Question 1

Posted: 4/18/2023

Question: Can you please clarify what agency or agencies the DBE firms need to be certified with?

Response: Please see Addendum 2

Question 3

Posted: 4/21/2023

Question: TK Airport Solutions is listed as one of the approved manufactures, and as an approved manufacture we would like to request that our standard passenger boarding bridge design be accepted. We noticed that there are quite a few design criteria that are specific to one manufacture. Section 11 85 04, 1.01. A.1 - " This specification is intended to include three tunnel type passenger boarding bridges of corrugated construction..." Question #1 - Our standard bridge tunnel design consists of the exterior side, roof and floor panels manufactured from 14 gauge galvannealed (galvannealed material provides additional corrosion protection superior to hot-rolled, coil steel, and galvanized) steel panels attached to a framework of angle and tubing. These panels are formed, welded, sealed and painted to form the steel enclosure. Strength is derived from the formed sheet metal ribs, while the flat, exterior walls provide a pleasing architectural appearance. As an approved manufacturer, we feel that our standard design should be allowed.

Response: Please see Addendum 2

Question 5

Posted: 4/21/2023

Question: 118504-2.04. B.7 - "Additional handrails, ladders, cages etcetera shall be provided as necessary to gain OSHA compliant and protected access to any roof located equipment requiring access." Q#3 - Maintenance of the vertical lift motor is performed at apron level on our bridges so we do not require roof access or routine maintenance on the roof. Therefore, a service ladder and roof top handrails are not required on our bridges. We will provide the other compliant fall protection listed in the specification and it will provide the required safety needed should someone wish to access the roof. We kindly ask for an exception to this requirement as it is not necessary and will result in a cost savings to the customer.

Response: Please see Addendum 2

Question 7

Posted: 4/21/2023

Question: 118504-2.04. B.17 - "Transition ramps shall be identified by using a durable, one-inch, yellow (OSHA Alert Yellow) trim band at the beginning of such ramp or hazard." Q#4 - Our standard interior rain gutter is manufactured from extruded rubber and due to the manufacturing process, it is only available in in solid black or yellow. We kindly ask that you accept our standard rain gutters in black or yellow and please confirm which color you prefer.
