Mr. Lee Gustafson
Director of Public Works
City of Hopkins
1010 First Street South
Hopkins, MN 55343
Dear Mr. Gustafson,
Attached please find Change Order #3 for Killmer Electric on City
of Hopkins Project #90-04 CjD. Below is a brief description of
each of these items for your information.
1. Move handholes out of brick paver areas in intersections...This
i tern involves the handholes for the signals located at each
quadrant of each signalized intersection. The original design
showed these handholes being located in the brick paver areas.
Prior to the commencement of construction, RLK Associates reviewed
these locations and found two problems with the planned
installation. First, the handholes would have to have concrete
collars poured around the castings due to the nature of the
handhole material. Secondly, the aesthetic result of a casting in
the bricks would be significant. You directed that these be
installed outside the paver areas. The charge of $9055.05 is for
all conduit and additional wiring required to complete this
installation on the signal systems at 5th, 7th, 8th 9th and 10th
Avenues. .
2. Temporary 11th Street Signal Connection... The plans made no
provision for connection of the signal at 11th Avenue during the
winter between the two phases of this project. Public Works
personnel felt it was important that this signal be operational
during the winter. Therefor, a temporary connection was made at
the total cost of $764.93.
3. Replace defective ballast...One of the ballast kits in a two-
light head was defective. The city furnished Killmer with a new
one, and it was installed, including removal of the defective
parts, for a total cost of $161.86.
4. Install overhead banner cables...Two overhead banner cables,
strung between buildings at the intersections of 9th and 10th, had
to be removed during construction. The City asked Killmer to
reinstall new cables after completion of Phase one, and this was
done at a total cost of $618.87.
5. Refeed lights on 8th Avenue...After disconnection of the feed
point which supplied power to the lights from 8th to 9th, it was
necessary to refeed several lights on the side street. This was
not provided for in the bid documents. This work was complete at
· Civil Engineering · Transportation . Infrastructure Redevelopment
· Landscape Architecture . Construction Management
... \
a total cost of $665.87
6. Feed lights east of 5th... The plan set made no provision or
mention that any consideration would need to be given to the lights
east of 5th Avenue. However, it became necessary through our
construction process to refeed these lights, including a temporary
connection. All work was completed at a total cost of $2268.43.
7 . Additional work in plaza to feed clock tower... The design
documents did not detail the work necessary to feed the clock tower
with the appropriate power supply. The work became much more
involved than originally shown, including the necessity of running
condui t into the Senn building. Not all of this work has been
completed. The work that has been finished comes to a total of
$2136.00.
8. Relocate temporary pole.. .All temporary light poles were
originally located in the tree pit locations as shown on the plans.
However, in one instance the tree pit was moved, at the request of
the owner. To facilitate that move during sidewalk construction,
the temporary pole had to be relocated, at a total cost of $454.88.
9. Relocate existing handhole at 6th and Mainstreet...An existing
handhole on the southwest quadrant of 6th was located in the brick
areas. To keep the project theme consistent, this was relocated at
a total cost of $437.52.
10. Ex:tra work as necessary for addition of node at 6th...After
curb, sidewalk and other items had been completed, the City decided
to, add a node at the northwest corner of 6tl1. Killmer had to
relocate a handhole, add conduit, and repour a light base. This
was done at a total cost of $1143.44.
If you have any further questions on these items please feel free
to call.
Sincerely,
/,,-----;
