[Neighbors] Nob Hill seeks your support on Lead and Coal Aves.

Van,

That said, I should add that the work to implement such a system would
probably involve two City contracts:  One to hire an engineering consultant
to develop the concept of operations and to prepare the construction
plans.  This selection would be made based on qualifications and would most
likely go to a local New Mexico firm.  Then second would be a
price-competitive bid for the Construction contract.  It would most likely
go to a local traffic signal contractor.  The Contractors bidding for the
work would include the equipment price within their bid.  It's not an
insignificant portion of the overall bid price, but the local
Contractor's labor and other materials (wire, concrete, conduit, etc.)
would probably amount to much more.
