AMENDMENT#0002 RFI'S

WO# N40080-18-1557713

PROVIDE ADEQUATE GORUND PROTECTION USNA WATER TREATMENT PLANT

RFI – 1 August 27, 2018 – RESPONSE

ITEM 1: The steel housing is currently being used but the resistance to ground is greater than what would be provided by the copper conductors. The tower was constructed in 1966 and it was anecdotally said the original grounding of the tower included a copper down conductor that was removed when the tower was painted but was not reinstalled. This design is based on the recommendations of The Lightning Protection Institute LPI 175-2017. This is a robust design to comply with the mission critical requirements of this tower.

Existing Ground Rod Bonding Exterior of Tower to Earth Typical of Four.

Base on the history and damage of past lightning appear to be inadequate.

Based on the age and construction of tower the steel housing does not provide a continuous low resistance to ground.

ITEM – 2 Agree with comment. Provide required fasteners at a minimum of three (3) feet intervals

ITEM – 3 DRAWING CLARIFICATION:

A. PROVIDE RING GROUND ELECTRODE SYSTEM. THE GROUND ELECTRODE SYSTEM

SHALL BE A MAIN SIZE COPPER LIGHTINING CONDUCTOR. A GROUND RING

ELECTRODE SYSTEM SHALL ENCIRCLE THE STRUCTURE AND SHALL BE IN DIRECT

CONTACT WITH THE EARTH AT A DEPTH OF 18 INCHES (457MM) OR MORE.

B. The down conductor is to be connected to one down rod. The two (2) rod detail is meant show the connection of the ring between the down rods.
