Abstract

A design and build (DB) is a method that offers several advantages, including accelerated implementation time and reduced costs. Nevertheless, the implementation of the DB method in local government projects in Indonesia is still constrained by a number of factors. The objective of this study is to identify the inhibiting and enabling factors in the adoption of the DB method in local government. This research approach employed a Delphi survey, which involved experts and practitioners. The data was collected through the administration of questionnaires. The study identified 15 key barriers to DB implementation, including a lack of supportive regulations, low literacy in risk management, and a lack of staff knowledge and experience in implementing DB methods. Furthermore, distrust and a preference for more familiar methods represent significant obstacles. In contrast, there were 20 enabling elements, which were divided into four main factors. These were regulatory adjustment, capacity building of users and service providers, effective management, and external support. Regulatory adjustments included adjustments to the DB tendering and contracting system and shared perceptions with the legislature. The capacity building of users and service providers encompasses pilot projects, individuals who possess a comprehensive understanding of DB, and the provision of sufficient financial resources. Effective management encompasses inter-organisational communication and knowledge transfer, as well as DB-related socialisation and training. External support encompasses public acceptance, stakeholder support, and favourable political, economic, and cultural conditions. The findings of this research indicate that in order to enhance the utilisation of the DB method within local government, it is essential to address the identified obstacles and to capitalise on the identified opportunities.

Abstract

The construction implementation system in the Mandala Mathika Subak Museum Revitalization project uses the cast in situ or conventional method including floor slab work. The implementation of floor slab work with the cast in situ method requires a long processing time and a lot of labor and costs incurred. In the construction of the building, the selection of work methods is very influential on the implementation time and cost. The selection of the right method will make the development efficient. One of them is the use of precast concrete such as half slab. In this study will compare conventional methods and half slab methods from the aspects of implementation time and cost, which is more profitable. The results of the comparative analysis of execution time and costs from the calculation of cast-in-situ and half-slab plates in the Revitalization Project of the Mandala Mathika Subak Museum show that using the half-slab method saves 33% in costs compared to the cast-in-situ method, with a cost difference of Rp. 552,730,037, and can accelerate the execution time of 43% or 19 days.

Abstract

In the construction, it must be able to be used according to its function so that it can be used for a long time. The concept of construction that has sufficient strength and allows for large spaces without affecting aesthetics has emerged in recent decades. A flat slab is one of the advances in the construction system of a two-way concrete plate that distributes the working load directly to the column element without using a beam. The use of drop panels can increase the strength of the plate by resisting the sliding style of the pons and reducing the negative moment reaction that occurs on the plate and column. In the analysis, the results used a flat slab with a thickness of 200 mm, with bones in the x and y directions at the focus of As D16-100 mm and As’ D16-200 mm, whereas in the columns of column directions x and y, the field part is mounted with As D13-100 mm and As‘ D13-200 mm. In the middle column of directions X and Y, use the bones of As D13-100 mm and As‘ D13200 mm. Used a drop panel of 300 mm. For the lift area, an L type column with dimensions of 450 mm x 450 mm is used. The bars used are TB1, TB2, B1, and RB, and the columns used are 500 mm x 500 mm and 400 mm x 400 mm. The planned foundation uses a cylinder-shaped pillar with a depth of up to 8 meters.

Abstract

This study examines the planning of high-rise building structures in Indonesia, focusing on the application of Special Moment Resisting Frame (SMRF) systems under seismic conditions. Situated within the Pacific Ring of Fire, Indonesia frequently experiences significant earthquakes due to the convergence of three continental plates. Previous research indicates that the design of high-rise buildings necessitates careful attention to dimensions and reinforcement to ensure structural strength and stability. The SMRF planning method, which applies the principle of strong column weak beam, has been analyzed across various case studies, including designs for office buildings, hotels, laboratories, and educational facilities.Furthermore, this study compares the structural performance using different concrete strengths, specifically 41.5 Mpa and 24.9 Mpa, in the construction of prison walling at the Kejati Detention Center. Through quantitative analysis and structural modeling using ETABS V.20 software, this research identifies differences in base shear and inter-story drift between the two concrete strengths. The findings provide insights into the effectiveness of higher-grade concrete usage and its potential impacts on the strength and structural quality of buildings. The implications of this research can guide practitioners in selecting the appropriate construction materials to enhance performance and cost-efficiency in high-rise building projects in Indonesia.
