Re: Liberty Street / Two Mile Drive Water Improvements Project
Engineering Change Order
Recommendation
This memorandum is to recommend Council authorization for a change order to the
Liberty Street / Two Mile Drive Water Improvements engineering contract. The
proposed change will increase the limit on engineering fees by $9169, from $20,051 to
$29,220. An expanded scope of work was approved by the Interim City Manager, as
indicated in the attached memorandum of July 17, 1996. Although we under estimated
additional engineering costs at that time, we believe the requested fee increase is
appropriate.
Background
The engineering contract identifies the, need for the project and our initial concept for
water main installations. The scope of work directs Carver Engineering to perform a
detailed analysis of the water system in that area to determine the most appropriate
design concept to meet the identified need.
The above referenced memorandum includes our recommendation and Al Thelen's
approval for an expanded design concept. The attached letter from Carver Engineering
describes the concurrent need for engineering services beyond those included in our
original agreement.
Project Status
Construction for this project began in October 1996 and was shut down due to winter
weather on November 15th. Construction will recommence as spring weather allows.
We can expect approximately two weeks of work along Liberty Street from Hawthorn
to Meridian and another two weeks of work along Two Mile Drive from the Gateway
West Apartments to Glenwood Drive.
The new connection across Three Mile Drive at Northern Lights Boulevard has been
activated. Customers along Northern Lights Boulevard between Liberty Street and
Three Mile Drive are enjoying an increase in water pressure, from approximately 35 psi
before the work to 60 psi today.

Re: Liberty Street Water Project Ward I

This memorandum is a request for authorization to direct Carver Engineering ward I
to expand the Liberty Street Water project beyond the original scope of design. Norbert F. Dora^ue
This project is funded by the recent sale of revenue bonds. A decision to expand ward 11
the scope of work will require a commitment to spend up to $77,000 from the Dale Haarr
Water replacement fund for additional construction costs. Ward 11
Jim Atkinson
Staff will wait for authorization before directing Carver Engineering to proceed. ward III

Background Ward III
Carver Engineering's Preliminary Design Report for the Liberty Street Water project Pamela B. Kenneav
has identified the need for three additional blocks of 8 inch water main to provide Ward Iv
adequate fire flows south of the project area. Our original construction estimate M. Duane Lar:on
was $90,000. Carver's revised estimate of $199,000 includes $101,000 for the ward Iv
additional water main.
After reviewing the Preliminary Design Report, staff believes that the project scope
must be modified. The alternatives are as follows.
l . The scope of work could be expanded as recommended by Carver Engineering.
This would accomplish the original project goals by establishing a south loop on
the Upper Service Zone (USZ) and improving water service for customers west of
Meridian Road between Liberty Street and Three Mile Drive. As stated above,
the construction cost of this alternative is $199,000. Engineering costs would
also increase by approximately $1500.
2. It may be feasible to reduce the scope of work and provide water service
improvements for just the area west and north of Northern Lights Boulevard and
Liberty Street. Further water system modeling is required to confirm adequate
system performance in this configuration. If chosen, this alternative would
eliminate the much needed south loop for the USZ and leave residents on
Glenwood and Rosewood north of Liberty Street to continue with low water
pressure. The cost of this alternative is estimated roughly at $60,000.

Recommendation
Staff recommends the City accept the engineer's recommendation to expand the scope of
work. The south loop for the USZ will provide another point for the USZ to cross Highway 93
and insure more reliable service for large portions of our water system. Also, customers on
Glenwood and Rosewood north of Liberty Street have a need, equal to those customers on
Northern Lights, for improved water pressure.
Project Budget Information
We have combined budget information below regarding the Liberty Street and Two Mile Drive
water projects because both jobs are being designed by Carver Engineering under a single contact.
Our original estimates for engineering / contingencies and construction for the Liberty Street
Water project were $18,000 and $90,000, respectively. After negotiating our engineering
contract with Carver Engineering, we have approximately $8000 remaining for contingencies.
This provides $98,000 and leaves $101,000 to be funded from other sources.
Our original estimates for engineering / contingencies and construction for the Two Mile Drive
i Water project were $18,600 and $93,000, respectively. After the engineering contract, we have
approximately $8500 remaining for contingencies. Carver's updated construction cost estimate
for this project is $76,000, leaving a surplus of $17,000 in this category. This leaves an
estimated surplus of $25,500 which may be redirected to the Liberty Street project.
A tabulation of budgeted funds and anticipated costs is shown below.
Budgeted Revenue Bond Funds
Engineering and Contingencies for the Liberty Street
and Two Mile Drive Water projects $ 36,600
Original construction estimate for Liberty Street Water $ 90,000
Original construction estimate for Two Mile Drive Water 93 000
Total Budget Revenue Bond Funds $ 219,600
Project Costs
Engineering services for the Liberty Street (expanded)
and Two Mile Drive Water projects $ 21,551
Carver's construction estimate for Liberty Street Water
with the expanded scope of work $ 199,000
Carver's construction estimate for Two Mile Drive Water 76,000
Total Estimated Project Costs $ 296,551
The above information indicates that $76,951 is required from sources other than water
bonds. We recommend that $77,000 be committed from the Water Replacement Fund so
we may expand the scope of the project.

Subject: Liberty Street Water Project
Dear John:
Civil
Structural
Environmental
This information is provided in response to your letter dated December 12, 1996
concerning the increased scope of work and associated design and construction
management fees for this project.
As you noted in your letter, three extra blocks of water main were added to the
project after the fees for design and construction management had been negotiated.
These three extra blocks of main represent a 61 % increase in the footage of main to
be installed. Because of this increased project scope, both the design and
construction management efforts are greater than initially estimated.
The design has long since been completed. Our records show that the increase in
design costs was only 38 % of the original established design fee. A tabulation of the
extra time spent by all personnel has been provided earlier. We propose that the
engineering design fee be increased by the actual costs for the extra design work
rather than a percentage equal to the increased footage. We propose that the
construction management fee be increased by the same percentage as the increase in
piping footage since, in generai, construction efforts are directiy related to the
amount of pipe being installed. In other words, we propose that the design fee be
increased by $4,957.45 to $18,132.45 and the construction management fee be
increased by $4,209 to 11,085.
Call me if you have any questions.
