Questions & Answers / Clarifications

This document provides responses to vendor questions regarding solicitation 140P4226R0005, clarifying various aspects of the project requirements, specifications, and proposal submission.

• Elevations and Access: Item #04-05 refers to all elevations. North elevation access is at the contractor's discretion (pending NPS approval), while the South elevation requires scaffolding due to archaeological structures.
• Scaffolding vs. Lift Access: Scaffolding cannot be built on top of overhead protection along 6th Street. If scaffolding is proposed along 6th Street, full pedestrian access must be maintained.
• Sister Company Experience: Past experience from sister companies is permissible if it meets RFP requirements, provided a narrative detailing the corporate structure and relationship is included.
• Project Magnitude: Projects below $1M in magnitude can still be considered relevant experience.
• Masonry Repointing: Experience with masonry repointing/restoration projects is relevant even if they do not involve chimney flue lining, provided other criteria (e.g., historic significance, urban setting) are met.
• Plaster Scope: All plaster repair has been removed from the scope of work; references to interior plaster damage repair are deleted from the solicitation.
• Grouting Depths: Actual measured depths for grouting will be paid under the unit price (CLIN 5). Bidders should refer to the solicitation for NTE quantities and bid instructions.
• Seasonal Restrictions: The prohibition on work from Memorial Day to Labor Day 2026 applies only to 2026. For 2027, restrictions revert to standard park operating conditions, including a limited restriction around July 4th.
• Stone Masonry Restoration: Specification 04 01 40.91 addresses potential incidental stone masonry restoration. No discrete bid quantities or locations are established; such work will only be performed if directed or approved by the Contracting Officer/Architect.
• Exterior Washing: Exterior cleaning is limited to localized areas for specific conditions (efflorescence, biological growth, repair areas) and not a full façade-wide requirement.
• Bid Guarantee: A bid guarantee is required, as clarified in Amendment 0003.

These clarifications provide essential details for bidders to accurately price and scope their proposals, particularly concerning project requirements, materials, personnel qualifications, and site access.
