Abstract: Construction is among the top priorities in the economy; it has direct impact on the population’s standard of life. Trends in construction resent some key indexes to evaluate the level of economic and social development of a country. During the latest decades, the above-mentioned notions have brought forward the cluster policy, which can dramatically influence the competitive strength of both the construction business and of the national economy as a whole. The particular feature of cluster policy is that it unites the economic and social policy of the State with management of business entities. The purpose of the present article is as follows: basing on the analysis of the performance of construction clusters of various countries in Europe, highlight their common and specific features and propose directions for further development. The tasks of the present investigation are: firstly, identify specific features of establishing and developing construction clusters; secondly, define the basic features of European construction clusters, thirdly, identify common and specific features of construction clusters in various countries of Europe, fourthly, propose courses of action to promote the cluster policy in regard to the sphere of construction.

Abstract: Successful development of a construction company under the market economical conditions depends on the number of contracts for construction works awarded to the company, usually on the competitive basis. The winner of a tender is chosen from the participants that have previously proved their qualification at the prequalification stage, on the basis of two criteria: bid price and construction period. Bid price is the key factor which is of the most importance to the client. It is based on contractor’s estimation of construction cost. The most common construction cost assessment methods use the valid estimate norms calculated on the basis of the averaged work costs which do not consider fluctuation of actual market prices for different kinds of resources and the chosen methods and technologies of facility construction. This paper aims to provide the basis for the development of accurate cost assessment method which is based on the actual market prices for all kinds of resources and on the methods and technologies of facility construction chosen be the contractor, rather than on the valid estimate norms. The main task therefore is the development of the key principles and sequence of construction cost assessment during preparation for tender. The offered assessment method is based on construction schedule illustrating the time association of all construction processes and is the basis for determination of the actual volume of the required resources and funds at each time point of facility construction. Given the many-sidedness of the arising problems, construction cost assessment should be conducted based on the following principles: construction schedule optimization; accounting of market cost of resources; generating the best plan of construction resource provision; cost minimization and financial flow optimization; risk accounting; project approach. Using these principles during assessment of facility construction cost within the framework of bid preparation allows increasing its competitive ability according to the main winner choice criteria – construction cost and periods.

Abstract: Lower levels of profitability in the production process and reduced demand have made it necessary for enterprises to diversify their activities and to extend the scope of their interests. In this article there is examined a model for evaluating the effectiveness of separate types of production activity insofar as they are the most preferable for enterprises in the construction sector. Also, there are presented experimental calculations and analyzed results for choices in the directions of diversifications.

Abstract: Today is already on the market, ample-effective tool for the fulfillment the working principle of BIM (Building Information Model). This method is above all the desire for collaboration, sharing information within a specific project. Cooperation but requires certain rules. They guarantee us success in communication between participants.The paper demonstrates how it can streamline the work in BIM. The introduction of new functions in design teams. A new procedure for working in BIM

Abstract: In the process of managing water proportions Lake Sevan has its specific place and role, which is the largest natural reservoir of the country and the national wealth. A number of programs and activities were made to preserve Lake Sevan and use the water resources effectively in the past, which are not complete yet. That’s why comprehensive attention should be paid to the preservation of the lake, efficient use of its water resources and environmental problems.

Abstract: Issues of establishing new methodology for urban strategy of the Republic of Armenia are considered. Тhe peculiarities of urban policy at different stages of economic growth of the country are studied. Analysis of underlying legislative, normative and project documents of the post-Soviet period are carried out, particularly territorial planning projects of the Republic of Armenia and separate regions, recently approved master plans and zoning projects of the majority of RA cities. Based on studies formerly undertaken by local scientific subdivisions on development of theoretical basis and prospects for growth of architectural, town planning and building complexes, systems of Urban Code and Urban Cadastre as well have established legislative and normative background, and within the structure of architectural and building complexes а qualitative leap has occured. However, all these developments and urban documents as products of transition period are based on relatively incomplete taxon data. It is obvious that the role of state control and programs formulating single state urban development strategy will increase and remain significant. Division of urban planning activities into separate categories is given that is considered both in an alternative and complex aspect, in the light of basic goals implementation of prospective urban policy and internationally enshrined principles of sustainable development are proposed.

Abstract: For evaluation of technical condition of the buildings their constructions, you can use the methods of risk analysis. These methods may be used for pricing building and construction, depending on their condition, age and use During the subsequent design of the reconstruction or rehabilitation must always consider the scope and extent of the selected type of reconstruction in relation to the potential of harm (physical and financial). In the paper is applied to building assessment the method of universal matrix of risk analysis (UMRA).

Abstract: Selection of equipment for construction projects is a complex process which is a key factor in the success of the project. The purpose of equipment selection is in the most cases to select optimum equipment in terms of optimal criteria which are often in contradiction. This contribution is focused on application of some multi-criteria methods for solving multi-criteria optimization problems in the area of earthwork processes because the choice of these methods is almost difficult. These techniques have been implemented in an earthwork process and selected equipment which are available on the market by company Caterpillar. In this contribution are presented the key mathematical models for these methods, which have been created as a tool for comparison of selected equipment.

Abstract: The objective of any construction work is defined as the optimal use of resources, it is focused on building efficiency, so as to ensure quality in reaching the minimum construction costs and ensure environmental protection, safety at work. The building production is affected by many factors. With some we can count, but we cannot predict some for certain in advance. The essential precondition for successful implementation of a construction is thorough and timely preparation of pre-production and production engineering (technology designing), which provides for the effective implementation of the works.

Abstract: Magna Charta Universitatum in Bologna began the process of harmonisation among European universities, called Bologna Process, as early as January 1988. This process has been influencing also the education at the Faculty of Civil Engineering of VŠB – Technical University of Ostrava (FAST, VŠB – TU Ostrava).This paper is focused on the pedagogical activities pursued at FAST, VŠB – TU Ostrava from the very beginning, describing the evolution in the range of the study programmes and fields of study offered to students.
