The cost of constructing a dam, drainage structure, irrigation network and sprinklers is determined according to local estimates 1, 2 (Tables 6 - 7) and a consolidated cost sheet (Table 8).
1. The volume of cutting of plant soil from the base of the dam is determined by the formula:
Vdis.pl. = F0*hrast,
where: F0 - dam base area, m2;
hrast.s. - cutting thickness of plant soil is 0.3 m.
F0=*=6922.9 m2;
Vdis.pl=6922.9*0.3=2076.87 m3
2. The volume of cutting of plant soil from the surface of the quarry is determined by the formula:
V rast.k. = Fkar. hrast.k.,
where: Fkar - quarry area in plan, m2;
hrast.k. - cutting thickness of plant soil is 0.5 m.
where: Vkar is equal to the volume of the body of the dam under construction, m3;
hkar - depth of quarry development, 8...10 m.
Hence Fkar==8423.65 m2;
Vdist.k=8423.65*0.5=4211.83 m3.
3. The volume of cutting of plant soil from the surface of the discharge structure according to the formula:
Vrast.s. = La*hrast.с *(в + m*h),
where: La = length of the spillway channel, m;
в - width of the channel along the bottom, m;
m - laying of canal slopes, m;
h - channel depth, m.
Vdis.s.=77.5*0.3*(11.5+1*2)=267.4 m3.

A dam is a hydraulic structure erected to fence artificially created reservoirs and watercourses, raise the bank of a natural watercourse, change the direction of flow and protect the area from flooding. Five main requirements for dams:
Unlike industrial and civil structures, hydraulic structures During operation they are exposed to various factors associated with water - mechanical, physico-chemical, biological. The more thoroughly the survey work is carried out, the more accurate the designers’ calculations will be. What types of surveys and studies need to be carried out before the start of design work:
After conducting surveys, during which data on the terrain will be obtained, its geological structure, level of occurrence groundwater and watercourse conditions, a multi-stage design process begins. It includes preliminary, working and control stages. What tasks are set for designers?At preparation of the dam project Region specialists consistently solve the following tasks:
Dam project priceThe initial cost of estimate and design documentation is determined on the basis regulatory framework pricing. Basic prices are multiplied by a coefficient that takes into account the current market situation. The individual features of each project are clarified during a constructive conversation with the client. Our company assumes warranty obligations and bears financial responsibility for failure to meet deadlines.
We always include warranty obligations as part of the design contract. Region LLC specialists are ready to provide assistance at all stages of decision-making, both at the stage of considering the project concept and when considering options for the reconstruction of existing buildings and structures. At the design preparation stage - prepare technical specifications for design and the necessary research.
