GB 50500-2013 第7.1.4条
| **** | **Missing items in the bill of quantities**: Where project quantities increase or decrease due to engineering changes, if the contract contains applicable or similar items, the contract unit price shall apply; if there are no applicable or similar items, the contractor shall propose a price, which shall be executed after confirmation by the employer. **Fine decoration of hotel guest rooms and public areas, as well as adjustments to MEP terminal devices**, often trigger this clause. |
