The subgrade plays an important role in supporting and spreading the load from the pavement to the underlying soil. Terzaghi, et al. (1967) state that soft soils can pose serious challenges in geotechnical engineering, due to their tendency to experience large settlement under structural loads. Handling soft soils often requires specialized methods such as preloading, vacuum consolidation, or the use of geosynthetics to improve stability. One of the geosynthetics used in handling soft soil is Expanded Polystyrene (EPS) Geofoam. This research aims to determine the settlement behavior of soil embankment on soft soil reinforced with EPS geofoam. The settlement behavior was obtained with the help of GeoStudio software. EPS geofoam has been used since 1960, this material weighs about 1% of the soil weight and less than 10% of the weight of other embankment materials. As a lightweight embankment material, EPS geofoam can reduce the load imposed on the embankment structure. Modeling of soil embankment on soft soil using various types of EPS geofoam material in this research uses GeoStudio software. The modeling analysis uses SIGMA/W in GeoStudio. Numerical modeling of variations in the type of EPS geofoam material in the embankment on soft soil gives the results of a decrease that is not too significant. The settlement results from modeling with GeoStudio are 0.33240 m for EPS 22, 0.33264 m for EPS 29, 0.33323 mm for EPS 39. EPS 39 provides 0.25% higher settlement than EPS 22.","PeriodicalId":519042,"journal":{"name":"Sustainable Civil Building Management and Engineering Journal","volume":" 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141676388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research explains the Building Information Modeling (BIM) application which uses Autodesk Revit software to calculate Quantity Take Off volume. The aim is to find out the difference between volume calculations using conventional methods and volume calculations using the BIM method and Quantity Take Off volumes in architectural work and structural work. A comparative analysis of conventional methods and the use of Autodesk Revit provide an overview of the efficiency and effectiveness of implementing BIM software in the Bantul Satpol PP Building Construction Project with a focus on structural an architectural work investigation studies.

This research method includes preparatory steps, data collection techniques, 3D modeling, and data analysis based on volume the use of BIM software and conventional methods.

Magetan Regency has several areas drained by various rivers that have the potential to cause flooding problems in the event of high rainfall. Hydrological analysis is needed to determine the various rivers that are potentially unable to accommodate water capacity due to high rainfall, causing flooding problems. Thus, research aims to assess flood mitigation control based on a 25-year return period flood discharge (Q25) using the HSS Snyder method and HEC-HMS software. The flood inundation area due to river runoff is analysed using HEC-RAS 6.4.1 software using a 25-year return period discharge (Q25). This research uses retention basin as one of the efforts in flood mitigation, reducing the amount of flood inundation that occurs by using embankment planning. Retention basin is a water structure that functions to collect rainwater and water runoff to reduce flooding. Retention basin is one of the important steps in the flood inundation that occurred in Magetan Regency using HEC-RAS 6.4.1 software analysis was 3,75 km2. The largest flood inundation occurred in Kartoharjo District with an area 1,31 km2.

According to Kastor and Sirakoulis (2009), calculating the number of workers according to the construction schedule is crucial because, without this consideration, the resulting schedule may not be effective and efficient. process used for construction project resources to reduce fluctuations (Waluyo & Aditama, 2017). This research compares labour allocation, duration, and labour wage cost budgets under several conditions. These conditions include actual project conditions, planning, and results after levelling using an auto schedule. In project planning, the fluctuations obtained are pretty sharp. After the auto schedule levelling, the manpower no longer experienced overallocation, but fluctuations between weeks were still relatively high. This can happen because the quantity of work and labour in the construction projects under review is not comparable to the effects of project delays. The results obtained from the comparisons analyzed on the X-storey building construction project are that the auto schedule does not change the initial planning duration, which remains at 133 days. There was a disparity of 0.02% in auto schedule planning costs from 1,098,345,000.00. Meanwhile, in actual conditions, the labour cost budget increased by 0.12% from IDR 967,880,000.00 after the auto-schedule levelling process. It can be concluded that before resource levelling is carried out, it is necessary to review project scheduling and accelerate the duration of implementation, specifically if construction projects experience delays and other factors, so as not to cause fluctuations caused by the uneven quantity of work over some time.","PeriodicalId":519042,"journal":{"name":"Sustainable Civil Building Management and Engineering Journal","volume":"104 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140987620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MRP method is carried out to accurately calculate the amount of material needed to avoid excessive material inventory levels. After the MRP method, the most optimal number of orders and the total cost required for each lot measurement technique are obtained. The results of this study show that the LFL technique produces the optimum number of orders for gelam wood, plywood, reinforcement, bendrat wire, and ready mix concrete.
