4 ROSEMOUNT
City Council Meeting: April 4, 2006
BACKGROUND:
CITY COUNCIL
EXECUTIVE SUMMARY
On January 17, 2005 the Rosemount City Council authorized the preparation of plans and specifications
for the 2006 Pavement Management Project This project has been designated as City Project No. 396
At this time, the plans and specifications are complete and copies are on file in the Engineering
Department. A bnef review of the proposed improvements follows:
1. LOCATION
The project is located m the southwest portion of the City of Rosemount. Streets included in this project
are located south of Dodd Boulevard, west of Chippendale Avenue, north of 150 Street West (CSAH 42),
and east of Colorado Avenue (property line 1300 feet west of Chippendale Avenue).
2. PROPOSED STREET IMPROVEMENTS
Each street within the 2006 Pavement Management Project has reached a significant level of deterioration
in its quality and performance. As part of the City of Rosemount's Pavement Management Program, each
street or area of streets is to receive the appropriate improvement to enhance the design strength of the
roadway and extend the useful hfe of each roadway Two separate improvements are proposed for the
streets designated m the 2006 Pavement Management Project.
The area of streets within the Btoback 10` Addition, including Chrome Avenue, Chrysler Avenue,
Cimarron Avenue, 146` Street West, and 147 Street West, is proposed to have full depth pavement
rehabilitation Since the existing public utility infrastructure (sanitary sewer, water man, and storm sewer)
are all in place and in good working condition, and the existing concrete curb and gutter has not
experienced significant cracking or settlement, it is proposed that these streets receive pavement
rehabilitation m the form of pavement reclamation.
The area of streets within the Edwin Rahn's 1" 2n and 3` Additions, including Cimarron Avenue, Chorley
Avenue, 148'" Street West, Upper 148` Street West, 149` Street West, and Upper 149` Street West, will
receive a full reconstruction to mclude the removal of the existing bituminous surface and all existing curb
and gutter.

3. STORM SEWER
Currently there is storm sewer in the Broback 10` Addition only. Streets within the Edwin Rahn's 1" 2,.d
and 3 Additions do not have an interconnected storm sewer system. The existing catch basins collect
street surface runoff that infiltrates directly into the subgrade of the toadway. The proposed storm sewer
improvements Include the installation of a subsurface collection and conveyance system throughout the
Edwin Rahn's 1 2nd and 3r Additions. This will transport runoff into two existing infiltration basins
located within the project area. One of the infiltration basins is located on the west side of Cimarron
Avenue between 148 Street West and Upper 148 Street West. This basm has an existing storm sewer
outlet. The second drainage basin is located on the south side of Upper 149` Street West between
Cimarron Avenue and Chorley Avenue This basin does not have a storm sewer outlet. A proposed
outlet is to be installed to the south, extending toward 150` Street (CSAH 42), where a connection would
be made with the existing storm sewer system within the County right -of -way.
4. SANITARY SEWER
The existing sanitary sewer system within the project is generally found to be m good condition. Some
sanitary sewer manholes within the project area have been installed with excessive casting adjustment
rings Pre -cast manhole sections will be installed on these manholes to reduce the number of adjustment
rings and make manhole access safer for pubhc works personnel
5. WATERMAIN
The water main over the entire project area is still well within its useful life. There are, however, portions
of cast iron pipe (CIP) in the Edwin Rahn's 1 2n and 3 Additions. It is recommended that a leakage
test is performed on the water main m these areas prior to construction to determuie if there are any pre-
existing leaks or weak joints in the water main. Potential problems would be fixed as part of construction.
All the fire hydrants that do not conform to the current City of Rosemount design standards will be
replaced with new fire hydrants
6 PARK IMPROVEMENTS
Pedestrian ramps adjacent to Chippendale Park located between Upper 148 Street West and 149 Street
West will be replaced to comply with current American Disabihty Act (ADA) standards.

Memorandum
We have completed the final design for the above referenced project and the associated cost
estimate. The Engineer's Opinion of final cost based on the design to be approved by the City
Council is $1,155,600. The estimated project cost presented in the Feasibility Report and at the
public hearing held for this project was $1,090,000. The final estimate represents an increase in
estimated costs of $65,600 (6% of original estimate).
A review of the project design as it has progressed from the feasibility is summarized as follows:
North Side (Broback): The final cost is $12,000 under the Feasibility Report estimate. ($238,500
Feasibility, $226,700 Engineers Estimate)
o Bituminous cost is $20,000 greater (unit price increase)
o Curb and Gutter is 54,000 greater (unit price increase)
o Sanitary Sewer manhole modifications moved to Sanitary Sewer schedule $10,000)
o Remaining differences from final design changes to quantities and industry unit prices
South Side (Edwin Rahn Additions): Cost is $48,000 over the Feasibility Report estimate.
(5658,800 Feasibility, $706,000 Engineer's Estimate)
o Bituminous cost is 532,000 greater (unit price increase)
o Curb and Gutter is $15,000 greater (unit price increase)
o Concrete Driveway Pavement is $36,000 greater (unit pnce increase and quantity change
associated with match points required during final design. ALSO, 90% of driveways in the
area are concrete, which is unusually high)
o Sanitary Sewer manhole modifications and Water Main valve box modifications moved to
Sanitary Sewer and Water Main schedules 516,000)

o Modified plans for removal of bituminous and new class 5 aggregate base to bituminous
pavement reclamation and using recycled bituminous pavement 513,000)
Sanitary Sewer: Cost is $20,000 over the Feasibility Report estimate. ($25,200 Feasibility, $45,300
Engineer's Estimate)
o Additional manhole barrel section repairs after inspection at the request of the City Public
Works Director
o Moved the cost of new castings with the manhole barrel section replacement from the
Surface Improvements category as outlined in the Feasibility Report
Water Main: Cost is $20,000 over the Feasibility Report estimate: ($23,300 Feasibility, $43,000
Engineer's Estimate)
o Added additional hydrant replacements at the request of the City Public Works Director.
o A portion of the cost can be attributed to unit price increases
o Moved the costs of valve box replacements from the Surface Improvement category as
outlined in the Feasibility Report
Storm Sewer: Cost is $10,000 under the Feasibility Report estimate: ($144,200 Feasibility,
$134,600 Engineer's Estimate)
o Reduced necessary storm sewer pipe quantity through final design process
It should be noted that umt price increases as discussed are based on actual bid prices received on
projects bid in February and March. I would like to point out that concrete prices have increased
approximately 20% in the last two months and oil prices continue to increase. Ultimately, the
construction costs will be dependent on the bidding climate and prices that Contractors are
completing the work for, which may vary with geographic locations in the metro area. Bids that are
received for the work will need to be fully evaluated to insure that prices submitted are within
reason and that the City is receiving the best prices for the work.
If you have any questions or concerns regarding the information contained in this memorandum,
please feel free to contact me at (763) 287 -7193.
