The company offers a comprehensive analysis of engineering survey materials and project documentation. Experienced specialists will help in the preparation of technical specifications at all stages of project development. Independent support of the project preparation process by our specialists will help to timely identify shortcomings in the developed documentation, successfully pass the examination and optimize costs in the future stage of construction.
Experience shows that often the performers make mistakes at the stage of engineering surveys, which leads to incorrect design decisions, problems with the passage of expertise and the rise in the cost of construction.
The most expensive is the correction of errors made in the design of the bases and foundations. One example is to allocate unequal settlement of the foundations. The reasons, for example, may be errors made in the process of research, design or errors at the stage of excavation.
Significantly reduce costs at the stage of "zero cycle" of construction work will help competent project of earthworks.
As an example, we can cite the most common comments from experts:
Schemes of the planning organization of the parcels of land go beyond the boundaries of the allocated site or beyond the zone of admissible placement of capital construction objects designated in gpzu;
Situational plans are often presented without justification of the boundaries of sanitary protection zones of industrial facilities, transport communications;
When grading the sewage provides for violations of the technical requirements for the improvement;
Incompleteness and unreliability of data in engineering surveys, including the survey of the technical condition of the structures of buildings and their bases to be reconstructed, leads to incorrect design decisions to strengthen them;

The assessment of influence of dynamic influences on deformation of the bases of the existing buildings located near the hammered piles or located near the ditch which is subject to ramming by means of rammers is not represented (article 35 of the Federal law of 30.12.2009 No. 384-FZ "Technical regulations on safety of buildings and constructions»);
Measures are provided for the preservation of soil cover, which are not confirmed by the results of engineering and environmental surveys, or the results of engineering and environmental surveys revealed the presence of soil on the site, and measures for its protection are not provided;
As a part of section there is no assessment of impact of the planned activity on water biological resources and their habitat (the subparagraph "point 2 of Regulations on measures for preservation of water biological resources and their habitat", part 3 of article 32 of the Federal law of 10.01.2002 No. 7-FZ "About environmental protection", points 25, 40 of Regulations on structure of sections of project documentation and requirements to their contents approved by the order of the Government of the Russian Federation of 16.02.08 No. 87);
There is no coordination of project documentation by territorial authority of Federal Agency for fishery (part 1 of article 50 of the Federal law of 20.12.2004 No. 166-FZ "About fishery and preservation of water biological resources»);
Placement of the generated waste on unlicensed objects of placement of waste is provided (article 9 of the Federal law of 24.06.1998 No. 89-FZ "About production and consumption waste»);
Requirements of sanitary rules and norms to the place of placement of objects of production, utility, transport, trade, public catering which are sources of impact on the environment and human health and demanding definition of borders of sanitary protection zones (SPZ) are not considered, the underestimated sizes of SPZ are unreasonably accepted because of wrong classification of object without technology of work, indicators of power, productivity and so forth; requirements to the mode of the territory of the sanitary protection zone are violated;
When designing water supply facilities, the size of the sanitary protection zones of the water source is not coordinated with the Rospotrebnadzor authorities; the water treatment technology is adopted without a detailed study of the water quality of the source and its seasonal changes;
For the design of industrial enterprises: the project documentation does not work out noise protection, do not calculate the levels of artificial light in the premises with visual works, do not solve the problems of mechanization of labor-intensive processes;
Channel thermal networks and thermal cameras, located under the driveways, are accepted designs with insufficient load-bearing capacity;
Laying of the gas pipeline is provided at a distance less required from the foundations of buildings (reduction of the normative distance in seismic areas is allowed no more than 25%) (paragraph 5.1.1 SP 62.13330.2011);
Installation of the tripping device provided in the buffer zone of high-voltage transmission lines (paragraph 4.45 SP 42-101-2003);
