Alternate Scenario

Hello,

I came across a situation that required me to look into multiple scenarios for approaching the structure excavation.
This was a traditional lump sum bid-build I submitted a bid for early in 2022.
The short story is that no excavation shoring system was shown on the drawings but there was a small clause that included a performance requirement that was tucked away in the excavation shoring technical specification

"the shoring shall be constructed as substantially watertight such that dewatering inside the shoring system 
does not substantially lower the groundwater table on the outside of the shoring system since lowering of the 
water table on the outside of the shoring system may lead to unacceptable settlements of existing structures and utilities."

The structures comprise 2-27m diameter biosolids storage tanks with a 10m excavation.
The soil conditions would require a massive dewatering system to keep the excavation dry if a traditional open cut excavation is used. Concerns of damaging existing infrastucture + nearby neighbors on wells. Despise the performance clause there was questions as to whether an open cut excavation would be allowed versus a watertight shoring system.

So I created one scenario in Kubla, then duplicated it, renamed, and modified the scenario. The problem is, there are several duplicate phases between the two files. If i had to update one - then i'd have to go update the other. I don't like managing two files so I thought adding another level to the phase tabs on the bottom of the screen would be a solution.


An interesting note, this job had a budget of $20 million.
There was a competitive open bidding process that had a great spread but still way over budget. 
This used to be a one-off in my industry - but it's becoming a much more common!
