英语翻译
20% of the Contract Price equal to [USD 6,320.000] shall be paid to the Contractor on the date of Contract’s signature against a bank guarantee (advance payment bond) of the same value to be submitted by the Contractor to the Owner with at least 5 banking days prior to the date of payment.
请帮忙翻译上段文字,

Answer 1

合同金额的20%(即6,320美元)将于合同签署之日付给承包商,但承包商须在付款前5个银行工作日内将相同金额的银行保函先交予所有者.
