Integration of electrical systems with other design disciplines—namely mechanical, architectural, interior design (ID), and structural—is essential to developing a coordinated, constructible, and code-compliant building design. Electrical components and installations are physically embedded within the building fabric and share space with other systems. Therefore, effective coordination is necessary from the early design stages to avoid spatial conflicts, enhance functionality, and meet regulatory and operational requirements.

From the mechanical perspective, coordination is needed to supply power to HVAC systems, pumps, fans, motor control centers, and building management systems. Electrical raceways must be carefully routed in ceilings, risers, and corridors to avoid clashes with ducts, chilled water pipes, and sprinkler networks. Mechanical rooms must accommodate electrical panels, control wiring, and emergency shutdown systems without compromising maintenance access or airflow requirements.

Architectural coordination involves aligning electrical panel locations, lighting fixture positions, and device placements with wall layouts, ceiling types, and fire-rated partitions. Ceiling void congestion, fixture mounting surfaces, and visual aesthetics must be considered when planning electrical containment and device locations.

Interior design integration is vital for the selection and placement of visible electrical elements such as light switches, sockets, decorative lighting, and control panels. The electrical design must accommodate the interior designer’s vision for finishes, materials, lighting scenes, and furniture layouts, while maintaining accessibility and compliance with installation standards.

Structural coordination ensures that cable trays, conduits, busways, and recessed boxes do not interfere with beams, slabs, or columns. Penetrations through structural elements must be minimized and clearly documented. Floor box and core opening locations must be planned in alignment with the structural grid and approved by the structural engineer.
