Abstract

Pasar Pagi Samarinda, located in Gajah Mada, Samarinda, East Kalimantan, is a staple food market that is planned to be upgraded to a Type A market through a development project outlined in the Detail Engineering Design (DED). According to the DED document prepared by the consultant, the total project value is estimated to be IDR 364,459,686,000. To improve financing efficiency while maintaining construction quality, a Value Engineering (VE) analysis is required. The goal of Value Engineering is to analyze the construction design to achieve the desired function at a lower cost without compromising quality. This study aims to identify design components that can be replaced with more cost-effective alternatives while still being effective. The research method used is descriptive, both qualitative and quantitative, with analysis stages according to Value Engineering standards. The first stage involves gathering information about the initial project design. Next, a functional analysis is carried out to determine the needs of each component. During the creativity stage, alternative, more cost-efficient designs are proposed. The evaluation phase compares the alternatives based on cost and benefits, and finally, the recommendation phase provides the most cost-efficient design solution. The results show that replacing the bored pile foundation design with a pile foundation can significantly reduce construction costs. Using the pile foundation reduces the total project cost to IDR 379,536,168,000, lower than the initial design with a bored pile foundation valued at IDR 371,486,210,000. The cost savings of IDR 8,049,958,000, or about 2.12% of the total project value, indicate that the pile foundation alternative is an effective solution for reducing costs without compromising the construction quality of Pasar Pagi Samarinda

Abstract

Labor productivity is a critical factor in construction project success as it directly affects time, cost, and work quality. In the Palm Vista Residence housing development project, delays in ground floor structural works indicate suboptimal human resource performance. This study aims to analyze labor productivity levels, identify factors influencing productivity, and formulate strategies to improve productivity in sloof beams, columns, and floor slab works. The research employs a quantitative approach with descriptive-analytical methods through field observations, questionnaires, and interviews. Labor productivity is measured using the work sampling method and the Labour Utilization Rate (LUR), while influencing factors are analyzed using multiple linear regression. Strategy prioritization for productivity improvement is determined using the Analytical Hierarchy Process (AHP). The results show that labor productivity is at a moderate level and is significantly influenced by work experience, managerial aspects, and coordination and planning. The priority strategies include improving worker competence and strengthening project management practices. These findings are expected to provide practical guidance for construction labor management to enhance efficiency and ensure timely project completion.

Abstract

Roofing work plays an important role in hospital building construction because it affects costs, time, comfort, and structural performance. In the Muhammadiyah Rodliyah Achid Moga Pemalang Hospital Building Construction Project, the existing Kliplok zincalume roofing system was costly and had low productivity. This study aims to obtain more efficient roof design alternatives through Value Engineering (VE) based on SAVE International standards, including information gathering, FAST function analysis, creative stage, evaluation, and development. Two alternatives were developed: Alternative 1 uses SDS tapping screws with 3.0 mm CNP purlins, and Alternative 2 uses 2.3 mm CNP purlins. Both alternatives fulfill the main function with a value index >1.0. Alternative 1 provides the highest cost savings of 27.96%, increases productivity from 25 to 35 m²/person-day, and reduces the implementation duration by four days. A 10-year Life Cycle Cost analysis shows the lowest cost in Alternative 1. Value Engineering has proven to be effective in improving the cost efficiency and performance of hospital roof work.

Abstract

Time delays and cost overruns remain major problems in building construction projects, particularly in concrete structural works that dominate project duration and cost. This study aims to evaluate the application of re-engineering in concrete structural work methods on the time and cost performance of multi-storey building projects. A quantitative approach using a case study method was employed through comparative analysis between the existing method and alternative methods. The analyzed alternatives include ready-mix concrete with Sika Viscocrete 8007 admixture and semi-system formwork as Alternative I, ready-mix concrete with system formwork as Alternative II, and ready-mix concrete with Sika Viscocrete 8007 admixture combined with system formwork as Alternative III. The results show that all alternatives perform better than the existing method with a duration of 243 days. Alternative I reduced the duration to 208 days with cost efficiency of IDR 55,781,730 or 0.214 percent. Alternative II reduced the duration to 203 days with cost efficiency of IDR 187,553,261 or 0.724 percent. Alternative III achieved the best performance with a duration of 168 days, accelerating 75 days and providing the highest cost efficiency of IDR 243,334,991 or 0.941 percent. The study concludes that re-engineering effectively improves project time and cost performance, with Alternative III as the optimal method.

Abstract

Construction project control requires careful planning to avoid delays and cost overruns. This study aims to evaluate the performance of the CBT Laboratory Building construction project at the Faculty of Medicine, Wahid Hasyim University, Semarang, in terms of cost and time using the Earned Value Analysis (EVA) method, and to analyze acceleration alternatives using the crashing method. The method used is a quantitative approach with a case study, based on project data such as the Budget Plan (RAB), S-curve, and work progress reports. The analysis was carried out using the Earned Value Analysis (EVA) method to assess project performance in terms of cost and time through indicators such as CV, SV, CPI, and SPI. Furthermore, an acceleration analysis was conducted using the crashing method to determine the optimal alternative for overcoming project delays by considering time and cost efficiency. The results of the Earned Value Analysis indicate that the project experienced delays and cost overruns, as shown by SPI < 1 and CPI < 1. The estimated project completion time increased to 227 days, longer than the initial plan of 217 days, while the estimated final cost reached RP 5,451,241,064.85, exceeding the initial budget. Acceleration efforts using the crashing method show that adding adding labor is more efficient than working hours (overtime), resulting in a project duration of 212 days with lower costs of RP 5,658,221,364.08. Thus, the Earned Value Analysis method is effective for evaluating project performance, while crashing can be a solution for acceleration by considering time and cost efficiency.
