5) schedule of receipt of ventilation blanks (ducts and standard ventilation parts) to the facility;

6) the schedule of receipt of ventilation equipment, agreed with the customer;

7) calendar (network) schedule of work with deadlines for the delivery of the object;

8) statement of basic and auxiliary materials;

9) instructions on methods and methods of installation work and safety;

10) a statement of the necessary mechanisms, tools and means of small mechanization specifically for the object;

11) production calculations and summary statements of labor costs and wages;

12) the schedule of the need for workers.

In the calendar (network) schedule of work, the deadlines for preparing the object or individual premises for installation, the deadlines for the completion of construction work in ventilation chambers, the deadlines for the supply of electricity to ventilation equipment and hot water to heaters and, most importantly, the deadlines for the installation of ventilation systems should be determined. A schedule for the delivery of ventilation equipment to the facility must be agreed with the customer's organization in advance.

For objects with a small amount of ventilation work and capital repairs, abbreviated The project of work production is the basic guide for the organization and production of installation work at the facility. Project of work production helps to plan all the preparatory work, including the execution of orders for air ducts and applications for ventilation equipment and materials, to determine the storage locations of bulky ventilation parts. The project of work production contributes to the uninterrupted conduct of installation work, improving the quality of installation.

Prior to the start of installation work on the object or on its part, a list of individual types of construction works, the performance of which is necessary for the subsequent installation of ventilation systems, and the timing of their execution must be agreed between the representatives of the installation organization and the general contractor.

Such works include:

1) installation of foundations, platforms and other supporting structures for ventilation equipment;

2) installation of walls and partitions in ventilation chambers, as well as ceilings, if the project of work production does not provide for the supply of ventilation equipment through the top of the chambers;

3) installation of embedded parts provided for by the project in ventilation chambers for connecting ventilation equipment and along the route of systems for fixing air ducts;

4) installation of horizontal and vertical mounting openings for the supply of ventilation equipment and ducts from an on-site warehouse to the place of their installation;

5) installation of walls and ceilings in the places of laying air ducts;

6) plastering and painting of walls, ceilings and partitions in the places of laying air ducts and installing air distributors;

7) punching holes in places where air ducts pass through walls, ceilings and partitions, if they are not left during the construction of the building;

8) installation of reinforced concrete cups on floors in places of passage of ventilation shafts and installation of roof fans;

9) the device of fasteners for large-sized air ducts and platforms for cyclones, scrubbers, filters, etc.;

10) the device of ventilation ducts in construction (brick, concrete);

11) glazing of window openings and lanterns

12) cleaning of ventilation work sites from construction debris.

After performing these works on the entire object, the object is accepted under a bilateral act for installation. It is especially necessary to carefully prepare the rooms of the ventilation chambers, where all construction work (except clean floors and final painting) must be carried out and the lifting devices provided for by the project for the operation and repair of ventilation equipment must be installed. For the passage of air ducts through building structures, the holes in them must be 150 mm larger than the diameter of a round or the dimensions of the sides of a rectangular air duct.

By the time the installation works begin, the general contractor must provide the installation team with:

a) cabins for workers, a room for a workshop and a storeroom, open storage areas and sheds for storing air ducts, ventilation equipment and products in the area of operation of vehicles;

b) supply of electricity, water and heat during the cold period for the production of works and for domestic premises;

c) vertical and horizontal on-site transport;

d) electric lighting in places where ventilation works are performed;

e) fire and guard protection.

To perform installation work directly on the site, it is necessary to have the following technical documentation:

1) two copies of working drawings;

2) a set of installation drawings or sketches for all ventilation systems;

3) a project for the production of works with standard technological maps;

4) the list of ventilation equipment and materials supplied by the customer (non-standard equipment, alloy steel, etc.);

5) the act of acceptance of the object for installation.

After acceptance of the object for installation, mounting devices (ladders, towers, traverses, blocks, scaffolds, etc.), mounting mechanisms, electrified tools, welding equipment and tool kits are delivered to the object.

Air ducts of ventilation systems are manufactured only according to installation drawings or sketches. Installation drawings are carried out on the basis of working drawings of ventilation systems.

Installation drawings contain:

a) an axonometric diagram of each ventilation system, made without a scale in one line, indicating the dimensions of the cross-sections of the ducts, the number of each part, marks and bindings of the ducts to the axes and surfaces of building structures;

b) a complete list with a list of all parts, their dimensions, characteristics, quantity;

c) sketches of non-normalized shaped parts of air ducts with all the dimensions required for their manufacture;

d) the scope of work and specification of materials and standard components, including the type and number of fasteners.

Installation of fans up to and including No. 12 is carried out in the following sequence:

1) check the prefabricated structures on which the fan should be mounted;
