Electrical Design Services | Brothers Engineering BD

Price: 1.02 USD Per SFT (or 0.80 – 1.00 USD) Electrical Design services for residential, commercial, and industrial projects are a core specialty of Brothers Engineering BD.

Deliverables: Lighting & Power Layouts, Conduit Layouts, Load Calculations, Single Line Diagrams (SLD), Earthing & Lightning Protection, and Sub-station/Generator Planning.

Electrical Design Services | Brothers Engineering BD

At Brothers Engineering BD, we treat a building’s electrical system as its critical nervous system. Our Electrical Design services prioritize safety, energy efficiency, and long-term reliability. We move beyond simple wiring to provide scientifically engineered power solutions that eliminate risks like short circuits, voltage fluctuations, and electrical fires. Whether it is a modern smart home or a high-capacity industrial plant, we ensure your electrical infrastructure is robust, scalable, and fully code-compliant.

Our Core Electrical Expertise:

• Lighting & Power Layout Design: Precision placement of switchboards, sockets, and lighting fixtures for optimal convenience, aesthetics, and energy savings.

• Load Calculation & Balancing: Expert analysis of peak demand to determine the exact requirements for cables, circuit breakers, transformers, and generators.

• Earthing & Lightning Protection Systems: Specialized safety designs, including copper-plate earthing and lightning arrestors, to protect residents and sensitive electronics from surges.

• Single Line Diagrams (SLD): Creating technical blueprints for Main Distribution Boards (MDB) and Sub-Distribution Boards (SDB) to ensure easy maintenance and troubleshooting.

• Conduit & Circuit Mapping: Intelligent routing of electrical pipes to avoid interference with structural beams and plumbing lines, reducing material waste.

Our Electrical Design Process

To deliver safe and high-performance results, our workflow follows these rigorous engineering phases:

1. Total Connected Load Analysis: We calculate the total wattage requirements for all appliances, HVAC systems, and machinery to prevent system overloads.

2. System Schematic Modeling: Using advanced software to simulate power flow and voltage drop, ensuring consistent electricity delivery to every corner of the building.

3. Safety & Protection Coordination: Selecting the correct ratings for MCBs, MCCBs, and RCCBs to ensure the power cuts off instantly during a fault.

4. Technical Drafting & Detailing: Producing high-detail “Electrical Working Drawings” including legend sheets, circuit numbers, and wire gauge specifications.

5. BNBC & International Compliance: Ensuring all designs strictly follow the Bangladesh National Building Code (BNBC) and IEEE safety standards.

Why Professional Electrical Design is Essential

The primary goal of professional Electrical Design Services is life safety. In Bangladesh, many building accidents are caused by “guesswork” electrical installations. Our engineers use precise mathematical modeling to ensure that every wire gauge and breaker size is perfectly matched to the load, preventing overheating and fire hazards.

Furthermore, our designs prioritize operational cost-efficiency. By optimizing the power factor and balancing phases, our designs reduce energy loss and help lower your monthly electricity bills. With our detailed blueprints, your electricians have an exact roadmap, eliminating expensive errors and ensuring the building’s safety for generations.

Specialized Electrical Categories

• Residential Smart Homes: Integrated wiring for home automation, security cameras, and luxury lighting control.

• Industrial & Garments Factories: High-voltage planning for heavy machinery, busbar trunking systems (BBT), and industrial lighting.

• Commercial Offices & Showrooms: Strategic power layouts for server rooms, workstations, and high-impact display lighting.

• Power Infrastructure: Specialized design for building sub-stations, solar power integration, and emergency generator synchronization.

Comprehensive Site Supervision

Beyond the initial technical drawings, our Electrical Design services include expert site inspections. We verify the quality of cables (BRB, Paradise, etc.), check conduit placement before casting, and conduct insulation resistance tests before the system is energized. This rigorous supervision ensures your investment is protected by scientific rigor and engineering excellence.

Frequently Asked Questions (FAQ)

• What is included in the 90 BDT/SFT price? This covers the full electrical design set: lighting/power layouts, SLD, load calculations, earthing plans, and periodic site visits.

• Do you design for Solar Power? Yes, we provide hybrid electrical designs that integrate solar panels with the main grid to reduce utility costs.

• Can you fix electricity problems in an existing building? Absolutely. We offer “Electrical Safety Audits” and retrofitting services to upgrade old wiring to modern safety standards.
