After removing all the defects should draw up a statement on the hidden work, allowing to carry out further work on the closure of other insulation structural elements. Drawing acts examination of the hidden works in cases where subsequent work should start after a long break should be made directly to the production subsequent work. Results of operational control should be registered in the magazine production work on the device insulation. When inspection control must check the quality of thermal insulation works selectively at the discretion of the customer or general contractor to test the effectiveness of a previous production control. This type of control can be performed at any stage of the construction of buildings. The results of quality control exercised by the technical supervision of the customer, the supervision, supervisory control, and the comments of persons who control the production and quality of work, shall be entered in the Journal production of works on thermal insulation and recorded also in the general journal papers (recommended form given in Appendix 1, * SNIP 3.01.01-85 *). All acceptance documentation must meet the requirements of SNIP 3.01.01-85 *. The prime contractor must submit to the representative of the customer magazine insulation work, acts of examination for hidden works, reports, executive documents, certificates and passports to apply materials, samples of insulation materials and the finished coating to match the requirements of the project, technical specifications, norms and standards. To assess the quality of insulation materials should be selected samples and carried out tests in accordance with applicable standards and specifications. The quality of works is ensured by requirements to comply with the necessary technological consistency in the implementation of related activities and technical supervision over the progress of work outlined in the Project Construction Management and Project of works, as well as in the Scheme operational quality control work.
