Any construction, especially in the city, poses a direct threat to the safety of citizens. This is due to the fact that the facilities use oversized equipment and materials that can fall. Therefore, fencing of the construction site must be installed for the entire period of work. Requirements for such facilities are defined in standards and regulations. Let's consider these constructions in more detail.

General rules

The organization of the construction site and its individual sections must ensure safe working conditions and proper sanitary and hygienic service, exclude and prevent possible threats. When carrying out activities at the facility, it is the responsibility of the customer to provide the contractor with a scope of work and carry out labor protection measures. The latter, in particular, include the fencing of the construction site.

Providing security

In the process of performing work related to the organization of a construction site in conditionsreconstruction, the following generally accepted measures must be taken:

1. Determining the boundaries of hazardous areas.
2. Fencing the construction site and its individual sections.
3. Providing the necessary lighting, driveways, walkways. For its organization, a separate electrical wiring is allocated. It should not be connected to the power grid of the object being reconstructed.
4. Organization of passageways for installation equipment and transport, passageways for workers, places for storing materials and structures.
5. Equipment of objects with primary extinguishing agents.
6. Ensuring electrical safety, compliance with sanitary and hygienic standards in the manner specified for the enterprise.
7. Installing safety signs.

GOST 23407.78: inventory fences for construction sites

To prevent unauthorized access by outsiders, protective structures must be installed around the facility. Inventory fences of construction sites adjacent to areas of mass passage of citizens must be equipped with protective corridors and canopies. At the reconstructed facilities, structures are used that ensure the safety of work and the continuity of the enterprise. In particular, the following are being built:

1. Temporary partitions and walls. They provide separation of workplaces and areas for the implementation of installation activities.
2. Protective floorings. They are used to prevent falling materials and objects in rooms whereproduction.
3. Coatings to protect against cold and precipitation.
4. Temporary fencing of the construction site, warning about the boundaries of territories and sites where construction and installation work is being carried out.
5. Structures preventing workers from falling from height.
6. Other fences, light shelters, screens. They are used to provide protection against blinding in the process of electric welding, thermal exposure, protection of glass from destruction during explosive events, to prevent contamination of equipment in the workshops of the enterprise.

Production of construction site fencing is carried out for specific conditions. Their design should be intended for reusable use. Any temporary construction site fencing must be easy to transport, reliable, durable, effective both day and night.

Additional rules

Outputs and entrances of the operated structure must be arranged outside the boundaries of hazardous areas. At the entrance to the construction site, a scheme for the movement of vehicles is established. Roadsides of driveways and roads are equipped with clearly visible signs regulating the traffic order. Builders must be provided with sanitary facilities in accordance with applicable regulations. At objects classified as explosive and fire hazardous, it is allowed to carry out work only with the permission of the responsible person appointed by the customer, in agreement with the gas rescue and fire services. In progressinstallation activities in gassed rooms, as well as in areas that are located below the floor / ground level, air analysis is carried out daily before the start of the shift.

Storage of materials and structures

It must be carried out in accordance with the provisions that contain technical documents and GOST. Construction site fencing is provided in such a way that when loading / unloading materials and structures with the help of special equipment, complete safety of workers is ensured. Places of storage are determined and coordinated with the management of the enterprise. Separate structures and stacks are arranged so that they do not block access to the viewing units of existing utility networks. Their placement on roads, crane and railway tracks is not allowed. When storing on bulk soils, measures are taken to eliminate the possibility of collapse of structures.

Loading, unloading and transportation

When performing these works, it is necessary to comply with the relevant provisions of SNiP, state standards and DNAOP. When loading, unloading and transporting using cars or trains, you should follow the traffic rules and the standards defined in the relevant documents. The speed of movement of vehicles on the territory of the reconstructed facility on straight and fairly well-visible sections cannot be higher than 10 km/h. At exits, including from a side passage to the main passage ora road with heavy traffic, entrances, inside workshops, at U-turns, intersections, when reversing, in dense fog, it should not exceed 5 km / h. When transporting structures in cramped conditions and with limited travel dimensions, red flags are fixed on parts that protrude beyond the dimensions of the vehicle, and when visibility is less than 20 m and in the dark, reflective devices.

Construction site fencing

SNiP is one of the key documents that establish the rules for ensuring security at facilities. The standards were adopted back in Soviet times. Taking into account the development of technology, they have been adapted to modern conditions. In 1979, GOST "Inventory fencing for construction sites" was approved and put into effect. In accordance with these documents, it is not allowed to carry out construction and installation works at the facility or its part without the installation of special protective structures.

Key prescriptions

Fencing of the construction site must comply with state-approved samples. The design should include wickets or gates to ensure the free movement of workers and vehicles. The construction site fencing must be collapsible with parts, fasteners and other elements of the same sample. The height of the racks, structures, the angle of inclination of the canopies, etc., must comply with the established parameters. The panels are made in the form of a rectangle. Their length, as well as the gaps between the uprights, are determinedaccording to the norms: from 1, 2 to 2 m and not more than 6 m, respectively. Between the parts it is necessary to observe a degree of rarefaction of 80-100 mm. An exception is the mesh for fencing construction sites. There should be no gaps in the flooring on the sidewalk exceeding 5 mm. Protective visors must be deployed in the desired direction. At the same time, they should cover people moving under them with a margin.

For the passage of citizens on the sidewalk, it is necessary to allocate more than 1.2 m. The railing must be attached to the visor or to the upper border of the fence. In addition, protective strips are provided at a height of 50 cm and 1.1 m from the roadway. Site fencing should be designed so that it can be repaired and removed while maintaining adequate strength. Responsible persons are obliged to take measures to prevent rotting and the spread of rust through the elements. The presence of a slope on the ground should not threaten the protective fence. The design must be coated with an appropriate coloring composition. It should be free of potentially traumatic elements (hooks, corners, and so on).

Fencing of the construction site is made of reliable materials that ensure its stability. The design must withstand falling objects of a certain weight, but not less than 200 kg / cm2, as well as the force of a gust of wind and the weight of snow. The materials from which the fence is made must have quality certificates and meet the established requirements. The service life of the structure is at least 10 years. For paving deck panels, this periodmust be at least 5 years old.

Classification of structures

Fences for construction sites are divided into types depending on their purpose. There are the following types:

1. Signal, unequivocally and clearly indicating that construction works are being carried out on the territory.
2. Protective, ensuring the safety of people from injury.
3. Security, preventing unauthorized entry of outsiders to the object.

Depending on their characteristics, fences are divided into the following types:

1. Rackmount.
2. Panel. They, in turn, are divided into sparse (grid, for example) and solid.
3. Combined.

Goals

The main task of security structures is to prevent people from entering the facility. In this regard, in most cases, they are not much different from simple fences installed around industrial facilities or residential buildings. Protective structures are used to prevent injury to the public. In this regard, their most common type is a mesh (plastic). For fencing construction sites, it is considered the most optimal option. She can "catch" everything that falls from the scaffolding: garbage, leftover materials, tools, and even workers. Signal fences provide a visual indication of the construction site, warning citizens of the danger. For this, a special tape is often used. It is pulled between the pins, reinforced inearth.

Specifics

If the fence is intended for protection or protection, then it should only be solid. In some cases it is necessary to add additional elements. They can be visors, struts, a sidewalk with railings, etc. Depending on the availability and number of additional parts, the cost of structures is also determined. The material from which they are made also affects the price. Typically, a fence includes 3 elements: a frame, supports and filling.

Material options

As mentioned above, the construction site fencing must be stable, reliable, durable, easy to assemble, disassemble and transport. The traditional materials for the manufacture of such structures are wood and metal. Thanks to modern technology, their range has increased significantly. Currently, plastic is used quite often for fencing. The advantage of such constructions is as follows:

1. The current rules allow them to be installed.
2. The affordable cost of the material makes these fences attractive.
3. Installation does not require special equipment and additional workers.
4. No need to paint the structure.
5. Installation of plastic fences takes a minimum amount of time.
6. Designs are durable, lightweight and strong.

However, such fences have a rather serious drawback - they are unsuitable for useat sites where large-scale construction is underway. The situation is similar with chain-link structures. The undoubted advantages of the grid - its ease of installation and low cost - are suppressed by the norms of the state standard. Recently, profiled sheet fences have been installed quite often. The structures are easy to install and relatively inexpensive. In addition, these fences are easy to care for.

Mobile structures

Temporary fences of this type appeared relatively recently. They, like other structures, ensure the protection of citizens from accidents, the protection of the facility, and prevent the unauthorized appearance of strangers. Metal mobile elements are also used in the delimitation of parking spaces, marking the perimeter of the site. Installation does not require special equipment, no special knowledge is needed. Installation of elements is carried out in a short time. Panel sections are equipped with special fasteners. They prevent unwanted or accidental dismantling.

Conclusion

The construction site acts as a potentially hazardous facility. There is always the possibility of an accident here. In this regard, the persons responsible for the implementation of the work are obliged to take all necessary measures to ensure safety both inside the facility and outside it. Failure to comply with established regulations can end sadly not only for citizens, including workers, but also for managers responsible for construction. Currently, there is a large selection of materials and designs to ensure the safety of work, so those in charge caneasily select the proper object protection.
