Lean Construction Methods Reduce Waste by 30% and Boost Project Efficiency

Implementing lean construction (LC) methods significantly reduces waste, a major barrier to productivity, and enhances overall project performance and sustainability.

African Journal Of Applied Research · 2025

Key Findings

01Efficient utilization of lean construction significantly reduces waste.
02Integrating Building Information Modelling (BIM) with soft lean tools improves quality and productivity.
03Holistic LC approaches combining soft and hard tools lead to efficient and sustainable project outcomes.

Application

Design takeaway

How to apply

Begin by identifying and quantifying key waste streams in current construction processes. Then, pilot lean tools such as '5S' or 'Last Planner System' in a specific project phase, integrating BIM where possible to track progress and resource utilization.

Project actions

01Clearly define what constitutes 'waste' in your specific design project context.
02Consider how digital tools can support the implementation of lean principles.

Method & Evidence

AimTo investigate the implementation and effectiveness of lean construction methods in enhancing project performance and sustainability within the construction industry.

MethodExploratory case study

ProcedureA case study was conducted in Ghana, involving purposive sampling of ten professionals (architects, project managers, engineers, quantity surveyors) actively involved with lean practices. Data was analyzed using NVivo 11 software for thematic analysis to understand how lean construction contributes to efficient and sustainable project performance.
