Abstract



Private or individual building developers ignorantly or deliberately have been the source of violation of building safety or stability standards/codes in Nigeria. This has resulted into serious consequences including high rate of structural collapses, project abandonment, etc. To guide such developers and various building consultants alike in planning, designing and execution of building projects, this paper used twenty-four of the well documented (designed and quantified by qualified specialists) buildings constructed in and around Port Harcourt over the last two decades to derive useful cost-based indices. These indices could also be used to match available fund with project scope and achievable phase or stage. One of these indices, the german floor cost index (gfi) when combined with prevailing (current) costs of concreting materials (cement, sand, gravel, water) and labour could predict fairly accurately the actual building costs. Also as multiples of gfi, substructure cost index, sci and roofing cost index, rci could predict componental costs of substructure and roofing for phased development purposes.
