III - Executive Summary

i. Inspection Summary

The 80’ self-supporting communications tower at the U.S. Coast Guard Station Eaton’s Neck in Northport N.Y. was inspected on 13-14 July 2015 by SiteMaster, Inc. of Tulsa, Oklahoma. The lacing of the four tower sections consisted of bolted, x-braced angles from 0-20’, bolted solid diagonals from 20-60’ and welded, solid round diagonals from 60-80’.

ii. Structural Members

The inspectors found no loose anchor bolts on any of the tower legs. All anchor bolts are equipped with pal nuts.

The inspectors did not find any loose structural connection bolts on any of the three tower legs from 0-80’. Inspectors noted that all connection bolts are equipped with pal nuts.

Inspectors found no loose connection bolts on any of the diagonal members or gusset plates. All bolts are equipped with a locking device such as pal nuts.

A variable amount of rust and corrosion is visible on all three tower legs from 20-80’. All surfaces are rusted or corroded.

A large percentage of the connection bolts on the tower flanges and diagonals are also rusted or corroded.

The tower foundation is in satisfactory condition.

There are three bent diagonal members at 61’, 62’, and 79’6”.

iii. Alignment and Twist

A visual inspection of the tower’s alignment showed that the structure appeared plumb.

vii. Insulator Systems

Not applicable to this tower.

viii. Grounding Systems

The tower appears to be satisfactorily grounded. All three tower legs have clamped grounding leads. Each ground lead is running underground to a presumed tower ground ring.

The coaxial cable on the tower is not grounded although grounds are cut in to the coax.

The leads have been removed and no buss bars are installed.

The inspectors suggest the ground leads on the tower legs be exothermically welded to the tower legs to conform to industry standards. It is also suggested that the coax be properly grounded and the ground leads be connected to a buss bar that is connected directly to the ground ring at the bottom of the tower. The coax should also be grounded on the tower before the connection to the antenna and the buss bar should be directly connected to the tower allowing the tower legs to act as the connection to the grounding ring.

There is no lightning rod on the tower. It is suggested a lightning rod be installed at the top of the tower and that it is attached to its own ground lead. The ground lead should run the length of the tower and be exothermically welded to the ground ring at the bottom of the tower.

ix. OSHA Standards

The tower is equipped with a climbing ladder and safety climb rail. The climbing ladder extends from 20-80’ and is mounted directly to the face of the tower. The climbing ladder mounting U-bolts are stainless steel and in good condition. The ladder flanges are rusted and corroded. 100% of the climbing ladder and connections were wire brushed and application of zinc-rich cold galvanizing paint was applied.

The safety climb rail extends from 20-80’. The rail and mounting hardware shows signs of rust and corrosion. 100% of the safety rail and hardware was wire brushed by the inspectors and an application of zinc rich cold galvanizing paint was applied.

It is suggested the climb ladder and the safety rail be extended to the bottom of the tower.

It is also necessary to mount the ladder on standoffs allowing for the 7” OSHA requirement of clearance between the ladder rungs and the tower face.

It is also recommended that the safety climb rail be replaced with a 3/8” safety climb cable device to conform to industry standards.

x. Miscellaneous

The inspectors found two antennas on the tower at separate heights. The first was mounted at 57’6”. The antenna appears to be in good condition, although the mounting hardware shows significant signs of rust and corrosion. The second antenna is mounted at 63’8” and 80’. The antenna shows some signs of aging and requires attention to avoid more costly repairs. The antenna mounting hardware shows signs of corrosion and rust.

All areas of rust and corrosion were wire brushed by the inspectors and an application of cold galvanization was applied.

xi. Maintenance Accomplished

The inspectors used a wire brush and cleaned heavily rusted or corroded components of the tower. 100% of the tower received an application of zinc-rich cold galvanization compound. 100% of bolts were checked for torque and tightened where needed.

IV – Recommendations

Within 1 Year:

1. A six foot lightning rod should be installed at the top of the tower.

2. Coax needs to be properly grounded and the ground leads be connected to a buss bar that is connected directly to the ground ring at the bottom of the tower.

3. It is suggested the climb ladder and the safety rail be extended to the bottom of the tower. It is also necessary to mount the ladder on standoffs allowing for the 7”

OSHA required clearance between the ladder rungs and the tower face.

4. It is recommended that the safety climb rail be replaced with a 3/8” safety climb cable device to conform to industry standards.

5. Tower leg ground leads need to be exothermically welded to the tower legs to comply with industry standards.

6. Replace the three bent diagonal members at 61’, 62’, and 79’6”.
