BS 8297:2017

BS 8297:2017 gives recommendations and guidance for the design, manufacture, transportand installation of architectural precast concrete units in the form of:

• a) units supported by and fixed to a structural frame or wall to perform a cladding role;
• b) units which may neither be associated with, or form part of, a building;
• c) units used as permanent formwork in part or in whole, but limited to architectural elements; and
• d) the architectural function of a sandwich panel (see 3.7.3).

It includes recommendations on the measures which are to be taken to provide for permanent andtemporary movements and tolerances of the structure, to enable the cladding to perform its functionsatisfactorily. It gives the minimum standards needed and the materials and methods of fixings mostfrequently used. It applies to new buildings but many provisions might be applicable to alterations orrefurbishment of existing buildings.Guidance is given on the quality of the finished product and verification of performance. The designrecommendations given in this British Standard are based on limit state design principles.This British Standard is intended to be used in conjunction with BS EN 13369:2013 and BS EN 13670,but provides comprehensive guidance specifically in relation to architectural precast concretecladding and therefore takes precedence in the items addressed.This British Standard does not provide recommendations relevant to units incorporating glassfibre reinforced concrete (GFRC/GRC), semi-dry or small wet-cast masonry units instead of largerarchitectural wall cladding panels (see BS 1217), nor the design of the supporting structure to whichthe units might be attached.Cross References:BS EN 1090 (all parts)BS EN 480-1:2014BS 6180:2011BS 4449:2005+A3:2016BS EN ISO 11600:2003+A1:2011BS EN 10088-3:2014BS 6213:2000+A1:2010BS EN ISO 13788:2012BS EN 10080:2005BS EN 1008:2002BS 6093:2006+A1:2013BS 8221-1:2012BS 4483:2005BS EN 1015-12:2016BS 4482:2005BS EN 1996-2:2006BS EN ISO 3506-1:2009 BS 6744:2016BS EN 206:2013+A1:2016DD CEN/TS 772-22:2006BS EN 13055:2016BS EN 1993-1-4:2006+A1:2015BS EN 15167-1:2006BS 8500-2:2015+A1:2016BS EN 1992-1-1:2004+A1:2014BS EN 197-1:2011BS 8298-3:2010BS EN 1011-1:2009BS EN 1991-1-7:2006+A1:2014BS 7979:2016BS EN 14019:2016BS EN ISO 3506-2:2009BS EN 1992-1-2:2004 BS 6100-9:2007BS EN 12179:2000BS EN 450-1:2012NA to BS EN 1990:2002+A1:2005BS EN 1011-3:2000BS EN 13050:2011BS 8539:2012 BS EN 12878:2014BS 1881-208:1996BS EN 10088-2:2014PD CEN/TR 15739:2008BS ISO 15510:2014BS EN 1993-1-1:2005+A1:2014BS EN ISO 6946:2017BS 5606:1990BS EN 15651-1:2017BS EN 12155:2000BS EN 934-2:2009+A1:2012BS EN 1991-1-1:2002BS EN 1992-4BS EN 10027-2:2015BS 6954-2:1988BS 5080-1:1993BS 9999:2017BS 9991:2015BS 4255-1:1986BS 8000-2.2:1990BS EN 13369:2013BS 8202-1:1995BS EN 13670:2009BS 8000-0:2014BS EN 998-2:2016BS EN 14992:2007+A1:2012PD CEN/TR 15728:2016BS EN 13116:2001
