This part covers the loadings on a building, and the construction of the structural elements including the foundations, walls, floors, roofs and chimneys. The building must also be constructed so that the risk of ground movement, will not impair its stability. Simple design rules and guides are also supplied for domestic buildings, including garages and outbuildings, and small non-residential buildings.

Taller buildings also need to be constructed so that in the event of an accident the building will not collapse to a greater extent than the area affected by the incident.

Approved Document A

PDF file: 5.33 MB, 54 pages

The requirements in this edition of Approved Document A are as follows:

A1 – Loading

(1) The building shall be constructed so that the combined dead, imposed and wind loads are sustained and transmitted by it to the ground:
(a) safely; and
(b) without causing such deflection or deformation of any part of the building, or such movement of the ground, as will impair the stability of any part of another building.
(2) In assessing whether a building complies with sub paragraph (1) regard shall be had to the imposed and wind loads to which it is likely to be subjected in the ordinary course of its use for the purpose for which it is intended.

Limits on application

None

A2 – Ground Movement

The building shall be constructed so that ground movement caused by:-
(a) swelling, shrinkage or freezing of the subsoil; or
(b) land-slip or subsidence (other than subsidence arising from shrinkage, in so far as the risk can be reasonably foreseen), will not impair the stability of any part of the building.

Limits on application

None

A3 – Disproportionate Collapse

The building shall be constructed so that in the event of an accident the building will not suffer collapse to an extent disproportionate to the cause .

Limits on application

None
