Additional Questions and Answers + Lift Table

1. What is the maximum allowable setup radius or distance from the crane outriggers/pads to the center of gravity (CG) of the F-15 airframe and KC-135 nose section at Building 1708? Offerors require this dimension to verify load chart capacity and boom angle clearance at the mandatory 50-foot lift height. See Attachment 4- Question 9 for answer.

2. Will the Government provide the aircraft-specific lifting slings, spreader bars, and attachment hardware as GFE pursuant to TO 00-80C-1, or is the contractor required to furnish specialized spreader bars? All spreader bars, lifting slings and rigging equipment are government procured and provided.

3. Are there any physical footprint or overhead obstruction limits at Building 1708 that restrict positioning a standard 50-ton mobile/truck-mounted crane? There are no physical limitations or obstructions at building 1708.

4. What time should the crane and operator typically be expected to arrive and be ready for operations onsite? Crane and operator should be in place and prepared to lift no later than 0730.

5. What is the anticipated completion/release time for the crane each service day? On service days, crane operations should cease at 1130.

6. Should contractors price each occurrence based on a full 8-hour shift, or is the crane only expected to remain onsite for the time necessary to complete the KC-135 and F-15 lifting evolutions? Quote should be based on half-day increments, as the crane will not need to remain on site following the KC-135 and F-15 lifts (approximately 4 hours).

7. If the lifting activities are completed earlier than anticipated, would the crane/operator be released upon completion, or expected to remain onsite for the full scheduled period? Equipment and operator are only needed on site for the duration of the lifting operation.

8. Is there an estimated number of working/standby hours per service occurrence that contractors should use for pricing purposes? Per service occurrence, contractors should anticipate approximately 4 working hours (0730L-1130L)

9. Based on the load data provided (F-15: 33,000 lbs gross / 31,600 lbs net; KC-135 nose: 8,700 lbs gross / 6,850 lbs net) and the lift heights specified (36" for the F-15, 72" for the KC-135 nose), we need to confirm the required lift radius to determine whether a 50-ton crane has sufficient capacity, or whether a larger crane (75-ton) will be needed to safely execute the lift per T.O. 00-80C-Specifically, could you provide or confirm:

a. The maximum distance the crane can be positioned from the aircraft's center of gravity at the Sheppard AFB Annex, Building 1708 lift site (i.e., available boom setdown area/site constraints)

b. Any ground clearance or obstruction limitations around the lift location

For the required lift radius, we have no direct guidance for positioning the crane for the F-15 lift, and boom setdown/swing areas will be largely determined by the available crane. Currently, we park approximately 30ft from the aircraft CG and have no reason to swing the boom beyond the building (the only potential site constraint) from that parking spot. I have attached the lifting chart for the KC-135, though the charts only give information for a 75T, 140T and 250T crane. There are no ground clearance issues at either site.

10. Does each of the 29 annual service events include both the KC-135 nose lift and the F-15 airframe lift? Each service event will include the KC-135 nose lift, as well as the F-15 lift.

11. Should offerors price each event as one mobilization supporting two aircraft lifts?

Each mobilization will consist of both aircraft lifts. Offerors should make bid based upon a single mobilization consisting of two aircraft lifts.

12. How many crane and operator hours should be included per scheduled event? Each scheduled event should last approximately 4 hours. We are prepared to lift no later than 0730 and lift operations should cease around 1130.

13. What is the maximum anticipated operating radius for the 33,000-pound F-15 lift?

We have no direct guidance for operating radius on the F-15. Currently, we park approximately 30ft from the aircraft’s center of gravity and lift is completed almost exclusively with the hoist. Radius will be largely dependent on crane dimensions and clearance to nearest building.

14. Will the Government provide the aircraft-specific lifting slings, spreader bars, shackles, and other rigging equipment required by the applicable technical orders?

All spreader bars, slings and other rigging equipment are government owned and provided.

15. Is the contractor required to provide outrigger mats or other ground-protection materials? Contractor is required to supply some form of outrigger protection.

16. May an offeror provide a crane with a capacity greater than 50 tons if necessary to satisfy the applicable load chart at the required operating radius? Where necessary to meet safety requirements, a larger crane may be offered.

17. Are operator background checks, base-access credentials, or other installation-access requirements applicable? After completion of a background check, members may be included on an EAL (Entry Authorization List). Further documentation such as contract data, personal data and valid photo ID’s may be required for the EAL.

18. How will cancellations, schedule changes, or delays after crane mobilization be handled? Our only limiting factor is weather, so we do our best to forecast this 48 hours in advance. We maintain contact through contractors preferred method to alleviate any potential delays.

19. Should mobilization, demobilization, travel, fuel, standby time, and all other costs be included in the firm-fixed unit price for each event? Yes, all costs should be captured in the lift rate as that is the total amount that the government will pay per lift. There will be no other payment/reimbursement. Contractors are free to invoice as soon as lift has been completed.

20. Is subcontracting the crane and certified operator permitted when the small-business prime contractor retains responsibility for contract management and performance? Yes, subcontracting is permitted.

21. Is there an incumbent contractor or historical unit-price information available for this requirement? The incumbent contractor is B.W. Strayhorn. We do not provide unit pricing but the total dollar amount of the original contract (FA302021P0088) was $254,906.
