summary:Building construction is a very important development activity of any country. In addition to itsbasic role of providing shelter, the sub-sector contributes significantly to the Gross Domestic Product of bothdeveloping and developed countries, and plays an equally important role in the creation of employment.Unfortunately, the way building projects are managed in developing countries has often led to the under- ornon-exploitation of the potential of these projects. Many factors, including inaccurate estimation techniques,poor and the challenge in predicting building construction labour cost, contribute to the poor management ofbuilding construction projects. Thus labour costing has become a key parameter for use in building constructionprojects. This article aims to investigate the use of an ontology-based technology in modelling information aboutlabour costs in order to facilitate decision-making among building developers. This is achieved by pursuing twoobjectives. Firstly, a domain ontology that captures knowledge about labour costing practices in developingcountries in general and Cameroon in particular is developed. Secondly, an ontology rule-based application isdeveloped to facilitate decision-making and computation of labour cost in building construction projects. Threeexemplary case scenarios are presented to illustrate how a construction decision-maker can intuitively query thelabour cost ontology and navigate the results.
