LIGHTNING PROTECTION SYSTEM 264113.00 - 1

SECTION 264113 - LIGHTNING PROTECTION

PART 1 - GENERAL

1.1 DESCRIPTION

A. Description of Systems:

1. A Lightning Protection System shall be placed on the structure by experienced installers in compliance with provisions of Code for Lightning Protection Systems as adopted by the National Fire Protection Association and Underwriters' Laboratories. Intent of the lightning protection systems shall be to protect the new building against damage by lightning. All equipment to that result shall be included whether or not specifically called for herein. Installers shall be LPI (Lightning Protection Institute) certified, master and Journeyman in accordance with LPI Standards or of equal qualifications as approved by the Owner or the Owner’s authorized representative. A U.L. Master Label for the system and a witness of grounding form, similar to that required by LPI (Form 175-A), shall be required.

2. Materials shall comply in weight, size, and composition with the requirements of

Underwriters' Laboratories and the National Fire Protection Code relating to this type of installation, and shall be U.L. Labeled.

3. Contractor shall be required to pull a permit for their work and provide a complete package of permit, drawings, specifications, and details for a complete turnkey system, including but not limited to:

a. Air terminals

b. Bonding plates

c. Conductors

d. Connectors

e. Fasteners

f. Grounding plates

g. Grounding rods

h. Rod clamps

i. Splicers

j. Fittings

k. Test wells.

1.2 SUBMITTALS

A. Shop Drawings and Product Data:

1. Shop Drawings: Shop drawings shall be submitted for approval before any work is started. Drawings shall include full “to scale” layout of cabling and air terminal points, and connections.

2. Product Data: Product Data shall be submitted on all equipment to show compliance with this section of the specifications and shall include manufacturer’s written recommendations for installation. Information shall be submitted for approval before any work is started.

PART 2 - PRODUCTS AND INSTALLATION

2.1 AIR TERMINALS

A. Air Terminals shall be solid aluminum; to be coordinated with the building flashing materials;

and shall have proper base support for surface on which they are attached and shall be securely anchored to this surface. Terminals shall project a minimum of 12" above top of object to which attached.

2.2 CONDUCTORS

A. Roof conductors shall consist of aluminum; to be coordinated with the building flashing materials, complying with the weight and construction requirements of the Code, and shall be coursed to interconnect with air terminals, and in general, provide a two-way minimum path to ground. The angle of any turn shall not exceed 90 degrees and shall provide an approximately horizontal or downward course. Down conductors shall be copper and shall be installed in concealed PVC conduit and concealed within the structure. Approved bi-metal transitions from aluminum roof conductors to copper down conductors shall be provided where aluminum building flashing is used.

2.3 FASTENERS

A. Conductor fasteners shall be of the same material as the conductor, having ample strength to support conductor. Where fasteners are to be mounted in masonry or structural work, they shall be furnished to the Masonry or Structural Contractor so they may be installed during construction of the project.

2.4 GROUND CONNECTIONS

A. Ground connections shall be made in accordance with requirements of all applicable codes.

Ground rods shall be placed in a minimum of two (2) feet from building foundations. In addition to the above requirements additional grounds, one down conductor of each two-path system shall be connected to metallic water piping system with approved water pipe type strap connector. All ground rods shall be a minimum of 5/8" X 50'0” long (sectional) copper-weld type.

B. Provide equipment grounding and bonding connections sufficiently tight to assure permanent and effective grounds and bonds.

C. Grounded metal bodies within the bonding distance determined by the bonding distance requirements of NFPA shall be bonded to the system using bonding conductors and fittings in accordance with code requirements.

D. Underground metallic piping entering the building shall be bonded to the nearest down conductor or ground electrode.

E. Bond to metallic water service, underground metallic piping systems and the building electrical grounding electrode system as shown and as required by codes.

LIGHTNING PROTECTION SYSTEM 264113.00 - 3

F. Bond to metal bodies of conductance on roof with main size conductors as shown and as required by codes. These bonds include, but are not limited to, exhaust fans and stacks, vents, handrails, ladders, conduits, exhaust fans, HVAC / RTU units, antennas, roof mounted lighting standards, etc. or any large metal body subject to direct stroke or which exceeds the height of adjacent air terminals.

G. Bond to metal bodies of inductance located within 6’-0” of main conductor or other bonded object with approved secondary bonding conductor as shown and as required by codes. Such objects include, but are not limited to; flashing, metal coping caps, gravel guards, fascias, roof drains, downspouts, interior ducts, exhaust fans, lighting fixtures, HVAC units, boxes, conduits, boxes, machinery, or piping, etc., or in general, any isolated body at or below the roof subject to inductance and within 6’-0” of the system.

2.5 INSTALLATION

A. Installation shall be made in an inconspicuous manner with conductors coursed to conceal equipment as much as possible. Down conductors shall be concealed within the structure and shall be run in 1" PVC concealed conduit. All metallic equipment within 6 feet of any lightning conductor shall be bonded to conductor. System shall also be tied to the main service electrical grounding electrode conductor system.

2.6 EQUIPMENT

A. Equipment shall be as manufactured by Thompson Lightning Protection, Inc. as specified; or approved substitutions as manufactured by: Independent Protection Company, Inc., Heary Bros.

Lightning Protection or Harger (premium lines).

2.7 CORROSION PROTECTION

A. Use no combination of materials that may form an electrolytic couple of such nature that corrosion is accelerated in the presence of moisture unless moisture is permanently excluded from the junction of such metals. Where unusual conditions exist that would cause deterioration or corrosion of conductors, use conductors with suitable protective coatings.

2.8 FIELD QUALITY CONTROL

A Provide advance notice of at least 24 hours to the Owner’s Authorized Representative before concealing lightning protection system work.

B. Location of all devices and equipment shall be coordinated with all trade contractors and shop drawings prior to submittal of shop drawings.

C. Coordinate installation with other trades to avoid conflicts.

D. During construction, inspection and testing shall be made to assure a low resistance path throughout the system. Upon completion, the air terminals shall be tested for resistance to the grounding electrode system. Any air terminal which has more than 5 ohms resistance to ground shall be connected by additional approved means to reduce the resistance to 5 ohms or less.
