FOR MEETING OF:
ITEM TITLE: RESOLUTION #7976 : Authorizing Change Order #30 to th
Construction Contract for the Chula Vista Library
SUBMITTED BYE Director of Public Works, City Engineer ~~)
U-
ITEM EXPLANATION
The Director of Building/Housing and the Library Project
Coordinator support the architect`s recommendation that
Change Order #30 to the Chula Vista Library Construction
Contract be approved.
This change order involves the installation of condensate
drains for six air-conditioning units located on the roof o
the library. The drains are an absolute necessity which we e
not included in the library plans due to an oversight by th
architect's mechanical engineer.
Since the mechanical engineer is at fault for not including the
drains, he has agreed to pay the difference in the cost of n-
stallation now and what it would have been prior to the lib ary
construction. This amounts to about 20% of the $2,644 cost
for labor and materials, or $533. An invoice has been sent to
the mechanical engineer in this amount.
The following change orders have been approved thus far:
