ARDEN HILLS CITY COUNCIL - OCTOBER 13, 1998 9 . MOTION: Councilmember Malone moved and Councilmember Aplikowski seconded a motion to approve Pay Estimate #6 for Lametti & Sons, Inc. of Hugo, Minnesota in the anlount of $130,095.64. The motion carried unanimously (5-0). D. Change Order #1, Sandeen Road, 1998 Street Reconstruction Mr. Brown indicated Change Order #1 includes work items associated with full milling and re- paving of Sandeen Road. The contractor performed milling on the roadway, per the contract, to prepare for the overlay and constructed approximately 300 feet of concrete curb to improve the drainage of the roadway. During this work, it became apparent that a significant portion of the remaining bituminous had been severely damaged by the associated construction truck traffic and edge milling that had been performed. In lieu of constructing extensive patching prior to the scheduled overlay, the City Engineer determined tllat the best final project for the City would include the reclamation of the remaining bituminous surfacing followed by minor grading of the existing base and paving with three inches of bituminous instead of the two-inch overlay. The Change Order reflects negotiated prices for the reclamation work and an additional quantity for the bituminous wear course at the existing contract dollar amount. Mr. Brown advised the City Engineer recommends approval of Change Order #1 thereby increasing the contract amount by $10,602.70 to a total of$689,959.39. Mayor Probst asked Mr. Stafford ifhe concurs with the recommendation. Mr. Stafford stated he . does.

Authorization to Advertise for Bids, Lift Station #3 Mr. Stafford indicated the City currently has 14 sanitary sewer lift stations. Eight of the stations were installed in the early 1960's and are of the type where pumps, valves, and the control panels are mounted inside a 1 O-foot diameter by I 0- foot high steel cylinder which sits up to 30- feet below the surface. Access to the station is provided by a 3-foot steel tube, rising from the top of the station, to 2 feet above tlle surface. Entering the station requires Confined Space Training and a Confined Space Entry Permit. Any entry also requires a stand-by person to remain on the surface in case a problem develops, such as the entering person being overcome by fumes. Mr. Stafford explained Lift Station #3 is located on Lake Johanna Boulevard west of Siems Court and is one of the eight stations described. Public Works has budgeted $60,000 to convert this station to an up-to-date type in 1998. Staff also included $60,000 in the CIP budget every other year from 1998 on, to convert the remaining seven stations. The converted lift stations will be of the submersible type. This type of station features a 6-foot to 10-foot diameter concrete . manhole with a 3-foot by 4-foot access hatch at ground level. Submersible pumps are mounted in the manhole on tracks which allow the pumps to be hoisted to the surface for maintenance and repair. Control panels are also at the surface, mounted on a cabinet, eliminating the need for dehumidifiers, sump pumps and most confined space entries.
