MUSA Expansion Project No. 06-05: Approve Change Order #1
REQUESTED ACTION
Approve Change Order #1.
BACKGROUND
On April 10, 2006, the Council approved plans and specifications and authorized
advertisement for bids for the Bluff Creek Boulevard Improvements. The
improvements included as a part of this project were as follows:
. Construction of Bluff Creek Boulevard from Audubon Road to approximately
4,100 feet to the east.
. Construction of turn lanes and a traffic signal at the Audubon Road and Bluff
Creek Boulevard intersection.
. Installation of trunk watermain along Bluff Creek Boulevard.
. Installation of trunk sanitary sewer along Bluff Creek Boulevard.
. Construction of storm sewer and ponding improvements along Bluff Creek
Boulevard.
. Construction of retaining walls in the vicinity of the Bluff Creek crossing.
. Installation of street lighting and landscaping along Bluff Creek Boulevard.
r
On June 2, 2006, bids were open for the project and on June 12, 2006, the City
Council awarded a construction contract for the improvements.
DISCUSSION
The contractor has nearly completed the improvements to the Audubon Road and
Bluff Creek Boulevard for this year. The improvements to the intersection
included widening Audubon Road to construct turn lanes and installation of a
signal. By widening Audubon Road, the boulevard grades increased more then
anticipated next to the pedestrian trail on the west side of Audubon Road. The
trail segment should be lowered to reduce the boulevard grades.
The attached change order is for lowering the trail. The work would include
lowering the trail a maximum of two feet (2'), replacing approximately 550' of

trail, installation of a modular block retaining wall and miscellaneous watermain
work. The right-of-way out side the trail is very narrow. Staff has discussed
obtaining a temporary easement from the property owner adjacent to the work to
grade on his property to reduce the amount of wall needed. However, this
property owner would not grant an easement without an exorbitant fee.
The cost of the change order improvements would mainly be assessed back to the
developers since the work is necessary for the project. The City would be
responsible for 20% of the cost consistent with the cost splits for Audubon Road
and Bluff Creek Boulevard improvements. The City's cost would be from
Municipal State Aid funds.
Staff has reviewed the costs and finds them acceptable. Staff recommends
approval of Change Order #1 at this time.
