Framework for Designing Project Delivery and Contract Strategy in Chinese Construction Industry Based on Value-Added Analysis

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

Measuring the Value of Farmland-Elevating Engineering in the Reservoir Area of a Key Water Conservancy Project in China

With the development and construction of key water conservancy projects, many problems such as population migration in reservoir areas have become increasingly grave in China. The implementation of farmland-elevating engineering has become an effective way to reduce the loss of cultivated land, prevent soil erosion, and ensure food security and social stability. On the basis of the key technical analysis of farmland-elevating engineering, this paper constructed a value system of farmland-elevating engineering from aspects of social value, ecological value, and economic value and established corresponding measurement models, respectively. Taking a key water conservancy project in Jiangxi province as an example, this paper measures the value of farmland-elevating engineering implemented in this project. The results show that the implementation of farmland-elevating engineering can produce great value. This study aims to provide reliable references for the decision-making regarding farmland-elevating engineering
