Which the foundation is located on mud layer or sea sand layer. Raw geographical elevation is -2.37m, and underground water level is -3.8m.Main house of #1 unit includes Turbine house and bunker bay, axis AD is 52.6m, axis 09 is 91m. The excavation cushion bottom elevation for foundation of main house are -4.1m、-5.1m、-6.1m、-8.4m, the excavation cushion bottom elevation for turbine house foundation is 9.4m, the bunker bay cushion bottom elevation is -6.1m.As for elevation of some foundation is below underground water level, and excavation is deep, it is required to stress on dewatering for deep foundation pit and slop reinforcement to ensure the safety construction.2 Reference Standards and Codes Unified Standard for Constructional Quality Acceptance of Building Engineering（GB 50300-2001） Code for Acceptance of Constructional Quality of Building Foundation (GB 502022002) Code for Engineering Surveying（GB 50026-2007）3 Construction Preparation3.1 Technique PreparationPrepare, review and approve method statement in accordance with procedures.Prepare ITP in accordance with acceptance standard.Prepare construction start report, reviewed and approved by related departments.Organize related personnel for drawing joint review and technique enclosure, making record and archive.Before start work, perform technique and safety enclosure for constructors.Complete site horizontal control network and leveling point monitoring work according to the surveying control point supplied by construction unit. 3.2 Labor Power PreparationLabor required by this project is as following table:S.N.Type of workQuantityS.N.Type of workQuantity1Site management staff27Excavator driver42HSE Personnel18Piling machine driver23QC Inspector19Other staff154Electrician25Surveyor46Truck driver163.3 Machinery PreparationMachinery and equipments by this project is as following table:S.N.NameTypeQuantity (unit)Remarks1Loader12Hydraulic excavator23Submersible pump2.2kw174Dump truck85LevelATO 3216Total StationNTS 312R+17Piling MachineType 4501For steel sheet piling work3.4 Material PreparationPlastic film：4000 m2；Sand bag：600 m；Scaffoldings：7 t；Fastening：1000 pieces；Water pipes：700m；12m steel sheet piles：160 pieces.All above material shall be traced in the whole construction process, and added if found not enough.3.5 Working Surroundings PreparationWater: lead from Phase 3 steel factory water pipes;Electricity: lead from II cabinet located in the southwest of phase 3 #1 boilerRoad: a concrete road used for transportation loc
