1. HEADSTONE/MARKER REQUIREMENT

C.7 HEADSTONE/MARKER REALIGNMENT, RESETTING, BACKFILL

C.8.1 Overview: This section outlines Upright Headstone/Marker realignment requirements.

Raise, Lower, Realignment, Reset, Clean and Backfill services consist of extracting, resetting, aligning, backfilling and tamping/compacting upright headstones that are already in place which have shifted out of vertical and/or horizontal alignment and plumb, as well as inventorying and assuring accurate placement of gravesites at the National Cemetery. The Contractor shall provide all supervision, professional advice/guidance labor, parts, materials, equipment, and personnel necessary to provide the services defined herein.

C.8.1a. Some sections are inground crypts with the headstone resting on the crypt edge, these will be identified by the COR. (Section 18)

C.8.2 Phasing and Work Sequencing: All work is to be accomplished in a sequential manner, with work limited to no more than six (6) burial rows of a section at any given time to minimize overall disruption to the cemetery. Requests to work on more than six (6) rows in a section at one time or move to another section before finishing previous section may be submitted to the

COR for approval. Approval/disapproval will be based on the impact to the cemetery operations and the progress and workmanship of the contractor, as determined by the COR. Work cannot begin in subsequent rows until such time that work has been completed in prior areas. Submit proposed project work schedule sequence for COR review and approval prior to start of project.

C.8.3 Record Keeping and Reporting: The Contractor's Project Manager Designee shall provide the COR(s) with weekly written accurate reports detailing the section and range of graves in that specific week. These lists will be provided on not less than a weekly basis, and shall identify all the above work that took place within the previous seven calendar days. Upon request, the

Project Manager will also provide a plan of action for the upcoming week, regarding headstone/marker locations and specific areas where work is being scheduled to occur.

C.9.1 Upright Headstone Specifications: Raise, lower, realign, reset, and backfill of upright headstones shall be accomplished as follows:

(a) Standard upright marble headstones are approximately 42 inches long, 13 inches wide, 4 inches thick, and weigh approximately 230 pounds. Contractor will immediately report any pre-existing damage to the COR.

(b) All temporary markers, floral, commemorative, buried permanent floral vases, or other types of decorations and arrangements causing interference with the raise and realignment of upright headstone operation shall be carefully, and in an orderly manner moved from, and per completion of work, moved back to all gravesites by the Contractor. Prior to removal, the

Contractor shall verify the numbering sequence and location of the headstone and associated decorations by using tags and a permanent ink marker indicating from which grave the item was removed.

(c) Headstones will be removed from their sockets by using wooden, and or metal clamps. If metal clamps are used the area that contacts the headstone must be protected with a rigid fabric that will prevent damage to, and marking of, the headstone. Clamps may be attached to a Bob

Cat or similar Machine to extract headstone from socket. Extreme care will be used not to scratch or damage headstones in any manner. Contractor is responsible for restoring all damages caused to turf and headstones during performance of this work. Headstones are to be raised, realigned, and lowered in the following manner:

(1) All headstones are to be extracted from the socket. ALL sockets are to be re-dug by hand to allow for a 3” perimeter around all sides of the headstone and to a sufficient depth so that a

3" compacted base can be established, allowing the stone to extend out of the ground at a height of 24-26 inches to the top of the arch on the standard headstone (Note: In areas where smaller than standard size headstones may occur, Contractor shall coordinate specified measurements and dimensions of required work with COR.)

(2) Moistened Crushed Limestone Base Material (graded aggregate sizes ranging from crushed fines up to ¼" maximum) will be placed around all sides of the headstones and in the bottom of the socket before being thoroughly tamped to full compaction at each three (3) inch vertical interval, leaving the last 3 inches at the top to have tamped topsoil. The government will not provide any material. The Contractor is required to provide these materials. (Note:

Moist Class II Road Base may be considered as an alternate. Contractor shall obtain approval from the COR for any substitute base material).

(3) Straight Rows: Headstones shall be set vertically plumb in all directions, in all cases in a line vertically and laterally, and where possible transversely (coordinate with

COR), with headstones of other graves using a top string, a back of headstone string line, and a side of headstone string line. Maximum vertical, lateral, and transverse tolerance of any headstone off the alignment string lines and/or marks shall be 1/8" or less. All measurements and string line set ups shall be taken from established section layout control points, not from previously set headstones, unless otherwise directed by the COR. In situations whereas there is no monumentation, a top string shall be centered over the arc of the headstone for vertical alignment. The consistency of the row will be used as the medium. At no time, will any headstone be reset in a totally new socket unless otherwise directed by the COR. Raised and realigned headstones in all soil and terrain shall be firmly in place so that headstones are rigid with no give or play.

(4) Irregular Terrain: When sloping and uneven ground conditions exist in burial sections, all headstones and markers will be set at field approved heights and levels using multiple keystones, back strings, top strings, and side strings to provide a flowing transition through uneven terrain. Field guidance will be provided by the COR upon the written request from the Contractor. The established field guidance will overrule the height requirements that will be found in other parts of this specification.

(5) Handling of Headstones: Prior to ANY removal of the existing headstones or makers from any row, the Contractor MUST verify to the COR’s satisfaction that permanent gravesite control monumentation has been established AND approval of the Contractor provided as-built drawings has been obtained IN WRITING from the Contracting Officer and/or the

COR’s.

(6) In cases where headstone sockets need to be realigned/shifted, and/or re-dug, the headstone sockets (holes) to receive headstones shall be dug by hand and/or mechanical devices to a sufficient depth so that 24-26 inches of the headstone is extending from the topsoil level of the sod to the top of the arc on the headstone. Contractor shall not dig a headstone socket wider than twelve (12) inches, twenty (20) inches in length, or exceed a depth of 20 inches that may cause the headstone to settle below height requirement.

(7) The measurements between rows of headstones and headstones within each row may differ from one section to the next, discuss with COR where this is found to occur. These measurements must be adhered to as closely as possible. Some variances may be allowed to keep a uniform appearance of headstones being aligned. Headstones will be accurately and precisely reinstalled on the correct gravesites with the utilization of temporary grave plotting maps, existing permanent control markers where available and temporary Contractor installed control markers accurately and precisely installed at the ends of each gravesite row.

(8) The realign crew is to start on a row of headstones close to the center of the section to be realigned. Headstones are chosen to be "key" stones. These keystones are ones that are visibly in line with most the rest of the headstones in the row, and are as close as possible to the proper measurements for that section of headstones. "Key" stones are to be chosen and utilized at a maximum of every 10th headstone (or more frequently in areas of rolling terrain). These keystones are then aligned by leveling front and back and side-to-side, and raised or lowered to a height of 24-26(or other measurement designated by COR) inches above topsoil level (this includes topsoil on sod).

(9) At the start of work in each burial section, the first row of reset/realigned headstones in each burial section is to be inspected by COR for appearance, spacing, depth, alignment, plumbness, height, accuracy, and smoothness in grade transition. No further setting of headstones shall be done until this first row has been inspected and accepted by the COR. It is the Contractors responsibility to notify the COR 24 hours in advance of when each of these inspections will be needed.

(10) Tape measures and Heavy strings or lines must run along the backs, sides, and tops of these keystones. The Contractor shall mark the lines with the proper measurements for the section being aligned. All remaining headstones in the row are then aligned along the strings front to back and side-to-side even with the measured marks on the line. Each headstone is leveled and plumbed front to back and side-to-side keeping the back of the headstone along the string and the side of the headstone along the measured mark. Maximum vertical, lateral, and transverse tolerance of any headstone off the alignment string lines and/or marks shall be

1/8", or less. Each headstone is also raised or lowered as necessary to ensure a uniform measurement of 24-26 inches above topsoil level to include topsoil of sod. The headstone is then aligned along the string front to back and side-to-side even with the measured mark on the line. The headstone is leveled and plumbed front to back and side-to-side keeping the back of headstone along the string and the side of the headstone along the measured mark.

(11) The alignment of the headstones shall be checked frequently during this process because the tamping may move the headstone out of level or off the mark on the line. This process of raising and realigning is repeated for each row of headstones. Upright headstones in all completed work areas shall be firmly set and anchored in place with no movement from forces subjected by the COR.

(12) Any upright headstones broken or damaged by the Contractor shall be reported to the

Cemetery Administrator or COR by close of business each working day in order that the grave can be properly marked. The Contractor shall be responsible for the cost of the headstone replacement. All headstone replacements must be coordinated with the COR. Any grid or sectional monuments disturbed, displaced or broken shall be replaced by the

Contractor at his cost. All grid or sectional monuments disturbed, etc., shall be properly reset by a licensed land surveyor at Contractor's expense. Curbs, roads, walks, turf, trees, utilities, etc. existing above and below the ground that are damaged or disturbed by the Contractor during performance of contract work shall be repaired at the expense of the Contractor.

Repairs to the above shall be corrected by the Contractor within fourteen (14) workdays, unless otherwise agreed to with the COR.

C.10 Flat Marker Re-installation: The grave markers will be re-installed in the following manner:

C.10.1 Flat Markers are approximately 24” (inches) long, 12” (inches) wide, 4” (inches) thick and weight approximately 130 pounds. Prior to ANY removal of the existing markers, the contractor MUST verify that the permanent gravesite control monumentation are established.

C.10.1a Phasing and work sequencing for flat markers:

Contract work shall be accomplished in a sequenced manner, with work limited to occurring in no more than three (3) rows at any given time in order to minimize overall disruption to the cemetery. Requests to work on more than three (3) rows at a time may be submitted to the COR for approval. Approval/disapproval will be based on the impact to the cemetery operations and the progress and workmanship of the contractor, as determined by the COR. Work cannot begin in subsequent rows until such time that work has been completed in prior areas. Submit proposed project work schedule sequence for COR review and approval prior to start of project.

C.10.2 Grave markers shall be installed using finished elevations and grades. All measurements and string line set-ups shall be taken from burial gravesite control monumentation previously established, not from previously set flat markers, unless otherwise directed by the COR.

C.10.3 The contractor will pull the flat markers from the flat marker sockets and carefully place the markers on each associated gravesite(marker must not leave individual graves). The fill material and existing grasspave material will be pulled and removed from site. The trench will be releveled and refilled with road base material and brought up to grade. and then backfill with

5” min thickness of moistened Crushed Limestone or approved Road Base Material (graded aggregate sizes ranging from crushed powder fines up to 3/4” maximum) heavily tamped to full compaction and leveled for the required alignment of the flat markers. After heavily tamping and compacting the soil in the bottom of the continuous trench, install the continuous strip of new GRASSPAVE 2 along the entire length of each flat marker row beginning at the edge of the first flat marker and continuing until reaching the far edge of the last flat marker in the same row.

If material must be spliced, this shall be done in accordance with GRASSPAVE @ manufacturers instructions. Directly underneath each flat marker, backfill the honeycomb voids of the GRASSPAVE 2 with moistened Crushed Limestone Base Material (graded aggregate sizes ranging from crushed powder fines up to 3/8” maximum) to fill the 1” high rings and all spaces between the rings, and compact this material into place. Top elevation of the filled

GRASSPAVE 2 material will be the base for the flat markers. Backfill clean topsoil into the remaining areas of GRASSPAVE 2 honeycomb located in the trenches between the flat markers and firmly compact this material into place. Remaining trench areas around and between all flat markers from top of the GRASSPAVE 2 to top of ground surface are to be filled with 3” minimum clean topsoil compacted firmly into place so that settlement will not occur.

C.10.4 Backfill material specified above shall be used at all areas within the gravesite requiring backfill material . The backfilled material shall be placed under the GRASSPAVE2 and compacted as recommended by the GRASSPAVE2 manufacturer. The backfill material shall also be used at any other areas within the gravesite to form a level surface and/or surface positively draining to existing storm drains within the cemetery. The backfill material which is

NOT located under the GRASSPAVE2 material shall be compacted to 85% as measured by

ASTM D1557, Method A. Upon installation of the required topsoil and sod, the flat marker shall be set at one inch above the finished grade, which include the topsoil of the sod.

C.10.5 Flat markers shall be set firmly in place so that the markers are rigid with no give or play. And set 1 inch above graded soil line that includes topsoil of sod.

C.10.6 Flat markers shall be set plumb, in a line laterally, transversely, and diagonally with markers of other graves. All measurements and string line set-ups shall be taken from the established permanent gravesite control monumentation, not from previously set flat markers, unless otherwise directed by the COR(s).

C.11 Headstone/Marker Cleaning:

The VA is the authority on determining what is clean and what is not clean. The definition of a “clean stone” is that the stone has no dirt lines or watermarks and no visible signs of fungi.

Cleaning will be accomplished with the use of a high-pressure washer (pressure not to exceed

800 PSI) and an acceptable cleaning agent that that does not harm the stone and that is environmentally acceptable. The cleaning will consist of the removal of stains, dirt, grass, or fungi leaving the marker undamaged and in a clean, acceptable condition. Will be completed with the use of a high-pressured washer (not to exceed 800 PSI) and an acceptable cleaning agent that doesn’t harm the grave marker and/or turf. The cleaning will consist of the removal of stains, dirt, grass, or fungi leaving the marker undamaged and in an acceptable appearance.

Cleaning may be completed either before storage of the markers or after re-installation. If cleaning is accomplished after re-installation, the Contractor shall be responsible for any turf or sod damaged during the cleaning process. The Contractor shall be responsible for any turf or sod damaged during the cleaning process.

C.12 Guaranty: The Contractor shall guaranty all work for a period of one year (365 calendar days) after final inspection and acceptance of the entire project by the Government. Any headstone adjust, realign, reset, and/or backfill workmanship that does not meet the specified requirements (including specified tolerance requirements) at the end of this guaranty period is to be reworked, adjusted, and corrected by the Contractor at no additional cost to the government.

Remainder of all other work related to this project is to be warranted for a period of one (1) year after final acceptance by the government. Work performed under the Guaranty shall be corrected within ten (10) workdays from receipt of notification or as directed by the COR.

C.16.1 Vegetation Removal: Existing turf is to be sprayed with a short acting herbicide designed to eliminate turf and weeds (i.e. “Round-up” or equivalent). All existing turf and weeds must be eradicated before stripping of topsoil and dead vegetation. Application to be applied by a licensed applicator to ensure appropriate rates of application and other State regulated requirements.

C.16.2 Stripping Topsoil: Strip two (2) inches of topsoil from within limits of work area and remove from work site each day. New topsoil shall be a fertile, friable, natural topsoil of loamy character and characteristic of locality. Topsoil shall be capable of growing healthy horticultural crops of grasses. Stockpile topsoil and protect as directed by COR or designee. Eliminate foreign materials, such as dead grass, weeds, roots, stones, subsoil, frozen clods, and similar foreign materials larger than 25 mm (1 inch) in any dimension from topsoil that will be used in final grading. Topsoil work, such as stripping, stockpiling, and similar topsoil work shall not, under any circumstances, be carried out when soil is wet so that tilth of soil will be destroyed. Topsoil removed from the work area may be stored in a temporary on-site location designated by the

COR(s) until removal from cemetery site at the end of work day.

C.16.3 Lines and Grades: Area must be tilled, graded and compacted to a level to provide a flowing transition through existing terrain (no depression or low line areas). A Registered

Professional Land Surveyor or Registered Civil Engineer, shall establish lines and grades for approval by COR and designee. Grading shall provide a smooth transition at curbs, trees, planters and uninterrupted drainage flow into existing drains. Contractor shall notify COR or designee of any differences before requesting approval of lines and grades. Subsequent to establishment of lines and grades and COR or designee approval, Contractor will be responsible for any additional cut and/or fill required to ensure that site is graded to insure that surface water drainage will drain to existing storm drains and that they are no standing water areas throughout the sections ( such as depression and sunken graves).

C.16.4 Filling and Back filling: Do not fill or backfill until all foreign materials have been removed from excavation. For fill and backfill use excavated materials and top soil as applicable.

Do not use unsuitable excavated materials such as topsoil, construction materials and material subject to decomposition, clods of clay and stones larger than 1 inches, organic materials including silts which are unstable, and inorganic materials including silts, too wet to be stable.

C.16.5 Compaction: Compact with approved tamping rollers, sheep-foot rollers, pneumatic tired rollers, steel wheeled rollers, or other approved equipment (hand or mechanized) well suited to soil being compacted. Do not operate mechanized vibratory compaction equipment, which may damage existing liners or caskets. Sub-grade must be thoroughly tamped to compaction.

C.16.6 Topsoil: Topsoil shall be a well-graded soil of good uniform quality. It shall be a natural, friable soil representative of productive soils in the vicinity. Topsoil shall be free of admixture of subsoil, foreign matter, objects larger than 25 mm (one inch) in any dimension, toxic substances, weeds and any material or substances that may be harmful to plant growth and shall have a pH value of not less than 6.0 nor more than 7.0. Testing for pH will be required by an approved laboratory. Copies of the pH tests shall be furnished to the COR(s) PRIOR to topsoil being placed. Amend topsoil not meeting the pH range specified by the addition of pH Adjusters.

Top-dress is to be organic matter, weed free consistent with irrigation requirements to promote healthy grass. If sufficient topsoil is not available on the site to meet the depth as specified herein, the Contractor shall furnish additional topsoil. At least 10 days prior to topsoil delivery, notify the COR or designee of the source(s) from which topsoil is to be furnished. Obtain topsoil from well-drained areas.

C.16.7 Installation of Topsoil: After tilling the soil for bonding of topsoil with the subsoil, spread two (2) inches of topsoil evenly over prepared site. Incorporate topsoil into the subsoil to avoid soil layering. Do not spread topsoil when it is excessively wet or dry. Correct irregularities in finished surfaces to eliminate depressions. Protect finished topsoil areas from damage by vehicular or pedestrian traffic. Complete lawn work only after areas are brought to finished grade. The areas within the drip lines of existing trees are not to be tilled at a depth greater than three inches or backfilled not to exceed four inches from existing grades. Contractor must protect all trees, shrubs and plants. Exceptions must be approved by COR.
