Abstract

Building maintenance is essential for ensuring structural sustainability, especially during the post-retention period when responsibilities shift to the owner. This study analyzes the influence of six technical factors—building design, maintenance frequency, material availability, weather adaptation, material quality, and quality control—on maintenance success. A quantitative approach with Structural Equation Modelling (SEM) was used, based on 50 expert responses. Results show all six factors significantly affect maintenance success, material quality was identified as the most dominant indicator within the technical factors construct, with a loading factor score of 0.784. Of the success indicators—cost, time, quality, user safety health and security, and durability—quality assurance is the most dominan with a loading factor score of 0.841. The model explains 61.8% of variance (R² = 0.618), demonstrating strong predictive relevance. These findings underscore the importance of integrating high-quality materials, applying strict quality control, and employing strategic planning. The study offers practical insights for building owners and contractors during the post-retention phase. Future research may expand on technological and environmental considerations for better maintenance outcomes.

Abstract

Construction projects heavily rely on labor, materials, and equipment to ensure timely completion, with materials being a significant cost component. This study addresses discrepancies between rebar inventory and material demand, which can disrupt production and delay project completion. This study aims to determine the rebar volume using Cubicost TRB and optimize the lowest requirement cost by applying the Silver-Meal and Wagner-Whitin algorithms. Detailed engineering data supports the application, ensuring rebar bends meet technical standards at beam, column, and slab intersections. Material planning incorporates project schedules, inventory records, and rebar volume data from Cubicost. This planning considered the minimization of ordering and storage costs. The results showed that the volume of rebar calculated using the Cubicost application was more accurate than the project's bill of quantity data. The use of the Cubicost application proved to be more advantageous, resulting in a 1% reduction compared to the project data. Then, the Silver Meal algorithm resulted in total costs that were 21% lower than those of the Wagner-Whitin method in minimizing overall inventory costs, particularly for high-demand rebar types such as D13 and D19. These findings highlight the importance of accurate inventory scheduling and selecting appropriate lot-sizing techniques to minimize costs and prevent delays. Future research can compare Cubicost TRB’s accuracy with other software and extend the Silver-Meal and Wagner-Whitin algorithms to other materials.

Abstract

Quality according to planning is one of the most important things in the successful implementation of each construction project. Quality factors when implementing building construction projects are very important to know, especially for construction service providers so that they can find out what factors affect the decline in building construction quality. This study aims to analyse the factors that affect the decline in the quality of building construction. This research was conducted by distributing questionnaires in order to obtain data which will then be analysed and discussed in this study. Respondents of this questionnaire are contractors and consultants. Seven factors are obtained that affect the decline in building construction quality based on the results of questionnaires and data analysis, namely equipment, materials, implementation, environment, cost, human resources, design. Furthermore, the data that has been obtained is tested for validity to ensure that the data obtained is valid and reliable testing is carried out to ensure that the valid data is also reliable. The data was analysed using the relative importance index analysis method with the results of the inaccurate design drawing variable which has the highest RII value of 0.908, then descriptive analysis and obtained the results of the design factor having the highest mean value of 3.511 which means that the design factor has the greatest influence on reducing the quality of building construction.

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

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.
