MEMORANDUM
TO: Todd Gerhardt, City Manager
FROM: Paul Oehme, Director of Public Works /City Engineer q `
DATE: April 14, 2014 (X�Y,
SUBJ-. Highway 101 Minnesota River Crossing and CSAH 61 Improvements,
City Project No. 13 -04: Approve Extension of Regular Working
Hours and Night Working Hours
PROPOSED MOTION:
"The City Council approves a resolution for extending regular working hours and
approving night construction working hours for the Highway 101 Minnesota River
Crossing and CSAH 61 Improvements Project No. 13 -04.
City Council approval requires a simple majority vote of the City Council present.
On February 24, 2014, the City Council approved a Joint Powers Agreement with
Carver County and approved plans and specifications. Staff discussed briefly the
need for extending working hours for this project to meet the project completion date.
DISCUSSION
The Counties of Carver and Scott, along with the Minnesota Department of
Transportation (MnDOT) and the Cities of Chanhassen and Shakopee have completed
the design for a four -lane river bridge over the Minnesota River that will protect the
traveling public from 100 -year flooding events. In addition to the Highway 101
bridge, the Highway 101 /CSAH 61 (old 212) intersection, known as the "Y"
intersection, will be reconstructed with a roundabout to accommodate future traffic
demands. This design also accommodates a future north leg to the roundabout.
CSAH 61 will also be reconstructed to a 4 -lane design from Bluff Creek Drive to just
east of the Highway 101 /CSAH 61 roundabout. A roundabout is planned at the
intersection of CSAH 61 and Bluff Creek Drive. The intersection at CSAH 61 and
the Highway 101 north leg will still operate with a signal until the alignment up the
bluff is improved. The project will be constructed in both the City limits of
Chanhassen and Shakopee.

WORKING HOURS
To meet the proposed schedule, extended working hours will need to be considered. The City of
Chanhassen's normal working hours are from 7:00 a.m. to 6:00 p.m. Monday through Friday and
Saturday from 9:00 a.m. to 5:00 p.m. with no work on Sundays or legal holidays. The City of
Shakopee's normal working hours are from 7:00 a.m. to 10:00 p.m. Monday through Friday and
between the hours of 9:00 a.m. and 9:00 p.m, on weekends. It is important to have the same working
hours for the project between the two communities. MnDOT feels the project cannot be constructed
within the given completion dates without extension of normal working hours.
MnDOT, Carver County and the City of Shakopee are requesting the City of Chanhassen normal
working hours be Monday through Friday from 6:00 a.m. to 10:00 p.m. and Saturday from 7:00
a.m. to 10:00 p.m. for this project.
The project will require a lot of pile driving for the bridge abutments and retaining walls. Also a
large amount of muck will be removed from the project along with placement of sand backfill. Over
400,000 cubic yards of muck will need to be removed and over 70,000 feet of 12" to 16" diameter
pipes will be installed. For just the 4,100' long bridge, 408 piles are required. The muck operation
will take place in high water table areas which requires the operation to be continuous so the
dewatering operation can be limited. Also, erosion will be limited with continuous operation and the
execution area does not become super saturated.
Night work hours will also need to be considered to complete the muck operation efficiently and to
meet completion dates. Night work was performed on the TH 212 project with few problems. Most
of the muck work is anticipated to take place in the fall and winter. Night work would only include
muck removal operations and paving. It is not anticipated night work will be continuous throughout
the project but will be needed for several continuous weeks during the muck operation work. Few
residential homes are in close proximity to the project.
Night Construction shall be defined as construction between 10:00 p.m. and 6:00 a.m. Monday
through Friday and from 12:00 a.m. to 7:00 a.m. on Saturdays. For the following dates,
July 30, 2014 to August lat, 2014, Night Construction shall be defined as all hours between
5:00 p.m. and 6:00 a.m. On Saturday, August 2, 2014, Night Construction shall be defined as
all hours between 10:00 a.m. to 12:00 a.m. No work shall be allowed on Sundays without
prior written approval from the Engineer.
The City of Shakopee approved the extension of working hours and night working hours at their
April 1, 2014 City Council meeting.
The proposed requirements for night work are as follows:
• For Night Construction, the Contractor shall be prohibited from performing the following
activities: pile driving /removal, concrete pavement demolition, sawing for pavement
removal, crushing operations, and jack - hammering. Any deviation from the hours that
these activities are prohibited from occurring must be approved by the Engineer.

The Contractor shall have a supervisor on site during Night Construction that has completed
the "MnDOT Noise Mitigation for Night Construction" training in the five years prior to the
start date of this Contract and shall be on file as having completed the training with the
Department. This training is free of charge, approximately 30 minutes in length, and can be
found online at http: / /www. dot. state. nm. us /onlineleaming /construction/noisemitigation. The
nighttime supervisor's name and a copy of his/her certification shall be furnished to the
Engineer prior to Night Construction.
For Night Construction, the following shall be required of the Contractor:
• Notify all sensitive areas of the proposed Night Construction. Notification of the type,
location, and duration of the work shall be made in writing no later than five calendar days
prior to beginning the work. Provide a copy of the notification to the Engineer and the City.
• Provide a contact person who is on site to ensure that any issues related to Night
Construction are immediately addressed.
• Equipment shall have OSHA approved ambient, sound - sensing backup alarms or, as an
alternative, an observer may be utilized in accordance with OSHA standards.
• Allow for equipment to turn - around in lieu of backing up (this includes equipment
entering /exiting the project).
• Construct temporary noise mitigation enclosures or curtains around stationary equipment
(e.g., generators, compressors).
• Tailgates on trucks shall not be slammed. Truck drivers that are unable to control the
tailgates from slamming shall be removed from the project.
• All engines and engine driven equipment used for hauling or construction shall be
equipped with an adequate muffler in constant operation and properly maintained to
prevent excessive or unusual noise.
If the Engineer determines that the Contractor is not in compliance with the Night Construction
requirements, the Engineer will suspend Night Construction until the non - compliant issues are
addressed or the Engineer accepts an action plan from the Contractor that satisfactorily addresses
any non - compliant issues noted.
