Construction site layout planning practices in inner-city building projects: space requirement variables, classification and relationship

ABSTRACTAn inner-city building construction site for vacant land development or redevelopment of existing property is a site surrounded by buildings, occupants, and busy street(s); its space is the most important but limited resource that needs wisely planned and professionally used. The study aimed to assess the construction site layout planning (CSLP) practice and the classification of space requirement variables for inner-city building sites. Thus, the study adopted a triangulated study approach and the data was collected through a sequential mixed method that includes case studies: semi-structured interviews, document evaluation, and site visits observation followed by a two-round Delphi survey. The study has identified the space requirement variables, classification, and relationship for CSLP of inner-city sites; classified under three categories: Micro-space (four), Macro-space (18), and Paths (five); and have significant to strong associations with each other. The current practice shows the CSLP is overlooked or fragmented which causes a congested site condition. So, the provided insight on the strong relationship between space requirements will be a basis for shifting from the temporary-facility-centered planning methods towards an integrated CSLP approach to overcome contractors’ problems in the continued redevelopment demand of the inner city
