El� HILLS <br />MEMORANDUM <br />DATE: November 15, 2010 <br />TO: Honorable Mayor and City Council Members <br />Patrick Klaers, City Administrator <br />FROM: Matt Woodruff, Civil Engineer <br />SUBJECT: Lexington Avenue Sidewalk & Trail Project — Payment #1 <br />Background <br />The City of Arden Hills awarded North Valley, Inc., of Nowthen, Minnesota, the <br />Lexington Avenue Sidewalk and Trail Proj ect on September 13, 2010, for a total contract <br />amount of $90,011.62. <br />Discussion <br />This pay request includes work completed through November 5, 2010. The payment is <br />for $ 82,427.17 and includes concrete sidewalk installation, pedestrian curb ramps, <br />bituminous trail reclamation, bituminous paving, and all associated restoration. <br />This pay request also includes Change Order # 1 which is for payment to the contractor <br />for excavation of additional topsoil material. The quantity originally estimated for the <br />sidewalk was based on an 8" excavation depth. However, during construction it was <br />discovered that below the 8" excavation depth there was additional topsoil material that <br />required excavation, removal, and backfilling with a suitable material for the sidewalk <br />base. <br />Change Order # 1 also includes modifications to the contract for final restoration. The <br />original contract specified that all disturbed areas be restored with topsoil and sod. Due to <br />the time of year, City staff consulted with the contractor and determined that hydro- <br />seeding would be a more effecti�e means of restoration since the sod would likely not <br />survive the winter months and grow next spring. Hydro-seeding is a more cost-effective <br />approach to restoring the small disturbed areas along the new sidewalk and trail. Since <br />hydro-seeding was used in lieu of sod and is less expensive, the net effect of Change <br />Order # 1 represents a cost savings of $4,518.48 to the original contract price. <br />City Council Meeting <br />\�Metro-inet\ardenhills�Admin\Council�Agendas & Packet Information�2010\ 11-15-10 Special Mtg\ 11-15- <br />10Memo_Lexington-Sidewalk_Payment# 1.doc <br />Page 1 of 2 <br />
