某工程的施工合同工期为16周，项目监理机构批准的施工进度计划如图2所示(时间单位：周)。各工作均按匀速施工。施工单位的报价单(部分)见表5。

工程施工到第4周时进行进度检查，发生如下事件。

事件1：A工作已经完成，但由于设计图样局部修改，实际完成的工程量为840m³，工作持续时间未变。

事件2：B工作施工时，遇到异常恶劣的气候，造成施工单位的施工机械损坏和施工人工窝工，损失1万元，实际只完成估算工程量的25%。

事件3：C工作为检验检测配合工作，只完成了估算工程量的20%，施工单位实际发生检验检测配合工作费用5000元。

事件4：施工中发现地下文物，导致D工作尚未开始，造成施工单位自有设备闲置4个台班，台班单价为300元/台班、折旧费为100元/台班。施工单位进行文物现场保护的费用为1200元。

问题：

施工单位是否可以就事件2、4提出费用索赔为什么可以获得的索赔费用是多少

     Why are people interested in eating raw foods or whole foods? One reason is that eating these types

of food reduces the risk of acid accumulation in your body.

     Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we

cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These

enzymes were intended by nature to help us digest the food. When we consume food without these

natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed

into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at

once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it

becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid

into fat and stores it safely away from the organs.

     Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us

when we've had enough to eat; as a result, people often overeat. Processed foods also upset the

digestive cycle. The body will either identify these foods as allergens and then store them safely away

from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream

as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and

nutrients heading for the body's cells. The body's metabolism (新陈代谢) becomes inactive, and the

result is weight gain and obesity.

The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.

     To stop this vicious circle in its tracks, people need to consume food and supplements that will

neutralize the acid already accumulated in body. Eating the right types of raw and whole foods can help.

It's also important to restore your enzyme balance. You need to identify and avoid the foods that cause

acid accumulation and consume the foods that increase enzyme production. If you truly want to change

and help your body heal itself, you need to take an active approach.
