2×600MW燃煤机组烟气脱硫工程安装施工组织设计工程概况及施工范围工程施工中,采用科学先进的管理技术对工程进行施工计划管理,将使工程有计划、有步骤地进行,始终处于受控制状态,能加强对工程的管理和协调,提高整个工程的施工进度和施工质量。在本工程施工中,我方将采用先进的施工管理技术,建立MIS系统,采用P3管理软件进行工程管理,实现办公自动化,将施工记录与数据输入微机,实现信息共享,使整个工程在施工中接受业主方监督、控制和指导。运用P3管理软件可进行工程施工、进度计划等管理,将数据输入微机,通过网络与甲方实现共享,实现对工程的动态跟踪,以便对整个工程进行管理、协调和控制。在施工过程中,我方将成立以项目经理为首的施工调度中心,运用P3管理软件来加强施工调度,协调各方面的关系,严格控制各网络节点的实施。在运用P3管理软件上将派专人负责。1.1.工程施工管理根据工程特点和目前项目进展情况,利用P3进行工程施工管理,在施工过程中,从施工设计(施工图纸和有关资料交付进度)、设备制造(设备图纸资料、设备交付进度)、物资采购进度计划、物资运输和存放、工程施工和调试、质量检验到整套启动试运行均应纳入工程施工管理的进度控制之中,以确保整个工程进度计划的实现。1.2.工程进度计划工程进度计划采用三级进度计划和月计划进行分级管理的大滚动、小流水的动态模式。1.2.1.三级进度计划Ø一级进度计划由业主根据本工程总体要求拟订的工程里程碑进度计划。这也是业主方与承包商签订合同的基本要求。Ø二级进度计划二级进度计划是根据一级进度计划和业主方与承包商签订合同要求,由项目部负责编制的进度计划。二级进度计划是对一级进度计划的分解,以专业工程的阶段目标为指导,分解形成该专业工程的具体实施步骤。二级进度计划要留有余地,利用P3可设计多种方案来分析、比较和选择,以达到满足一级进度计划的要求。最后提交给业主方审核后实施,实现对各专业工程进行实施监控、动态联系。该计划在合同签定后15天内提交给业主方审核批准。Ø三级进度计划sitesscatteredworksurfaceshouldbedistributed.Brickmasonryconstructionismainlydistributedinthefactory,thefactoryworks.8.3.1materialdumpsinmasonryconstructionmaterialsarepiledupinbatchesinthevicinityoftheconstruction,hand-to-mouth,andmaintainacertainreserve.8.3.2supplymortarHZS60concretemixingstationaftermixingwith5Tdumptrucktransporttothesurfaceoftheconstruction.8.3.3masonrymaterialtransporttransport5Ttipperwithgravelandothermaterialstransportedtothesurfaceoftheconstruction.8.48.4masonryconstruction....Stone),canbeusedtosew,butitsamountshallnotexceedtheweightofmasonry10%.Stonemasonry:accordingtothedegreeofsmoothnessoftheworksurfaceisdividedintofinestones,semifinestone,crudestoneandstonewoolinfour.StoneprocessingrequirementsshouldbeconsistentwiththesurfaceGBJ50203-20026th.theprovisionsofarticle3.2.8.4.2sand,gravel(1)sandandgravelqualityshallconformtoSD120-84table2.1.2and2.1.3requirements.Mortarandsmallersandaggregateconcreteused,requireddiameterof0.15~5mm,finenessmodulusfor2.5~3.0,layingstonemortarsand,itsmaximumdiameterisnotmorethan5mm;stonemortarformasonrysand,maximumsizelessthan2.5mm;(2)withtwo-gradedaggregateconcrete,gravelsizefor5~20mmand20~40mm.8.4.3cementandwater(1)masonryengineeringusingcementandmarkingshallcomplywiththetechnicalprovisionsofsection8.4.theprovisionsofparagraph3.1,arrivalofthecementshouldbevariety,grade,dateofstockpilingseparately,wetlumpsofcement,theprohibitionoftheuse.(2)waterqualitystandardsshouldberequired,mixingmortarandsmallaggregateconcrete.Onmixingandcuringofwaterqualitywhenthereisdoubt,mortarstrengthverificationshouldbecarriedout,thecompressivestrengthofthemortarifthewaterisbelowstandard28daysthecompressivestrengthofmortarmadeofwaterbelow90%,thiswatercannotbeused.8.4.4smallaggregateconcreteandcementmortar(1)mixofcementitiousmaterialsmust121
2×600MW燃煤机组烟气脱硫工程安装施工组织设计工程概况及施工范围三级进度计划是各个子任务的进度计划,由各专业工地依据二级进度计划和合同的要求,结合本专业的特点分解编制的周进度计划,该计划细化到每周施工进度计划,以班组为单位,明确表述每周具体的施工计划,投入的人力、机械,完成的工作量。1.1.1.月计划月计划是工程科根据目标计划制订出的执行计划,它是根据进度计划进行过滤、筛选,并结合实际施工情况,在不违背目标计划的基础上适当调整的执行计划。各专业工地根据此月计划编制出本工地的周计划,周计划以班组为单位,明确表述每周具体的施工计划,投入的人力、机械,完成的工作量。,交项目工程科审核。专业工地所属的各班组根据工地的周计划编制本班组的日计划,交专业工地审核确定后实施。1.1.2.三级进度计划和月计划是按周保月、月保年、年保总体计划的原则,进行分级控制,确保工程按期完成。在工程进度编制上细划到各专业项目作业的周进度,并根据里程碑进度,加强跟踪,每周对进度进行更新。将更新后反映的问题反馈到业主方和我方各级主管,以确保施工进度的准点。1.1.3.坚持每周一次的施工调度会制度,在调度会上,检查总结上周工作,布置本周工作计划;解决施工过程中出现的问题;协调物资、设备、材料、机具等问题;检查质量、安全等方面的情况,提出下一步的工作目标。1.2.跟踪控制和动态管理跟踪控制和动态管理是避免计划流于形式和严格执行合同的关键。为了及时发现工程施工进度与目标工程进度的差异,通过网络图和关系图表紧紧抓住各个施工阶段和施工环节,定期对工程施工进度进行跟踪,对工程施工进度与目标工程进度的差异进行分析原因,采取对策,实行动态管理对计划不断进行更新调整,形成新的进度计划。1.3.建立作业编码体系编码体系是使用P3进行项目管理的基础,要靠使用人根据实际工程的需要编制和确定,本工程编码体系应和业主方编码体系一致,或由业主方统一编码,或由项目工程科根据业主方的编码体系策划出适合本工程的编码体系,统一的编码体系是进度计划控制的基础,各部门参照执行。2.信息管理信息管理是指信息的收集、整理与传递,包括文件资料和计划、统计报表。信息管理是基础管理工作,要做到凡事有章可循,凡事有案可查,搞好信息管理工作是整个工程的重要环节。sitesscatteredworksurfaceshouldbedistributed.Brickmasonryconstructionismainlydistributedinthefactory,thefactoryworks.8.3.1materialdumpsinmasonryconstructionmaterialsarepiledupinbatchesinthevicinityoftheconstruction,hand-to-mouth,andmaintainacertainreserve.8.3.2supplymortarHZS60concretemixingstationaftermixingwith5Tdumptrucktransporttothesurfaceoftheconstruction.8.3.3masonrymaterialtransporttransport5Ttipperwithgravelandothermaterialstransportedtothesurfaceoftheconstruction.8.48.4masonryconstruction....Stone),canbeusedtosew,butitsamountshallnotexceedtheweightofmasonry10%.Stonemasonry:accordingtothedegreeofsmoothnessoftheworksurfaceisdividedintofinestones,semifinestone,crudestoneandstonewoolinfour.StoneprocessingrequirementsshouldbeconsistentwiththesurfaceGBJ50203-20026th.theprovisionsofarticle3.2.8.4.2sand,gravel(1)sandandgravelqualityshallconformtoSD120-84table2.1.2and2.1.3requirements.Mortarandsmallersandaggregateconcreteused,requireddiameterof0.15~5mm,finenessmodulusfor2.5~3.0,layingstonemortarsand,itsmaximumdiameterisnotmorethan5mm;stonemortarformasonrysand,maximumsizelessthan2.5mm;(2)withtwo-gradedaggregateconcrete,gravelsizefor5~20mmand20~40mm.8.4.3cementandwater(1)masonryengineeringusingcementandmarkingshallcomplywiththetechnicalprovisionsofsection8.4.theprovisionsofparagraph3.1,arrivalofthecementshouldbevariety,grade,dateofstockpilingseparately,wetlumpsofcement,theprohibitionoftheuse.(2)waterqualitystandardsshouldberequired,mixingmortarandsmallaggregateconcrete.Onmixingandcuringofwaterqualitywhenthereisdoubt,mortarstrengthverificationshouldbecarriedout,thecompressivestrengthofthemortarifthewaterisbelowstandard28daysthecompressivestrengthofmortarmadeofwaterbelow90%,thiswatercannotbeused.8.4.4smallaggregateconcreteandcementmortar(1)mixofcementitiousmaterialsmust121
