Application

Design takeaway

When implementing lean construction in megaprojects, prioritize practices related to 'People Involvement and Continuous Improvement' and 'Planning and Scheduling' for the greatest positive effect on adoption and project outcomes.

How to apply

For large-scale construction projects, conduct an assessment of current lean practices and focus on enhancing 'People Involvement and Continuous Improvement' and 'Planning and Scheduling' to maximize lean adoption and project success.

Project actions

  • 01When designing a process for a large project, consider how to integrate 'lean' principles.
  • 02Think about how to measure the impact of different process improvements on project efficiency and sustainability.

Method & Evidence

AimTo develop and validate a comprehensive model that links specific lean construction practices to their influence on the overall adoption of lean construction in megaprojects, and to prioritize these practices based on their impact.
MethodMixed-methods research, combining literature review, expert interviews, and quantitative survey data analysis using Structural Equation Modeling (SEM) and Fuzzy Synthetic Evaluation (FSE).
ProcedureResearchers identified 35 lean construction practices through a literature review and expert interviews, categorized them into six constructs, and then surveyed 379 professionals. SEM was used to test the relationships between the practice categories and lean construction adoption, followed by FSE to rank the individual practices by impact.

Strengths & Limitations

Strengths

  • +Comprehensive model development and validation using mixed methods.
  • +Empirical evidence from a large sample size in a relevant context.

Limitations

The complexity of megaprojects means that isolating the exact impact of a single lean practice can be challenging in a smaller design project. Generalizing findings from a specific economic context might require careful consideration.

Reliability & validity

The study employed SEM and FSE, robust statistical techniques, to establish the validity and reliability of the model. The use of a large sample size and mixed methods further strengthens its reliability and generalizability within the studied context.

Think critically

How might the prioritization of lean construction practices differ in projects with different scales, complexities, or cultural contexts compared to the megaprojects studied?

05

Design Principles

"Strategic implementation of prioritized lean construction practices drives efficiency and sustainability in complex projects."

Megaprojects are prone to significant inefficiencies. Understanding which lean construction practices have the most impact allows project managers to strategically implement solutions, leading to reduced waste, improved collaboration, and more sustainable outcomes in complex construction environments.

06

What This Means for Your Design

This research shows that for big construction projects, focusing on teamwork, always trying to get better, making sure things are safe and good quality, and planning well are the most important ways to make 'lean construction' work and make projects more sustainable.

How to use in your project

  • 1.Use the prioritized list of lean construction practices to inform the development of a new process or system for a design project.
  • 2.Reference the validated model to justify the selection of specific design strategies aimed at improving efficiency or sustainability.
