A practical starting point

Planning your Tennessee project

Check the project type before choosing a permit route

Tennessee’s State Fire Marshal publishes residential-permit guidance and a separate list of exempt jurisdictions for commercial-building review. Its residential page links to the locations served by the state program and the CORE online system.

Identify whether the proposal is residential or commercial, then confirm the relevant state or local application route for the address. Provide that office’s checklist and written comments with your engineering request. A residential-directory entry does not establish the review route for a different building type.

Define the work

Building systems, planned together.

Lightning Engineering provides mechanical, electrical and plumbing engineering for buildings with different uses and operating needs. We develop the engineering scope around the project plans, building systems and information provided by your team.

01

Mechanical engineering

HVAC system design and load calculations support heating, cooling and ventilation planning. Our team considers the building’s use, layout and mechanical requirements as part of the design.

02

Electrical engineering

Electrical plans address the power and lighting systems included in your project. Coordinate equipment information and the proposed layout with our team at the start of the design process.

03

Plumbing engineering

Plumbing design coordinates water supply, drainage and the systems required for the building. Existing conditions and the proposed fixture or equipment layout help define the work.

Make the request easier to review

What to send for MEP engineering

Share the available documents together, and identify anything still being prepared by another member of the project team.

Project address, building use and approximate size
Current architectural plans and available existing drawings
Equipment schedules and known utility or system requirements
Permit comments, project contacts and target schedule

Choose the right starting point

New plans, an existing structure, or review comments?

Planning new work

Send the intended use, available survey, preliminary layout and scope requested by the owner or designer. Identify documents being developed by the manufacturer, architect or other consultants.

Changing existing work

Include existing plans, photographs and available permit records. Describe what is changing and what will remain. Note any information about the existing structure that has not yet been confirmed.

Responding to comments

Send the complete comment letter and the exact plan version reviewed. Identify previous responses and changes requested since that review so the disciplines can be coordinated.

Before you begin

Common project questions

Use the project’s actual records and agency requests to establish the engineering scope.

What does MEP stand for?

MEP stands for mechanical, electrical and plumbing. These disciplines address the building systems that support comfort, power, lighting, water supply and drainage.

Do you work on both new buildings and renovations?

Yes. We provide MEP engineering for new construction and renovation projects. The work needed is reviewed against the existing systems and proposed changes.

Can energy calculations be included?

Yes. Energy calculations and COMCheck services are available. Tell us what your project and reviewing jurisdiction require so the proposal can identify the appropriate deliverables.
