《建筑索赔：生产力损失》课程概述 本课程聚焦于建筑行业中一个颇具挑战性的问题：生产力损失。生产力损失的定义是承包商每工时产出低于计划产出，这直接导致承包商的经济损失。因此，有效的建筑成本控制，关键在于能够详细衡量和追踪工时与产量，以便分析数据，找出导致生产力低下的根本原因。 尽管项目现场管理人员普遍知道现场人员未按计划完成工作，项目进度、成本和现金流因此受到影响，但在实际操作中，**无法实时测量生产力，使得在项目结束后，以足够的确定性证明生产力损失变得非常困难。** 生产力损失的计算通常是在项目结束阶段，为准备索赔或要求公平调整而进行的。更复杂的是，**计算生产力损失的方法多种多样，成本专业人士之间对此并无统一的计算标准。** 然而，成本专业人士普遍认同，当项目中有足够、未受影响的数据时，**与未受影响的工作进行比较是首选的衡量方法。** 即使计算出了生产力损失，**建立因果关系也是一个难题。** 承包商往往将生产力损失归咎于业主，并要求赔偿；而业主则常常认为是承包商的低估报价或糟糕的项目管理导致的问题，从而拒绝支付额外的生产力损失补偿。 在这种情况下，**生产力损失的根本原因往往成为业主、承包商和分包商之间争议的焦点。**
Productivity loss,Is defined as a contractor output less than its planned output per work hour of input.The result is a loss of money for a contractor.Therefore, a challenging aspect of construction cost control is measuring and tracking work hours and production in sufficient detail to allow analysis of the data in order to determine the root causes of poor labor productivity, should it occur.Known to field project management staff, that the field crews are not completing work activities as planned, and project schedule, costs and cash flow are suffering as a result.There is no way to measure productivity contemporaneously. Thus, productivity losses can be difficult to prove with the degree of certainty demanded by many owners.Lost productivity is, all too often, calculated at the end of a project during preparation of a claim or request for equitable adjustment.Complicating the issue even more, there are myriad ways to calculate lost productivity.There is no common agreement amongst cost professionals as to how such lost hours should be calculated.There is general agreement among cost professionals that a comparison to unimpacted work on the project is generally preferred when there is sufficient data available.Finally, once lost productivity is calculated, it is still difficult to establish causation.Contractors tend to blame such losses on owners and ask to be compensated.Owners, on the other hand, often blame a bad bid or poor project management and thus deny additional compensation for lost productivity.Given this situation, the root cause of lost productivity is frequently a matter in dispute between owners, contractors and subcontractors.
