Abstract

Building construction requires careful planning and accurate cost estimates. One effective method for calculating costs is the Life Cycle Cost (LCC), which includes the total costs that will be incurred throughout the planned life of the building. Financing consists of planning and construction costs, called initial costs, operational costs, maintenance costs, and demolition costs. This study focuses on the Balai Pelatihan Vokasi dan Produktifitas (BPVP) Sorong City office building, which is undergoing a renovation process. The challenge lies in determining the Life Cycle Cost (LCC) for building maintenance. Analysis of routine and periodic maintenance cost is the method used, with data collected through interviews and data collection from related parties. This study aims to calculate the total cost of the Life Cycle Cost (LCC) and provide recommendations for more efficient cost management in the process. There are four components that underlie the Life Cycle Cost, namely the initial cost or construction cost of Rp.4.703.149.690,60, the operational cost of Rp.128.166.180.245,80, the maintenance cost of Rp.15.698.538.615,10, and the demolition cost of Rp.1.504.632.833.

Abstract

The project seeks to promote the National Economic Development (PEN), specifically targeting the enhancement and advancement of economic activities on Sumatra Island. One of the current projects is the construction of the Sicincin - Padang Toll Road Section (STA 0+000 - 36+600) of the Pekanbaru - Padang Toll Road. This segment of the highway is a component of the Trans Sumatra highway network on Sumatra Island. The bearing capacity and settlement design of the spun pile foundation at the pile slab STA 7+443 - STA 7+569 Sicincin - Padang Toll Road were recalculated based on soil investigation data derived from SPT (Standard Penetration Test) results, subsequently compared with the findings from the PDA Test (Pile Driving Analyzer) conducted in the field. Soft soil issues were identified at STA 7 + 443, leading to the formation of fissures and landslides. The issues arose from the interaction between a pile foundation plate and the capacity of a revolving pile foundation. The objective of the study is to determine the bearing capacity and settlement of the rotating pile foundation at STA 7 + 443 - STA 7 + 569 using Standard Penetration Test (SPT) results and to compare these findings with the field data obtained from the Pile Driving Analyzer (PDA) test. The analysis conducted involved the adjustment of the N-SPT value utilizing tables and graphs in compliance with SNI 1725-2016, SNI 8460-2017, and SNI 4153-2008. The settlement assessment reveals the most significant discrepancy in the Meyerhoff Method compared to the PDA Test, amounting to 5.32%. The pile's settlement is within the allowable limit of 60 mm; hence it is deemed safe.

Abstract

The Intergovernmental Panel on Climate Change (IPCC), one of the United Nations' bodies tasked with evaluating climate change science, has reported that humans have experienced temperatures 1.2 degrees Celsius higher than usual, and in the past decade, sea levels have risen almost three times. One of the solutions to this issue is to implement environmentally friendly construction. Asrama Al-Hikam Depok is one of the ongoing construction projects, and this research will examine whether this project applies environmentally friendly construction in its planning. Therefore, it is necessary to identify green building criteria for this dormitory's construction. The method used to identify green building criteria is the Greenship New Building Ver 1.2 method, and the cost estimate is calculated using the latest AHSP method. The results of the criteria achieved by the Asrama Al-Hikam Depok project received a score of 36 out of 101 points, or 36% of the criteria achieved. There are several criteria that can be recommended to increase the rating, provided that the criteria are applied to the building, and of course, there is an additional cost from the initial building budget. The conclusion of this research is that the Greenship rating achieved at the Asrama Al-Hikam Depok project is a bronze rating and can be raised to a silver rating by applying six criteria: Make a statement for temperature and humidity surveys; have a solid construction waste management SOP; have a liquid construction waste management SOP; add lux sensors to workspaces; install CO2 and exhaust sensors in the multipurpose room; install solar panels. The additional cost that can raise the rating of this building by one level above the achieved rating is Rp. 12,298,330.

Abstract

The presence of construction joints is an inevitable aspect of field concrete casting. These joints occur when fresh concrete is poured over hardened concrete, which can impact the strength and integrity of the concrete structure. This study aims to evaluate the placement of concrete joints according to SNI 2847-2019, which recommends placing them at one-third of the span of the beam. Testing was conducted on unreinforced concrete beams with two different joint locations. The concrete used had a water-cement ratio (w/c) of 0.5 and a maximum aggregate size of 25 mm, with the mix design following SNI 7656-2012. The test results indicate that joints placed at one-third of the span exhibit better flexural strength compared to those located at the span's ends. The average flexural strengths of beams without joints, those with joints at one-third of the span, and those with joints at one-third of the end span are 1.95 MPa, 1.56 MPa, and 0.98 MPa, respectively. These findings support the SNI 2847-2019 recommendation for placing concrete joints at one-third of the span of the beam.

Abstract

Cracking was observed on pier head P85-84 S of the JORR W1 Kebon Jeruk toll road, caused by an increase in span length and loading conditions that exceeded the original design specifications. This resulted in bending moments greater than those accounted for in the initial design, prompting the need for a structural capacity evaluation of the pier head. This study aims to assess whether pier head P85-84 S remains capable of withstanding the applied loads. The evaluation was conducted by analyzing the required reinforcement area, cross-sectional dimensions, and nominal moment capacity in comparison to the ultimate moment, using SAP2000 software. The analysis revealed that the pier head's capacity is inadequate. Under standard loading conditions, deficiencies of 1D19 and 5D19 were found in the bottom support and mid-span reinforcement, respectively. Under actual loading conditions, the reinforcement deficiencies increased to 2D19 at the bottom support and 8D19 at mid-span. Additionally, the comparison between the nominal and ultimate moment showed that the ultimate moment caused by the applied loads reached 71.12 ton·m, while the nominal moment was only 44.01 ton·m. These findings indicate that the current structure is insufficient to resist the existing loads. Therefore, structural strengthening is required, which may include the use of Fiber Reinforced Polymer (FRP), steel plate bonding, or external prestressing.

Abstract

Infrastructure serves as a fundamental public service provided by the government to meet community needs, with its development significantly impacting societal welfare. Project delays and instability often result from inadequate planning. This research aims to evaluate the effectiveness of applying the Critical Path Method (CPM) and the Program Evaluation and Review Technique (PERT) in determining the construction duration of the Building X project. Both methods are project management tools designed to improve time efficiency in construction activities. Calculations were performed using data provided by field personnel. While CPM utilizes a single time estimate, PERT incorporates three-time estimates to account for variability. The outputs of this study include the total duration required to complete the project and the identification of its critical path. Based on the analysis, the CPM method estimated a project duration of 37 weeks, whereas the PERT method estimated 38 weeks.

Abstract

One alternative to replacing traditional red brick is lightweight brick, which is commonly used as a wall construction material. One of its main advantages is its light weight, which can help reduce overall construction costs. The reduced weight of the wall material allows for a decrease in the volume of structural elements needed. However, with advancements in material technology, there is a need to further improve the efficiency of lightweight bricks in terms of material usage and the quality of the masonry, particularly its shear strength. This research aims to analyze the optimal fiber placement composition in Cellular Lightweight Concrete (CLC) bricks to enhance the bond strength between bricks compared to that of standard lightweight brick masonry. The test specimens were constructed by assembling wall segments using lightweight bricks measuring 7.5 cm × 20 cm × 60 cm. Compressive strength and horizontal shear strength tests were then conducted on the CLC brick wall assemblies. The results showed that the lightweight bricks had a compressive strength of f'c = 1.07 MPa. The horizontal shear strength without fiber reinforcement was fg = 0.09 MPa, while with fiber reinforcement, it decreased to f'g = 0.06 MPa. Crack patterns were observed at failure displacements of 0.33 mm (non-fiber) and 0.5 mm (with fiber). These findings indicate that the use of GRC fiber in lightweight brick walls resulted in lower horizontal shear strength and displacement performance.

Abstract

Sheikh Mohammed bin Zayed Road (MBZ), formerly known as Jakarta-Cikampek Road (Elevated) and managed by PT. Jasa Marga, is a barrier-free road that must meet service quality standards to ensure user comfort and safety. The study aimed to analyze the satisfaction of 100 respondents using the Importance Performance Analysis (IPA) method. The results of the study showed a 92.05% correlation between interest levels and performance, indicating less satisfactory road performance. The Cartesian diagram identifies a critical service attribute with the highest average score as the available and clearly visible road security fence (4.36), while the less important attributes are officers being friendly and polite when on duty (3.94). For performance, the attribute with the greatest score is a clear sign before entering a curve; the user feels safe (4.77), whereas the attributes with the lowest score are convenient toll road surfaces when crossing (roads are considered flat and non-wavelets, so speed does not decrease) (3.02). Attributes included in the Key Priority Quadrant are convenient toll road surfaces when crossing (roads are considered flat and non-wavelets, so speed does not decrease), which require solutions such as routine inspection and maintenance, better paving technology, periodic resurfacing, and strict quality control.

Abstract

Building Information Modeling (BIM) is a technology-driven approach that integrates and manages information from all aspects of a construction project within a comprehensive 3D model. Using BIM-based planning makes the process more efficient, helps minimize over-budget issues, and simplifies volume calculations. There are various BIM software tools such as Autodesk Revit, Tekla Structures, and others, each with its strengths and weaknesses. In this study, the researcher analyzes the Quantity Take-Off (QTO) of the main column reinforcement using Autodesk Revit and Tekla Structures. The results of the rebar QTO from the outputs produced by both software tools showed a total deviation of 0%, indicating that both were equally accurate in generating QTO. This suggests that regardless of the software choice, the accuracy in modeling and managing 3D data remains reliable if the modeling process is done correctly and precisely. Furthermore, QTO calculations using BIM software proved to be more effective, with a result difference of 0.132% compared to conventional methods, as BIM facilitates data processing and automation of changes, directly linked to the 3D model. This ensures that any change in one task automatically adjusts related tasks, thus speeding up the planning and execution process in construction projects.

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.
