Strong and successful track record
Working with municipalities and authorities across Ontario
Why Choosing DAR for your project?

DAR Engineering & Design understands the priorities of developers and builders. Our engineering process is designed to reduce RFIs, minimize change orders, and support efficient construction.
- Clear communication between owners, architects, and contractors throughout the project stages.
- Early identification of coordination and constructability issues
- Consistent involvement of the same engineering team from design to construction
- Cost-effective, constructable engineering solutions
- Applying proven experience from similar projects
- Coordinated resources to meet construction schedules and milestones
Engineering Scope & Project Phases
DAR offers end-to-end MEP engineering services throughout the full design development phases and construction lifecycle, including:
- Site Plan Application (SPA)
- Base Building MEP Engineering Design
- Building Permit Application & ESA Plan Review Submission
- Tender, Construction, and Closeout Support
Our team works closely with municipalities, utility providers, and Authorities Having Jurisdiction (AHJ) to ensure efficient approvals, code compliance, and construction-ready documentation.
Site Plan Application (SPA)
We prepare comprehensive municipal-ready engineering documentation to support Site Plan Control approvals and planning submissions.
Our SPA engineering services include:
- Concept-level electrical and mechanical system design
- Preliminary HVAC strategies and equipment layouts
- Electrical load studies and utility servicing coordination
- Site and exterior lighting design with photometric compliance
- Coordination with civil, architectural, planning, and landscape consultants
- Responses to municipal review comments and revisions
Base Building Engineering Design
DAR delivers coordinated base building MEP engineering designs focused on constructability, efficiency, and long-term building performance.
Base building services include:
- Electrical power distribution and lighting systems
- HVAC design, ventilation calculations, and equipment sizing
- Plumbing, drainage, and fire protection systems
- Life safety, emergency power, and fire alarm systems
- Low-voltage and communications infrastructure
- Interdisciplinary coordination and clash mitigation
- Issued-for-Permit (IFP) and Issued-for-Construction (IFC) drawings
Building Permit Application Engineering
We provide permit-ready electrical and mechanical engineering drawings that meet municipal and AHJ requirements and facilitate efficient permit approvals.
Permit services include:
- Electrical load calculations and service sizing
- HVAC heat loss and heat gain calculations
- Detailed electrical and mechanical permit drawings
- Fire alarm and life safety design
- Engineering sealed drawings and reports
- Responses to plan examiner and municipal comments
