<br /> Fax: 612.64,.9'46 RE: PROPOSED LIFT STATION NO.6 UPGRADE
<br /> Dear Mr. Stafford: I
<br /> As requested, we have reviewed the proposals submitted for the referenced project, and I
<br /> have made a few lelephone calls to clarify some questions. Proposals were received from
<br /> Tri-State Pump and Equipment, Waldor Pump, and Quality Flow Systems.
<br /> The Tri-State submittal proposed using Myers, submersible, explosion proof, 5 Hp pumps I
<br /> and a basic undefined control panel. The proposal did not include excavation costs, gate
<br /> CV~L ENGIN::\;;'<G valves, electrical work, restoration, or debris removal. Bypass pump rental was listed as I
<br /> EW:;ONMENTAL an extra $1,200 to the base proposed price of $16,928. The lack of the excavation and
<br /> MuNICIPAL electrical costs make it difficult to compare this proposal with the others on a cost basis.
<br /> P:....i..~lN!NG The total proposed cost of $18,128 does not include potentially significant costs for ..
<br /> SCUD 'tIAS"~ subcontractors to install the new cover slab and wire the electrical controls,
<br /> S7RIX~lJAL
<br /> 5J,'/~"(:~.G The Waldor Pump submittal proposed using Flygt, submersible, non-explosion proof, 3 I
<br /> fRAF::C Hp pumps and a basic USEMCO control panel. The proposal quoted $12,771. 48 for
<br /> T.~A~jS?OR;,~ i:QN equipment, $9,720 for labor, and listed potential options of stainless steel chain for $250
<br /> and explosion proof pumps for $600. The proposal did not specifically list check valves 1
<br /> E _:::~KI CALl ,',lEe,.. Ai\liC t..:. but Mr. Goehring of Waldor Pump indicated that they would be provided. Mr. Goehring
<br /> :\.G;"c:~".G anticipated installation of the gate valves inside the wet well structure, so excavation for
<br /> ''""','J:..:: I
<br /> ;;Cw:~ DjSFL3YiO~. outside installation would be an extra cost. The proposal did not include site restoration.
<br /> S("'C:A With the stainless steel chain and the explosion proof pump, the total price of the Waldor
<br /> 5'!$TE\\ CON~ROLS proposal would be $23,341.48. I
<br /> The Quality Flow submittal proposed using KSB, submersible, explosion proof, 3.4 Hp
<br /> pumps and a basic Consolidated control panel. The proposal quoted $14,164.50 for I
<br /> equipment, $9,380.00 for labor, and listed a potential savings of $2,000 if the restoration
<br /> work were completed by the City. The proposal included a master electrician and permits
<br /> to complete the electrical portions of the project. Stainless steel lifting chains were not I
<br /> included, but Mr. Bill Meline of Quality Flow indicated that they could be added for about
<br /> $250. Mr. Meline also indicated that they had anticipated placing the gate valves inside I
<br /> OFFICES IN: the structure so excavation for outside installation would be an extra cost. To compare the
<br /> quoted price from Quality Flow with the Waldor price, the credit for restoration by the
<br /> MINNEAPOLIS City should be deducted and the price for the stainless steel chain should be added. The ..
<br /> PRIOR lAKE comparable price becomes $21,794.50.
