MEP Engineering & Design
Electrical Design
Building power distribution, lighting, service sizing, and equipment connections coordinated with the complete MEP design.
Overview
Electrical design turns the building’s load requirements into an organized system of service equipment, distribution, lighting, and branch circuits. TPS coordinates those systems with mechanical and plumbing equipment and the owner’s operations. When the project includes standby power, EV charging, or a major service change, we connect the design to the appropriate specialty engineering and power-system studies.

Methodology
How the engagement runs
We agree on inputs, responsibilities, and deliverables before the work begins, then keep the design decisions connected through each stage.
Electrical Design: how the engagement runs
- 1Establish loads and service constraintsCollect building loads, mechanical equipment selections, existing service information, and available utility data. Identify capacity questions early.
- 2Develop the distribution designPlan service equipment, panels, feeders, lighting, and branch circuits around the building layout and operating requirements.
- 3Coordinate equipment and analysisReconcile mechanical and plumbing equipment connections with the electrical schedules. Define any short-circuit, coordination, arc-flash, or load-flow study scope.
- 4Document for the project stageIssue coordinated electrical drawings, schedules, and specifications, with utility and construction support as agreed.

FAQ
Common questions
What is the difference between electrical design and a power system study?+
Electrical design defines what to build: equipment, layouts, circuits, schedules, and specifications. A power-system study evaluates how that system performs. TPS offers both and can align the analysis with the design when the project needs it.
Can TPS coordinate power for new HVAC equipment?+
Yes. Equipment connections, electrical loads, and service capacity are part of the coordination between mechanical and electrical design. Send the equipment schedule and available existing electrical drawings to start the review.
Does TPS design emergency power and EV charging?+
Yes. Those capabilities have their own detailed service pages. We can include them in the building design or scope them as a focused assignment, including utility coordination and supporting studies as needed.
