Its preservation requires consideration, liability, know-how, know-why and experienced employee. Cultural heritage buildings’ performance is complicated work, therefore selecting a contractor for heritage buildings’ protection and restoration is a difficult assignment. The improper contractor's choice could activate cost overruns, lag, conflicts, declines, imperfect performance or added expenditure for project administration and accomplishment. This paper submits the quantitative and qualitative criteria setting for selecting heritage's contractor. The Analytic Hierarchy Process technique is applied to decide important criteria and to get the weighting for each criterion. The PROMETHEE (Preference Ranking Organisation Method for Enrichment Evaluation) technique is applied for the selection of the most efficient cultural heritage contractor's alternative.
