Construction period extension application report 2 on May 15, 20XX

Foshan Lingnan Tiandi LOT constructed by our company -D apartment hotel project general contracting construction project. Due to various reasons, the project cannot meet the completion requirements as scheduled in the contract. Now our company will analyze the specific reasons for the delay in the construction period and respectfully submit an application for a construction period extension to your company. The details are as follows:

1. Overview of Lingnan Tiandi and introduction to important and difficult points

This project has a total land area of ??16,500 m2, a total construction area of ??77,060 m2, 2 underground floors, and 14 floors above plus or minus zero. , including 4 floors of podium. The building is approximately 50m high. The first floor above ground is for hotel lobby, banquet hall and business, the second floor is for business and catering, the third floor is for business, catering and sports club, and the fourth floor is for function hall, banquet office and wedding banquet hall.

This project covers a large area, has a lot of groundwater, and has serious quicksand phenomena. Since it is a hotel project, there are many subcontracting units and the construction period is tight. During the construction process, each subcontracting unit needs to intersperse construction. Coordination is relatively difficult; furthermore, due to design reasons, drawings change frequently, the project volume increases greatly, and the approval time for finalized pricing materials and drawings is too long, which to a certain extent increases the difficulty of construction schedule control.

2. The construction period stipulated in the contract

The specific start time stipulated in this project contract shall be based on the construction report, and the total construction period is 529 days. The actual start date indicated in the construction report is October 28, 2009. If calculated based on the total construction period stipulated in the contract, the final completion date will be April 9, 20XX.

3. Construction delays of this project since the start of the project

Based on the principle of seeking truth from facts, we now list the major construction delays that have occurred since the start of the project and are not caused by our reasons. The event analysis is as follows:

(1) Basic value: less than 0.00: The planned completion time according to the contract is January 15, 20XX, and the actual completion time is May 1, 20XX, which is 105% later than the contract time. Days, the reasons are as follows:

1. Although our company entered the site on October 28, 2009, the site did not actually have the conditions to start full-scale construction at this time. The foundation pit excavation of the foundation company was finally completed on January 20, 20XX. All construction of the engineering piles has not been completed, and the third-party inspection of the engineering piles has not yet been carried out. (The final inspection was completed on January 22, 20XX. At this time The pile foundation project has not yet passed the quality inspection station acceptance). Due to the foundation company, our company was unable to carry out the overall construction of the base plate, which caused the foundation project to be seriously delayed. Due to this reason, the construction period was directly affected by 50 days.

2. When our company was constructing the cap platform, the water-stop curtain constructed in the early stage did not play a role in water-stopping, resulting in a large amount of water accumulation in the foundation pit. Moreover, the bottom of the foundation pit of this project is a sandy soil layer, which causes a large amount of quicksand to appear around and at the bottom of the foundation pit, making it impossible to construct the cap platform according to the original plan. Although our company successfully solved this problem by using caisson construction technology after consultation with your company, this incident had a great impact on our company's construction period, which directly affected the construction period by 45 days.

3. Since our company received the first set of construction drawings from the design unit on October 16, 2009, it has been undergoing frequent design modifications, causing trouble and delays in the entire construction process. Especially after the design unit modification is completed. However, the civil air defense design unit failed to make corresponding changes and modifications in time, and basically constructed the work based on the electronic version, which resulted in our company being unable to carry out simultaneous construction of the civil air defense part. As a result, the civil air defense construction in the basement could not proceed smoothly, which directly affected the construction period of the project and delayed it by 10 days. (For details, please refer to the engineering instruction LNTD/LOTD/PM/I-013.017.018.019.021.022.024.025.026.027.029.030.032.036.037.039.041.042.043.044)

(2) Projects below four floors of group buildings : The planned completion time according to the contract is March 16, 20XX, and the actual completion time is June 10, 20XX.

1. Due to frequent changes in the drawing design, our company's construction material preparation could not be carried out normally, and some parts even caused rework, resulting in a 10-day delay in the construction period. (See Design Change Engineering Instructions

LNTD/LOTD/PM/I-046.047.050.053.057.058.060.061.063.065.066.067.068.069.070.072.073.074.076.077.078)

2. In order to speed up the construction, our company made special personnel arrangements and arrangements for the masonry project, that is, a masonry team was arranged for each floor of the podium part. However, when the podium masonry was completed for about 70 seconds, your company The company issued a construction suspension order on July 16, 20XX, requiring the suspension of construction on some walls of the podium building (later, it did not issue a contact order until August 4, 20XX, requiring the resumption of work). During this period, our company suffered a large number of labor losses. Although we tried our best to remedy the situation, we still lost a large number of masonry workers in a short period of time. This incident had a great impact on the construction schedule.

3. Due to your company’s changes and modifications to the masonry part of the podium building, the walls of the podium hotel have been extensively reworked (the blueprint of January 28, 20XX can be compared with the blueprint of June 30, 20XX) , due to this modification and change, the handover of the podium masonry has been seriously delayed, decoration, fine decoration, mechanical and electrical, indoor piping and other projects have been postponed simultaneously, and the acceptance time of the podium has also been postponed accordingly. Although our company is currently working on this part of the project We are actively increasing personnel and rushing to carry out construction on schedule, but it is impossible to eliminate the delay and impact on the final completion time of this project.

(3) Tower structure construction stage: According to the contract, the planned completion time is June 4, 20XX, and the actual completion time is October 21, 20XX.

1. Due to frequent changes in the drawing design, our company's construction material preparation could not be carried out normally, and some parts even caused rework, resulting in a 19-day delay in the construction period. (See Design Change Engineering Instruction LNTD/LOTD/PM/I079.080.081.083.086.088.094.090.095.096.098.099.100.104.105.107.109.

　111.116.119.120.123.126.129.13 4.139.152)

2. Due to the requirements of hotel operators and wall sound insulation, the interior walls of apartments and hotels have brought great trouble to the arrangement and work deployment of our wall-laying staff, especially those of Thirteen, and Ten Modifications to the four-story interior wall masonry were delayed for nearly a month. Due to this modification and change, the handover of the tower's masonry has been severely delayed, and the decoration, fine decoration, mechanical and electrical, indoor piping and other projects have been postponed at the same time.

Due to the above-mentioned reasons, the construction period of the project was delayed during the construction stages of the foundation, podium and tower structures. Despite the efforts of our company, the construction period was still delayed by 134 days.

(4) Fine decoration construction and completion acceptance stage: According to the contract plan, the completion time is April 9, 20XX, and the actual completion time is April 22, 20XX (April 22 is the completion date The completion report time is December 30, 20XX.

1. Due to the additional plastering work on the inner wall of the tower, the construction period will be extended by 30 days. Due to this modification and change, the fine decoration project of the tower has been postponed.

2. Due to your company’s reasons, the entry time of the Zhongsan and Oriental fine decoration subcontractors is 135 days behind the arrival of the apartment fine decoration units. The entrance time of the apartment fine decoration units is November 15, 20XX. The arrival time of the hotel's finely decorated units is April 1, 20XX.

3. Due to the government-mandated shutdown of the construction site due to the Asian Games, although a small number of workers in some types of work in our company secretly worked indoors, the construction period was still affected for at least 7 days. (For details, please refer to the supervision engineer’s notice ZGJL/LOTD-064)

4. Your company’s professional subcontracting unit was determined late, the material finalization time was too long, and the materials supplied by your company were often Delay, the review of decoration drawings took too long, resulting in a 50-day delay in the construction period.

5. Due to the frequent design modifications after your company determined the hotel operator, the construction period of each professional subcontracting unit was delayed by 22 days. (See Design Change Engineering Instructions for details)

This project was delayed for 378 days based on the contract period*** from the beginning to the completion.

IV. Conclusion

To sum up, although our company encountered various difficulties during the construction process, we have always maintained good communication and our company will do our best at all costs. , using various measures, efforts to rush construction have not been relaxed. A lot of work was also done for the final acceptance of the project, which advanced the time for the trial operation of the hotel.

Based on the principle of seeking truth from facts and win-win cooperation, I hope your company can investigate carefully. Our company would like to apply for an extension of the construction period of this project until the actual completion date of this project is April 22, 20XX. We hope that your company will approve it.

Our company also believes that this move will further increase mutual trust between the two parties and create a good atmosphere for further cooperation between you and us in the future. Construction period extension application report 3
