General contractor has submitted the following question from Interclean with a Section 11 11 26, page 434 item 13: There is a requirement for fresh water back-up systems. We will provide a backup fresh water system (provided there is room for the storage tanks) for the recycled water used for the wheel and under chassis sprays, but the backup for Culligan RO Water System needs to be developed by Culligan to assure proper performance and integration into the controls they provide. We cannot provide an automatic fresh water back up supply for the Culligan RO system. A. Confirmed that no work under this contract is to provide back up fresh water supply to RO generation system. Existing RO system has in place an existing fresh water supply connection controlled by float valve to remain.

Q4. General contractor has submitted the following question from Interclean with a Section 11 11 26, page 435 item 16: Blowers / Panels / Controls / Gratings are provided by others (Aerodry). We will supply the phot eye to turn the blowers on and off to keep them integrated into the main wash program. A. No exceptions taken to proposed washer / blower integration description provided. Q5. General contractor has submitted the following question from Interclean with a Section 11 11 26, page 435 item 16: Undercarriage Blowers / Panels / Controls / Gratings are provided by others (Aerodry). We will supply the phot eye to turn the blowers on and off to keep them integrated into the main wash program. A. No exceptions taken to proposed washer / blower integration description provided. Q6. General contractor has submitted the following question from Interclean with a Section 11 11 26, page 443 item F Controls: Just for clarification purposes, the system we are proposing will include a control panel for each lane in the equipment room and 1-HMI that can be used to control the key functions (on/off, activate, deactivate) of all three wash lanes. The user can toggle from one lane to another to prevent access to more than one lane at a time. Also, although we can normally provide a Window/Linux system, these unique features require a PLC based program. A. Design team interrupted the single (1) HMI referenced above as a description of the specified Secondary Remote Control unit. No exceptions taken to a single unit that can be toggled between the lanes. However note that the drawings have been revised by this Addendum #4 to clarify the location of the Secondary Remote Control Unit. Although shown and noted in a specific location on the revised drawings, the final location of the Secondary Remote Control Unit will be finalized during the washers shop drawing review but the intent is for the Secondary Remote Control(s) to be located outside of the existing Water Reclaim Room and on the CMU wall along gridline G facing into the wash bays with direct view of wash equipment. Activating the Secondary Remote Control(s) and then having to move to and look out a door or around a corner is not acceptable. Q7. General contractor has submitted the following question from Interclean with a Section 11 11 26, page 447 item 17 [HMI Interface]: We will provide a feature that allows for the activation of the solenoids and booster pumps within the wash system to verify their functionality, however there is no provisions for manual purging of all water pipes using compressed air. If this is required, it should be in the plumber s scope of work. A. Delete requirements of Section 11 11 26, item 2.01, F Controls, number 17.

Q9. General contractor has submitted the following question from Interclean with a Section 11 11 26 page 448 item 6: We will supply stainless steel covers for the motors in the wash bay and will also be TEFC rated. The motors in the equipment room cannot be covered. A. No exceptions to stainless steel motor covers in wash bay as described.

Based on being primarily sized for transit buses, the major wash components (brushes, spray arches, curtains, rinses and blowers) may not fully clean NRVs. If the washers being bid are not suitable for NRVs or any vehicle listed on AD.4.1 it should be included in writing with the submitted bid.
