Abstract

A job on a construction project can affect delays throughout the project. Every construction project has a specific plan and schedule for when to start when to finish, how to schedule, and how to provide resources. There should be no delays in implementation because they will result in increased project costs. However, there was a delay in the performance of the lecture building construction project with the Faculty of Engineering UPN "Veteran" East Java. The methods given in the discussion to determine the factors that influence the occurrence of delays are the Fault Tree Analysis (FTA) method and the Obtain Cut Set Method (MOCUS). Work items that experienced delays were structural, architectural, and MEP work. There are three top events known through FTA analysis, namely delays caused by design changes and wrong drawings, which are factors causing delays from service users. The dominant factor causing delays in structural work is the difference in elevation with elegant buildings and a need for more attention to structural safety. This problem occurs in the top event factor of service users. The service users referred to in scientific research are the owners and/or planning consultants. From the results of a quantitative Fault Tree analysis, the reliability value of the structural work is 0.861. In this case, the structural work experienced a delay of >10% with a Reliability value below 90%, so the contract was declared critical.

Abstract

Terlambatnya suatu pekerjaan dalam proyek konstruksi dapat berdampak pada keterlambatan proyek secara keseluruhan. Penelitian ini mengambil studi kasus pada Proyek Pembangunan Gedung Laboratorium Biologi UNESA Kampus Ketintang yang direncanakan berjalan selama 180 hari kalender atau 26 minggu. Pada minggu ke-18, mulai terlihat progress proyek mengalami keterlambatan sebesar 6,40% dengan sisa waktu pelaksanaan proyek 8 minggu. Penelitian ini bertujuan untuk menganalisis waktu pelaksanaan proyek agar dapat lebih cepat dari target waktu rencana awal. Analisis percepatan pada penelitian ini dilakukan dengan menggunakan dua metode. Analisis pada tahap pertama, dilakukan menggunakan metode fast track. Setelah dilakukan analisis, waktu proyek awal yang semula 213 hari dapat tereduksi menjadi 191 hari. Biaya total proyek berkurang menjadi Rp. 13.184.966.600,00 (turun 1,55% dari total biaya proyek awal). Analisis percepatan tahap dua dilakukan untuk mengejar target waktu penyelesain proyek. Setelah dilakukan percepatan tahap kedua menggunakan metode crashing penambahan jam kerja (lembur) selama 3 jam, waktu proyek setelah percepatan yaitu 191 hari dapat tereduksi lagi menjadi 177 hari. Biaya total proyek mengalami penambahan menjadi Rp. 13.184.966.600,00 (naik 0,11% dari biaya total proyek setelah percepatan tahap 1). Sehingga, biaya total proyek yang semula sebesar Rp. 13.392.456.000,00 menjadi Rp. 13.184.966.600,00, terdapat selisih sebesar Rp. 206.334.966,00 (turun 1,54%).

Abstract

Roads are a land transportation route that has been used since ancient times as a means for people to move places using existing transportation. In road construction efforts, it is necessary to have Standard Operating Procedures, or SOPs, that are used with the aim of improving worker performance, ensuring road quality, increasing profits, and company development. SOP is a method or work flow that has been standardized, is used as binding and directive instructions, and covers things from an activity that has steps or procedures. Currently, there are still many road work projects that are carried out without paying attention to existing SOPs, and this means that the quality of the concrete roads being made does not comply with applicable standards, which means that some parties may experience losses. There needs to be a good understanding of how SOPs comply with standards so that they can produce concrete of maximum quality. This writing was prepared using an analytical method using a literature study that refers to the Indonesian National Standards (SNI) and the PUPR Ministerial Regulation (Regulation of the Minister of Public Works and Public Housing).

Abstract

A construction project is a complex and exciting process, starting from planning and design, through to implementation and finishing. The process of building a construction project always has risks at every stage of its implementation. To prevent and minimize risks that could cause work accidents and losses on the project, it is necessary to carry out a work accident risk analysis on the project. This research carried out a work accident risk analysis on the Joint Lecture Building and FISIP Laboratory Phase 2 UPN "Veteran" East Java Construction Project using the FMEA method. The aim is to identify the risks of work accidents that could occur in building construction projects and to determine the severity level, incidence rate, detection level, and risk priority number (RPN) in these projects. The results of the research show that the risk of work accidents with the highest Risk Priority Number (RPN) value occurs in foundation structure work with the risk of workers being injured by these materials with RPN value of 174,857.14. Work on strengthening foundation structures with the highest RPN values requires the greatest attention and risk control measures.

Abstract

Material inventory in construction projects is something that needs to be managed because it affects the smooth running of a construction project. To overcome this problem, material scheduling was carried out based on the Material Requirement Planning (MRP) method using the Economic Part Period (EPP) lot size technique and the Least Unit Cost (LUC) lot size technique. This research aims to produce material planning processes and results. MRP is a scheduling method to find out the material and quantity of material needed, as well as when the order will be placed. The calculation results obtained using the MRP method are that the EPP lot size requires a total material inventory cost of IDR 20,847,682,834, while the LUC lot size requires an inventory cost of IDR 20,851,272,531. The difference in total costs is IDR 3,589,697 so the EPP lot size is more economical compared to LUC.

Abstract

The condition of work accident risk is a critical factor that needs to be taken seriously. Related to the construction of the Ciputra Hospital Project located on Jl. Made Selatan - Citraland Surabaya, the Ciputra Hospital project is planned to be built on nine floors with a building area of 23,000 m2, which will allow for various occupational accident risks. So, a risk analysis is needed to identify hazards that can occur. In this study, data collection was carried out through interviews and also distribution questionnaires. Questionnaires are used to find probability and severity scales, and questionnaires are distributed to project expert staff. After obtaining the results from the questionnaire, a risk assessment is carried out by finding the probability index and severity index and then determining the category with the risk matrix. After determining the category, the analysis was carried out using the bowtie method. The result of this study is to determine the most dominant risks, namely workers being punctured by sharp equipment when installing formwork, workers falling from a height when installing formwork, and workers being hit by a bar bender machine when forming. After analyzing using the bowtie method, it was found that the causes of the risk of accidents that occurred included workers in a tired condition, lack of concentration, and carelessness, incomplete use of PPE, undisciplined workers at work, no safety at the job site, bad weather, inexperienced workers, poor machine conditions.

Abstract

BIM technology in the construction world is growing. However, the application of BIM in Indonesia has not been carried out thoroughly. BIM technology can help quantity take off work that affects the success or failure of a project. BIM can reduce the error rate of quantity take off planning calculations compared to manual calculations. Tekla Structure is one of the software developments of BIM that can produce quantity take off building output along with 3D visualisation. This research conducts 3D modelling and discusses the comparison of quantity take off using BIM-based software Tekla Structures with a recap of the manual calculation contained in the initial Bill of Quantity for the X Building Project planning. This difference can be used as a consideration for the application of BIM in the initial calculation of project planning. The percentage difference obtained for the pile cap resulted in concrete volume deviation of 0.69% and -19.1% for reinforcement volume. The spun piles work resulted in a concrete volume deviation of -0.8% and reinforcement volume of 8.45%. In the calculation of column work, the deviation value for concrete volume is 3.14%, while the volume of reinforcement is -12.2%. The results of the BIM quantity take-off are deemed more reliable due to the 3D visualization of BIM objects and the ability to adjust the detail of work elements.
