It is intended that this standard specification will be used generally as a means of measurement and assessment of a contractor’s performance and, specifically, to demonstrate compliance and competence under the BESA Inspection and Assessment arrangements.


It is envisaged that TR/20 be used either in the absence of a client specification or by specific reference as an integral part of such a specification. It is also proposed that TR/20 be used as a quality benchmark whereby any shortfall identified within an alternative specification is drawn to the client’s attention.
