Abstract

Planning material supplies well is very important in implementing construction projects to ensure smoothness and efficiency. Smoothness includes thorough planning, including ensuring materials are met as planned, while efficiency aims to reduce time and cost. In this study, material planning will be carried out using the Material Requirement planning (MRP) method, using three different lot measurement techniques, namely Lot for Lot (LFL), Economic Order Quantity (EOQ), and Period Order Quantity (POQ). 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. Meanwhile, for materials such as lubricating oil, meranti wood, randu wood, and nails, it is optimal to order using the POQ technique.

Abstract

Although all resources on a construction project have their respective roles, the availability of labour significantly impacts how far the project moves forward and is completed. 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.

Abstract

The world of construction is very dependent on technology, especially in the era of the industrial revolution which demands efficiency and competitiveness. The use of BIM (Building Information Modeling) technology supported by Autodesk Revit software enables more effective and efficient project planning and implementation. One application of BIM is in planning reinforcing steel requirements. To overcome material waste which often occurs due to less than optimal cutting of reinforcing steel, material management with a bar bending schedule and the use of BIM is an important solution. In the Satpol PP Building Construction Project in Bantul Regency by PT Quinad Bahana Indonesia, this new method with software was applied to correct cutting of reinforcing steel, reduce waste and increase construction efficiency. This research method includes data collection, 3D BIM modeling, comparing work volume using Autodesk Revit and conventional. After getting the reinforcing steel volume from the Autodesk Revit software, continue by entering the volume data into the BIM to obtain optimal reinforcing steel cutting patterns. The research results show that the use of Autodesk Revit software for column and beam work results in an overall difference of 11%. The volume resulting from Revit quantity take-off is less than manual analysis. Based on waste level calculations, the average value of waste level is 0.97%. This proves that the BIM is effective in reducing material waste on construction projects. Apart from reducing material waste, the BIM is also able to optimize reinforcing steel cuts.

Abstract

Construction cost estimate in construction projects requires high accuracy in calculating work volumes and applying unit cost analysis. Lack of accuracy in calculating the volume of work can result in inaccurate cost estimates, causing project budget overruns. This research discusses the use of 3D BIM planning concepts using Autodesk Revit software to help calculate volumes accurately, with the aim of reducing project budget overruns. Comparative analysis of cost estimates between the use of Autodesk Revit and conventional methods provides an overview of the efficiency and effectiveness of using BIM software in estimating construction project costs. The object of this research is the Satpol PP Bantul office construction project, with a focus on structural work. This research method includes data collection, 3D BIM modeling, calculating cost estimates based on the volume produced using unit cost analysis, and comparative analysis of cost estimates between the use of BIM software and conventional methods. Based on the research results, it found that the construction cost estimate for structural work from Revit had a value of IDR 862,330,518.59 and a difference of IDR 53,420,195.31. This shows that the use of the 3D BIM concept results in 5.83% cheaper calculations than conventional construction cost estimate methods.

Abstract

The development of the construction world is driven by the demands of meeting various needs, such as in this case study, namely the construction of the Bantul satpol PP Building to meet the needs of the legal apparatus. However, according to the United Nations Environtment Program in the Global Status Report for Buildings and Construction (2021) states that this development has a significant environmental impact, construction projects are responsible for 36% of energy consumption and 37% global CO2 emissions by 2020. Therefore, this research aims of achieving Greenhouse Gas Emission (GHG) efficiency using the Life Cycle Assessment (LCA) method. Data analysis was applied through the Autodesk Revit program to get the material schedule and LCA approach within the scope of Cradle to Gate using ISO 14040 and 14044 guidelines. The structure of foundations, slabs, columns and beams became the object of research because the constituent materials in the form of concrete and steel are considered as CO2 GHG contributors with the largest percentage, reaching 75% of the total emissions released (Luo et al., 2016). The analysis results show that the largest GHG estimate is located in the structural work of the Cradle to Gate scope which reaches 1,657,880.04 KgCO2eq with the most critical process unit which is the material production process unit. Thus, project construction management can look for the best alternatives related to material selection or methods in the material production process that can reduce GHG emissions. This research can be applied to create a sustainable construction.

Abstract

Flooding is a natural event that often occurs in Indonesia. 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. The design of the Kartoharjo Retention Basin in Magetan Regency can reduce the flood inundation area by 22% to 2,94 km2.

Abstract

In construction projects, cost and duration are important aspects but there are several factors that become obstacles. With these constraints, the project needs to organize its project management to keep it running according to the contract. The method that can be used to manage these obstacles is TCTO (Time Cost Trade Off). There are three scenarios used in this study, namely the addition of working hours, the addition of labors, and the combined (addition of working hours and labors), using the help of Primavera P6. This research aims to analyze the estimated total duration and cost obtained after optimization, compare the total duration and cost obtained before and after optimization, and recommend the most economical alternative among the scenarios carried out. The results of the optimization analysis carried out using additional working hours (scenario 1) are 611 days and an increase in costs; while with additional labors (scenario 2) are 632 days and a decrease in costs; and with combined (scenario 3) are 611 days and a decrease in costs. The most economical alternative from this study is to use scenario 2 because it reduces the duration and cost of the initial cost budget plan of the project.
