Chapter II Construction Deployment 1. Characteristic Analysis According to the requirements of the tender documents, the commencement date of this project is April 2, 27, and the actual construction period is 12 days. Our unit plans to complete it in 96 days, with a short construction period. The organization of traffic will be the biggest difficulty in the construction. Due to the large traffic flow and numerous road intersections in the South Second Ring Road, in order to alleviate the traffic pressure brought by the closed construction, facilitate the traffic of surrounding residential areas and units, achieve civilized construction and reduce the impact on the lives of local residents, our unit plans to construct non-motor vehicle lanes first and then motor vehicle lanes. During the construction of motor vehicle lanes, the traffic flow along the road will be introduced to the intersections nearby, which will greatly improve the requirements for the construction period. This bid section is characterized by heavy engineering tasks, concentrated supply of personnel and materials, more operation surfaces and difficult management, so it is necessary to strengthen the connection between various processes. Second, the section division assumption According to the time limit for a project requirements and the situation and characteristics of the construction site, the project has the conditions of simultaneous construction of multiple working faces, so the project is divided into two operation sections for management. The first operation section: Yingzhou South Road to Yingshang South Road, with the pile number range of K2+848.17 ~ K3+632.392, and the construction range is about 784m；; The second operation section: Yingshang South Road to Shahe Road, the pile number range is K3+632.392 ~ K4+599.467, and the construction range is about 967 m; During the construction period of this standard road, it is planned to adopt a closed construction scheme. During the construction period, the existing pipeline will be reconstructed and the new pipeline will be constructed first, and at the same time, the pavement treatment of non-motor vehicle lanes and the excavation of old roads will be started. Re-construct lime soil and water-stabilized macadam base for non-motor vehicle lanes; Then, the asphalt milling and defect repair of the old motorway road are carried out, and asphalt concrete is added; Finally, paving asphalt concrete for non-motor vehicle lanes. In the process of construction, each working procedure is streamlined to reduce the pressure of each single construction period on the overall construction period, and each construction section is relatively independent and coordinated according to the actual situation, thus improving the overall quality and completing the construction task on time with good quality. Third, the construction team assumes that our company intends to appoint a comrade with rich construction experience and very good organization and coordination ability as the project manager of this project, and each construction section is equipped with a comrade with high construction level and many years of experience in urban road construction as the construction director of each section; In addition, the project department will be equipped with a fully skilled comrade as the project chief engineer. The project department has two road construction teams. Fourth, management objectives 1, quality objectives: one-time acceptance, striving for high-quality projects; 2. Time limit for a project: ensure that all the construction contents within the bidding scope are completed within the 12-day time limit required by the bidding documents. 3. Safety construction goal: the death rate of liability accident is zero; 4, civilized construction goal: strive for Fuyang civilized construction model site. V. Overall construction sequence Assumption In order to speed up the progress of the project, ensure smooth implementation and make full use of the working face that can be constructed, we take two major measures: first, the overall project is phased and the phased objectives are clear; Second, partition construction on the plane. The organizing principle of the construction procedure is to clean up first, then fill in, then underground, then shallow, then main body and then subsidiary, and the construction method of plane segmentation, three-dimensional crossing and multi-discipline parallel synchronous running water is implemented. Vi. pertinence of the project organization and management plan 1. coordinate with relevant departments and try to take diversion measures as far as possible. 2, strictly control the construction vehicles, prohibit mechanical vehicles parked in the driveway. 3. During the construction, the method of closed construction shall be adopted. During the construction, signs shall be set and special personnel shall be assigned to command the vehicles. 4. During construction, weidang shall be set around the construction site, and publicity slogans and construction nameplates shall be written. 5. Construction personnel shall wear work licenses, and all personnel entering the construction area must wear safety helmets. 6, subgrade construction often sprinkler, avoid dust pollution. 7, large machinery construction work as far as possible in the daytime, reduce the night construction noise interference to the surrounding residents. 8, earthwork and material transport vehicles in and out of the site for washing to avoid pollution of urban roads. 9. Site materials shall be piled up at the designated site and neatly stacked. 1, after the completion of each working procedure, clean up the scene in time, make the scene clean and orderly. 11, accurate pay-off measurement, and change hands to retest system. 12, in strict accordance with the mixture ratio construction, ensure the internal and external quality of concrete. 13, organize capable professional team to play, configure enough construction personnel and machines to ensure the quality and time limit for a project. 14, establish a sense of service in advance, do a good job in the protection and management of materials, technical measurement and other work. 15, reasonable arrangement of construction sequence, scientific organization construction. 16. Implement dynamic management, timely adjust the construction strength according to the site, shorten the operation time of each process, do a good job of connecting each process, improve work efficiency and temporary material turnover rate. 17, to carry out labor competition, in order to promote the construction progress.
