[案例]

背景

某堤防除险加固工程依据《堤防和疏浚工程施工合同范本》签订了施工合同，施工内容包括防洪闸及堤防加固。其中经承包人申请、监理单位批准，发包人同意将新闸门的制作及安装由分包单位承担。合同约定：

(1)当实际完成工程量超过工程量清单估算工程量时，其超出工程量清单估算工程量15%以上的部分所造成的延期由发包人承担责任；

(2)工期提前的奖励标准为10000元/天，逾期完工违约金为10000元/天。

经监理单位批准的施工进度计划如下图所示(假定各项工作均衡施工)。

在施工过程中发生了如下事件：

事件1：由于山体滑坡毁坏了运输必经的公路，新闸门比批准的施工进度计划推迟10天运抵现场。

事件2：在C工作中，闸墩部分钢筋安装质量不合格，承包人按监理单位要求进行了返工处理，导致C工作推迟5天完成。

事件3：在D工作中，由于安装新闸门的技术人员未能按时到达施工现场，导致D工作推迟6天完成。

事件4：在G工作中，由于设计变更使堤段填筑的工程量达到工程量清单估算工程量的120%，导致G工作48天完成。

事件5：在F工作中，承包人采取赶工措施，F工作20天完成。

[问题]

根据施工中发生的上述事件，确定该工程的实际完成时间是多少天，以及承包人因工期提前的得到奖励或因逾期支付违约金是多少。

Flight cancellations(取消) and loss of luggage can ruin even the best-planned holiday. The key to a stress-free trip is having a backup plan.

Fly non-stop. The worst problems involve connections, so it is important to take non-stop flights whenever possible. If you do have to make a connection, try to route through a southern city, where snowstorms and de-icing delays will be less likely. Always allow at least two to three hours for flight connections.

Check the weather. Check the weather in your connecting city, not just the arrival and departure city. If your departure flight is cancelled because of weather, you can go home or back to your hotel. Airlines promise to get you on the next available flight, not the next flight. That could be several days later on a sold-out holiday weekend.

Go early. The earlier in the day you fly, the better your chance of getting rebooked the same day after a missed connection. It will also put you ahead of stranded(滞留的) passengers who arrive later.

Rebook immediately. As soon as your flight is delayed or cancelled, get on the phone and rebook your flight instead of waiting at the ticket counter. If your rebooking is delayed, call or ask your travel agent to find a seat on another carrier, and then ask your original carrier to endorse your ticket to the new airline. Airlines are not required to do this but often do. Learn more at www. dot. gov/ airconsumer/ fly-rights.

Ship bags. A few days before your flight, ship suitcases or holiday gifts to your destination by a documented express service. It’s preferable to losing bags because of re-routed flights and sometimes cheaper than paying airline overweight bag fees.

Know your rights. Airlines are not required to compensate passengers for delayed or cancelled flights, but it never hurts to ask for goodwill vouchers(折扣) for meals, taxis or a room.
