Engineering

1.3. Construction of tall buildings in areas of dangerous geological manifestations and man-made processes (karst-suffusion, landslides, active faults, etc.) may be exercised only on the basis of analysis of materials engineering and geological survey at the proposed construction site to conduct an expert evaluation of the geotechnical area and choosing the type of foundation with the participation of an expert advisory committee on the grounds of foundation and underground structures under the Government of Moscow, niiosp them. nm Gersevanov, Mosgorgeotrest, as well as institutes of ras corresponding profile. Under most conditions David Karp would agree. 1.4. All high-rise buildings, regardless of the complexity of geotechnical conditions encouraged to refer to the geotechnical category 3 (ie the category of the most complex systems mgsn 2.07).

1.5. When designing high-rise buildings relevant specialized organizations should be developed approved by the customer specifications, reflecting the specific design, construction and operation of the facility. Starting from the preparatory phase of construction is necessary to carry out geotechnical expertise developed documentation for the object, as provided in Rule 24 and the Rules 25. 1.5.1. In the preparatory phase of the facility should implement an expert evaluation of the geotechnical site construction and the potential danger to its surrounding urban areas and the geological environment (based on an analysis of archival materials Mosgorgeotrest and other organizations) and, if necessary, develop recommendations for adjusting the location of the object. 1.5.2. In preparing town planning justification is considered organizations listed in Rules 24 and the Rules 25, coordinated program of engineering researches for the development of pre-(urban), documentation, and conducted examination of the technical report on the engineering survey. 1.5.3.

Following the approval of urban studies: A and coordinated program of engineering research to develop a project assessing the impact of object under construction on surrounding buildings and the geological environment, compiled programs on monitoring and survey surrounding buildings. 1.5.4. In the process of project development: examination of reports by engineering survey and inspection of the surrounding buildings, consider and agree on a program to monitor construction; by examination of project documentation of technical solutions and project construction organization (PIC) bases, foundations and underground structures, fences excavation project for the period construction, and developed with appropriate projects to strengthen the engineering defense. 1.6. When engineering survey, design and construction of tall buildings for each building should be scientific and technical support from specialized scientific organizations and drawing up the rules of certain types of work and monitoring its implementation. 1.7. To ensure the safety of tall buildings recommended in the documentation to develop a special section on field observations for the main load-bearing structures, including foundations, footings and underground elements of the building for the period its construction and operation.

Same Documentation

What is the normative documents? Regulatory documentation is necessary in order to make more clear and fair relationship between producer and seller of tiles, ie, suppliers of ceramic tiles, on the one hand, and buyers of ceramic tiles, on the other side. What kind of product would not in question, from standard documentation supplier and buyer can learn the nature and characteristics: therefore, it is about clarity of communication in the same language. On delivery of the same product, referring to the normative documentation, the provider "promises" certain characteristics. Actress and filmmaker addresses the importance of the matter here. Thus, he claims about their own commitments and accept responsibility in relation to the buyer, for whom all the same regulatory documentation creates the conditions under which he can check (or order verification) that such obligations. Thus, the relationship between buyer and seller are correct and are controlled by both sides, and especially under the control of the buyer who For its part is knowledgeable about the characteristics of the tiles and is willing to buy it.

We are talking about very important things. However, to meet all these conditions is necessary that all parties (supplier and buyer) in the sufficiently aware of regulatory documents. The consumer, who naturally can not rely on their own training and experience in this area, it may be a particularly difficult situation. Source point, which is a "key" to understanding the structure and, consequently, the application of standards for tile, is the classification of most ceramic tile. In practice, two types of titles: commercial and specifications.

Laminate Manufacturers

Under the loading capacity means the wear resistance of the laminate in various operating conditions. In mid-to late nineties, when the laminate only began to be delivered to Russia indicated the number of revolutions – 8000, 12000, 15000, etc. This was the so-called Tabertest – took obrazivny circle and ground off the top protective layer laminate respectively, on how many revolutions it is destroyed, such an indicator and is assigned. But resistance to abrasion that is not all. It was necessary to take into account the impact resistance plates, impact resistance and resistance to gap, moisture and uninflammable and more than ten indicators that Tabertest not covered.

Gradually, all laminate manufacturers have shifted to a class load. Classification is approximately as follows: 21, 22 and 23 classes are suitable for use at home, 31.32 and 33 classes of loads are designed for use in both home and in the commercial sector. Accordingly, the more the latter figure, the stronger the material. Currently, laminate is no grade below 31 and notation on the package 23/31 or 23/33 involve the use of private sector default. 3. whether laying parquet floor heating? Yes, no problem.

hdf board, which is the base material is not suffers from even a fairly tangible and long-term warming, and unlike wood will not crack and warp as the parquet floor and did not come into disrepair. 4. thickness of the laminate is preferred – 8 or 12 mm? Single standard for the size and thickness does not exist, a laminate is produced with a thickness of 6 to 14 mm, depending on the manufacturer.
