Temporary power supply for construction has been solved through providing generator by
8、the contractor as well as temporary water supply has been also connected to the site.3. Construction arrangementConstruction organization managementProject methods will be conducted for the construction and we will establish a Project Department in charge of performing the contract in all respects,
9、organizing, inducting managing, coordinating and controlling the construction. The project Dept. will take scientific management, crack and highly effective team as well as reasonable structure as its principle to form a strong construction team for the works construction, meanwhile, accept the supe
10、rvisions of owner and supervisors so to ensure the time and quality of the construction.A project responsible system will be conducted for all works in respect of production, technology, quality, cost and safety, with dynamic management and optimized combination in system. We intends to take corresp
11、onding measures as follows in the construction organization and arrangement:3.1.1 In order to ensure the completion of the works in time, except preparation of master program, sectional operation program will be worked out based thereon to control the construction progresses of sectional or sub-item
12、 works, organize labors in earnest, arrange overtime work and allocate labors as necessary to the extent that the construction progress is ensured without suspension and holdup in the work, and initiatives of all participates in the construction will be fully given play to, and the construction assi
13、gned us by the owner will be completed on or before the specified time.3.1.2 Stress on planning management, properly work out month, week and day work plans, set up a reliable materials and supporting system to the extent that the supply can be ensured and the transportation meets any requirement.3.
14、1.3 Fully use commercial concrete for the structure of the works, properly coordinate with concrete suppliers, improve planning and allocation to ensure the construction demands, conduct transaction in the commercial concrete management market and conclude and sign contract in relation thereto.3.1.4

16、rected by the Project manager. Functions of all sections (see attached management network of organization structure on the site hereinafter) as follows:Technology section: Jointly review workshop drawings, preparing construction methods, detailing drawing, formwork and reinforcement, implementing co
17、nstruction measurement and sorting out technical data, telling the operation sections for sectional or sub-item works of the detailed requirements, solving the technical issues occurred in the construction and organize the construction in accordance with the workshop drawings, related National Codes
18、, Procedures and regulations.Quality inspection section: Be familiar to construction specifications, procedures and standards for quality inspection, performing quality acceptance work in taking-handing-over of all working operations, inspect and supervise the quality of the materials delivered to t
19、he site and construction quality on the site. Define the quality target of the works and conduct a quality assessment among all sections.Safety inspection section: Be familiar to safety operation procedures and labor protection ordinance, take the responsibility for safety and civilization inspectio
20、n in the construction process and put forward opinions for rectification.Materials section: Shall be familiar to the performance and quality requirements of the materials, prepare materials procurement and supply plans, buy corresponding construction materials in time per required by the works, take
21、 good care of the materials such as storage, positioned stacking etc, timely provide documentation information in respect of the quality of the materials to technology Section.Financial & budget section: properly take the responsibility for examining and calculating the cost for the works, statistic
22、s of the quantity of the works, payment collection, alternation of the construction budget etc.Supporting section: Shall be responsible for living and logistics work, site security, site cleaning and maintaining work.Various operational groups will be set up for organizing labors per trade for the w
23、orks such as carpenter group, steel bender group, scaffolding work group, concrete group, masonry group, installation group etc. to operate under coordination and unified direction.3.1.5 Organization of construction management staffs as Figure 1 hereunder: Figure 1Project director: *Technical manage
