Their specification and structural performance, installation and range of sizes, make them particularly suitable for a wide number of applications. Relocatable and transportable accommodation units are delivered ready for immediate use. Units w

13、ithout wheels can either be craned, fork-lifted or winched into position or off-loaded from a flat-bed truck by one person using a telescopic jack-leg system. They can be linked end to end, side by side or end to side, or stacked to form a two or more storey structure. Since the 1960s, transportable

14、 accommodation units have been manufactured in large numbers under factory-controlled conditions. The volume and diversity of their manufacture has made it desirable to standardize the basic unit. This part of BS 6767 gives recommendations for design and construction of a basic unit. BS 6767-2 gives

15、 recommendations for design and installation of services and fittings with guidance on the necessary fire precautions, transportation, handling and siting. Safety matters have been given a high priority. In addition, recommendations on providing information to ensure correct unit identification, han

16、dling and siting, on the manufacturers certificate and also to be marked on the unit itself, have been included. Conformity with appropriate legislation depends upon the size and end-use of a unit. Some units are designated as permanent buildings and therefore need to conform to the appropriate buil

17、ding regulations applicable in England and Wales, Scotland and Northern Ireland. This part of BS 6767 gives recommendations for the safe use and other technical performance aspects of land-based transportable accommodation units classified as “exempt buildings” in the building regulations. It has be

18、en assumed in the drafting of this standard that the execution of its recommendations and provisions is entrusted to appropriately qualified and experienced people. In particular attention is drawn to: Building Regulations, 1991 1; Building Standards (Scotland) Regulations, 1990 2; Building Regulati

21、Traffic Act, 1972 19; Town and Country Planning Act, 1990 20; Town and Country Planning (Scotland) Act, 1997 21; 1 Scope This part of BS 6767 gives recommendations for the design and construction of the basic shell of single transportable accommodation units that are “exempt buildings” as defined by

22、 the appropriate building regulations applicable in England and Wales, Scotland and Northern Ireland. The units can be leg-mounted, skid-mounted, wheel-mounted or platform-mounted. Recommendations are also given for certain special considerations applying to some of the individual types. These recom

23、mendations are intended for use by designers and manufacturers of the basic units.
