Abstract

The procurement process in construction is quite complicated with its various methods. One of them, design and construct contracting, which often used, is one that has an advantage of saving time and money. However, for companies without sufficient capabilities to carry out procurement, the design construct contract method also requires expert assistance in the process. To meet the construction procurement process requirements, one workable solution is that the company collaborates with a university for its factory construction development. The relevant academicians have expertise to solve problems in procurement process. The academician team was collecting appropriate data and then evaluating it to give suggestions on the construction procurement process. The method used was a simple comparison of the price proposed by the contractor to the owner estimate which was then calculated based on the Indonesian Regulation by the Minister of Public Works and Housing no. 28/PRT/M/concerning the unit price analysis that used as reference. Prices for materials, tools, and wages referred from Indonesian unit price journal references. The result of the evaluation was to determine the contract winner based on price and technical design aspects within company budget. During the evaluation process, clarification was made regarding the proposed design, construction method and quality of the proposed material to match the technical aspects of the design. The price evaluation process which was carried out in a short term has assisted the company in carrying out its construction procurement process. In the long run, cooperation can be developed in the form of human resource training so that the company can develop independently in carrying out the construction procurement process. Keywords: construction procurement, community service, owner estimate

Abstract

Based on the World Bank publication in 2019, one of the strategies to improve disaster financial resilience is the availability of loss estimation data. As one of the vulnerable countries affected by earthquake disasters, Indonesia does not yet have a widely used pre-disaster estimation model. Model adoption is one of the strategies used to improve disaster resilience in Indonesia. The HAZUS method is a model FEMA (Federal Emergency Management Agency) developed to estimate earthquake losses in the US. The adoption process in Indonesia requires adjustments to the EDP (Engineering Demand Parameter) used in the HAZUS model. The EDP in the HAZUS model consists of capacity curves, fragility curves, and repair cost coefficients. The statistics of buildings affected by earthquakes in Indonesia from 2000 to 2020 show that residential houses are the most affected buildings. This study aims to obtain comparative results of the HAZUS model structural element loss estimation with modified data of local capacity curve pushover results in Indonesia. The study was conducted by performing a pushover analysis on a case study of a residential building to obtain a capacity curve. In this study, the EDP analyzed was only the EDP of the capacity curve. The case study was conducted at housing cluster X in West Bandung Regency, West Java, using house type T94/120 as the case study structure. The results of the capacity curve comparison show that the capacity curve of the local house from the pushover analysis has lower stiffness and ductility. The comparison of loss estimation for single hazard scenarios shows that the modified curve method has the most conservative loss estimation than HAZUS in the hazard of earthquake return periods of 100, 250, 500, and 750 years. The annual loss estimation shows that the modified capacity curve provides the most conservative or 37.5% larger in annual loss estimation.
