Abstract

This study aims to analyze project cost and time acceleration using the Crashing Method by adding three hours of overtime work and additional labor. Delays in construction projects often lead to budget overruns and inefficiencies, making acceleration techniques essential for ensuring timely project completion. The research evaluates cost efficiency by comparing the total project budget before and after implementing the Crashing Method. Using both qualitative and quantitative approaches, this study examines the impact of different acceleration strategies on cost increase and time reduction. The findings indicate that project completion time can be significantly reduced using both methods; however, overtime results in higher cost increases compared to additional labor. While overtime provides immediate acceleration, it incurs higher expenses due to increased labor wages, whereas adding workforce results in gradual but more cost-effective acceleration. Furthermore, the study underscores the importance of selecting the appropriate acceleration approach based on project constraints, workforce availability, and financial considerations. Effective resource allocation, labor management, and risk assessment are critical factors in minimizing costs while maximizing efficiency. By analyzing the trade-offs between cost and time, this study provides valuable insights into the optimal strategy for project acceleration in construction management. The findings offer practical recommendations for contractors, project managers, and stakeholders to optimize resources and maintain budget control while ensuring project completion within the scheduled timeframe.

Abstract

The implementation of construction projects often faces various risks that can lead to delays, cost overruns, and decreased quality of work. One example occurred in the project to build a dormitory for students of the Riyadlus Sholihin Islamic Boarding School in Probolinggo City, which experienced a time deviation despite acceleration efforts. This shows the importance of implementing systematic risk management to identify and address potential risks from the beginning of project implementation. This study uses a descriptive quantitative approach through the dissemination of questionnaires and interviews to related parties in the project. The analysis was carried out using the Severity Index method to calculate the level of probability and impact of each risk, as well as the probability and impact matrix to determine the level of risk significance. The dominant risk is then further analyzed to determine mitigation actions. The results of the study showed five risks with a "Very High" level, namely the preparation of the wrong work method, poor coordination between parts, the accuracy of completing work within a certain duration, poor planning and scheduling, and low labor productivity. Mitigation strategies are developed to reduce the impact of these risks, including through training, improved communication, the use of planning software, and strengthening the monitoring system. This research makes a real contribution to the risk management of construction projects in a more effective and structured manner.

Abstract

Bridge infrastructure plays an important role in supporting connectivity and regional economic growth. However, in their implementation, bridge construction projects often face delays due to technical factors such as weather, soil conditions, as well as managerial and coordination constraints. One of them occurred in the Purworejo Bridge construction project in Mojokerto Regency which experienced a delay in progress of -14.88% in the 12th week of implementation. This delay requires accelerated efforts so that the project is not included in the critical contract category. This study seeks to examine the approach of accelerating implementation time through the Crashing method through increasing working hours (overtime) and calculating costs efficiently to mitigate delays. The methodology used includes the formulation of a network using Microsoft Project, the identification of critical paths through the Critical Path Method (CPM), and the calculation of acceleration costs based on Cost Slopes. The results of the analysis show that the acceleration of work can be achieved both technically and economically. This method allows the project to reduce delays, thus removing them from the classification of vital contracts. The study significantly improved the decision-making process for the timely and cost-effective implementation of development projects.

Abstract

Indonesia is in an active seismic area prone to earthquakes, including the city of Surabaya, which is crossed by the Kendeng Fault. Many modest homes in the area were built without considering earthquake resistance standards, thus posing a high risk of damage and casualties. This research aims to evaluate the reliability level of simple house buildings against earthquakes in the Tandes, Asemrowo, and Sukomanunggal Districts, West Surabaya, which are crossed by the Kendeng Fault. The methods used are Rapid Visual Screening (RVS) based on FEMA P-154 guidelines and Fault Tree Analysis (FTA) as a deductive approach to map the causes of structural vulnerability. The results showed that none of the 30 housing units met the safety criteria; 76.7% of buildings require follow-up evaluation, and 23.3% are classified as unsafe. The dominant factors affecting vulnerability include non-standard foundation conditions, the absence of structural fastening elements, the use of wall materials without reinforcement, and the irregularity of building geometry. These findings indicate the need for technical intervention through structural retrofit, public education about earthquake-resistant buildings, and the formulation of regulations for the construction of residential houses in earthquake-prone zones. The combination of RVS and FTA methods has proven effective in providing a comprehensive overview of the structural condition of existing buildings and can be used as the basis for seismic risk mitigation strategies in urban areas.

Abstract

The need for housing continues to increase as the number of inhabitants increases. Housing development as one of the efforts to meet the needs of the community for residential houses. The Andalusian Griya Giri housing estate in Gresik Regency was built with a type. However, with the vast area in Gresik Regency and the fierce competition of housing developers who offer housing in a higher segment and at prices that do not differ much, it can be concluded that this housing is a waste of costs in development. Therefore, a way is needed to overcome this problem, namely by applying Value Engineering. This study aims to analyze the optimization of the calculation of the cost budget plan without reducing the quality and function of the building with the Value Engineering method. The analysis technique in Value Engineering of this study uses a comparative method with cost analysis. This method compares the profit price of the landcape design before it is redesigned with the design that has been redesigned, namely changing the house plan, appearance and number of house compositions / site plans so that maximum profit is obtained. This analysis uses the stages of the Value Engineering plan, namely the information stage, stage, creative, analysis stage, recommendation stage and presentation stage. Based on the results of the Value Engineering analysis at the Griya Giri Andalusian Housing Project in Gresik district, the most profitable design alternative was to use Design C with the change of type 38/72 housing units to 36 units. The profit price after redesigning from the original design, the production price of the type 38 house is Rp. 122.2 40. 00,000 becomes Rp. 9 0.728.514. The amount of profit increased generated after the redesign of the original design and the change in the number of house compositions / site plans was carried out amounting to Rp 7,864.960. 000 becomes Rp. 9,981,773,496.
