Question: • Sheet G-1.1 – Gate may be closed no longer than 60 days for PBB install. This time shall cover all demo, architectural and electrical improvements, structural foundations, and new PBB installation. The Owner will then have 14 days to inspect, verify, test, commission, and coordinate punch list items to be corrected by the contractor. o We take exception with the 60 day limit. Currently, there are extremely long lead times on various electrical components that would easily surpass this limit. Depending on the upgrades required, we may exceed the 60 day limit. o This project requires PBB/Walkway foundations and in anchor tie downs. Depending on environmental conditions, these foundations can take 30 days minimum to cure. • Sheet AP-2.0 – The scope notes on this sheet list “installation of (N) Bollards along A3 walkway” o Is the PBB manufacturer responsible for bollards? • Are side shifting cabs required for this project? Our records shows that the previous bridges installed at VPS included them. • Proposal form item PBB-8 includes foundations for the VDGS. However, sheet note 2 on PBB-8.1 notes that “foundation and pole by others. Please confirm that we are NOT responsible for providing the VDGS foundations and pole. 1.02 – Related Sections • C & D – Aircraft Potable Water Cabinet & Baggage Valets o These items reference sections that are not present in the contract documents. They were also not present on the drawings.

Any replaced items/systems will be subject to the original warranty period. • C – Warranty services shall be commenced with on-site representation, by qualified repair technicians, within 72 hours from the request of the Owner. o TKAS cannot commit to a 72 hour guarantee. Depending on the severity of the repair and the parts required, 72 hours could be exceeded. Lead times need to be taken into account. This is a highly unlikely scenario, but still worth mentioning. 2.02 - Manufacturers • A.2 – Thyssen Airport Systems. o This is the former name of our company. Please allow us to bid as TK Airport Solutions. 2.04 – Passenger Boarding Bridge • B.1 – A high resolution color video camera (CCTV)…to allow the PBB operator to view at a control console mounted monitor. o We utilize our 15” HMI screen to view the CCTV feed, not a dedicated monitor mounted on the console. We respectfully ask that our standard viewing solution be accepted. • B.2.a&b. - This section outlines the requirements for the CCTV camera. It also mentions to provide them “where indicated on the drawings”. o We use Hikvision model DS-2CD1623G0-I(Z) to accomplish this task. Please allow us to bid using our standard CCTV camera. o The drawings do not show CCTV cameras or the required locations. Please confirm the required mounting locations. • B.17 – Interior rain gutters shall be indicated with alternating yellow/black safety striping the entire length. o We can offer either solid yellow or solid black safety striping, not alternating. Please accept our standard offerings. • I.5 – The operational and ultimate swing limits shall include a position sensor located in the rotunda ceiling that shall be accessible from the rotunda interior… o TKAS meets the requirements in this section. However, our swing limit sensor is located in the rotunda floor. The switch is still accessible from the rotunda interior. Is this acceptable? • J.1.f – High pressure laminated wallboard with blacktrim shall be used. o Our standard wall panels are made from a 20 gauge ASTM 635 galvannealed sheet metal. We believe these panels provide greater durability and are easier to maintain compared to Laminate/Melamine wall panels. The outer surface side of the wall panel is painted to the customer’s specified color (our standard color is RAL 9002). • K.1 – Cable Carrier System, Dog Legs (pantograph) o TK uses a side trolley cable carrier mounted on the side of the PBB. This system is utilized globally and is reported by maintenance personnel to be easier to inspect and maintain, reducing maintenance costs over life of the system. The trolley cable system enhances scalability through efficiency in adding cabling for future equipment additions or upgrades. TK respectfully requests acceptance of our standard cable carrier system. • L.7 – Wheel/Tire assemblies shall be solid rubber tire tread on steel wheels as manufactured by Trelleborg or approved equal. o Our standard wheel/tire is manufactured by OTR Wheel Engineering.

OTR is a 30 year old company and has served the PBB industry for many years. We kindly ask that you accept our standard wheel manufacturer as an approved equal. • L.10.b – Vertical Drive (Electro-Mechanical) o This is the primary design standard of our competitor. We are capable of this, but we would prefer to use our standard hydraulic vertical lift system. We have been using this system successfully for the last 20 years. It requires much less maintenance and will last the life of the bridge without major overhaul, unlike ball screw assemblies that have to be torn-down and resurfaced near ten years of service. • M.18 – Operator’s station shall be equipped with an operators platform for the operator to stand on while rotating the cab. o This is another design standard from our competitor. We do not utilize a operator platform in our rotating cab. The operator does not require a special platform to operator our bridges. Please accept our no platform design. • M.20 – Control console doors/lid shall have hold open devices. o Our control consol access door does not have a hold open device. The access door is easily removable to allow for full, unobstructed access to the inside of the cabinet. It features a tool-less removable design. Is this acceptable? • N.2.a (items 3-7) – Indicator lights o Our console design does not utilize “indicator lights” for these functions. We use flashing warning messages on the HMI to accomplish these requirements. Please accept our standard. • N.2.a.8 – A light shall indicate of the adjustable cab floor is in the automatic or manual mode. o Switching between manual/automatic operation modes is done with a clearly labeled switch. The current mode of operation can be determined by looking at the physical switch. Please accept our standard. • N.2.a (items 9-10) – GPU/PCA operating indicators. o These are accomplished with warnings/notifications on the HMI screen. Not “indicator lights”. Please accept our standard. • O.10 – Supplier is required to submit a sample of fabric and associated specifications with proposal. o Samples will be provided with engineering submittals if awarded, not before. • P.7 – A remote audible alarm shall be located at the rotunda or fixed walkway, at the building interface to alert in the event of an auto leveler fault. o Our alarm is located in the Tunnel A, not the rotunda. Is this acceptable? 2.05 – Controls • A.9 – A 6-inch diameter alarm bell located under the aircraft cab shall sound continuously whenever the bridge is in drive mode of operation. o We use a 10” diameter bell to accomplish the above requirement. Is this acceptable? • C.2 – Programmable Logic Controller (PLC): PBB functions and information systems shall be controlled using a Beckhoff Programmable Logic Controller (PLC). o Our design uses Phoenix Contact’s PLCs a standard. Although we have provided PLCs from other manufacturers in the past, the Phoenix Contacts products have proven the most reliable when integrated with our product. Over the years we have integrated specific options and value-added programming into our standard PLC software that will not be available if required to use a PLC from another manufacturer. We request acceptance of our standard PLC. • C.3 – Graphical User Interface (GUI): The control console shall include a Graphical User Interface (GUI) on a 10.4 inch (264mm) touchscreen graphical display… o Our standard HMI screen is 15”. Is this acceptable? 2.06 – Operation and Control Logic • E – Cab floor Adjustment: The cab floor of the PBB shall be both automatically and manually adjustable to align the floor level with the aircraft doorsill. Touch buttons on the GUI shall allow control of the cab floor to be toggled between the automatic and manual modes of operation. o A physical switch is used to change between the different modes of operation, not a GUI touch button. The current mode of operation can be determined by looking at the physical switch. Please accept our standard. • F – Canopy Closure Control: The bellows-type aircraft closure canopy shall be powered for extend and retract operation. The control console shall contain GUI touch buttons to control extension and retraction of the canopy. o We use mechanical push buttons to achieve the above. Our standard mechanical push buttons provide a more tactile feedback over GUI touch buttons. • F.1 The aircraft canopy closure shall be capable of dual activation of both sides of the canopy simultaneously or independent activation of the right or left sides of the canopy in the up or down directions. A GUI touch button shall be provided to select either independent adjustment of the left and right sides of the aircraft closure or simultaneous operation of both sides. o Our design uses a singular mechanical push button to operate both sides of the canopy simultaneously. Our design allows for automatic interdependent left/right adjustment using sensors on the canopy, no dedicated button needed. Please allow us to bid using our standard. • G & H – Floodlights Control & Travel Bell Control o The two items above require GUI touch buttons for activation. We use mechanical push buttons to achieve the above. Our standard mechanical push buttons provide a more tactile feedback over GUI touch buttons. Please allow our standard. 2.07 – Electrical System(s) • B – PBB disconnect enclosure shall have SCCR rating of 35kA or greater. o Enclosures themselves do not have a SCCR rating, this is only applicable to the panel hosting the disconnects. Our panels have a rating of 10kVA. We’ve used these panels over the past 15 years without issue. Is this acceptable? • N – Control console lid, wiring harness should be of sufficient length to allow the panel to be pulled out and turned over, facilitating repairs. o Our console lid is not easily removable, as it is not intended to be used for maintenance access. Our console has an lockable access door/hatch that is easily removable for maintenance purposes. Please allow us to bid using our standard design. • R.2.d – Tunnel lighting shall be provided by recessed LED panel fixtures with diffusers. The fixtures shall be 4 feet long and shall be positioned parallel to the tunnel centerline. o Our tunnel design orients the lighting fixtures perpendicular to the tunnel centerline. Please accept our standard lighting design. 2.10 – Identifications, Markings, Signage & Labeling • C – A metal nameplate shall be riveted to the equipment specifying manufacturer’s name and/or trademark, manufacturer’s part or model number, manufacturer’s serial number, date of manufacture, and equipment’s ratings. o We use a commercial grade sticker complete with the required information in the specification. Is this acceptable? 2.11 – Finishes • D.3b – Color: Brushed Aluminum o This item lists brushed aluminum for the color/finish requirement. But item a directly above this lists coil coated galvannealed steel panels. We offer these panels standard, but in a painted finish only (standard paint color is RAL 9002). Are these panels and paint finish acceptable? • E (items 2 &3) – These two items outline the exterior color requirement (Arctic White) o TKAS offers RAL 9002 as a standard color. It is both aesthetically pleasing as well as utilitarian in its function. With heavy foot traffic, the bridge interiors become soiled with unsightly dirt and grime. Our standard finish helps mitigate this visually. We respectfully request that our standard color be allowed. ? Please note that any color that deviates from our manufacturer standard is considered a specialty finish. Any specialty finish items will need to be decided on at least 6 weeks after Notice to Proceed in order to give us appropriate time to source the product and provide submittals in accordance with the project schedule. These specialty finishes can lead to a significant time delay as well as increased cost. TK Airport solutions will not be penalized for delays due to lead times/indecision on specialty finishes. 3.04 – Inspections • E – After the “Manufacturer” Corrects all discrepancies…or faults are detected. o During commissioning, a punch list will be provided with items necessary for completion. Items/discrepancies that arise, that were not originally on the punch list will be treated as warranty items. We will not agree to a restarting 30 day test period.
