“…Table 1 shows the most commonly cited criteria dealing with "Contractor selection criteria" or "Contractor pre-qualification criteria". Furthermore, the researchers suggested other criteria, such as risk [19], environment [20,34], equipment resources and current workload [19,21,22,37,38], company characteristics [2] and business ethics [10], legal capacity [7,10,15], warranty [1,10], design [15,18], and firm background innovative capabilities [23].…”

Contractor Selection for Sgraffito Decoration of Cultural Heritage Buildings Using the WASPAS-SVNS Method

2019

Sgraffito is an ancient decorative technique applied in walls, produced by using layers of cement plaster tinted in contrasting colours to a moistened surface. This decoration originated in Italy and has been expanded in different European cities or villages. Nowadays, this decoration technique has almost disappeared because of decomposition, inexperience, or lack of knowledge. The preservation and restoration of the sgraffito technique is the most challenging and vital task of cultural heritage buildings’ preservation. Consequently, the conservation of sgraffito depends not only on the historical and architectural knowledge, studies, and conservation projects of the cultural heritage buildings, but also demands the experience, proper qualification, and knowledge of the contractor. This paper presents six principal criteria. Three possible variants for contractor selection for sgraffito decoration of cultural heritage buildings are proposed, and six principal criteria for their evaluation are suggested. The research employs the Analytic Hierarchy Process (AHP), SWARA (Step-Wise Weights Assessment Ratio Analysis), and WASPAS-SVNS (Weight Aggregated Sum Product Assessment-Single- Valued Neutrosophic Set) methods.

“…Moreover, contractor or subcontractor prequalification and selection have been presented by several researchers, applying Fuzzy Sets (Niento-Morote & Ruz-Vila, 2012; Afshar, Alipouri, Sebt, & Chan, 2017;Alhumaidi, 2015;Nassar & Hosny, 2013;Plebankiewicz, 2012) and Fuzzy Sets approaches combine with MCDM techniques: Fuzzy AHP (Nyongesa, Musumba, & Chileshe, 2017), Fuzzy AHP and Fuzzy TOPSIS (Taylan, Kabli, Porcel, & Herrera-Viedma, 2018;Polat, Eray, & Bingol, 2017;Nasab & Ghamsarian, 2015), Fuzzy Set Theory and EDAS (Keshavarz Ghorabaee, Amiri, Zavadskas, Turskis, & Antuchevičienė, 2018), Fuzzy ELECTRE (Hashemi, Mousavi, Zavadskas, Chalekaee, & Turskis, 2018).…”

The low bid is the most common applicable method in the contractor selection process, considering by only one dominant criterion. However, the lowest price criterion not allows selecting qualified, responsible, sophisticated, and knowledgeable contractor for cultural heritage projects. Moreover, the improper contractor selection may induce claims, litigation, and poor quality work, increased costs for project performance or management. Selection of appropriate contractor is very important for the success and excellent accomplishment of cultural heritage projects. This study presents criteria evaluation for contractor selection in cultural heritage projects. This paper provides reviews of contractor selection and proposed criteria evaluation, and determines the criteria of culture heritage contractor selection. This study applies the multiple criteria approach: AHP, PROMETHEE and EDAS approaches.

Sgraffito is a historical decorative technique applied in walls. This decoration could be seen in different European cities or villages. Nowadays, this decoration technique is almost disappeared because of decomposition, inexperience or lack of knowledge. Moreover, the preservation and restoration of sgrafitto technique is the most challenging and important task of cultural heritage buildings’ preservation. Therefore, the preservation of sgraffito depends not only the historic and architectural knowledge, studies or conservation projects of the cultural heritage buildings, but also demands the experience, proper qualification and knowledge of contractor. This paper presents criteria set for selecting sgraffito techniques’ contractor of heritage buildings. The study determines methods, set of criteria for sgraffito technique’s contractor selection, overview of sets the assessment criteria of selecting contractor. The research applies the Analytic Hierarchy Process method (AHP), seeking to determine the critical criteria and to get the weighting for each criterion.
