Abstract
Current technological developments greatly influence construction projects, both in material procurement and contract models. Specifically for dealing with natural disasters with short recovery times, a Design and Build contract model is used. In the Pangsan Bridge Construction Project, the contractor procured precast concrete beams (Girders) which were produced at the factory and the installation process was carried out at the project. This contract is determined by direct appointment and this Regulation has been issued in PERPRES No. 54 of 2010 Article 38 Paragraph 1 stipulates that direct appointment of 1 (one) provider of Construction work/Other Services can be done in the case of exclusive circumstances; and/or Procurement of special goods/specific construction work/other services of a special nature. The precast concrete girder beam measures 0.65 m x 0.90 m with a length of 15.6 m, and is molded into 3 parts whose strength has been calculated. In terms of processing time, it is faster and costs more than conventional concrete. With production outside the project completion time is 1,5 months faster at a higher cost of 4,5 billion The length of conventional concrete is due to the implementation method which must be sequential and interrelated with a smaller cost of 3,8 billion So to meet the short time, the precast method is used even though it costs more.
