Service Overview

Our Lightning Protection System design service provides engineering assessment, calculation, layout preparation, and technical documentation for industrial and commercial facilities. The design considers the building configuration, roof arrangement, structure height, exposed areas, electrical systems, grounding arrangements, and other relevant site conditions to develop an appropriate lightning protection system.

The service can support new construction, existing factory improvement, building expansion, replacement or modification of existing LPS arrangements, and technical compliance review.

Scope of Service

• Review of building and facility layout
• Assessment of existing Lightning Protection System where applicable
• Air termination system design
• Lightning protection coverage assessment
• Down conductor arrangement and routing
• Earth termination system planning
• Bonding arrangement consideration
• Lightning protection layout drawing preparation
• Integration with building and electrical earthing arrangements where applicable
• Technical recommendations for installation and improvement

Air Termination System Design

Air termination components are positioned to intercept lightning strikes before they directly affect vulnerable parts of the structure. The arrangement is developed according to the applicable design method, building geometry, exposed areas, roof configuration, and technical requirements.

• Air terminal positioning
• Roof conductor arrangement
• Protection of exposed roof-level structures and equipment
• Protection coverage evaluation
• Interconnection of air termination components

Down Conductor Design

Down conductors provide designated paths for lightning current from the air termination system toward the earth termination network. Their quantity, location, routing, mechanical protection, and interconnection are considered during the design to provide an effective lightning-current path.

• Down conductor location planning
• Conductor routing
• Connection with air termination network
• Connection with earth termination system
• Test point arrangement where applicable

Earth Termination and Bonding

The earth termination arrangement provides a path for lightning current to be dispersed into the ground. The design considers the proposed or existing grounding network and coordination with the overall facility earthing system. Appropriate bonding is also considered to help reduce hazardous potential differences during lightning events.

• Lightning protection earth pit arrangement
• Earth electrode layout consideration
• Connection between down conductors and earth termination system
• Bonding of relevant metallic systems where applicable
• Coordination with the existing electrical grounding system

Design Considerations

• Building height and dimensions
• Roof geometry and structure
• Exposed rooftop installations and equipment
• Existing Lightning Protection System
• Number and arrangement of down conductors
• Earth termination arrangement
• Existing building earthing network
• Metallic services and bonding requirements
• Accessibility for inspection, testing, and maintenance

Applicable Standards and Guidelines

Service Deliverables
