PART 1 – SUMMARY OF WORK & DEFINITION OF CLINs

1.1 WORK COVERED BY CONTRACT DOCUMENTS

A. General: All work outlined below will be performed under a single contract.

B. Project Location: This project is located at the Old Chief Joseph Grave Site at the Old Chief Joseph Memorial and Gravesite in Joseph Oregon (no physical address) (Lat/Long 45°20'11.47"N 117°13'19.26"W)

1. Project Background: In 2021, the wall fronting the Old Chief Joseph Cemetery was damaged in a single-car automobile accident. This accident caused a moderate amount of damage to one of the standing pillars at the end of the cemetery wall. This damage included the separation and collapse of approximately a quarter of the pillar. This damaged piece of the cemetery wall is mostly in-tact with a small number of stones that separated from the pillar and the broken pillar piece.

The National Park Service (NPS) currently does not have the capacity to conduct the repair of this cemetery wall in 2024. Due to this, the National Park Service seeks to contract with a third party to repair and restore this section of the cemetery wall and document the repair. The section of wall and pillar to be repaired is approximately 7’ x 3’ x 3.5’ and must be repaired in a manner that is consistent with the Secretary of the Interior’s Standards for Historic Preservation.

C. Project Scope of Work / Definition of Contract Line Items: The Work consists of the following:

1. Contract Line Item 010: This item shall consist of the stabilization and repair of the broken column/wall and the documentation of the repair process and the completed repair

Contractor will provide lump sum pricing for contract line items.

D. Contractor Tasks: The Contractor is to provide all labor, equipment, and materials to repair and document the repair of the cemetery wall/column.

Work shall include but is not limited to:

1. Demonstrating understanding and experience working with historic properties and conducting repairs on historic structures.

2. Conduct a preliminary trip to Old Chief Joseph Cemetery with NPS staff present to inspect the wall to determine the extent of damage to the mortar and stones that are/were part of the cemetery wall.

3. Document the noticeable damage to the wall that has occurred due to weathering that has occurred since the wall was damaged via automobile in 2019. This documentation shall consist of photographic documentation that clearly shows the damage, the size of the damage, the cause of the damage, and the location of the damage. The documentation shall also consist of a narrative description of the damage being documented.

4. Transport the damaged wall pieces, mortar, and elements from storage at Nez Perce National Historical Park’s maintenance shed from Lapwai, ID to Joseph, OR for inclusion in the repair of the cemetery wall.

Nez Perce National Historical Park

Old Chief Joseph Century Rock Wall Restoration

A. Introduction

The Old Chief Joseph Cemetery (OLJO) is located immediately south of the community of Joseph, Oregon near the north shore of Wallowa Lake. The 5-acre site is held in trust by the BIA for the Nez

Perce Tribe (NPT) and Confederated Tribes of the Umatilla Indian Reservation (CTUIR). The property was formerly owned by the Cooperative Farmers Ditch Company who transferred ownership of the property to the U.S. Government in 1923. The property was used by Nez Perce descendants as a burial area prior to the land transfer with the earliest marked grave being the 1897 grave of Sarah McFarland. In 1926, the remains of old Chief Joseph were relocated to the site from his original burial location near the

Lostine River.

The late 1930’s brought many improvements to the cemetery. Much of the built landscape was constructed by the Umatilla Civilian Conservation Corps Indian Division (CCC-ID) from 1938 through

1941. Projects conducted by the CCC-ID at the cemetery site were construction of a circular drive, stacked rock boundary wall, wire boundary fencing, irrigation and water conveyance systems, a drinking fountain, a concrete cistern, and vegetative plantings.

The most recognizable feature of the CCC-ID work on the site is the stacked rock wall that defines the northeastern boundary of the cemetery. The rock wall consists of two sections flanking either side of the cemetery entrance. At the cemetery entrance each of these wall sections (north section and south section) have stacked rock pillars that are capped with roughly square shaped concrete caps. Stacked rock pillars are also located at the opposite ends of each of the wall sections. The terminal pillars are smaller than those found at the cemetery entrance and did not exhibit the concrete cap (Figure 1 & 2).

The OLJO site has numerous historic preservation designations denoting the site’s regional and national level of significance. In 1989 the site was individually listed as a National Historic Landmark (NHL) and was included in 1992 as one of 38 units of Nez Perce National Historical Park. The site is listed on the

National Register of Historic Places as a component site of Nez Perce National Historical Park, and a

National Register eligible cultural landscape for the CCC-ID built features existing on the property. The site is also the congressionally designated beginning point of the Nez Perce National Historical Trail and a component of the Hell’s Canyon All American Road.

In the late summer of 2019, NPS crews conducted extensive preservation maintenance work on both the northern and southern sections of the OLJO stacked rock wall. This work was funded under an agreement between the Oregon Department of Transportation, CTUIR, NPT, and the NPS. Conducted under the direction of Gary Zybell, former head of the masonry division for the National Conservation and Training Center, the project focused on stabilizing and repairing degraded portions of the rock wall.

Preservation work consisted of repointing and replacement of deteriorated mortar and reinserting rocks that have become dislodged from the wall through mortar failure. Work also focused on reinforcing the wall in several key areas where it had separated due to ground shifting through frost heaves, foundation settling, and/or tree root growth. Large sections of the deteriorated concrete wall cap were also repaired and stabilized.

B. Damage to Stacked Rock Wall

In the spring of 2021, a one-vehicle accident resulted in damage to the southern most section of the historic stacked rock wall. A vehicle was traveling south bound on the highway paralleling the cemetery at an excessive speed. While attempting to navigate the slight left-hand curve the driver lost control of his vehicle and veered off the roadway hitting the soil embankment along the edge of the rock wall and careening into the extreme southern end of the wall. This resulted in the full force of the vehicle striking the southern-most end pillar nearly head-on. The end pillar was heavily damaged in the accident. The vehicle impact dislodged a large portion of the top section (Figure 3) and heavily damaged the east side

(Figure 4) of the end pillar. The west side (Figure 5) of the end pillar (on the cemetery side) remains mostly intact except for the top damage as discussed above. Figure 1 below shows the same pillar (from

2012) before the vehicle accident. An inspection of the wall by NPS staff several days after the accident occurred revealed that damage was solely confined to the southernmost end pillar and the overall structural integrity of the remainder of this section of wall was not affected by the vehicle collision.

C. Restoration Options

As discussed above, a large section of the upper portion of the southern end pillar was dislodged by the collision but remains intact. This portion of the stacked rock pillar still remains mortared together and seems to have maintained its structurally integrity (photo xx). In consultation with tribal representatives, it was determined the best course of action would be to attempt to rebuild and restore the pillar as close as possible to the original condition. In reviewing the post-accident condition of the end pillar, the nature of its original construction, and the way the pillar broke apart as a result of the collision two options for restoration seem feasible.

1. The first option is to attempt to reset the large, intact upper portion of the end cap back into place on top the lower section of the pillar. This will require lifting and supporting the top section in place and then rebuilding the supporting structure below through replacing dislodged rocks and mortaring them back together.

2. The second option is to attempt to rebuild the damaged end pillar from the intact base on up. This would require disassembly of the dislodged upper section of top pillar through manual removal of the mortar around the stones. Once completed the entire pillar could be rebuilt using stones dislodged from the existing base along with those from the disassembled top fragment.

Through onsite examination of the damage by NPS staff and consultation with tribal representatives it was determined to proceed with option one – resetting the dislodged top portion of the pillar back to its original location and then reassembling the middle section of the pillar with dislodged stones . This would effectively connect the original top section to the existing base of the pillar resulting in only the middle portion of the pillar being rebuilt.

This option is preferred for three primary reasons. 1) It retains as much of the original fabric (both stones and mortar) as possible; 2) Once properly set and realigned, it allows for restoration of the rock pillar with the majority of the rocks in their original location and orientation; and 3) disassembly

(through chipping out the existing mortar) of the top fragment required for the second option is likely to result in damage to the stones and may also result in a less accurate restoration process.

D. Proposed Process for Restoration

Through careful examination of before and after photographs we can identify the original location and orientation of the upper section of the damaged end pillar. Though the majority of the upper section of the pillar remains intact, much of the rocks and mortar in the middle of the pillar (especially the east side) was heavily damaged and broken apart by the vehicle accident. It is believed that many, if not all, those rocks from the damaged middle section remain on site and with some effort can be reinstalled in their original location. It is possible some of these rocks will not be found or are too damaged to reuse and in those cases other local rocks of the same size can be gathered from the area and used in their place. As noted below some of the rocks are easily visible in before and after the accident photographs of the end pillar. We can use this photographic evidence to establish their original orientation prior to the damage which should make the overall restoration process much easier.

Note: For sections 1 and 2 below please refer to the photographs located in Appendix 1. This appendix includes two sets of photographs (A1 & A2 and B1 & B2) that can be used to determine the original orientation and location of the dislodged top part of the pillar.

1. In photo A1 are seven rocks numbered 1-7 and one rock labeled with an “A”. These numbered rocks are also visible and identified by the same numbers in photo A2 showing the dislodged top piece. Please note that the top piece displayed in photo A2 is sitting upside down (i.e. the original top of the pillar is now resting on the ground in this photo). Additionally, the rock labeled as “1” in photo A2 was originally located on the cemetery side of the pillar resting just above (or at the level of) where the concrete wall cap meets the undamaged end pillar in photo A1. The rock labeled in photo A1 as “A” is missing from the top piece displayed in photo A2 as depicted by the “A” in the open space near the ground.

2. Photo B1 shows the remaining portion of the bottom pillar after the vehicle accident. There are nine numbered locations identified on the damaged bottom section of the pillar. Photo B2 shows the dislodged top piece again with the corresponding locations identified by the same numbers as noted in photo B1.

What these two sets of photos depict is that the original orientation of the top piece can be easily ascertained, and that enough of the corresponding features, stones, and mortar pockets can be matched up between the dislodged top piece and the intact lower pillar to reset the top piece on the lower pillar in exactly the same orientation as it was previously. Once set in place (and possibly temporarily supported) the remaining stones for the middle section of the pillar can then be reinstalled and mortared back together.

Restoration efforts should start by attempting to reset the top piece in its original location and orientation first to see if there are enough common attachment points to allow it to be self-supporting.

This will require a tractor with a bucket, small crane, or a tripod support structure built over the lower pillar section with a chain hoist to lift and support the piece in position. For secure lifting the top piece will likely require installation of lifting points (i.e. bolts or pins drilled and set into the mortar joints) to attach chains or straps from the lifting device (tractor bucket, tripod with hoist, or some lifting mechanism) to allow for the dislodged piece to be lifted up, over, and set down on the damaged lower section. Note: If the top piece can be lifted by straps or some other device or system not requiring holes and installation of lifting bolts that would be preferable.

Once the “fit” of the top piece on the damaged lower section can be determined, mortaring of that piece back into position can begin. This will require applying either a thin coat of mortar or an exterior stone and masonry approved adhesive to all the interior mating surfaces between the top and lower sections.

Based on the pre-mortar set of the top piece, it may or may not require bracing to hold it in position until the mortar or adhesive cures properly. If bracing is needed it will likely be on the southern, Wallowa Lake and/or highway sides of the top piece as those experienced the most damage from the accident. The side of the pillar adjacent to the cemetery and where it meets up to the wall section likely will not require bracing because of the number of intact stones and the corresponding fitment points in common between the existing pillar and the top piece.

All rocks found around the accident site that likely came from the damaged pillar should be gathered and sorted on site. To the best extent possible (by using photographs of the end pillar prior to the accident) these remaining dislodged rocks should be reinserted where they originally were located. For those areas of the pillar where viable photos do not exist, the original rocks cannot be found and/or are damaged, or the original orientation of the rocks cannot be determined, new stones found in the local area should be used. Every effort must be taken to place these stones in the same manner and fashion as was done originally.

The external mortar on this end pillar is a rusty red color. Some of the internal mortar was a natural grey. The NPS has the mortar mix and color tint information to match the original rusty red and internal grey color from the 2019 restoration efforts. The red mortar should be used throughout the restoration process. There is no need to attempt to match the grey interior mortar as the red mortar is what is visible from the outside and the color used internally will not be visible.

If an exterior grade stone and mortar adhesive can be identified, then it can be used in cases where original rocks are being reinserted into existing mortar pockets. Or, in situations like those depicted in photo B1 and B2 #7 and #8 where two rocks were broken and half by the collision and a piece of the same rock is present in both the bottom pillar and the top piece. In these locations there will likely not be enough space to allow for an adequate layer of mortar to be placed to secure the stone in place. For situations like this, a thin coat of adhesive can be applied to the intact mortar pocket or broken stone surface to allow for the top piece to sit in its original orientation. The adhesive will be provide a stronger bond to the mating surfaces in a much thinner application than can be achieved with mortar. Adhesive application must be limited to the internal surfaces only. It should not visible from the finished, external surfaces of the pillar.

Once the internal mortar and/or adhesive has set all the external joints can be repointed around the stones. This will create a water-tight seal, cover any signs of adhesive usage, and return the pillar to a uniform appearance. The joint between the wall cap and the newly reconstructed end pillar should be inspected as well and repointed as needed. It is likely that some of the gray top cap of the wall section where it meets the end pillar will need restoration work to keep the seam where the two features meet tight and minimize water intrusion.

E. Documentation of Restoration Work

All restoration work should be carefully photo documented through every step of the process. Photo points should be established on all sides of the pillar to allow for a series of uniform photographs taken from the same locations on a routine basis to document restoration efforts. Other close-up and detail photos should also be taken to document restoration efforts not visible from the established photo points. A brief restoration report should be produced detailing the methods, all products used, and procedures implemented in the restoration efforts.
