Abstract

Every construction is expected to run well and will be completed in accordance with the planning. Therefore, project quality control is needed. Project quality control is extremely useful for one-time development so that the building can achieve its predetermined quality and standards. The purpose of this study is to find out the quality control system of reinforced concrete of upper structures on Columns, Beams, and Plates and whether the quality results of the reinforced concrete structure can meet the specified requirements. The data used in this study were the results of concrete compressive strength tests and steel reinforcement tests that had been carried out in the laboratory. This research was needed to minimize delays and costs so as not to miss the predetermined quality and standards. This research used the AS/NZS 4360 calculation method in which the analysis was carried out by taking into account the level of risk of the probability that occurs and the impact on costs, where the quality applied must be in accordance with the RKS that has been set on the project, the calculation was carried out using Excel in accordance with the formula to determine the level of risk in each structural work. The data were collected by distributing the questionnaire to each individual where the questionnaire contained work items to be analyzed from the division. The calculation analysis has obtained the result of the risk level for each structural work, column work worth 5.20, beam work 5.97 and floor plate work worth 6.00 which means that the work of the structure has a moderate level of risk. Keywords: Quality Control, Construction Implementation, Risk Factors, AS/NZS 4360.

Abstract

Building Information Modeling (BIM) software commonly used in Indonesia to calculate cost estimates includes Autodesk Revit and Cubicost. Previous studies have shown significant differences comparing the estimated cost of structural work in Autodesk Revit with conventional methods. Further study is needed to compare Autodesk Revit with Cubicost in the same project, with the purpose of knowing the difference in the estimated cost of structural work. The object of this study was the Urban Homes Residential Apartment construction project by reviewing the upper structure. The chosen research strategy was in accordance with the case study objectives. The process begins with the preparating of the WBS (Work Breakdown Structure), designing the BIM 3D, calculating the estimated structural work cost resulting from quantity takeoff using work unit price analysis, and analyzing the estimated cost comparison between Cubicost and Revit BIM software. Based on the analysis results, the estimated cost of building structures using Cubicost is Rp 80,485,995,692, - and has differences of ±13.1% compared to using Revit.

Abstract

A project is an activity in which implementation is limited by time and resources. Every project planning must pay attention to the effective and efficient value so that the project can run well and achieve maximum results and quality as planned. Technology is increasingly used including in the construction sector. The use of Building Information Modeling (BIM) technology is one of the technologies that is widely used to minimize the need for costs and work time and can integrate information about the project directly to the various parties involved. This research was conducted by planning using the 3D BIM concept to see the results of the application of technology on the upper structure work and comparing the results of the calculation of the cost of the upper structure work carried out using the BIM method and the conventional method on the Urban Signature Apartment - LRT City Ciracas, East Jakarta. The research method used involved collecting project data includes shop drawings and material specifications. Then, 3D modeling was carried out using Autodesk Revit software, and existing data was analyzed to determine the volume of work and the total cost incurred. From the calculations, it can be concluded that using 3D BIM technology with Autodesk Revit software shows 6.69% difference compared to conventional methods.

Abstract

LPS is a project management system designed to control production in terms of project implementation schedules, aiming to enhance the relationship between work, performance, and productivity within a construction project. The object of this study was Building Project No. 34, which experienced delays in work on the lower structure, which caused delays in the duration of project implementation on subsequent work. In week 30, the project encountered delays in the lower structure work, resulting in a planned weight of 0.4920%, but the actual weight was only 0.4427%. Therefore, Building Project No. 34 tries to apply the LPS method, which is expected to improve project time performance. The study examines how LPS is used, what hinders it, and how to fix those issues in the No. 34 Building project. This study employed a questionnaire-based analysis of inhibiting factors and a time performance analysis. The results of the time performance analysis in week 30 were 0.3%, and in week 31 it was 0.2%. Using this planning simulation, the work could be completed on time or ahead of schedule (S Curve). There are a few things that make it hard to use LPS effectively: not having the right technical skills for it; believing that current technology is good enough that there is no need to implement LPS; not having clear standards and guidelines for its implementation; not being clear about each participant's roles, responsibilities, and functions; and lack of management involvement in providing motivation, training, and supervision, as well as discipline so that work is late.

Abstract

Natural disasters are recurring challenges experienced by countries worldwide, including Indonesia. One of the most common natural disasters in Indonesia is landslides, which frequently occur in various regions each year. Soil plays a critical role in construction, as stable and strong soil conditions are essential for structural integrity. However, poor soil conditions are often encountered, particularly on sloped terrain, increasing the risk of landslides. This study aims to analyze the Safety Factor (SF) of a slope using software based on the Limit Equilibrium Method (LEM). The SF value serves as a reference for further analysis; when SF < 1, reinforcement is required to support the applied loads. The slope stability analysis in this study yielded an SF value of 0.52. Based on this result, two reinforcement methods were evaluated: Retaining Wall and Corrugated Concrete Sheet Pile (CCSP). The analysis indicated that the Retaining Wall failed to adequately support the slope. In contrast, the CCSP reinforcement provided sufficient stability, with a Safety Factor of 1.587. Therefore, the Corrugated Concrete Sheet Pile (CCSP) is recommended as a safe and effective slope reinforcement solution.

Abstract

The problem of delay remains a major challenge in the construction world. During the implementation of construction projects, delays are often caused by obstacles or unplanned problems. Delays lead to the duration of project execution not as planned in the work contract. Many ways are done to overcome project schedule delays such as the crashing time acceleration method and the Last Planner System (LPS). The crashing method is carried out by accelerating the duration of project completion by carrying out three systems, namely increasing manpower, changing work time (shifts) and adding work time (overtime). Meanwhile, the LPS is a planning system based on collaboration, integrated commitment between works by involving people who are directly responsible and understand the work in a production unit. This study aims to analyze the acceleration of time with the Crashing method and with the LPS then compare the effectiveness of time acceleration between the two methods. Case study from the Pilot Scale Product Development Facility Building (Building No.34). The problem is what level of efficiency in both methods of time acceleration will be analyzed. The implementation of crashing with alternatives shift work reduces the project duration by 22 days, whereas the simulation of the LPS increases the actual weight compared to planning. The difference between the two method is that the crashing method is applied after delays occur, while the LPS accelerates work and increases productivity by utilizing continuous team collaboration.
