This paper describes the work to be done by the FUNSIEC project, which aims to evaluate the feasibility of building an Open Semantic Infrastructure for the European Construction Sector (OSIECS). Such an infrastructure is to be built by selecting semantic resources devoted to construction in different languages, exploiting some public results produced by international initiatives (e.g. IFC) and European funded projects. OSIECS will be open to any linguistic resources; in particular those developed for less widely spoken languages and those of the Candidates countries. The innovation in OSIECS is to be on the semantic mappings to be established among the existing semantic resources. The assessment of the results produced by FUNSIEC is centred on the main subjects: its business plan and the education (in the large sense) of the practitioners from Construction regarding the use of semantic resources.
