Sustainable construction indicators : an examination of clients' requirements in tender documents

摘要

Tender documents are instrumental for clients to identify the extent to which contractors can undertake some predefined construction activities. By examining tender documents, this study aims to identify the practices of sustainable construction in China. A review of literatures and tender evaluation systems was conducted firstly to derive a set of sustainability performance indicators of construction process. This step was followed by interviewing professionals for validation, and 497 tender documents were collected from 30 major cities of China. The research findings indicate that whilst clients play a vital important role in formulating the rule of sustainable construction, they pay insufficient attention to both environmental and social sustainability performance. This study provides guidance for tenderers to adopt appropriate bidding strategies and shed some lights on the improvement of sustainability performance from the perspective of clients' demand.
