Technical part

1. General instructions

1.1. These State elemental estimated norms ( GESN) are designed to determine the need for resources (labor costs of workers, construction machines, materials) when performing a full range of basic, auxiliary and related works necessary for installing the main types of floors and drawing up cost estimates (estimates) using the resource method. GESN are the initial standards for the development of unit rates, individual and aggregated rates (prices).

1.2. GESN reflect the average industry costs for the operation of construction machines and mechanisms, technology and organization by type of construction work. GESN are obligatory for application by all enterprises and organizations, regardless of their affiliation and form of ownership, carrying out capital construction with the involvement of funds from the state budget of all levels and target extra-budgetary funds.

For construction projects financed at the expense of own funds of enterprises, organizations and individuals, GESN are recommendatory.

1.3. When installing chemically resistant floor coverings for rooms with aggressive environments, as well as when installing coatings and insulating trays and channels, the norms of the collection GESN-2001-13 "Protection of building structures and equipment from corrosion" should be used.

1.4. When installing screeds ( tab. 01-011 norms 1, 3, 5) to take into account the aggression of soil to concrete, the following resources should be added:

To the labor costs of workers - 1.09 man-hours;

For the operation of machines - bitumen boiler (code 121011) - 1.09 machine-hours;

To materials - bituminous mastic (code 101-0594) - 0.134 t.

1.5. When cutting vegetable soil, use the norms of the collection GESN-2001-1"Excavation".

1.6. Norms 2-8 tables 01-002 and norms tab. 01-003 are applied both for the device of underlying layers, and for the device of coverings.

1.7. When constructing a concrete underlayment with concrete-laying machines, in accordance with the rules for constructing cement-concrete road surfaces, the norms of the collection GESN-2001-27 "Motorways" should be used.

1.8. Rules 7 and 8 tab. 01-015 may be used only if there are instructions in the project.

1.9. Norms 1, 2 and 4 tab. 01-036 and norms 1-4 tab. 01-037 provide for the laying of linoleum, relin and carpets of plain (without a pattern) and colored (with a pattern) that do not require adjustment of the pattern at the joints. When laying linoleum, relin and carpets with a pattern that requires adjustment of the pattern at the joints, it is necessary to apply the coefficients of clause 3.3 of this technical part.

1.10. The norms for the installation of coatings do not take into account the cost of installing skirting boards, which should be taken additionally according to the relevant norms of the collection, depending on design decisions.

1.11. The “up to” size listed in this collection includes this size.

2. Rules for calculating the scope of work

2.1. The volume of the underlying layer (preparation) for floors should be calculated minus the space occupied by stoves, columns, protruding foundations and similar elements.

2.2. The scope of work on the installation of floor coverings should be taken according to the area between the inner edges of walls or partitions, taking into account the thickness of the finish provided for by the project; coatings in window sills and doorways are also included in the scope of work and are calculated according to design data.

The areas occupied by partitions (except for clean ones), columns, stoves, foundations protruding above the floor level, and similar structures are not included in the scope of work.
