问题：helpfortranslation依据招标文件中的要求，承建人 
依据文件中的要求，承建人在本工程中的所购买的材料必须满足设计和施工规范要求，并提供产品的合格证书（需要试验合格后材能使用的，同是时必须提供产品试验合格证和试验报告）经招标人、监理认可后方可使用，否则将视为违约，由此造成的一切由承建人承担，包括招标人由此产生的费用。
回答：In accordance wh the requirements in the RFP, the materials procured for this engineering project by the constructor shall comply with the terms and requirements of the norms for design and construction. The constructor shall also provide the qulified certificates for the products, (if the products need testing before adoption, the testing qulifications and testing reports shall also be provided,) and such certificates cannot be valid without the approval by the tender and supervisor. That no above-mentioned documents and certificates approved will be regarded as contract breaching, and all liabilities including the expenditures caused then will be solely sponsored by the constructor itself.
