变更与签证：口头指示变书面，按合同期限报价

如何在合同规定的期限内，把业主代表的口头指令变成有计价的变更？

口头指示不是变更：当天给监理人发工作联系单，拿到书面指示后14天内提交变更估价申请；监理人7天内审查，甲方14天内审批，逾期不批也不提异议视为认可。估价按示范文本顺序：相同项目用原单价，类似项目参照，工程量变化超过15%的按成本加利润商定。示例中取消隔墙减 8.64 万，吊顶加 30.95 万，风管风口加 26.8 万，净增 491,120 元（不含税），合同金额由 3,690.46 万元变为约 3,744 万元；计日工三张签证共 52,300 元，每张都要写明时间、部位和内容、数量或工日、双方签认。

A verbal instruction is not a change: send the supervisor a work contact form the same day, and submit the change valuation request within 14 days of the written instruction; the supervisor reviews within 7 days and the employer approves within 14 days, and silence counts as acceptance. Pricing follows the model-form order: same item uses the original rate, a similar item uses a similar rate, and a quantity change above 15% is agreed on cost plus profit. In the example, removing the partition is -CNY 86,400, the ceiling +CNY 309,500 and the ducts and outlets +CNY 268,000, a net CNY 491,120 before VAT; the contract rises from CNY 36.9046 million to about CNY 37.44 million. Three daywork visas total CNY 52,300, and each needs date, location and content, quantity or days, and signatures from both sides.
