New Civil Code enacts special type of solidary obligation to remedy the defects of building constructed under contract for works. All subcontractors (suppliers) of constructor, investor`s technical supervisors or construction project designer are solidary responsible together with the constructor in case the defect can be attributed to the performance they provided. However, these parties need not to be the parties to the contract for works itself (and usually are not) as their obligation arises by law.

The remedies that the investor can claim on these co-debtors, however, are limited to right to demand the repair of the defect. Investor may demand remedy on any of the co-debtors and all the co-debtors are obliged to perform the remedy in full.

The investor has to give notice to the debtor within a reasonable time. The notice can be sent to any of the co-debtors but we advise all investors to give notice always to the constructor first or together with the other co-debtors.

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.

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.

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.

The weakest part of concrete high-rise block are their envelopes, so most of regenerations are dealing with reconstruction of existing envelopes. It related of the replacement of window openings, the installation of additional contact thermal insulation or modifications of projecting structures, including loggia glazing and, last but not least, changes in the colour shading of the surface façade layer. These adjustments can improve energy efficiency of the building, but secondary negative effects on the interior environment in terms of the daylight level must also be considered. In this study we tried to take account of both width and shape of jamb of the window with taking into account the effect daylight inside the room.

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 term “ancillary materials” covers a wide range of products (mouldings, profiles etc.) which significantly influence the overall quality of works. As legislation normally does not require any verification of performance and no relevant standards exist, verification and declaration of performance is usually omitted. In reaction to that, we have specified characteristics and verification methods for adequate and consistent verification of relevant characteristics in the framework of voluntary certification.
