Review On Lean Principles For Rapid Construction

Abstract

Penggunaan prinsip “lean” di dalam proses pembinaan adalah untuk melancarkan perjalanan proses pembinaan terutamanya di tapak binaan dengan mengurangkan aktiviti–aktiviti yang tidak penting untuk melengkapkan kitaran pembinaan secara efektif. Tujuan prinsip ini diadaptasi di dalam pembinaan yang pantas adalah untuk menyelesaikan masalah yang kompleks disebabkan oleh susunan aktiviti yang padat di dalam proses pembinaan itu sendiri. Lima prinsip utama “lean” telah disesuaikan dengan kajian kes. Di dalam aplikasi pembinaan, penggunaan konsep pembinaan pantas adalah sesuai untuk mengurangkan masa aktiviti–aktiviti pembinaan dan memenuhi kehendak tempoh pembinaan. Kelebihan daripada penggunaan prinsip “lean” di dalam pembinaan pantas adalah ianya dapat mengurangkan keseluruhan masa pembinaan, memenuhi kehendak masa pembinaan, lebih berinovasi dan mengurangkan masalah kepadatan aktiviti pembinaan. Kajian ini juga mendapati lapan faktor kejayaan dalam mengaplikasi prinsip “lean” di dalam pembinaan pantas iaitu perancangan yang tepat, memahami keseluruhan kitaran pembinaan dari aspek faktor bukan harga, penggunaan kepakaran, kerja berpasukan yang baik, memahami setiap proses, pengukuran kemajuan, latihan dan penanda aras. Kata kunci: prinsip “lean” pembinaan pantas; kesesuaian; proses pembinaan; pengurangan The general approach within lean construction is to make the construction process as it is normally undertaken on the construction site and leaner by reducing non–value generating activities. The reason on why the lean principles are used into rapid construction is to solve the chronicle and congested activities within the time frame of the rapid construction projects. Five principles of lean were made into comparison in the review of three case studies. In many applications of construction concept, the use of rapid construction method components significantly decreased the construction time required for the project. The most significant benefit has been seen in areas where systems have been using it repeatedly. The benefits from lean principles into rapid construction are the shorten of order fulfillment leading times, less project downtime, more innovation and true reduce the chronicle predecessor. This research has also identified eight critical factors of integrating lean with rapid construction that are proven successful which are planning it right, understanding the whole life construction cycle in non price factor view, utilize knowledge and expertise, integrate the team by working with the end to end supply chain in an integrated manner, understand the end to end process, measure performance to include reporting in your own performance, training and benchmarking. Key words: lean principles; rapid construction; significant; process flow; eliminate waste

Barriers to adopting lean construction in the construction industry: a literature review

“…The SLR is a method that was originally developed in medical sciences and was used in other fields including management. In this method, a comprehensive review on a specific topic and clear research question is done based on an explicit pre-determined method that Koskela et al (2002) "Lean is a way to way to design production systems to minimize waste of materials, time, and effort in order to generate the maximum possible amount of value" Diekmann et al (2004, p. 3) "A continuous process of eliminating waste, meeting or exceeding all customer requirements, focusing on the entire value stream and pursuing perfection in the execution of a constructed project" Yahya and Mohamad (2011) "Lean construction is about managing and improving the construction process to profitability deliver what the customer needs by eliminating waste in the construction flow due to construction contract, specification and agreement between client and other parties by using the right principle, resources, and measure to deliver things right first time" Marhani et al (2012) "Lean Construction is a concurrent and continuous improvement to the construction project by reducing waste of resources and at the same time able to increase productivity and secure a better health and safety environment in order to fulfill the client's requirements as well as contributing toward sustainable and greener environment" Abdelhamid ( 2013)…”

Scientometric Review of Construction Project Schedule Studies: Trends, Gaps and Potential Research Areas

“…However, current available scheduling methods could not achieve collaboration of stakeholders due to the nature of multiparty involvement agreement. Yahya and Mohamad (2011) identified lean principles to reduce nonvalue adding activities through team collaboration's planning effort. Similarly, Kovvuri et al (2016) also found that last planner benefits construction time reduction, quality, cost improvement, build trust, and increase coordination.…”

“…Last Planner System (LPS)) has been widely studied to improve performance of project scheduling. For example, (Yahya & Mohamad, 2011) studied how to apply lean for rapid work flow. The technique is applied to solve CPS constraints via team collaboration (Alsehaimi et al, 2014;Daniel et al, 2017;Kovvuri et al, 2016); -CPS planning and management: CPS planning and controlling of CPS has been examined.…”

“…This management approach has been introduced by Koskela [8], which is emphasised on eliminating construction wastes. Yahya and Mohamad [9] added LC is likely on managing and improving the construction processes. LC also capable of fulfilling the client's needs as well as contributing towards a sustainable and greener environment [10].…”
