Impact of qualifications-based selection of engineering services on project outcomes**

随着政府机构服务外包的扩大，专业建筑和工程（A/E）服务的采购在加拿大各地不断增加。为了保持公平和透明，公共机构在进行机电服务招标时通常采用基于价格的采购流程。但是，工程咨询顾问的业绩已显示影响到所建设施的质量和费用。尽管A/E服务的绩效可以影响项目交付，但影响项目结果的资质类型，以及它们影响绩效的程度，在建筑工程和管理文献中仍然是一个相对未被探索的方面。将这些知识封装到一个可执行的决策支持系统中，将使采购方能够为其特定项目选择最佳的服务提供商，确保在加拿大建造的设施更高效、更有创意、更方便使用、更可持续和更安全。采用基于资质的选择方法预计会降低建筑成本，这将使政府机构能够为更多的项目提供资金，进一步加强向公众提供的服务，同时增加公众的信心，即纳税人的资金被分配给了为加拿大人提供最物有所值的建筑/工程公司。****建议研究的目标是定义、评估和预测A/E资格对加拿大项目成果的影响，并将这些知识概括为行业的决策支持工具。将确定影响A/E绩效的资质，将量化这些因素对历史项目结果的影响，并将开发能够预测各种A/E资质对未来项目结果影响的模拟模型。总之，拟议的研究旨在开发一种基于资格的选择程序，以决策支持工具的形式，各种组织可以在采购决策期间公平透明地考虑a /E服务的质量和投标价格。****

As outsourcing of services by governmental organizations expands, procurement of professional Architectural and Engineering (A/E) services is increasing across Canada. In an effort to maintain fairness and transparency, public organizations often use a price-based procurement process when awarding bids for A/E services. Performance of A/E consultants, however, has been shown to influence the quality and cost of built facilities. Although the performance of A/E services can impact project delivery, the types of qualifications that affect project outcomes, as well as the magnitude by which they affect performance, remains a relatively unexplored aspect of construction engineering and management literature. Encapsulating such knowledge into an implementable decision-support system would allow procurers to select the optimum service providers for their particular project, ensuring that facilities built in Canada are more efficient, creative, user-friendly, sustainable, and safe. Reductions in construction costs expected to arise from adopting a qualifications-based selection approach would allow government agencies to fund additional projects, further enhancing the services provided to the public while increasing the public's confidence that taxpayer funds are being allocated to A/E firms that are providing Canadians with the best value for their money. ****The goal of the proposed research is to define, assess, and predict the impact of A/E qualifications on project outcomes in Canada and to encapsulate this knowledge as a decision-support tool for industry. Qualifications impacting A/E performance will be identified, the impact of these factors on historical project outcomes will be quantified, and a simulation model capable of predicting the impact of various A/E qualifications on future project outcomes will be developed. Altogether, the proposed research aims to develop a qualification-based selection procedure, in the form of a decision-support tool, which can be used by various organizations to fairly and transparently consider the quality of A/E services along with bid price during procurement decisions.****
