2 BID # DRYDOCKING, REPAIR AND MAINTENANCE OF THE WHATCOM CHIEF FERRY ADDENDUM 1 Questions & Answers ITEM 2 Internal Compartments Q: It is stated for the contractor to assume that lead based paint is present on the surfaces of the internal compartments. It also states that for areas of damaged or degraded coatings shall be prepared to SSPC -SP3 by mechanical means prior to recoating. If lead based paint is present it must be left undisturbed or totally removed by a certified lead abatement company. Is it the intent of the customer to have the lead based paint removed if it is found to exist? A: Work for this year is in the shaft alley and steering compartment voids which do not have lead based paint. The mid-ship, side voids and cross over areas are lead based paint and any necessary work in those areas the lead based paint shall be undisturbed and not removed. Q: Does the estimated 40 man-hours and $200 in materials include all the prep time to ventilate and setup? A: Yes in addition to any needed repairs to the internal coating system. ITEM NO. 3 Clean and Paint Sea Valves Q: Are they simplex sea strainers? ITEM NO.6 Inspect/Repair Propellers Q: A static balancing test of the propellers would have to be done at a propeller repair facility. Since the propellers aren t removed on this item and they are removed in Item 12. This testing should be in Item No. 12 Tailshaft Bearings. Would you consider putting this test in Item 12? A: Yes, the status balance test will be moved to Item 12. ITEM NO.7 Rudders Q: What are Hamilton Jet s latest recommendations for this year s work? A: Hamilton Jet s recommendations are (in addition the existing bid spec language to fine tune and adjust the rudder feedback system for No. 1 and No. 2 Ends including both rudder angle indicators in wheelhouse ) for: Replacement of the directional valve 12V (VIC-DG4S4-018C-G-60) and cartridge. Replacement of the 4 pin socket in one of the RFU s and replacement of one of the two RFU s Sea trials Page 2 of 7

3 ITEM NO. 10 Main Engines and Generator Maintenance Q: In the paragraph where it states as follows: The lump sum price for Main Engine Maintenance and Generator Replacement, should the word replacement be maintenance instead? We are not to replace the generators at this time? A: Yes, maintenance not replacement. ITEM NO. 11 Replace Intermediate Shaft Bearings Q: Does the County have these bearings on hand? A: Yes, the County has two bearings on hand. ITEM NO. 12 Tailshaft Bearings Q: Is the Contractor removing both the No. 1 and No. 2 rudders, propellers, couplings, tail shafts? Since the tail shafts, couplings and propellers are being removed. The contractor doesn t see anything about Tailshaft inspections in the lathe such as cleaning shafts for inspections( run out readings, dye penetrant testing in keyways, thread areas, radius areas between threads and tapered areas, shaft tapers, bearing journal areas and measure bearing journal areas for wear? Since the tail shafts, couplings and propellers are out, should the propellers and couplings have a blue fit check to the tail shafts? Then after the blue fit check is done on the couplings to the tail shafts, the couplings are reinstalled on the tail shafts and the shafts are put in the lathe and the coupling faces are checked for run outs. A: All keyed connections should be blue fit during reassembly. Tail shafts should be cleaned however no other inspections or measurements are required, except where specified in the Bid Specification. Q: Do you want to wait until the shafts, props and couplings are out and deal with these things as a change order if needed? A: No. ITEM NO. 17 Install New Expansion Joint in Exhaust Stack Q: The contractor needs more information on the length and exact location for the expansion joints in the stack area above the silencers? The Contractor needs more information on the travel of 6 inches (total length of expansion joint)? The contractor needs more information for type of hangers needed and how many and where to place them to support the exhaust system in addition to the size of the flanges on the top and bottom of the mufflers/silencers? The additional expansion joints do not appear to be the correct solution since they do not take any of the weight off the final engine exhaust expansion joint and there are no vibration hangers indicated. Need exact location with a drawing for the installation of any of the above. A: Exact details for the required expansion joint diameters are unknown. Upon removal of insulation, Contractor shall inspect existing exhaust piping to determine the correct diameter. Expansion joints shall be Page 3 of 7

4 sized to match existing exhaust piping in the locations indicated in Bid Item 17. If Contractor needs shop drawings in order to facilitate this installation, they shall be developed by the Contractor. For each main engine's exhaust, Contractor is to install pipe hangar prior to pipe elbow up the stack, and at least one pipe hangar adjacent to the new expansion joint. ITEM NO. 18 Install Step on Pilot House Top Q: Last paragraph, does this area need to be touched up with non-skid to restore coatings to previous condition? A: No, there is no, non-skid on the pilothouse roof top nor is any required for the new expanded metal stair treads. Delete and non-skid in second to last paragraph. ITEM NO. 19 Renew Spot Lights on Pilot House Top Q: Are there two spot lights in total, one for each end? Q: Make and model of current spot lights? Are the outside/exterior and interior control mechanisms to be replaced? A: Perko # WHT, 120v, 1000w, quartz/halogen, medium prefocus searchlights. Yes both inside and outside control mechanisms (Perko # WHT lever/control assembly with ½ diameter shaft) are to be replaced. ITEM NO. 20 Repair Life Rafts Q: Whatcom County was going to get us information on a vendor for inspection of the life rafts and information on the renewal of the charge rack? A: Last purchase was from Fisheries Supply/Seattle for (2) life raft hydrostatic releases- Hammer H20 Solas for (2) Jim Buoy Life Raft 1215T- 15 man raft. And another Jim Buoy point of contact is: Cal-June Inc Vineland Avenue North Hollywood, CA (818) Fax (818) @jimbuoy.com Page 4 of 7

5 ITEM NO NO. 2 End Rub Rail Repair Q: How thick is the material that is to be replaced? A: EBDG estimates ½", however existing material should be examined upon removal. New material should be the same thickness as the material removed. Q: Do you have any structural drawings or blue prints on the rub rail areas? A: No, some of the original plans were damaged but there is an old midship section on Page 7 of 7; note this page does have water damage, and is difficult to read. Q: Did you send any drawings package this year? A: No, however please see the attached midship drawing on Page 7 of 7; note this page does have water damage, and is difficult to read. Q: Is the 72 inches of removed weld on each the top and bottom of the rub rail correct? A: Yes, 72 inches are removed from both the top and the bottom Q: Is there access behind the rub rail for welding and painting inside the void space? A: No. A backing strip should be welded like the steel repairs for the keel cooler. ITEM NO. 23 Replace radar system Q: How many array/sensors and the current size? A: There are two sweep-style arrays/sensors and each is 4 feet long. Q: Which radar array/sensor is wanted? A: A 4 (non-dome) sweep style similar to existing to match the TZTL12F. For bidding purposes assume the Furuno DRS12A X-Class (12 kw) radar sensor. Upon arrival and before ordering, the shipyard shall confirm the output power of the existing radar sensors and match the output with the new radar sensors. If the existing is not 12 kw then the appropriate DRS X-Class radar sensor (either 6 kw or 25 kw) shall be utilized with a change order for either a credit or additional cost, shall be done. Q: Do you want a heading sensor? A: Yes a new heading sensor shall be supplied. Q: Do you want GPS? Q: Do you want AIS? Q: Do you want Charts? Page 5 of 7

6 Q: What is the model of the Radar Gearbox being removed? will the new gearbox need the foundation modified? A: That information is unknown. Assume the new gearbox will not need the foundation modified. Any required modification shall be a change order. Q: The new equipment requires DC Power 12 24VDC does the vessel have a suitable PSU available? A: Assume Yes. Q: The vessel has (2) radar pedestals and array; is that changing to just one radar pedestal / array feeding two displays? A: No, keeping with 2 radar pedestals and array. Page 6 of 7
