1 1. Are City/County building permits required for the microwave equipment installation? No, permits are not required for the microwave equipment installation. 2. Twin peaks structural- The RFQ states that the bidder must include a structural analysis and upgrade if needed? Is there a current structural analysis available for the tower? In theory, if the tower currently passes, the removal of 7 antennas and the addition of 2 would result in less wind load. Quoting a structural analysis regardless, for up dated records is no problem, but quoting an upgrade without knowing whether or how much the tower is overstressed is not reasonable. Vendor is required to perform structural analysis if needed. 3. Twin peaks tower access- Someone noted the tower is not climbable, what is the specific concern or reasoning and what would the preferred method for access be? Vendor must determine, through structural analysis, their preferred method of access. The City has no preference, HOWEVER, vendor must ensure that tower climbers can furnish certification and have appropriate safety equipment to include, but not limited to, harness, hard hat, etc.. 4. Is a structural review of the existing mount required at One Market? Are as-builts available? No, structural review of the existing mount is not required at One Market. No, As-Builds are not available. Page 1 of 8

2 5. Alarms- we did not see any alarm tie in/termination points, what is the scope for routing and landing and testing the radio alarms and TSM? Please see sections and Scope of Work in the RFP.. 6. Twin peaks- 7 dishes are marked for removal, are any of these active? if active, who will be re-routing traffic? Will all cabling, mounts and ancillary hardware also need to be removed? Are antennas slated for removal to be disposed of installation vendor or will they be required to be transported to a customer staging area? Will the existing waveguide need to be mined? To entry port? To radio? Any other materials that need to be disposed of or salvaged? No, none of the 7 dishes marked for removal are active. Yes, cabling, mounts and ancillary hardware will need to be removed. The installation vendor should dispose of antennas slated for removal. The existing waveguide need to be mined to radio. No, there are no other materials that need to be salvaged or removed. Page 2 of 8

3 7. Is there an existing path between Market Plaza and Twin Peaks? If yes, are we responsible to remove and dispose of all existing microwave equipment? Between One Market Plaza and Twin Peaks, there is an existing microwave system for CERS/PERS system (700/800 MHz Emergency voice and data communication). The new Public Safety Building Microwave project is a new standalone system which will be on a separate path and separate frequency. The proposer needs to perform a new frequency search and selection for this project as part of the RFP process. The proposer needs to select the frequency in such way that the frequency should not interfere with existing microwave (CERS/PERS) path and frequency. 8. RFP called for equipment replacement. Market Plaza and Twin Peaks have existing communication room with DC equipment. are there a requirement to replace these DC equipment? If not then does the proposed DC equipment for 3 rd Street site has to match with the other 2 sites? This is not a replacement project, the existing DC equipment at One Market Plaza and Twin Peaks are part of the existing system. At One Market Plaza and Twin Peaks the proposer can power up the equipment from existing infrastructure (48 VDC ). If there are any additional power requirements at any site, the proposer need to propose those details in the RFP. Page 3 of 8

4 9. What is outage window for cut over? There is no interface to the existing microwave system or traffic. There is no outage widow for cutover expected. 10. The RFQ notes that this is a replacement for the existing system. There was no detail or discussion referencing a cutover of any traffic, is a cutover required, at which sites? This RFP is a new standalone system. There is no replacement of existing Microwave system involved. 11. need drawings for rd Street for dish placement, radio placement and cable routing. The drawings for the new PSB at rd Street will be furnished to vendors who have completed the City s Electronic Data Transfer Agreement. Dish placement, radio placement and cable routing should be determined and proposed in vendor s response. Page 4 of 8

5 rd St- will grounding, AC power, DC power, battery backup, cable tray/conduit, rack, etc. be provided or does these need to be covered in the bid? The City will supply the following: AC, cable tray, conduit and rack. The vendor must supply the following: DC power, battery backup and all other ancillary equipment for installation. 13. To verify/confirm- at 1 market and twin Peaks we are to use existing racks, existing DC power and existing battery plants? Yes, use existing racks, existing DC power and existing battery plants at One Market Plaza and Twin Peaks. 14. ODU's- there are various statements in the RFQ pertaining to ODU's, what is the preferred or required configuration? Direct mount to dish, mounted behind dish with WR42 waveguide/flex between dish and ODU or mounted in an easily accessible location that does not require fall protection or other safety measures to access, using waveguide with WR42 flanged connectors from the antenna to the ODU location? The City prefers easily accessible ODUs. All other decisions should be proposed in the RFP. Page 5 of 8

6 15. if waveguide is to be used with the last option above, pressurization must be considered. New for 1245, but are there existing we can use at the other 2 sites? Jim this one is for you. If pressurization is to be used, all equipment needs to be new. 16. What is the actual demarc- a DSX, router, RJ patch panel, 7705, existing customer equipment? the RFQ notes the radios must be capable of TDM and Ethernet, but I don't see a specific requirement for how the radios are to be wired out, connected to CPE, etc.? Vendor should propose the demark requirements in their response. 17. Are there any on site work hour limitations? DT will discuss the project schedule/site work hour limitation with the winning vendor. 18. What is required throughput? Please see section in the RFP for the required throughput. 19. Are we required to bid new GPS Clock? Bidding a new GPS Clock is at the discretion of the vendor. Page 6 of 8

7 20. On page 7 of 27, of the P500, Professional Services Contract, in Section 19, Liquidated Damages, what is the sum for liquidated damages per day for each day of delay beyond scheduled milestones and timelines? This project s value is not significant enough for the City to institute Liquidated Damages in this agreement. This section will be deleted and identified as Left Blank by Agreement of the Parties. However, the City will identify a payment schedule with the awarded vendor. 21. On page 8 of 52, Section of the RFP #2014-5, states that all antenna mounting structures will require a structural analysis prior to mounting antennas. However; under Codes and Standards it does not list which Standard/Code will be required. Will all sites be using TIA- 222G or IBC (if IBC which year is the current adopted for the City building code), or will it be split between the two Codes, the tower requiring TIA-222 and the building mounting antennas fall under IBC. This comment should be addressed in the vendor s response to the RFP. Page 7 of 8

8 22. In Section of the RFP, CCSF requires a microwave system management, configuration and monitoring tool that enables end-toend network and service management across all domains of the converged, all-ip network. The Configuration and management software should be Easy-to-use GUI that accelerates configuration and provisioning of Microwave network, VPLS, VPRN s and VPNS and DS1/T1 using a single tool. This tool and any associated hardware or licensing should be provided as well. Is the requirement of having single tool or monitoring and configuration Mandatory? No, it is recommended but not required. It is preferred based on the RFP, but alternatives will be considered. 23. In Section of the RFP, are requirements 19, 20, 21 mandatory? Yes, 19, 20 and 21 are mandatory. All similar technology will be considered. End of Document Page 8 of 8
