In accordance with the calendar plan for the production of works, a schedule was drawn up for the movement of the main construction machines around the facility. The need for construction machines and mechanisms is determined based on the scope of work. The number of machine shifts by months is distributed taking into account the duration of the mechanized process. The results of the calculation are given in table. 5.

Determination of the estimated number of workers at the construction site

The basis for determining the number of workers on the construction site is the maximum number of workers in the main production, employed in one shift. It is determined by the schedule of movement of workers:

Nmax main = 57 people

The number of workers in non-core production is assumed to be 20% of the number of workers hired according to the schedule. The data are summarized, and the result is used in further calculations:

Nmin. = 57 * 0.2 = 11 people

The number of engineering and technical workers (ITR) in one shift is taken in the amount of 11-14% of the total number of employees in the main and non-main production:

Nitr \u003d 68 * 0.12 \u003d 8 people.

The total estimated number of workers employed at the construction site per shift is determined as the sum of all categories of workers with a coefficient of 1.06 (of which 4% are workers on vacation and 2% are sick leave):

Ncalc. in 1 shift \u003d (57 + 11 + 8) * 1.06 \u003d 79 people.

The number of women is assumed to be approximately 20% of the total number of employees:

Composition and areas of temporary mobile buildings and structures

The composition and areas of temporary buildings and structures are determined at the time of the maximum turnaround of work at the construction site according to the estimated number of workers employed in one shift.

The type of temporary structure is accepted taking into account the period of its stay at the construction site: if the duration of the construction of the facility is 6-18 months - container-type buildings.

At a construction site with less than 60 people working in the most numerous shift, there must be at least the following sanitary facilities: dressing rooms with wash basins; showers; for drying and dedusting clothes; for heating, rest and eating; foreman; toilet.

With the number of employees up to 150 people, first-aid kits should be in the foremen.

The results of calculating the need for temporary mobile buildings are given in tabular form, see table. 6.

1 The need for construction workers

The largest number of workers at the construction site is determined according to the workforce movement schedule or on the basis of the work schedule, the volume of work performed and the average annual output of performers per worker according to the formula:

where BUT- the number of workers at the construction site;

B - total cost construction and installation or special works, 3960.0 thousand rubles;

AT- average annual output per worker - 15,000 rubles;

T- the duration of the work calendar plan, 3 years.

BUT= 3960000: 15000: 3 = 88 people

Engineers, employees and MOS make up 15% of the largest number of workers on the construction site:

BUT 1 = BUT´ 0.15 = 88 ´ 0.15 = 14 people

BUT 2 = BUT -BUT 1 \u003d 88 - 14 \u003d 74 people.

Workers in the most numerous shift make up 70% of the largest number of workers on the construction site:

A 3 = BUT 2 ´ 0.70 = 74 ´ 0.70 = 52 people

Engineers, employees and MOS in the most numerous shift make up 80% of the largest number of engineers, employees and MOS at the construction site:

BUT 4 = BUT 1 ´ 0.80 = 14 ´ 0.80 = 12 people

The total number of employees in the most numerous shift will be:

BUT 5 = A 3 + BUT 4 = 52 + 12 = 64 people

Working women in the most numerous shift make up 30% of the total number of employees in the most numerous shift:

BUT 6 = BUT 5 ´ 0.3 = 64 ´ 0.3 = 20 people

BUT 7 = BUT 5 - BUT 6 = 64 - 20 = 44 people

The number of employees employed in motor transport, in service enterprises and auxiliary industries (factories of reinforced concrete structures, concrete-mortar units) is not included in the calculation due to the centralized supply of concrete and mortar for construction, as well as semi-finished products and products from factories and bases of Glavmospromstroymaterialov by Glavmosavtotrans vehicles.

The basis for determining the number of workers on the construction site is the maximum number of workers in the main production, employed in one shift. It is determined by the schedule of movement of workers:

Nmax main = 57 people

The number of workers in non-core production is assumed to be 20% of the number of workers hired according to the schedule. The data are summarized, and the result is used in further calculations:

Nmin. = 57 * 0.2 = 11 people

The number of engineering and technical workers (ITR) in one shift is taken in the amount of 11-14% of the total number of employees in the main and non-main production:

Nitr \u003d 68 * 0.12 \u003d 8 people.

The total estimated number of workers employed at the construction site per shift is determined as the sum of all categories of workers with a coefficient of 1.06 (of which 4% are workers on vacation and 2% are sick leave):

Ncalc. in 1 shift \u003d (57 + 11 + 8) * 1.06 \u003d 79 people.

The total estimated number of workers employed at the construction site per shift is determined as the sum of all categories of workers with coefficients of 1.06 (of which 4% are employees on vacation, 2% are absenteeism due to illness).

5.2. Determination of the composition and area of ​​temporary buildings and structures.

The composition and areas of temporary buildings and structures are determined at the time of the maximum turnaround of work at the construction site according to the estimated number of workers employed in one shift.

The type of temporary structure is accepted taking into account the period of its stay at the construction site: during construction lasting up to six months, mobile temporary structures are used. The results of calculating the need for temporary mobile buildings are given in Table. 4.

At a construction site with less than 80 people working in the most numerous shift, there must be at least the following sanitary facilities: dressing rooms with wash basins; showers, medical center, for drying and dedusting clothes; for heating, rest and eating; foreman; toilet; women's personal hygiene.

5.3. Calculation of water demand for construction needs.



Temporary water supply at the construction site is intended to meet industrial, household needs and fire fighting. The required water flow (l / s) is determined by the formula:

Q \u003d P well +0.5 (R b + R pr),

where R b, R pr, R pzh - water consumption, respectively, for domestic, industrial needs and for firefighting, l / s. Water consumption for domestic needs is made up of:

R 1 b - water consumption for washing, eating and other household needs;

R 2 b - water consumption for taking a shower. Water consumption for domestic needs is determined by the formulas:

R 1 b \u003d N * b * K 1 / 8 * 3600, R 2 b \u003d N * a * K 2 / t * 3600,

where N is the estimated number of personnel per shift;

b - the rate of water consumption per 1 person per shift (in the absence of sewerage, 10-15 liters are taken, in the presence of sewerage, 20-25 liters);

a - water consumption rate per person using a shower (in the absence of sewerage - 30 - 40 l, in the presence of sewerage - 80 l);

K 1 - coefficient of uneven water consumption (taken in the amount of 1.2-1.3);

K 2 - coefficient taking into account the number of washers - from the largest number of workers per shift (taken in the amount of 0.3 - 0.4);

8 - the number of hours of work per shift;

t is the operating time of the shower installation in hours (assume 0.75 h).

P 1 b \u003d 78 * 20 * 1.2 / 8 * 3600 \u003d 0.029 l / s;

P 2 b \u003d 78 * 80 * 0.3 / 0.75 * 3600 \u003d 0.31 l / s;

R b \u003d R 1 b + R 2 b \u003d 0.029 + 0.31 \u003d 0.339 l / s.

Water consumption for production needs is determined by the formula:

R pr \u003d 1.2 * K 3 ∑q / n * 3600

where 1.2 is the coefficient for unaccounted for water costs;

Kz - coefficient of non-uniformity of water consumption (assumed to be 1.3-1.5);



n is the number of hours of work per shift;

q - total water consumption per shift in liters for all production needs that do not coincide with the time of work (according to the work schedule).

R pr \u003d 1.2 * 1.3 * 800000 / 8 * 3600 \u003d 43.3

Water consumption for fire extinguishing is determined depending on the area of ​​the site, taken according to the construction plan, equal to 10 l / s.

Required water flow

Q= 10+0.5(0.339+43.3)=31.81 l/s

Based on the calculations, the diameter of the pipeline is determined by the formula:

D=(4*Q*1000/πv) 1/2

where Q is the total water consumption for domestic, industrial and fire-fighting needs, l / s;

v is the speed of water movement through the pipeline, m/s (we take v=2 m/s).

D \u003d (4 * 31.81 * 1000 / 3.14 * 2) 1/2 \u003d 142.34 mm.

Estimated diameter of the pipeline is 142.34 mm. The diameter of the water supply network is assumed to be 150 mm. (V=1.39; 1000i=23.3)

5.4. Calculation of the required electricity and selection of the required power of transformers.

Electricity in construction is spent on power consumers, technological processes, indoor lighting of temporary buildings, outdoor lighting of work sites, warehouses, access roads and construction areas. The calculation of the need for electrical energy is given in Table. 5.

Table 5:

The required electricity and power of the transformer are calculated by the formula:

P trans \u003d a * (K 1 ∑ P with / cosφ 1 + K 2 * ∑ P mech / cos φ 2 + K 3 * ∑ R v.o. + K 4 * ∑ R n. o.)

where a is a coefficient that takes into account losses in the network; depending on the

network length, a=1. 05-1.1;

∑R s - the sum of the rated powers of all power plants, kW;

∑P mech - the sum of the rated powers of the devices involved in the technological processes, kW;

∑P v.o. - total power of interior lighting fixtures, kW;

∑Р but - the total power of outdoor lighting fixtures, kW;

cosφ 1 , cosφ 2 - respectively, power factors depending on the load, power and technological needs; accepted respectively: 0.6 and 0.75;

K 1, K 2, Kz, K 4 - respectively, the survey coefficients, taking into account

mismatch of loads of consumers and accepted: K 1 =0.5, K 2 =0.7, Kz=0.8, K 4 =1.0.

P trans \u003d 1.1 * (0.5 * 72 / 0.6 + 0, 7 * 70 / 0.75 + 0, 8 * 0.9 + 1.0 * 4) \u003d 1 43 kW

In accordance with the obtained power value, we select a transformer. We choose a complete mobile transformer substation KTPP-58-320

5.5. Calculation of the need for compressed air.

Compressed air at the construction site is necessary to ensure the operation of devices (including jackhammers, perforators, pneumatic rammers, hand-held pneumatic tools for cleaning the surface from dust, etc.)

Compressed air sources are stationary compressor stations, and most often mobile ones. compressor units. The calculation of the need for compressed air is made from the operating conditions of the minimum number of devices connected to one compressor. The power of the required compressor unit is calculated by the formula:

where 1.3 - coefficient taking into account network losses;

∑q- total air consumption by devices, m3/min;

K - the coefficient of simultaneity of the operation of the devices, taken during the operation of 6 devices - 0.8.

Q \u003d 1.3 * 0.8 * 12.4 \u003d 12.9 m 3 / min

The capacity of the receiver is determined by the formula:

V \u003d K √ Q \u003d 0.4 * √ 2.9 \u003d 1.44 m 3

where K is a coefficient depending on the compressor power and taken for mobile compressors - 0.4;

Q - power of the compressor unit, m 3 / min. We accept PKS-5 compressor units (selection according to the reference book), in the amount of 3 pieces. The diameter of the distributing pipeline is determined by the formula:

D = 3.18√Q=3.18*√12.9=11.4mm

where Q is the calculated air flow, m 3 / min.

The resulting value is rounded to the nearest standard diameter, and 15 mm is selected.

5.6. Determining the need for oxygen.

4400 m 3 - for the oxygen demand of housing and communal services. In one cylinder (40 l.) - 6.0 m 3 oxygen. 734 cylinders are needed.

8.7 Calculation of heat demand.

At construction sites, heat is consumed for heating buildings and greenhouses, for technological needs (for example, steaming reinforced concrete structures in winter time, steam heating of frozen soils, etc.)

Heat consumption for heating temporary buildings

Q \u003d qV (t in -t n) * a,

Q 1 \u003d 0.45 * 13827.04 * (22-(-9)) * 0.9 \u003d 173.598 * 10 3 kJ

Q 2 \u003d 0.8 * 549 * (22-(-9)) * 0.9 \u003d 51.46 * 10 3 kJ.

where q is the specific thermal characteristic of the building; kcal / m 3. .h.grad.

for temporary buildings it is taken equal to 0.8 kcal / m 3 .h.g.;

for capital residential and public buildings taken equal to 0.45 kcal / m 3 .h.grad.;

a- coefficient taking into account the influence of the calculated outdoor temperature on q (1.45-0.9)

V- volume of the building in terms of external volume, m 3

t in - calculated internal temperature

t n - calculated outdoor temperature

Heat consumption for technological goals is determined each time by special calculations, based on the given volumes of work, the period of work, the adopted modes or by the specific heat consumption per unit volume or product according to the available reference data.

The total amount of heat is determined by summing up the heat costs for individual needs, taking into account the inevitable heat losses in the network in kcal and converted to kJ (1kcal-4.2kJ):

Q total \u003d (Q 1 + Q 2) * K 1 * K 2,

Q total \u003d (173.598 * 10 3 + 51.46 * 10 3) * 1.5 * 1.1 \u003d 371.346 * 10 3 kJ.

Where Q 1 is the amount of heat for heating buildings and greenhouses, kcal / h.

Q 1 - the same, for technical needs;

K 1 - coefficient taking into account heat losses in the network (approximately, you can take K = 1.15);

K 2 - coefficient providing for an addition to unaccounted for heat costs, taken as K = 1.10.

8.8 Calculation of the need for storage space.

A set of issues related to the organization of warehouse management includes the determination of stocks of materials and the calculation of the area of ​​​​warehouses.

Stocks of materials

Where Q is the amount of material required to perform this type of work;

T is the estimated duration of the work, days;

n - material stock rate (when transporting material by road, it is taken equal to 2-5 days);

K - coefficient taking into account uneven supply, taken equal to 1.2.

P 1 \u003d (1597.1 / 64) * 3 * 1.2 \u003d 89

The required warehouse area is determined based on the expression:

S=(P/r*KII)*n*K,

Where P is the amount of material to be stored;

r is the rate of storage of material per 1 m 2 of area;

K II - coefficient taking into account passes.

S \u003d (27 / 6 * 0.5) * 3 * 1.2 \u003d 32.4 m 2

A COMMON PART

A COMMON PART

The standard structure and norms for the number of engineering and technical workers and employees are intended for use in construction and installation and repair and construction departments and self-supporting sections of the industry.

The development of a typical structure and population standards is based on:

guidelines and provisions for the development of normative materials of the Research Institute of Labor;

the results of the analysis of technical and economic indicators and the state of labor organization and production management of construction and installation and repair and construction organizations;

technical calculations using methods of mathematical statistics;

collection "Typical structure and standards for the number of engineers and employees of construction and installation and repair and construction organizations of the oil industry". - M., VNIIOENG, 1978.

The standard structure and norms for the number of employees are established for the administrative apparatus and production units of construction and installation and repair and construction departments and self-supporting sections.

The headcount standards are calculated by establishing its relationship from the main norm-forming factors for the following management functions, arising from the content and nature of the work performed by engineering and technical workers and employees of the construction and installation and repair and construction departments.

I. General guidance

II. Production and technical.

III. Occupational health and safety.

IV. Repair and energy service.

V. Technical and economic planning.

VI. Organization of labor and wages.

VII. Accounting and financial activity.

VIII. Logistics.

IX. Selection, placement and training of personnel.

X. Paperwork and economic services.

XI. Design and organizational (design and estimate) work.

Standards for the number of production (line) personnel of industrial construction sites, civil engineering, electrical work, auxiliary production, etc. are presented by the total number for each division, depending on the indicators of the work performed.

The standards for the number of engineers and employees of the administrative apparatus (N) are determined separately for each function, depending on the following norm-forming factors:

The annual volume of work performed on its own, taking into account the correction factors for the types of work provided for by the Decree of the USSR State Committee for Labor and the Secretariat of the All-Union Central Council of Trade Unions of March 16, 1971 N 88/8 to classify organizations as a group for remuneration of managers and engineering and technical workers. The scope of work excludes amounts attributable to regional coefficients to wages, northern allowances and costs for procurement and storage work, million rubles;

- the annual volume of work under the general contract (management or self-supporting site), taking into account the adjustment coefficients for the types of work, minus the volumes attributable to regional wage coefficients, northern allowances and costs for procurement and storage work, million rubles.

If the SMU (RCS) does not perform work under the general contract, then the factor is taken.

- the annual volume of work of the section, performed on its own, taking into account the correction factors for the types of work, minus the volumes attributable to regional wage coefficients, northern allowances and costs for procurement and storage work, million rubles;

- the cost of machines and mechanisms on the management balance sheet, thousand rubles;

- total number of employees in the department, people;

- the number of workers in management, people;

- number of workers in the area, people;

- number of plots under management, units.

The normative number is determined by the formulas. When a fractional value is obtained, values ​​of 0.5 or more are rounded up to an integer, and less than 0.5 are discarded.

The normative headcount in general for management (SMU, DCS, SU, etc.) is determined by summing up the corresponding normative values ​​for the functions of management and production sites, calculated for the planned volumes of work.

If individual indicators are not planned, their actual values ​​for the year are taken.

The number of employees involved in the performance of the functions of labor regulation and accounting in production units (sections) is provided for by the standards for the number of administrative staff.

If in control as a result high level organization of labor and production management, the implementation of the production plan is carried out by a smaller number of engineering and technical workers and employees than provided for by these standards, the number should not increase.

The standard structure and standards do not provide for the number of road construction (road repair) departments and road sections that are part of the construction and installation and repair and construction departments, as well as mechanized works departments.

The regulations do not cover the following structural units, groups and positions that are part of the construction and installation and repair and construction departments: security personnel, housing, convoy (garage), gamma-ray flaw detection laboratories, industrial gymnastics instructors, civil defense workers, office cleaners, couriers.

The number of sentry guards is established within the approved labor limits for this category of workers. The number of personnel of communication centers is established depending on the availability of communication facilities (commutator, teletype, walkie-talkie) within the labor plan. The number of civil defense workers is determined on the basis of the relevant Regulations, and instructors-methodologists of industrial gymnastics - in accordance with the decision of the Presidium of the All-Union Central Council of Trade Unions of April 22, 1956.

The names of positions in the collection are established in accordance with the current directories: "Qualification directory of positions of employees." - M .: Research Institute of Labor, 1979 and current schemes official salaries provided for by the Decree of the Central Committee of the CPSU, the Council of Ministers of the USSR and the All-Union Central Council of Trade Unions of December 29, 1968 N 1045.
