Abstract

Acceleration on projects is frequently used when there is a mismatch between the actual and planned schedules. In addition, acceleration is frequently implemented in response to requests from the project owner to complete the project as quickly as possible to meet specific goals so that the building can be used immediately. The owner of the Dekranasda Building and Hall in West Kalimantan requested that the project be finished immediately so that the Dekranasda Building could be used as the location for a national UMKM exhibition event. The initial plan for this project was scheduled for 152 working days. Because there would be an exhibition event, the project was accelerated to 128 working days. The purpose of this research is to accelerate the project for 24 days. The stages of this acceleration analysis start from finding what activities can be softened, then compiling a network diagram to identify activities on the critical path, followed by crashing analysis to get crash duration, crash cost, and cost slope, then Time Cost Trade-Off analysis is carried out. This research uses the PDM (Precedence Diagram Method) method applied to Microsoft Project to compile a Network Diagram. The results of the acceleration analysis show that the crashing process is carried out until the 12th crashing to meet the target acceleration duration of 128 working days from the normal duration of 152 working days, and the usual 24-day length is shortened. Twelve tasks have been added, raising the overall project cost from Rp. 6,794,007,874 to Rp. 7,091,725,614 by a total of Rp. 297,717,741.

Abstract

Road infrastructure improvement is one of the important elements in supporting a country's economic development. Accurate cost estimation is key to road construction projects' success, ensuring efficient budgeting and resource allocation. This research uses data from interviews, observations, planning documents, and supporting literature sourced from official government websites. The method used is the Work Unit Price Analysis (AHSP) based on the Minister of PUPR Regulation No. 1 of 2022 to estimate the Cost Budget Plan (RAB) for the improvement project of Jalan Parit Demang. The results obtained show that the total project cost reached IDR 15,754,053,157. Meanwhile, the AHSP method provides a reliable framework for cost estimation; the analysis also emphasizes the importance of regular price data updates and contingency planning to anticipate market volatility. The research findings will improve budget estimation accuracy and resource efficiency in future infrastructure projects.

Abstract

Rebar is one of the main materials in a building. The material has been widely innovated by product providers. In addition to using conventional reinforcement on the floor slab, it is now possible to replace the reinforcement with wire mesh reinforcement. Because material costs are a very large cost in construction projects, it is necessary to do proper material planning. This final project will compare the two reinforcements with the aim that project implementers can plan materials appropriately so that it is expected to minimize the huge cost expenditure. In this final project, the reinforcement in the floor slab work will be reviewed in terms of direct waste reinforcement which will be assisted by software cutting optimization pro and reinforcement costs using the AHSP stipulated by Permen PUPR No.1 of 2022. After various stages are carried out, a comparison of the direct waste level, direct waste cost, and cost of the two reinforcements will be obtained. A Comparison of the three reviews found that wire mesh reinforcement is more efficient than using conventional reinforcement.
