Abstract

Implementation method plays a vital role in the world of construction because it is related directly to the project scheduling. In apply on implementation method, both sefety factor and effectiveness of work must be identified. The purpose of the analysis is to determine the behavior of the girder of a bridge implemented using innovative methods and to determine the safety factor during the implementation. The required data were the height of girder is 2.1m and width 0.7m. Referred to SNI 1725 Loading for bridges, and controlling structures reffered to SNI T-12-2004 (Concrete Structure Planning for Bridges). The analysis began by determining the geometry dimensions of the girder, STAADPro software was used for modelling and Microsoft Excel was for analyzing. The results of the analysis show that innovative method is safe to implement, the stresses that occur do not exceed the allowable stress; the safety factor shows all numbers more than 1, indicating if innovative method is safe. Keywords:Innovative modeling, Launching girder, Safe implementation, Safety factor

Abstract

AbstractThe idea of green building is adopted in residential dwellings to reduce environmental concerns by enhancing the environmental quality that impacts the health of building occupants and the surrounding environment. The application idea of green buildings is to address ecologically friendly features, which may be accomplished utilizing the Greenship Rating Tools evaluation requirements for residential construction. Prior to the building of housing, the most significant feature of this thesis is to conduct a technical and financial feasibility analysis. The Malang Residential Home data utilized in this study will be constructed on a 2-hectare plot with three house types: 48/66, 70/84, and 80/112. The necessary information consisted of a site plan, home design drawings, house technical specifications, and Malang's basic unit pricing for the 2018-2019 fiscal year. The evaluation of technical feasibility will be based on three parameters: BBC, BFC, and GBC. The financial viability will be evaluated using four parameters: NPV, BCR, IRR, and PBP. Additionally, the sensitivity would be examined based on variations in the proportion of capital, as well as an increase or decrease in the project's income and outcome. The research determined the technical feasibility of BBC to be between 60 and 75 percent, BFC to be between 0.60 and 1.0%, and GBC to be greater than 10%. The satisfaction of Parameter Greenship Rating Tools was awarded scores ranging from 3542 to 3542, placing Malang Residential Housing in the silver category. The financial feasibility analysis yielded NPV of IDR 1,382,745,228; BCR of 1.02; IRR of 59.75 percent; and PBP of 1 year and six months. Due to the sensitivity of the project's income and outcome to its viability, it was determined that the project was viableKeywords: green building, technical feasibility, financial feasibility
