# Question Govt. Response

For Volume 1, Factor 1 – Experience, Subfactor 1A – Project

Experience, the following is stated with regard to the number of projects offerors are responsible to submit

“Submit the attached "Project Experience" form addressing specific experience elements below for up to 3 relevant projects completed in the last 15 years” (RFP p.46). In the

Key Trades paragraph, this is countered by asking for “The offeror shall submit a maximum of three (3) exhibit projects

(Samples of Work) produced within the last five (5) years”

(RFP p.46). Please clarify if this key trades paragraph should be last 15 years to match the preceding paragraph and/or if the key trades paragraph is an optional requirement for submission.

The language in the solicitation is correct, the Key Trades requirement is from the last 5 years, not 15 years. Also, the Key

Trades submission is not optional.

For Volume 1, the following is said for the organization and submission, “Include folders and files for electronic formats named as follows:” (RFP p.46). Please clarify if these factors are to be separate documents or be incorporated into a larger Volume 1 document. In other words, would the National Parks Service prefer 1 PDF with each Factor tabbed/bookmarked or does the NPS desire each Factor to be submitted as a separate PDF file in a

Volume 1 zipped folder?

The Volume 1 submission should just be one PDF file, and the

Volume 2 submission should be one PDF file.

Note #12 on planSP1.1 The plans mention that in some cases to run piping perpendicular to the thru floor joists.

This cannot be accomplished.

Design Team disagrees. Please refer to the entire keynote #12 on

Can some soffits be added for some of the piping that is to run perpendicular to the joists?

No soffits are permitted unless specifically called out and detailed in the contract documents.

Plans show risers from floor to floor in the wall. Will the wall be insulated so the wet pipe riser does not freeze in cold weather?

There is no wet sprinkler piping shown within any of the exterior walls.

Do we provide any safety factor in our hydraulic calculations?

Yes, refer to specification sections 211313 1.5.E.1 and 211316

1.5.E.1 for the required sprinkley system safety factor

Will we be able to submit change orders for escalating material costs through the duration of the project?

No, this contract will be awarded as a firm fixed price contract.

Regarding Security and Video Surveillance Systems - Can the requirement for a BICSI / RRDD certification be waived and or can this service be subcontracted? Also, can the requirement for Cisco CCNP certified engineer be waived and or can this service be subcontracted?

Certification requirements cannot be waived, but the services can be subcontracted to an owner approved subcontractor

Would the National Parks Service accept natural gas substitutions for the heat pump VRF system to allow for reduced electrical load and higher efficiency?

No. Construction shall follow drawings and specs.

Backboards?

While plywood backboards are specified under Division 27 and are indicated on sheets E1.1 and E6.3, it is not the intent of the Contract

I am with xxxxxxxxxxx, we were the exhibit design sub consultant to GWWO on this project. We were wondering if we were able to join a fabrication team as a sub consultant for the media programming or if we are excluded since we were the original exhibit designers?

Unfortunately, no firms that were part of the design work will be able to be a subcontractor for the construction effort.

Can you clarify what metal roof areas, if any, are being replaced. The drawings indicate coating the metal roofs in a few different area's as per note 7.4.
