Room layout

The Buildings Decree plays an important part in determining minimum required floorage and number and dimensions of the escape routes when workplaces are arranged in multiple rows. The below details the relevant information from the Buildings Decree: Section 7.13 on seat arrangements and Section 7.14 on aisles.

Section 7.13 Seat arrangement and additional layout

1. Rooms are laid out in such a way that:

a. at least 0.25 m² of floorage is available to each person without a seat;

b. at least 0.3 m² of floorage is available to each person with a seat, provided no fittings and furniture can be displaced or made to tip over due to crowding;

c. at least 0.5 m² of floorage is available to each person with a seat, if fittings and furniture can be displaced or made to tip over due to crowding.

The amount of floorage available to each person is calculated by deducting the floorage taken up by the fittings and furniture from the total habitable space floorage.

2. In rooms containing more than 100 seats, the seats are to be connected to each other or the floor in such a way that they cannot be displaced or made to tip over due to crowding, insofar as the seats are arranged in more then 4 rows of more than 4 seats.

3. When seats are arranged in rows, an unobstructed space is to exist between 2 rows of no less than 0.4 m wide between the normals of the parts of the rows closest to one another.

4. If a table is placed in a row as referred to in the third paragraph, this table is not to occupy any part of the unobstructed space as referred to in that paragraph.

5. Any row of seats with access to an aisle or exit on only end is to consist of no more than eight seats.

6. Any row of seats with access to an aisle or exit on both ends is to consist of no more than:

a. 16 seats if the unobstructed space referred to in the third paragraph is no wider than 0.45 m and the unobstructed passageway of the aisle or exit is at least 0.6 m wide;

b. 32 seats if the unobstructed space referred to in the third paragraph is no wider than 0.45 m and the unobstructed passageway of the aisle or exit is at least 0.6 m wide;

c. 50 seats if the unobstructed space referred to in the third paragraph is no wider than 0.45 m and the unobstructed passageway of the aisle or exit is at least 1,1 m wide.

Section 7.14 Aisles

1. Aisles between stands, stalls, shelves, stages and such fixtures in publicly accessible spaces are to be at least 1.1 m wide.

2. An unobstructed floor space is to exist in front of exits from a space as referred to in the first paragraph, which length and width are at least to equal the width of this exit.
