Piering on muddy site and under the rain

It is the first time since we accepted the tender in September 2010, we didn't  want to have a progress in our home project/site.

As I saw very muddy on the site, particularly on the holes and then it was raining, then the machine was broken, then another machine was called up..... I really did wish they would cancel piering today.

The below pic showed it was very wet and muddy

The below pic showed we had the second machine to dig the hole as the first one was broken

 However, Fowler's contractor_structural engineer Robert came and measured up all the holes and assessed that the most important factor for good piering is correct level and the muddy is not a matter. I must trust Robert to make our life comfortable.

But I really angry with Fowler as we need  to pay extra $4k piering due to the tank location around the sewer line.  I couldn't understand, in another word, it is really unbelievable  why Fowler did not locate our tank in the front yard or driveway while our front setback is 11 meters. 

Our painful site cost for the tank  is $21k + $4k + crane cost
