Item/Subject: Authorizing Amendvent to Contract with. Wright -Pierce - Meadowbcook
Sewer
Responsible Department: Engineering
Commentary:
The original misign Contract envisioned the design of a separate storm sewer
to carry the atom water from the Meadowbrook Bag to the Nenduskeag Stre
however. during the design process. it was determined to be more feasible in
the long run to design a new sanitary sewer, and to keep the storm water in
the existing s c
This necessitated additional design work. Also, the
original Contract's cope of work did not include the design of the inter-
state crossing, which x111 be made by modifying the existing 24 inch combined
sewer under I-95 by installing a 12 inch sanitary sewer
within the pipe, and
r
by designing and constructing special structures at either end to connect
the sanitary live into the new sanitary sewer.
11pe.origiral Contract did not includeservices during construction. Ic was
decided to do the inspection in-house, but it is felt to be necessary to
utilize the Consultant in limited contract administration, including monthly
meetings, the review of shop drawings, and the preparation of as -built
drawings.
