PART 3 – PRODUCTS

3.1 INSTALLATION

A. Using the solvent cement [Eclectic UV-6800] formulated specifically for PVC, glue the aluminum logo cap [BMAC] to a 2-foot section of PVC pipe [5PVC24]. This will allow the glue to set while continuing with the following setting procedures.

B. Glue the PVC cap with a drill hole [TSSEC-Y] on one end of the 3-foot section of schedule 40 PVC pipe 1-inch (25mm) inside diameter [TSS3]. Pump the PVC pipe full of grease. Thoroughly clean the open end of the pipe with a solvent, which will remove grease. Then glue another cap with drill hole on the remaining open end. Set aside while continuing with the next step. (*NOTE: This step can also be done in advance, prior to going into the field.)

C. Using a power auger or post hole digger, drill or dig a hole in the ground 12 - 14 inches in diameter




and 43 inches deep.

D. Attach the standard spiral (fluted) rod entry point [SS-12 point] to one end of the 4-foot section of stainless steel rod [SS-916-04] with the standard 3/8-inch stud [M-13 thread] using thread adhesive. On the opposite end, screw on a short 4” piece of rod [M-1 DPA] which will be used as the impact point for driving the rod. Drive this section of rod with a reciprocating driver such as a Pionjar 120, Cobra 148, Wacker BHB 25 or another machine with an equivalent driving force.

E. Remove the short piece of rod used for driving [M1DPA] and screw in a new stud [M13 thread]. Attach another 4-foot section of rod [SS-916-04] using thread adhesive. Tighten securely (*using vise grips or pipe wrenches). Reattach the short piece of rod [M-1DPA] and drive the new section into the ground.

F. Repeat step 6 until the rod refuses to drive further or until a driving rate of 60 seconds per foot is achieved, but not more than 90 feet. The top of the rod should terminate about 5 inches below ground surface. Carefully remove the driver [M1DPA].

G. Insert the grease filled 3-foot section of one inch (1”) PVC pipe sleeve [TSS3] over the rod with the unfilled portion at the top. The rod and datum point should protrude through the sleeve about 3”. The sleeve should be resting at or near the bottom of the hole.

H. Using the existing threaded rod end, install the threaded stud [M13] using thread adhesive. Install the datum point [MSSDP1] using thread adhesive. Tighten ¼ turn past finger tight. The following alternative procedure may be used with the approval of the Engineer. Cut off the top removing the tapped and threaded portion of the rod leaving about 3 inches below ground surface. The top of the rod must be shaped to a smooth rounded (hemispherical) top, using a portable grinding machine to produce a datum point. The datum point must then be center punched to provide a plumbing (centering) point OR use a compression-fit bronze cap center punched.

I. Backfill and pack with fine-grained washed or play sand around the sleeve [TSS3] to about 20 inches below surface. Place the 6” PVC [6PVC24] and logo cap [BMAC] over and around the 1” sleeve [TSS3] and rod. The datum point [SSDP-1] should be about 3 inches below the cover of the logo cap.

J. Continue to backfill and pack with sand inside the 6” PVC [6PVC24] and around the outside of the 1-inch sleeve [TSS3] and rod to about 1 inch below the top of the sleeve.

K. Place concrete around the outside of the 6-inch PVC [6PVC24] and logo cap [BMAC], up to the top of logo cover. Trowel the concrete until a smooth neat finish is produced.

L. Remove all debris and excess dirt to leave area in original condition. Make sure all excess grease is removed and the datum point [SSDP-1] is clean.

M. Install a Carsonite fiberglass witness post 2 to 3 feet adjacent to and behind the installed monument [CBM6004SM110] or approved equal.

101-3.1 – REMOVAL OF EXISTING PAVEMENT

A. Concrete Pavement. The existing concrete pavement to be removed shall be freed from the pavement to remain by sawing through the complete depth of the slab one foot (30 cm) inside the perimeter of the final removal limits or outside the dowels, whichever is greater when the limits of removal are located on the joints. The pavement between the perimeter of the pavement removal and the saw cut shall be carefully broken up and removed using hand-held jackhammers, weighing 30 pounds (14 kg) or less, or other light-duty equipment which will not cause distress in the pavement which is to remain in place. The contractor shall have the option of sawing through the dowels at the joint, removing the pavement and installing new dowels. Where the perimeter of the removal limits is not located on the joint and there are no dowels present, then the perimeter shall be saw cut the full depth of the pavement. The pavement inside the saw cut shall be removed by methods suitable to the Engineer which will not cause distress in the pavement which is to remain in place. If the material is to be wasted on the airport site, it shall be reduced to a maximum size designated by the Engineer. The contractor’s removal operation shall not cause damage to cables, utility ducts, pipelines, or drainage structures under the pavement. Concrete slabs that are damaged by under breaking shall be removed. Any damage shall be repaired at the contractor’s expense.

B. Asphaltic Concrete Pavement. Asphalt concrete pavement to be removed shall be cut to the full depth of the bituminous material around the perimeter of the area to be removed. The pavement shall be removed so the joint for each layer of pavement replacement is offset 1 foot (30 cm) from the joint in the preceding layer. This does not apply if the removed pavement is to be replaced with concrete or soil. If the material is to be wasted on the airport site, it shall be broken to a maximum size of 1 inches.

101-3.2 – PREPARATION OF JOINTS AND CRACKS. Remove all vegetation and debris from cracks to a minimum depth of 1 inch (25 mm). If extensive vegetation exists treat the specific area with a concentrated solution of a water-based herbicide approved by the Engineer. Fill all cracks, ignoring hairline cracks (< 1/4 inch (6 mm) wide) with a crack sealant per ASTM D6690. Wider cracks (over 1.5” wide (38 mm)), along with soft or sunken spots, indicate that the pavement or the pavement base should be repaired or replaced as stated below. Any excess joint or crack sealer on the surface of the pavement shall also be removed from the pavement surface.

A. Cracks and joints may be filled with a mixture of emulsified asphalt and aggregate. The aggregate shall consist of limestone, volcanic ash, sand, or other material that will cure to form a hard substance. The combined gradation shall be as shown in the following table.

PART 1 – GENERAL

1.1 SUMMARY

A. Contractor shall follow the specifications in this Document when excavating and removing contaminated soil, sludge, and water. Known areas and quantities of contaminated material have been identified. When contractor encounters contaminated material which has not been previously identified, contractor shall suspend work in the contaminated area and redeploy forces as necessary to minimize delay or disruption, until the testing has been completed and the soil, sludge, and water to be removed has been identified. If contamination occurs in separate and distinct areas, contractor may continue the Work in other areas of the project site while characterization is carried in newly discovered contamination zones.

B. If underground fuel lines are exposed, contractor shall arrange for Contract Manager to test the soil surrounding the pipe. Contaminated soil and water associated with the pipeline shall be remediated as part of the pipeline abandonment. Fuel lines shall be removed or abandoned as defined in in the contract.

C. Airport may, at its option, use the Airport's "On-Call" contractor to remediate the hazardous materials/waste encountered at the site. Where utilized, the "On-Call" contractor shall mobilize within 48 hours of confirmation testing of the site. The remediation will be conducted in cooperation with contractor to avoid unnecessary interference with the Work. Contractor shall cooperate with the remediation effort and shall give access to the site to the "On-Call” remediation contractor.
