documents and construction of an Office Facility on Delta
Fair Boulevard near Belle Drive, Antioch, between the

The construction fund established under the Trust Agreement
with the Contra Costa County Public Facilities Corporation,
dated June 1, 1986, providing for the delivery of the 1986

any other anticipated Change Orders.
III .REASONS FOR RECOMMENDATIONS/BACKGROUND.
A. The original contract for preparation of final design
and construction.- documents and for construction of the
office facility was based on a performance description
of the various building systems. The contract
specified comfort conditions such as temperature and ,
air velocity for the heating, ventilating and air
conditioning system.
B. While the Contractor' s design, a water source heat pump
system, appeared to meet the minimum Contract
performance requirements, the General Services
Department, Building and Grounds Services, found that
the design would result in; excessive maintenance costs.

C. It was determined that a built-up chilled water, hot

maintain and, even with the change order cost,
would be more cost effective over the life of the
system.
