    ENGLISH ABSTRACT: While sustainable construction has gained increasing attention internationally, there are still only limited studies thataddress the issue of sustainable construction in South Africa. Furthermore, the adoption and implementation of sustainable solutions in the South African construction industry is not apparent. The objective of this research study isto understand the current behaviour of construction industry stakeholders with respect to sustainable construction practices and to identifyand examinethebarriers and drivers of sustainable construction in the context of South Africa. This isachieved by adopting a theoretical behaviour change approach to develop an intervention strategy for improvingand facilitatingthe shift towards adopting sustainableconstruction practices and principles,thereby reducingthe negative impact of the development of the construction industry on the environment. Athree-phased, explanatory sequential mixed methods research design approach,guided by the Behaviour ChangeWheel(BCW),was adopted in this study. In Phase Oneof the three-phaseprocess to intervention design, an integrative reviewwas conducted,and a descriptive and content analysis of the barriers and drivers of sustainable construction is presented.A total of 37 articles werereviewed, identifying 56 barriers and drivers from the integrative review,and coded against the Capability, Opportunity, Motivation –Behaviour (COM-B) model components andtheTheoretical Domains Framework (TDF)domains. The barriers and drivers include: capability (knowledge, cognitive and interpersonal skills, behavioural regulation); opportunity (environmental context andresources); motivation (reinforcement, social/ professional role and identity, beliefs about consequences). This provided a theoretical basis for developinga survey questionnaire in phase two of theintervention design. Phase Twoincludeda statistical analysis of the relevant barriers to and drivers of sustainable construction that emergedthrough a survey questionnaire distributed to construction industry stakeholders. Phase Three presentsthe three stages of the BCW design and the development of the intervention components for the intervention toolbox.Five intervention functions and 12 behaviour change techniques (BCTs)wereidentified as relevant to include in the intervention toolbox design to improve the engagement of sustainable construction amongst construction industry stakeholders.Semi-structured interviews wereconducted with subject matter expertsinthe construction industry in order to evaluatethe findings from Phase One and Phase Two, assess the intervention content identifiedwhich consists of the intervention functionsand theBCTs,evaluate the intervention componentsand discuss the quality and applicability of the behaviour change interventiontoolbox.This research study provides an understanding and overviewof the use of the BCWto develop abehaviour changeintervention toolboxaimed at facilitating the adoption and implementation of sustainable construction practices amongst construction industry stakeholders. The BCW presentsa useful framework and systematic approach to integrate multiple sources of data to inform the selection of a theory-based behaviour change intervention strategy.Construction industry stakeholders mayuse thesestrategies to design, implement and evaluate sustainable construction interventions that are feasible within the context of the built environmentin South Africa.
