- Hydronic piping systems
- Equipment selection and scheduling
- Energy performance documentation
- Coordination with architectural and structural drawings
HVAC Design
Efficient, code-compliant HVAC systems engineered for Ontario's climate.
Our HVAC design services encompass full system design from load calculations through final drawing production. We engineer systems that perform reliably, meet energy efficiency requirements, and are constructible within project constraints.
Scope of Services
- Heating and cooling load calculations
- System type selection and justification
- Ductwork and piping layout
- Equipment sizing and specifications
- ASHRAE 90.1 and OBC energy compliance
- Commissioning support documentation
Plumbing Engineering
Domestic, sanitary, and storm systems designed to OBC standards.
NPS designs complete plumbing systems for new construction and renovation projects. Our drawings are prepared to Ontario Building Code standards and are coordinated with mechanical and structural systems to support efficient construction.
Scope of Services
- Domestic cold and hot water distribution
- Sanitary drainage and venting
- Storm drainage systems
- Fixture unit calculations
- Backflow prevention design
- Specialty plumbing systems
Electrical Engineering
Power, lighting, and low-voltage systems for all occupancy types.
Our electrical engineering services cover power distribution, lighting design, emergency systems, and low-voltage infrastructure. Designs are prepared in accordance with the Ontario Electrical Safety Code and applicable standards.
Scope of Services
- Power distribution and panel schedules
- Lighting design and photometric calculations
- Emergency and exit lighting systems
- Low-voltage and data infrastructure
- Load calculations and service sizing
Fire Protection
Sprinkler and suppression system design to NFPA and Ontario Fire Code.
NPS designs fire protection systems that meet NFPA standards and Ontario Fire Code requirements. Our designs are coordinated with architectural, mechanical, and structural drawings to ensure constructibility and code compliance.
Scope of Services

- Special hazard suppression systems
- Fire alarm system design coordination
- Hydraulic calculations
- Hose cabinet and standpipe design
- Authority Having Jurisdiction (AHJ) submission support
Building Permit Drawings
Complete, coordinated drawing packages ready for municipal submission.
NPS prepares complete building permit drawing packages for submission to Ontario municipalities. Our permit drawings are accurate, fully coordinated across disciplines, and prepared to meet the requirements of the applicable authority having jurisdiction.
Scope of Services
- Mechanical permit drawings
- Plumbing permit drawings
- Electrical permit drawings
- Fire protection permit drawings
- Multi-discipline coordinated packages
- Revision and resubmission support
Our Process
Project Intake
We review your project scope, drawings, and requirements to understand what is needed and confirm the applicable codes and standards.
Engineering Design
Our team develops the engineering design, performs required calculations, and produces coordinated drawings across all required disciplines.
Drawing Production
Complete drawing sets are prepared to permit-submission standards, reviewed internally, and delivered in the agreed format.
Submission Support
We support the permit submission process, respond to authority comments, and issue revisions as required to achieve approval.
