Abstract
A project delivery method (PDM) and project contract strategy (PCS) are two critical factors for project success in construction industry. Currently, there are several options available for them in the construction industry, with several innovative PDMs and PCSs emerging along with the development of the industry. This paper maintains that the PDM should be designed in combination with the PCS given their close relationship. This paper focuses on the design of project delivery and contract strategy (PDCS), with the aim of developing a conceptual framework for the PDCS design. The design process is divided into two stages: preliminary design and detailed design, taking engineering design as a frame of reference. In the design process, the value-added analysis of project objectives is adopted as a tool to make decisions at different stages. The framework proposed in this paper is intended to provide a more distinct and direct path to improving PDCS selection or design, as well as enhancing the reliability of decision-making.
Highlights
According to the data released by the National Bureau of Statistics of China, the total output value of the national construction industry in 2017 reached 213954 billion yuan, with a 10.5% year-on-year growth [1]
DBB or DB, as a fundamental project delivery method (PDM), will be selected in the preliminary design stage, as a basis for the detailed design. en in the detailed design, the most proper variant will be selected or a new variant will be designed based on DB or DBB according to the result of the first step, and the contract strategy will be determined to match with the PDM
Systematic research on project delivery systems started from the latter part of last century, especially when DB became popular again in the construction industry. e related research can be mainly classified into the following categories: performance comparison of different PDMs and PDM selection. is part focuses on related work about the PDM and introduces contract strategy briefly as well
Summary
According to the data released by the National Bureau of Statistics of China, the total output value of the national construction industry in 2017 reached 213954 billion yuan, with a 10.5% year-on-year growth [1]. Considering that the design and construction are two of the most important activities in any project implementation, project delivery systems can be classified into two categories according to whether the design and construction are integrated and achieved by a single contract. As a matter of fact, both research and practice show that one of the key success factors of a construction project is the project execution planning, while the core of this plan is the project delivery method and contract strategy [8]. En in the detailed design, the most proper variant will be selected or a new variant will be designed based on DB or DBB according to the result of the first step, and the contract strategy will be determined to match with the PDM. When selecting DB or DBB in the first stage and determining the variant of them in the detailed design, the value-added analysis of project objectives is conducted to make the decisions
