' MEMORANDUM
TO: Don Ashworth, City Manager
FROM: Gary Warren, City Engineer
DATE: July 18 , 1990
' SUBJ: Approve Contract Amendment No. 1 for Lake Drive East
Improvement Project No. 89-6
Soils encountered on the east 300 feet of the City' s Lake Drive
East project near Dell Road have been determined by our soils
1 consultant to be unsuitable for roadway construction. This is
somewhat compounded by the extremely wet conditions experienced
this spring and summer. In order to proceed with timely
' completion of the project and to assure the future integrity of
the roadway construction , it is necessary to subcut the easterly
300 feet of this project three feet and to install approximately •
600 square yards of geotextile fabric for soil stabilization.
1 The net increase in the cost for this contract amendment is
$27,177 .50 . An additional five working days has been allowed for
this effort.
1 The added cost for these improvements will be assessed
proportionately back to the properties in accordance with the
' original assessment policies as laid out in the feasibility
study.
It is therefore recommended that the attached Contract Amendment
1 No. 1 for the Lake Drive East Improvement Project No. 89-6 be
approved in the amount of $27 ,177.50 and a revised contract
ceiling established at $741 ,871.84. Similarly, an additional
' five working days shall be added to the contract time for a total
of 55 working days for the project.
