Abstract

Construction project delays are a critical issue frequently encountered during project implementation. These delays may result from various internal factors such as labor shortages, late material deliveries, and incomplete design plans, all of which directly impact the project completion schedule. The Fault Tree Analysis (FTA) method needs to be applied to the Amaris Extension Gorontalo project to identify and mitigate delay-causing factors that pose a risk to timely project completion. The FTA method is used to identify the root causes of project delays by analyzing the basic failure factors. Data were collected through observations, interviews, and project schedules. The analysis was conducted by constructing a fault tree. This study was carried out on the Amaris Extension Gorontalo project with a duration of 365 days. The results of the study indicate that delays were primarily caused by incomplete design planning, labor shortages, and issues related to materials and execution. The Fault Tree Analysis (FTA) method successfully identified the root causes and the top events with the highest probability of occurrence in weeks 19 and 20. These findings provide a solid foundation for improving future project management.

Abstract

Delays in project execution can be addressed through project control techniques such as the crash method, which aims to accelerate project duration without significantly increasing costs. This study investigates the application of the crash method in the acceleration of a Type B Terminal construction project (Phase 1) to evaluate its impact on project duration and cost. The research employs a quantitative descriptive approach, combining literature review and field observation. Data collection includes the original project schedule and cost information, followed by critical path analysis using the Critical Path Method (CPM). Based on the identified critical activities, the study applies crash analysis by reducing the duration of critical tasks and adding overtime hours, then compares various scenarios to determine the most cost-effective acceleration strategy. The results reveal that an additional 4 hours of overtime is the most efficient option, reducing the project duration by 43% while incurring the lowest total cost of Rp 3,860,600,576.59. This finding highlights that proper application of the crash method can lead to substantial time savings with manageable cost implications. In conclusion, the crash method proves to be an effective strategy for project time optimization when supported by accurate scheduling, cost analysis, and critical activity identification. The study recommends further research to validate these findings across different types of infrastructure projects using updated specifications.

Abstract

In construction projects, there are four main aspects that must be considered: cost, time, quality, and occupational safety. One of the biggest challenges is the cost aspect, which often faces issues such as budget overruns, overtime work, and quality degradation. These issues can be categorized as unnecessary costs. One approach that can be used to reduce unnecessary costs is the application of the Value Engineering concept. The implementation of Value Engineering is carried out through field surveys, participatory observations, and secondary data analysis from project documents such as the Budget Plan (RAB), Detailed Engineering Design (DED), and Unit Price Analysis (AHSP). The analysis is conducted through several stages, including the Cost Model, Cost Breakdown, Pareto rule analysis, function analysis, creative stage, Value Engineering analysis, Life Cycle Cost analysis, and recommendation stage. The results show that the application of Value Engineering in architectural works can provide significant cost efficiency. The total savings reached IDR 69,552,162.86, or 10%. Specifically, for wall works, the applied alternative resulted in savings of 7.53% or IDR 62,784,374.25. For door and window frame works, the selected alternative generated savings of 1.09% or IDR 4,503,000.00. Meanwhile, for flooring works, the applied alternative was able to save 1.4% or IDR 2,264,788.61.

Abstract

The construction sector is among the industries with the highest rate of workplace accidents, making the implementation of an effective Occupational Safety and Health (OSH) system crucial. This study analyzes the application of OSH practices in the construction project of the Hasri Ainun Habibie Regional Public Hospital’s inpatient building in Gorontalo. Employing a quantitative descriptive approach, data were collected from 15 respondents, including safety experts, contractors, consultants, and workers, using questionnaires and interviews. The data were analyzed using the Relative Importance Index (RII) to assess the level of OSH implementation based on policy, training, use of personal protective equipment (PPE), emergency response procedures, and accident risk management. The findings indicate that the overall implementation of OSH in this project is categorized as “highly applied,” with the highest RII score of 0.93 for worker health insurance coverage and 0.95 for accident handling readiness, reflecting effective emergency preparedness. However, some areas, such as routine health checks and waste management, require further improvement. The study provides practical recommendations for strengthening OSH practices in healthcare facility construction projects, which involve higher safety risks and operational complexity than general construction projects. These findings are expected to serve as references for contractors, consultants, and policymakers in developing adaptive safety strategies aligned with regulatory standards.

Abstract

The tender process in construction project procurement is pivotal for determining the success of infrastructure development A vital part of this process is the method of determining the bid price used by contractors to secure a probability of winning while also achieving optimum profit. This study aimed to analyze and compare the mark-up value, win probability, and expected profit using two bidding strategy models the Friedman Model and the Gates Model in the construction project bidding process at the North Bolaang Mongondow Regency LPSE for the 2022-2023 period. The method used was a statistical approach involving the processing of secondary data from completed project bid data. The analysis was conducted on mark-up data. and the probability of winning and expected profit were calculated for each model The analysis results revealed that each model had distinct characteristics in determining the best bidding strategy The Friedman Model tends to produce more cautious mark-up values with a stable win probability, while the Gates Model offers a bolder approach in its expected profit calculation. Thus, this study has been able to notify construction practitioners in formulating policies on the importance of selecting a bidding strategy method that aligns with market conditions and the number of competitors, thereby enhancing effectiveness in the construction project tender process.

This study aims to analyze the effect of additional working hours (overtime) and additional workforce on project success in the construction of the BPK RI Apartment Building in Gorontalo City. The independent variables examined in this study are additional working hours (X1) and additional workforce (X2), while the dependent variable is project success (Y). Data analysis was conducted using multiple linear regression to examine the relationship and influence among variables. The sample consisted of 41 respondents who were workers and project executors involved in the construction of the BPK RI Apartment Building in Gorontalo City. Data were collected through questionnaires that had been tested for validity and reliability. The results of these tests indicated that all research instruments were valid and reliable, and therefore suitable for use in this study. The results of the analysis indicate that additional working hours and additional workforce simultaneously have a significant effect on project success. This is supported by the F-test results, which show a significance value of 0.037, which is less than 0.05. Partially, the t-test results demonstrate that additional working hours (X1) have a significant effect on project success, with a significance value of 0.023 (< 0.05). Similarly, additional workforce (X2) also has a significant effect on project success, with a significance value of 0.037 (< 0.05). The coefficient of determination (R²) value of 0.399 indicates that the independent variables collectively explain 39.9% of the variation in project success. The remaining 60.1% is influenced by other factors not examined in this study.
