• Electrical Design: Plans the building's electrical systems, including lighting, power distribution, security systems (fire alarms, CCTV), and energy alternatives and backups.

• Mechanical Design: Focuses on HVAC (heating, ventilation, air conditioning), plumbing systems, and air management for comfort and energy efficiency.

• Civil Design: Designs structural elements of buildings like foundations, columns, beams, and outdoor infrastructure such as drainage, roads, and bridges, ensuring strength and stability.

All these designs work together to create safe, efficient, and comfortable buildings.
