Guangzhou Guangjun Engineering Supervision Co., Ltd.:

The Fuqiang Road (Beijiang Road to Renmin West Road) road constructed by our company The project officially started on April 9, 2010, and the planned completion time is October 9, 2011. The total construction period of the project contract is 548 calendar days.

However, due to delays in construction due to land acquisition and demolition, issues left over from demolition, changes in construction drawings, Haizai Nullah project and weather factors, etc., the project cannot be completed as required. We hereby apply to your company for an extension of the project. The construction period and specific details are as follows:

1. Land acquisition and demolition issues

Overall construction progress plan CFG pile soft foundation treatment plan construction time is from March 1, 2010 to December 31, 2010 day, and the total time is 305 days (the prerequisite is that all ground structures within the construction scope must be demolished, otherwise the construction period will be postponed), but since the project will be acquired in three stages: the first time will be K1+080 on March 26, 2010~ Land acquisition was carried out on section K1+880, the second land acquisition was carried out on section K560~K1+080 on August 10, 2010, and the third time on section K000~K560 on April 19, 2011 (including K0 +000~K160 section was delivered for use on July 10, 2011), so our construction unit must carry out construction in two phases. The first phase, K560~K1+880, was completed on April 12, 2010 - January 2011. Completed on May 1,

The second phase K090~K560 was completed from May 4, 2011 to August 12, 2011, with a total of 487 days, and 123 days were caused during this period. The machinery was stagnant and the next step of construction could not be carried out, resulting in a total construction period delay of ***123 days (for details, please see the attached construction team progress plan horizontal chart and CFG pile on-site construction engineering quantity confirmation form).

2. Issues left after land acquisition

This project will complete the right asphalt pavement of K560~K1+880 before February 28, 2011, and will be carried out on April 19, 2011 After the land acquisition for the K000~K560 section and the land delivery in two phases, there are still many unresolved issues:

1. The first K160~K560 section was completed in April 2011 The land was handed over on the 19th. The main problems are that there are 4 residential buildings in the right panel of K460~K500 that have not been expropriated and demolished (two of them are on the main driveway), and there are 4 residential buildings in the left panel of K460~K500. Two residential buildings have not been requisitioned and demolished, and one communication wire at K480 has not been relocated. Due to the above problems, soft foundation treatment and drainage engineering construction cannot be carried out, resulting in a delay of ***30 days (for details, see the attached construction unit work contact sheet 015 , Report on problems existing in the Fuqiang Road (Beijiang Road to Renmin West Road) road project, project regular meeting weekly report No. 55 to No. 70).

2. The second land delivery for the K000~K160 section was on July 10, 2011. The main problems are: the land for the trees (greening) in the K000~K030 section has not been acquired. Relocation; the chicken farm on the left side of K030~K080 has not been relocated; several graves in the K080~K180 section have not been relocated; there is 1 high-voltage line and 1 household wire (weak current) at K170; The left real estate development plots of K060~K120 have not been requisitioned and demolished. Due to the above problems, construction cannot be carried out, resulting in a delay of ***35 days (for details, please see the attached construction unit work contact sheet 014, about Fuqiang Road (Beijiang Road to Renmin West Road) road project problem report, project regular meeting weekly report 55th to 70th period).

3. The problem of construction drawing changes

Due to the frequent changes of construction drawings in this project, the existing construction drawings and the original bidding drawings have changed greatly, resulting in many construction drawings during the construction process. After the problem and the project was scrapped

Repeated construction caused a delay of ***184 days (for details, please see the attached Fuqiang Road Change (Visa) Summary Table).

4. Issues with the Haizai Nullah Renovation Project

The Haizai Nullah Renovation Project is located on the east side of the road project on Fuqiang Road (Beijiang Road to Renmin West Road) (specific station number: K1+200 ~K1+880 (left panel), construction officially started on August 15, 2011. Since the left side of Fuqiang Road K1+260~K1+880 must wait for the completion of the Haizai Nullah retaining wall project before the construction of rainwater pipes, roadbed projects and pavement projects can be carried out, resulting in a delay of ***30 days (see the attachment Fuqiang Road Road Project for details K1+200~K1+880 construction drawing design).

5. Weather factors

Due to the rainy season weather after the Spring Festival in Qingyuan City, the construction period was delayed by ***105 days (see the attached construction monthly report for details).

Based on the above factors, the construction period has been delayed by ***507 days in total.

XXXXXXXXXXXXXXXXXXXXXXXXXXX Project XXXXXXXXXXXXX construction period extension application report

p>

XXXXXXXXX and XXXXXXXX Supervision Consulting Co., Ltd.:

The total number of XXXXXXXXXXXXXX constructed by us is 9195. The original planned construction period is from March 13, 2013 to June 12, 2013. ; We officially started construction on March 22, 2013. As of June 5, 2013, a total of 5,040 gravel piles have been completed, and 4,155 have not yet been completed.

After my company’s project department entered the construction site on March 1 and organized the construction, the following issues affected our company’s normal construction and progress plan for the project:

1. Influence of site factors:

(1) Our company successively entered the site from March 4 to March 13, 2013 to install 4 sets of pile driver equipment. However, due to the leveling work of the construction site not yet completed, the construction It is difficult to carry out; after basically completing the leveling work of the underground platform on March 21, 2013, we officially started construction on March 22;

(2) Because the construction site of the project is divided into multiple Platform, it is difficult to organize effective construction according to the original construction plan and construction progress plan; according to the on-site construction conditions, after three-party discussions, the construction method was determined as: leveling and construction at the same time, step by step; but this also creates a problem for our construction This brings great difficulties, which also increases the difficulty of our construction management and causes many losses caused by delayed work. Among them, from March 5, 2013 to March 21, 2013, the construction party carried out site leveling work on the underground platform of the construction site; from April 24, 2013 to May 6, 2013, the construction party carried out site leveling work on the construction site

The No. 2 area of ??the upper platform is undergoing leveling work; from May 23, 2013 to May 29, 2013, the builder conducted site leveling work in the No. 1 area of ??the upper platform; during the site leveling period, all units were shut down and waiting. To this day, there is no construction area between the upper platform and the lower platform on the site, and the site leveling work has not yet been completed.

(3) Due to the poor overall construction plane conditions of the construction site, soft soil and deep depression in some areas, this has brought great difficulties and serious safety hazards to the operation of our construction machinery, which has greatly Slowed down the construction progress of the project.

2. Influence of weather factors: As we enter the rainy season, the rainy weather makes it difficult for us to carry out normal construction. Since the official start of construction, the rainy weather has been on the 15th.

3. Impact of power outage factors: Due to power outage at the construction site, the construction unit was unable to work; among them, there were one-day power outages on April 18, May 14, and May 15 respectively;

In order to ensure the construction period, at the request of Party A, we added a pile driver to the construction site on May 1, 2013. After completing the construction of Upper Platform Area 2, due to the current construction of Upper Platform Area 1 The district could not place five pile drivers for construction at the same time, so one pile driver was evacuated from the construction site on June 1. This has also had a great impact on the construction progress of the project.

In view of the above situation and comprehensive consideration of the later construction, we have also actively taken corresponding measures and adjusted the original construction plan to plant as many trees as possible in order to speed up the construction of the project as much as possible. schedule. However, in order to ensure the engineering quality and construction safety of the project, we have specifically applied to your company to extend the effective period of the project by 38 days and postpone the completion date of the project to July 20, 2013. Please give your company leadership approval. Thank you very much for your support of our company's work.

Application report for project extension

The general contracting construction project of Foshan Lingnan Tiandi LOT-D apartment hotel project undertaken by our company. 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 drifting sand phenomena. Because 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 fixed-price materials and drawings is too long, which increases the difficulty of construction schedule control to a certain extent.

2. Construction period stipulated in the contract

This project contract stipulates that the specific start time will 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. Based on the total construction period stipulated in the contract, the final completion date is April 9, 2011.

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, 2010, and the actual completion time is May 1, 2010, which is 105 months 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, 2010. 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, 2010. 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 floor, which caused the foundation project to be seriously delayed. This reason directly affected the construction period by 50 days.

2. When our company was constructing the cap, the water-stop curtain constructed in the early stage did not play a role in stopping water, 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 : According to the contract, the completion time was March 16, 2010, and the actual completion time was June 10, 2010.

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 work, our company has made special personnel arrangements and arrangements for the masonry project, that is, a masonry team is arranged for each floor of the podium part. However, when about 70% of the podium masonry is completed, Your company issued a construction suspension order on July 16, 2010, requiring the suspension of construction on some walls of the podium building (it was not until August 4, 2010 that you issued a contact order requesting the resumption of work). During this period, our company suffered a large number of lost workers. 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, 2010 and the blueprint of June 30, 2010 can be compared for reference) , 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 construct the project on schedule, but the delay and impact on the final completion time of this project cannot be eliminated.'

(3) Tower structure construction stage: According to the contract, the completion time was June 4, 2010, and the actual completion time was October 21, 2010.

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 Instructions

34.139.152)

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 Thirteen. and modifications to the fourteenth-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 during the construction stages of the foundation, podium and tower structures, the project schedule was delayed by 134 days despite our company's efforts.

(4) Fine decoration construction and completion acceptance stage: According to the contract plan, the completion time is April 9, 2011, and the actual completion time is April 22, 2012 (April 22 is the completion date The completion report date is December 30, 2011.

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 arrival time of the Zhongsan and Oriental fine decoration subcontractors lags 135 days behind the arrival of the apartment fine decoration units. The entrance time of the apartment fine decoration units is November 15, 2010. The entry date for the hotel's finely decorated units is April 1, 2011.

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.

4. Conclusion

In summary, although our company encountered various difficulties during the construction process, we have always maintained good communication, and our company has always maintained good communication 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 to the actual completion date of April 22, 2012. 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.

Sincerely!
