Abstract
The construction industry is often ranked top in producing the largest amount of waste during a project, be it the waste of material resources or the waste of manpower. This has elevated the need for an improved and more structured management technique. This study will look into the principles and practices of lean management pertinent to highway construction projects to analyze whether lean management practices can improve the management efficiency for complex projects. This study adopted a quantitative approach, and a linear regression model has been used to investigate correlations between the lean test factors and the efficiency-dependent variables. It was found that lean management tools that are used repeatedly and the ones that require a high level of detailing are positively associated with efficiency improvement in highway construction projects. In particular, LPS, JIT, and VM were found to be more commonly used in highway construction projects. The research results will aid in the initial decision-making process of the project managers, as they will be able to map different lean tools with their benefits and limitations and then select the one that best suits the project needs and deliverables. Future studies can adopt the interpretivism paradigm to explore new theories and concepts related to highway construction management.
Highlights
When the cost pressure builds, stakeholders often get suspicious about the progress and Return on Investment (ROI) of projects, resulting in further delays, unpaid due, and a growing likelihood of shutting down the entire construction plan
In order to get a better understanding of the need for lean management practices in highway construction projects management, the researcher asked participants about the common challenges they face when dealing with highway construction projects
Lean management has gained getting great popularity in the construction industry, and this study aimed to narrow down the scope to highway construction
Summary
Infrastructure projects have complicated and multi-layered supply chains, which results in many tasks and procedures to be shadowed in the planning and implementation phase [2]. This results in unaccounted delays, budget overrun, and uncoordinated work [2,3,4]. The government cannot terminate the project, and have to keep spending government funds and resources to bring the project to an end [6] It states that a highway project in itself can be considered a complex management project, involving long-distance and distributed logistics plans and strict time deadlines [4]. With a delay of every single day, the overall cost of resources, manpower, and utilities increases dramatically
