A case study approach outlining factors for alternative use in wall construction for block work and precast twin wall systems

Abstract

From basic definition, a wall is a continuous vertical structure which surrounds or divides an area of land while providing a defensive or preventive barrier. Moreover it may be either a structural or non-load bearing one. Hence, the construction industry adopts various techniques to bring about the required structure. In this dissertation, the researcher explores factors for alternate use in wall construction. The aim is to understand key challenges which arise when implementing such alternative construction methods. Block work and twin-wall construction are two methods used locally each facilitating the industry through specific techniques. Additionally, the issues that could impede or upkeep the use of new technologies are identified.
