TOPIC: Ross Annex Third and Fourth Floors HVAC Automation
AGENDA TITLE
Award a Purchase Order to Siemens Industry, Inc. in the Amount of $400,000 to
Automate Heating, Ventilation, and Air Conditioning (HVAC) Building Controls at the
Ross Annex (Specification No. 23-047) (General Fund)
RECOMMENDED ACTION
Authorize a one-time purchase order and payment to Siemens Industry, Inc. for the
automation of HVAC building controls on the third and fourth floors of the Ross Annex
Building in the amount of $356,538, plus a contingency of $43,462, for a total amount
not to exceed $400,000, subject to non-substantive changes approved by the City
Manager and City Attorney.
DISCUSSION
The Public Works Agency’s Parks, Fleet, and Facilities Services Division oversees City
facilities to ensure mechanical systems operate reliably and efficiently, as well as meet
all applicable laws and regulations. In an effort to improve building efficiency and reduce
energy and maintenance costs, the Facilities Services team recommends automating
the heating, ventilation, and air conditioning (HVAC) system at the Ross Annex. The
existing pneumatic control system is outdated and not efficient.
HVAC automation of the Ross Annex’s third and fourth floors would allow Facilities
Services to control temperatures for optimal energy usage and comfort from an existing
building automation system (BAS) workstation that currently controls City Hall, the Main
Library, and Newhope Library. The BAS system assists in identifying where problems
originate, which enables staff to quickly respond and rectify the issue. The system also
provides continuous monitoring and adjusts performance to meet changing building
conditions. The improvement is a continuous effort to standardize and integrate City
facilities onto the same BAS.
Santa Ana Ordinance No. NS-2312 authorizes the City to purchase against contracts
issued to vendors who have been awarded by a State Agency, County, City, or other
Public Agency after a competitive bidding process substantially equivalent to the City’s
standard bidding process. Sourcewell (formerly National Joint Powers Alliance)
awarded a contract to Siemens Industry, Inc. (No. 030421-SIE) for the procurement of
