Addition to Paint Blast Booth Bldg Questions and Answers 28 August 2020

Q25: Is this project for an internal blast or an external blast? The floor plan on one of the attachments shows a blast chamber and a blast cabinet, which make me think this is an internal blast situation. Also, the hazard rating indicates that potentially explosive materials are stored inside the building.

A: The building is rated Storage Group S-1 resulting in no blast rating for any doors.

Q26: If this is an internal blast, should door 108C also be blast resistant to provide protection to the corridor and restrooms?

A: Doors are not blast rated.

Q27: What's the blast load(s) for this project? If this is an internal blast situation, is there a study available where pressures have been calculated based on multiple reflecting surfaces?

A: The building is rated Storage Group S-1 resulting in no blast rating.

Q28: Is there a damage category these doors need to meet? If not, can a description be provided on how much damage are the doors allowed to have? The class 2/division 2 rating seems to only describe the type of hazard

(ie. explosive materials) within the building, but I couldn't find any guidance on how that translates to the response of the doors.

A: Doors are not blast rated.

Q29: The new Q&A spoke about blast rated light fixtures, etc, but we wanted to make sure were all on the same page regarding the Doors. Neither the plans nor the specs show any blast rating for the openings - just wanted to make sure that was the intent.

A: Doors are not blast rated.

Addition to Paint Blast Booth Bldg Questions and Answers 24 August 2020

1. Is this project sales tax exempt? If the project is sales tax exempt can the government provide a sales tax exemption certificate?

A) This project is not sales tax exempt.

2. Where will the designated parking area be for workers accessing the construction site?

A) Designated parking area will be determined at pre-con meeting with winning contractor.

3. Will the government accept the use of the industry leading Procore Project Management software as the primary submittal and data tracking tool for this project?

A) The government will not accept Procore Project Management. Any large files can be uploaded to DOD

FA301020R00350002

SAFE.

4. Does the Government have a fire alarm servicer that they currently work with? What is the name and contact information of the person or persons that will need to be coordinated with for security and fire alarm and suppression systems work and/or disruptions?

A) Name and contacts will be given after award.

5. Due to current potentially significant tariffs being placed on the importation of building materials such as wood or steel by the current Presidential Executive Branch, if a tariff is placed after bid time and before award will the government consider a price escalation on a contract value for products such as steel or wood should the executive branch levee tariffs effecting such materials? Most of these materials would still have been Buy American compliant as the tariffs would increase pricing on all steel or wood materials, regardless of origin.

A) No, the government will not consider a price escalation. Per the provision 52.216-1 in the solicitation, the government contemplates a firm-fixed-price contract award. Firm-fixed-price contracts are not subject to any adjustment on the basis of the contractor's cost experience in performing the contract.
