2 General Information The 134' free standing skeletal tower is located on the west bank of the Delaware River about

9.6 miles southeast of Middletown. See Table 2: Geographic Information for further location information. The tower construction consists of a skeletal steel tower comprised mostly of pipe and solid round bars supporting a center shaft with spiral staircase leading to a lighthouse cab at the top.

3 Inspection and Maintenance Summary

The 134' free standing skeletal tower, Reedy Island Rear Range Light, was partially inspected on May 9, 2013 by Mark Cantrell and Jody O’Neal. The inspectors returned with a man lift on June 1, 2013 to inspect the skeletal structure. For the first visit, the weather was partly cloudy, temperature was 68º with average wind speeds of 10 mph. For the second visit, the weather was sunny, temperature was 85º with average wind speeds of 12 mph. Our POC for this site was Sean Hayes (215-271-4847).

This report follows the Coast Guard Tower Manual naming convention for the tower leg and face designations. The figure below further defines how the tower legs and face are identified.

Location Map Plot Plan

3.1 Structural

The base shoe at Pier C was cracked as shown in Photos No. 16 and 17. This is one of six similar parts securing the tower to the foundations. The break extends approximately one third of the circumference, significantly compromising the uplift resistance and endangering the tower under significant wind load events. The material appears to be either cast steel or cast iron but before repairs can be affected, we recommended removing a “coupon” and having it tested. Once the material type is known, a weld repair can be designed and implemented. This process should begin immediately.

One short bolt in section two was noted by the inspectors (Photos No. 38 and 39) and it should be replaced within one year.

3.1.1 Foundation and Members

(918) 683-8915

All six of the foundation piers show some level of minor cracking and efflorescence (Photos No.

2, 4, 5, 6, 7, 8, 10, 11, 12, 13, 14). We recommend repair by first waster blasting to remove all loose material and calcium deposits, followed by patching of the cracks and application of a sealer to the entire exposed foundation piers. Grout was cracked and loose in several areas (Photos No. 3 and 9). The loose grout should be removed and replaced with new grout. These repairs should be accomplished within two years.

3.1.2 Coating

The interior and exterior paint coating was virtually gone, offering very little protection to the tower (Photos Number 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 33, 34, 36, 37, 40, 41, 44, 45, 46, 47, 48, 49, 54, 56, 60, 61 and 69). Corrosion and peeling paint were the norm throughout. Complete repainting within one year is recommended both for the exterior members and the center shaft (inside and out).

3.2 Navigational Aids

This tower supports a lantern. Electrical cable to power the light was inadequately supported (Photos Number 46, 47 and 48). Proper support should be added within one year.

3.3 Grounding

Only one exterior ground was noted on this structure (Photo No. 14). We recommend upgrading the grounding system to the ANSI-TIA-222-G standard using 2/0 stranded tinned copper wire connected to six ground rods placed symmetrically around the base of the tower1. A minimum of one lead should be connected to each tower leg. Connections to the ground rods should be made with exothermic welds. This should be accomplished in one year.

3.4 OSHA Standards

There was extensive corrosion throughout the handrails around the platforms and they should be completely replaced with new rails designed to meet OSHA standards (include toeboards) (Photos Number 57, 64, 66 and 68).

The top platform was not 24” wide throughout as required by OSHA standards (Photo No. 64), however, modification to widen the platforms would be impractical and of questionable value.

Four bolts were protruding from the top platform walkway creating a tripping hazard (Photos No. 64 and 67) and they should be removed.

3.5 Maintenance Accomplished

The inspectors removed some loose rust in certain areas during the inspection. These disturbed areas were then coated with cold galvanizing compound (Photos Number 22, 23, 26, 27, 28 and 29).

1 American National Standard Institute, ANSI/EIA/TIA-222-G-2005: Structural Standards for Antenna Supporting Structures and Antennas: 2005 (Arlington, VA: TIA Standards and Technology Department, 2005) §10.5 and A10.0.

(918) 683-8915

3.6 Miscellaneous

Birds were entering the center shaft and many dead birds were noted during the inspection. To help prevent this problem, a damaged window vent (Photos No. 32, 52 and 53) should be replaced within one year.

The center shaft entrance door was severely corroded (Photos Number 42 and 43) and should be replaced within one year.

Water was entering the center shaft around inadequately sealed plexiglass (Photos Number 50, 51, 52, 53 and 58). These areas should be sealed within one year.

Tree limbs were interfering with the incoming power line (Photos No. 18 and 19) and should be trimmed back within two years.

Two unused antenna pipe mounts were noted attached to the top platforms (Photos No. 62 and 63) and they should be removed within two years.

(918) 683-8915

4 Recommended Maintenance The cracked base shoe member (Photos No. 16 and 17) is a very serious structural concern and it should be addressed immediately. The uplift resistance of the tower has been compromised and complete failure of this member would significantly increase the potential of the tower toppling over under extreme wind load conditions.

OSHA STANDARDS: This tower does not fully comply with OSHA standards. The items required to upgrade the tower for compliance are outlined below. This requirement has no effect on the tower structure or its function. Deferral of OSHA upgrades is not recommended. However, cost estimates for this work assume it will be accomplished within two years.

Estimates are based on fully burdened prevailing wage rates. Labor rates for work to be accomplished within one year have been escalated 5%, 10% for two years, and 15% for three years. Equipment costs are included in these rates unless specified.

IMMEDIATELY:

1) Cut a “coupon” from the cracked base shoe member. Analyze the sample to determine the type of material and then develop and affect an appropriate weld repair (Photos Number 16 and 17).

WITHIN ONE YEAR:

1) Repaint the tower and the center shaft inside and out (Photos Number 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 33, 34, 36, 37, 40, 41, 44, 45, 46, 47, 48, 49, 54, 56, 60, 61 and 69).

2) Replace the window vent for the 6th window (Photos Number 32, 52 and 53).

3) Replace the short structural bolt with proper size bolts (Photos Number 38 and 39).

4) Replace center shaft entrance door (Photos Number 42 and 43).

5) Install proper clamps to secure electrical cable running up the spiral staircase (Photos

Number 46, 47 and 48).

6) Caulk all Plexiglas windows to prevent water from entering (Photos Number 50, 51, 52, 53 and 58).

WITHIN TWO YEARS:

1) Clean the foundations by water blasting, seal all cracks with an epoxy concrete patch followed by application of a sealant to the entire foundation (Photos Number 2, 4, 5, 6, 7, 8, 10, 11, 12, 13 and 14).

2) Remove all loose grout and replace with new grout (Photos Number 3 and 9).

3) Upgrade grounding to ANSI-TIA-222-G standard (Photo Number 14).

4) Trim the tree that has grown into the path of the power line (Photos Number 18 and

19).

5) Remove unused antenna pipes on both platforms (Photos Number 62 and 63).

OSHA STANDARDS:

6) Replace all handrail with OSHA standard railing (Photos Number 57, 64, 66 and 68).

7) Remove ½” anchor bolts from the top platform pathway (Photos Number 64 and 67).

APPENDIX C:

ATON TOWER ASSESSMENT STANDARD2

GOOD No problems or only minor problems noted. Structure elements may show very minor deterioration. Structure fully functional.

SATISFACTORY Minor to moderate defects and deterioration observed. Structure fully functional.

FAIR All primary structural elements are sound, but minor to moderate defects and deterioration observed. Localized areas of moderate to advanced deterioration may be present but do not significantly reduce the function of the structure.

POOR Advanced deterioration observed on widespread portions of the structure.

Movement of the structure has compromised the function of the aid. Unit should photograph and submit an SSMR.

CRITICAL Very advanced deterioration or breakage has resulted in localized failures of primary structural components. More widespread failures are possible or likely to occur. Unit should photograph and submit an SSMR, and initiate a CASREP if necessary.
