Under the guidance of the construction unit, in accordance with the requirements of the construction unit, design and construction are carried out according to the actual conditions on site, and the on-site engineering quantity visa will be issued for the actual construction quantity on site, and the settlement will be based on Guizhou Province 20XX related quotas as stipulated in the contract.
On July 19, 20XX, the project passed the unit's project completion acceptance. Based on the actual acceptance results, our unit completed the settlement of the project.

1. Note: Items 1 and 2 of Table 2:
Because there are no construction drawings for item 1 and 2, and there are power cables, water supply pipes, and machinery at the lower part of the southern gate. It cannot be constructed normally and relies entirely on manual construction, which increases the construction cost. Moreover, Item 1 and 2 include two parts of the courtyard in the south and north. If the amount of work on both sides is (4685.31+907.62), it will not be enough for the material cost. The construction quantity reported by the construction party is based on the unit of one side. The amount reported (①5440.55200 yuan) is the project quantity of two units in the south and north districts.
Item 2: At that time, the bidding price for the entire project volume was 7.65 million yuan. After negotiation in Tongxiang, Zhejiang Province, the price was discounted to 6.5 million yuan as the general contracting price, which was 17.69%. When I bought steel in April 20XX, the material price was 4,260 yuan/ton, and the unit price of C-shaped steel was 4,400 yuan/ton. When I bought materials for both sides of the door later, the price of steel had increased, and the actual purchase price was 4,650 yuan/ton.
① Material cost: 4650 yuan/ton
② Processing and production: 1460 yuan/ton
③ Installation cost and labor: 780 yuan/ton
④ Auxiliary materials and fire retardant coatings are 570 yuan/ton. Although the portals on both sides only weigh 7.681 tons, one shift of crane (hoisting machine) was used for installation. Therefore, the equivalent price is 7,450 yuan/ton. At that time, Manager Chen made a printing error after sorting it out and reported it as 2,800 yuan/ton.

Fujian Rongqiao Real Estate Co., Ltd.:
Entrusted by your company, our institute undertakes the task of monitoring the basement foundation pits of buildings 8#~10# in Rongqiao Jinjiang Yuefu Garden (South District). The monitoring work began on April 27, 20XX. As of the end of October 22, 20XX, the actual workload completed has increased compared with the estimated workload. The main reason is the extension of the construction period. The details are now explained as follows:
1. Our hospital’s basic The estimated workload of each monitoring project of the pit monitoring project is 35 times, based on the monitoring frequency specified in the specifications as shown in the table below and the estimated construction period (about 3 months) provided by the owner to our institute.
2. The extension of the basement construction period has led to an increase in monitoring workload. The estimated construction period provided by the owner to our hospital is about 3 months. Our hospital has started to implement monitoring work since entering the site on April 27, 20XX. On July 20, 20XX, the completed workload of each monitoring project reached 35 times. However, at this time, the earthwork in the basement of Building 10# of the project has not yet been excavated, and the foundation pits in the basements of Buildings 8# and 9# have not yet been backfilled. Our hospital will feedback this situation to your company to ask whether we will continue to monitor this site in accordance with the monitoring frequency required by the specifications and design. To monitor the foundation pit, please ask the relevant leaders of your company and obtain the written consent of your company’s leaders to continue monitoring the foundation pit. By October 22, 20XX, our institute has completed all monitoring tasks for the foundation pit project.
Therefore, the above-mentioned extension of the construction period (from the expected 3 months to nearly 6 months) has resulted in an increase in the monitoring workload of this foundation pit project compared with the estimated workload. The on-site implementation and completed workload of our hospital's monitoring work on the project have been confirmed by the owner's on-site representatives and other personnel.
