Description
Building construction is an integral part of national economic development. Nevertheless, it
requires enormous capital to implement sustainable building construction. Construction
activities contribute to environmental degradation and pollution by material extraction and
carbon emissions, amongst other problems. Stakeholders in the industry continue to seek
ways to optimise resources to save costs and protect the environment. Value Engineering
(VE) seeks to strike a balance between costs and functions performed by buildings and
infrastructures without compromise. Therefore, this survey aims to understand how VE
principles can optimise building resources and protect the environment without loss in
quality, performance, and reliability. The assessment reveals that using VE principles
optimises building functions at the lowest overall cost without affecting quality and
performance. The approach addresses the oversizing of structural elements of buildings
and mechanical and electrical systems. It resolves the complexity of building sizes and
shapes via material diversification. It identifies the function of a building before investing to
save costs and avoid project abandonment. The practice has the potential to provide an
environmental advantage through the dematerialisation of the building structures to mitigate
greenhouse gas emissions linked to the built environment occasioned by the energy
released from fossil fuels. The method simplifies multi-objective resource optimisation
associated with supertall building construction. In addition, abandoned projects can be
revived by identifying the status and challenges with the project and suggesting strategies
that facilitate the easy take-off of the rehabilitation of such projects. Furthermore, building
projects can achieve green and sustainable construction by adopting value engineering
strategies.
