SUBJECT: Lift Station #1 & #12 Improvements - Partial Pay Request#4

Lift Station#I and#12 Improvements were bid to have a contractor install new structures
and piping at each location, remove the old lift station structure and then install new
pumps, control panels and other equipment provided by the City. The City contracted
directly with Electric Pump Company to provide these items for Lift Stations #1 and#12.
The City Council awarded Magney Construction, Inc., Lift Stations #1 and #12
Improvements on April 30, 2012, including the forcemain replacement at Lift Station#12
in the amount of$291,620.00.
Discussion
This fourth pay request is for restoration of the two sites, lowering an existing forcemain,
and reduction of retainage. The total pay request is in the amount of $294,820.00.
Attached is a letter dated October 16, 2012, from Elfering and Associates indicating they
have inspected the work performed and recommending payment.
After retainage reduction to 2% ($5,896.40) is withheld from the payment and previous
payments of $264,404.00, the total due the contractor for Partial Pay Request #4 is
$24,519.60. This project is being totally funded from the Sanitary Sewer Fund.
Council Action Requested

$24,519.60 for Lift Station#1 and#12 Improvements.

RE: LIFT STATION 1 AND 12 IMPROVEMENTS
PARTIAL PAY ESTIMATE#4
Dear Council Members:
Please find attached 3 copies of Partial Pay Estimate No. 4 for the above-referenced
project. As you are aware, the Contractor for the project is Magney Construction, Inc.
The total amount earned by the Contractor on this partial pay estimate is $294,820.00.
The Contractor has submitted a request for the retainage to be reduced to 2%. If this is
approved, subtracting 2% retainage of $5,896.40 and previous payments in the amount
of$264,404.00, the amount due the Contractor is $24,519.60.
This pay estimate includes payment for restoration of the two sites, lowering of an
existing forcemain at lift station 1, and a reduction in the retainage. The lowering of the
existing forcemain was a changed condition in the field due to conflicts that were
identified after excavation of the existing 12-inch watermain in the course of
construction. The watermain was not in a location that was expected prior to
construction and modifications were necessary to avoid conflicts.
We have inspected the work performed by Magney Construction, Inc. and find it to be in
compliance with the plans, specifications, and contract documents. Therefore we would
recommend approval of Partial Pay Estimate No. 4 in the amount of$24,519.60.
If you have any questions regarding this issue please feel free to call.
Sincerely,
ELFERING & ASSOCIATES

Re: Arden Hills Lift Station NO. 1
Kristie,
We are offering the following price quotations for two options to deal with the existing 12" Watermain that
is located between the Wet Well and Valve Vault at Lift Station 1:
A. Lower the Forcemain elevation, between the wet well and the Valve Vault, from 900.5 to 899.
This change involves core drilling three new holes in the wet well at this lower elevation. Plugging the existing
pipe penetrations, adjusting the length of the vertical riser between the pumps and the 90 degree elbow,
lower the bottom elevation of the Valve Vault by adding an 18" riser to the Valve MH and add itional-QXcavation
to install the forcemain beneath the Watermain. _`11
TOTALLUMP SUM PRICE................................................................................. ......$3,200.00 r'
B. Re-route the ermain by ping the el ion approximate 18".
This chan volves expo ' about 20 ft atermain, cuttin pipe and installin degree el s
to dire e pipe down a lower elev 'on, disinfection of pipe.
TL LUMP S RICE.......�.......................... ...................,
In addition to the cost, we are requesting a time extension of approximately one week for this change. The
extent of the delay will be determined after the additional work is completed.
Please review these two proposals and let us know if either one is acceptable. Feel free to contact me if
you have any questions.
Thank You,
Mark Magney
