Determination of main materials and quality requirements in decoration engineering
(A) the determination of the main materials
1. All materials that have been selected by the design contractor and whose origin, brand and specifications have been specified in the bidding documents shall be selected according to the design requirements in principle. Real samples can only be purchased and used after being submitted for approval and sealed.
2. Mode design If the materials specified in the negotiation documents and design drawings have been changed to substitute products due to reasons such as procurement and delivery time, the physical samples shall be sent to the owner for seal after the design is approved, and then purchased and used after approval.
3. The submitted materials must meet the material quality standards stipulated by the state. If there is no national standard, it must also meet the relevant industry or local standards.
4. The use of ordinary materials should be confirmed by the design first, and then submitted to the owner for approval, and can only be purchased and used after approval.
