“…In this case the Czech Republic is characteristic in that there is almost no usage of design-build in the public sector, even though the private sector is familiar with this scheme. The motivation is to show the advantages of design-build to public authorities (AL-RESHAID 2005).…”

Risk is an omnipresent effect in every area of human activity. Ignoring it can cause serious problems. This article is about eliminating risk in public contracts using the design-build method as a possible solution to reduce risk. First, we need to compare the standard method of design-bid-build with its alternative, design-build. Two methods are used in this article to analyse riskthe main method is RIPRAN. The evaluated results provided by the RIPRAN method are processed by research data using a scoring method with a risk map. The analysis is going to detect the difference between the DBB and DB methods, primarily in appearance and its impact on the realization of the whole construction. The comparison identifies numerous contractual topics and risks included in both and gives deeper insight into risk management, both for the contracting party and also for public procurement. Applying risk analysis strategies and tools to the process will help decision-makers evaluate and select the most suitable delivery method consistently and defensibly. This paper gives generic risk factors related to both project types.Keywords: design-build, RIPRAN, score method with a risk map Risk management methodsIt is very important is to understand the main characteristic of risk management to be able to decrease the risk level.

“…A series of decision models based on various approaches were developed for contractor selection, such as the integrated multi-objective decision making process (Keeney and Raiffa 1976;Kashiwagi and Byfield 2002;Demirtas and Üstün 2008), the neural networks (Khosrowshahi 2001;Lam et al 2000), AHP (Al-Harbi 2001;Al-Reshaid and Kartam 2005;Mahdi et al 2002;Topcu 2004), DEA (Tran 2002;McCabe et al 2005) the multi-attribute analysis model (Lai et al 2004), analytic network process (Cheng and Li 2004;Ravi et al 2005;Bayazit 2006), integer programming (Missbauer and Hauber 2005), unit-price based (Wang et al 2006), multi-attribute utility theory (Lambropoulos 2007), fuzzy-excellent order method (Wang and Triantaphyllou 2008), fuzzy-AHP-Smart (Padhi and Mohapatra 2009), and the binary goal programming model (Padhi et al 2010). Although these methods were designed to single decision maker, they have drawn great attention to the area of contractor selection in construction projects and provided basis and new ideas to group decision-making.…”

A Group Decision-Making Aggregation Model for Contractor Selection in Large Scale Construction Projects Based on Two-Stage Partial Least Squares (PLS) Path Modeling

Modern projects are normally characterized by huge investments, long construction periods, and complex technology. Therefore, the selection of an appropriate contractor for smooth project delivery is challenging. Previous studies attempted to develop suitable frameworks for contractor selection. However, correlation among indicators, the subjectivity of indicator weights, and heterogeneity among experts' professional capabilities for selecting contractors were not successfully removed from the decision-making process. Typical partial least square (PLS) path modeling can solve these problems. However, it can only solve problems with the same direction correlation among the indicators (e.g., the correlation coefficients of the indicators are all 123 B. Liu et al. positive). For indicators with different direction correlations, path modeling is helpless. Aiming to overcome this limitation, this research introduces a group decision model based on two-stage PLSs path modeling. This decision model can eliminate correlation among indicators and the impact of subjectivity and heterogeneity among experts on the reliability of weighting schemes; more importantly, it can effectively solve the problem of having correlation indicators with different directions. Through a literature review, we first established an indicator system of contractor selection on large scale construction projects. Second, a two-stage PLS path modeling combined with the maximization of deviations principle was proposed as an aggregation approach for performance evaluation. Finally, a comparison was made between the two-stage and typical PLS path modeling methods through a case study, which was conducted to validate the reliability of the new approach.

“…One focuses on contractor prequalification or contractor selection from the owner's perspective [20][21][22][23]. The other emphasises on analysing factors determining the degree of subcontracting [24] or supporting management in subcontracting rating from the contractor's perspective [25].…”
