施工项目工期优化

摘要工程进度的时效性决定了工程工期的目标特征，优化工程工期必须加强工程进度管理，工程进度管理的关键之一在于科学合理的进度计划。探索施工进度计划优化问题具有很强实际意义。本文通过概述国内外进度管理现状、疏理工程进度计划优化的基本原理，以世纪花园进度计划编制及优化实践为对象，详细介绍了其施工进度计划编制的结构分解、工序确定、时间估算、计划编制和时间参数计算过程，针对工期目标要求开展进度计划优化工作，分析了其优化的效果，剖析了盲目压缩工期、资源冲突等问题及其原因，提出了科学压缩工期、资源平衡配置、提供人员素质等改进措施与建议，期望提高工程进度管理的有效性。关键词：施工进度；计划优化；实践问题；对策建议PracticeAnalysisforConstructionScheduleOptimizationAbstractThetimelinessoftheprojectscheduledecidesthetargetcharacteristicsoftheconstructionduration.Theoptimizationoftheprojectdurationmustenhancetheconstructionschedulemanagement.Tomaketheschedulescientificandreasonableisonekeyoftheconstructionschedulemanagement.Explorationoftheconstructionscheduleoptimizationproblemhasastrongpracticalsignificance.Thispaperpresentsthebasicprincipleoftheconstructionmanagementandtoday’sdomesticandforeignprojectscheduleoptimization,CenturyGardenscheduleplanandOptimizationPracticeistheobjectofthispaper.Itintroducesitsconstructionscheduleplanningstructuredecomposition,determination,timeestimation,processplanningandtimeparametercalculationprocess.Accordingtothegoaloftheprojectrequirementstocarryouttheplan’soptimizationwork,thispaperanalyzesitsoptimizationeffect,theproblemsofblindcompressionoftheschedule,resourceconflictsanditscauses,andputforwardscientificcompressedschedule,resourcesbalancedallocation,providespersonnelqualityimprovementmeasuresandsuggestions,expectingtoimprovetheeffectivenessofprojectschedulemanagement.KeyWords：constructionschedule；scheduleoptimization；practiceproblems；countermessuresandsuggestions目录第1章绪论.........................................................11.1选题背景.....................................................11.2研究意义和目的...............................................11.2.1研究意义...................................................................................................11.2.2研究目的...................................................................................................21.3国内外研究概述...............................................21.3.1国内研究概述...........................................................................................21.3.2国外研究概述...........................................................................................41.4研究基本内容.................................................71.5技术路线.....................................................7第2章施工进度计划优化基本原理概述.................................92.1施工进度计划优化内涵及原则...................................92.1.1内涵...........................................................................................................92.1.2原则...........................................................................................................92.2进度计划优化基本方式........................................102.2.1工期优化.................................................................................................102.2.2费用优化.................................................................................................102.2.3资源优化.................................................................................................11第3章世纪花园进度计划编制及优化实践..............................123.1工程概括....................................................123.1.1项目概况.................................................................................................123.1.2承包商概况.............................................................................................123.2承包商组织结构与制度........................................133.2.1组织结构.................................................................................................133.2.2施工进度计划要求.................................................................................133.3施工进度计划编制过程及分析..................................143.3.1施工结构分解.........................................................................................143.3.2施工顺序确定.........................................................................................163.3.3各分项工程持续时间估计.....................................................................173.3.4初步网络进度计划编制.........................................................................183.3.5时间参数的计算.....................................................................................193.4进度计划优化过程............................................213.5优化效果....................................................24第4章世纪花园进度计划优化问题分析及改进对策......................264.1进度计划优化主要问题........................................264.1.1C工程盲目压缩工期..............................................................................264.1.2D与G发生资源需求冲突......................................................................264.1.3M、P工程工期拖延问题........................................................................264.1.4编制不科学.............................................................................................264.2原因分析....................................................274.2.1C工程盲目压缩工期原因分析..............................................................274.2.2D和G资源供应冲突原因分析..............................................................274.2.3M、P工程工期拖延原因分析.....................................
