About this file
This Addendum #3 to IFB 99-JD25021 issued by Guilford Technical Community College (GTCC) in North Carolina clarifies equipment quantities and specifications for an audiovisual systems refresh project across 38 rooms in three GTCC campuses. The addendum addresses vendor questions regarding specific equipment quantities for line items including Extron processors, panels, switchers, amplifiers, speakers, network switches, document cameras, adapters, and various cables. Key clarifications include confirmation that 28 Extron IPCP Pro255Qxi processors and EBP 100 panels are required (with no equipment needed in rooms AT 220 and AT 230), 18 document cameras are needed with 3 designated as spares, 14 Satechi adapters are required with 3 as spares, and 31 network switches are to be provided with 1 as a spare. The addendum specifies that all networking cables must meet Cat6 or higher standards, with Cat6A currently in use, and all twisted pair cabling must be shielded and meet local building codes. The addendum confirms the Barco Clickshare installation location as JWH 220, clarifies floor track ADA compliance requirements for specific rooms, and addresses questions regarding speaker mounting specifications (2x2 flat field speakers per room), existing equipment reuse, and cable cubby specifications. The addendum extends the bid submission deadline by one week from the original May 15, 2026 date to allow vendors sufficient time to incorporate the clarifications into their proposals.
The addendum provides critical technical and logistical clarifications regarding the scope of work rather than introducing new pricing terms or contract conditions. Vendors are required to acknowledge receipt of this addendum by signature and return it with their IFB package. The document confirms that GTCC will provide certain equipment items such as projectors for specific rooms and will handle disconnection of power to existing wall-mounted screens and patching of wall holes, while the vendor is responsible for removing existing screens and installing new ones. The clarifications address discrepancies between the original equipment line items and room-by-room breakdowns, confirming that GTCC will work with the selected vendor to make minor room adjustments as needed and that basic plans have been provided as guides rather than final specifications.

A We have used Monoprice, TrippLite, and Startech. All Have worked well for us.
Q
Section 8.5 states that the Vendor must include an itemized equipment list with cost per item and room digital design schematics (detailed block diagram is acceptable). Due to the discrepancies in line-item quantities and room by room breakdown, will GTCC provide the AV vendor an itemized equipment list breakdown per space? This will be necessary to complete a signal flow diagram.
A GTCC has provided basic plans for you to use as a guide. We may have a couple of rooms that will need minor changes. A GTCC representative will work with Vendor to adjust.
Q In Gerrald Hall, GTCC will be responsible for disconnecting power to existing wall mounted electric screens. Will GTCC facilities also remove the screens or is that responsibility of the vendor? There is potential that there may need patch and paint and that falls under GTCC.
A The vendor will remove existing screens and hang new ones. GTCC will disconnect power and patch any holes in the walls.
Q EBP 100: The rooms will vary on mounting per meeting from wall to desk tabletop. Will GTCC be utilizing existing Extron 2-gang SMB boxes? Do vendors need to account for SMB 112 boxes in misc. costs? If so, how many?
A We can use 11-SMB 112 boxes for Gerrald Hall. No other space needs them. Other spaces currently have an MLC104PlusL. We should be able to use the same cutout. Some places may need a plastic plate to cover excess holes showing.
Q Installation completion date can only be an estimate as there are too many variables for classroom availability and scheduling to state up front based upon standard bid response terms. How does GTCC wish to handle? Is there an GTCC completion date?
A We would like to finish as much as possible before the start of school in the Fall. We realize that this will probably not happen. We will work with the vendor and academic contacts to make rooms available.
