PART 3 - EXECUTION

3.1 INSTALLATION OF LIGHTNING PROTECTION SYSTEMS

A. Install lightning protection systems as indicated, in accordance with equipment manufacturer’s written instructions, and in compliance with applicable installation standards specified above.

B. Install conductors with direct paths from air terminals to ground connections avoiding sharp bends and narrow loops. Where indicated, run conductors in non-metallic raceway, type RGE, Schedule 40, minimum.

C. Conceal down conductors.

D. Conceal interior wiring.

E. Conceal wiring from normal view from all exterior locations at grade within 200 feet of building.

F. Splices and Clamps: Use approved exothermic welded connections for all conductor splices and all connections between conductors and other components.

3.2 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.

3.3 GROUNDING AND BONDING

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

3.4 FIELD QUALITY CONTROL

A. Perform inspections of the lightning protection system installation in accordance with LPI-177, “Inspection Guide for LPI Certified Systems”.

Provide Architect with one copy of LPI-177 and retain one copy at the project site throughout construction for reference.

B. Document inspections on LPI forms LPI-C1-02 and LPI Form 1-R88.

Provide one copy of each completed form to the Architect.
