RFIs 1-6 RFI #1 - There are river stones pressed into concrete bordering several of the work areas.

The vendor can reset any stones disturbed during construction, but the new concrete holding them may be a different shade than the existing concrete. We wanted to make the Government aware of this potential visual difference.

Answer 1 - Yes, we are aware it could be a different shade..

RFI#2 - Please confirm whether the area highlighted in yellow is required to be ADA compliant. The vendor noted that if this area must be ADA compliant, they may need to revisit the site to confirm feasibility and determine whether major excavation would be required.

Answer 2 - As is the plaza is ADA assessable now, so they are just replacing what is already in place. Replacement "In-Kind" we call it.

RFI#3 - Please confirm whether the area highlighted in red is included in the scope of work.

The vendor noted that granite pillars may restrict equipment access in that area, so they would need to plan accordingly if it is part of the required work.

Answer 3 - Yes, the area in red has blue stone and needs replacement. They can work around the cement pillars..

RFI#4 - The General section of the SOW reads: "This is a Firm-Fix Price (FFP) contract to provide the installation of a new concrete plaza at Old Slater Mill Campus (OSM) in place of an old blue stone plaza." This section also reads "Any items not specifically noted, but necessary for performance in accordance with accepted industry standards, shall be furnished under this IDIQ. The contractor shall perform to the standards in this contract.

In total, 1,850 square feet of blue stone will be removed and replaced with cement" Is this contract a FFP or an IDIQ?

Answer 4 – It will be a stand-alone, firm-fixed-price contract. Not an IDIQ.

RFI #5 - Section 1.4 Scope reads "and stamp the concrete to give a more appropriate and historic feel to the new plaza." Section 4.2 TECHNICAL REQUIREMENTS, subsection 4.2.4 Concrete Placement reads: "Be finished with a broom finish for slip resistance unless otherwise specified." The SOW reads as if the control will be stamped, then broom finished. Is that correct? Additionally, is the stamp style to match the existing layout?

Answer 5 - The stamp style is to recreate how the blue stone in place presently looks. You can use whatever means necessary to accomplish this.

RFI #6 - Are we to preserve and store the existing bluestone in a safe manner for NPS? Or are we to demolish and haul the material off?

Answer 6 - Demolish and haul off the old blue stone.
