The article deals with a new product in the Czech market that is quickly getting to awareness of potential clients and gaining a significant place in the local real-estate market. Until recently, the inspection of immovable properties was an unknown concept. Nevertheless, in recent two years such assistance service is being more and more popular. Pertinent specialised inspection companies assist the real property buyer in eliminating potential risks that are related to selection and purchase of a given building. A competent certified inspector checks up to about 200 items of the building and compiles an expert report to help the client to correctly decide whether he should buy the given building or not. The inspector will acquaint the client with a real purchase price, precisely describe all the defects and how to correct them, and finally, he will hand over to the client a complete budget to cover the cost of necessary repairs.
In 2013 the inspection of real properties comes to one of the fastest growing segments of Czech economy. The people intending to buy any real property are more cautious and, now at the time of an economic uncertainty, they begin using the above relatively new assistance service in a large extent.

Integral parts of present-day constructions are various types of wooden roof structures. This contribution documents a diagnostic survey, whose objective was to find the cause of significant acoustic phenomena in a recently completed wooden roof of a family house.

Moisture in moist buildings can be limited by the most different methods. Problems are divided into two papers. The author of paper analyses the conditions of moisture-spread in building in the first part of paper and he solves the selection of sanitation method with less frequent technology of realization. The concrete cause with utilization of air – insulation system then will present in the second part.

The paper contains basic information on the relationship between the contractor and the client as introduced by the new Civil Code. Firstly, it points to a fundamental difference in the concept of ownership of land and buildings which will not be, unlike the current state, separate. Yet the law allows exceptions to this rule, which are briefly explained in the article.
The main part of the text deals with the issue that is most pressing in construction of buildings. It is the responsibility for the quality of the work or project documentation. The paper deals with the obligation of a client to accept work in stages, addressing liability for latent defects, acceptance of the finished with reservation of latent defects and etc. In this context it should not be overlooked, that the general liable for defective work are together the contractor, subcontractors, maker of the documentation and construction supervisor. These entities may waive liability only if they demonstrate that they did not cause the defect themselves.

One of the options for the treatment of coal tailings is production a new kind of artificial aggregate on the self-burning principle. The aim of the work was to demonstrate the possibility of using this aggregate in concrete structures. Subject of the paper are not only the results obtained after 360 days of ripening, but also to compare them with the properties commonly manufactured concrete.

This study was a part of the project for simulation of weather impact during long-term ageing of glass-fibre reinforced concrete composites containing waste on ecotoxicological properties (ekotoxicity) after 365 days from production and after 20 years of simulation of the product life cycle.

Application of the burning lime for masonry is known from the eldest ages. In history was empirically discovered, the properties of lime putties and mortars made from it can be modified adding various additives. Inorganic additives with latent hydraulic activity (natural pozzolana, thermal modified rocks) or organic additives (proteins, carbohydrates, organic acids as fruit juices etc.) were used. Beneficial influences of some additives were proven by contemporary science. Application of other additives seemed irrational from present point of view. The aim of this work was determined the influence of some historical additives on lime putties and mortar properties.

Paper will inform you about the results of a comparison of several hydrophobic additives. Building components based on plaster without special treatment generally have high water absorption (~ 30 %) and they are therefore not suitable for areas with high incidence of moisture, where they can be exposed to direct contact with water. The trend leads towards lighter building materials, which often leads to an increased proportion of open porosity and thus to increased absorption. A suitable solution is utilization of hydrophobic additive during the production of gypsum building elements. Appropriately chosen additive can significantly reduce water absorption, even at relatively low addition and high mass lightening of element.

The 70-ers and 80-bit of the last century were developed a number of standardized structural framing wood-based, which produced the then national wood processing plants. Several of these systems have been specifically developed for agriculture, in which wooden structures are preferably applied mainly for objects with increased aggressiveness environments such as. storage of fertilizers, stabling facilities etc. Some of these buildings still serve their original purpose even today, although their structures are weaknesses of different nature.

Timber-concrete composite structures which use advantages of both materials are suitable for new works and reconstructions of civil and residential buildings. There are described many methods of joining between timber beam and concrete slab in technical literature. Joints are more and more sophisticate which brings higher demands of work control and technology. Main goal of this paper is in design technologically low demanding method of joining with steel plates and nails, to test its shear strength and compare it with other similar joining method.

The paper is concerned with some selected defects and failures of timber structures and their rehabilitation. The paper summarises some conclusions from the construction and real behaviour of selected timber systems. Due to the fact that their load-carrying capacity and deflections are considerably affected by the load-carrying capacity of the joints, it was de-sirable to verify the influence of structural design of fasteners and connectors on the over-all behaviour of structural systems. Findings from behaviour of structures after their reha-bilitation are crucial for further research into real behaviour of timber structures.

The work describes the divisions of contemporary and traditional solid wood constructions. The introduction briefly explains the historical development of timber structures and the advantages that these structures provide. Individual structural systems are described according to the basic elements and usage possibilities. The requirements for the massive wooden houses are listed in the form of technical standards and laws that have to meet.

This paper deals with the basics of the so-called “Massive Timber Construction“ (MTC) system. The paper is focused to the design of MTC system (mainly design of floors, shear walls and connections) which is made from the relatively new wood-based product “Cross Laminated Timber” (CLT). CLT consists of several layers built-up with boards. Their assembly in orthogonal directions allow them to produce elements with big dimensions. Currently, no regulations for the design of CLT-elements are given in the European standards. Nevertheless mechanical parameters of CLT-elements can be determined on the basis of the properties of the single layers as is shown in the paper. It is expected that CLT will play an important role in the future use of wood in single and multi-storey buildings.

This paper deals with possibility of using recycled construction and demolition waste as aggregate for concrete. The European Standards describes tests and properties of recycled aggregate for concrete. The main aim of this investigation was determination of recycled aggregates properties and their comparing with properties of natural aggregate and requirements in Standards. Selected geometrical and physical properties were tested and results were used to design concrete mixture. It was found that the main differences between natural and recycled aggregate is water absorption. Water absorption of recycled aggregate was more than ten times higher.

A new type of circular wind bracing has been developed for stiffening of high-rise slender steel structures. This bracing can use pre-stress to modify its stiffness to achieve required properties. The models scalled 1/20 are subject to static and dynamic load laboratory tests in order to prove theoretical conclusions and to adjust optimal values of pre-stress.

This paper describes the experience gained in planning, design and implementation of rehabilitation reinforced concrete structure, which is formed in the lower part of the reinforced concrete skeleton, from 3.NP T06B wall system with regard to the loading of the next deck above.

Blocks for masonry with integrated insulation material are known over 30 years. Especialy hollow clay bricks have low U value due to optimalization of their geometry with low thermal conductivity of ceramic body. Finaly integrated insulation material into the holes in bricks results to increasing of thermal insulation properties. Article is focus on behavior of hollow clay bricks with and without integrated insulation material in dynamic heat load.
