MEMORANDUM
DATE: November 15, 2010
TO: Honorable Mayor and City Council Members
Patrick Klaers, City Administrator
FROM: Matt Woodruff, Civil Engineer
SUBJECT: Lexington Avenue Sidewalk & Trail Project — Payment #1
Background
The City of Arden Hills awarded North Valley, Inc., of Nowthen, Minnesota, the
Lexington Avenue Sidewalk and Trail Proj ect on September 13, 2010, for a total contract
amount of $90,011.62.
Discussion
This pay request includes work completed through November 5, 2010. The payment is
for $ 82,427.17 and includes concrete sidewalk installation, pedestrian curb ramps,
bituminous trail reclamation, bituminous paving, and all associated restoration.
This pay request also includes Change Order # 1 which is for payment to the contractor
for excavation of additional topsoil material. The quantity originally estimated for the
sidewalk was based on an 8" excavation depth. However, during construction it was
discovered that below the 8" excavation depth there was additional topsoil material that
required excavation, removal, and backfilling with a suitable material for the sidewalk
base.
Change Order # 1 also includes modifications to the contract for final restoration. The
original contract specified that all disturbed areas be restored with topsoil and sod. Due to
the time of year, City staff consulted with the contractor and determined that hydro-
seeding would be a more effecti�e means of restoration since the sod would likely not
survive the winter months and grow next spring. Hydro-seeding is a more cost-effective
approach to restoring the small disturbed areas along the new sidewalk and trail. Since
hydro-seeding was used in lieu of sod and is less expensive, the net effect of Change
Order # 1 represents a cost savings of $4,518.48 to the original contract price.

The work for the proj ect is complete. However, City staff is proposing to retain $4,33 8.27
(S% due to the contractor) over the winter months until Public Works and Engineering
staff can inspect the proj ect in the spring of 2011. At that time, the contractor will correct
any defective work and the contract with North Valley, Inc. will be closed-out.
Financial Implications
This proj ect will be paid for using PIR funds. A portion of the cost for the construction of
the concrete sidewalk will be assessed to Inland Properties.
