Design of civil engineering works

All above-ground  LPG tanks are required  to be positioned  on a structural  work made  of incombustible materials (reinforced concrete).

The ground must be flat, horizontal, not subject to flooding and absent of any vegetation in the prescribed safety area.

On land that is slightly subject to flooding, the tank must be attached to the structural work. The foundations  of  the  structural  work  for  “mid-sized  and  large  bulk”  tanks  must  be performed by a specialist.

A soil survey must be done in order to determine the dimensions of cast-in concrete spread footings, according to soil loading and resistance.

Seismic events, if they exist, must be taken into account.

For   underground  tanks, refer to trench design and the criteria to be complied  with in the “civil engineering works” file.
