SERVICE GENERAL REQUIREMENTS

PART 1 – GENERAL

ITEM 1 – LOCATION AND DESCRIPTION OF WORK

1.1 Background: This work entails the hydro-flushing, hand clearing & mechanical / hydro vac-excavation three impounded stone culverts, Located on property within National Park property on Scenic Drive RT10 at Theodore Roosevelt National Park’s, North Unit; 15-miles south of Watford City. The subject culverts are described in maps and photographs at the end of this document.

The three culverts constructed in 1933 undergird a two-travel lane public asphalt throughfare that provides park visitors access to the park scenic tour, and staff access to various areas within the park unit. This road is scheduled to be reconstructed in the next several years. This work will provide Engineers and Design Contractors access to the subject culverts for the inspection of conditions, surveying of dimensions, and develop plans for repair (or) replacement during the road renovation being designed.

As part of this work, the culverts and their immediate inflow and outflow basins up to fifty feet beyond the ends of the ductwork (50-feet in each direction) both upstream and downstream shall require minor contour excavation and grading to manage outflow and inflow hydraulics effectively. Larger trees adjacent to the immediate work area have been removed by NPS Personnel, smaller trees 3” or smaller Diameter at Breast Height may need to be selectively removed by contractor, as well as shrubs and underbrush along adjacent embankments.

All outlet contours at drainage ends of the culverts will be graded to conduct water smoothly into the culvert ducts, through the ducts and away from the duct outlet apertures along adjusted embankments, and natural drainage features to restore normal water flow per the intention of the original design.

This work has not been accomplished in several years, accordingly some of the culverts are partially or fully impounded. Contractor will be expected to use due care to avoid damaging further than current any culvert masonry by, tool, hand or machine(s). Culverts will be cleared to their masonry or earthen floors without undermining the spring line of the arch’s wall or foundation.

Please note that general GPS coordinates are provided for the culverts that identify the locations to assist offerors in locating the work areas, but do not encompass the extant of the work as described above.

Please note All ductwork sizes are estimated in approximate dimension.

6.2 Plan of Action – NAGPRA - Native American Graves Protection and Repatriation Act – In the event NAGPRA artifacts are encountered:

If suspected human remains and/or other NAGPRA-related objects (funerary objects, sacred objects, or objects of cultural patrimony) are discovered as a result of the current undertaking, project activity within 100 feet of the location of the discovery will cease and the area will be protected from further disturbance until an expert on human skeletal anatomy can arrive on site. This expert will be aware of the project to help ensure their availability to arrive within 48 hours of the discovery. Upon arrival, if needed, soil will be removed around the remains by hand tools to the point of identifying whether the remains are human and of a Native American individual(s). If Native American human remains and/or NAGPRA-related objects are identified, the park superintendent will be notified immediately. The superintendent will promptly notify Tribal representatives of the discovery by telephone. Within 24 hours, the superintendent will notify the Tribal contacts in writing to provide information on the geographical location, contents of the discovery, and steps taken to secure and protect the remains and/or cultural items. No later than three days after receiving written documentation of a discovery of Native American human remains and/or NAGPRA-related cultural items, the superintendent will make reasonable efforts to secure and protect the human remains or cultural items; verify that any activity around the discovery has stopped; and notify and consult with potentially culturally affiliated Tribal representatives.

Following Tribal notifications/consent:

1. Native American human remains and/or NAGPRA-related cultural items will only be recorded to the extent necessary for ongoing consultation.

2. For avoidance of the area in the future, a GNSS device will be used to map the general site location.

3. No soil samples of the burial feature will be taken.

4. No photographs of human remains and/or NAGPRA-related cultural items will be taken.

5. Any additional non-destructive documentation of the remains and cultural items will only be carried out with the consent of Tribal representatives.

6. All documentation will be considered sensitive and for internal use only.

The primary objective is to leave human remains and/or NAGPRA-related objects in situ. In a case in which these remains or objects need to be relocated, the NPS will do the following. Upon consultation with Tribal representatives, the human remains and/or any NAGPRA-related objects will be exhumed and stored at a secure, climate-controlled location at THRO. These will not be accessioned or cataloged.

They will be kept in natural materials, such as muslin and boxes with minimal metal or labelling, pursuant to the Tribes wishes. These will remain in the care of NPS, but not as property or custody, until disposition occurs.

ITEM 7 - PROJECT CLOSEOUT

7.1 Cleaning: Remove all tools, equipment, surplus materials, and rubbish. At time of final inspection, project shall be thoroughly clean and ready for intended use.
