QUESTIONS AND ANSWERS

JUNE 29, 2020

Question 10: Specification 00 0102 Project information states Hazardous material removal is in our scope. However it does not elaborate on what the material is nor does it quantify the material. Could you please lets us know what this material is and approximately how much so we can properly quote?

Answer 10: FAA is performing the Asbestos remediation under another contract.

Lead-Based Paint removal/remediation is required to be performed by the contractor, and is addressed on drawing G-002, General Note 4. FAA has provided to LWPB prior surveys/reports documenting locations that Lead-Based paint occurs or is suspected in several locations throughout the building. However, FAA had previously directed us to NOT include the surveys/reports in the Contract Documents, or a spec for lead remediation procedures, which would better define the GC’s scope for this task.

Drawing AD100, Demo General Note 6, instructs the contractor to treat any PCB ballasts discovered, as hazardous waste. Presence of such ballasts is unknown.

We are not aware of any other hazardous materials in the building.

Question 11: In chapter 33 construction safety, there is a reference made to follow OSHA regulations and MMAC policy (33-2). Can you please inform us as to the MMAC safety policy for construction projects?

Answer 11: The Reference is to FAA AC Order 3900.21, Chapter 33, Section 2, which states that “all” personnel including construction contractors must adhere to the Construction Safety requirements in Chapter 33 of the order. Please see attached FAA AC Order 3900.21, Chapter 33 and referenced FAA AC Order 3900.19 Chapters 13 and 17.

Question 12: The mechanical and electrical sub-contractors are required to submit past performance surveys (or questionnaires). To whom do they submit them? Our discussion at the site lead me to believe that the General Contractors would submit ONE electrical PPS and ONE Mechanical PPS with our bid package. Please confirm.

Answer 12: The FAA envisions that the general contractor will decide who will be their mechanical and electrical subcontractor prior to submitting their proposal in response to this SIR. Provision L.3 of the SIR entitled Instructions for Preparation and Submission of Proposals, paragraph (f), Section II – Past Performance Information, states that the Offeror, along with their Mechanical and Electrical subcontractors, will send PPS to clients who are familiar with the work demonstrated through previous contracts of a similar nature. This paragraph also states that Offerors shall request a minimum of two (2) with a maximum of four (4) Past Performance Surveys as a general contractor as well as a minimum of two (2) with a maximum of four (4) Past Performance Surveys for their mechanical subcontractor and a minimum of two (2) with a maximum of four (4) Past Performance Surveys for their electrical subcontractor. All completed PPS’s shall be submitted directly to the contracting officer at cynthia.cooper@faa.gov.

Question 13: Referencing the term mechanical contractor: Do BOTH the plumbing and HVAC sub-contractors need to submit a past performance survey or only the

HVAC?

Answer 13: If the general contractor has selected a subcontractor that will be performing the plumbing portion of the contract and a separate subcontractor performing the HVAC portion of the contract, then PPS’s will be required for both subcontractors.

Question 14: The HVAC Duct Specification 230713 only list the outside air ducts and mixed air plenums to received insulation, what is the intent for the supply, return air & exhaust?

Answer 14: Please see attached PDFs of Additional Schedules for HVAC Duct and Piping Insulation.

Question 15: The HVAC Equip. 230716 & HVAC Piping 230719 list the equipment and piping systems but no schedule of materials or thicknesses, can this information be provided prior to bid?

Answer 15: Please see response to Question 14.

Question 16: Mechanical and Electrical Subcontractors are requesting a site visit to look at the basement area of the building. We understand that this area is still being abated and that access to this area was unavailable during the initial walkthrough. We request an additional walkthrough to this area and additional time of 2.5 weeks following the additional site visit in order for the mechanical/ electrical subcontractors to process the site visit information and complete their estimates.

Answer 16: Mechanical Site Visit was held on July 14, 2020. Unfortunately, the FAA’s schedule does not allow for an extension of 2.5 weeks.

Question 17: Page number G002 references that the general contractor is responsible for lead abatement. Can you provide an environmental report as to the locations of the lead contaminated areas?

Answer 17: Please see response to Question 10.

Question 18: The HVAC Duct Specification 230713 only list the outside air ducts and mixed air plenums to received insulation, what is the intent for the supply, return air & exhaust?

Answer 18: Please see response to Question 14.

Question 19: The HVAC Equip. 230716 & HVAC Piping 230719 list the equipment and piping systems but no schedule of materials or thicknesses, can this information be provided prior to bid?

Answer 19: Please see response to Question 14.

Question 20: Page PD 121 has a note (remove storm drain piping in hatched area) however there is no roof drain piping shown. Please advise.

Answer 20: The mechanical engineer was not able to verify exact locations and exact routing of existing storm drainage piping in this area. Field verification will be required by subcontractors for quantities and extent of piping to be demolished.

Question 21: What is the depth of the drilled piers shown the Detail 1/S-102?

Answer 21: Based on the geotech report, bidders should assume the bearing stratum is 19’-0” below finish floor.

Question 22: The bidding notes on sheet AD100 call for us to palletize and deliver carpet to building 50. Can you please identify where building 50 is, presuming it is on campus.

Answer 22: Building 50 is on campus, please see attached map showing project site in relation to building 50, we ask that the contractor coordinate a time to meet with the FAA inspector at Building 50 to gain access into the building. The contractor needs to keep the carpet tiles clean and dry. Palletize and shrink wrap removed carpet in order for carpet to be recycled. Do not leave carpet tiles outside at any time during removal or delivery.

Question 23: Sheet AD213 shows equipment X02 to be moved and stored and reinstalled (demo note Q06). What is equipment X02? (presume a copier)

Answer 23: X02 is an ice maker and X04 is a refrigerator.

Question 24: Regarding low voltage systems conduit

a. Will all systems be required complete pipe back to control source/closet?

Or

b. Can a cable tray be used in corridors back to closets and low voltage stub ups be routed to the tray?

c. If tray is acceptable can the systems cabling be installed on same tray system?

Answer 24: Yes, option A: all systems are required to complete pipe back to control source/closet.

Question 25: In the working hour clause F.1 it clearly indicates that all demo work is to be afterhours 6 pm to 6 am. I want to inquire if this is a correct clause so I can communicate that to our bidding subcontractors. My understanding is the building will be occupied in portions, but not necessary in the areas we are working and the building will not be fully occupied. Can the demo take place during normal working hours?

Answer 25: Typically, if the buildings are occupied, demolition is conducted afterhours to minimize the impact to the occupants; however, since the only occupants in the building work 24/7, there is no benefit for having the demolition after hours. Demolition can be performed during normal working hours.

Question 26: When the structural criteria for the job is entered on the ISAT website for seismic design it says there is no seismic bracing required. Is Seismic bracing required for this job? If so, please provide required seismic criteria for seismic bracing design.

Answer 26: Confirmed with Structural Engineer, project site is seismic design Category B, therefore seismic bracing is not required. Only vibration isolation.

Question 27: Doors C116B and C116C on the door schedule are referred to as being elevation 16. Elevation 16 is not shown on the drawings. Please provide clarification.

Answer 27: Door C116B, frame 16 is correct and a frame elevation will be added to the drawings by a future Amendment. Door C116C should be frame 16 OPP.

Question 28: Unit prices identified in 01 2700 are not listed on the bid form. Are the unit prices required to be submitted with our bid? If yes, please provide a revised bid form.

Answer 28: Revised Attachment 1, Section B – Supplies and Services will be added to SIR Amendment 0003.

Question 29: Drawing S-100 calls for unit pricing for drilled pier casings per lf and per pier. Is this unit pricing to be provided? If so, please add to the list of unit prices.

Answer 29: Revised Attachment 1, Section B – Supplies and Services will be added to SIR Amendment 0003.

Question 30: The solicitation F.3 Work by others, states that asbestos containing materials will be removed by others. Drawing G-002 Demo General Note 5 states that there is also lead-based paint to be mitigated/removed by the general contractor. Is the lead-based paint mitigation/removal by others as well? If not, what are the extents of the lead-based paint that needs to be mitigated/removed? Is there a test report defining the extent of this work? If so, please provide.

Answer 30: Please see response to Question 10.

Question 31: The solicitation F.3 Work by others, states that asbestos abatement must be accommodated by the general contractor in the construction schedule. It is our understanding that the asbestos abatement is currently taking place. Will the abatement be complete prior to the start of construction? If not, please provide the anticipated durations, by phase, that need to be accommodated in the construction schedule.

Answer 31:

Pre-construction: Asbestos abatement is currently in progress and will be complete in areas that are accessible prior to the start of construction.

Phase 1A: Contractor will demo this area.

Phase 1A Asbestos abatement: will take place in Phase 1A after demo opens up access to new areas that require abatement, 3 weeks required for abatement.

Phase 1A: Contractor will renovate this area.

Phase 1B: Contractor will demo this area.

Phase 1B Asbestos abatement: will take place in Phase 1B after demo opens up access to new areas that require abatement, 3 weeks required for abatement.

Phase 1B: Contractor will renovate this area.

60 days required between completion of Phase 1 and start of Phase 2: Per the specifications, Phase #2 work at the site shall not start until 60 days minimum after the Owner’s acceptance of, and the AHJ’s issuance of a Certificate of Occupancy for, Phase #1 work, to allow time for relocation of people & furniture (by others), and to allow time for asbestos remediation (by others).

Phase 2: Contractor will demo this area.

Phase 2 Asbestos abatement: will take place in Phase 2 after demo opens up access to new areas that require abatement, 6 weeks required for abatement.

Phase 2: Contractor will renovate this area.

Question 32: Please confirm that the standard warranty on the project is one year.

Answer 32: Refer to Clause 3.10.1-20 for construction warranties.

Question 33: During the site visit, there were some areas that were inaccessible. Will an additional site visit be available? If so, will subcontractors be permitted to attend?

Answer 33: Mechanical Room Site Visit was held on July 14, 2020.

Question 34: With the possibility of another site visit, will the proposal due date be extended?

Answer 34: The proposal due date is extended to July 22, 2020 in Amendment 0003.

Question 35: Section 01 10 00, Paragraph 1.03, Item C, Phase #1 Completion of Work states the period of performance for this work 820 calendar days. Item D, Phase #2, states this work cannot start for 60 days after Phase #1 is complete. However, a period of performance is not provided. Please provide POP for Phase #2.

Answer 35: 820 calendar days is for the complete project all phases included. The 60 days is for the time in between Phase 1 and Phase 2.

Question 36: The Plumbing Spec seems to have enough of the information needed, but the HVAC Duct (230713) only lists the Outside Air Ducts and Mixed Air Plenums to receive insulation, what will the S/A and R/A require? The HVAC Equip. (23016) and HVAC Pipe (230719) lists all of the Equip. & Pipe Systems but no schedule of materials or thicknesses. There appears to be quite a bit of exposed areas on this project as well and that is not addressed in any of the spec. sections. Will the exposed ducts receive external insulation, will they be lined or is no insulation required?

Answer 36: Please see response to Question 14.

Question 37: Can proposals in response to this SIR be submitted in person?

Answer 37: Potential offerors need to keep in mind that access to the Mike Monroney Aeronautical Center has been reduced due to COVID-19 restrictions. Potential offerors also need to keep in mind that contracting personnel from AAQ have been working remotely for several months due to COVID-19 restrictions and will continue to work remotely for some time to come. Because of these situations, SIR Provision L.3

INSTRUCTIONS FOR PREPARATION AND SUBMISSION OF PROPOSALS,

paragraph (b) was specifically designed to say “Documentation shall be submitted electronically in accordance with Section L, Provision 3.2.2.3-20. Clause 3.2.2.3-20 OFFERS (JAN 2018), paragraph (a) says “The offeror (you) must submit responses to this SIR by the following electronic means pdf version provided via email”.

Potential offerors are advised that failure to comply with these constructions may result in your proposal not being considered. Potential offerors are further advised that there are size restrictions on attachments to emails that may be submitted in response to this SIR and are cautioned to not wait until the very last minute to submit proposals. AMS

Clause 3.2.2.3-14 Late Submissions, Modifications and Withdrawals of Submittals is included in Section L of this SIR and will apply to any late proposals received.

Question 38: Would the FAA consider material substitutions?

Answer 38: Specification 01 6000 specification included in the SIR provided makes no provision for reviewing substitutions prior to receipt of proposals. Within 10 days after contract award, the successful offeror may submit substitution requests that may or may not be approved; therefore potential offerors are requested to provide their proposal based upon the current SIR requirements. The future successful contractor is put on notice that the responsibility to provide all the necessary data in order to enable the FAA to potentially review product substitutions after contract award rests solely with the future successful contractor. General requests that do not provide complete data, catalogs without specific proposed products identified, and links to a manufacturer’s site requiring the FAA to find the applicable data ourselves will not be reviewed.

Question 39: Are liquidated damages applicable to this requirement?

Answer: No

Question 40: We have had numerous request for a secondary site visit to tour the entire building. Will it be possible to conduct a second, whole building site visit?

Answer 40: The FAA has already allowed for a site visit for the entire site and a secondary site visit for the mechanical room. All potential contractors have had the opportunity to view the site. No further site visits will be allowed.
