    Developing a Framework for Construction Sector Capacity
    (UTS ePRESS, 2022-11-28) Le ATH; Domingo N; Macgregor C; Potangaroa R
    Understanding construction sector capacity allows stakeholders to assess the ability to deliver construction projects critically. However, the capacity concept in the construction sector is dynamic, and interrelationships of capacity at different levels have not been explored thoroughly. Accordingly, this paper reviewed studies on capacity at different levels: sector, organisational, and individual to (1) identify attributes of capacity at each level; (2) map relationships of the capacities in the construction sector; and (3) develop a conceptual framework of project capacity in the construction sector and propose future research directions. This study used an integrative literature review approach to synthesise literature from various domains to describe different levels of the construction sector’s capacity. The findings of the literature review conceptualised a construction sector capacity framework at four levels: sector, organisational, individual, and project. The detailed descriptions of the relevant attributes at each level advance our understanding of capacity within the construction sector and are fundamental to developing capacity assessment tools for the construction sector. The relationships formed in the proposed framework help explain how the capacity at each level affects the system. Findings also serve to identify areas for future research, including investigating interrelationships of attributes in the capacity framework.

    Prioritising optimal underutilised historical buildings for adaptive reuse: a performance-based MCDA framework validation in Auckland, New Zealand

    Purpose: Currently trending as a practical approach to promote urban and seismic resilience, the adaptive reuse of historical buildings relies on expertise from various professional backgrounds ranging from conservation, urban planning, construction management, architecture, engineering to interior design. This paper explores the applicability of a performance-based multiple criteria decision assessment (MCDA) framework to prioritise underutilised historical buildings for adaptive reuse in Auckland, New Zealand while balancing the diverse interest of all relevant stakeholders. Design/methodology/approach: A focus group workshop was conducted for relevant adaptive stakeholders in Auckland, New Zealand, to test the applicability of the performance-based MCDA framework developed by Aigwi et al. (2020) and prioritise four underutilised historical building alternatives for adaptive reuse interventions in Auckland, New Zealand. Findings: Findings from this study revealed the significant potentials of the performance-based MCDA framework, both as an evidence-based measurement tool to prioritise underutilised earthquake-prone historical buildings in Auckland's central business district and as an effective decision-making strategy. Also, the framework allowed the inclusion of diverse stakeholders through the integration of collaborative rationality, ensuring consistency and transparency in the decision-making process. Originality/value: The successful validation of the existing performance-based MCDA framework in Auckland, New Zealand, using multiple historical building alternatives, further strengthens its preceding validation by Aigwi et al. (2019) using only two historical buildings in Whanganui, New Zealand. The findings provide a theoretical platform for urban planning researchers to advance performance-based planning for adaptive reuse to other locations and fields. There are also interesting implications for local councils, heritage agencies, architects, urban planners, policymakers, building owners and developers in Auckland, New Zealand, as a guide to improving their understandings of: (1) the intangible values of optimal historical buildings perceived by the community as worthy of protection through adaptive reuse; and (2) the targeted needs of communities in the new functions of an optimal alternative from a group of representative historical building alternatives.
