Application of BIM Process by the Evaluation of Building Energy Sustainability

The use of building information modeling (BIM) in the Czech Republic is currently at the stage of being slowly established in the Czech building environment. From the viewpoint of applicability in the building industry, the issues of BIM in the Czech Republic are very desirable, mainly because of ever-increasing pressure on the sustainability of construction. This approach is gradually used by some, often multinational, construction companies. The article focuses on finding the possible optimization of approach to the planning and operation of buildings in terms of the energy sustainability of buildings.

Assessment and Damage for Building Structures Risk Analysis Methods

The paper introduces an alternative method for damage pricing on buildings in consequence of defects, failures and collapses. The method operates with time-independent price of the structure and following damage on the construction. Using risk analysis methods, the price is reduced depending on technical condition to proper damage and evaluation of the object, building or structure.

Risk Analysis of Foundation Structures According to the Method of Founding

Like the foundation structure, their proper design and good execution plays an important role in the issue of durability of structures, it is also very important to properly design and implement the base layer of foundation structures. Usually, the base layer formed viable subsoil, which are located in the subsoil. Substructure then form the base layer interaction system. The subsoil is not always such a layer that would allow the establishment directly to solid ground. Also, the material (mass concrete, reinforced concrete) foundation structures determines whether it is possible to establish a building directly on the hard soil or underlayer is necessary. Often such a base layer performs building materials arising as waste during mining (eg. coal) or as waste generated in blast furnaces (slag). Often the buildings are well established on the embankments. Individual types of base layers (subsoil) will be evaluated by a team of experts. The team consisted of 43 experts. These experts conducted an evaluation of each type of subsoil individually using the universal matrix of risk analysis - Umra. Umra method is based on the principle of comparative logical and numerical analysis assessing the degree (severity) of a danger to the the project or its component parts. A team of experts assesses the identified part of the problem (the project), which is subject to a certain risk. Number of parts of the problem evaluated by a team of experts is arbitrary, with different (or identical) parts can be handled independently by different expert teams with different number of experts.

Utilization of Risk Analysis Methods in Decision-Making Process on Fitness of Rehabilitation

The paper reflects the possibility of utilization of methods and proceedings used in risk assessment for area different from nowadays usage. Risk determination is customary for large and significant constructions within the feasibility study. Used procedures and methods can be applied very well in some cases of experts and authorized proceedings, such as setting the sequence of buildings acceptable for reconstruction of objects in defined group, or setting the coefficient for specification of claim amount arisen in the construction in the case of time-independent price.

Instruments for Risk Analysis as an Alternative Decision-Making Method in the Forensic Sciences

The paper introduces an alternative method for damage pricing on buildings in consequence of defects, failures and collapses. The method operates with time-independent price of the structure and following damage on the construction. Using risk analysis methods, the price is reduced depending on technical condition to proper damage and evaluation of the object, building or structure.

Application of Risk Analysis by the Evaluation of Buildings Indoor Environment

In civil engineering we face up to a wide line of risks of mostly technical character (accident hazard, formation of damages or defects). At present a continuous tightening of cladding energy parameters happens within the sphere of residential and civic engineering. With buildings built in the end of the past century it is not possible to meet completely these requirements without a considerable intervention (and not only into the cladding). Risks acting to users of such objects resulting from its use can be evaluated using the risk analysis method.

Risk Analysis of Asbestos Structures and their Impact on the Internal Environment of Buildings

Asbestos products were abundantly used in the civil engineering in 70s and 80s. In some objects they still persist till nowadays namely in office and school buildings where they represent a health risk for people who stay in such premises on a long-term basis. These products have very often negative impacts on health of users of such premises. They negatively influence the internal environment of buildings and its hygienic aspects. One of the possible ways of risk rate evaluation of these aspects on man is using the application of risk analysis.
