5. ECONOMY OF CONSTRUCTION.

5.1. Marketing research

In marketing research necessity of construction of the given lyceum for the chosen area of construction, the social importance is proved and the source of financing of construction is underlined.

Necessity of construction is connected to the new program of education of the government of Russia. The concept of education assumes cardinal change of the contents and methods of training at all three steps of the common education. Its realization solves the following problems:

ü     Enables to increase comfort of the material environment initial and in part the basic of schools according to new social - pedagogical requirements.

ü     Causes preconditions for creation of base differentiation profile training, equipment by material resources, attraction to training highly more skilled teachers;

ü     Predetermines more economical decision of a way of construction of new schools due to the system approach.

ü     Increase of a qualitative educational level.

ü     Creation of the interesting psychological environment (' the environment brings up ').

ü     Improvement of conditions of an air inhabitancy due to increase of specific volume and frequency rate of an exchange of air, and also air aeration.

Above-mentioned positions also are a substantiation of necessity of construction of lyceum in Mokrous Fyodorovskaya area of the Saratov area. The basis for designing and construction of a new building of lyceum is the decision of administration Fyodorovskaya of area and task A (Central administrative board of Committee of Construction) of the Ministry of construction of the Government of the Saratov area. Construction of object will be financed due to means of the local and regional budget.

But for the given area of construction it is more expedient to include in its structure an elementary school, with preservation of prevailing quantity(amount) of learning senior classes. In that case the parity (ratio) of parallels of educational classes is accepted 1:2:2.

Lyceum in Mokrous is the multipurpose center. According to positions A 4.06-96' General educational establishments ' [1] and the 2.4.2.782-99 'School establishments' [3] building is projected for service of pupils and the population in no learning time. Use of rooms by the population (except for educational) is provided at o'clock when schoolboys according to an educational mode of day will not be in lyceum. To such rooms in a projected building of lyceum concern: 2 sport halls, an assembly hall, a video-hall, a photo laboratory, library, and a dining room. The specified rooms are projected in view of their use by administration of lyceum in commercial objectives in free time from study and in days off.

6. SAFETY OF TECHNOLOGICAL PROCESS.

6.1. The analysis of dangerous and harmful production factors.

The major tasks of a labor safety in construction are the prevention of failures and reduction of dangers, which can arise during erection of object. Process of erection of a building of lyceum is subdivided into a number (line) of civil works which estimation of dangers is resulted in the given section.

The analysis of the reasons of cases of a heavy traumatism speaks about imperfection of technology of separate working processes.

6.2. Industrial sanitary.

Industrial sanitary includes a complex of organizational, hygienic, sanitary and technical actions and the means preventing influence on people of harmful production factors.

In order to prevent consequences of action of harmful factors on workers maintenance with individual means of protection - overalls, footwear, a welding mask, a respirator, rubber ia is stipulated, rubber gloves etc. pass Workers obligatory preliminary and periodic medical surveys. At the organization of building manufacture of workers provide with household rooms. The question of the organization of sanitary - consumer services of workers is considered in section 'Organization of construction'.

6.3. Ergonomics.

The ergonomics study functionalities of the person during activity with the purpose of creation and maintenance of such conditions, which make this activity more effectively and provide comfort for the person.

The processes demanding the maximal compatibility of system 'person - engineering' is a management of the assembly crane, a dredge.

6.4. The safety precautions.

Danger - the complex (difficult) process promoting in certain conditions to damage human, material, natural resources.

For definition of danger and development of no production decisions on its reduction make decomposition of considered (examined) process. Decomposition provides division of system into elements and definition of danger from each element, and their dangerous combinations to provide effective actions for decrease (reduction) of these dangers.

6.5. Fire safety.

Fire-prevention requirements by development of the general plan and iaa, the analysis of explosive and fire danger of used substances and materials, definition of a degree of fire resistance of a building and separate designs, fire prevention rules at performance are developed on the basis of the normative documentation and considered in sections: 'Architectural - building' and 'Organization of construction '.

6.6. Protection of an environment.

At a stage of construction of action for protection of atmospheric air, water resources, ground resources, from influence of noise are developed in sections: 'Ecology' and 'Organization of construction'.

At a stage of operation of object: the harm, selected with the process equipment established in lyceum, does not exceed norms of maximum concentration limit.

Ways of migration of animals through a site of lyceum are not present, aa minerals on a borrowed (an occupied) platform it is not revealed.

6.7. Forecasting extreme situations and liquidation of their consequences in area of object.

The Saratov area concerns to territory on which the dangerous natural phenomena and aiaaa failures for the various reasons take place. Such extreme situations can be large industrial failures and fires with emission of dangerous chemical substances; flooding; failures on railways and motorways etc.

The projected building of lyceum is located in 0,6 km from the railway which is chemically dangerous object. Therefore at failure by the railway, the lyceum can appear in a zone of the center of mass defeat. The most widespread transported dangerous substance is ammonia. It is supposed, that as a result of failure can take place self-untight 2 tanks with ammonia (120 tons).

As a result of calculation and forecasting of an extreme situation the conclusion consists that because of the fast approach of a cloud of ammonia to object (12 mines) evacuation of people from a building motor transport in safe areas is not possible. As duration of amazing action is not great (1 . 42 minutes) ia ammonia the building of lyceum is capable to provide protection of people against a cloud. In case of failure and emission of ammonia evacuation of all people that are taking place in a building, is provided in premises of a cellar. Total the person - 619, the free area of a cellar makes 1396,99 m2 (2,26 m2 on the person). In these rooms are placed additional furniture for time stay of people (chairs, benches), the separate room of storage of means of an individual defense, means of first-aid treatment is provided; bathrooms.

For decrease(reduction) of consequences of failure it is provided:

1)     Creation in Mokrous dispatching service with the automatic monitoring system of chemical infection and the notification of the population about chemical danger.

2)     in each class, a study the place of storage of means of an individual defense in necessary quantity(amount) is organized. These are small-sized gas masks A-5 and A-7 complete with additional cartridges for protection of bodies of breath against ammonia.

3)     Accommodation inside a building (in corridors, on staircases) marks and indexes of ways of evacuation.

4)     Presence of decontaminating substances (for ammonia - water).

5)     The device of system of automatic dispersion of water around of a site of lyceum for creation of a water veil.

6)     Realization of regular training employment(occupations) for pupils, teachers etc. workers of lyceum on use of means of an individual defense, rendering of the first medical aid.

7)     In a medical study the stock of antipillboxes for ammonia - formaldehyde is provided; 5 % of a solution acetic (or citric) acids; 3 % of a solution of a boric acid for processing a skin and mucous membranes; 30 % of a solution of albucid for processing eyes; gauze bandages etc. means.

7. Ecology.

The ecological control puts the tasks: supervision over a condition of environmental natural environment and its change under influence of economic and other activity; check of performance of plans and actions for wildlife management, rational use of natural resources, improvement of environmental natural environment, observance of requirements iiiaiai legislations and specifications of quality of environmental natural environment. Preservation of the environment is carried out by realization of precautionary and active actions. To the first for maintenance and preservation of natural balance, and creation of conditions concerns to the second - purposeful activity on protection and preservation of the natural environment by development of technical and organizational actions for elimination of air pollution, reservoirs and ia, protection of a wood and vegetative plantings (spreading).

7.1. Possible (probable) kinds of influence on an environment.

7.1.1. Entering polluting substances in an environment.

1)     The atmosphere - becomes soiled harmful substances as a result of increase of a level of a gassed condition at burning waste products of building materials; as a result of open storage of raised dust materials; as a result of development and transportation of a ground, operation of roads a covering on a building site; as a result of manufacture of paint and varnish and welding works.

2)     The ground - becomes soiled and collapses a superficial layer, the vegetative cover is damaged, hydro-geological conditions of a platform, and also absence of the specialized water-shower points engineering are broken result in pollution of ground, subsoil waters by combustive-lubricating materials. At work of building engineering there can be an additional condensation of a ground.

3)     The hydrosphere - becomes soiled due to dump of sewage on a surface of a site, education of dumps of inorganic dust. Pollution of the petroleum products and waste products of construction of superficial and underground waters.

4)     Noise pollution - occurs as a result of work of building engineering, a bad condition of access roads and roads. The significant level of noise and vibrations on a building site create the following processes: condensation of a concrete mix by vibrators, piles a diesel engine - ii, drilling leader chinks chisel installation, cutting down of concrete from skeletons of piles jackhammers and work of compressor installation, and also work of dredges and bulldozers.

7.1.2. Withdrawal from an environment.

During manufacture of civil and erection works there is a consumption of water for various needs; air as a result of work of engines of machines, gas-flame torches of anticorrosive installations; ground resources - export of a ground from a building site.

1)     The ground - occurs the mechanized destruction of ground on all building site. The territory borrowed with a building (the area of building) is forever withdrawn from further use. By development of a foundation ditch natural addition of a ground is broken, occurs iaa a superficial layer. The water mode of territory changes, thus downturn of a level of subsoil waters that entails infringement of vegetation of plants is possible.

2)     Water resources - a plenty of water is consumed at conducting civil and erection works, on additional actions for service of construction and maintenance of necessary conditions of ability to live of workers.

3)     The atmosphere - occurs consumption of oxygen of air at combustion of fuel in engines of machines, use of an open flame of gas torches etc.

The most significant negative influence on an environment renders accumulation of waste products of building and household dust by manufacture of works. Therefore in section of ecology it is settled an invoice quantities (amounts) of the dust formed during construction. As a result of building manufacture on a building site the following waste products are formed: dust building, a breakage and waste products of ferrous metals; a ground which is taken out from a building site, dust household.

Limit of accommodation of waste products:

The waste products formed at places of manufacture of works weekly are taken out on the place of constant accumulation coordinated with the central State Sanitary Epidemiological Supervision.

. At gathering, transportation and storage of waste products safety precautions regulations are observed at realization of cargo handling works, thus pollution of an atmosphere is excluded.

        The project provides accommodation of waste products of construction:

        The building dust is taken out on a dump;

        The breakage and waste products of metal are taken out on the enterprises of acceptance of scrap metal;

        The ground developed during excavations, is taken out in career;

        The household dust is in part taken out on a dump, in part - is dumped (reset) in the water drain.

7.2. Recommendations for decrease of influence on an environment.

Influence on an environment during construction has temporary character. At the organization of building manufacture with a view of reduction of environmental contamination according to the project realization of the following actions is provided:

1.     At excavations in order to prevent pollution of atmospheric air by an inorganic dust humidifying a ground is provided.

2.     By manufacture of welding works in an atmosphere are allocated i iron, manganese and its connections, fluoric hydrogen, but the volume of welding works is not great and at their performance according to technology and observance of the safety precautions of especial actions it is not provided.

3.     Building - road machines are equipped with the special devices, capable to decontaminate emissions of toxic substances (i nitrogen, i carbon, hydrocarbon, soot). With the purpose of reduction of capacity of emission of pollution in an atmosphere, the works connected to emission will be carried spent not simultaneously.

4.     For reduction of noise by exhaust pipes of machines mufflers are established.

5.     Application of the electric power for technological needs of construction instead of burning firm and liquid fuel.

6.     The closed storage, loading, an overload and transportation of loose materials, application of containers of special vehicles.

7.     Application of tight capacities for transportation of concrete.

8.     Receipt of emergency emissions is excluded. The building processes conducting to such emissions are not applied.

At cleaning waste products and dust the closed trays and bunkers - stores are applied. Export of building dust is carried out on the territory coordinated with the central State Sanitary-and-epidemiological Supervision - SSES (A).

The building of lyceum is under construction on a free site from building Mokrous in which there are no sources pollutions from which the device of a sanitary - protective zone is required. The object of construction on an environment of harmful influence while in service does not render.

The common fencing, bushes change in other zone, protects the green plantings spreading that are not subject to cutting down.

The fertile layer of ground on a site under construction of a building of lyceum and other constructions prior to the beginning of the basic excavations is removed and moves in ia for subsequent its use at recultivation.

On end of construction according to the project the accomplishment of territory with restoration of a vegetative cover and landing of green plantings is carried out.


THE CONCLUSION.

As a result of realization of the accepted design decisions normal sanitary-and-hygienic conditions of operation of a building, work and a life of the population living in area of construction of lyceum are provided. Negative influence of a projected building of lyceum on an environment is minimally. The decisions accepted in the project meet to ecological requirements, norms and rules of design stages, constructions and stages of operation.

All engineering decisions in the given project provide safe conducting civil and erection works and operation of object.

Application of the technological, ii-transport equipment with the device of safety and protective adaptations, blocking, systems of automatic protective switching-off, mechanisms with remote control, manufacture of works according to technology promotes reduction of accidents by manufacture.

The device of illumination of a platform, the equipment of sanitary - household rooms promotes the common improvement of working conditions and creation of comfortable conditions. Realization of the accepted decisions on a labor safety, the safety precautions allows lowering an industrial traumatism, professional and general diseases of workers.

Use of overalls, special footwear, means of an individual defense allows reducing to a minimum influence on an organism of working harmful production factors.

At a stage of operation of object safety is caused by correct operation of the technological and power installations equipped with means of automatic switching-off at infringement of a normal mode of operation.
