Question

Answer

I am interested in bidding this project and was able to download the documents but I do not see any architectural pages. Do you know if these are available?

There are architectural sheets. I am not sure why this Contractor wasn't able to download them.

The architectural sheets are at the end of Volume 1.

Is an MDE permit required, and, if so, has it been obtained by

NPS?

AE RESPOINSE: NPS is in the process of acquiring all required permits. Plans and calculations were submitted by the A/E to MDE for review on 6/22; as of the date of this email, comments or revisions from MDE on the application have not been received.

We are an 8(a), Woman Owned, Hub Zone business, and we plan to self‐perform a minimum of 30% of the work on this contract. Are we required to prepare a small business participation plan? No. Small Business Participation Plans are only required for Large Businesses.

May we present primary and alternate candidates for the key personnel roles? Please present primary candidates only.

Reference note D05 / A4. Shall we price the plaster removal as containing ACM?

AE RESPONSE: No. The existing plaster above the Bookstore ceiling should be removed, but per the

Hazardous Materials (HazMat) drawings, the plaster material has NOT been identified as containing

ACM. Note D05 should be revised to read “EXISTING PLASTER CEILING (CONCEALED ABOVE

EXISTING ACOUSTIC PANEL CEILING) TO BE REMOVED”.

We would like to confirm that the Safety Manager’s resume(s) should be presented twice (in Subfactor 2B – Safety and in

Subfactor 3B – Key Personnel).

The Safety Manager's resume only needs to be submitted once. List that person in both places and note that the resume is provided.

Factor 4 states that PPIRS evaluation reports can be submitted in lieu of PPQs. Can CPARs (Contractor Performance

Assessment Reporting System reports) also be submitted in lieu of PPQs?

PPIRS is a companion system to CPARS. It receives the completed CPARS report cards, including contractor comments, as well as other statistical reports on smaller‐value contracts.

Completed/Final reports from either the CPARS system or PPIRS system will be considered. Draft reports may carry less weight. Past Performance information for projects submitted as examples of

Past Experience is requested.

We are finding it difficult to get in contact with Contracting

Officers for PPQs requests due to COVID‐19 closures. Are we able to submit previously completed PPQs?

Yes.

Subfactor 2A – Management Approach is limited to 4 pages. Do the 4 pages include Quality Control, Organization Chart and

Description, Business Practices Unique to this Project and

Location, and Subfactor 2B – Safety?

The 4 page limit applies to the Management Approach only. In this narrative please address Quality

Control, Organization Chart and Description, and Business Practices Unique to this Project and

Location. Subfactor 2B ‐ Safety should be addressed as a separate subfactor. There is no page limit listed for Subfactor 2B use your judgment.

Subfactor 2A states that the information in the section should be narrative format. Should the organizational chart in this section also be in narrative format or is a diagram acceptable? NPS RESPONSE: An organizational chart is acceptible however we do want to see the qualifications of key personnel

Can the 4 pages for the Management Approach and the 6 pages for the Technical Approach be double‐sided? These will be submitted electronically and will be single sided.

Small business requirements – Page 21 of 192 of the solicitation, Special Clause H.4 part (b) states – “The contractor shall ensure a minimum 20% of the total contract value is performed by Small Business.” The first page of the Small

Business Subcontracting Plan states that the goal for Small

Business Concerns is 43%. Please clarify which is correct.

SMALL BUSINESS PARTICIPATION: Small business participation on Page 22, SPECIAL CLAUSE H.4:

Requires a minimum of 20% of the total contract value to be performed by small business. If at any point during the performance of the contract it becomes apparent that the goals will not be met a recovery plan will be requested and if upon contract completion the required % is not obtained it will be appropriately documented in the past performance record. / Separately from Special Clause

H.4, see also Page 58, SMALL BUSINESS SUBCONTRACTING: The goals set in FAR 52.219‐9 are set for all Government agencies. If you are a large business and are requested to submit a subcontracting plan as the apparent successful offeror, the plan should demonstrate the contractor’s proposed subcontracting percentages as they relate to the proposed amount and the small business goals identified in the solicitation. If at any point during the performance of the contract it becomes apparent that the goals will not be met, the appropriate supporting documentation shall be provided to demonstrate the good faith effort. The contractor will not be considered in breach of the contract.

Will the NPS be removing existing furniture and artifacts prior to demolition activities in the existing VC? AE RESPONSE: Other than the entry desk, all exhibits and furniture will be removed. The entry desk is the Contractor's responsibility

Will exhibit drawings be issue prior to bid? There is likely to be coordination work required with the work under this contract. No. Exhibit drawings are still in progress but should be available by sometime in January. The design teams for construction drawings and exhibit design did coordinate the two. As soon as they are available, the exhibit design documents will be provided upon Contracting Officer's approval.

Section 1/A22 shows new elevator footing and pit wall installed underneath the existing stairwell. Please clarify how this is to be accomplished.

AE RESPONSE: The intention is to have the top of the new elevator pit foundation wall become the new support of the existing stair on grade. The elevator pit wall at the southeast face of the pit wall is to step up (from the Exhibit Floor Level to the First Floor level) along the bottom of the existing concrete stair in order to support it. In constructing this, the edge of the stair will be slightly undermined, and the Contractor will need to install sheeting and shoring to prevent soil loss below the stair. The new concrete wall would then be poured with a stepped profile to follow the underside of the slab and any gaps between the top of the concrete wall and the underside of the existing stair slab should be packed tight with blocking or non‐shrink grout. The shelf on which the stair slab will sit will be 4” wide to allow room for the 8” CMU wall to be built on top of the concrete pit wall. Please note that given that this is a stair on grade, this is believed to be the most cost effective approach, however, there is a bit of risk of movement. Should the stair move slightly it could be easily repaired. Alternatively at the Contractor’s option, the edge of the existing stair could be underpinned, which might slightly reduce risk of movement. The work described in this response should be included in the Base Bid.

The bid form identifies item 5 option 4 as systems control allowance. Spec section 012700 definition of contract line items does not include this item 5. Section 012601 par 1.2 allowances does not address item 5. Please identify the allowance amount to be carried in the bid for item 5 option 4.

AE RESPONSE: Provide a price for CLIN Item 5, Option 4 as noted in the in the Contract Price

Schedule. CLIN item 5, Option 4 should be the price for the compatible Controls System to support any combination of the PV array areas noted in Option 1, Option 2, and Option 3, and to provide a fully functional PV system with connection to the building electrical system.

Government Acceptance Period: Box 13.d. of the SF 1442 shows: d. Offers providing less than _____0________ calendar days for Government acceptance after the date offers are due will not be considered and will be rejected . Offerors must list the number of days in Box 17 (page 2) of the SF 1442.

Is this (that is, “0”) the correct government acceptance period?

This number should be 90 calendar days.

There is no specification for HVAC temperature controls, is there a facility control manufacture that must be used for this work?

AE RESPONSE: Specification Section 23 09 23 ‐ DIRECT DIGITAL CONTROL (DDC) SYSTEM FOR HVAC has been added to the Project Specification, and is attached.

Drawing S4 indicates that the trellis is by others but there is a specification Section 107353 for this work. Is the trellis a part of this project to be included under the base bid? NPS RESPONSE: Trellis work is part of the base bid.

Drawing sheet 71 of 195 A5 Titled Temporary Visitor Center

Plan and Notes shows dimensions of this structure as 70’ x 98’.

Specification Division 13 – Special Construction 133423

Modular Building and drawing notation #7 stipulates that product could be a purchase or lease item. These dimensions as shown leaves no alternative but to purchase this modular temporary structure. In lieu of utilizing fleet goods, which could

ONLY be obtain from a new production. Would it be acceptable to provide this temporary modular structure dimensioned slightly different but maintaining the configurated floor plan

NPS RESPONSE: Yes. The Contractor may submit a proposed design which may vary from the plan but which is close to the space and configuration shown.

Will this temporary visitors center modular structure require a fire suppression sprinkler system as it exceeds 5000 sf.? Due to

CORVID 19, we were unable to ascertain any definitive information, on this matter, from the Maryland State Fire

Marshal’s Office.

A fire suppression system is not required.

A/E RESPONSE: The National Park Service (NPS) is the authority having jurisdiction (AHJ) for this project, not the Maryland State Fire Marshal. NFPA 1 (Sections 4.4 & 4.5) and NFPA 101 (Sections

12.3.5, 36.3.5, 38.3.5) are the Fire Code and Life Safety Code for this project and building as adopted by NPS Directive NPS‐58. NFPA 1 and NFPA 101 does not require automatic sprinkler protection for extinguishment for life safety for this temporary non‐separated multiple occupancy (Assembly, Business and Mercantile) use building and NPS directives do not require automatic sprinklers to satisfy any property protection requirements.

Additionally, as a clarification to Specification Section 13 34 23 ‐ Modular Buildings, Item 2.2.V.13: A fully functional and com;liant fire detection and alarm system with complete smoke and fire detection shall be provided by the Contractor for all rooms and spaces per NFPA 72 and 101.
