City Council Report 99-145
Approve Engineering Services Change Order - 6th Avenue Storm Sewer Project
Proposed Action.
Staff recommends adoption of the following motion: Move that Council approve
additional enaineerina fees in the amount of $13.500.00 for construction services on
Proiect 97-11. 6th Avenue Storm Sewer proiect.
Overview.
In December, 1997 City Council approved an engineering services agreement for this
project in the amount of $101,100. This agreement was based on an estimated number
of hours of project on-site inspection. Several unforeseen problems led to the need for
additional project inspection time. Also, some additional design effort was needed due
to field conditions which differed from city utility plan information. Staff has negotiated
with the consultant, SEHRCM, on the costs of these additional services and reached
agreement on the requested $13,500.00.

Dear Steve:
Over the past several months we have discussed that the construction administration/inspection
services fees for the 6th Avenue/TH 7 project are greater than originally anticipated in our
Engineering Services Agreement approved by City Council action on December 12, 1997. A number
of factors beyond our control attributed to the additional effort required on our part to deliver a
quality product to the City of Hopkins. The reasons are as follows:
· Discrepancy between City records and the existing s~tary sewer service sizes along 6th
Avenue.
· Gas company cutting through the existing sanitary sewer services along 6th Avenue while
installing new gas main.
· Telephone company concrete conduit and cable locations and the lack of response by the
telephone company.
· Contractor error in storm sewer installation along TH 7.
· Changed field conditions related to soils and water table requiring dewatering by contractor.
· Record plan information showing water main location along TH 7 was in error causing a
redesign of the storm sewer along TH 7.
· Field coordination of types and sizes of retaining walls along 6th Avenue.
