The development of more effective management techniques has become essential for the improvement of working conditions within the company. The construction industry is characterized by unpredictable and fluctuating construction processes which increase the level of risk of accidents. In this context, this work aims at conducting a synthesis of the most reliable research in the field of safety management in order to study the contribution of Lean Construction practices in the promotion of safety. The study evaluates the potential effectiveness of Lean Construction tools such as (Last Planner System, Visual Management, 5S, Error-proofing) in promoting the safety on construction sites. This study shows that lean construction tools have a great potential to improve the safety performance. Several Lean Construction practices such as the correlation between scheduled tasks and the ability of the staff working on site, choosing of working methods in compliance with safety requirements, the incorporation of visual tools, and the Simplification of workflow could minimize the risk of accidents and promote the worker safety through minimizing hazards, motivating people involvement in the planning phase and preventing human errors.

The application of lean construction theory in building green substation was discussed. The study on integration of design-build indicated that the electric power design institute as the general contractor should change the mode of only setting up one secondary organization to manage the engineering, and should improve the management system and change the producing idea. The study on the combination of the last planner system and building the substation indicated that the measures of arranging the work and setting the workload reasonably and enhancing the supply of important resources etc. could increase the Percent Plan Complete of building the substation. At last, the 4-saving and 1-environmental protection measures of green construction of substation were brought out.

One of many hazardous workplaces includes the construction sites as they involve several dangerous tasks. Many studies have revealed that material handling equipment is a major cause of accidents at these sites. Though safety measures are being followed and monitored continuously, accident rates are still high as either workers are unaware of hazards or the safety regulations are not being strictly followed. This paper analyses the safety management systems at construction sites through means of questionnaire surveys with employees, specifically referring to safety of material handling equipment. Based on results of the questionnaire surveys, two construction sites were selected for a safety education program targeting worker safety related to material handling equipment. Knowledge levels of the workers were gathered before and after the program and results obtained were subjected to at-test analysis to mark significance level of the conducted safety education program.

Lean construction has been viewed as an effective management approach for reducing the occurrence of no-value or destructive activities, such as wasting resources and safety-related accidents. However, few studies have systematically addressed how and to what extent lean construction practices influence construction safety. To bridge this gap, a conceptual model is developed and validated using a system dynamics approach. The construction system in this model comprises four sub-systems (i.e., environment system, equipment system, management system, and employee system). Data were collected from 448 projects in China. Simulations were conducted to determine the correlations between five types of lean tools and the four construction sub-systems. The results show that: (a) 5S management has significant positive impacts on the control of key locations and facilities at construction sites, and contributes to the mitigation of environmental impacts; (b) visual management can significantly improve safety compliance and safety management; (c) just-in-time management has significantly positive influences on the safety facilities layout and formulation of the safety plan; and (d) the Last Planner® System and conference management are effective in improving safety training and the implementation of the safety plan. These findings provide new insights into the use of lean construction for improving construction safety through the implementation of a targeted lean approach.

Abstract The construction industry is plagued by poor project performance and the adoption of lean construction is seen as a way to address this issue. Therefore, this research aims to assess the implementation of lean construction and its relationships with project performance in the Australian construction industry. Just in time, last planner system, Six Sigma, and 5S management are the four lean construction tools investigated in the research. Data were collected using a questionnaire survey from construction practitioners in Sydney, Australia. Results show that the implementation of these four tools is adequate, although some lean activities need to be implemented at a higher level. Lean construction also has strong correlations with many project performance indicators, demonstrating its value to the construction industry that is in a dire need of improvement. Finally, this research also recommends specific areas for improvements.

Performance measurement has received substantial attention from researchers and the construction industry over the past two decades. This study sought to assess UK practitioners’ awareness of the importance of the use of appropriate performance measures and its role in supporting the application of Lean Construction (LC) concepts. To enable the study to achieve its objectives, a review of a range of measurements developed to evaluate project performance including those devoted to support LC efforts was conducted. Consequently a questionnaire survey was developed and sent to 198 professionals in the UK construction industry as well as a small sample of academics with an interest in LC. Results indicated that although practitioners recognise the importance of the selection of non-financial performance measures, it has not been properly and widely implemented. The study identified the most common techniques used by UK construction organisations for performance measurement, and ranked a number of non-financial key performance indicators as significant. Some professed to have embraced the Last Planner System methodology as a means for performance measurement and organisational learning, while further questioning suggested otherwise. It was also suggested that substance thinking amongst professionals could be a significant hidden barrier that militates against the successful implementation of LC.

Saat ini sektor konstruksi mulai melakukan upaya untuk mengurangi waste sekaligus meningkatkan value dengan mengadopsi teori produksi pada industri manufaktur kepada industri konstruksi yang disebut lean construction (konstruksi ramping). Sistem pengendalian produksi (production control) dengan konsep konstruksi ramping merupakan salah satu sistem dalam perencanaan dan pengendalian jadwal pekerjaan. Komponen yang terdapat konsep konstruksi ramping tersebut adalah sistem the Last Planner (LPS). Last Planner System belum banyak digunakan dan mempunyai potensi yang baik karena merupakan bagian dari komponen lean construction dimana dalam perencanaannya semua pihak dapat terlibat secara langsung dan terkoordinasi sehingga pekerjaan yang direncanakan dapat terkontrol dengan baik dalam pelaksanaannya. Setelah melakukan analisis progress kerja harian, LPS mempunyai indikator kinerja yang digunakan untuk mengukur sejauh mana aliran pekerjaan dapat tercapai dengan baik, adapun kontrol aliran kerja Last Planner System yaitu Master Plan, Phase Planning dan Pull Planning, Lookahead Planning, Constraints Analysis, Shielding Production, Weekly Work Plan dan Percent Plan Complete (PPC) sebagai standar untuk mengontrol unit-unit produksi, menentukan jadwal proyek, strategi pelaksanaan, dan lain-lain. Pada penelitian ini, hasil rata-rata PPC adalah 73%. Tujuan dilakukannya penelitian dengan metode LPS ini yaitu untuk menganalisis implementasi konsep Last Planner System yang dibandingkan dengan progress aktual dalam meningkatkan reliabilitas pekerjaan harian dan Melakukan evaluasi kinerja pekerjaan kontraktor menggunakan LPS. Metodologi yang digunakan pada penelitian ini menggunakan kurva S, data progress rencana dan aktual mingguan proyek juga dilakukan pengolahan data dengan konsep aliran kerja LPS. Untuk membuktikan bahwa perhitungan PPC yang dilakukan sesuai dengan kondisi di lokasi proyek, maka dilakukan perbandingan data dari hasil perhitungan PPC menggunakan LPS dengan progress data mingguan di lokasi proyek yang didapat dari pihak kontraktor. Dari hasil perbandingan data tersebut dapat dilihat bahwa hasil PPC mingguan tidak jauh berbeda dengan hasil data progress mingguan yang didapat dari pihak kontraktor. Hal ini membuktikan bahwa LPS dapat meningkatkan reabilitas perencanaan di atas 70% sehingga tingkat resiko terjadinya keterlambatan proyek akan semakin kecil.
