What a complete permit package may need.

A permit is rarely just a drawing. Structure, life safety, zoning, mechanical systems, electrical service and plumbing can all shape what the municipality needs to review.

Kernel brings those requirements into a coordinated direction so the package is clear before it reaches the plans examiner.

Selected permit projects.

Examples of the drawings, site conditions and engineering decisions involved in different project types.

Revit isometric showing existing and proposed residential addition levels
Architectural coordinationA three-dimensional model clarifies existing and proposed construction before permit drawings are issued.
Engineered timber beam and framing reinforcement around a new opening
Structural alterationOpenings and changed load paths require buildable framing, connection and support details.
Aerial overview of a commercial roof, mechanical equipment and surrounding site
Commercial and change of useThe permit scope can connect occupancy, life safety, roof equipment and building services.

How permit work moves forward.

The exact deliverables depend on the project and municipality, but the direction stays disciplined from start to finish.

01

Project definition

Property information, intended work and municipal requirements are confirmed.

02

Site review

Existing conditions are measured, photographed and assessed in context.

03

Coordinated design

Structural, architectural and building-system requirements are resolved together.

04

Permit drawings

The submission set is prepared with the required design information and schedules.

05

Municipal review

Plans-examiner comments are tracked and addressed with the project team.

06

Construction support

Clarifications and engineering review continue where the approved scope requires them.

Numbered underpinning excavations documenting a staged foundation sequence

Structural design begins with the existing load path.

Openings, additions, underpinning, new levels and equipment loads begin with an accurate understanding of the existing structure.

What a permit package can include.

The written proposal identifies the exact disciplines and deliverables required for the project. A coordinated package commonly includes the following.

01

Existing conditions

Site measurements, available records and drawings that establish the building before the proposed work.

02

Architectural drawings

Site or floor plans, elevations, sections, layouts, assemblies and schedules needed to describe the intended work.

03

Structural design

Foundation, framing, member, connection and alteration drawings supported by the calculations required for the scope.

04

Building systems

Mechanical, electrical and plumbing drawings, equipment information and schedules where those disciplines are triggered.

05

Code and zoning information

Applicable zoning, occupancy, life-safety, energy and Ontario Building Code information coordinated into the submission.

06

Review support

Responses and revised drawings for municipal comments that relate to the agreed design scope.
