Extreme heat, urban flooding, supply chain disruption, and energy instability are some of the ways which climate change is progressively interfering with the completion of architectural building projects. A comprehensive, paradigm for managing climate-related risks within the particular context of architectural project management is noticeably lacking in the literature, despite the growing awareness of these hazards. This study addresses that gap by conceptually developing a Climate-Adaptive Architectural Project Management Framework (CAAPMF) and its accompanying measurement instrument; quantification validation of the framework is planned as a subsequent empirical phase and is not reported here. The study conceptualized six independent constructs, Climate Risk Assessment (CRA), Adaptive Planning and Scheduling (APS), Climate-Responsive Governance (CRG), Stakeholder Climate Engagement (SCE), Digital Climate Management Tools (DCM), and Resource Resilience Capacity (RRC) operating through the mediating construct of Climate Adaptation Capability (CAC). These constructs are based on Climate Resilience Theory, Adaptive Management Theory, Dynamic Capability Theory, and Systems Theory to determine Climate-Resilient Project Performance (CRPP). EFA, CFA, and SEM were used to analyze the measurement tool, which consists of 56 items on a five-point Likert scale covering eight categories. Six mediating routes via CAC were among the 19 hypotheses that were explored. No survey data have been collected to date; thus, this paper reports the conceptual and instrument-development work as complete, and presents as a fully specified, but not-yet-executed, protocol.
