8. What are the anticipated Head Injury Criteria Ratings for the designed Protective Surfacing at the Rappelling Tower, The Obstacle Course and the Martial Arts?

RESP: Paragraph 1.2.2 Head Injury Criteria (HIC) from specification Section 32 18 16.13 will be deleted. See forthcoming amendment.

9. Are Stair nosings (see detail C4 on A-501) required for the Bleacher walkways (see A1 on A- 202)? Also see drawing details A4 & B1 on S-403 and A1 on S-503 where nosings are not indicated.

RESP: No.

RESP: No.

11. Notes on detail B1 and B3 on Drawing A-106 identify the Stair Landings in the Rappelling Tower as being precast. Structural Details A1, C-4 and D4 on drawing S-407 indicate Cast In Place Construction. Is NAVFAC open to both concepts?

RESP: Follow details on S-407 for Cast-in-Place construction. See forthcoming amendment.

12. Specification Section 03 30 00 paragraph 2.4.3.2 calls out abrasive aggregate products for use with a Nonslip Aggregate Finish. Where is this finish to be used?

RESP: Nonslip aggregate finishes may be used where “WR-1” finishes are specified on Architectural Drawings (A-001) for horizontal surfaces.

13. Section 03 30 00 paragraph 2.6 REINFORCEMENT mentions “coated reinforcement” in paragraph 2.6b. Please clarify your requirements for coated reinforcing steel, if any.

RESP: Reinforcing Steel is not coated on this project. See forthcoming amendment.

14. Section 03 30 00 paragraph 2.6 REINFORCEMENT mentions in paragraph 2.6.2b and 2.6.2c mention galvanizing, dielectric material and epoxy coating in the discussion about Mechanical Reinforcing Bar Connectors. Please clarify your requirements for coatings on mechanical connectors.

RESP: Mechanical Reinforcing Bar Connectors are not coated on this project. See forthcoming amendment.

15. Section 03 30 00 paragraph 3.2.3 Subgrade Under Slabs on Ground mentions “capillary water barrier under interior slabs on ground”. Section 31 23 00.00 20 EXCAVATION and FILL describe POROUS FILL FOR CAPILLARY WATER BARRIER in paragraph 2.2 and again in paragraph 3.5.5. Please confirm these are the specifications for “capillary water barrier”.

RESP: Yes, this is the specification for the capillary water barrier. It shall be used under vapor barriers that are specified in interior/enclosed spaces. See response to #16 below for these locations.

16. Please confirm that capillary barrier and vapor barrier are required under all building slabs per Section 03 30 00 paragraph 3.4.2, whether enclosed or open air and strike “interior” from paragraph 3.2. 3.

RESP: Capillary Barrier/Vapor Barrier are required only under slabs in “interior” spaces. This includes the enclosed space in the Covered Training Area (south of gridline C-B) and the entire enclosed space under the Bleachers. There is no Capillary Barrier and Vapor Barrier for the Rappelling Tower structure.

17. On Drawing S-001 CONCRETE NOTES, Note A mentions Specification Section 03 31 30 MARINE CONCRETE. Please confirm the reference to Marine Concrete can be struck the note.

RESP: For Drawing S-001 CONCRETE NOTES, Note A, Omit “SEE SPECIFICATION SECTION 03 31 30 MARINE CONCRETE FOR REQUIREMENTS” and Replace it with “SEE

SPECIFICATION SECTION 03 30 00 CAST-IN-PLACE CONCRETE FOR

REQUIREMENTS”. See forthcoming amendment.

18. Please clarify the requirements for detail A1 on S-508: TIE DOWN ANCHOR DETAIL.

These devices are not depicted on drawing details A1 and A3 on S-105. We see perhaps 10 anchors at the 60 ft deck (A4 on S302). Please confirm there are no anchors at the “HELL HOLE” or on the 30 ft rappelling deck.

RESP: TIE DOWN ANCHOR DETAIL (A1/S-508) is applicable to the 30ft level and 60ft level of the Rappelling Tower. For Tie down anchors, follow Architectural drawings for the correct locations. There are five (5) anchors on the 30ft platform (see B3/A-106) and there are ten (10) anchors on the 60ft platform (see B1/A-106). Note that A1/S-105 does not show the anchors (it needs to be added), refer to B3/A-106. See forthcoming amendment.

19. We don’t see any tie off points on the OPTION 3 roof at the Rappelling exercise or on the Covered Teaching roof on S-101 or on the Option 2 Bleacher roof on S-103. Please confirm no tie offs are required at these areas.

RESP: Correct, there are no tie off points (TIE DOWN ANCHOR DETAIL A1/S-508) for the OPTION 3 Rappelling Tower roof, nor the OPTION 2 Bleacher Roof, nor the Covered Training Roof on S-101.

20. Section 31 23 00.00 20, paragraph 1.5 CRITERIA FOR BIDDING: Drawings B-701 through B-705 Boring Logs are not provided. Bedrock Determination Maps are provided with specification 01 57 19.01 30. Please confirm the site will be delivered graded to the elevations depicted on drawing C-100. Topsoil is specified in Section 32 92 19 SEEDING

RESP: Confirmed, the site will be graded to the elevations shown on DWG C-100.

21. Drawing Detail D2 on CS501 provides the cross section for the PCC PAVEMENT Service Road found on drawing CP101 and CP102. The Cross Section Detail describes a 6” DRAINAGE LAYER over a 6” BASE COURSE. Please clarify the material to be used for BASE COURSE under the asphalt treated drainage layer: is it to be Aggregate Base Course (ABC) specified in 32 11 23 paragraph 1.2.1 and 2.1.1.1 or Graded Crushed Aggregate Base Course (GCA) specified in paragraph 1.2.2 and 2.1.1.2?

RESP: The 6” Base Course material shall meet the requirements for Aggregate Base Course specified in Section 32 11 23, Par 1.1 and 2.1.1.1.

22. Section 32 16 19 Specifies Detectable Warning Systems in paragraph 2.7 and again in paragraph 3.10. None are shown on contract plans. Please confirm none are required. See Drawings CG103

RESP: Detectable Warning Systems are not required. See forthcoming amendment.

23. Reference Factor 1 Experience:

RELEVANT CONSTRUCTION PROJECT: For purposes of this evaluation, a recent relevant construction project is defined as follows: New construction of cast-in-place reinforced concrete structures/buildings that resist seismic (Seismic Design Category D) AND wind loads (basic wind speeds of 195 mph or more and Exposure Category C). Projects must be approximately $5M or more in construction dollar value.

The 195mph basic wind speed requirement is typically used for DoD projects on Guam, but civilian projects are usually designed for 170mph. Small Business contractors may have difficulty meeting this requirement. Other NAVFAC solicitations for similar construction projects on Guam do not have this requirement. Request that the requirement be relaxed to 170 mph basic wind speed or waived.

RESP: For Factor 1 Experience, RELEVANT CONSTRUCTION PROJECT wind loads will be revised to (basic wind speeds of 170 mph or more). See forthcoming amendment.
