Parameters for building materials specifications in Lagos, Nigeria

Abstract

The responsibility of specifying materials for building construction purposes within Nigeria rests on the architects. Understanding the appropriate parameters for specifying building materials that could lead to immense financial proportion is required from the architects. The level of understanding and knowledge of architects is germane to the optimum performance of buildings throughout their life cycle. The methodology applied for this research involved the administration of a structured questionnaire on professional architects within the study area to determine the basis of their decision on the materials they specify or chose for building finishes. The parameters used to measure the specification of materials for finishes are client's choice, cost, climatic compliance, and maintenance demand of materials. Findings show that the maintenance demand of materials is the most important factor that determines the specification of materials irrespective of the choice of client and climate. However, cost occupies a prominent role in the decision process. It also shows that most architects are not fully aware about the role of climate in determining the life cycle of materials in tropical environments. The compliance of materials to ever-changing climate does not constitute a major factor in the specification of materials in the area.
