LEAN construction @ JTC project in Singapore


Project Overview

The project involved Piling works for erection of a 4-storey multi-user business park development with cafe and office on Part lot 01759n MK 09 at Cleantech Loop (western water catchment planning area)

Project Highlights

Cost reduced by 9.5%

PPC increased by 56%

Punctuality increased by  63%


"Lean PlanDo was utilized to track and apply lean principles in the construction project by JTC at Cleantech Loop. It offers an effective set of cloud based lean tools for reducing wastes and sharing information to all members of the project team. It is suitable to track and monitor approvals and other constraints to address issues like construction delays and improve productivity "

The Singapore construction industry is projected to grow at 22% annually in 2016 and beyond. In 2015 construction productivity grew marginally at a rate of 0.1% annually, thus reducing the demand.

Construction companies need to be better informed about the low productivity issue and alternative ways of improving their operational efficiency through application of Lean methods and also its other benefits of improving their competency and profitability to thrive in this economic landscape.

Use of Lean methods

Till now Lean has been an unknown or unexplored practice in the construction industry in Singapore but the companies and the Government agencies are now open to explore new alternative methods to improve productivity. It is known across the construction industry that adoption of innovative technology alone will not bring in a big change in the productivity. This needs to be supported with optimization of the processes that utilize these technologies to make the bigger impact and boost productivity. 

In the coming years, applying Lean Methodology will make a big difference to the Singapore construction landscape by offering significant reduction of inherent wastes in the industry and addressing the fragmentation prevalent to sustain a fast growing sector. Use of new process, identification of wastes in the process and optimization will need to be supported by customer friendly technologies like cloud or mobile to leap frog the adoption of lean practices as compared to other American and European counterparts.  


JTC Project Report & Study

The study comprises the application of lean planning and execution methodology called Lean PlanDo in a Piling construction project in Singapore. The main goal of the study was

  • To test-bed Lean PlanDo and measure the Key performance indicators of its benefits
  • To create a positive impact on the project in terms of increasing productivity or speedy completion
  • To evaluate and validate assumptions made with Lean PlanDo in commercial projects and make it commercial ready
  • To understand the reasons that may inhibit the use of lean methods commercially in construction projects

Methodology of Analysis and Study

The data and analysis in the report comes from two modes of study in the project: 

  • Application of Lean Principles using Lean PlanDo in the construction project where the key members were trained on the application and usage. The contractors’ team used the Lean PlanDo to be applied to track and monitor the upcoming work plans and record the progress by updating the current progress. This was both qualitative and quantitative in nature
  • A survey and personal interview was conducted with the key project members regarding the awareness of Lean and benefits of its application post its usage and completion of the project. Results of the survey are also presented. 

Observed Results and improvements


Survey Report

Important findings from the survey were the benefits of Lean and the key reasons why companies have not adopted this at a large scale into construction. 

Some key reasons why companies have not adopted lean in greater masses: 

  • The perception that Lean implementation takes time, and that the implementation cost is expensive
  • there is an overall lack of understanding of lean and its benefits and current lack of industry support in adoption
  • Lack of knowledge and awareness 

The benefits from adopting lean have been clearly identified as 

  • Greater productivity
  • More focus by supervisory staff on managing workers
  • Better risk management

Direct benefits of adopting Lean PlanDo were indicated as 

  • Reduced construction delays 
  • Increased productivity in construction projects
