Subject: Proposed Revised Phasing - Temporary Shoring
Dear Mr. Powell
As I briefly discussed in my emailed on 2/19/2018, our engineer has laid out this project including the proposed
detour and required excavations to install the temporary 84" pipe and associated junction box. It appears that
temporary shoring will be required along the existing roadway in order to install the temporary junction box,
and additional temporary shoring (MSE wall) will be required over stage 1 of the culvert to build the detour.
RSA Option 1, presented in the detail sheet attached to this letter shows the anticipated quantities and cost to
the department.
Upon further evaluation of the situation, we believe we have a solution that will mitigate some of the additional
costs, and create a more efficient phasing plan for the project. Included with this letter you will find our
"Proposed Revised Construction Sequence C203984". Our plan is to shift the detour 10ft to the west, to be
offset 60ft from the center line of the existing roadway. By doing this we eliminate the need for temporary
shoring against the existing roadway, and will have enough room to construct the complete culvert in one
stage. Further, by utilizing a temporary pumping operation while we install the temporary pipe in the existing
creek, we will be able to eliminate the temporary junction box, 28' of the temporary 84" pipe and the associated
pipe plugs. More quantity of MSE wall will be required, but at a lower cost than the shoring required in Option
1. I have attached the detail for the added temporary shoring cost (RSA Option 2), as well and the anticipated
savings for the deducted items.
We believe Option 2 is the best course of action, and are anxious to get started on the required submittals. In
addintion, we also request shifting the date of availability by 30 days to April 15th, 2018. We believe this time
will be needed to design, submit and get approval for the shoring required. Please review in detail and let us
know if you have any questions or concerns. We are also happy to meet in person to discuss this.

Sincerely,
Mountain Creek Contractors, Inc.
