GENERAL DESCRIPTION OF WORK:

Architecture & Engineering (A&E) Design Services for a Project to Reconstruct Rafinesque Hall Cave Trail within Mammoth Cave National Park, Edmonson County.

SCOPE OF SERVICE REQUIREMENTS:

Task 1: Update Trail Construction Drawings and Specifications for "No-Dig" Requirements Objective: Revise construction drawings and specifications to reflect "No-Dig" requirements for Rafinesque Cave Trail, ensuring alignment with SHPO and NPS historical and archaeological standards.

Scope:
• Review all existing 100% construction drawings and specifications.
• Revise both drawings and specifications to clearly state that all work must remain on the surface layer without excavation, grading, or subsurface alteration.
• Defining the starting point of the "No-Dig" approach at the existing trail edge near Little Bat Avenue and extend forward along the trail. A conference call will be held following NTP to confirm the limitation of “no-dig” areas.
• Specify surface-only installation of pavers and lint guards using approved, non-intrusive anchoring methods.
• Submit updated drawings and specifications to the park for review and approval.

Task 2: Incorporate Constraints into Updated Documents

Objective: Ensure the revised drawings and specifications reflect all constraints necessary to protect historical and natural features.

Scope:
• Integrate SHPO requirements for maintaining visibility of natural features and avoiding direct lighting impacts.
• Ensure trail alignment and gather space expansion remain within previously developed and cleared areas, as shown in Attachment 1 (NPS is to provide Attachment 1 prior to beginning of the re-design).
• Submit updated documents for Park review and comments, with revisions applied as needed.

Task 3: Finalize Updated Construction Document Package

Objective: Deliver a fully-up-to-date construction document package, incorporating all Park feedback and finalizing both drawings and specifications.

Scope:
• Incorporate final Park and SHPO feedback into both specifications and drawings to address all constraints and requirements. Park is to coordinate with SHPO.
• Submit a finalized package in combined PDF format and individual files, including updated specifications and drawings.
• Ensure all final drawings retain the original engineer’s seal and date from the initial 100% CDs, where applicable. NPS is to clarify if all sheets are to be redated, or only the revised sheets.
