Request for Proposals for Installation of Broadcast System for Community Services Building (CSB) 104 I. INTRODUCTION AND INSTRUCTIONS A. Purpose of the RFP This Request for Proposal (RFP) is issued by the City of Burbank, California (hereinafter referred to as the City). The purpose of this RFP is to retain a qualified company that will furnish and install a video camera system that is capable of broadcasting live events from the City s Community Services Building. B. RFP schedule of events This schedule of events represents the City s best estimate of the schedule that will be followed for this RFP. If a component of this schedule, such as the deadline for receipt of proposals, is delayed, the rest of the schedule will be shifted by the same number of days. The approximate RFP schedule is as follows: RFP issued: May 4, 2016 Mandatory pre-proposal tour/meeting: CSB 104 150 N. Third Street at 10:00 A.M., Thursday, May 12, 2016 Written questions due: May 20, 2016 Proposals due: May 26, 2016 Review of proposals: May 27 - June 10, 2016 Contract award: June 23, 2016 Execute contract: July 11, 2016 C. Background The City of Burbank operates a government information TV station, The Burbank Channel (TBC), which broadcasts on Charter Communications Cable Channel 6, AT&T U-verse Channel 99, and streams live on the City s website, Burbankca.gov. 3
The Public Information Office (PIO) currently utilizes broadcast equipment in the City Hall Council Chamber to televise live government meetings from Burbank City Hall at 275 E. Olive Avenue. This is currently the only City location with permanent equipment that allows City meetings to be broadcast live on TBC. In 2009, construction was completed on the Community Services Building (CSB) at 150 N. Third Street. The three story facility features a large meeting room (CSB 104) on the first floor that is often used for community meetings, staff presentations, and Council budget sessions. The original design plans included the installation of video cameras in CSB 104 to allow for live television broadcasts of public meetings, community workshops, and special events. However, the broadcast equipment was never installed due to the reduction of funding during the construction phase. Crews did install cable conduit and built a small room within CSB 104 that could serve as a production control room (Media Room 103), in the event that broadcast equipment was ever installed. In April 2010, Burbank City Council authorized the implementation of a 1% Public, Education, and Government (PEG) access fee to be paid by video service franchisees, Charter Communications and AT&T U-verse. In June, 2013, as part of the FY 2013-2014 budget, City Council approved the use of PEG funds to equip CSB 104 with broadcast equipment to televise public meetings. II. SCOPE OF WORK A.
