TO: Don Ashworth, City Manager
' FROM: Gary Warren , City Engineer
DATE: October 3 , 1990
SUBJ: Approve Contract Amendment No. 2 for Country Hospitality
Suites Improvement Project No. 89-25
By the nature of the beast , the Country Hospitality Suites
Y ► Y F Y
improvement project has been fraught with coordination challenges
and changes . Working on a site improvement of this nature with
the time constraints imposed by the lending agencies has resulted
in a lot of lost hair on the parts of all parties involved.
The attached Contract Amendment No. 2 provides a synopsis of
necessary scope adjustments which were undertaken as the project
' progressed. The attached October 1 , 1990 correspondence from BRW
accurately summarizes the necessary change elements. Fortunately
in this regard the net change to the contract is a deduct of
$3 ,940 . 06 . This is due largely to the $24,000 savings which
resulted from the decision to use restrained joints on the
watermain rather than ball-joint pipe .
I find the attached Contract Amendment No. 2 in order and
therefore recommend approval and establishing a revised contract
ceiling amount of $320,097 . 89 .

CONTRACT AMENDMENT NUMBER TWO
IDear Mr. Warren:
Please find enclosed six copies of Contract Amendment Number Two for the above
referenced project for your approval . The amendment has been prepared to include
IInew bid items and revis-ed contract quantities as required by the following
modifications to the project:
IIA. Watermain Repair — Dinner Theatre
The plans and specifications specified the installation of Ball Joint
I Watermain pipe to address concerns about the stability of the fill area
where the watermain was to be constructed. Subsequent to receipt of bids,
we reviewed the cost of Ball Joint Pipe, the site, and discussed this
' further with the contractor. It was our conclusion that restrained joint
watermain was a more cost effective solution for this installation and we
directed the contractor to proceed with the installation of restrained
1 joint rather that Ball Joint Pipe.
B. Subgrade Correction — Country Suites Hotel
ISite preparation and subgrade correction were the responsibility of the
developer prior to the construction of the Parking Lot Base by this
I contractor. However, this work was not completed by the developer. They
requested that this work be completed by the City contractor in order to
save time and to allow improved coordination of the work.
IAt the request of the developer and your direction we directed the
contractor to proceed with subgrade excavation and the restoration to
1 subgrade utilizing Geotextile Fabric and extra depth aggregate base as
summarized by Item Number Two of Contract Amendment Number Two.

C. Watermain Repair - Dinner Theatre
An existing hydrant along the Dinner Theatre lot remained connected to the
old watermain (to be abandoned) in order to provide fire protection
service. Once the new watermain was constructed, the old hydrant was
disconnected from the old watermain and reconnected to the new watermain.
This work had not been included in the contract documents previously.
D. Remove Bituminous Pavement - Animal Fair
Removal of existing bituminous pavement and site preparation was the
responsibility of the developer prior to the construction of the parking
lot by this contract. This work was not completed by the developer. They
requested that this work be completed by the City contractor in order to
save time and to allow improved coordination of the work. '
We recommend approval and payment of this contract amendment.
Sincerely,
PA , IrC.

Amendment Number: (2) Two
I Date: October 1, 1990
Contractor: Alber Construction', Inc.
The additions, revisions and corrections 'contained herein shall be made to the
contract documents for the project and shall become a part of the Scope of Work.
IDescription of Changes:
II A. The Contractor has installed field lok gasket ductile iron pipe in substi-
tution for the ductile iron ball joint pipe originally specified for the
water main repair-work east of the Country Hospitality Suites site. The
field lok gasket pipe will satisfy the special design requirements of the;
Iarea at lesser cost than the ball joint pipe.

II feet of ball joint pipe, and the creation of a new pay item for the field
lok gasket ductile iron pipe. The modifications are detailed as follows:
