Terminal E Renovation and Enhancements

1. In the Customer specification 13041, item 2.3 A., page 4, states the existing serialnumber for both the “Storage Facility – E8A and E8B” bridge as 38777. Should theE8A bridge serial number be identified as “38776” (an A3 64/131) and the E8Bbridge serial number be identified as “38777” (an A3 68/141)? Please clarify.

Per Massport’s existing equipment inventory table, Gate E8A is S/N 38776 Jet-way A3-64/131 and Gate E8B is S/N 38777 Jetway A3-68/141.

2. In the Customer specification 13041, item 2.13 A., page 16, states A ramp servicedoor, landing, and service stair shall be provided at the aircraft end of the bridge orwalkway for apron access by authorized personnel. These shall be positioned perthe engineers designated location. (Pre-Bid discussion meeting). The Customerdrawings, identified as PL.801 PL.802, depict the PBB1 (inboard) position with theservice stair/landing coming from the fixed walkway/corridor section at the terminalend and the PBB2 (outboard) position does not show a service stair on the bridge atall. Do you want us to quote to have a right-side service door and landing along witha maintenance access ladder, but no stair, on the “new” PBB2 (outboard) bridgepositons? Do you want us to quote to place a service door, landing, and stairassembly in the “new” walkway/corridors? Please clarify.

Per Drawings PL.801 and PL.802, no service door, landing, or maintenance ac-cess ladder for upper-deck PBB2. A service door, landing, and baggage con-veyance shall be mounted to the new fixed walkway of INS-level PBB1.

3. In reviewing the Customer drawing, identified as PL.801, the PBB # 2 position bridgewill only be used to service the A380-U1 (upper-deck) door position. Pleaseconfirm that this is correct and that the PBB # 2 bridge will not be used to serviceany other aircraft.

We are only depicting PBB2 docked to the A380 because the slope is not withinADA slope compliance for unassisted access for all other widebody aircraft.Massport or the tenant may want to use assisted access for the greater than al-lowable slope conditions; therefore, the bidder shouldassume the PBB will be used for other widebody aircraft. We as thedesigner cannot release a PBB design document or recommend a scenario thatdoes not comply with the standard, and relies on an operationalrestriction.

EXTENSION OF QUOTES DUE DATE:

4. In reviewing the Customer drawing, identified as PL.801, the “AIRSIDEEQUIPMENT SCHEDULE” has a column identified as “REQUIRED PBBOPERATIONAL RANGE”. Please confirm how this range is defined; is it measuredfrom rotunda-pivot to cab-pivot or is it measured from rotunda-pivot to end of the cabbumper? Based upon the size of the existing bridges for the PBB # 1 bridge, itwould appear that the range is measured from the rotunda-pivot to the cab-pivot. Please note the following:

Measured from rotunda-pivit to cab-pivit.

a. The Gate E10 and E12 PBB # 2 bridge are listed with a “REQUIRED PBBOPERATIONAL RANGE” of 58’-131’. This would require a travel range of 73feet, JBT-Jetway does not have a 3-tunnel bridge that can satisfy this rangeof travel and meet both the retract and extend dimension regardless of how itis measured.

Bidder shall recommend alternate/comparable 3-tunnel PBB model for ap-proval, which accommodates the design aircraft fleet mix.

b. The Gate E11 PBB # 2 bridge is listed with a “REQUIRED PBBOPERATIONAL RANGE” of 45’-92’. This would require a travel range of 47feet, JBT-Jetway does not have a 3-tunnel bridge that can satisfy this rangeof travel and meet both the retract and extend dimension regardless of how itis measured.

Bidder shall recommend alternate/comparable 3-tunnel PBB model for ap-proval, which accommodates the design aircraft fleet mix.

5. Please consider providing AutoCAD drawing file of the project gates, etc. andallowing the bridge manufacturers to define and quote the bridge models that wouldwork with your aircraft layout as represented on the Customer drawing PL.801. CAD

file attached.

Currently, the answers to questions and requests are due to come out by Addendum on14 Dec 2015. We’ll need to send our quote out very shortly after (16 Dec) in order tohave it arrive on time. In light of the important technical and commercial questions thatwe’re hoping to have answered in that Addendum, we respectfully request an extensionto the bids-due-date to perhaps 23 Dec 2015 so that we may have enough time toprocess that new information.

Massport has decided to extend the due-date to December 23, 2015, see Adden-dum 1.

identified. Can more information please be provided for these sensors?

Response – The sensor manufacturer will ensure the commissioning and installation of all

sensors. Please see Addendum 1 and attached Smart Sensor product datasheet.

2. On Drawing PL.802 there is a requirement for a baggage conveyor mounted to the service

stairs, but in Section 13041‐16, 2.13 Service Door, Landing and Stair it mentions a

requirement for a wheel chair lift and late bag slide to be mounted to the service stair

landing.

Q: There seems to be a conflict with the requirements. Please advise as to what is to be

required and where.

Response – Contractor shall provide a wheel chair lift and bag slide at the landing, which is

attached to the fixed walkway tunnel.

3. On Drawing PL.802, the service stairs and landing are depicted to be mounted at the

walkway and not on the PBB.

Q: Is the requirement of relocating the service stairs/landing to be typical of ALL PBB’s at each

gate, including the Refurbished/Relocated PBB’s?

Response – Please reference General Note 3. The service stair, landing, and baggage

conveyance are only mounted to the INS level PBBs (refurbished/relocated PBBs). The club

Date: December 10, 2015





4. Please confirm that a point‐of‐use pre‐conditioned air unit is to be mounted at the rotunda

with a telescoping air duct and flexible air ducting connecting to the hose management

system and not a point‐of‐use PCA unit mounted at the outermost tunnel section with

flexible ducting connecting to the hose management system?

a. Please confirm that this is to be typical of ALL PBB’s at each gate, including the

Refurbished/Relocated PBB’s.

Response – All PCA units are to be mounted on rotunda column per specifications.

See item 5 below.

5. Please confirm that ALL PBB’s at each gate are to have 120 Ton PCA units with two hose

management system units each, including the Refurbished/Relocated PBB’s.

a. Also, would this require two telescoping ducts per PBB since the PCA units are dual

output?

Response – Correct. Two 120 ELT PCA units, two hose management systems. One

telescoping air duct with a two connector splitter.

6. Please confirm who is responsible for the supply and installation of the bollards depicted in

Drawing PL.802. If we, as the bidder, are required to supply and install the bollards, can the

structural drawings please be provided as stated? Please confirm if the bollards are just to be

With shrinking budgets and growing costs, airports of all

sizes, now more than ever, need to leverage their existing

resources to improve operational performance and

travelers’ experiences.

Assets are not the same. Even if they start out the same,

they are used differently. The different usage greatly

affects their life expectancy. If the usage profile is not

taken into account, assets can fail unexpectedly hurting

operational performance and travelers’ experiences.

Brown Technologies, with its AB500 series Smart Sensors

and Analytics Platform, installs sensors that monitors

motors, rollers and other industrial equipment.

The AB500 Series Smart Sensors monitors temperature,

vibration, volts and amps as well as other operational

parameters.

The Analytics Platform analyzes in real time the sensors

and understands the usage profile for each equipment

and the impact that profile has on asset life. The Analytics

Platform leverages Machine Learning to understand the

different usage profiles of each equipment and how they

contribute to the overall life and efficiency of each asset.

The system scales from one asset to hundreds of

thousands of assets.
