Notify the Contracting Officer if impacts are anticipated.

7. In the event that natural features are inadvertently damaged, Contractor shall notify Construction Management Representative immediately.

K. Preservation of Cultural Resources

1. Due to the elevated historic status of this resource, preservation treatment approaches must concur with The Secretary of the Interior’s “Standards for the Treatment of Historic Properties,” along with The Secretary of the Interior’s Guidelines for Treatment of Cultural Landscapes.”

2. This property is a National Historic Landmark and it will continue to be managed as an important resource. It may contain historic features that include buildings, structures, landscapes and associated landscape features (sidewalk, planters culverts, fences, site walls, retaining walls, etc. and engineering features such as bridges, towers, lighthouses, etc.) It is also possible that certain site features within the project boundary are not mentioned in the NR document, but those unnamed items are considered potentially eligible and are treated with the same level of concern.

3. During construction, care must be taken to protect cultural resources. When planning construction means and methods, preservation and protection of this resource is paramount. Contractor will proceed with care, using conservative and cautious approaches when working on and around historic fabric. Recognized and approved methods, favoring hand tools over power tools along with demonstrated experience and skill, will take precedence over radical and unproven procedures. If potential exists for irreversible damage or loss of fabric, contractor will cease work and seek guidance and approval from CO (Contracting Officer) before resuming work. Actions deemed detrimental to the resource, that would otherwise place the resource at jeopardy of loss to its historical integrity, regardless of cause, will not be undertaken without prior review and approval by CO.
