Good; I have not made any comments to this yet anyways since there wasn’t really a question involved. I’m also
generally of the mind that the contractor should first win the job with what we are proposing, then we can talk about
cost saving ideas. We’re not interested in dealing with every whim a bidder has.

Subject: Joint Free Round CIP Storm Manhole Option - Coppell / West Sandy Lake Road
Improvements:
Dear Sirs,
We are proposing to bid the 9 storm drain manholes as one-piece-joint-free Round Cast-in-Place
on the City of Coppell, "West Sandy Lake Road, Phases 2A & 2B" project that bids on 4/25/13.
Constructing these storm drain manholes as Round Cast-in-Place (in lieu of outdated square
designs) we can install them with greater strength, more watertight, faster completion, and at less
cost. A time tested manhole construction process already updated into the City of Coppell
Sanitary Sewer design specifications.
I've attached NCTCOG 5050 round manhole detail for approval. Also attached is our new 7'
Diameter Manhole procedure video for you to view?
Thank you,
Tim Mayrath
