Abstract. In project development it is hardly possible to get exhaustive and accurate information. As a result, the situations occur, the consequences of which can be very damaging to the project. Inaccurate evaluation of the strategy related to capital investment and project implementation is one of the reasons why such estimates are not required in practice. Instead, a classification approaches may be used for this purpose. The decision-making process, based on the established risk assessment principles expressed in linguistic terms, requires qualitative judgement and experiential knowledge of the construction experts. Presented structured and realistic methods deals systematically with different risk management situations and assist the investors in reaching the correct risk assessment of possible alternatives will be of great value. This paper presents a methods of multiattribute comparativite analysis (CLARA and SAW methods) of variants of investment classified risks in construction. A practical case to illustrate how the methods works is presented.
Some methods allowing for the selection of the most suitable contractor based on 26 criteria are offered. The bidding procedures of FIDIC, the international organization of consulting engineers are assessed. Contractors are evaluated by a multicriteria decision method COPRAS. The significance of the contractor evaluation criteria is determined by ranking. A description of the criteria and their rankings according to 100‐point scale are provided. A case study of selecting the contractor for the construction of a trade and entertainment centre out often bidders is also described.
The successful performance of construction enterprises as well as their competitiveness are largely determined by the construction technology and management methods used. In this respect two levels referring to a building or structure itself and to a construction enterprise as a whole should be distinguished. The technology of a building or structure embraces its construction system generally characterizing building materials, design solutions and load‐bearing structures and enclosures used in the construction of this particular building. The problem of selecting a general technological criterion for the whole construction enterprise arises.
A construction enterprise fulfilling its annual program can simultaneously construct buildings and structures based on various construction systems, i.e. it can use various technologies. Searching for an integrated criterion to describe an enterprise as a whole three main issues including the variation of the applied technologies and their volumes and technological effectiveness should be taken into consideration.
In the paper the problem of determining technological effectiveness of construction systems is considered. A method of pairwise comparison developed by T. Saaty was used to address this problem. The calculations were made for all thirteen technologies currently used in Lithuanian construction industry. Based on the suggested approach the weight of technological effectiveness was determined for each of them in the parts of one.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
