1 February 14, 2018 ADDENDUM #2 FIBER OPTIC CABLE MAINTENANCE (Revised 1-18) IF18158 BIDS WILL BE OPENED 1:00 PM February 23, 2018 ROOM 16, CITY HALL BUILDING 101 NORTH MAIN STREET WINSTON-SALEM, NORTH CAROLINA Please acknowledge receipt of this Addendum and include with your bid proposal. Jerry Bates Purchasing Director Company Authorized Signature Date Russell Frye Buyer BID CLARIFICATIONS Please see below for questions received from potential bidders and the City s response: 1. Question: Emergency Mobilization - This is normally bid as a percentage to the job, which always reflects real cost. Will the City consider changing the units on this item from each to a percentage? o Answer: Contractors will be compensated for Emergency Mobilization at a rate of 10% of the total job amount. 2. Question: Is all the traffic control is to be included or will a separate unit be provided to bid on? o Answer: (See Page 30) Under the traffic control paragraph the last sentence states: The cost of traffic control is not a separate item and shall be included in the bid price for other items. 3. Question: Are any and all down guys and anchors to be included in the unit price for the messenger? o Answer: (See Section 7 / Page 47) Guy assemblies have their own pay items Line No. 12 and Line No. 13. Anchors and all hardware to be included in guy assemblies.

2 4. Question: Who or what is the deciding factor when a anchor and guy wire is to be installed? If a cable installed by the winning contractor is found to have not been properly anchored and the warranty period has expired, how would this be handled after the 1-year warranty? o Answer: City of Winston Signal System staff will be the deciding factor for installation of guy assemblies. They will also have inspected the work before it could be paid or invoiced. If properly inspected by the City, the work has been paid for, and past the 1- year warranty there would be no liability of the contractor. 5. Question: NC DOT requires a SDR 11 duct to be used but I do not see this in the RFP. What rating is the city requiring? (This is discussed on page 48 but does not match the SDR 11 rating of SCH 80 that NC DOT requires under their roads). o Answer: (See attachment for HDPE from original Phase-A contract) would think we would want to meet the same ratings or requirements of the original signal system installation. The SDR 11 ratings is what was required for conduit in railroad right of ways or areas where it may be exposed to heavy weight. 6. Question: If a drill shot is attempted and rock is encountered how is this handled under these units? o Answer: (See page 45) Section States: No measurement will be made for conduit installation through rock or rock-like soil conditions, regardless of the installation method employed, as such extra work, materials, and equipment will be considered incidental to conduit installation. 7. Question: Are any drill logs or GEO information required by the contractor as was in the City IS project? o Answer: (See Section 5.3.a.4) Section States: Upon completion of the conduit system for communications, furnish the Project Coordinator with a plan of record drawing detailing both the horizontal and vertical (i.e., depth) locations of the conduit system. 8. Question: Is traffic control expected to be included in this unit or will that need to be a separate unit for different situations? o Answer: See the answer from Question-2 / Page-30. Should be considered the same. The cost of traffic control is not a separate item. 9. Question: Is the winning bidder to provide certified traffic control certifications with the bid? o Answer: Certifications is recommended but not required. All traffic control is to conform to the MUTCD guidelines. City is not liable for any incident that may occur from nonconforming traffic control devices. (See page 30 section for General Provisions / Traffic Control)

3 10. Question: Will the winning contractor be required to hold a Corning NPI certification for the duration of the contract to maintain the manufactures warranty? This allows the current warranty form Corning to stay in place for 25 years. Will the cable for the IS be required to be a Corning to extend the warranty? o Answer: We are not sure. This seems too specific to using a specific manufacturer of cable. As the QPL list multiple vendors for fiber optic cable, not just Corning. Corning is not the sole manufacturer that can be used. All fiber optic cable used should meet the cable specifications that are stated in section 9.2. If using Corning, and the contractor is NPI certified, that would only be a bonus to the City. 11. Question: How is the material aspect being handled for the emergency part of the contract? Is the contractor expected to maintain and always have fiber cable and splice cases on hand so materials are not an issue for any emergency? I assume this should be covered in our units? What are the repercussions for the contractor who does not stock and cannot meet these needs? o Answer: The City of Winston-Salem will determine when fiber damage warrants an emergency situations. Contractors will be require to adhere to appropriate response time which would include furnishing materials. Spare material cost should be reflected within emergency mobilization cost for DOT and IS. Concerning repercussions, please see General Requirements sections C (contractor s responsibilities) and section E (failure to perform). 12. Question: Is tree trimming to be covered by the winning contractor under this contract? If so what unit should it be in or will a unit be established? Who is responsible for the debris and proper disposal of it? o Answer: (See section 1.2.d for Tree Trimming) Contractor must contact the City of Winston-Salem Urban Forester for review of tree trimming and to obtain permit (free) for actually performing the work to trim trees. o (See section D under the General Requirements) Contractor is responsible for disposal of all debris upon completion of work. o Tree trimming is incidental to the installation of cable. There will be no separate line item for tree trimming. 13. Question: Page 51 / Plan of Record Drawings - What exactly are the requirements? Please clarify whether we will update the current map or just turn in a new as built in the same format utilizing a Tremble GEO unit. And what unit is this to be priced in? o Answer: PDF Red line (using a PDF editing software) showing as-built conditions must be submitted electronically. See section F under the General Requirements for payment. Contractor must turn in all as-built drawings with invoices. Contact the project coordinator to obtain existing fiber plans for redlining.

4 14. Question: Page 57 / Over-sized Junction boxes provided by the city. Since these are being provided by the city can you please tell me the size so I can price in my unit accordingly? Where will we have to go to obtain these? Also what size is the special sized junction box? o Answer: Contact the project coordinator to get information on obtaining junction boxes. The oversized junction box is 30"(1) X 15"(w) X 24"(d). Special sized junction box is 36"(1) X 24"(w) X 24"(d). See Chart Below: 15. Question: Page 65 / GENERAL - The first sentence in this section talks about testing the data on the reel but I do not see where the work must be tested and the documentation the city requires upon completion of the project. What type of test results are required to be turn in on each job and what format? o Answer: With exception to the drop cable (Page-57), OTDR testing is provided or completed with the splice enclosures. Majority of cable installations for us will be done with a termination point / or splice enclosure to us an OTDR or to test from. For new cables and enclosures, OTDR reports is what is expected. If cable runs have change location or routes then updates to the as-builds would be expected as well. If doing anything with the 6 fiber drop cable or interconnect center for the drop cable, then only the OTDR traces for the fiber used from the neighboring traffic signal network locations would be expected. See section 10.3 (B) for other information or documentation to be provided with new enclosures and OTDR testing. 16. Question: Page 69 / MEASUREMENT AND PAYMENT - This unit is all inclusive and has pulling, termination and testing all in the Communications Cable and is based off the bid sheet on a specific footage. Would the City benefit from separate units based on Cable installation, Terminations and Testing so you only pay once for the exact work completed? o Answer: (NO) Work for installation of communication cable is inclusive to all things stated in that section. 17. Question: In the RFP there are no hourly rates or units just for fiber work or trouble shooting. If a cable is cut or the ring has an issue who will be able to determine the extent of the work needed? Does the city have this capability? o Answer: Space for an hourly rate quotation has been added to the proposal page, separate from the line item prices. Contractors are asked to enter their hourly rate for general services/troubleshooting there. A revised copy of the proposal pages is included with this addendum. Please substitute these revised pages when submitting your proposal.

5 18. Question: Since the NC Statues requires a contractor for any job or bid over 30K to be a General Contractor with a Public Utilities License is this required to be in the bid to be awarded this job or contract? o Answer: The section of the NC Statutes (N.C.G.S Chapter 87, Article 1) to which you are referring applies to construction and repair projects and this project is being bid as a service. No general contractor or public utility license will be required. 19. Question: Line item 21 Is the drop cable (6-fiber) plenum rated? o Answer: (No) Plenum is for indoor use / ventilation areas. All 6 fiber drop cable will be installed outside. 20. Question: Line item 22 Interconnect Center In the description of this item, it states to furnish all components inclusive to the 1RU. However, it could include multiple cables or multiple splices. How do we price not knowing exactly the total number of cables/splices/splice trays involved in each interconnect center? o Answer: All Interconnect Centers are for the 6-fiber drop cables. It will be for a 6 fiber cable, 6-splices, 6-fiber pigtail for tray, 6-fiber face plate etc. These will be installed in traffic cabinets. 21. Question: Line items Hub Splice Center Same question as #20 above. o Answer: See answer to question #20. There is individual line items (23-25) for each size HUB Splice Center and corresponding cable size we have (EX: 24,36,48, 72 count fibers) 22. Question: Line items IS Hub Splice Center Same question as #20 above. o Answer: See answer to question #20. There is individual line items (47-50) for each size IS HUB Splice Center and corresponding cable size we have (EX: 24,48,96, 144 count fibers) 23. Question: Do you have any additional specifications or diagrams? o Answer: (YES) Winning bidder will be provided technical support for system infrastructure, including current as-built plans and or diagrams. 24. Question: Do all of the parts need to come from a single source manufacturer? a. Answer: (NO) But parts must be used from the QPL list. 25. Question: per Leviton, they do not make the RDP enclosures anymore. Is there an alternative? a. Answer: Parts must be used from the QPL list. Check it to see if a similar unit can be found.
