"The construction industry has a vast impact on the environment and the economy. Construction project performance requires a focus on increasing the resource efficiency and reducing the impact on the environment during the construction lifecycle. This on-going research is addressed towards the need of improving construction project performance by creating added-value for building projects using quality management (QM) and value management (VM) approaches. This research employs a quantitative approach through a questionnaire survey distributed to construction industry stakeholders. The questionnaire consists of three parts of discussion including identification of critical success factors and barriers that exist typically at each construction stage in building projects, plus identification of additional functions in building projects, and total investment cost for building projects. As the significant findings indicate, this research evaluates how the understanding of quality and its perceived processes plus how the identification of additional functions can be applied to deliver efficiency and more added-value in building construction projects e.g. Energy Efficient Buildings."

Written by two experts in the field, it offers a practical, proven means of quantifying and minimizing risk, to inform business decisions in the design and construction field. Case studies and examples on the proper application of software and principles help make this book an important reference to the field"-- Provided by publisher."The book presents an integrated approach to cost and schedule for qualitative risk analysis. This approach recognizes the value of considering the project schedule when cost is estimated. The approach was created and developed at the Washington State Department of Transportation (WSDOT). The authors have expanded the scope of the process to cover any type of construction, and have provided two case studies developed throughout the book presenting the process in use on an instutional construction project and a heavy civil construction job"

"Classifying accident information into a specific categories provides inspectors with data needed for accident analysis and subsequent decision-making. This research proposes development of a database for accident analysis prevention. It will also presents a template and accident database focusing on fatal electrocutions and falls in the construction industry. Data has been stored in MySQL database, and a program editor has been employed to customize the program for accident analysis. An accident analysis form connected to the database has been developed, along with an accident report in qualitative format and meaningful categories to provide analyzable data. The program can be used as soon as an inspector finishes preparing an accident report; accessing the database minimizes the lead time for translating qualitative reports into analyzable data, so that the Council for Labor Affairs, corporate personel, and inspectors can have real time information about accident trends and patterns for the prevention of repetitive accidents."

"The development of the construction industry in Indonesia has been substantially contributing to the enhancement of the social and economic development of the people. However, its expansion has also become an issue, as the development might be implicated in the abuse of environmental sustainability when the practices of conducting the construction project abandon the rules and regulations of sustainable green construction concepts. Therefore, this study attempted to introduce a quantitative assessment tool called the Green Construction Site Index (GCSI) to evaluate the performance of an ongoing project to meet the sustainable green construction concept. The aim of this study was to investigate the effectiveness of GCSI as a quantitative assessment tool to measure the implementation of the green construction concept conducted by ongoing projects. Data were collected by onsite direct observation, interviews with key personnel, and project documentation review. Data were organized and analyzed using descriptive elaboration. The results showed that three aspects, the Efficiency Index (IE), Productivity Index (IP), and Awareness Index (IA), were effective in assessing 10 ongoing construction projects, categorized as Non-Commercial Non-Residential Building, Commercial Residential Building, and Commercial Non-Residential Building. The index generated using GCSI, upon assessing 10 buildings, was 3.39 and fell into the Good category with IE = 3.51, IP = of 2.86, and IA = 3.84. Another finding shows that the Project Organizational Commitment Index (POCI) to the indicator of the GCSI was 3.31 (Good category) with IPOL = 3.36, IPRO = 3.49, and IPRAC = 2.75. The capability of the GCSI to identify three aspects within a construction project simultaneously and comprehensively suggests the importance of its function as an effective tool that gives benefits to not only the contactors, but also to the authorities that control the green construction–related performance. Therefore, the GCSI is expected to be applied as a standardized reference by both the construction industries and regulating authorities. Despite its satisfactory findings, the GCSI needs to be furthered to achieve its reliability and validity to be adopted internationally."

"Pembengkakan biaya yang terjadi pada proyek konstruksi di Indonesia masih masif dan terus terjadi. Dampak dari pembengkakan biaya diantaranya yaitu penundaan dalam penyelesaian proyek, penurunan kualitas proyek, hingga menurunkan keuntungan stakeholder proyek (Susanti & Nurdiana, 2020). Pembengkakan biaya dapat terjadi akibat adanya pemborosan waste dari kegiatan proyek yang tidak menambah nilai (Non-Value Added). Oleh karena itu, diperlukan pendekatan lean construction untuk meminimalkan pemborosan dan memaksimalkan nilai tambah proyek. Kerangka lean thinking dan metode Value Stream Mapping akan digunakan dalam penelitian ini. Value Stream Mappingmerupakan alat untuk membuat representasi diagram alur dari seluruh langkah dalam suatu proses pekerjaan proyek dengan tujuan untuk menampilkan potensi perbaikan yang dapat diterapkan. Dengan metode ini akan diidentifikasi faktor pemborosan dalam fase perancangan dan fase konstruksi serta rekomendasi untuk mengeliminasi pemborosan pada proyek bangunan gedung bertingkat. Metode yang digunakan dalam penelitian ini adalah validasi pakar, survei kuesioner, dan pengolahan data menggunakan analisa deskriptif, analisa RII, dan analisis uji SPSS 29. Analisis ini akan memberikan wawasan mendalam tentang bagaimana setiap faktor pemborosan berkontribusi terhadap inefisiensi keseluruhan dan biaya tambahan dalam proyek konstruksi. Sebagai hasil dari penelitian, VSM mempengaruhi proyek dalam membantu mengurangi ketidakefisienan dalam biaya operasional proyek & pembengkakan biaya proyek. Hasil penelitian ini diharapkan dapat memberikan rekomendasi praktis yang dapat diimplementasikan oleh para stakeholder proyek untuk meningkatkan produktivitas dan mengurangi potensi dalam pembengkakan biaya proyek.

Cost overruns in construction projects in Indonesia remain massive and ongoing. The impacts of these cost overruns include delays in project completion, decreased project quality, and reduced profits for project stakeholders (Susanti & Nurdiana, 2020). Cost overruns can occur due to wasteful activities in project operations that do not add value (Non-Value Added). Therefore, a lean construction approach is required to minimize waste and maximize the added value of the project. The lean thinking framework and the Value Stream Mapping method will be used in this research. Value Stream Mapping is a tool for creating a diagrammatic representation of all steps in a project work process, with the aim of showcasing potential improvements that can be applied. This method will identify faktors of waste in the design and construction phases and provide recommendations for eliminating waste in high-rise building projects. The methods used in this research are expert validation, questionnaire survey, and data processing using descriptive analysis and spearman correlation using Statistical Product for Service Solution (SPSS). As a result of the research, VSM affects the project by helping to reduce inefficiencies in project operational costs and project cost overruns. The results of this research are expected to provide practical recommendations that can be implemented by project stakeholders to enhance productivity and reduce the potential for cost overruns in construction projects."
