新西兰施工论文代写：项目进度

关键路径法是一种很好的项目进度管理方法。它用来计算最短的项目工期，有助于确定进度状态并反映任何原因和滞后。该方法基于计算最早开始，早结束，晚开始晚结束的日期来反映整个项目的所有活动（PMBOK 2013）。此外，任何关键路径上的延迟都会影响整个项目，因此项目经理需要监控关键路径上的所有活动。

挣值管理（EVM）方法用于项目绩效评估，协助项目经理评估过去和目前的工作和下一步的进度计划更新。它提供了一些精确的数据来帮助项目经理做出决定。这些数据是这个项目健康信息的唯一来源。

衡量项目绩效的三个关键因素包括计划价值（PV）、挣值（EV）和实际成本（AC）。根据PMBOK（2013）：

进度差异：SV = EV – PV

成本差异：CV = EV – AC

进度性能指数

成本绩效指数

SV和SPI可以用来度量项目是否超出了预期的进度。CV和CPI表明成本超出预算或低于预算。

考虑到这一情况，项目计划在2年内完成，污染测试是影响项目进度的主要因素。如果以前公司有污染，项目进度将从“许可阶段”推迟，附加费用将被收取。项目发起人、项目经理、项目团队和环保局将参与这项活动。

Critical path method is a good way to manage project schedule. It is used to work out the shortest project duration, help to determine schedule status and reflect any leads and lags. This method based on calculates early start, early finish, late start and late finish dates to reflect all activities in whole project (PMBOK 2013). In addition, any delay on critical path can affect the whole project so project manager need to monitor all the activities that on critical path.

Earned value management (EVM) method is used for measurement of project performance, assist project manager to evaluate the past and present work and update the schedule plan for next step. It provides some precise data to help project manager make decision. That data is the only source of information about this project health.

There are three key factors to measure the project performance including planned value (PV), earned value (EV) and actual cost (AC). According to PMBOK (2013) :

Schedule Variance: SV = EV- PV

Cost Variance: CV = EV- AC

Schedule performance index: SPI = EV/PV

Cost performance index: CPI = EV/AC

SV and SPI are useful for measuring whether a project is ahead of the expect schedule or not. CV and CPI are indicating the cost is over budget or under budget.

Considering this case, where the project is planned to be finished in 2 years, contaminate test the main factor that affects project schedule. If there are any pollutions from previous company, the project schedule would be delayed from ‘permit phase ’and addition cost would be charged. Project sponsor, project manager, project team and EPA will be involved in this activity.
