Abstract

The permit process must comply with laws and regulations. The permit functions as controlling and supervising tool from the government of activities in certain cases based on the guidelines that must be implemented. The permit also functions as a disciplinarian and regulator in accordance with the law in the administration of government. In the process, several constrains or obstacles often occur in terms of the period of the process as well as technical and non-technical constrains. In this research, an analysis of the scheduling of the site plan permit approval process is based on field data related to the site plan permit approval process with the PERT method. The data used are primary data in the form of interviews and filling in the form of questions and secondary data in the form of a site plan approval process flow. The data that has been collected is then processed and analyzed in several stages. First, calculate the expected time period (te) using interview data and the results of filling in the expected time period (te), so that the expected time period for each activity will be found in accordance with the site plan approval process flow. Second, determine the dependency relationship between activities. In this stage, the relationship between each activity is determined. Third, create a network by changing the existing site authorization process flow into a form of network planning. The results of the schedule using the PERT method are a period of 38 days with alternatives that can be done to reach the time (Tx) of 18 working days in accordance with the Regent Regulations. In addition, the probability of the overall activity being completed is 0.8531 or 85.31%.

Abstract

All construction project require of cost and time control. Controlling of time the most important in the construction implementation so that the project can be in accordance with the time schedule. Controlling of time can be done byconsidering the project implementation performance. Project implementation can be late, faster, or even on time in accordance with time schedule. One of the time controlling that are used in this research is earned value method to know the project performance in terms of time. Object of this research is Building Construction Project of Fave Kotabaru Hotel, Yogyakarta. The data in this research are time schedule, RAB, and weekly progress report to get the value of BCWP and BCWS. Controlling analysis by earned value method obtained the value of Schedule Variance (SV), Schedule Performance Index (SPI), predict the value of estimation to completeand estimation at comlpete (ETC and EAC). Analysis result base on time of Building Construction Project of Fave Kotabaru Hotel was predicted to become late. All value of Schedule Variance (SV) from week 25 until 28 is negative (-) and the average value of Schedule Performance Index (SPI) at 7th month from week 25-28 is 0,63 (<1). The results mean that the time performance of the construction project is slower than the time schedule. Based on the performance at the 7th month observation, obtainedthe value of estimation to complete (ETC) the project is 20 weeks, then estimation at completion (EAC) is 48 weeks, 8 weeks slower than time schedule. The final result shows that the project was too late, so that it need to be re-schedule.

Abstract

Quantity take-off menjadi hal yang sangat krusial karena menjadi dasar perhitungan yang berkelanjutan untuk tahap perencanaan. Quantity take-off digunakan untuk perhitungan BoQ atau estimasi biaya. Kesalahan dalam memperkirakan quantity take-off akan menyebabkan penyimpangan biaya dan atau adanya penyimpangan pada volume kebutuhan material. Diperlukan adanya perhitungan quantity take-off dan rencana anggaran biaya (RAB) yang efektif yang dapat dilakukan dengan metode BIM 5D. Penerapan konsep BIM memudahkan dalam ekstraksi quantity take-off langsung dari model 3D hingga kemudian terintegrasi dalam pengolahan estimasi biaya. Penelitian ini bertujuan untuk mendapatkan estimasi biaya dengan menerapkan konsep BIM 5D. Menggunakan bantuan software PriMus untuk membuat AHSP dan PriMus IFC untuk ekstraksi quantity take-off. Hasil yang didapatkan dari penelitian ini, bahwa dengan menggunakan konsep BIM 5D estimasi biaya yang dihasilkan terdapat selisih sebesar 7% lebih kecil dari anggaran biaya rencana awal. Hal tersebut terjadi dikarenakan perbedaan detail perhitungan volume pada perencanaan awal secara konvensional yang dihasilkan, serta beberapa diantaranya disebabkan karena data dari perencanaan modeling tidak memodelkan semua elemen konstruksi, yang kemudian muncul tanggung jawab berkelanjutan atas masalah tersebut oleh BIM modeler. Implementasi konsep BIM 5D dapat meningkatkan komunikasi, kolaborasi, dan menciptakan komitmen atau tanggung jawab yang berkelanjutan sehingga proses pengambilan keputusan menjadi lebih cepat dan tepat.

Abstract

The implementation of Building Information Modeling (BIM) has generally been proven to provide changes in the way construction projects are managed and bring long-term benefits in terms of efficiency, cost, and quality. The Common Data Environment (CDE) platform is instrumental in fostering collaboration and coordination in the implementation of BIM. The objective of this study is to examine the barriers to the integration of the CDE in BIM-based construction management during the execution phase of construction projects. To achieve this goal, a survey questionnaire was created to collect feedback on engagement, the main barriers that have been identified through comprehensive literature insights. Primary data was collected from the questionnaire on this project case study with a total of 14 respondents who were directly involved in the project and had access to CDE. The final results show that the main barriers involved are the habits of the conventional system that exists in the company (the company's organizational culture). In order to effect a transformation toward sustainable buildings within the context of a digital construction culture, it is imperative that there be an increased emphasis on encouraging the adoption of this new paradigm. The results of this study will prove to be of the utmost importance for professionals in the construction industry, particularly those in Indonesia, who are in the process of adopting BIM.

Abstract

The concept of 'quality' is becoming increasingly recognized across industrial sectors, as evidenced by the emergence of methodologies such as TQM, Kaizen, and Quality Circles. The 5R (Reduced, Refined, Radiant, Retain, Reliable) program, which includes Sort, Set in Order, Shine, Standardize, and Sustain, has become an essential component in enhancing efficiency and quality management within a company. This study aims to evaluate the effectiveness of the 5R program implementation on the achievement of Total Quality Management (TQM). The method of this study is a descriptive approach using a case study design and mixed methods, integrating both qualitative (field observations and interviews) and quantitative data (audit scores and monthly performance metrics). This combination enables a comprehensive evaluation of the 5R program. Data were collected through field observations, in-depth interviews, analysis of audit results, and monthly performance scores from ten work areas. Manufacturing company PT ADP, as a case study, was employed to examine the benefits of the 5R implementation in relation to TQM standards. The findings contribute to practical knowledge by demonstrating that structured implementation of 5R can significantly support Total Quality Management (TQM) in manufacturing settings, particularly in enhancing productivity, discipline, and operational efficiency. The results indicate that the 5R program can support the foundation of TQM by ensuring higher work efficiency, reduced waste, and a more disciplined and responsible work ethic. The 5R culture is essential in supporting the implementation of TQM to improve quality and innovation for sustainable growth, competitiveness, adaptability, and customer satisfaction

Abstract

The implementation of Building Information Modelling (BIM) in Indonesia’s construction industry has grown steadily, but it mainly focuses on the planning stage. One important function of BIM, automated quantity take-off (QTO), has great potential benefits for contractors during the construction phase. However, its use often faces challenges due to poor model quality. This study explores the implementation of BIM-based automated QTO in a bridge construction project to support digital construction practices from a contractor’s viewpoint. A structured modeling approach that follows Level of Development (LOD) 350 was used to improve model quality, ensure data consistency, and allow reliable quantity extraction and shop drawing generation within the BIM environment. The QTO results for the concrete and reinforcement materials in this analysis showed a total concrete volume of 2,075.30 m³, and the reinforcement volume was 381,548.21 kg. The findings also highlight the need to align modeling practices with the requirements of the construction phase to fully take advantage of BIM. Overall, BIM-based automated QTO can enhance construction performance, reduce material waste, and improve contractor decision-making, providing evidence to support broader industry adoption and informing future guidelines and policy initiatives for digital construction in Indonesia.
