The cross-sea bridge construction environment is poor, and its construction technology is complex. To determine the general contract management idea, realize the overall operation goal, achieve the standardized management and maximized and optimized benefits of the engineering project, it is of great practical significance to discuss the management of the cross-sea bridge construction contract. The construction enterprises should pay attention to the management of construction contract, which is as the basis of arranging for construction, pursuing for claim, controlling engineering cost and settlement and providing possibilities for risk transfer, carry through the real-time institution development and establish the contract management system, so as to control the business cost and drop the business risk. Incorporated with the actual situation of the construction contract signing, the issues and improvement measures in the signing and management of the cross-sea bridge construction contract are given.

The article is devoted to the analysis of means of formation of information and communication systems taking into account inclusive design. The constant development of innovative project developments in this direction indicates a change in conceptual approaches to their design and the urgency of changing the paradigm of inclusive education, which takes into account accessibility and safety for all students without exception. The system approach allowed to establish connections between the ergonomic component of the formation of the design of information and communication systems, their functionality and aesthetic expressiveness. The method of abstraction helped separate from certain properties and relations of the object and at the same time focus on those properties that are the direct object of scientific research; the method of generalization contributed to the logical completion of abstraction; the method of classification allowed to determine the specific characteristics in solving the problems of the best examples of project activities with the possibility of their theoretical justification. The social significance and relevance of the chosen research topic lies in the analysis and identification of fundamentally new design solutions for the educational space of secondary schools, which have been implemented in foreign countries. Characteristic features of their solution are taking into account the principles of universal (inclusive) design based on the use of technological innovations, availability of spatial planning, design and artistic solutions, which significantly improve the implementation of information and communication systems. Functional comfort, in this case, is considered as a generalized criterion for optimizing the system "human-object or process-environment". In addition, the inclusive approach takes into account the comfortable and aesthetic conditions of students' adaptation to the new modern standards of education and testifies to its practical significance. It is a special synthesis of ergonomics and design in the educational environment, and also allows you to create new "scenarios" of educational activities of modern students. Analysis of aspects of the developed design model of an inclusive approach in solving information and communication systems will help initiate its implementation in the educational space of secondary schools of Ukraine.

Abstract: China’s high-speed railway network has already achieved speeds of 350 km/h; however, this could be further increased to 400 km/h. After considering the development status and technical level of the high-speed railway system in China, this study indicates that there are four key technologies involved in improving its operational speed: the track, the electrical moving unit, the control system and the traction power supply. Through an experimental analysis, an evaluation index for the high-speed railway is then constructed based on four aspects: safety, comfort, intelligence and environmental protection. Using this system, the rationality of the high-speed railway speed-improvement plan can be scientifically evaluated. The results are of practical significance to the Chinese railway administration, as they can be used to formulate specific plans to increase rail speeds, and therefore promote the rapid development of the high-speed railway network in China.

The cave dwelling, as one of the most typical and traditional characteristic local housing styles in the loess area of Northwest China, has been adopted widely in many areas since ancient times. The construction of the cave dwellings supports environmental protection, makes use of innovative construction technology, and preserves historical cultural heritage. The cave dwellings have practical significance and play an important role in the current society. Although there are many natural advantages to use cave dwellings, they also pose many problems, such as high moisture, inadequate lighting, poor ventilation, insufficient strength, and so on. The most serious problem is related to moisture, which affects the comfort, security, and safety of the residents; it needs to be addressed. The authors propose to resolve this problem by developing a method of building a damp-proof course in the bottom of these cave dwellings. Meanwhile, specified experiments were carried out to validate the feasibility of this method. The results show that the method is reasonable and practical, and it can be implemented easily and conveniently in the future. This research has significant practical value; the results can improve people’s living environment and increase comfort and safety of cave dwelling.

At the very moment various construction and projection firms offer to use all kinds of new technologies and its systems, structural decisions, proper materials used as well as work implementation methods, without paying any attention to the factors, effecting the choice of selecting the most effective technology of construction process. Having in mind that funds should be realized rationally, it is the matter of vital importance to measure the practical adaptability of technologies being used either they are new or have been used for many years to achieve the best technological decisions. In order to achieve the efficiency of the funds invested and diminishing construction duration as well as increasing its quality, various construction process technologies are developed and improved by using modern technical and informational tools, which are integrated into the stages of projection and construction. The paper analyzes the methods of multi-criteria alternative technological solution evaluation in construction environment. Methodology, which is used, allows to complex evaluate the efficiency of construction designed decisions at the stage of preparation phase. There has been done a practical technological modeling of installation process of concrete floor as well as there have been determined optimal solutions. In order to achieve the results mentioned, a method of proximity to an ideal point was used.

The need for modernization of curricula is growing with the development of new technologies to support teaching, changes in business strategy of universities in Poland and European Union, and development of the society. In response to these changes, at the Department of Civil and Environmental Engineering at Poznan University of Technology, new English-language specialty master studies - Construction Technology Management was launched in March 2014. Studies are based on the cooperation between the student, the industry and the university, allowing students to get to know the specifics of the construction industry. In addition, Poznan University of Technology is involved in an MBAIC project MBA in construction aimed at common study for postgraduates. The synergy achieved through the implementation of these two projects enables the possibility to educate construction managers capable of communication in English, possessing knowledge regarding innovation in the construction industry, who are well prepared to enter the labour market and have the possibility of subsequent improvement of managerial competences.
