REQUEST FOR ALTERNATE

1. Alternate Pricing for Reduced Work Schedule Provide alternate pricing for completing the project within 365 calendar days for Substantial Completion and 90 days for Final Completion.

BAGGAGE HANDLING SYSTEM

1. Clarification: The bid form has 405 days for substantial completion and 90 days for finial (sic) completion. The BHSC section does not have EDS testing complete for two years after NTP. Which requirement is the correct requirement that governs the schedule? If the Bid form dates are correct, how is the testing going to be adjusted to meet the schedule and the specification requirements? Response: Overall construction duration for the project is 405 calendar days for substantial completion followed by 90 days for final completion. All equipment will need to be tested and ready by substantial completion. Refer to General Requirements Section 01010 Summary of Work Part 1 – General 1.5 - HOURS OF WORK.

2. Clarification: Reference page 14520-5, Item 21. Does this standby period apply to the re-control scope of work, or the EDS scope of work, or both? Please clarify the standby requirements. Response: Both, BHSC will be responsible for personnel in the Control room to perform immediate repairs to the computer and PLC code or field trouble shooting needs as required for that operational day.

3. Clarification: Reference page 14520-197, Item B.2.c. Typically, shaft encoders are not used on queues and merges. Please confirm whether or not this is acceptable. Also, is a shaft encoder with 3 pulses per revolution acceptable? Response: Bid per Contract documents . System design must pass required tests for CAGE and Battelle.

ATSAC II Terminal A In-Line EDS – Contract No. 9500313 01/10/08 ADDENDUM No. 3 Page 2 of 23 4. Clarification: Reference page 14530-261, Item 3.7.B. Is this support required for the entire operational day, or only for a certain period of time? Please clarify. Response: Day time system operation consists of the entire operational day.

5. Clarification: Reference page 14530-261, Item 3.7.B. Is this support required after a night of testing, when no changes are made to the MCPs, other than switching from one I/O system to the other? Please clarify. Response: Yes

6. Clarification: Reference page 14530-272, Item 8. This phasing plan outlines an overall schedule in excess of 2 years (exact duration is unknown, since details are not provided for phases 5 and 6). In the bid form and at the bidder’s meeting it was indicated that the schedule was 405 days long, with an additional 90 days for standby. Please clarify the schedule for this project. Response: Overall construction duration for the project is 405 calendar days for substantial completion followed by 90 days for final completion. All equipment will need to be tested and ready by substantial completion.

7. Clarification: For the re-controlled MCPs, is it sufficient to provide markup sheets for the new I/O or will completely new MCP schematics be required? Response: BHSC will receive Auto Cad drawings that must be updated with the changes. Mark-up sheets will not be accepted.

8. Clarification: Do motor disconnect require an auxiliary monitoring contact? Response: If devices are supplied with auxiliary contacts on disconnect switches they must be used. See spec section 3.6.H.2.through .5

9. Clarification: Per item 3 in Addendum 2, “The BHSC shall contract TransSolutions to model their design changes to the legacy system. The minimum requirements developed in the models shall be met.” Please explain what changes are expected to be made to the legacy system that will require system modeling? It will be difficult to define a scope of work to TransSolutions in order to obtain accurate pricing for this work if we do not have a description of the changes to be performed. Response: It is up the BHSC to determine changes required

10. Clarification: Since TransSolutions has been specified by the Owner to perform the work and have already performed the original system modeling, will they provide an identical fixed price to all BHSC contractors to perform this modeling? Response: The BHSC will be required to provide modeling for the project. An allowance of $50,000 is to be included in the base price for this work. The BHSC may, but is not required to use TransSolutions for modeling.

11. Clarification: Spec 14520 Section 2.3 E.13.6 specifies the following “6) Photocell reflectors shall be mounted using a pocket that keeps the reflector tight to the side of the conveyor. a) The reflector shall be sized as such to fill the side guard opening. Could a detail be provided of what is expected and how the ATSAC II Terminal A In-Line EDS – Contract No. 9500313 01/10/08 ADDENDUM No. 3 Page 3 of 23 reflector is to “fill” the opening? Is it expected that the reflector will be flush with the face of the side guard with no gaps? Response: Pocket should be designed to allow minimal movement of the reflector. Holes for reflector and photo eyes are to be dimpled.

12. Clarification: Spec. 14520 Section 3.1.3 calls for “Vibration Abatement-The BHSC is required to submit specifications for vibration dampening and isolation material that are planned for use on this project to the Owner's Representative”. Does the Owner have a requirement for vibration isolation on all conveyors, both floor supported and ceiling supported? If so, please provide the method for measuring successful vibration isolation? If the BHSC determines that there will not be vibration in excess of the specified level, could vibration isolation be eliminated? The specification only requires the identification of conveyors in the frequency range of 8 to 20 Hz. This does not necessarily mean that this frequency will be transferred to the building therefore a measuring criteria would be helpful. Response: Refer the spec section 1.8.M.3

13. Clarification: It is identified that the BHSC is responsible for employee parking and transportation. Does the Owner have any available off-site parking areas which may be used to for workers to park and where the contractor can transport the workers to the site? Response: Parking will be available to the contractors at the ADE Building at no cost. The address is 3003 South Service Road, DFW International Airport.

14. Clarification: Spec 14520 Section 2.3.K.6 states “Spares – the BHSC shall supply spare processors and memory modules for the type of PLC used, programmed with the actual operating programs for each PLC and memory module in actual use of the operating controller”. This appears to require that a spare PLC is required for every PLC. We request a clarification as to the number of spares required and is this paid for separately under spares or to be included in the base price? Response: Change 2.3.K.6 to read: Spares-the BHSC shall supply spare processors and memory Modules for the type of PLC used at a minimum of 10% see Section 2.5.J.1.f.9

Minimum stock levels will be kept at the Airport to insure effective and efficient repair of any equipment. The BHSC through its warranty agreement must be able to provide spare parts for all equipment in a short time frame, in order to replenish this stock as well as have parts on hand which the Owner did not choose to purchase. An allowance of $500,000 is to be included in the base price for spare parts.

15. Clarification: Spec 14520 states that “conduit mounted below seven feet – six inches in height must be of the rigid type”. Does this mean only from the ground surface and main platform, or is conduit running along a catwalk also considered to be below 7’-6”? Please clarify where the 7 ‘-6” will be measured from. Response: 7’-6” will be measured from finished floor.

16. Clarification: Spec 14520 Section 2.2.I.4.b states “conveyor identification must be stenciled on a minimum of ten foot centers. How is the ten foot centers measured? Does this mean there cannot be greater than 10 feet between conveyor IDs? Does this mean that it must be every 10 feet on both sides of the conveyor? This is abnormal for a typical BHS project and would essentially require that every 10 foot conveyor bed must be labeled on both sides if strictly interpreted? Response: ATSAC II Terminal A In-Line EDS – Contract No. 9500313 01/10/08 ADDENDUM No. 3 Page 4 of 23 Remove 2.2.I.4.b Conveyor identification must be stenciled on a minimum of ten foot centers.

Change 2.2.I.4.c The identification must be located on the conveyor where it is easily viewed from the ground, catwalk or platform. Minimum ID placement is on drive sections and head and tail ends of each conveyor.

Change 2.2.I.4.d On queues and taper rollers the ID shall be in two inch characters in a conspicuous location on the conveyor or device.

17. Clarification: Specification 14520 states “All conveyors shall be adequately sway-braced in lateral and longitudinal directions, and in a manner that meets or exceeds local seismic regulations and codes. a) Spacing-must-not exceed 20 feet. b) All sway bracing connections and points or attachment must be through-bolted rather than through-welded.” Will the Owner accept as an alternate a detail for a welded connection for the sway bracing provided it is performed by a certified welder? Also, will it be acceptable to use a cutting torch to make the holes for the through-bolted connection? Response: No follow specification 2.2.D.4.b

18. Clarification: Spec 14520 Section 2.2.B.3.C states “All conveyor bed section Horizontal and Vertical butt coupling joints shall be bolted together”. Will the Owner accept as an alternate a Horizontal joint which is not bolted, but rather has a chamfered edge on both of the adjoining conveyor beds? If accepted, it would be certified that the conveyor would carry the specified loads. Response: Follow Specification section 2.2.B.3.d and e.

19. Clarification: For the sort controller application, what will be the source of the BSMs and the FIDS (ie. ARINC, SIDA, SABRE)? Response: EDS/SABRE

20. Clarification: Spec 14520 Section 1.1.I 18 states “The BHSC shall ensure that the overall BHS operates efficiently and effectively in concert with the EDS screening matrix. There are potential differences in baggage processing rates between the existing BHS conveyors feeding the EDS matrix and the EDS matrix itself. Changes will be required to the larger, legacy BHS such as, additional queues, brake motors, clutch/brakes or VFDs, or other modifications”. Through the bid process, it is impossible for the BHSC to determine if any additional equipment will be required as stated above. It would be expected that the BHSC would bid the project per the equipment on the bid drawings. If it is determined at a later date that additional equipment is required, will the Owner cover this as a change order? Response: The BHSC is responsible for providing a Bid inclusive of any modifications.

21. Clarification: Spec 14520 Section 1.1.J.9 states “The re-control process of the existing system shall be completed and tested to meet all specification requirements prior to any tie-in's or interface with new systems. All system issues and deficiencies shall be resolved before any interfacing to new system shall be corrected”. Can it be clarified that the existing legacy system is currently operating to the new specification requirements? Otherwise, if the system is not meeting the new specification requirements, could the known deficiencies be identified (such as throughput rates, merge logic, baggage jams, etc.)? ATSAC II Terminal A In-Line EDS – Contract No. 9500313 01/10/08 ADDENDUM No. 3 Page 5 of 23 Without identifying any deficiencies, it would be expected that the existing PLC ladder logic will be acceptable to re-use. Response: Refer to Specification section 3.6 for system functionality, both the re-control and EDS portions of code will be consistent to this Specification section.

22. Clarification: Clarification is requested on the intent of the “Re-control Project”. The understanding is that Re-control refers to replacing the legacy system hardware with matching PLC and PLC I/O hardware used in the new project. This does not mean that the BHSC is expected to “Re-program” the existing legacy BHS. Please verify that the existing PLC ladder logic will be available to download to the new PLC hardware? Response: Refer to Specification section 3.6 for system functionality, both the re-control and EDS portions of code will be consistent to this Specification section.

23. Clarification: Spec 14520 Section 3.7.A states “The BHSC shall be responsible for field verification of existing site equipment, configurations, MCP wiring identification, conditions, and controls prior to starting design, manufacture, modification and installation activities. The BHSC shall be responsible for ensuring current control drawings are correct and Final As-Built drawings after re-control activities are accurate”. Does this mean that the BHSC is responsible to verify the conditions are accurate prior to placing our bid? How is the BHSC to identify the potential scope of work required to correct drawings that may not be accurate at this current date? Will the Owner accept a change order if the drawings are identified to be incorrect? Response: American Airlines has contracted G&T Conveyor to update all out-bound MCP drawings; these updated drawings are available through MS Dallas. BHSC will be required to update these drawings for re-controls. The owner will not accept change orders if drawings are incorrect.

24. Clarification: Spec 14520 Section 3.7.A.12 states “The BHSC is responsible for reprogramming the integration of the existing system. The BHSC will provide a comprehensive report detailing any deficiencies, if any, in the existing system, be it mechanical or electrical hardware.” Could you please provide clarification as to what the first sentence requires - “responsible for reprogramming the integration of the existing system.” Does this infer that the BHSC is responsible for reprogramming the entire legacy BHS, or does this infer that the BHSC is responsible to reprogram the integration between the existing and the new systems? Response: Refer to Specification section 3.6 for system functionality, both the re-control and EDS portions of code will be consistent to this Specification section.

25. Clarification: Section 3.7.A.12 states “The BHSC is responsible for reprogramming the integration of the existing system. The BHSC will provide a comprehensive report detailing any deficiencies, if any, in the existing system, be it mechanical or electrical hardware.” With respect to the second sentence where “The BHSC will provide a comprehensive report detailing any deficiencies”, after this report is prepared, and if there are deficiencies that are found, will these deficiencies be requested to be fixed? If so, will the Owner pay for the correction to these deficiencies through a change order? Secondly, does this require that the BHSC spend extensive time observing the system before beginning the Re-control Process so as not to be responsible for existing deficiencies? Does this mean that it would be best/required to first perform a full system test of the existing legacy BHS before beginning the Re-control process? If we are to use the existing PLC ladder logic, a simple replacement of the PLC hardware would not cause deficiencies to the existing system performance. Response: Refer to Specification section 3.6 for system functionality, both the re-control and EDS portions of code will be consistent to this Specification section.

ATSAC II Terminal A In-Line EDS – Contract No. 9500313 01/10/08 ADDENDUM No. 3 Page 6 of 23 26. Clarification: If it is the intention that the existing legacy BHS is to be re-programmed, then will the Owner provide a full set of detailed BHS drawings for this system? Also if there is a detailed written Description of Operations for the existing system (as described and required in the current specification), we would also request it be provided so that the system could be re-programmed. Response: Refer to Specification section 3.6 for system functionality, both the re-control and EDS portions of code will be consistent to this Specification section. American Airlines has contracted G&T Conveyor to update all out-bound MCP drawings; these updated drawings are available through MS Dallas. BHSC will be required to update these drawings for re-controls.

27. Clarification: Spec 14520 Section 3.10.10 requires a video on DVD of all subjects covered in the on-site training sessions. Is it acceptable to have the on-site training classes recorded and turned into a training video? Response: Yes, editing will be required to keep video on a professional level.

28. Clarification: Spec 14520 Section 1.11.D.4.c states “If the baggage handling contractor has cause to believe item(s) may require stocking pursuant to the terms and conditions of warranty provisions that the Owner and/or Owner's Representative declines to stock, the BHSC shall stock such long lead items separately at no cost to the Owner and/or Owner's Representative. In no case shall the absence of appropriate spare parts be construed in any way to abridge or interfere with the responsibilities of the BHSC for warranty services as defined herein”. It is nearly impossible to estimate which spare parts the Owner will purchase. This places the burden on the BHSC to purchase and stock parts for the Owner’s benefit with no clearly defined value. We request that the Owner give an allowance for the spare parts that the BHSC should carry. If no value is given, is it possible for the Owner to identify what has been purchased for spare parts on previous projects in comparison to the recommended spare parts list? In Section 3.11.B.3, it is stated that the BHSC may not receive Conditional Acceptance until the BHSC has stocked the spares that the Owner does not purchase. Response: The BHSC needs to stock a full compliment of spare parts for all equipment during the warranty period.

29. Clarification: When the warranty period is over, will the Owner purchase the spare parts from the BHSC that the Owner did not purchase initially? If not, then these parts will be out of warranty with the manufacturer and would no longer be considered as new on a future project. Under these circumstances, will the Owner consider deleting this requirement of “Unknown Quantity” as this will only raise the bid by an amount to cover this estimated cost? Response: Minimum stock levels will be kept at the Airport to insure effective and efficient repair of any equipment. The BHSC through its warranty agreement must be able to provide spare parts for all equipment in a short time frame, in order to replenish this stock as well as have parts on hand which the Owner did not choose to purchase. An allowance of $500,000 is to be included in the base price for spare parts.

30. Clarification: Reference page 14520-62, Item O.6. Can the disconnects for the motor and clutch/brake be two separate devices or must they be combined into one disconnect? Response: Motor and clutch/brakes shall have separated disconnects.

31. Clarification: ATSAC II Terminal A In-Line EDS – Contract No. 9500313 01/10/08 ADDENDUM No. 3 Page 7 of 23 Reference page 14520-102, Item 3.a. Is the Warner CBC-150 conduit mounted clutch/brake power supply acceptable for this project? Response: No

32. Clarification: Reference page 14520-123, Item I. This item states that communication cable must be redundant. Does this require the use of redundant media Allen Bradley CNBR ControlNet adapters and redundant ControlNet coax for all remote I/O? Response: Redundant cables are required. Labeling and testing of these cables must follow specifications.

33. Clarification: Reference 14520 and Drawings. The description of operation describes illuminated start pushbuttons on all control stations. Also, all current new designs at DFW utilize illuminated start pushbuttons on all control stations. The control station details on the contract drawings show non illuminated start pushbuttons. Please confirm that illuminated start pushbuttons are required for all control stations. Response: Existing control station start push buttons will remain non-illuminated. All new start push buttons will be illuminated. Drawing change required B7.003

34. Clarification: Addendum 2, Page 1, Item 3. part 37 adds the requirement to utilize TransSolutions to provide modeling services of the existing system. Our interpretation of this requirement is that this is an extension of Item 18 on page 5 for the ticket counter feed conveyors. Please confirm our interpretation of this. Also, please confirm that this new requirement is not part of the outbound sortation re-controls work. Response: This requirement applies to the entire system. Required changes determined by BHSC engineering staff will be modeled by the BHSC and is not required to use TransSolutions for modeling. .

35. Clarification: Spec section 14520, page 4, Item 7 states, “It is the responsibility of the BHSC for this project to identify and report any obstacle involving the building or other relevant infrastructure that may adversely affect the completion of this project. Any modifications or other changes to these facilities that are necessary must be reported to the Owner in the contract bid. Failure to do so will result in the BHSC taking full responsibility, financial and otherwise, for the modifications.” We have not found a vehicle within the bidding documents to provide this. Also, it seems that the architectural and structural drawings have performed the requested obstacle identification. Response: This is the vehicle to notify the owner of such obstacles. First sentence states “It is the responsibility of the BHSC” Reference drawing B9.002 detail for obstruction free zone as one of the guidelines.

36. Clarification: Reference Page 8 of Addendum #2, Clarification # 58 and Specification section 14520, page 272, item 8. There is a discrepancy between these 2 specification sections. Spec section 14520 places the BHS / Battelle testing after substantial completion of the Baggage Handling System’s (24 months after NTP). Please confirm whether or not the testing is to occur after the 405 substantial completion time indicated in the Summary of Bid. Response: Overall construction duration for the project is 405 calendar days for substantial completion followed by 90 days for final completion. All equipment will need to be tested and ready by substantial completion.

ATSAC II Terminal A In-Line EDS – Contract No. 9500313 01/10/08 ADDENDUM No. 3 Page 8 of 23 37. Clarification to Add No. 2 Per item 3 in Addendum 2, “The BHSC shall contract TransSolutions to model their design changes to the legacy system. The minimum requirements developed in the models shall be met.” Please explain what changes are expected to be made to the legacy system that will require system modeling? It will be difficult to define a scope of work to TransSolutions in order to obtain accurate pricing for this work if we do not have a description of the changes to be performed. Response: The BHSC will be required to provide modeling for the project. An allowance of $50,000 is to be included in the base price for this work. The BHSC may, but is not required to use TransSolutions for modeling.

38. Reference page 14520 Change 2.5.J.1.f.1 to read: All development software and licensing rights. (Password protected)

39. Reference Section 14520 Add to 2.5.j.1.f.9: All PLC programs will have the current loadable programs stored on this machine and a soft copy will reside in the control room during the warranty period. It will be the BHSC responsibility to maintain these back-up copies.
