Although complexity and resilience are key inter-related characteristics of construction projects, little is known on how to monitor these characteristics and their implications for safety management. This study investigates the contribution of Safety Performance Measurement Systems (SPMS) as a means for monitoring and understanding of sources of complexity and resilience in construction. It is based in three empirical studies carried out in construction projects, two in Chile and one in Brazil. Two main tools were applied in these studies: (i) the Technical, Organizational and Environmental (TOE) framework, focused on complexity; and (ii) the Resilience Assessment Grid (RAG), focused on resilience. Improvement opportunities were identified for existing SPMS. Also, a set of guidelines for the design of SPMS emerged from these studies as well as a model that explains the connections between the main constructs encompassed by the guidelines.

监视建设项目的复杂性和弹性：安全绩效评估系统的贡献。

尽管复杂性和弹性是建设项目的关键相互关联的特征，但如何监视这些特征及其对安全管理的影响知之甚少。这项研究调查了安全性能评估系统（SPMS）作为监视和理解建筑复杂性和弹性来源的一种手段。它基于在建筑项目中进行的三项经验研究，其中两项在智利，一项在巴西。在这些研究中使用了两种主要工具：（i）技术，组织和环境（TOE）框架，其重点是复杂性；（ii）弹性评估网格（RAG），重点是弹性。确定了现有SPMS的改进机会。也，
