|dc.description.abstract||Construction disputes occur frequently and are increasing daily in turnkey (Engineering, Procurement, Construction, EPC) projects. The major reasons resulting in the disputes are the characteristics of turnkey projects that are very different from traditional projects. Turnkey projects usually have vast range of scope and are more complicated since engineering design and procurements are also included in the contract. Meanwhile, responsibilities and work scope are usually defined vaguely in the lump-sum turnkey contracts. Thus, many construction claims arise due to adjustment of prices indices, extension of time, contract scope, construction defects, standards of acceptance, change of laws, and payment conditions.
This research focuses on collecting and categorizing contractual clauses of historical power plants that are advantageous to the turnkey contractor if disputes occur. Yet due to the client is the drafter of contract and there are fewer beneficial clauses for turnkey contractor, the Conditions of Contract for EPC/Turnkey Projects, i.e., the Silver Book, of International Federation of Consulting Engineers (FIDIC) is incorporated in this research. Consequently, the major purpose of this research is to provide the turnkey contractor with a reference to claim at various stages such as planning, tendering, construction, and commissioning of a power plant project.
The research classifies contractor’s construction claims into fourteen types and compensation documents into eight types for power plant turnkey projects. Corresponding necessary documents are listed for each of the construction claims. Expert interviews were also conducted to verify the validity and necessity of the documents. Results of this research provide a useful reference for turnkey contractors to avoid mistakes and to increase profits when dealing with similar projects in the future.
