1 Project Procedure LIGHTNING PROTECTION 07/21/2011 PAGE 1 OF PURPOSE The purpose of this procedure is to ensure that lightning protection installations are accomplished in compliance with Project specifications, engineering and design drawings, applicable codes, and Contract requirements. 2.0 SCOPE The scope of this procedure applies to Pike activities. This procedure may also be applied to Subcontractors when invoked by Contract documents. 3.0 REFERENCES 3.1 Project Procedure P-1-4, Quality Control Functions and Responsibilities (Construction Site) 3.2 Project Procedure P-1-5, Quality Control Personnel Assignments (Construction Site) 3.3 Project Procedure P-1-9, Quality Control Interface with Subcontractors 3.4 Underground Electrical Project Procedure P-6.2-1, Direct Buried Cable Project Procedure P-6.2-2, Ductbank Installations Project Procedure P-6.2-3, Grounding Below Grade 3.5 Aboveground Electrical Project Procedure P-6.2-4, Electrical/Instrumentation Raceway and Cable Installation Project Procedure P-6.2-5, Power Transformer Installation 3.6 National Fire Protection Association (NFPA) NFPA 780, Standard for the Installation of Lightning Protection Systems 4.0 DEFINITIONS 4.1 Independent Testing Organization (ITO): Any group, other than construction personnel, who perform and document required electrical testing.

2 PAGE 2 OF RESPONSIBILITIES 5.1 The Construction Site Supervisor is responsible for the following: Resolution of lightning protection installation and test issues with the Project Engineering organization Retention of required documentation in the Job Site Files 5.2 Other personnel responsibilities are as defined in the procedures Quality Control Functions and Responsibilities (Reference 3.1) and Quality Control Personnel Assignments (Reference 3.2). 6.0 PROCEDURE 6.1 PREREQUISITES Understanding the Requirements Prior to the start of lightning protection installation activities, requirements for inspections and testing (including associated documentation) shall be established and agreed upon in accordance with the Quality Control Interface with Subcontractors procedure (Reference 3.3). The ITO relationship must be established and Client contacts defined. The Construction Site Supervisor or the Site Quality Control Manager shall coordinate this activity Subcontracted Work Prior to the award of a Subcontract, the Construction Site Supervisor and Site Quality Control Manager shall review the applicable engineering documents to determine the extent of installation and testing work to be subcontracted. This review shall include either selection of the applicable sections of the Quality Control Project Procedures for the Scope of Work for each Subcontract or review and acceptance of the Subcontractor s quality system program for control of the work. See the Quality Control Project Procedures for Underground Electric Construction (see Reference section 3.4) for more details. 6.2 GENERAL The Construction Foreman or Supervisor or designee, in coordination with the Site Quality Control Manager or Construction Site Supervisor, shall verify completion and compliance of lightning protection installation and testing activities and indicate acceptance of the work via signature on Form QF A, Lightning Protection (see

3 PAGE 3 OF 5 Form 8.1). ITO forms shall be signed-off as appropriate to indicate acceptance of ITO activities. 6.3 INSPECTION AND VERIFICATION The Site Quality Control Manager or qualified designee shall assure the following meet the requirements of Project drawings and specifications: Verify lightning protection materials and components meet the requirements of the engineering design for weight, size and composition. Verify materials in accordance with the design drawings and specifications. Aluminum components may be used where mounted to aluminum surfaces to avoid galvanic corrosion. Confirm correct classes of materials are used as appropriate for height of structure (Class I or Class 11). Verify that air terminals (also called lightning rods) and mounting bases of the correct type are provided. Verify that air terminals project the required distance above the object to be lightning-protected. Verify that air terminals are placed in sufficient numbers and at correct intervals in accordance with the engineering design. Verify that copper or aluminum down ground conductors of the correct size interconnect all air terminals. Verify that a two-way path to the ground is provided from all air terminals. Verify that the downward path to the ground is free of splices and sharp bends. Verify that fasteners of the correct type are placed on each run of exposed conductor at the required intervals. Verify that down conductors of the correct size are placed at prescribed intervals around the perimeter of the protected structure. For steel framed buildings, verify roof conductors are connected to the building frame at prescribed interval. Down conductors may be omitted. Verify connection to the steel frame of the building is made with bonding plates of the correct size and area of contact. Verify common grounding of all grounding mediums within the building or structure.

4 PAGE 4 OF 5 Verify each down lead is terminated in a ground connection in accordance with the engineering and design. Verify that surge arrestors and suppressors are installed to protect electronic equipment and systems as required by the engineering and design. Verify Supplier hold/inspection points are identified and completed. Verify that certification documentation is received and available. 6.4 LIGHTNING PROTECTION SYSTEM CERTIFICATION The Construction Site Supervisor or Site Quality Control Manager shall confirm certification of the lightning protection system in accordance with the engineering and design. 6.5 SUBCONTRACTED WORK During lightning protection installation and testing activities, the Construction Site Supervisor or designee shall monitor and verify the Subcontractor s work for compliance with engineering requirements and applicable procedures. As a minimum, this shall include the following: When Subcontractors are working to the Quality Control Project Procedures, compliance shall be maintained to the applicable sections of these procedures, as required by the Contract. When Subcontractors implement their own program for control of the work, the Site Quality Control Manager or designee shall verify compliance with that program. Installation, verification, and testing activities shall be documented in accordance with Pike s Quality Program or the Subcontractor s own program for control of the work as required by Contract. 6.6 IMPLEMENTATION OF PROGRAM The Site Quality Control Manager shall assure the implementation of this program is consistent with the engineering and design and the Contract. 7.0 ATTACHMENTS None
