SUBJ: Approve Change Order No. 4 to West 78th Street and Downtown Improvement
Project No. 92 -3
Anyone who has been around the City of Chanhassen for the past couple of years probably has
noticed that this downtown improvement project is'earing completion. This project is rather
sizeable with many elements to consider and details toaccomplish. As is common with a project
of this size, there are typically some changes that need to be made in the field as the work is
undertaken, due to circumstances that are not always evident at the time that the project plans
are prepared in the office. In addition, there is always some fine- tuning work that must be done,
particularly as it relates to traffic signal and electrical -type work. Change Order No. 4 to the
West 78th Street and Downtown Improvement Project No. 92 -3, for the most part, represents
fine- tuning type work.
The basic elements f h Or r No. 4 follows:

2. In an effort to maintain the ability to provide Christmas lighting on the boulevard trees,
ground fault (GFI) receptacles were inalled for all of the ornamental light pole bases in
the median areas. However, in order to meet code requirements, junction boxes were also
needed to be installed at each location so that splices could be made which would allow
for a smaller conduit necessary to be able to fit into the light bases.
3. Some additional fine tuning included changing over two boulevard ornamental light poles

to the standard corten poles with shoebox luminaires to maintain consistency on West
78th Street from County Road 17 to Trunk Highway 101. An extra loop detector was
added at the intersection of Laredo Drive and West 78th Street to provide better right turn
actuation and clearing detection, and miscellaneous electrical work which tied together
existing street lighting circuits and provided for conduit - installed wiring at appropriate
locations where direct burial in the past has been a problem.
4. A modular block wall was required around the signal controller cabinet at the intersection
of Laredo Drive to reduce slopes and improve the ability to maintain the boulevard area
around the signal controller cabinet.
Additional sidewalk installation is recommended on Great Plains Boulevard and Market
Boulevard. The City is contracting with Twin Cities & Western Railroad to install the
very much - needed grade crossing mats at the Great Plains Boulevard and Market
Boulevard railroad crossings. These sidewalks are very important segments linking the
downtown pedestrian and bike facilities to the Trunk Highway 5 and City corridor trail
facilities. The walk /trail segments have always been a part of the downtown improvement
plan; however, their installation on previous projects has been delayed until the crossings
on the railroad could be accomplished. The coordinated and appropriate time to complete
this work appears to be now.
6. At each of the newly installed traffic signals, many will notice a rather sizeable aluminum
colored cabinet box which are called controllers. Similar size units are found at the
railroad crossings on Market Boulevard, Great Plains Boulevard, West 78th Street and
Trunk Highway 101 in the downtown area. Addition landscaping is proposed around
these cabinets; however, for access and safety reasons they are not able to be fully
screened. Therefore, it is proposed to paint these cabinets an earth tone green color.
An itemized list for this change order is attached. The total amount of Change Order No. 4 is
$36,294.00. This will yield a revised contract amount of $2,770,012.31.
It is therefore recommended that the City Council approved Change Order No. 4 to the West 78th
Street and Downtown Improvement Project No. 93 -2 in the amount of $36,294.00 yielding a
revised contract amount of $2,770,012.31.

MEMORANDUM

City of Chanhassen '
FROM: David Juliff pa.f
Engineer '
DATE: July 21, 1994
SUBJECT: WEST 78TH STREET ,
CITY PROJECT NO. 213
CHANGE ORDER NO.4 '
As requested, we have drafted Change Order No, 4. Explanations for various items
included in Change Order No, 4 are as follows:
• The signal systems revisions (Revise Signal Systems E and F) are at Laredo and
Market Boulevard. It was discovered (after installation) that for emergency vehicles
heading south on Laredo to West 78th Street, and then west to Market, there is '
insufficient time to activate the EVP at Market Boulevard, These revisions tie the
two signal systems together, so that when the Laredo/West 78th Street EVP is
activated, the EVP at Market Boulevard/West 78th Street is activated as well. '
• The reason for the ornamental lighting junction boxes is that with the added conduit
(for Christmas lighting), the conduit would not fit through the base of the existing ,
ornamental lights. Hence, the junction boxes were added so that splices could be
made in the conduit and only the conduit necessary for the operation of the
individual light would be required to fit through the light base. '
• The "Miscellaneous Electrical Work" is wiring, etc. that Egan -McKay employees '
were contacted by City staff to do. Copies of the invoices are attached for your
records,
The modular block wall 75 square feet) was used to improve the slope t
{ 9 A p e around the
signal controller cabinet at Laredo Drive and West 78th Street as requested.
