MEMORANDUM
DATE December 1, 1989
TO Rick Svehla, Deputy City Manager
FROM Jerry Clark, City Engineer
SUBJECT Change Order #1 - Bonnie Brae
As with all CIP projects, a rock clause was inserted in the
likelihood that storm sewer construction would encounter rock
excavation That estimated contract quantity was 50 cubic
yards at $70 per cubic yard The construction in the Emery
Street outfall was almost completely in a rock body An
additional 1,313 cubic yards above the 50 cubic yards were
excavated. There was no opportunity to get above the rock as
the outfall pipe was already installed
This change order would increase the contract by approximately
$92,000 we feel that the rock excavation encountered on this
project was not normal as all the recent CIP projects have not
needed major change orders of this type The only way to know
the extent of rock excavation is to employ very expensive
coring tests Those tests would run in the range of $5,000 -
$10,000 per project.
The funding for this change order is available from interest
earned on the 1985 Street Bond Issue (434 Fund)
Please submit this change order for approval to City Council on
December 5, 1989.
