ADDENDUM NO. ONE (1) 1. QUESTION: Page S-1 of 18: 2. ENGINE: Please allow for current EPA compliant engines. An On-Highway engine will have to be a Tier IV engine. Current EPA regulations and the FAA allow for Tier III engines under a transition program until 2017. A Tier III off-highway engine does not require all of the antipollution additions, maintenance and expense. Most other airports do not wish to use Tier IV engines until they have to. Please allow for Tier III offhighway engines as well as Tier IV on-highway engines. That way all manufacturers will be able to bid the engine that best fits their application. All engines must be Tier IV on highway. 2. QUESTION: Page S-1 of 18: 3. Transmission & Transfer Case: Please eliminate the (smart-shift) requirement. It is proprietary to only one manufacturer and is only used in on-highway, high-speed applications. In an airport runway application the smart-shift is not used. The requirement is restrictive and that particular feature is not available to other manufacturers. The term smart-shift is intended to describe the general function only. Manufacturers shall use similar technology which provides for automatic shifting. 3. QUESTION: Page S-14 of 18: 6. AUGER: Please allow the auger to be driven mechanically as well as hydraulically as long as the auger is reversible. Mechanically driven is acceptable. 4. QUESTION: Are bids for each type of equipment separate? Bids are to be on one form only and the bidder must bid all items including surplus credit. 5. QUESTION: Is the 5000 ton per hour requirement for the rotary plow 3rd party certified or theoretical tonnage? The 5000 ton per hour requirement for the rotary plow will be 3 rd party certified actual tonnage. 6. QUESTION: What is meant by "schedules"? Schedule is Base Bid and Surplus Equipment Credit in the bid form. 7. QUESTION: Can I bid the snow blower only without bidding the brooms and trade-ins" No. 2
8. QUESTION: The pricing sheet allows pricing for the five (5) brooms and separate pricing for the one (1) snow blower and separate pricing for the five (5) used units. Correct, award is based on total of all units plus credit for surplus. 9. QUESTION: Can I just bid the snow blower without any submission of prices for the other two schedules? No. 10. QUESTION: Is the purchase of the intended snow removal equipment federally funded, or sourced with other funding? ANSWER Federal and State funds will be used. 11. QUESTION: Part 1 4x4 Carrier Vehicle describes the chassis configuration and required options. Is this section to be used for both the broom and blower chassis?

QUESTION: Page BD 3 of 16, Contract Time Specification: 240 Calendar Days Requested: 300 Calendar Days Contract time shall be 300 Calendar Days 32. QUESTION: Page S-1 of 18, Transmission and Transfer Case Specification: The transmission shall be five-speed electronic control automatic. Requested: The transmission shall be five-speed minimum, electronic control automatic. The request is acceptable. 33. QUESTION: Page S-1 of 18, Transmission and Transfer Case Transfer case shall be two speed type with an automatic locking/unlocking differential to control the torque between front and rear axles. Requested: The transfer case shall be of optional single or two-speed type with automatic locking/unlocking differential to control the torque between the front and rear axles. Reason: The transfer case provided will be a single speed. Single speed transfer case utilizes a limited slip differential which constantly and automatically proportions power to all drive axles. Normally there is a constant 50/50 split between the front and rear axles. As traction conditions warrant this split can be applied ranging from 75/25 (front-rear axles) or 25/75 (front-rear axles). No operator input is required. By utilizing all six available gears (Allison RDS) the one speed transfer allows for maximum low-speed/low gear power performance without the need to Delta No. 14051 10 May 18, 2016

QUESTION: PART 2 22-FOOT POWER BROOM WITH AIR BLOWER Page S-11 of 18, 12, Hydraulic System Specification: Shut off valves for all filters below tank fluid level shall be installed to allow filter changes without loss of oil. Requested: M-B is requesting to have the shut off valve element removed because a manual shut-off valve is not required for routine hydraulic system filter changes servicing of the hydraulic system. Reason: M-B has maintained that shut-off valves in the hydraulic circuit can cause catastrophic pump and or motor failure if they are left in the closed position when the system is energized. Therefore, we have not supplied our systems with shut-off valves for this reason. The filters positioned below the hydraulic tank are downstream of the pumps, which act to stop the flow of hydraulic fluid during the filter changes. The leakage Delta No. 14051 12 May 18, 2016
is minimal. The request is acceptable. 42. QUESTION: Please provide the minimum requirements for the Rotary Plow and Broom auxiliary engines. See answer to questions 20 and 21. Delta No. 14051 13 May 18, 2016
