Abstract

Conventional Bill Of Quantity (BOQ) often faces inaccuracies in estimating structural work volumes due to limited detail and potential human error. This study aims to analyze the accuracy of quantity take off (QTO) using Building Information Modeling (BIM) through Autodesk Revit 2024 in the RSUD Dr. Iskak Tulungagung project. Research data included working drawings (shop drawings) and BOQ, which were modeled in 3D to generate structural work volumes from foundation to roof levels. The analysis revealed notable differences between the conventional method and Revit, with concrete volumes differing by 71.31 m3 or 9.46%, and reinforcement volumes differing by 267.981 kg or 4.51%. These findings confirm that Revit provides more detailed and consistent volume estimations, thereby enhancing project planning reliability while reducing manual calculation error.

Abstract

E-Tendering is an electronic-based procurement method that integrates all parties involved in construction projects through a digital platform, simplifying communication, document exchange, and transactions from the initial stage to project completion. The primary objective of implementing E-Tendering in the construction sector is to improve efficiency and transparency in the procurement process of goods and services. However, construction service providers often face obstacles in E-Tendering, such as limited technological proficiency, administrative errors that may disqualify bids, and technical issues like internet connectivity and platform system reliability. Therefore, this research aims to identify the barriers and level of understanding of E-Tendering among construction service providers in Surabaya. A total of 51 respondents were selected using snowball sampling, based on their participation in the E-Tendering system. Data processing in this study employed a quantitative approach using the Fuzzy AHP method to analyze the criteria and sub-criteria related to understanding and obstacles in participating in electronic construction service tenders (E-Tendering). The results of the analysis of service providers’ understanding of the E-Tendering system using the AHP method showed a λmax value of 9.09, a Consistency Index (CI) of 0.01, and a Consistency Ratio (CR) of 0.007. The CR value, which is far below the threshold of 0.10, indicates that the respondents’ assessments are consistent, meaning that the pairwise comparison results of the nine criteria can be considered valid and reliable.

Abstract

Delays in high-rise building construction projects in Surabaya are a crucial issue as they can significantly affect cost, quality, and project completion schedules. This reserach intends to identify the dominant factors contributing to project delays using the Relative Importance Index (RII) method, considering both frequency and impact aspects. Data were obtained from 80 valid respondents who hold strategic roles in construction project implementation, such as Project Managers, Site Managers, Site Engineers, Estimators, Field Supervisors, General Managers, and Company Directors. The analysis results indicate that in terms of frequency, the dominant factors are unfavorable weather conditions (RII = 0.750), labor shortages (RII = 0.743), and design changes during construction (RII = 0.735). Meanwhile, in terms of impact, the dominant factors are delays in material delivery (RII = 0.780), labor shortages (RII = 0.770), and substandard material quality (RII = 0.740). These findings emphasize that labor shortage consistently influences project delays in both frequency and impact, while weather and material factors show different patterns between occurrence and consequence. All dominant factors were classified into the High-Medium category, indicating that they should be prioritized in project risk management.
