Assessors often encounter objects with uncertain structural system. These buildings are designed with difficulty and in its operation they may behave differently than expected. Good design and implementation are, in the case of long-term behaviour of structures, essential. The article deals with the basic principles of proper design and its assessment.

The basic document for the area of construction products was until the April 2011 Council Directive 89/106/EEC (CPD). On 4st. April 2011 was published in the OJ EU REGULATION OF THE EUROPEAN PARLIAMENT AND COUNCIL No 305/2011 which defines harmonized conditions for the placing of construction products to EU market and cancels Council Directive 89/106/EEC.

Prefabricated single-storied concrete assembly hall is roofed with prestressed lattice girders, skylights, purlins and roof slabs. Significant problems of a roof structure were found out. The method and results of examination and the principles of reconstruction are described.

In connection with the implementation of the revised European Directive 2010/31/EU on the energy performance of buildings, certain legislative provisions such as Decree No. 148/2007, Coll. Replaced by Decree No. 78/2013, Coll. are currently amending. This article is focused on the changes associated with the energy certification of buildings, the "ENB", from the perspective of changes in the evaluation ENB.

This paper describes an investigation of historical timber members of roof structure at Masaryk railway station in Prague. In the paper is also presented an experiment, which deals with the influence of mechanical damage to timber members in the interpretation of the results of non-destructive measurement.

It has been one year and a half since Technical Standards Information TNI 74 6077 – The windows and external doors – Requirements for incorporation has been published. What is the consistency or inconsistency between the demands on windows and doors manufacturing, their installation and actually reached geometrical tolerances of building construction? What this state brings to manufacturers of windows and doors, what to building contractor and what to customers? The view through the eyes of quality control.

This paper reports the results of research, which is aimed at determining the formation and development of cracks from rheological processes at an early age in various types of concrete. Individual recipes differ in the value of the coefficient of water and also the type of fibers.

This paper deals with the classification of test properties of windows and entrance doors in terms of usability for practical use. Those classification classes are very important for the use of acquired functional properties of hole filling for use of the products in the country. Based on the above, it is then possible to determine the specific levels of performance that should be achieved by a product to demonstrate suitability. In summary, attention is also focused on technical thermal and acoustic properties of hole filling in terms of usability for additional practice.

The paper deals with the development of the magnetic method using permanent magnets for monitoring the distribution of fibers in hardened steel fiber-concrete structures and comparative measurements on test samples.

This paper deals with methods for determining the reliability of historical wooden structures and tries to outline the progress and shift in the methods used, problems or gaps in knowledge and research needs associated with this activity.

Wood is an organic material and therefore often considered to have a short lifetime. However, in the past, people did not distinguish between durability of wood and durability of masonry, proof of which is the existence of constructions that combine the use of both. In fact, the lifetime of wood can be high if specific rules are followed when designing the construction.

This paper describes the method for calculating the amplification of curved brick construction with composite reinforcement and compares this procedure with reinforcement made by conventional methods to gain a practical demonstration of the bent beam.

This paper presents an analysis of the behaviour of wood when using the diagnostic tool for "in-situ" assessment of wood based on the principle of mechanical resistance to penetration tool (mandrel) into the wood. The aim was to describe the degree of deformation and failure mode during penetration (diameter 2.5 mm) into wood in a purely radial direction and to compare the tool with a standard measurement unit testing on samples.

Benchmarking is a continuous and systematic comparison of own performance in productivity, quality, and manufacturing process, with enterprises and organizations representing excellence. "Benchmarking is the process of identifying best practices in other organizations and learning from them."

To calculate the fastening plan of mechanically fastened waterproofing roof sheet (MEFAWAME) it is necessary in addition to the correct wind suction procedure also determine by the corresponding way the resistance (allowable stress) of the fasten system.

Wood-destroying insects is one of the biological wood pests. Attacks the wood material, both individually and also in parallel with other decaying biological pests. Knowledge of principles for the design and implementation of a hot air disposal of wood-destroying insects is necessary for the reconstruction of historic buildings. Carefull consider from a conceptual point of view is necessary for the design for redevelopment of wooden elements affected by wood-destroying insects.

The paper deals with structural and humidity survey of the timber-framed building of Rowing Centre from the 19^th century in Brno. The building is one of the last surviving buildings of its kind in the city. The results of the survey of wooden structures, including windows, doors, and other construction, can be summed up in a statement that the construction is in relatively good condition adequate to its age. Proposal of preventive and remedial actions aims at maintaining of the traditional timber-framed system with the supporting structure visible from the outside.

The paper describes the circumstances that often lead to disputes about result quality of industrial floors. In addition to quantitative parameters, such as flexural rigidity of plate, coating adhesion to the surface layer and local flatness, attention has always focused on the appearance of the visible surface. The paper proposed assessment methodology that would allow at least partly quality assessment of the coating as a whole objectify and create all interested parties basis for fair negotiations.

The CE mark indicates only that the specified product properties were tested in accordance with specified regulation, in the case of windows, the type test was performed for 1 pcs of the product. Subject to the same quality parameters, ie same values ​​of air permeability, watertightness, etc. for the entire manufacturing production is the only producer responsibility.
