Securing Your Structure Against the Elements

As buildings in Dhaka and industrial zones grow taller, the risk of a direct lightning strike increases exponentially. At Brothers Engineering BD, we provide advanced Lightning Protection Systems (LPS) designed to intercept high-voltage atmospheric discharges and safely channel them into the earth, preventing structural fire, electrocution, and catastrophic equipment failure.

Our Core Lightning Protection Expertise:

• Air Termination Systems (Lightning Rods): Installation of copper or aluminum rods (arrestors) at the highest points of your structure to “catch” the strike.

• Down-Conductor Systems: Precision routing of heavy-duty conductors that carry the current from the roof to the ground without causing “side-flashing” into the building’s internal wiring.

• Earth Termination (Grounding): Low-resistance earth pits using chemical earthing or copper plates to ensure the lightning energy is dissipated instantly into the soil.

• Surge Protection Devices (SPD): Internal protection for your sensitive electronics (computers, servers, HVAC controllers) to block secondary surges traveling through power lines.

• Early Streamer Emission (ESE) Systems: Modern, active arrestors that provide a wider “zone of protection” for large industrial complexes and sports turfs.

Our Design & Installation Process

1. Risk Assessment: We calculate the “Lightning Strike Frequency” for your specific location in Bangladesh to determine the required Protection Level (Class I to IV).

2. Zone of Protection Mapping: Using the “Rolling Sphere” or “Mesh” method, we ensure every corner of your roof, including AC outdoor units and water tanks, is covered.

3. Soil Resistivity Testing: We test your site’s soil to design a grounding system that remains effective even during the dry season.

4. Structural Integration: Our engineers ensure that the installation does not compromise your building’s waterproofing or architectural aesthetic.

The Difference: Lightning Rod vs. Lightning Arrestor

• The Lightning Rod (Air Terminal): Protects the Structure. It sits on the roof and prevents the building from catching fire or cracking.

• The Lightning Arrestor (Surge Diverter): Protects the Electrical System. It is installed near your main switchboard to stop high-voltage spikes from burning out your appliances.

At Brothers Engineering, we provide both to ensure “Total Protection.”

Why Compliance with BNBC 2020 is Mandatory

The latest Bangladesh National Building Code mandates that all high-rise buildings and industrial structures must have a certified lightning protection system. Failure to comply can lead to:

• Legal Liability: Rejection of fire safety certificates or occupancy permits.

• Insurance Rejection: Most modern insurance policies will not cover fire damage caused by lightning if a certified LPS was not present.

Why BNBC 2020 Compliance Matters

Following the Bangladesh National Building Code (BNBC) is not just about safety; it’s about legality. Our consultancy ensures your building is ready for:

• Fire Service (FSCD) Inspections: We provide the technical drawings required for your fire safety certificate.

• Structural Integrity: We ensure the down-conductors are installed without damaging your building’s exterior or causing “side-flashes” into the RCC reinforcement.

• Asset Insurance: Most commercial insurance providers in Bangladesh now require a certified Lightning Protection System to process fire-related claims.

• Advanced Lightning Protection for Bangladesh’s Climate

  In a tropical country like Bangladesh, lightning strikes are a major cause of industrial fires and electrical failure. At Brothers Engineering BD, our consultancy goes beyond simple “lightning rods.” We design an integrated safety shield for your building. Whether you are managing a high-rise in Dhaka or an industrial garment factory in Gazipur, our systems are engineered to handle the high-current discharges typical of our local thunderstorms.

Consultancy & Maintenance Services

A lightning arrestor is not a “set and forget” system. Brothers Engineering BD provides:

• Annual Continuity Testing: Checking if your conductors are still securely connected.

• Earth Resistance Measurement: Using digital earth testers to ensure your ground pits are still functional.

• Retrofit Design: Upgrading old, rusted lightning rods on existing buildings with modern, active ESE (Early Streamer Emission) technology.
