QUESTIONS AND ANSWERS

NASA Ames Research Center Solicitation No. NNA16543413R

Answers to Questions

This document contains Questions and Answers for questions received through July 25, 2016.

Please note that not all questions received through July 25, 2016 have been addressed in this document. Answers to questions received will be released in subsequent amendments as they are made available.

1. Question: Can requirement be set up in a manner where contractors are down selected based on qualifications? Given the large amount of interested GCs, and the extremely healthy construction market, we highly recommend that there be a two-step process whereby GCs respond to a Request for Qualifications (RFQ) first. Then a Request for

Proposal (RFP) step for pricing allows for only the top 3 - 5 firms that score the highest on the RFQ step to be invitees for the RFP step. That way there are not a lot of firms wasting their time and resources on the pricing step. This would allow companies to weigh in if they want to move forward and submit a proposal for the requirement.

Answer: The acquisition strategy for this procurement was developed as a result of extensive research, including industry input received in response to Requests for

Information (RFI). The Government’s goal for this procurement is to promote competition while considering current market conditions to obtain best value. The two-step process described above reduces the Government’s flexibility to maximize tradeoffs among the evaluation criteria identified in the RFP.

2. Question: Are special FAA permits required for cranes due to proximity to airfield?

Answer: The Contractor shall notify the FAA if construction equipment exceeding the height of the surrounding buildings is to be used on the project site. If notification is required, the Contractor shall submit a completed FAA Form 7460-1, Notice of Proposed

Construction or Alteration, to the FAA Southwest Regional Office at least 45 days prior to the start of construction. FAA Form 7460 is available on-line at https://oeaaa.faa.gov/ .

3. Question: Is additional storage area available?

Answer: Yes, a supplemental storage may be coordinated with the Government.

Requirements are outlined in Section J, Attachment J.1, entitled “Specification No.

https://oeaaa.faa.gov/

K14020,” specification section 01 50 00 TEMPORARY CONSTRUCTION FACILITIES AND

CONTROLS.

4. Question: Is there a recent soil HAZMAT Report?

Answer: There is no recent hazardous materials test report for existing on-site soils. There is no known soil contamination on the project site. If pre-existing contamination is discovered during construction, NASA will assume responsibility for disposal. See Section J, Attachment J.1, entitled “Specification No. K14020,” specification section 01 35 40.00 20 ENVIRONMENTAL MANAGEMENT.

5. Question: Will the volleyball courts be removed prior to construction?

Answer: The Contractor will be responsible for removal of the volleyball courts. See

Drawing C011.

6. Question: Will the existing trees located on the construction site be removed?

Answer: The Contractor is responsible for site-specific tree removal per Drawing C011.

7. Question: Is there a designated area for contractor parking?

Answer: Yes, there is a single designated contractor storage, parking, and staging area located northeast of the project site. See Drawing G009.

8. Question: Are there underground ducts that need to be removed?

Answer: Yes, the scope of underground demolition is shown on Drawing C012.

9. Question: Can the road east of the construction site be closed?

Answer: The referenced road, C-Lane, must remain open during construction; however, it may be closed temporarily for construction operations. See the traffic control requirements outlined in Section J, Attachment J.1, entitled “Specification No. K14020,” specification section 01 50 00 TEMPORARY CONSTRUCTION FACILITIES AND CONTROLS.

10. Question: Page L-7, Item (6) reads “One (1) electronic copy of the cover letter and each volume shall be submitted (in addition to the hard copies specified in (b)(1) above) in PDF

(Portable Document Format). The electronic format data shall be provided on quality, virus-free CD-R/CD-RW with an external label indicating: (1) the name of the Offeror, (2) the RFP number, and (3) a list of the files contained on the CD. In the event of any inconsistency between data provided on electronic media and proposal hard copies, the original hard copy data will be considered the intended data”. Is it possible to offer a flash drive as an alternative electronic submittal. The file name can include the name of the project and solicitation number.

Answer: Unfortunately, NASA policy precludes utilizing removable media devices, such as flash drives, for transferring data to Government-owned systems.

11. Question: On page L-9, Information Provided by Offerors, 2nd paragraph “Offerors shall provide a Past Performance Information Summary identifying a maximum of five (5) recent and relevant contracts that it has performed as a prime contractor for projects similar in size ($20M - $50M)….” Comment: Suggest lowering the threshold to $13M, we have a relevant project for consideration but does not meet the current cost range as stated in the draft RFP.

Answer: The Government will consider modifying the project size threshold in L.14

PROPOSAL PREPARATION—SPECIFIC INSTRUCTIONS, Volume 1 PAST PERFORMANCE, Paragraph (A) Information Provided by Offerors, to remove the $50M upper limit and allow Offerors to provide past performance information for contracts of lesser value if the Offeror does not have enough relevant contracts that meet the value requirement.

12. Question: Item #3 reads: “ Each Offeror is responsible for assuring that the customers return questionnaires directly to the Government 10 days prior to the proposal date.” Comment: Suggest that these are provided up until the proposal due date. We’d like to allow Owner’s as much time as possible to complete NASA’s extensive (4) page

Past Performance Questionnaire and not limit them with shorter time frames to respond. It’s to NASA’s advantage to welcome the opportunity for all to use the time needed to complete NASA’s document requirements for a best value evaluation process.

Answer: The receipt requirement for past performance questionnaires is standard across

NASA ARC procurements. The Government feels that there is sufficient time for Offerors’ clients to complete and submit the questionnaires. The receipt requirement remains unchanged.

13. Question: Provision L.11, PROPOSAL PREPARATION—GENERAL INSTRUCTIONS, indicate the due date for Volume I is July 8, 2016. However, Volume I includes several items that require pricing data, such as the SF1442 and Small Business Utilization, and the Price

Proposal (Volume III) is not due until August 5, 2016. Is this a typo?

Answer: Amendment 2 revises the due date for Volume I to August 5, 2016.

14. Question: Are sign-in sheets from the Site Visit going to be available on the FedBizOpps website?

Answer: Yes, sign-in sheets and all materials from the Site Visit are posted with

Amendment 3.

15. Question: Has a geo technical report been provided?

Answer: NASA intends to post the geotechnical report for this project in the near future.

16. Question: Is there a known water table?

Answer: On June 29, 2016, the water table elevation in the monitoring well at the northwest corner of the site was approximately elevation 8.1 feet, based on the project vertical datum. The water table elevation varies over time; therefore the water table elevation during construction will likely be different.

17. Question: Fire Protection: What size water main is in the street? Type of pipe?

Expected water pressure? How do we shut down water for tie-in?

Answer: Per detail 1/C504, the existing water main is 8-inch diameter, and is identified as asbestos cement pipe (material to be verified by the Contractor). The water pressure is approximately 65 to 70 psi. There are valves on the water main upstream and downstream of the new point of connection. The procedure for a utility shutdown is outlined in specification section 01 14 00, WORK RESTRICTIONS.

18. Question: Low Voltage: Plans call for CAT6 network cabling. However, the specifications call for CAT6A. Please confirm which type of network cabling shall be installed.

Answer: Network cabling shall be Category 6A, in accordance with the requirements of specification section 27 10 00.

19. Question: The Basket Tray is shown for low voltage cable pathways. Please confirm if this is in Electrical or Low Voltage scope.

Answer: The contract documents define the entire project scope of work. It is left to the discretion of the Contractor to determine how the work scope is divided among subcontractors. The low voltage cable pathways shown in the TC (telecommunications) and EAV (audiovisual) drawings may be provided and installed by any qualified subcontractor.

46. Question: On Door Detail sheet ES501, Detail 5 for Mullion Mount Card Reader Single

Door, calls out for an Electrified Mortise Lock. Now on all the ES drawings (ES111, ES112, ES121, ES122) the access control door bares no reference to which Door Detail, aside mailto:Robin.L.Wong@nasa.gov from being Mullion Mount. I had to use the Door Number to reference back to the Door

Schedule/Detail sheet A704 to see what Type of Door was being installed.

Doors X158, X186, X202, X245, X258, X284 are all spec’d out to be FGA-1 doors (Full

Glass Aluminum Curtainwall), with a 3 ½’ Frame around the glass. An electrified mortise lock will not fit into this width of frame. What would they like us to bid as far as electronic locking hardware?

Also, on the doors that are receiving Crash Bars with Vertical Rods, are those rods

Internal or External? Typically, internal are installed prior to the door being put up. And will they work on a door that has only a 3 ½” frame around the glass?

Answer: On drawing ES501, details 1, 5, and 7 incorrectly refer to a mortise lock.

According to specification section 08 71 00 DOOR HARDWARE, these doors do not have mortise locks. Drawing ES501 will be corrected by amendment. In response to the second question, the specified exit devices will fit door stiles as narrow as 1 3/4".

54. Question: As per 084400, 1.7.1 Protective Covering, “cover finished surfaces of aluminum and stainless steel with protective covering of adhesive paper, waterproof tape, or strippable plastic.” This step adds many hours and much cost to the product out of our shop. 3.6.4 calls for stripping of protection “immediately after installation.” This only adds more field hours with the removal. As there are no mortar or stucco construction types on the project, is this requirement necessary, and can it be removed? Of course, we apply protection to all frames for the shipping process in cardboard interleaves and plastic protection wrap for delivery to the field.

Answer: Specification section 08 44 00, paragraph 1.7.1 Protective Covering, will be deleted by amendment.
