题目：
某政府机关新建高层办公大楼幕墙工程公开招标，有6家具有建筑幕墙施工资质的企业参加投标。开标后，招标人按照法定程序组织评标委员会进行评标,评标的标准和方法在开标会议上公布，并作为《招标文件》附件发送给各投标人。评标委员会在对各投标人的资信、商务、技术标书评审过程中发现：A投标人出具的《安全生产许可证》巳过期；投标人B在投标函上填写的报价内容，大写与小写不一致。经综合评审按照得分的多少，评标委员会推荐C、D、E公司分别为第一、第二和第三中标候选人，后招标人认为D公司具有办公建筑幕墙工程丰富的施工经验，最后宣布由D公司中标。在签订合同时，考虑到D公司投标报价高于C公司，招标人要求D公司以C公司的投标报价承包本项目，D公司欣然同意并签订了合同。
