QUESTION ANSWER

1. In light of the current health concerns related to the Coronavirus

(COVID-19) pandemic, and in order for the contractor to maximize the time available to provide the Government with the best possible value, will the Government please allow electronic proposal submission versus hand-carried bids?

No, the Government does not intend to accept electronic proposals at this time.

2. In a quick review of the plans for this project, there is a string of architectural and structural plan sheets missing from the solicitation. See attached marked up index sheet. Please advise.

Please reference Amendment 0001 to the solicitation. This amendment removed all existing drawings and specifications (dated 13 April 2020) and replaced them with revised drawings and specifications (dated 19 May 2020).

3. Could you turn on the IVL for us Subcontractors please.

The Interested Vendors List (IVL) is active; however, you must be logged into the beta.sam.gov website to view it. If you are logged into https://beta.sam.gov and cannot see the IVL, you will need to contact the

Federal Service Desk for assistance.

4. I was hoping that you could direct me to a resource that has the list of

General Contractors who are bidding this project. I am currently working on a bid for the landscaping and would like to submit our proposal to all GC who are bidding.

5. Can I get a list of contractors bidding this job so I can bid sub work?

6. I’m reaching out on the Fuel Systems project in Mountain View. We provide testing and inspection services and would like to team with the contractors that usually include our scope in their bid.

Questions and Answers

Effective 12 August 2020

QUESTION ANSWER

10. Will the National Guard be issuing an RFP for the Special Inspections on the Fuel Systems Aircraft Corrosion Control Hanger in Santa Clara? If so, where would we be able to access plans for this project? Sam.gov?

No, the Government does not intend to issue a separate RFP for Special

Inspections for this project.

11. Will the site visit attendees be allowed to take photos with their cell phones or personal cameras during the Site Visit on August 11, 2020?

Yes; however, you will not be permitted to take pictures of aircraft or of military personnel.

12. Due to the fact that the Plans and Specifications for this project were replaced effective 2 AUG 2020 with Amendment 0001, we respectfully request that the due date for this bid be extended by two weeks. This will help us ensure that our teams have ample time to review the new documents and confirm that our subcontractors have the information they need to provide us with the best possible proposals.

The Government does not intend to extend the solicitation deadline at this time. The plans and specifications issued with the solicitation were “Issued

For Bid” and therefore represent a 95% design. The plans and specifications issued in Amendment 0001 were “Issued For Construction” and represent a completed, 100% design. In comparing the differences between the different plans and specs, the Government believes that the changes are superficial in nature and do not merit an extension of the solicitation deadline.

13. Under Clauses Incorporated By Full Text, on page 42 of 141, referencing

FAR clause 52.236-1 Performance Of Work By The Contractor, will the

Government consider the Contractor’s general conditions as part of this self-perform requirement value?

The language of the FAR Clause indicates that, “The Contractor shall perform on the site and with its own organization, work equivalent to 15% of the total amount of work to be performed under the contract” (emphasis added).

General Conditions may be considered; however, it is incumbent upon the

Contractor to demonstrate that General Conditions being considered are measured based on the effort (versus cost/price), are being performed onsite, and are being performed by employees of the prime contractor.

14. Drawing 05-A601 shows the different finishes for the different rooms but lists no manufacturer, color, item, etc. for the various finish types i.e.

CPT-1, CPT-2, VCT-5, etc. Please provide specific finish materials.

Sheet 05-A601, Finish Schedule Legend has note to refer to specification section 09 06 00 for colors of materials as well as general note 3. This specification section has the information being requested including the colors/brands/types of materials.

Questions and Answers

Effective 12 August 2020

QUESTION ANSWER

15. Specifications state that the Fabricator and Erector must be AISC

Certified. Can this be waived. Please advise if this certification can be waived.

No, AISC (American Institute of Steel Construction) will not be waived and is required. Due to the complexity of this project and amount of steel, the engineer of record recommends keeping the standard UFGS (Unified Facilities

Guide Specifications) language in place. Further, the UFGS specification provides guidance to the specification writer/designer of record with the following note: “NOTE: AISC has a certification program in effect that confirms that a certified structural steel fabricating facility has the personnel, organization, experience, procedures, knowledge, equipment, capability, and commitment to produce fabricated steel of the required quality for a given category of structural steel framing. Consider deleting this paragraph if there is a minimal amount of steel on the job”. This project does not fit that category for “minimal amount of steel”.

16. Specification section 316613 part 2.1.1 states that the subsurface information is presented in the geotechnical report. Please provide the geotechnical report.

Please reference Amendment 0002 which incorporated the Geotechnical

Report.

17. Will the Owner provide the tax-exempt certificates required? If not, all general contractors and subcontractors will need to include 9% sales tax on all material to be used on the project.

Yes, the Government will provide required tax exemption certificates.

18. Please confirm that small business goals stated in the RFP reflect base bid participation percentages and exclude bid options.

This is incorrect. The small business goals are stated for the entire project, including the base and all additive bid items.

19. Has the Owner's budget included the cost of 9% sales tax on all material to be used on the project?

Yes, the Government’s estimates included sales tax.

20. Ref. 7, 9 & 11/05-S503; these details are drawn for 2L5x3x3/8 bracing connections as called-out on 05-S115. What is the detail at the WT7x19 bracing connections as called-out on 05-S118?

The Government is still pursuing an answer to this question and will provide an updated document later. HDR anticipates releasing the updated documents in by the end of the week.

21. Ref. 05-S114; How do the W12 beams attach to the CMU walls? Please see sheet 05-S510 and details 3 and 7 for W12 to CMU wall connection.

22. Ref. 05-S119 thru 05-S122; Please provide field splice locations and details for the W14x48 truss chords at Grid Lines HE & HF between

Grid Lines H3 and H11.

The Government is still pursuing an answer to this question and will provide an updated document later. HDR anticipates releasing the updated documents in by the end of the week.

Questions and Answers

Effective 12 August 2020

QUESTION ANSWER

23. Ref. 1 & 4/05-S502; At the 21 locations where truss bottom chords have both horizontal and vertical gusset plates, we assume the W12x40 lower chord frame beam connections may be brought out from the truss cords similar to details on 00-S517. Otherwise, the W12 frame beams cannot be erected. Please confirm this is acceptable.

Yes, this is acceptable as long as the alternate details on sheet 00-S517 are satisfied as minimum.

Spec:

Question: In response to Amendment 0001, dated 02 Aug 2020, we are missing Sheet 05-C904, Wash Rack Trench Drain Details, from Volume

2 of the Project Drawings. Please provide.

Sheet 05-C904 was unintentionally included on the Sheet Index and does not apply. Please disregard references to this sheet; a revised sheet index will be provided in a conformed set of drawings upon contract award.

25. Discipline: Architectural

Sheet:

Spec: 09 90 00 Paints and Coatings

Question: Subpart 1.4.2 of Section 09 90 00 Paints and Coatings states

“All Contractors and Subcontractors that perform surface preparation or coating application shall be certified by the Society of Protective

Coatings (SSPC) to the requirements of SSPC QP 1…” Per the SSPC website, QP 1 certification is primarily meant to attest to the ability to apply coatings in a marine environment such as bridges, off-shore drilling, ships, wastewater treatment facilities, and power generation facilities. This requirement will prohibit the local experienced painting contractors from being able to perform the work and will result in a substantial increase in the cost of this work, which will be reflected in the prime contractors’ bids submitted to the Government. SSPC QP1 certified painters typically do not perform painting work for buildings and other architectural surfaces. We request removal of the requirement for the use of only SSPC QP1 certified painters on this project.

UFC 1-200-01 paragraph 4-1.3 corrosive category applies to the interior of hangars (additionally applies to this hangar due to proximity to San Francisco

Bay). Spec Section 09 90 00 par 1.4.2 will not be waived.

26. Discipline: Contracting & Structural

Sheet:

Spec: 01 45 00.00 00 Quality Control, 03 30 00 Cast-In-Place Concrete

Question: Please confirm the experience requirements for the CQC

Systems Manager per 01 45 00.00 00, paragraph 3.4.2 and the CQC

Personnel, Structural meeting the requirements 01 45 00.00 00, paragraph 3.4.3 meet the requirements for cast-in-place concrete operations. Are we correct that the statement in Section 03 30 00, paragraph 1.6.7, “Quality control personnel must be employed by the

Contractor” and subsequent sub-paragraph 1.6.7.1, Quality Manager

Qualifications as a licensed professional engineer is in included in error?

The question’s assumption for requirements in specification 03 30 00 paragraphs 1.6.7 and 1.6.7.1 is not correct. Requirements in referenced specification sections of 03 30 00 is intended.

27. Discipline: Architectural

Sheet:

Spec: 07 81 00 Spray Applied Fireproofing

Question: Upon review of the drawings, we find no mention of fireproofing and / or intumescent painting to clarify what is required.

The specifications refer to spray-applied fireproofing and intumescent paint without differentiating the location for each system. The specification states that the roof deck is protected only where indicated, and there is no indication. Please clarify and/or confirm that

Specification Section 07 81 00, Spray-Applied Fireproofing does not apply to this project.

Sheets 05-G106, 05-G107, 05-G108, and 05-G109 indicate various locations requiring fire separations. Spray applied fireproofing may be utilized as part of those separation assemblies. Specification 07 81 00 is applicable for the project.

QUESTION ANSWER

28. Discipline: Architectural

Sheet:

Spec: Section 07 61 14.00 20 Steel Standing Seam Roofing

Question: The reflected ceiling plan drawings, as well as various details and sections throughout the drawings, indicate that insulated metal panel soffit systems are to be provided in certain areas. However, Subpart 2.6

Soffit Panels of Section 07 61 14.00 20 Steel Standing Seam Roofing states that the soffit panels are to be “. . . of the same material as roof panels, and formed or patterned to prevent waviness and distortion.” The roof panel material specified within the referenced section of the specifications is a non-insulated, single-skin standing seam metal roof panel. Since a conflict exists between the specifications and the drawings, please confirm our interpretation that the soffit panels are to be a non-insulated, single-skin metal panel of the same material as the roof panels as set forth within the specifications.

Sheet 05A-A112 (Roof Plan) and 05-A200, 05-A201, and 05-A202 (Exterior

Elevations) include the curved roof surface areas. Section 07 61 14.00.20 applies to the curved roof areas of the building. Section 07 41 63 Fabricated

Roof Panel Assemblies applies to non-curved (sloped) roof areas.

29. Discipline: Fall Protection

Sheet: 05-A106, 05-A109, 05-A110, 05-S124

Question: Sheet Number 05-A106 includes a note that states, “Centerline of beam for mounting safety trolly (sic) for fall protection.” Key Note 77 on Sheet Numbers 05-A109 and 05-A110 both also state, “Steel Beam for Fall Protection Trolly (sic) Mounting – See Structural”. Sheet

Number 05-S124 includes a note that states, “Fall protection W8 beams are supported at the bottom of W14X80 beams,” as well as another notes that states, “Verify the final location of the fall protection beam with the

Contracting Officer.” The RFP is clear that the Contractor is to provide the W8 fall protection beams; however, the RFP contains no requirements for the Contractor to furnish and install any fall protection systems for these beams. Please confirm our interpretation that the

Government will be furnishing and installing the fall protection systems.

The Government will be furnishing and installing fall protection system(s).

Contractor shall coordinate, provide and install installation of structural supporting elements indicated on drawings.
