Efficient design of piled foundations
This guide has been prepared to provide housing sector guidance for the use of piled foundations for low-rise housing developments. ‘Low-rise housing’ is defined in BS 8103-1, Structural Design of Low Rise Buildings[1] as:
“detached, semi-detached and terraced houses and flats (with not more than four self contained dwelling units per floor accessible from one staircase), or not more than three storeys above ground intended for domestic occupation and of traditional masonry construction with timber roof and floors of timber or concrete.” For the purposes of this guide, low-rise housing is defined as housing of four storeys or less, and is not limited to traditional masonry forms of construction.
Although a wide variety of forms of construction are available, those used for low-rise housing in the UK have traditionally been limited to either unreinforced masonry construction or less commonly concrete and steel-framed buildings, which are generally constructed with masonry infill panels. More recently, timber-framed buildings have become more common on account of their ease of construction, reduced construction times, and improved sustainability credentials.
The masonry cladding to timber-framed structures is usually supported on the same foundations as the framed structure, and in terms of the tolerances to building movements, it is the cracking of the masonry and brittle finishes that are likely to be critical.
