140P2025R0092 Amendment 0002:

Questions and Responses:

1. CLIN 6 lists a quantity of 1 LF for the drainage system at the soldier pile wall. Is this in error?

Answer: LF is a typographical error and should read LS (Lump Sum). See attached revised Price Schedule.

2. Section 01 35 13.22 1.2 D – Archeological Monitor is defined as a representative of the contractor. Further down in 2.2 D – NPS shall provide the archeological monitor.

Answer: This is an error, the contractor is responsible for Archeological Monitoring services.

3. Seven (7) key trades are requested but projects are limited to five (5). Can the government please clarify how many projects each Key Trade needs to provide?

Answer: The project limit of 3 to 5 projects applies only to the Prime Contractor’s experience. For the seven Key Trades, the government is not requiring 3 to 5 projects per trade. Instead, the Prime Contractor should describe the experience and capability of the subcontractors/firms proposed for each key trade. This can be done via narrative descriptions or qualifications, not necessarily through formal project examples.

For key trades where the Prime Contractor is self-performing the work, list the Prime Contractor's experience in those trades within that limit (3–5 relevant projects).

4. Can the government please clarify which key trades need to provide the project experience form in the proposal?

Answer: Earthmoving Services, Concrete Services, Survey Services, Testing and Inspection Agencies, Archaeological Monitoring Services, Asphalt Services, and Landscape Services. However, the Prime Contractor should describe the experience and capability of the subcontractors/firms proposed for each key trade.

This can be done via narrative descriptions or qualifications, not necessarily through formal project examples.

5. Does the Project Manager and the Civil Site Earthwork manager required need to be separate persons?

Answer: This position can be the same person as long the qualifications can be met.
