Blast Resistant Portable Building Accommodation where design approval for the structure of the unit has been designed and manufactured to meet the blast resistance criteria under the following conditions:

• Walls – Reflected overpressure of 650 mbar for a positive phase duration on 100msec
• Roof – The roof for the 650mbar module (reflected on the front face) would need to be able to resist the 320mbar pressure (side on or overpressure) for the duration of 100msec
• Floor– Reflected overpressure of 650mbar for a positive phase duration of 100msec
• Windows – Reflected overpressure of 650mbar for a positive phase duration of 100msec
• Door – Reflected overpressure of 650mbar for a positive phase duration of 100msec
• Door has been classified as Category 1

All Blast loadings assumed to be of a shock wave form i.e instantaneously rising at time t=0 to the maximum overpressure and decaying linearly to zero mbar at t=100msec.

Units can be manufactured any size up to 32ft x 10ft. Designs for lower specifications are also available.

If you need a Fire Rated Building (fully certificated) then the Fire Rated Buildings can meet your needs.

Fire Rated Buildings can be manufactured with a choice of flat sided or corrugated steel side walls and all windows have a neat and tidy fire curtain installed that will automatically drop in the event of a fire, thus preventing fire spreading from the windows.

The Fire Rated Buildings covers all unit sizes from 16ft x 10ft up to and including 32ft x 10ft.

Electrical & Plumbing fit: electrics to IEE 17th Edition with all distribution boards with MCB’s and RCD. All Gas fitting CORGI approved.

Locking systems: all accommodation units have High Security Multi-Locking System doors as standard.
