Sustainable development of any country to some extent depends on successful accomplishment of construction projects, particularly infrastructures. Contractors have a key role in the success of these projects. Hence, the selection of a competent contractor as a complicated and hard decision process has a vital importance in the destiny of any construction project. Contractor selection is in essence a multicriteria decision-making that ought to encompass so many aspects of the project and the client’s requirements on one hand and the capabilities and past records of the contractors on the other hand. Failure in selecting a competent contractor may cause time and cost overruns; quality shortcomings; increasing in claims, disputes and change orders; and even failure of the project. In spite of deficiencies of selecting a contractor by the rule of “the lowest bid price”, it still prevails in many countries including Iran. In this paper, a new contractor selection model based on the best-worst method (BWM) and well-known Fuzzy-VIKOR techniques is proposed as a solution to overcome the deficiencies of the traditional “lowest bid price” rule. An illustrative example of a water channel construction project verified the applicability of the proposed model in practice.

The selection of a suitable contractor for a construction project is one of the most important decisions a client can make for the development of the project. Prequalification is a procedure to examine and gauge the competency and skills of contractors to successfully complete a project if it is given to them. However, the evaluation employed for some prequalification is still ambiguous or highly subjective. This study aims to investigate the shortcoming of the current prequalification evaluation for contractor selection. The methodology of the study is based on a comprehensive literature review and expert survey whereby the criticality of data, obtained from the literature was analysed using expert in the field. Among the prequalification criteria, the current evaluation that employed for management capability is highly ambiguous. Two important shortcomings of current prequalification models regarding the evaluation of management capability were identified. First, the models are not comprehensive since all the variables related to the management capability are not included. Secondly, the models focused almost exclusively on time and cost performance as outcome variables, which may not be enough to evaluate the management capability of contractors. Better evaluation methods have to be developed to assess the management capability prequalification as it has a major impact on time and cost performance of contractors. Therefor future study must be conducted to develop a model that evaluates the management capability of contractors based on the relative variables for the purpose of improving current prequalification selection.

Purpose – This paper aims to present the outcome of a study conducted on the impact that cost-based contractor selection (CBCS) might have on construction project performance. Several criteria are normally used to select construction contractors, competitiveness of the quoted prices of the prospective contractors is one such important criterion. However, choosing contractors solely on the basis of the quoted price may cause poor performance in the construction project. Design/methodology/approach – A quantitative approach was adopted. A critical review of the literature was conducted to develop 50 survey questions relating to the problems that CBCS might have on construction project performance. Findings – Analysis of close data obtained from the survey of construction experts showed the nature of project performance problems associated with the CBCS to be project time delays and non-compliance with construction standards. The major reason they occurred was found to be the reduced profit margin for contractors. Research limitations/implications – The research sample size is small and restricted to construction professionals in Brunei. Practical implications – The study findings present updated information to construction professionals about the inherent impacts of choosing contractors based on cost. Furthermore, this study enhances the approach of selecting contractors within the construction industry. Originality/value – The study made strong and unique arguments about the problems associated with choosing construction contractors based on cost. This study contributes to the body of knowledge relevant to the management of construction projects.

A competent construction contractor is one of the indispensable conditions of a proper process and completion of a construction project. The article presents analysis results of the main criteria considered by Polish public clients in contractor competence evaluation. Research was carried out on the basis of demands stated by clients in restricted tenders announced in 2007. The author also presents research results of the methods and criteria for construction contractor selection, used by Polish private clients. To carry out the research a questionnaire was sent to 27 private clients at the turn of 2006/2007. The results of the research show that public clients in most of the restricted tenders use just one of the criteria used to qualify a candidate to the second stage of tender procedure and it is usually the contractor's experience. Generally, it is characterised by the number of realised projects similar to the ordered one. For private clients, in contractor competence evaluation, technical possibilities of a contractor are especially valued. Experience in similar investments realisation, their quality, the equipment owned, and the staff are the top qualities in the rankings. Appreciated, although to a smaller extent, is also financial reliability of a contractor. Yet, criteria connected with project management are those which are the least valued ones. Santrauka Statybos rangovo kompetencija - viena iš privalomu salygu tinkamai vykdyti statybos projekta ir užtikrinti, kad jis bus užbaigtas. Straipsnyje pristatyta Lenkijos viešojo sektoriaus klientu nustatytu svarbiausiu rodikliu rangovo kompetencijos vertinimo analize. Tyrimo metu buvo remtasi klientu reikalavimais, nustatytais uždaru konkursu, vykusiu 2007 m., metu. Autore taip pat pristato Lenkijos viešojo sektoriaus taikomu metodu ir rodikliu statybos rangovu atrankai tyrimu rezultatus. Tyrimo metu klausimynas buvo išsiustas 27 klientams. Tyrimu rezultatai parode, kad viešojo sektoriaus užsakovai daugumoje uždaru konkursu pirmame etape kandidatui vertinti naudoja tik viena rodikli ir tai dažniausia yra rangovo patirtis. Bendruoju atveju vertinama pagal igyvendintu projektu, panašiu i konkursini, skaičiu. Privačiame sektoriuje vertinant rangovo kompetencija ypatingas demesys kreipiamas i technines rangovo galimybes. Panašiu investiciniu projektu vykdymo patirtis, darbu kokybe, turima iranga ir personalas yra pagrindiniai atrankos rodikliai. Finansinis rangovo patikimumas vertinamas, bet rečiau. Rodikliai, susije su projektu valdymu, vertinami labai retai.
