TECHNICAL PART
1. General instructions
1.1. These State Elementary Estimate Standards (GESN) are intended to determine the need for resources (labor costs of workers, construction machines, materials) when performing thermal insulation and fire retardant work and to draw up estimates (estimates) using the resource method.
GESN are the initial standards for the development of unit prices, individual and consolidated standards (prices).
1.2. GESN reflect the industry average costs for the operation of construction machinery and mechanisms, technology and organization by type of construction work. GESN are mandatory for use by all enterprises and organizations, regardless of their affiliation and forms of ownership, carrying out capital construction with the involvement of funds from the state budget of all levels and targeted extra-budgetary funds.
For construction projects financed from the own funds of enterprises, organizations and individuals, GESN are advisory in nature.
1.3. Norms sectionI of this Collection are intended to determine the resource requirements when performing work on insulating hot surfaces of pipelines, fittings and flange connections; equipment, apparatus, reservoirs (containers), turbines; ventilation and air conditioning systems, as well as cold surfaces of building structures.
1.4. Norms sectionII The collections are intended to determine resource requirements when performing fire protection work on all types of building structures, fabrics and carpets, glass surfaces, cables and cable penetrations.
1.5. Norms table 01-037¸ 01-041 designed to insulate cold surfaces. Norms table 01-42 provide for the installation of doors with thermal insulation.
Norms table 01-037 provide for the use of products made of cellular materials (foam concrete, aerated concrete, expanded clay concrete), table 01-038¸ 01-040 products made from fibrous and granular materials (hard mineral wool, perlitobitumen, asbestos-vermiculite and perlitohelium boards), table 01-41 foam products.
Norms table 01-037 designed taking into account the use of foam concrete slabs; in the case of using aerated concrete or expanded clay concrete slabs, a coefficient of 1.03 should be applied to labor costs.
Insulation of cold surfaces of pipelines and equipment should be taken in accordance with the relevant standards for the insulation of hot surfaces of pipelines and equipment.
Standards for insulating cold surfaces with thermal insulation products do not take into account the costs of installing a vapor barrier layer.
The design of the vapor barrier layer should be taken as follows:
a) when insulating walls and columns - according to the standards of the collection GESN-2001-08"Brick and block structures";
b) when insulating floors - according to the standards of the collection GESN-2001-11"Floors";
c) when insulating coatings - according to the standards of the collection GESN-2001-12"Roofs";
d) when insulating pipelines and equipment - according to the standards of the tables: 01-054 - rolled materials (roofing felt, glassine), 01-055 - polyethylene film.
Standards 1,3,4 table 01-038; standards 1,3,4 table 01-41 the costs of installing a wooden frame to strengthen the thermal insulation are taken into account.
1.6. The standards for pipeline insulation are drawn up for the insulation of pipes with a diameter of up to 820 mm and apply to the insulation of cylindrical surfaces of equipment, as well as fittings of the same diameter. For large diameters, the standards for insulating flat and curved surfaces should be applied.
1.7. The need for resources when insulating flat surfaces with mineral wool slabs of grades 150-200, as well as rigid slabs of other types and brands provided for by the project, should be determined according to the standard tables 26-01-005-4.
1.8. Brands of thermal insulation materials, structures and products should be taken according to design data.
1.9. The additional consumption of heat-insulating materials and products associated with sealing when installing them on an insulated surface is taken into account by standards in accordance with SNiP 2.04.14-88"Thermal insulation of equipment and pipelines."
When using thermal insulation materials and products with compaction coefficients different from those accepted by standards, their consumption should be determined by design data.
1.10. Norms tables 01-012, 01-013 insulation of fittings and flange connections on pipelines is provided.
Norms tables 01-014 provide for insulation of fittings and flange connections on equipment.
1.11. The amount of work in m 2 per 1 m 3 of insulation when installing a protective coating for pipeline insulation with polyurethane foam by pouring is determined by design data or calculation ( clause 2.9 Technical part).
The weight of 1 m 2 of metal coating 1 mm thick, taking into account manufacturing, is: for aluminum - 3.48 kg, for galvanized steel - 9.58 kg.
1.12. Norms table 01-020, 01-021 Insulation with polyurethane with a density of 60 kg/m 3 is provided. The ratio of components A:B is 1:0.96. For other specified values of insulation density, the consumption of components is determined by the design.
1.13. V table 01-056 The accepted thickness of the plaster layer is 10 mm. For other thicknesses, the consumption rates of machines and materials should be changed in proportion to the change in layer thickness, the labor cost rates should be increased by 14% for every 5 mm increase in thickness.
1.14. The coloring of isolated surfaces should be taken according to the standards of the collections GESN-2001-15"Finishing work" and GESN-2001-13"Protection of building structures and equipment from corrosion."
1.15. Norms table 01-05, 01-024 for the insulation of flat and curved surfaces with lime-silica slabs and asbestos-perlite insulation of boiler units and auxiliary equipment using the spraying method, the manufacture and installation of fastening frames are not taken into account. The arrangement of frames provided for by the project should be taken additionally.
1.16. The standards for pipeline insulation do not provide for the installation of unloading devices in vertical and inclined sections and support rings in horizontal sections. The costs of installing unloading devices and support rings should be taken according to the standards tables 01-023.
1.17. Standards 1,2,3 tables 02-003 fire-retardant coating of load-bearing metal structures, floor beams, coverings and trusses is provided with the OFP-NV "ESCALIBUR" composition with a reduced metal thickness of 3.4 mm and a coating layer thickness corresponding to this fire resistance limit.
For other values of the given metal thickness, the thickness of the fire-retardant coating, depending on the required fire resistance limit, should be determined by table 1.1 Technical part.
