

The construction of reinforced concrete (RC) structures inevitably consumes an excessive number of rebars, leading to significant cutting waste and carbon emissions. Extensive research has been conducted to minimize this issue and its consequences; however, these methods consistently consume a substantial number of rebars. This includes a previous study that utilizes the lap splice position optimization and special-length rebar concept without considering the lapping zone regulation. Moreover, conventional lap splices pose inherent drawbacks that could jeopardize the structural integrity of RC members. In contrast, mechanical couplers eliminate the need for rebar lapping, effectively reducing rebar consumption. This research aims to evaluate the impact of an integrated mechanical coupler and special-length-priority minimization algorithm on the reduction in rebar consumption and cutting waste in RC columns, achieving near-zero cutting waste. To validate the effectiveness of the proposed algorithm, it was applied to the column rebars of an RC building. The results revealed a significant reduction in the ordered rebar consumption by 18.25%, accompanied by substantial reductions in the cutting waste (8.93%), carbon emissions (12.99%), and total costs (9.94%) compared with a previous study. The outcomes provide the industry with insights into further reducing rebar consumption and its related consequences. Applying the proposed algorithm to various construction projects will further amplify the corresponding benefits. Full article
