Abstract

The foundation is a building structure located under the building. The foundation cannot be separated from the building structure because it is a structural part whose function is to transmit the load from the upper structure to the supporting soil layer beneath it to prevent collapse of the soil or settlement of the structural system. This research compares the costs and time required for pit foundation work with site foundations, with the aim of finding out whether the planned costs and implementation time have the same efficiency or not. The purpose of this research is to find out how much bearing capacity there is in the well and site foundations, how much costs are needed to plan the well and site foundations, and how long the implementation time is required. The method used in this research is a comparative study (Comparison). The comparative or comparison method is research that uses the technique of comparing an object with another object. The objects being compared, the comparative method is carried out to compare the similarities and differences of two or more facts and properties of the object being studied. From the calculation analysis, the bearing capacity of the well foundation was obtained at 1950 KN with a cost of IDR 469,046,724 and an implementation time of 78 days. Meanwhile, for the site foundation, the foundation bearing capacity was obtained at 451.11 KN at a cost of IDR 174,598,298 and a construction time of 56 days.

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

As the development of infrastructure progresses rapidly, concrete technology is also required to continuously improve. Numerous studies on concrete technology have been conducted to meet these demands, one of which is the innovation of Reactive Powder Concrete (RPC) with 15% silica fume and 30% quartz sand. One application of reactive powder concrete in structural element design is the concrete slab. A concrete slab is a thin structure with a horizontal plane and loads perpendicular to the plane of the structure. Concrete slabs are designed to withstand bending loads due to bending moments caused by heavy loads, which are a combination of dead loads and live loads. Therefore, it is necessary to conduct flexural performance tests on concrete slabs to determine their ability to withstand loads that cause bending moments on the slabs. The research aims to compare the experimental test results with numerical analysis of the flexural performance of reactive powder concrete slabs with varying thicknesses and span length - width ratios. The test specimens for varying thicknesses measure 70 cm x 30 cm with thickness variations of 4 cm, 5 cm, 6 cm, and 7 cm. Meanwhile, the test specimens for varying span length-to-width ratios have a thickness of 5 cm and a length of 70 cm with span length-to-width ratio variations of 2,5; 2,7; 2,9; and 3,1. The research method used is non-linear finite element analysis with ATENA Engineering Červenka Consulting software. This research includes verification of experimental test results with numerical analysis results in terms of both maximum load and maximum deflection. The verification results of numerical analysis using ATENA Engineering Červenka Consulting software with experimental testing on both thickness variations and span length - width ratio variations show a corresponding trend curve based on the load-deflection graph, with the difference in maximum load and maximum deflection values between experimental test results and numerical analysis results being below 10%.

Abstract

Flexible pavement is the most commonly found type of road pavement in Indonesia. One asphalt mixture used in road construction is the Lataston Hot Rolled Sheet. The quality of road pavement can be enhanced by carefully selecting materials such as asphalt, aggregate, and filler. Filler plays a crucial role in asphalt pavement mixtures, and fly ash, containing pozzolanic elements, can be used as it fills voids and binds the mixture effectively. This research investigates the use of fly ash as a filler in the HRS-WC asphalt mixture, aiming to determine the optimum asphalt content, the best filler content, and the impact of fly ash as a filler on the performance of asphalt road materials in the Lataston Hot Rolled Sheet mixture (HRS-WC). The study employs the Marshall testing method in accordance with the 2018 General Bina Marga Specifications (Revision 2) The results of research on Marshall characteristics, obtained an optimum asphalt content value of 7.5% and an optimum filler content value of 1.35%. The addition of fly ash as a filler to the HRS-WC asphalt mixture increases the stability, durability and stiffness of the mixture by filling empty spaces, increasing density, reducing air voids and binding the asphalt mixture. However, excessive use of fly ash can make the mixture too stiff and reduce the flexibility of the pavement.
