DFW Airport Headquarters – Foundation package

Bidder’s questions – Addendum 02

1. Are the four (4) fire hydrants scoped in the documents to be included in this job or will they be installed as part of the South Gate plaza work? Action: Turner Omega Howard (TOH) The 4 hydrants shown on site are to be bid as part of this package.

2. What is required for the temporary water service to TOH facility? Minimum water pressure,

pipe sizing, type, and location etc. can a sketch be prepared? Action: TOH-Include a hydrant tap or meter and 200’ of 1” pvc for the jobsite trailer and 50’ of 2” copper line and a utility sink and connections, taps etc for the temporary building water as required to distribute the water for construction.

3. Are we installing a 5 ft curb inlet with one (1) 5 ft extension (per visual on drawing) or a 10 ft

curb inlet (per text on drawing)? Action: Criado Install 5ft inlet and 5 ft extension similar to Southgate work.

4. Will the Southgate Plaza site utilities be installed prior to commencement of the site utilities

package included in this scope (SA-01)? If not are we expected to carry cost for a second mobilization to complete the tie-ins? Action: TOH-The Southgate Plaza Site Utilities will be installed before the CHQ Site Utilities, Coordination meetings between both contractors will be facilitated by TOH.

5. During the prebid it was stated that the electrical scope of work was only for the office area and to be stubbed 5’ beyond the building line. Page 3A-16 Bid Package #04 – Underground Electrical and Data Conduits –Inclusions, lists much more work including work in the Garage area such as Pedestals and work shown on the Technology drawings. Please clarify what work beyond 5’ of the office area building line is to be included.

Action: TOH – To clarify, here is an overall plan of work for this site. The Office Building schedule is 14 months. The Garage schedule is 7 months. The office building sits on structural carton forms; the garage requires 12’ of over-excavation and replacement in lifts for the garage and 5’ outside the garage. The 12’ deep hole will restrict all site utilities and underground MEP in that area.

Our plan is to release all of the Site Utilities, All of the MEP under the office building slab and north and south of the building. The work that stops 5’ from the building is along column line A as the piping and conduits extend to the east towards the future parking garage structure.

Page 2 of 5

The garage area will be used for stockpiling spoils and casting beds until the tilt wall panels have been erected. The demo and haul off of the casting beds, excavation and utility and underground MEP will be bid and completed in that area at later dates.

Page 3 of 5

There are a lot of small raceways (1”, 1 ¼”, 1 ½” and 2”) in the project. Are they to be installed under the slab or can they be installed in the slab? Specs state no raceways to be installed in the slab without written permission from the structural engineer.

Action: ARI/Moye All Conduits should be bid below slab.

8. Are the Telecom underslab raceways to be installed using the “SUPERVOID” system or concrete encased as shown on the drawings?

Action: Moye & TOH: Supervoid is not applicable to the office building MEP. Trenching is to be provided per specifications, DFW guidelines, and geotechnical report. The concrete encased conduits are intended to be only those outside the envelope of the building or garage (ie. runs across the site).

9. What type raceway is permitted in the void area of the “SUPERVOID” . PVC, EMT, GRC or PVC coated GRC?

Action: ARI/Moye Supervoid is not applicable to the office building MEP.

10. The hanger detail for the raceways in the “SUPERVOID” shows stainless steel clevis hangers. Can we us fiberglass/stainless steel strut with stainless steel strut straps?

Action: ARI/Moye Supervoid is not applicable to the office building MEP.

11. What is the spec for the OSB that covers the “SUPERVOID” cages?

Action: TOH Supervoid is not applicable to the office building MEP.

Action: TOH Supervoid is not applicable to the office building MEP.

14. Drawing T2.01A shows 2 each – 1 ¼” raceways for the Type 1 floor boxes on the floor plan. The NOTES call out for 1 – 2” raceway.

MOYE RESPONSE: The correct quantity and size is (2) 1 ¼” raceways for the Type 1 floor boxes. Drawings have been updated.

15. The quantity and locations for floor boxes on Drawings E1.00 and T2.01A,B and C do not match.

Page 4 of 5

MOYE RESPONSE: Quantity and locations have been modified. Please see Addendum 02 revised drawings; T2.01A, T2.01B and T2.01C.

16. The floor boxes shown on the “T” drawings do not call for a 1” raceway for power. Is this correct?

MOYE RESPONSE: T-Series drawings do not specify raceway requirements for electrical/power. Please refer to Electrical plans for electrical conduit requirements.

17. Inclusion #12 for the electrical work (3A-16) references a MEP Matrix for equipment furnished by Turner Omega Howard. We cannot locate this matrix list.

Action: TOH – Not Applicable – Strike.

18. Will the tilt walls be formed on the slab or on casting beds? Action: HKS structures - Casting beds

19. Who will be responsible for spoils removal from the site? Action: TOH. Spoils Removal will be bid with the Earthwork and Garage Structure in the future. All spoils are to be stockpiled on site as directed by the TOH Superintendent.

20. Does the Supervoid detail apply to both the Office Building and Garage or just the Garage?

Action: TOH – Deleted, No Supervoid is required.

21. Tilt wall panels are not well detailed to reflect embeds/connections at supporting

structure. Will the panels be estimated in the shell and interiors package? Action: TOH – Please see the attached narrative from HKS.

22. Are we to include those steel embeds that are shown on the plans or leave those to be picked

up in the structural steel package which should be more complete and comprehensive? We are trying to avoid scope duplication between bids. Action: TOH – Item #4 in the Bid Package 05 is a $10,000 Material Allowance to include all miscellaneous steel embeds.

23. Please confirm that we are to include void forms, waterproofing and other similar materials

that are involved in at-grade concrete pours? Action: TOH – All Concrete materials are to be provided in Bid Package 05 – Concrete.

Page 5 of 5

24. Drawing E0.01 shows an IDF room in the Garage, but drawing E2.21.H shows a different room

layout that does not include a IDF room. Also the Technology drawings do not indicate an IDF room in the Garage. Please clarify. Action: – TOH - All work in the Garage is future and not in these Bid Packages. MOYE RESPONSE: Formal IDF rooms in the Garage have been deleted. The IDF function is taking place with the (2) pedestals/enclosures shown on the north and south sides of the Garage.

25. The Technology series drawings show (11) more floor boxes than the electrical drawings (8

more on T2.01.A, 1 more on T2.01.b and 2 more on T2.01.C). Which is correct? MOYE RESPONSE: Quantity and locations have been modified. Please see Addendum 02 revised drawings; T2.01A, T2.01B and T2.01C.
