I'm not sure I understand the need for a temporary solution to this. There is nothing draining through here now. Is this
delaying a critical path item?
I'm concerned that if we place this pipe in here we may be making it more difficult for AT&T to resolve the conflict.
I don't have enough information to support this proposal at this time. I'd be happy to discuss this in detail on Monday.

This solution of utilizing HDPE pipe with a concrete collar at the
transition is acceptable to PacTrust. However, we would obviously defer
to the City for approval of the temporary alternate native for piping
over the existing AT&T duct bank.

Hi guys
I attach a temporary alternative using HDPE pipe at AT&T crossing
location. Also, as the flow line at the existing Box Junction Box is a
little higher than shown on the plans, I had to raise the flow line of
Lat B-5 wye inlet as shown. The sketch shows the adjusted flow lines
from Sta. 0+00.0 to Lat B-5. If this alternative is acceptable, please
disregard the previous ones I sent. Please call Dave Littleton at
214-346-6213 or me if any question
