Notice as to load.
Founde- Lion
BUILDING (CONSTRUCTION) REGULATIONS, 1956
(2) The test load shall not be applied to a reinforced concrete structure until 28 days after the date of concreting. During the tests, struts strong enough to take the whole of the combined dend load and test load shall be placed in position leaving a gap under the members.
(3) If, under test, no structural defects can be observed and if the deflection is not excessive, the structure shall be deemed to be satisfactory.
25. (1) In every storey of every building except where the floor is one used for purposes of habitation, there shall be exhibited by the owner, at each staircase or at some other appro- priate place, permanently and conspicuously, a notice, incised or embossed, of metal, plastic or other suitable material, in the following form, in letters and figures not less than inch high, staling the imposed load for which the floor has been designed.
Buildings Ordinance, 1955
NOTICE.
The imposed load on this floor is not to
exceed
lbs. per square foot.
(2) Where floors of different rooms or different parts of floors have been designed for different imposed loads, a notice in the above form shall be suitably displayed in each room or on each part of the floor as the case may be, indicating the variations.
PART IV.
Foundations.
26. The foundations of every building shall be constructed so as to be capable of sustaining safely and transmitting all the dead and imposed loads to the subsoil without impairing the stability of that or of any other building or road and without exceeding the appropriate limitations of permissible stresses.
BUILDING (CONSTRUCTION) REGULATIONS, 1956
27. Foundations shall be constructed
(1) of plain or reinforced concrete;
(2) at a depth below the surface of the ground sufficient to- (a) secure adequate bearing capacity of the soil; (b) avoid interference with drains or other services in
adjacent streets, roads or lanes;
(c) avoid overloading the foundations of adjacent
buildings or the soil supporting such foundations:
(3) of such thickness, not being less than 6 inches, and of such width as may be necessary to comply with the pro- visions of regulations 5 and 6:
Provided that where the foundation rests on sound hard rock the thickness of concrete need be no more than is necessary to provide a suitable level surface on which to construct the building:
(4) symmetrically under the centre of action of the load:
Provided that where the foundation lies on the boundary of the site, it may be wholly within such site, and shall be so designed, taking into account the eccen- tricity of loading, as to comply with regulation 5.

Con- atruction of founda tions.
28. (1) The pressure on the soil under any foundation shall Per- not at any point exceed that specified in Table VIII.
Provided that where adequate tests are made to determine the bearing capacity of the soil on any site, the calculated pressure on such soil may exceed those specified in Table VIII, but shall in no case exceed the proved safe bearing capacity.
(2) Where the foundation rests on culiesive soils, (Type 2 of Table VIII) the maximum pressure specified in the Table shall apply only to individual footings, walls or piers. The average pressure under a building calculated as the total load over that area of any one bay or other major portion of the structure, divided by that area, shall not exceed the appropriate pressure in the Table multiplied by the ratio of the width of the least individual footing to the width of the whole building.
