Locally estimated calculation of the installation of the elevator. Preparation of local estimates for lift equipment

When a building requires the installation of an elevator, a local estimate is created that takes into account all the costs of materials, equipment, and work. Estimates for elevators should be developed in strict accordance with all standards. Failure to comply may result in a breach of safety requirements. A real professional should be engaged in the creation of estimates. We offer the services of the most experienced cost estimate engineers who will take on the most complex tasks.

In general, when estimators are faced with the task of drawing up a local estimate for the installation and operation of a freight or passenger elevator, they consider it an easy task. Indeed, what would seem easier: draw up an estimate for the installation and commissioning of elevator equipment when in any database there are prices for similar types of work. So, in the FER base, and in TERs, and, of course, in the GESN, there is a part of 3 collections for installation work, in which there are prices for marking the installation of many types of material handling equipment, incl. freight and passenger elevators. Part 3 "Handling equipment" contains a lot of prices: for the installation of conveyors, stacker cranes, bucket elevators, winches, etc., but now we are only interested in elevator equipment. Let's try to make an estimate for the installation of a passenger elevator in a multi-storey building at the prices of part 3.

An example of a local estimate for the installation of a passenger elevator

This example estimate considers the case of installing elevator equipment in a new apartment building without the need to dismantle the replacement elevator. A completely different situation in the preparation of estimates, when a passenger elevator is required to be installed to replace the existing one as part of a planned reconstruction and technical renovation. Then these prices will not work, and it will be necessary to estimate the replacement of elevator equipment according to the collection for repair and technical re-equipment in part 2 of the collections TERmr, (FERmr). Let's try to estimate the installation work for the same passenger elevator for 9 stops, only now with the dismantling of the old equipment.

An example of an estimate for the replacement of a passenger (freight) elevator in an apartment building

Drawing up an estimate for the installation and commissioning of a freight elevator has its own nuances related to the fact that a freight elevator has a greater carrying capacity than a passenger one. When installing a freight elevator, you can use the prices:

GESNm (FERm) 03-05-004-05 adjusted for the number of stops, shaft height, load capacity. Price - GESNm (FERm) 03-05-004-16 helps to balance the cost of a freight elevator in the presence of additional mine doors. For marking the dismantling of a freight elevator, the same prices can be used only with the correction factor for dismantling.

If you need to dismantle the old winch beams, you can use the price of GESNr (FERr) 54-8-1. It is necessary to make holes for the calling devices - then we will take the price from part 46 for the reconstruction of FER46-03-009-01.

In any case, if you need to make an estimate for the installation of a freight elevator, general construction work, dispatching or electrical work, our estimate bureau "SMETA-PROF" is always ready to do this work for a small fee.

Introduction

One of the most important problems of the modern market economy is the reproduction of fixed production assets, which are characterized by a high wear rate and a long service life. The physical and moral deterioration of elevator equipment makes it necessary to attract significant investments for the replacement and reconstruction of passenger elevators in office buildings and apartment buildings.

In market conditions, ensuring the competitiveness and survival of enterprises for the repair and production of passenger elevators is possible only by reducing the cost of products, works and services. The estimated cost of works on the modernization of elevators is much lower than the estimated cost of acquiring and installing new equipment. Therefore, in graduation theses in the specialty 13.02.11 - Technical operation and maintenance of electrical and electromechanical equipment (by industry), the main attention should be paid to a strict regime of saving material, labor and financial resources to justify the estimate of work on the modernization of elevators.

The calculation of the estimated cost of these works includes four types of calculations: general construction works, electrical installation works, commissioning works, calculation of equipment and materials not included in the price list.

In the economic part of the thesis in the specialty 13.02.11 - Technical operation and maintenance of electrical and electromechanical equipment (by industry), it is recommended to use the base-index method when compiling local estimates for the modernization of elevators. At the same time, the base prices as of 01.01.2001 are multiplied by the corresponding coefficients - indices, which are quarterly published in special economic journals, to bring them to the current level.

Calculation of the local estimate "Modernization of the elevator"

2.1 Methodology for calculating the local estimate "Modernization of the elevator"

The local estimate "Modernization of the elevator" includes three types of calculations - general construction work, electrical installation work, commissioning work, as well as the calculation of materials not included in the price tag.

All calculations are carried out by the basis-index method. Estimated cost is determined by using current indices in relation to the cost of work in the base period. Indices take into account price changes due to inflation, changes in supply and demand for resources, etc.

The table of local estimates "Modernization of the elevator" includes a "table header" and lines for the names of work and cost calculation (numbered).

We introduce separate designations of parameters in the columns of the table and formulas for calculations in each row of the table:

About to - the total amount of work (costs);

C 1 - cost (total) of a unit of work, rub.;

З 1н - the cost (total) of the basic salary per unit of work of workers not engaged in the operation of machines, rubles;

E 1 - the cost of operating machines when performing a unit of work (depreciation and wages of workers-machinists), rub.;

Z 1e - the cost of wages of workers-machinists engaged in the operation of machines when performing a unit of work - is included in the cost of operating machines when performing a unit of work, rub.;

M 1 - the cost of materials spent on the performance of a unit of work, rub.;

С about - the total cost of direct costs for the implementation of the total amount of work, rub.;

З he - the total cost of the basic salary of workers not machinists for the total amount of work, rubles;

E o - the total cost of operating machines when performing the total amount of work (depreciation and wages of workers-machinists), rub.;

M about - the total cost of materials spent on the implementation of the total amount of work, rub.;

З oe - the cost of wages of workers-machinists engaged in the operation of machines to perform the total number of works - is included in the cost of operating machines to perform the total number of works, rub.;

T 1n - labor costs (labor intensity of work) of workers not engaged in the operation of machines, per unit of measure of work, man-hours;

T he - labor costs (labor intensity) of workers not engaged in the operation of machines for the total amount of work, man-hours;

T 1e - labor costs (labor intensity) of workers-machinists engaged in the operation of machines, per unit of measure of work, man-hours;

T oe - labor costs (labor intensity) of workers-machinists engaged in the operation of machines for the total amount of work, man-hours.

The algorithm for calculating the local estimate for each item of work (each line) includes:

Name of work (from the bill of quantities), standard number (from reference books), units of work (from reference books).

About to - the total amount of work (from the bill of quantities);

T 1n - labor costs per unit of work of workers not engaged in the operation of machines (from reference books), man-hours;

T 1e - labor costs per unit of work of workers engaged in the operation of machines (from reference books), man-hours;

T total - total labor costs of workers by type of work, man-hours;

M 1 - the cost of materials spent on the performance of a unit of work (according to directories and price tags of materials), rubles;

E 1 - the cost of operating machines, including the salary of machinists, when performing a unit of work (according to directories), rub.

Direct costs C o, rub., include: wages of workers not engaged in the operation of machines, the cost of materials and equipment, the costs of operating machines and mechanisms, are calculated by the formula

C o \u003d Z he + E o + M o (1)

To calculate direct costs C o for each type of work, we use the following calculation algorithm:

1. The cost of the basic salary of workers not engaged in the operation of machines Z he, rubles, for the entire amount of work is calculated by the formula

Z he \u003d Z 1n × O to (2)

2. The cost of the salary of workers-machinists engaged in the operation of machines Z oe, rubles, for the entire amount of work, is calculated by the formula

Z oe \u003d Z 1e × O to (3)

3. The total cost of operating machines E o when performing the total amount of work, rubles, (depreciation and wages of workers-machinists) is calculated by the formula

E o \u003d E 1 × O to (4)

4. The total cost of materials M o, rubles, spent on the total amount of work, is calculated by the formula

M o \u003d M 1 × O to (5)

5. We determine the costs E o, rub., For the total amount of work according to the table, according to the formula

E o \u003d E 1 × O to (6)

6. We calculate the labor costs of workers who do not operate machines T he, man-hours, according to the formula

T he \u003d T 1n × O to (7)

7. We calculate the labor costs of workers operating machines T 1e, man-hours, according to the formula

T oe \u003d T 1e × O to (8)

8. The estimated cost of work C cm, rub., Included in local estimates consists of direct costs C o, overhead costs H o and estimated profit C p (planned savings), is calculated by the formula

The recalculation of the cost of costs, machinery and materials from the prices of the base period of January 2001 to the current period of January 2016 is carried out using the percentage price indices taken from the directory: cost index: for wages i s = 20.537; index for machines and mechanisms i e =12.159; index for materials i m =7.669, i total =10.705

10. Direct costs C o, rub., Taking into account price indexation, are determined by the formula

C o \u003d Z he + E o + M o (10)

11. Let's calculate overhead costs and estimated profit. Overhead costs N o, rub., are determined by the formula

N o \u003d Z he × P n / 100, (11)

where Z he is the wages of workers not engaged in service

P n - the percentage of overhead costs from wages,

take equal to 81%.

Estimated profit C p, rub., is determined by the formula

C p \u003d Z he × P pr / 100, (12)

where P pr is the percentage of the estimated profit, we take it equal to 51%.

According to formula (9), we find the estimated cost of work, which is included in the sections "General construction work", "Electrical work" and "Commissioning work" of the local estimate "Modernization of the elevator".

2.2 Calculation of the local estimate "Modernization of the elevator"

As an example, let's make a detailed calculation of the record "Electrical work" of the local estimate "Modernization of the elevator".

Code and position number of the standard - TERmr 308-03-545-01

Name of work and costs - Installation of a box (box) with clamps for cables and wires with a cross section of up to 6 mm 2 (on the wall or on the structure) floor.

Units of measurement - 1 pc.

We put it in the table - the total amount is O k \u003d 10.

According to the directories (TERmr for St. Petersburg), we take the cost of costs in prices as of 01/01/2001, as well as the labor intensity of the work:

The cost of the basic salary per unit of work, workers not engaged in the operation of machines, rub. Z 1n \u003d 3.46;

The cost of operating machines when performing a unit of work (depreciation and wages of workers-machinists), rub. E 1 = 2.85;

Including the cost of wages of workers-machinists engaged in the operation of machines when performing a unit of work, rub. Z 1e = 0.12;

The cost of materials per unit of work, rub. M 1 = 68.80;

Total cost of work per unit of work, rub. C 1 = 75.11;

Labor costs per unit of work of workers not engaged in the operation of machines (from reference books), man-hours; T 1n = 0.33;

Labor costs per unit of work of workers engaged in the operation of machines (from reference books), man-hours; T 1e = 0.11.

According to formula 2, we calculate the cost of the basic salary for the entire amount of work O to workers not engaged in the operation of machines,

Z he \u003d 3.46 × 10 \u003d 34.6 rubles.

According to formula 3, we calculate the cost of the salary of workers-machinists engaged in the operation of machines Z oe for the entire amount of work,

Z oe \u003d 0.12 × 10 \u003d 1.2 rubles.

According to formula 4, we calculate the total cost of operating machines E o for the entire scope of work (depreciation and wages of workers-machinists),

E o \u003d 2.85 × 10 \u003d 28.5 rubles.

According to formula 5, we calculate the total cost of materials M o spent on the performance of the total amount of work O k,

M o \u003d 68.80 × 10 \u003d 688 rubles.

We determine the costs E o for the total amount of work O k according to the table, according to formula 6,

E o \u003d 75.11 × 10 \u003d 751.10 rubles.

According to formula 7, we find the total amount of labor intensity for workers who are not engaged in the operation of machines,

T he \u003d 0.33 × 10 \u003d 3.3 people. h.

According to formula 8, we find the total labor input for the workers-machinists, i.e., those engaged in the operation of machines,

T oe \u003d 0.11 × 10 \u003d 1.1 people. h.

The results of the calculations are entered in columns 7, 8, 9, 10, and 12 of the local estimate.

Similarly, calculations are carried out for other types of work.

Received: C o \u003d 1309.62 rubles, Z he \u003d 50.12 rubles, E o \u003d 29.78 rubles, Z oe \u003d 1.68 rubles, M o \u003d 1229.44 rubles, T he \u003d 4.78 man-hours, Тoe = 0.14 man-hours

If work is carried out in cramped conditions, it is necessary to increase the value of wages, the cost of operating machines and the labor intensity of work by the constraint coefficient K 1 (from the reference book).

In our example, the constraint coefficient K 1 = 0.15.

We calculate the cost of the basic salary for the entire scope of work of workers who are not engaged in the operation of machines, taking into account the constraint coefficient,

Z he \u003d 50.12 × 1.15 \u003d 57.64 rubles.

We calculate the cost of operating machines E o for the entire scope of work (depreciation and wages of workers-machinists), taking into account the constraint coefficient,

E o \u003d 29.78 × 1.15 \u003d 34.25 rubles.

We calculate the cost of the salary of workers-machinists engaged in the operation of machines Z oe for the entire scope of work, taking into account the coefficient of constraint,

Z oe \u003d 1.68 × 1.15 \u003d 1.93 rubles.

We calculate the total labor intensity for electrical work of all workers, taking into account the constraint coefficient Ttot,

T total \u003d (4.78 + 0.14) × 1.15 \u003d 5.66 man.h

The recalculation of the cost of costs, machinery and materials from the prices of the base period of January 2001 to the current period of January 2016 is carried out using the percentage price indices taken from the directory: cost index: for wages i s =20.537; index for machines and mechanisms i e =12.159; index for materials i m =7.669.

We calculate the wages of workers for electrical work З he, taking into account the index i З

Z he \u003d 57.64 × 20.537 \u003d 1183.75 rubles.

We calculate the cost of operating machines and mechanisms E o, for electrical work, taking into account the index i e

E o \u003d 34.25 × 12.159 \u003d 416.45 rubles.

We calculate the total cost of materials M o, taking into account the index i m

M o \u003d 1229.44 × 7.669 \u003d 9428.58 rubles.

Total direct costs C o, taking into account price indexation are determined by the formula 10

C o \u003d 1183.75 + 416.45 + 9428.58 \u003d 11028.78 rubles.

Let's calculate the overhead costs H o, according to the formula (11). We take the percentage of overhead costs equal to 81%.

H o \u003d 1183.75 × (81/100) \u003d 958.84 rubles.

Estimated profit C p, is determined by the formula (12):

The percentage of estimated profit is taken equal to 51%

C p \u003d 1183.75 × (51/100) \u003d 603.71 rubles.

The total cost of electrical work C cm, we calculate according to the formula 9

C cm \u003d 11028.78 + 958.84 + 603.71 \u003d 12591.33 rubles.

All other types of work are calculated according to the same algorithm.

Today, elevators are available in almost all apartment buildings: it is convenient, practical, and fast. High-quality elevator equipment has been working properly for many years, but from time to time it is required to carry out scheduled maintenance, repair, or even a complete replacement of a freight or passenger elevator. And this, as you know, requires money, and not small ones. Often this requires draw up a correct cost estimate for work with elevator equipment at prices generally accepted in a particular region. For this purpose, territorial price bases have been created, called TER, for each region, region and edge of our vast country. Using these prices, estimators justify the cost of replacement, installation, maintenance and repair of elevator equipment, and, interestingly, the price for the regions for the same work does not always coincide. This is due to the regional industry and market conditions of individual territories and regions. In addition, differences in the cost of work with passenger and freight elevators arise when calculating the cost by the resource or base-index method. In our examples, we will try to consider examples of budgeting both in the GESN database and in unit prices TER / FER.

An example of budgeting for the replacement of elevator equipment

The specified cost estimate scheme in the TEP database is suitable for substantiating calculations for the element-by-element replacement of an elevator with dismantling in an existing apartment building. If there is a need to install new equipment without dismantling the old elevator, it is better to take other prices - from the collection for installation work. While in the previous example, the standards are set from the collection for maintenance and repair, that is, they are more suitable for work within the framework of reconstruction. Now let's look at an example in the FER database, more suitable for work within the framework of new construction.

An example estimate for the installation of new elevator equipment

The setting of prices for commissioning work on elevator equipment is carried out according to the prices of the FERp collection - Commissioning of Hoisting and Transport Equipment. Consider an example of drawing up an estimate for commissioning.

An example of an estimate for the commissioning of elevator equipment

When installing a new elevator or replacing an old one, it is mandatory to install and configure dispatching equipment: intercom sets, an elevator unit with an installation kit, as well as laying twisted-pair communication cables. We will not stop at the installation and commissioning of dispatching equipment. Let's just say that when drawing up an estimate, prices are taken from the assembly collection of communications. From the collection of instrumentation and automation, you can take the price FERm11-03-001-01, since it is universal and suitable for many types of devices installed on panels and consoles. You can start up a dispatcher connection at the rate FERp02-01-001-xx, the exact code is set depending on the number of channels.

Preparation of estimates for finishing work when replacing elevator equipment

A separate place in the preparation of estimates for the replacement of elevator equipment is occupied by general construction work. When dismantling the old and installing a new elevator in an apartment building, as a rule, it is necessary to repair the surfaces of walls, ceilings and floors in the machine room, elevator shaft and other utility rooms. In addition to the finishing itself, during the repair of the engine room, windows, doors and hatches are often changed. After laying communications, you need to close up the strobes, or, on the contrary, punch new holes for mounting calling devices on each floor. All these works can be attributed to general construction. Consider an approximate list of prices for general construction work during the reconstruction or replacement of an elevator:

Installation of fire doors: single-floor deaf Installation of fire hatches - FER09-04-013-01;

Dismantling of wooden fillings of openings: door and gate FER46-04-012-03;

Installation in residential and public buildings of window blocks made of PVC profiles: deaf with an opening area of ​​up to 2 m2 - FER10-01-034-01;

Device of couplers: cement 20 mm thick - FER11-01-011-01;

Simple oil painting of previously painted floors: with preparation and cleaning of old paint up to 35% FERr62-6-3;

Continuous leveling of wall plaster with cement-lime mortar with a thickness of the bast: up to 5 mm - FERr61-1-1;

Painting with water-based compositions of wall surfaces previously painted: water-based paint with cleaning of old paint up to 35% - FERr62-16-3;

Installation of rectilinear and curvilinear ladders, firemen with railings - FER09-03-029-01.

Drawing up estimates for electrical work during the installation of passenger and freight elevators

Well, here we come to the electrician - that, in fact, thanks to which the elevator travels at all. When installing a passenger elevator in an apartment building, fluorescent lamps are usually installed (for example, at the price of TERm08-03-593-06), switches and sockets (in the engine room), circuit breakers of the IEK type, switchboards ShchRN-12 (at the price of FERm08-03 -573-04), tires, YTP boxes, junction boxes and other electrical products. Almost all prices are taken from collection No. 8 for electrical work, which is quite natural.

Thus, we briefly talked about how to make an estimate for the replacement of elevator equipment (as part of a major overhaul or during new construction). For only one elevator equipment, you can make a lot of options for estimates, because there are freight elevators, passenger elevators, for office buildings, with microprocessor equipment for a different number of floors. In addition, an estimate can be drawn up for the dismantling of the elevator, for the installation of its individual elements or systems. In each case, the estimator individually approaches the calculation. We will make for you any estimated calculation for elevator equipment at the lowest price. Contact our estimate bureau for quality estimates at an affordable price.
