Abstract

Reconstruction following climate change induced disasters is often required after possible destruction of the built heritage. Achieving greater disaster resilience and reducing disaster risk due to climate change requires that such reconstruction must be balanced with financial and technical feasibility while conserving the historic character of the heritage building. The ‘Build-Back-Better’ mantra is mostly embraced during disaster induced reconstruction, and seeks to build safer and more resilient structures, to reduce pre-disaster vulnerabilities. The ‘Build-Back-Better’ approach assumes that there were vulnerabilities within the pre-disaster built environments that need to be rectified during reconstruction to enhance resilience. As such, achieving building conservation and climate adaptation during reconstruction might at first glance appear completely divergent. Conservation mostly focuses on maintaining the fabric of a place in its existing state, while adaptation may require updating/altering the components of an existing building. However, a more thorough understanding may lead to the conclusion that there is a convergence. This is because the conservation of the built heritage should contribute to resilience, in many ways similar to adaptation, especially in the context of post-disaster recovery. A divergence will result in a fairly unprecedented exposure to natural hazards triggered by climate change, and amplify the performance deficiencies, in terms of functional, technological and normative obsolescence. A convergence is needed due to the increasing requirements of safety, well-being and accessibility of the historic and architectural values, whose conservation is sought. Flooding is the most widely spread climate change induced disaster that affects the built environment globally. This study highlights how heritage conservation can techno-economically align with the resilience agenda, during reconstruction following flood disasters induced by climate change.

Abstract

This study examines the essential financial oversight cost engineering functions performed in the procurement of sustainable infrastructure. This is against the backdrop of the Nigerian construction industry, which has undergone significant transformation through targeted government policies and reforms, aimed at addressing procurement gaps and enhancing infrastructure development. As a result, innovative procurement methods have been adopted to ensure sustainability in public infrastructure projects. Cost engineering and financial management functions are necessary to ensure fiscal accountability in public project procurement. A systematic review of the extant literature is carried out to x-ray cost engineering roles in sustainable infrastructure procurement. Findings indicate a shift from a predominantly public sector-led approach to one driven by private investment, presenting new opportunities for cost engineering roles. Cost engineering expertise is needed in contract administration, risk mitigation, and financial planning and is instrumental in optimizing Public-Private Partnership (PPP) agreements and ensuring long-term project viability. The study underscores the need for Quantity Surveyors, who are professionally skilled in carrying out cost engineering functions, to strategically position themselves within the evolving procurement landscape to leverage emerging opportunities. This study therefore underscores the importance of diversification, and adaptability in navigating industry shifts in the cost management of public infrastructure projects. By embracing these principles, cost engineering roles will maintain relevance in sustainable infrastructure development. There is thus a need to strengthen the connection between government policies, innovative procurement methods, with a view to catalyse cost engineering functions, and their impact in sustainable infrastructure development.
