Will the Navy allow complete removal of the existing wall in lieu of temporary support?

As shown on CD101 There is a concrete deadman and tieback that is placed against the existing tunnel wall, this wall is to remain such that the tieback is not compromisd.

16 3/19/2020 Tunnel Drawings

N/A SD101 Is any additional as-built information available for the deadman anchor adjacent to the existing tunnel?

Only information found is provided in 1990 Dry Dock No.2 Modernization reference drawings

17 3/19/2020 Crane Rail Drawings

N/A CD101 Please provide as built information for Building 344 foundations.

N/A S-506 detail A3

Detail A3 shows a different style rail clip than detail A1. Can we use A1 detail or do you have any

The details in A3 are for a narrower clip. The clip should be coordinated with the manufacturer to fit on the plate, whereas the maximum distance from the outer edge of clips on each side does not exceed 10" further specification available for A3?

19 3/23/2020 Tunnel Drawings

N/A S-503 Detail A1

This shows a ¾” base plate on top of the crane rail base plate but lacks any other dimensions.

Are dimensions available?

Both plates are 3/4" wt. The upper base plate is shown on detail A3 /506 across the tunnel. The lower plate extends 1/2" past the web of the beam to allow for welding. The flange is 11.25" +2* (1/2")= 12.25"

No

21 3/23/2020 Crane Rail Drawings

N/A S-505 Detail A1 crane rail base plate

Would a shorter length plate be acceptable for the curve areas? The 9’ 11.5” plate shown may be too long to incorporate in to the curve areas. If so would a detail be provided?

Base plates can be reduced to 5'-11 1/2". In doing this the overall number of anchor bolts will be reduced to eight and six clips. The contractor shall consult the rail supplier for more details.

22 3/24/2020 Crane Rail Drawings

N/A SD501

Detail B3

In reference to detail B3 on plan sheet SD501 can you confirm the dimensions of the existing concrete Crane Rail foundation?

See question #2.

24 3/24/2020 Crane Rail Drawings

N/A S-104 Will the Navy consider adding a unit price pay item for rock removal to allow for potential removals needed to accommodate the new crane rail foundations?

See question #2, the intent of the sections is to minimize rock removal.

25 3/24/2020 Crane Rail Drawings

N/A V-101 Will the Navy provide additional information regarding existing Underground Utilities?

There is limited elevation information available to

Existing invert elevations have been identified.

Additionally, the notes from the manhole investigation with field notes on dimensions have been provided. Contractor will need to provide their own field verifications.

26 3/24/2020 Crane Rail Drawings

N/A V-101- V-104

Is a profile for the existing electrical duct bank available to help determine appropriate temporary support?

No existing duct bank profile has been identified.

The locations of the manholes are shown on the drawings and the existing field notes of the manholes have been provided with measurements of where the ducts come into the manhole.

Profiles in select locations can be found in the provided reference drawings. Contractor must provide their own field verifications.

27 3/24/2020 Crane Rail Drawings

N/A V-101- V-104

Will the Navy consider adding pay items for removal and replacement of existing Underground Electrical, Steam, Water, Sewer and other Utilities in conflict with Crane Rail Demolition and Replacement?

If not please further define the scope of removal and replacement.

All utilities not required to be demolished in the CD drawings, should be protected during demolition and remain in service. The cost of protection should be covered in the existing pay items, no additional pay items will be added.

28 3/24/2020 Crane Rail Drawings

N/A V-101- V-104

Does the Navy anticipate temporary shoring will be required for the existing underground electrical utilities located between the water and landside crane rails throughout the entire rail alignment from station 5+39.8 to station

The contractor must make their own determination based upon means and methods of demolition whether shoring is required.

29 3/24/2020 Tunnel Drawings

N/A S-101 Will Dry Dock 2 be dewatered during tunnel construction to a level that does not contribute to groundwater infiltration?

As a typical condition, the dry dock will be in a dewatered state. Regardless of the current state of the dry dock, the expected groundwater conditions are identified in specification 31 23 00

00.22 paragraph 1.5.b

30 3/24/2020 Tunnel Drawings

N/A Ref S-

Is it acceptable to allow freshly placed concrete for the tunnel (eg, the base slab) to become submerged due to tidal groundwater infiltration?

The contractor may submit a concrete mix designed to be durable to seawater inundation and provide an appropriate placement plan which is considerate to all noted design and building codes to be reviewed and approved.

Additionally any proposed plan must meet waterproofing materials manufacturers installation requirements. If no dewatering is provided when working in areas with tidally influenced ground water use practices such as placing concrete in the dry on a falling tide to allow for maximum time for placement of concrete and also rinse all areas with fresh water prior to placement of concrete.

34 3/24/2020 Tunnel Drawings

N/A C-102, S-506, S-502

Drawing C- 102 Note Number 3 of the Tunnel Replacement drawings calls out 8 inch Trench Drain, however Drawing S-506 of the same set and S-502 of the Crane Rail Drawings both call out 12 inch Grate. Please Clarify.

The trench width is approximately 8" with the opening on the grate at 12" dependent upon product selected. The minimum width of the trench should be 8". The grating width may vary based upon manufacturer.

NAVFAC

requiring Anti- Tamper bolts or will manufacturer recommended hex bolts be sufficient?

Trench drains must meet loading requirement of 49,000 lb wheel load grates must be suitable for this loading. Clips or manufacturer provided hex bolts are sufficient. Anti-tamper bolts should not be used.

36 3/24/2020 Crane Rail Drawings

N/A Due to lack of trench drain information will NAVFAC allow proposals to include polymer or composite pre-manufactured drain systems encased in concrete to be used on this project or is drain system required to be shaped entirely from cast-in-place concrete with embedded grate frames?

Polymer or Composite pre-manufactured trench drains are acceptable, as long as the load rating of 49,000lb wheel load is met
