Selecting and Evaluating Suppliers in the Czech Construction Sector

Abstract

Selecting a capable contractor is one of the crucial prerequisites for the successful completion of a construction project. This paper addresses the issue of selecting and measuring the performance of suppliers. Using a web-based questionnaire survey, quantitative data was collected from Czech construction companies that act as main contractors and subcontractors within the supply chain.The data was evaluated by applying absolute and relative frequency, the relative importance index and the chi-square test of independence. The findings revealed several managerial implications for purchasing professionals in both areas. The findings were of interest with regard to the significance of individual selection criteria in the selection of suppliers. Data was analysed on both the usage of performance measurement systems and the frequency of performance measurement. We concluded that somewhat large differences exist between main contractors and subcontractors in terms of the use of selection criteria and that performance measurement is not universally applied in the Czech construction sector.

Pythagorean Fuzzy AHP Based Dynamic Subcontractor Management Framework

“…Although cost, time, and quality are observed as priority targets in the literature, it is expressed that there is a need for other headings in different dimensions (such as adequacy, compatibility, environment and OHS) in the developing construction industry. These criteria have been presented in the literature by researchers [8,30,[38][39][40] for different purposes. Within this background, determined SC-PMC were grouped under seven main topics that are Time, Cost, Quality, Resource Adequacy, Compatibility and Communication, OHS-Environmental Protection and Leadership, respectively.…”

“…Ng [24] conducted a study with the criteria of, 'completion of job within the time' and 'adherence to program' sub-criteria. Hanák and Nekardová [40] created the SC selection criteria, and it is seen that these criteria are also important for performance measurement. The criterion related to time is 'meeting the delivery deadlines' and 'speed in remedying claim of defects'.…”

“…El-Mashaleh [44] mentioned the importance of cost control by making timely payments with the criterion of 'prompt payment to labor'. Hanák and Nekardová [40] included 'meeting the planned price' criterion related to cost dimension in their studies.…”

“…How SCs will respond to this has also become an important question. Based on this, Hanak and Nekardova [40] mentioned the 'ability to flexibility respond to changes in the project' criterion in their work.…”

A Multi-Criteria Decision Support Concept for Selecting the Optimal Contractor

“…Therefore, such requirements can be achieved be establishing adequate selection criteria during the procurement process. This has been done by all the previously mentioned researchers, but some focused on defining the main criteria in a more detail way [3,13,[48][49][50][51][52][53][54] by using them to select tenderers in competitive tendering systems.…”
