The information contained here was prepared basing on the experience of the company PS NAMIOTY and are a guide for potential clients and have only informational purposes. They do not constitute the basis for claims, binding information can be provided by the institutions adequately created for this purpose.

The company PS NAMIOTY manufactures tents standard and suitable for the 1st wind zone (according to Polish norm PN-77/B-02011) and 1st, 2nd and 3rd snow zones (according to Polish norm PN-80/B-02010/Az1: 2006). We also produce hall tents, suitable for both 2nd and 3rd wind zones. Each tent produced by us has a dossier, which contains information on the strength of construction and material used. A certified engineer of civil engineering works has verified the dossiers.
Below we present maps defining the area of wind and snow zones according to norms applicable on Polish territory. Those maps cannot constitute the basis for claims in cases concerning the strength of the structure; they have only an illustrative character for orientation in the wind and snow zones.

WIND LOAD BY PN-77/B-02011

Map of wind load zones by PN-77/B-02011

ZONE 1 - covers the largest part of the country.
ZONE 2 - covers the strip of land from the dorsal lot  of Pomeranian Lake District hills to the sea shore and
                     the narrow strip of land  around the Gulf of Gdansk and the range of Łysogóra. In zone 2 two sub-zones  were
                      marked off, west of Władysławowo.  
ZONE 2a - coastal strip of land with a width of about  2 km.
ZONE 2b - coastal strip of the sea and the strip of  dunes with a width 200 m.
ZONE 3 - covers the area from the Sudeten foothills  and Carpathian foothills. 
    

Zone boundaries should be treated as a strip of land, with a width of about 5 km, assuming on the borderline the value qk of one or the other zone, depending on configuration of the terrain and exposure of the building.

Zone	Vk	qk
	m/s	Pa
I	20	250
II (III 200 m.above sea level)	24	350
IIa (III 400 m.above sea level)	27	450
IIb (III 600 mabove sea level)	30	550
III	24-47*	**

Wind load shall be determined assuming that the wind blows horizontally from the direction giving the most unfavourable load for the building, item, or barrier, and that all the surfaces of components or barriers are subject to perpendicular wind thrust, or suction. In the case of surfaces parallel to the direction of wind or swept from it by an angle no greater than 15 degrees also tangential load is taken into account.

SNOW LOAD BY PN-80/B-02010/Az1: 200

Map of areas with snow loads by PN-80/B-02010/Az1: 2006

Zone	Qk ,  kN/m2
1	0,007A - 1,4;    Qk > 0,70
2	0,9
3	0,006A - 0,6;    Qk > 1,2
4	1,6
5	0,93exp(0,00134A);    Qk > 2,0
NOTE: A = Hight above sea level (meters)

Characteristic ground snow load Qk according to PN-80/B-02010/Az1: 2006 is applicable for facilities constructed after 2nd October 2006.

The development of meteorological observations and measurements made the roof snow load began to be treated as a function of the ground snow load, which could be determined on the basis of multiannual measurements, carried out by the same methods and measurement techniques. Ground snow load has become a basic reference volume, used to determine roof snow loads.

According to the norm PN-80/B-02010 characteristic value of the roof snow load Sk per 1 sq, m. of horizontal projection is determined according to the formula
Sk = Qk x C [kN/m2], where Qk - snow load characteristic for the ground,
C - the roof shape ratio. Values of characteristic ground snow loads Qk, depending on the zone marked on the map of Poland should be taken as equal to:

- 0,7 kN/m2 in zone I,
- 0,9 kN/m2 in zone II,
- 1,1 kN/m2 in zone III,
- 0,003 H > 0,9 - in zone IV,

although this finding relates to the height above sea level H <1000 m for the areas located above the Qk load should be determined individually.

HALL TENTS AND THE BUILDING LAW

Hall tents must be attached to the ground for safety reasons (details of affixing see the tab HALL TENT BOLTING), which results in classifying them as structures by the Building Law.
We quote the Building Law Act presenting the classification of objects:

"ACT
of 7 July 1994
Building Law

Art. 1.
The act - Building Law, hereinafter referred to as "the Act" regulates activities involving
design, construction, maintenance and demolition of buildings and defines the principles of public authorities actions in these areas.

Art. 3.
Whenever the act refers to:

2) building - it should be understood as such building work, which is permanently
attached to the ground, separated from the space through the construction of bulkheads
and has the foundation and roof;

3) structure - it should be understood as any building work other than the building or a small architecture structure object, such as: airports, roads, railways, bridges, viaducts, flyovers, tunnels, culverts, technical networks, free-standing antenna towers, freestanding, attached to the ground permanent advertising equipment, earthworks, defensive (fortifications), protective, hydraulic engineering structures, tanks, freestanding plants or technical equipment, sewage treatment plants, landfills, water treatment plants, retaining structures, aboveground and underground pedestrian crossings, land development network, sport structures, cemeteries, monuments, as well as building elements of technical devices (boilers, industrial furnaces, wind power and other devices), and foundations for machinery and equipment, as distinct from the technical part of the objects that make up the entire usable;

5) temporary construction site - it should be understood as a work intended for temporary use for a period shorter than its technical life, intended to transfer to another location or demolition, as well as a structure not connected permanently to the ground, like shooting ranges, street kiosks, street sales and exhibition pavilions, tent, pneumatic and roof coatings, entertainment equipment, crew wagons, container objects;

Art. 4.
Everyone has the right to build on the plot of land, if he proves the right to dispose of the property for construction purposes, subject to compliance of the building intention with the provisions.

Art. 5.
1. Construction structure together with associated building equipment must be taking into account the expected duration of use, design and build in the manner specified in the provisions, including the technical and construction provisions, as well as in accordance with the technical knowledge, providing:
1) meeting the basic requirements concerning:
a) the safety of the construction,
b) the fire safety,
c) the user security,
d) the appropriate conditions of hygiene and health and environmental protection,
e) protection against noise and vibration,
f) the energy savings and adequate thermal insulation compartments;
2) the use conditions in accordance with the object purpose, in particular in the scope of:
a) water supply and electricity, and, if appropriate, in heating and fuel efficiency assuming effective use of these factors,
b) the removal of sewage, rainwater and waste;
3) the possibility of maintaining technical state;
4) the necessary conditions for the use of public buildings and residential multi-family housing for persons with disabilities, in particular, moving on a wheelchair;
5) the conditions of occupational safety and health;
6) protection of the public, in accordance with the requirements of civil defence;
7) protection of buildings listed in the register of monuments and sites covered by
protection of conservation;
8) the appropriate location on the construction plot;
9) respect for reasonable interests of third parties, occurring in the area of the facility impact, including providing access to a public road;
10) the safety and health conditions of persons staying n the construction site.

Art. 6.
For building plots or land which is provided for construction of facilities or functionally related groups of building structures, an appropriate management shall be designed, in accordance with the requirements of Article 5, realising it before handing over of those structures (groups) to use, and ensure the maintenance of the land in proper technical and use condition for the existence of structures (groups).

Art. 29.
1. Building permits is not required for construction of:
12) temporary structures, not connected permanently with the ground and planned for demolition or move to another place within the period specified in the notification referred to in Article 30 (1), but not later than 120 days from the date of construction commencement, specified in the declaration;
24) facilities for temporary use during the execution of works, located on the building site, and setting of the crew wagons used for carrying out the building works, geological studies, and geodetic measurements; "

Building permit are issued by Poviat and Communal Building Departments, which, depending on the region, interpret the building law differently and the classification of tents depends on these authorities because they are not clearly classified in the building law. In order to obtain accurate information for your region you should address the Poviat and Communal Building Departments.
