Temporary fencing of a construction site

In accordance with the requirements of SNiP 3.01.01-85, each construction facility (erected or repaired) is subject to fencing, since the work carried out on the site can be dangerous for the people around. Typically, in such areas there are a variety of materials, overall equipment and structures, unprofessional handling of which leads to injuries. To avoid it, a law was passed obliging the use of a special fencing of the construction site, which is a metal section on support blocks. It remains until the end of all events, and its presence is regulated by the number GOST 23407-78.

Fence for fencing the territory of construction sites: features and classification

First of all, it is necessary to determine the primary norms that must be met by the fences of the inventory of construction sites and sites. Among them:

• The presence of wickets and travel gates for the free movement of vehicles and people.
• Assembly / disassembly of structures and uniformity of parts, fasteners.
• Regulated height:
  • 200 cm (visor and visorless security and protective fencing),
  • 160 cm (protective without visor),
  • 120 cm (specific workplace).
• The distance between the sections is up to 600 cm.
• The degree of rarefaction is no more than 100 mm.
• Pavement gaps - up to 5 mm.
• For the passage of people - not less than 1.2 m.
• The stability of the fence is at least 200 kg per sq. cm.
• Visor rise - 20 °.

Compliance with all points when fencing the construction site is monitored by supervisory authorities that inspect technical processes at various facilities.

Types of fences

Depending on the purpose of installation, products are divided into 3 categories:

• signal,
• protective,
• security.

They prefer to buy construction site fences of the first type to clearly indicate that work is underway here. They are practically indistinguishable from ordinary fences that surround houses and industrial buildings.

Protective ones are able to protect from injury, therefore, their main element, in addition to the supporting concrete block of a special section, is the facade mesh. It prevents tools, debris, etc. from falling off the construction scale.

Signals serve to visually delineate the site and warn of hazards. They have similar tasks with anti-ram barriers with a chain stretched between them.

From the point of view of design, there are:

• rackmount,
• panel (mesh, solid),
• combined.

If the fence of a construction site in Moscow performs a protective or security function, then it is implemented exclusively solid. Most preferred are metal mesh fences mounted on a concrete base for temporary fencing. Their advantages include:

1. Relatively high strength and deformation resistance.
2. Partial absorption of industrial noise.
3. Presentable view (especially in city conditions).
4. Operational installation.
5. The difficulty of overcoming such an obstacle.

You can separately buy blocks of a special section and the fences themselves from us. Their fastening is not difficult.

Installation of construction site fencing

Installation is similar to the construction of a classic fence. The metal fencing of the construction site is installed according to the following algorithm:

• Preparation. Before starting work, a diagram is drawn up and the amount of material is determined based on the size of the construction area.
• Installation of welded frames. Each unit is installed on an FBS block 2400x600x400 or other dimensions. Wickets / gates must have corner posts.
• Fastening guides. When working with components, welding is often used. Fixation also takes place with the help of fittings.
• Reflective paint application for better visibility of the fence.

To find out the price for a foundation block 2400x600x400 and other products to calculate the final amount, visit the corresponding section or contact our managers. They will also advise on the cost of installing structures.

Stroytekhtsentr LLC produces collapsible portable fences in accordance with GOST 23407-78. The structures are characterized by mobility, ease of installation, reliability and safety. This is an excellent solution for temporarily restricting access to a facility under construction, departmental territory, dividing the flow of people at cultural events, etc.

Features of metal fences for construction sites "ARIS" A-32

The structures are made on the basis of a strong galvanized metal frame filled with a welded grating. The temporary fence is installed on universal concrete blocks, which act as a base for the fence elements. Special clamps are used to connect the steel sheets. The reliability and safety of the finished structure is ensured by the thoughtfulness of every detail.
The main advantages of ARIS mobile fences:

• installation and dismantling of the structure is carried out using a simple hand tool, does not require special knowledge and skills;
• the cost of a temporary fence is much lower than that of a permanent one;
• for the manufacture of fences, the Stroytekhtsentr company uses high-quality steel, resistant to mechanical stress;
• mobile fences reliably protect bystanders from injury at a facility under construction or in another dangerous area;
• the necessary information can be placed on the structure without the risk of damage to the material;
• the service life of fences and galvanized steel reaches 10 years or more in different weather conditions.

Technical characteristics of temporary fencing for construction sites

Technical requirements for mobile fences

The construction of a temporary fence at the construction site allows you to secure the work on it, to avoid accidents and injury to people. That is why serious requirements are imposed on this type of protective structures, reflected in the established state standard.

According to the main provisions of the document, as well as the requirements of SNiP, the fence must meet certain design requirements:

1. Construction site fencing must be quickly and easily disassembled, therefore standardized fittings must be used.
2. The sections of the structure must be made in the form of rectangles, without sharp corners, protrusions and traumatic elements. To fence a specific site on the construction site, use a 1.2 m high mesh. The permissible height of the entire fence can be at least 2 m, the section length - from 1.2 to 2 m.
3. The fence should be provided with gates for people working at the construction site and gates for the passage of vehicles involved in the construction.

It is also necessary that the temporary fencing of construction sites comply with the operating rules. Therefore, it should be:

• Reliable and resistant to mechanical damage and atmospheric stress (gusts of wind, precipitation). Load on 1 square meter of fence - not less than 200 kg.
• Manufactured from materials with a quality certificate and a long service life, not exceeding 10 years.
• Installed from the sidewalk at a distance of at least 1.5 m, which provides a safe passage for pedestrians. For greater safety, the passage should be equipped with a protective canopy and railings.

Aris's mobile fences for construction sites fully comply with the established requirements of the standards. By approaching their construction responsibly, you can avoid serious consequences that pose a threat to human life or harm his health.

Any construction, especially in urban areas, poses a direct threat to the safety of citizens. This is due to the fact that the objects use dimensional equipment and materials that can fall. Therefore, for the entire period of work, a construction site fence should be installed. Requirements for such structures are defined in standards and regulations. Let us consider these constructions in more detail below.

General rules

The organization of the construction site and its individual sections must ensure safe working conditions and proper sanitary and hygienic services, exclude and prevent possible threats. When carrying out activities at the facility, the customer is responsible for providing the contractor with a work front and carrying out labor protection measures. The latter, in particular, includes the construction site fencing.

Security

In the process of performing work related to the organization of a construction site in conditions of reconstruction, it is necessary to perform the following generally accepted measures:

1. Determination of the boundaries of hazardous areas.
2. Fencing of the construction site and its individual sections.
3. Providing the necessary lighting, driveways, walkways. A separate electrical wiring is allocated for its organization. It should not be connected to the power grid of the reconstructed facility.
4. Organization of driveways for assembly equipment and transport, walkways for workers, storage areas for materials and structures.
5. Equipping facilities with primary extinguishing agents.
6. compliance with sanitary and hygienic standards in the manner determined for the enterprise.
7. Installation

GOST 23407.78: Inventory fences for construction sites

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

1. Temporary partitions and walls. They ensure the separation of workplaces and areas for the implementation of installation activities.
2. Protective decks. They are used to prevent the falling of materials and objects in the premises where production is carried out.
3. Coatings for protection against cold and atmospheric precipitation.
4. Temporary fencing of the construction site, warning about the boundaries of the territories and areas on which construction and installation work is carried out.
5. Structures to prevent workers from falling from a height.
6. Other fences, light shelters, screens. They are used to provide protection against glare during electric welding, heat exposure, protection of glass from destruction during explosive activities, to prevent contamination of equipment in the workshops of the enterprise.

Construction site fencing is manufactured for specific conditions. Their design must be reusable. Any temporary fencing on a construction site must be convenient for transportation, reliable, durable, effective both during the day and at night.

Additional rules

The exits and entrances of the operated structure must be equipped outside the boundaries of hazardous areas. At the entrance to the construction site, a transport movement scheme is established. The sides of driveways and roads are equipped with clearly visible signs regulating the traffic order. The builders must be provided with sanitary facilities in accordance with current regulations. At objects classified as explosion 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 the process of performing installation activities in gas-polluted rooms, as well as in areas that are located below the floor / ground level, an air analysis is carried out every day before the start of the shift.

Warehousing of materials and structures

It should be carried out in accordance with the provisions that contain technical documents and GOST. The construction site fences are designed in such a way that when loading / unloading materials and structures with the help of special equipment, complete safety of workers is ensured. Storage locations are determined and agreed with the management of the enterprise. Separate structures and stacks are located so that they do not block access to inspection units of existing communications. Their placement on roads, crane and railway tracks is not allowed. When storing on bulk soils, measures are taken to exclude the likelihood 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 DNAP. When loading, unloading and transporting using cars or trains, traffic rules and norms defined in the relevant documents should be followed. The speed of movement of transport on the territory of the reconstructed object on straight and fairly well-visible sections cannot be higher than 10 km / h. At the exits, including from the side passage to the main driveway or to the road-gu with in-ten-sive traffic, entrances, inside workshops, at U-turns, intersections, when moving in reverse, in dense fog, it should not exceed 5 km / h. When transporting structures in and with limited dimensions of the passage, red flags are fixed on the 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 rules for ensuring safety at facilities. The standards were adopted back in Soviet times. Taking into account the development of technology, they were adapted to modern conditions. In 1979, GOST "Inventory fencing of construction sites" was approved and put into effect. In accordance with these documents, it is not allowed to carry out construction and installation work on an object or part of it without establishing special protective structures.

Key prescriptions

Construction site fencing must comply with state-approved samples. The design should provide for wickets or gates to ensure the free movement of workers and transport. 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 correspond to the established parameters. The panels are made in the form of a rectangle. Their length, as well as the gaps between the racks, are determined according to the norms: from 1.2 to 2 m and no more than 6 m, respectively. Between the parts, it is necessary to maintain a degree of rarefaction of 80-100 mm. An exception is construction sites. There should be no gaps in excess of 5 mm in the sidewalk flooring. The protective shields must be turned 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 railings must be attached to the canopy or to the upper border of the fence. In addition, protective stripes are provided at a height of 50 cm and 1.1 m from the roadway. The construction site fence must be of such a design that it can be repaired and removed while maintaining adequate strength. Responsible persons are obliged to take measures to prevent rotting and rust spreading through the elements. The presence of a slope on the terrain must not threaten the safety fence. The structure must be coated with an appropriate dye composition. It must be free of potentially traumatic elements (hooks, corners, and so on).

The construction site fencing is made of reliable materials to ensure its stability. The structure must withstand the fall of objects of a certain weight, but not less than 200 kg / cm 2, 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 sidewalk decking panels, this period must be at least 5 years.

Classification of structures

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

1. Signal, unambiguously and clearly indicating that construction and installation work is underway on the territory.
2. Protective, ensuring the safety of people from injury.
3. Security, preventing unauthorized entry of strangers into the object.

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

1. Rack.
2. Panel. They, in turn, are subdivided 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 mesh (plastic). For fencing construction sites, it is considered the most optimal option. She can "catch" everything that falls from the forests: garbage, remnants of materials, tools and even workers. Signal fences provide a visual indication of the construction site, alerting citizens to danger. For this, a special tape is often used. It is pulled between the pins fixed in the ground.

Specificity

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

Material options

As mentioned above, the construction site fence must be stable, reliable, durable, easy to assemble, disassemble and transport. Wood and metal are traditional materials for the manufacture of such structures. Thanks to modern technologies, their range has increased significantly. Nowadays, plastic is used quite often for fences. The advantages of such designs are as follows:

1. Current regulations allow their installation.
2. The democratic cost of the material makes such fences attractive.
3. Installation does not require special equipment and additional workers.
4. There is no need to paint the structure.
5. Installation of plastic fences takes a minimum amount of time.
6. The structures are durable, lightweight and durable.

However, such fences also have a rather serious drawback - they are unsuitable for use at facilities 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, professional sheet fences have been installed quite often. The structures are easy to assemble and relatively inexpensive. In addition, such fences are easy to maintain.

Mobile constructions

Temporary fences of this type have appeared relatively recently. They, like other structures, provide protection for citizens from accidents, guard the facility, and prevent unauthorized appearance of strangers. Metal mobile elements are also used for delimiting parking lots, marking the perimeter of the site. No special equipment is required during installation, no special knowledge is required. Installation of elements is carried out in a short time. Panel sections are equipped with special fasteners. They eliminate unwanted or accidental dismantling.

Conclusion

The construction site acts as a potentially hazardous facility. There is always the possibility of an accident. 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 the established instructions can end up sadly not only for citizens, including workers, but also for managers in charge of construction. Currently, there is a large selection of materials and structures to ensure the safety of work, so the responsible persons can easily select the proper protection of the object.

Any construction is associated with the risk of injury. That is why construction sites need to be fenced off to reduce this likelihood. Let's figure out together what the law requires, what the temporary fences of the construction site can be, and what they can be made of.

SNiP 3.01.01-85, GOST 23407-78, SNiP 12-03-2001, "Rules for labor protection in construction" (order No. 336n of the Ministry of Labor of Russia dated 01.06.2015) - all these documents regulate safety measures at construction sites, in in particular, indicate what the fence should be, installed at the time of work. According to these rules, it is impossible to start construction before the fence is erected, otherwise a fine will be threatened.

We are sure that you yourself will not want strangers walking around your construction site, children playing, and intruders trying to take out the materials already delivered. Therefore, the fence becomes a necessity.

All temporary fences of construction sites are divided into three types:

1. Signal. They clearly show that the dangerous construction zone begins here. They may simply be special signal tapes, similar to those used by police officers. Or light plastic nets of bright colors - orange or red. The main thing is to highlight the construction site, indicate the territory that cannot be entered.
2. Security. Such fences are designed to close the construction site from outsiders, to prevent them from entering there. Security fences are often like permanent structures, and can last for decades even when the construction is over.
3. Protective. Their purpose is to protect people from injury. Very often, protective and security fences are built in the form of a high fence with a visor, which helps to avoid falling building materials on the heads of passers-by. In addition, facade mesh is also used as a means to prevent heavy objects from falling from the height of the house under construction.

By design, temporary fences are divided into rack-mounted, panel-mounted and panel-rack-mounted. Panel fencing is either sparse or solid.

Important! Protective and security fences can be extremely solid!

By design, the fences are divided into:

1. Simple, no additional elements. That is, just a fence, solid or sparse.
2. With additional elements. For example, canopies over a wicket, gate, sidewalk, if it is located next to the site. Railings, struts, temporary sidewalks - boardwalk paths can also act as additional elements. It is clear that the second type of construction site fencing will be significantly more expensive than the first.

You can build a temporary fence for a construction site from a variety of materials:

• Mesh fabric.
• Special signal tape.
• Wood such as old boards.
• Slate.
• Metal profile.
• Steel sheets.
• Plastic.
• Metal concrete.

If we talk about the most popular options, then metal concrete is used most often in the construction of large objects, because the installation of such a heavy, capital fence itself is already an expensive pleasure. Ordinary site owners who have started construction more often use wood, profiled sheets, light plastic sections.

If necessary, you can rent a temporary fence, which will be quickly assembled on site, and after the completion of the work, it will go to the new construction site. This is an inexpensive option, especially if the company offers rental with installation and subsequent dismantling. The downside of this method is that it is sometimes difficult to say how long the construction will last, that is, the fencing lease will have to be renewed and paid extra for it.

Important! Temporary fencing can be supplemented with lighting placed on racks and special signs warning of danger.

The legislation puts forward the following requirements for temporary fences of construction sites:

• Gates for special equipment and wickets for people are required.
• The height of protective and security structures should be at least 2 meters, protective fences without canopies - 1.6 meters, with canopies - also 2 meters. The height of the fence of the entire work site is not less than 1.2 meters.
• Visors must be installed if the construction site is adjacent to a place of busy traffic. In this case, the angle of ascent of the visor towards the road must be at least 20 degrees.

Important! The canopy must be strong enough to withstand the snow load.

• In the case of construction of a temporary walkway, the gaps in it should not exceed 5 millimeters. The width of the sidewalk is at least 1.2 meters.
• Rectangular fence panels should be 1.2, 1.6 or 2 meters long.
• The fence must be strong and safe enough without snags or sharp corners.

The cost of the simplest mesh temporary fence, installed on concrete blocks, will be about 1,500-2,500 rubles, depending on the height (the standard length is two meters) and the presence of a protective coating in the form of paint. Renting one such section will cost about 10-30 rubles per day.
