Dis­ad­van­taged Busi­ness Enter­prise – 49 CFR Part 26: 

Can you please con­firm the cer­ti­fi­ca­tion agency, and the estab­lished goal for this project, if any?

Answer: No goal has been estab­lished for this par­tic­u­lar project as par­tic­i­pa­tion is inher­ent­ly lim­it­ed due to the speci­fici­ty of items pro­vid­ed. Please refer to GC-42 Dis­ad­van­taged Busi­ness Enter­pris­es Program.

Sec­tion 3

Exe­cu­tion, page 80 of 87. Sub­sec­tion 3.1 Exam­i­na­tion. A.1 ​“Foun­da­tions includ­ing anchor bolt pat­terns,”. Please con­firm if the exist­ing foun­da­tion will remain and if so, whose respon­si­bil­i­ty is it to ver­i­fy the struc­tur­al sta­bil­i­ty of the foun­da­tions? TKAS, if award­ed, can and will pro­vide foun­da­tion loads.

Answer: As with pre­vi­ous PBB replace­ment projects at the Air­port, it is intend­ed that exist­ing foun­da­tions and bolt pat­terns will remain. As per Sec­tion 3 – Exe­cu­tion, Sub­sec­tion 3.1 Exam­i­na­tion, A., it is the respon­si­bil­i­ty of the suc­cess­ful bid­der to ​“Ver­i­fy that the fol­low­ing are of prop­er size and type to receive the Pas­sen­ger Board­ing Bridge (PBB):”, to include foun­da­tion and bolt pat­tern. Pre­vi­ous­ly bolt pat­terns and foun­da­tions were field ver­i­fied for suit­abil­i­ty and bolt pat­tern con­fir­ma­tion pri­or to manufacture.

Sec­tion 2.2. page 7, B. 6.

“Rotun­da floor shall remain sta­tion­ary and lev­el at all times and pro­vide a smooth tran­si­tion between the ter­mi­nal and tele­scop­ing tunnels.”

Our rotun­da floor moves when PBB swings. This only hap­pens dur­ing dock­ing to the air­craft when no pas­sen­ger is allowed in the PBB. After PBB is docked rotun­da floor is lev­el at all times and pro­vide smooth tran­si­tion between ter­mi­nal and tele­scop­ing tun­nels. We imple­ment­ing this design change as a stan­dard because it helps saves time on instal­la­tion and main­te­nance. All sen­sors are locat­ed inside the rotun­da under the floor which can be accessed through an access open. TK is respect­ful­ly request­ing for accep­tance of our rotun­da design. 

Answer: The intent of the Invi­ta­tion to Bid and Pas­sen­ger Board­ing Bridge Spec­i­fi­ca­tion is not to pre­clude either man­u­fac­tur­er from propos­ing or bid­ding pas­sen­ger board­ing equip­ment engi­neered, man­u­fac­tured, and adver­tised as stan­dard base equip­ment so long as the gen­er­al oper­a­tional intent of the Invi­ta­tion to Bid and Spec­i­fi­ca­tion are met. Pre-engi­neered, man­u­fac­tured, stan­dard designs are acceptable.

Sec­tion 3.5 Man­u­als, page 18, B.

“Three note­book copies of the O & M man­u­al are required along with one (1) elec­tron­ic copy on CD, DVD, or flash drive.” 

In order to reduce our car­bon foot­print, TKAS Air­port Solu­tions would like to sub­sti­tute Elec­tron­ic Copies of the O&M man­u­al’s in lieu of hard­copies. Would the Air­port Author­i­ty be will­ing to accept this substitution?

Answer: Hard copies are required. Please com­ply with spec­i­fi­ca­tion as stated.

Ques­tion regard­ing the pho­tographs that were pro­vid­ed: Can pro­vide the DIM from the apron floor to the rotun­da floor for all three gates?

Answer: Dimen­sions are pro­vid­ed in Invi­ta­tion to Bid doc­u­ment photographs.

2.4

The cool­ing tons need­ed for a B737-800 in ECP are more than 30Ton. If you see in the calcs, the cool­ing capac­i­ty need­ed in NET terms is 112.9kW which equals 32.1 Tons NET, the PCA nom­i­nal capac­i­ty would have to be greater than that, there­fore our 45Ton mod­el is the one to be used. We are wel­com­ing the oppor­tu­ni­ty to explain this to the air­port, as we believe sup­ply­ing a 30Ton unit will become a rejec­tion by the carriers.

Answer: 30-Ton units are cur­rent­ly in use on exist­ing PBB. Spec­i­fi­ca­tion out­lines min­i­mum require­ments. The spec­i­fi­ca­tion does not pre­clude the use of oth­er, more cur­rent, stan­dard equip­ment pro­vid­ed the oper­a­tional intent of the spec­i­fi­ca­tion is met.

2.4

Hose Man­age­ment Def­i­n­i­tion, pic­tures show side mount­ed caged hose bas­ket design as well as 2‑Legged hose trol­ley sys­tem while the PBB Spec­i­fi­ca­tions state Hose Bas­ket. Ques­tion: Kind­ly advise which is the desired hose man­age­ment system.

Answer: Pro­vide Hose Basket(s) per specification.
