The influence of stakeholders’ motivations and barriers on construction material use effectiveness
Despite all the ecological, economic and social benefits of improving Construction Material Effectiveness (CME: using less construction materials in buildings, while maintaining the quality of materials for future recoverability), the market development for CME strategies (reducing material use, intensifying use (shared or multipurpose use), extending use, reusing, and recycling) is still slow. A considerable amount of research has investigated the barriers to stakeholders’ engagement with these measures. These studies mostly speculate barriers that may possibly exist rather than identifying the barriers that stakeholders have actually found detrimental. Studies which have conducted interviews/surveys usually investigate a limited number of CME strategies (usually recycling), among a limited number of stakeholder groups (mostly contractor), in few phases of a building lifetime (usually construction). This thesis juxtaposes different CME strategies among various stakeholder groups and building lifecycle phases. A questionnaire was sent to architects, LEED consultants, structural engineers, general contractors, owner/developers, and building operators of recent LEED NC Gold or Platinum certified projects in Metro Vancouver, BC. The goal was to investigate the influence of respondents’ motivations and barrier on the practice rate of the strategies. This study showed that: • Stakeholders’ attitude about the environmental significance of CME strategies does not necessarily result in the higher practice rate of the strategies. • The amount of effort that is put into implementing CME strategies is related more to motivations (or lack thereof) than to being hindered by barriers. • The CME strategies are generally less considered in the planning and design phase compared to other studied phases. However, the practice rate of the strategies in this phase had a stronger correlation with environmental motivations. • The stakeholders’ limited area and time of control and responsibility is a major reason for their lack of interest in implementing many of CME strategies. The following measures are suggested to motivate stakeholders to consider CME: • Encouraging multi-stakeholder decision making processes which engages stakeholders from up-stream and down-stream phases; • Educating stakeholders about personal benefits and lifecycle environmental benefits of CME; • Sharing the benefits and responsibilities of CME among all the influential stakeholders involved during the life cycle of materials. ; Applied Science, Faculty of ; Architecture and Landscape Architecture (SALA), School of ; Graduate
