SUBJECT: Change Order No -3, Description of Work and Backup Data
A brief description and summary of Change Order No.3 is listed
below and the backup data is attached for your review and
acceptance.
Request for Proposal No. 12, 12A and 12B $ 178,296.00
Control Building Modification.
At the request of the City, the Architectural firm of Morris &
Wenell reviewed for the purpose of value engineering, the
Control Building Modification.
The findings from the Architect's review and recommendations
resulted in B&V issuing to the Contractor, RFP No.12, 12A and
12B.
The major items of work addressed by these RFP's were beyond the
scope of the contract, and are listed below:
1) HVAC sys.:em improvement. The original equipment and
system were outdated, inefficient and/or inoperable,
and the recommendation by the Architect was to install
a new system. Several original work items were
subsequently affected. The roof system was modified to
support the new Air Handling Unit, the acoustical
ceiling was extended to conceal the new ductwork,
resulting in modifications in the lighting system,
etc.
2) Restroom facility. Handicap access was improved
beyond that of the original contract requirement.
The Architectural firm of Morris & Wenell provided the
calculations and drawings for the modifications required. B&V
incorporated these details into RFP No.12 dated 8/31/90, 12A
dated 9/25/90, and 12B dated 10/17/90. In a letter dated
1/10/91, the Contractor submitted a proposed cost of $ 205,676
for the additional work. This proposal was review by the
Architect and a meeting was held 1/30/91, between the Architect,
City, Contractor and Engineer to discuss these items. In a
letter dated 2/20/91, the Contractor submitted a second proposal
for $ 181,324. This was again reviewed by the Architect and was
found to have few exceptions. On 2/28/91, the second proposal
was discussed at a job site meeting between the City, Contractor
and Engineer, and the figure of $ 178,296 was tentatively agreed
upon.
