Before performing seat installation work in a stadium, you must first review all requirements. The geometry of the stadium bleachers and other factors that determine the capacity of the stadium spectators need to be finalized. When planning the stadium, the owners have clear requirements for the stadium’s auditorium capacity. By estimation, one can obtain an approximate amount of auditorium capacity. When the overall plan is reviewed, all the details of the venue need to be counted, and the subsequent work will become more complicated. Stadiums are public meeting places, especially in the auditorium. These buildings have various regulations and parameters set to ensure public safety. For example, in Germany, the “Guidelines for Promoting the Safety of Football” issued by the German Football Association has relevant parameters for auditorium seats. The seats installed in stadiums where football matches are held must meet these regulations and parameters. The German Football Association has the following rules for the auditoriums of the stadiums hosting the Bundesliga, Bundesliga and Bundesliga: The seats must be independent, numbered, reasonably shaped, properly installed and the seatback must not be less than 30 cm.

Safety is the most important

Many factors need to be taken into account when planning the audience area of ​​a venue, and these factors are often interrelated. For example, the size of the audience escape channel should be referenced to the audience area corresponding to it and the number of seats in each audience area. The auditorium in the stadium is usually divided into blocks, and each block has its total number of spectators and escape routes. Enclosed stadiums with roofs or partial roofs meet more safety requirements than open-air stadiums. The individual blocks of the auditorium are often not distinguished by visible boundaries, but by some other factor. The stadium’s standing seats can accommodate up to 2,500 people per block. The auditorium with seats can accommodate up to 1,200 people per block. (German standard) Such a block can be planned as 40 rows of 30 seats each or 40 rows of 30 seats each. At the final acceptance of the venue, the number of auditoriums and the width of the emergency exit shall be calculated by a specified equation scheme to obtain the complete evacuation time of the audience. Outdoor venues and standing auditorium venues have completely different detail requirements here than indoor venues with roofs. For venues where auditoriums usually stand outdoors, the two aisles allow for 40 auditoriums. The stadiums with indoor seats can accommodate up to 20 seats between every two aisles. Also, there must be at least two channels and an emergency exit for each audience block. The auditoriums in large stadiums are usually built like terraces on one floor after another. Therefore, the height and width of each step and the inclination and elevation of the auditorium on each floor need to be designed according to standards. Sometimes, to protect the audience, it is necessary to build a protective fence between the auditoriums. For example, when the height difference between the first and second-floor auditoriums is 50 cm, a protective fence with a height of 90 cm needs to be built in front of the first-floor auditorium, and the height of the protective fence of the second-floor stands must be 110 cm. If the maximum height difference between the two stands is not more than 100 cm and the guardrail is not built, the backrest height of the first row of seats needs to be more than 65 cm.

Layers of stands

The plan of the auditorium is based on the terraced geometry, and the capacity of the audience is based on the relevant regulations in public places and the DIN 13200-1 standard (rules for the arrangement of audience viewing areas). This standard stipulates that the height of the auditorium on each floor is 70 to 80 cm, the minimum span of the seat is 50 cm, and the width of the aisle is 35 cm (plus a safety distance of 5 cm). The seat is approximately 40 cm deep and 45 cm high. The minimum required space per seat is 50 x 80 cm. The structural design of some seats does not comply with the relevant regulations, especially those that affect the width of the aisle. Because the width of the auditorium is not very large. To solve the problem of the too-narrow aisle between auditoriums, people first thought of folding seats. However, the cost of this type of seat will be much more expensive than ordinary plastic seats. Another solution is to reduce the seat depth to less than 40 cm, but doing so will greatly reduce the comfort of the seat. The Italian or Spanish market in Southern Europe is somewhat confusing in this regard. Some stadiums in Spain or Italy still allow the use of seats with a depth of 60 cm, but some manufacturers are still producing smaller seats-only 30 cm deep, and the width of the seats is very small. This kind of seat is completely out of line with today’s industry standards and cannot be installed in stadiums.

VIP seats – spacious and comfortable

It is a reasonable design to give VIP auditoriums or business auditoriums a higher depth. As mentioned earlier, the business seats and the VIP area are usually separated by 50 cm on each floor, and the space between each seat is about 55 to 60 cm (sometimes larger). When the depth of the seat reaches about 100 cm, it will provide the ideal comfort for the person sitting on it. And seats on the grandstands of VIP boxes in stadiums usually have armrests. Generally, each seat in the box area will have at least two armrests or two adjacent seats share one armrest. The practice has proven that stadiums often make some modifications to the auditorium according to the needs of their operations. If you want to transform the audience area, which used to be ordinary plastic seats, into a business area, you can install armrests or cushions on the seats. The venue operator usually chooses to maximize the comfort of the seats in the business district without giving up a certain audience capacity. In the real case, the cost of upgrading the ordinary audience area to a box can often be fully recovered by selling expensive box tickets. The service fee charged by the integrated box is generally equivalent to the price of one or two tickets.
