There is both British Standard and European Regulation to ensure that plant is comprehensively tested. Where we are engaged to provide a fully detailed specification and /or we undertake the management of a project we strictly enforce our witnessing of the regulatory tests undertaken by the Contractor. The results of the exercise are compared with the parameters and readings established by the Contractor, subsequent to which our findings are formally certified for issue to Clients (may be necessary for insurance purposes) on the prescriptive forms. In sequence with witness testing a formal schedule of defects (if any ) will be issued for action as appropriate by the Contractor.
