An example of an estimate for laying a telephone network. State estimated standards are enlarged standards for the cost of construction of external communication networks. to the order of the Ministry of Construction and Housing and Communal Services of the Russian Federation

One of the main engineering systems are communication networks. They are also sometimes called low-current, since information currents pass through them, and not power ones. The voltage of such networks can be about 12 to 24 V. When installing external communication networks, it is necessary to take into account the basic requirements that apply to them:

affordable cost;
high reliability;
scalability;
non-failure operation.

Before laying such engineering systems, it is necessary to correctly develop an estimate for the installation of external networks. Only specialists will be able to calculate everything accurately and without errors, therefore, compilation services budget documentation It's best to order from them. A lot will depend on the qualifications of the contractor, so the search for an estimator must be approached as responsibly as possible.

Features of installation and budgeting for communication

Low-voltage networks today make it possible to create:

cable structured systems;
access to the global network;
local computer networks;
alarm systems;
systems that control access to protected objects;
intercoms and much more.

When drawing up an estimate for a communication network, it is necessary to calculate all the costs of installation and other work. It could be:

installation of metal and wire trays;
organization of external communication channels between floors;
conducting commissioning;
connection of external and internal sockets.

All this should be included in separate items when drawing up the estimate documentation.

In addition, it is very important to design the communication network to be installed. AT without fail location must be specified:

low current relay;
low current shield;
sockets and other components.

We must not forget that all commissioning work must be carried out in accordance with approved rules and standards. The same applies to the calculation of estimates for the communication network - everything should be calculated as accurately as possible. This can only be done in budget bureaus, where professionals in their field work. True, some independently carry out commissioning of equipment and calculation of estimates, but without some experience this is impossible to do.

Who can make an estimate for laying a communication network professionally and at an affordable price

We should never forget that during the laying of communication networks, only high-quality equipment should be used. This applies to:

server cabinets;
cross equipment;
computer and telephone sockets;
mounting boxes and everything else.

Accordingly, all this should be taken into account when developing the budget.

The best estimators can be found on the Yudu website. Only proven performers are registered here, who are able to quickly and competently calculate the budget of the event installation work. You can order such services at the price that the customer is able to pay. Of course, each artist has their own prices, but they are not final.

STATE ESTIMATE STANDARDS

ENHANCED CONSTRUCTION PRICE STANDARDS

NCS81-02-11-2014

Part 11. External communication networks

TECHNICAL PART

1. General instructions

1. The state aggregated construction price standards (hereinafter referred to as NCS), given in this collection, are intended for planning investments (capital investments), evaluating the effectiveness of the use of funds allocated for capital investments and preparation of technical and economic indicators in the assignment for the design of external communication networks, the construction of which is financed with the involvement of federal budget funds. 2. NCVs are calculated in 2014 prices for the base region (Moscow Region). 3. Aggregated standards represent the volume Money necessary and sufficient for the construction of 1 km of external communication networks and 100 m of cable crossings under automobile and railways. 4. The collection provides for aggregated standards for the following nomenclature of external communication networks:

Section 1. Underground laying cable lines connections.
Section 2. Air laying of cable communication lines.
Section 3. Crossing the cable communication line under the road, railways.

5. The collection provides for the cost indicator: - 1 km of the route, 100 m of cable crossings. 6. Indicators of the aggregated standard for the price of construction take into account the following costs:

earthworks for trenching, with backfilling and layer-by-layer compaction,
installation work on laying cables in a trench, existing cable ducts, existing collectors;
construction work on the installation of supports for aerial laying of communication lines:
installation of straight, optical couplings;
testing of dielectric strength of insulation and measurement of crosstalk attenuation on paired cables;
work on the device of the transition under the highway, railway tracks using the horizontal puncture method;

7. The standards are developed on the basis of resource-technological models, which are based on design estimates for representative objects. Design and estimate documentation representative objects has a positive conclusion of the state examination and is developed in accordance with current regulations design. 8. The indicators take into account the entire range of costs that are provided for by the current regulatory documents in the field of pricing to perform the main, auxiliary and related stages of work for the construction of external communication networks in normal (standard) conditions, not complicated by external factors. 9. The given indicators provide for the costs of construction of facilities, including the cost building materials, labor costs for workers and the operation of construction machines (mechanisms), overhead costs and estimated profit, as well as the costs for the construction of temporary title buildings and structures and additional costs for the performance of work in the winter, costs associated with the receipt by the customer and the design organization of the initial data, specifications for the design and implementation of the necessary approvals for design decisions, insurance costs for construction risks, costs for design and survey work and project expertise, maintenance of the construction customer service and building control, reserve funds for unforeseen work and costs. 10. The cost of materials takes into account all costs (sales prices, margins of supply and marketing organizations, costs for containers, packaging and props, transport, handling operations and procurement and storage costs) associated with the delivery of materials, products, structures from bases (warehouses ) contractor organizations or supplier organizations to the on-site construction warehouse. 11. Remuneration of labor of construction workers and workers, managers construction machines, includes all types of payments and remunerations included in the wage fund. 12. Aggregated standards do not take into account construction costs and, if necessary, may be taken into account additionally: other costs of contractors that are not related to construction and installation works (travel expenses, transportation of workers, expenses for maintaining rotational camps), payment for land and land tax during the construction period. 13. Compensation payments related to the preparation of the construction site (demolition earlier existing buildings, transfer engineering networks etc.), as well as additional costs arising from special conditions construction (in settlements remote from the existing infrastructure, as well as in cramped conditions for the production of work) should be taken into account additionally. 14. The standards do not take into account:

cutting and backfilling of soil during planning, dismantling and paving.
installation of additional structures when laying communication lines in existing collectors The cost of these works is normalized according to the relevant standards of the collections GESN-2001-1 " Excavation”, GESN-2001-27 “Roads”, GESNm-2001-10 Communication facilities

When laying communication networks in a trench, cable laying in a trench with a bed and an upper covering layer of loose earth is provided, as well as cable protection signal tape. The NCS indicators take into account the following depth of laying optical and electrical cables (armored and unarmored):

1.2 m - for the main cable communication line (MKLS), the main connecting cable communication line (MSKLS), optical cables on the intrazonal cable communication line (VZKLS) and on interstation connecting lines of the city telephone network (GTS);
0.8 m - for communication cables on local (urban and rural) primary networks

14. The laying of overhead communication lines is carried out on reinforced concrete supports, the height of the supports is 6.5 meters. The type of lines is assumed to be normal (H) with a distance between supports of 62.5 meters and the number of cables is 4. When laying a fiber-optic communication line along existing poles of 35-220 kV overhead lines, complicated working conditions were taken into account (cable suspension with an intersection with 35-220 kV overhead lines, with electrified and non-electrified public railways, with highways, communication lines, crossings over water barriers, swamps, clearings). 15. Enlarged estimated norms and prices for the installation of communication networks are differentiated depending on the method of laying (underground and overhead), as well as on the brand of cable. When laying networks in cramped conditions of a built-up part of the city, coefficients are applied to the indicators - 1.08 for underground laying, 1.02 for air. 16. The figures are given without value added tax. Calculation example: It is necessary to calculate the cost of building a city communication line with a length of 16 km, consisting of 5 sections.

1 section - 4.4 km in a trench;
Section 2 - crossing the motor road of category III using the horizontal puncture method (40m);
3 section - 8 km in the existing cable duct;
4 section - crossing under the railway tracks in the existing cable duct (60m);
5 section - 3.5 km in a trench, in cramped conditions in a built-up part of the city;

The cost of building a cable communication line is 27,754.15 thousand rubles. excluding value added tax.

In electrical work, a huge amount of cable products is used: wires and cables, as well as cable channels, corrugated pipes, trays and boxes used to protect them. Of course, the cable products themselves have the largest assortment: there are thousands of nomenclature items that differ in type, brand, cross section and purpose of the cable. In this essay, we, of course, will not be able to find prices for all types of cables and wires. Let's try to better consider the most popular types of cables most commonly used in cost estimates:

UTP twisted pair;

Fiber optic cable;

Optical cable (FOCL);

SIP wiring;

Overhead line wires and lightning protection cables;

Power cable type VVG (ng) (LS);

Control KSSP, KVVG;

Wire PV3 yellow-green for grounding.

The listed cables, especially power VVG, have many modifications that differ in cross section, number of cores, incombustibility, power, etc. Almost each of them can be laid in different ways: openly and hidden under wallpaper, in ceilings, trays, corrugated pipes, cable channels. To protect cables in places where they pass through walls, steel sleeves are often used, which are cut from pipes with a diameter of 20-50 mm. Many power cables adapted to environmental conditions can be laid in a trench on a sandy base or without it. The places where cables pass on the ground are often marked with signal tape. Consider the option estimating the installation of cables using the example of UTP and fiber optic cable (FOCL):

Price for Twisted pair UTP 5E outdoor (copper)	Twisted pair UTP 5E outdoor (copper)	1 m cable			0.00	35

Please note that in our example, the optical cable is laid along a cable, which is very typical for outdoor installation. Thus, we came across another type of cable laying, which can also be used in the preparation of estimates - this is cable wiring. Note that the work on setting up the laid lines of the fiber-optic cable is placed in the section of installation, and not commissioning, which, however, is very typical for part 10 "Communication networks". Here, installation prices often coexist with commissioning and configuration of devices, low-voltage networks, communication and telephony devices.

Another typical option that can be found in almost any estimate on electric installation work, is the laying of power wires in corrugated pipes.

TERm08-10-010-01	Corrugated PVC Pipe Laying for Wire and Cable Protection	100 m	112,02	40,77	0,1	426,28

TSSC-507-2838	Pipe clamps	1 PC.			0.00	7,4

Often the cable needs to be laid not in flexible corrugated pipes, but in stronger protective devices, such as trays or cable channels. For this, the TER territorial base has other rates. Laying cables and wires in trays is especially relevant for outdoor wiring. The following example of an estimate calculation just demonstrates the laying of cable products not inside the room, but from the outside (more precisely, at the point where the cables enter the building).

In the previous budgeting example, we installed an outdoor cable in a tray and brought it into the building, sealed it and connected it to devices in the right places. Now consider the option when the UTP cable, power VVG or control KVVG must be laid in the cable channel indoors. For this case, there are direct prices, both for laying the cable channel and for installing the wire itself. Let's look at an example below:

TERm08-02-398-02	Laying wire in trays, cross section up to 35 mm2	100 m	15,55	4,66	3,53	33,79

We looked at several examples of wiring, incl. in trays, boxes, corrugated pipes, on a cable, in a cable channel, as well as an external mounting method. I would like to dwell on the method of laying wires in a trench on a ready-made sand base. For these types of work there are direct prices from part 8 of the collection for installation electrical devices– they are easy to find in the collection. The only point is that these prices for laying wires in a trench are for power cables designed for higher voltage than most control and management cables. Therefore, it is not recommended to lay low-voltage cables along them, and for power ones, these prices will be just right. On this slightly optimistic note, I would like to end our short excursion into the industry estimated pricing in terms of laying cables VVG, UTP, SIP, PV3, KVVG and many of their analogues. By no means claiming to be the ultimate truth, we just tried to describe some of the most popular solutions when searching for prices on this topic. In general, as we have noticed, one of the features of using the TER, FER, GESN bases is the multivariance in the selection of prices for the same work (of course, in the absence of a direct price), so nothing prevents you from choosing one or another standard from the base yourself , and, perhaps, it will turn out to be more accurate and more appropriate than what we proposed. Thank you for your attention.
