January 26, 2016 RE: Addendum #1 ITB 16-57/CGA Outboard Motors Opening Date and Due Date is February 4, 2016 at 2:00 PM ET Ladies/Gentlemen: Addendum #1 is being issued to provide the following information: To answer questions received. Bidders must take due notice and be governed accordingly. This addendum must be acknowledged as indicated in the Invitation to Bid or your Bid may not be considered. 1) Q: Specifications on the dive tank racks? A: The brand of the requested rack is Roll Control Systems or equivalent. The installation location will need to be on the rear of the aft deck, in two separate track sections. Each section of track should contain two standard tank brackets. So there would be a total of four tank brackets on each vessel. Also the end cap & stop kit will be necessary for each sections of the aluminum track. 2) Q: In regard to the A/C circuit panels, how many circuit breakers will be needed? A: The requested Blue Seas or equivalent A/C circuit panel is;
3) Q: Currently the boats have a USCG maximum horsepower rating of 450. Will the boats be recertified by Safeboat prior to repowering to accept a maximum of 500 horsepower in order to fulfill the bid requirement of installation of twin 250 horsepower engines? A: New data plates have already been obtained from Safeboat certifying each of the vessels to a 500hp capacity. The new data plates will be installed on the vessels prior to the vessels being turned over to the vendor for fulfillment of work. 4) Q: Do we need to estimate new battery cables throughout the boat or will we be reusing the existing cables? Existing cables appear to be in good condition. A: Vendors are to install new battery cables and lugs.
5) Q: Do we need to include replacement of fuel lines and fuel/water separator assemblies to matching Yamaha components or are the existing components going to be reused. A: Vendors are to install new fuel lines and new Yamaha or equivalent (which will not interfere with motor warranty) fuel water separators. Also, the vendor will need to drain and flush the existing fuel tanks and replace the existing fuel sending units. 6) Q: Do we need to estimate new hydraulic steering cylinder(s) or will the existing steering components be reused. Recommend upgrading to Sea Star Tournament series steering system, single cylinder with tie bar and new steering hoses from helm to engines. A: Yes, the estimates should include new stainless steel hydraulic steering cylinders, hoses and necessary components. Hydraulic steering should be Sea Star Tournament Series or equivalent. 7) Q: Is there a location specified for the installation/placement of the dive tank rack(s). Will tank racks be provided or will we need to estimate fabricating the racks. If we need to fabricate racks can you provide specifications for size and quantity of tanks that will need to be stored. A: Question has already been answered above, refer to question #1. 8) Q: Is there a location specified for the installation/placement of the remote search light (estimate will be installing in location of existing search lights unless noted otherwise). Is there a specification for the model of GoLight to be installed? A: The installation location of the new search light will be the same location as the current search light. The model of the GoLight requested is 1568989 or equivalent which also includes a dash mount control along with a wireless remote control. Equivalent light must also meet the following specifications; no less than 400,000cp, 360 degrees of side-to-side motion, and must be rated for marine environment. 9) Q: Battery specifications are provided in the request for bid. Are there any specific details regarding the clause "or equivalent" Does this mean batteries must be same brand, the same type, or just equivalent sizes. A: (4) group 31 Optima or equivalent batteries are to be installed on each of the boats. This will include (2) starting and (2) high reserve deep cycle. Also, each of the batteries are to be installed in battery trays and installed in the same location as the original batteries. 10) Q: There are (3) Blue Seas switch panels for the 12 volt DC circuits located on the port side mounted vertically (picture attached of panels in question). Are all 3 panels being replaced or reused. Are the existing battery selector switches and circuit breakers going to be reused.
A: The (3) DC distribution panels located on the STARBOARD side are to be reused. The battery selector switches and panel are to be replaced. The Blue Seas or equivalent battery switches and systems monitor to replace the existing are as follows; this panel is to be mounted on the overhead console. 11) Q: "All motors, electronics, equipment, controls, gauges, and accessories are to be installed in locations on the boats as specified by Hampton City Police and Fire personnel" Please provide clarifications and specific details for any and all necessary component installations. If no locations are specified we will assume all new equipment will be installed in place of the previous/current equipment on the boat.
A: Fire and Police personnel will consult with the vendor prior to installation to determine the appropriate location for these items. This mainly refers to the navigational electronics and radios. Essentially, Police and Fire personnel will point out where on the dash board these items are to be mounted. The motors, controls and gauges will all be installed in the same location as the parts which they are replacing. 12) Q: Are both boats going to be equipped and fitted identically or will there be ANY differences in equipment installation/location between the two boats. A: Both boats will be equipped exactly the same. 13) Q: Do we need to include replacement of zinc anodes after bottom painting is completed. This is not specified in the bid request and the zincs appeared to be in marginal condition during the inspection of the boats. A: Yes, the bid should include the replacement of all zincs for both boats. 14) Q: With the batteries being 19-20 ft forward from the transom the Optima batteries you are requesting do not come close to meeting the reserve capacity that Yamaha requests on the Offshore 250 s.the battery extension cables that run forward currently are undersize for that application since we experience days and nights where the temperature drops under 32 degrees. The Interstate 31M-AGM battery comes the closest to meeting the required spec and will come with a 3 yr free replacement warranty as apposed to the 2 yr warranty of the Optima. In order to get 3 of them to fit in the portside forward space we will have to use battery trays with lug covers. The battery extension cables need to be upgraded to a 2/0 size, cutting them to the correct length with installing new lugs and heat shrinking the ends, the power posts that connect the engine cables to the extension cables also need to be upgraded. Plus in order for the engines to charge the house battery correctly the addition of 2 charge isolators from Yamaha as these engines have built in regulators that become active when the Isolator lead is plugged in to it providing more of a solid system. A: Portions of this question have been answered in questions #4 and #9. To cover the remainder of this question; As certified outboard vendors, the vendor will need to determine the adequate size of the new battery cables and lugs. Also, the required number of charge isolators are to meet any requirements imposed by outboard manufacture specifications to properly function with the outboard motors. 15) Q: The hydraulic cylinder and hoses that are currently being used also need to be upgraded as they are showing signs of pitting, crimping, age and leaking as well as
being the old style cylinder that is chrome plated steel slider as apposed to a all s/s slide assembly. You may actually want to think about changing the entire system since the helm appears to be original. The correct cylinder is a HC5345-3 then the hoses are ordered based upon the length or a complete kit number is HK-6400TC3 with hoses sold separate also. The tie bar appears to be reusable along with the steering wheel. A: Question has already been answered above, refer to question #6. 16) Q: The Interlux application guide calls for 4-5 coats so as to achieve the 10mil dried thickness. A: Vendor will need to apply (4) coats of Interlux 2000 epoxy barrier followed by (2) coats of Interlux Micron CF (black) 17) Q: The holes in the bottom were filled with epoxy because there did not appear to be any access to the back side of the hull in that area,the problem is that the floatation foam that is used on that hull is extremely flammable and welding from the outside will make it catch on fire to burn under the floor. We believe this is the reason the CG who has unlimited resources available did not have this area repaired. A: If repairing the areas of the hulls in question by welding is deemed unsafe and not an option, then the use of an adequate marine epoxy designed for below the waterline applications may be use to repair the hull prior to the application of bottom paint. All other terms and conditions remain the same. Sincerely, FOR CITY OF HAMPTON Carol Alston Carol Alston WAE Senior Buyer
