MEP SERVICES
DAR Engineering & Design provides practical, construction‑ready electrical and mechanical engineering solutions for commercial, residential, industrial, and mixed‑use projects across Ontario. Based in the Greater Toronto Area (GTA), we support developers, architects, and contractors with coordinated, code‑compliant designs that integrate seamlessly into real‑world construction workflows.
Our team focuses on delivering value‑engineered MEP systems for new builds, renovations, and tenant fit‑outs—prioritizing constructability, clear coordination, and efficient approvals. By aligning technical requirements with project budgets, schedules, and municipal standards, we help reduce construction risk and keep projects moving smoothly from design through occupancy.
Electrical Engineering Services
Our electrical engineering services deliver safe, reliable, and energy-efficient power and systems design, supporting high-performance building operation across all project phases.
Lighting Design
- Interior, exterior, and site lighting design for commercial, residential, and mixed‑use developments.
- Roadway and subdivision lighting design with optimized distribution and municipal compliance.
- Architectural lighting coordination for commercial and residential buildings.
- High‑bay and low‑bay lighting solutions for industrial facilities.
- Specialty lighting for sports complexes, courts, and performance environments.
- Advanced lighting control system designs tailored to project requirements and client preferences.
Power Distribution Design
- Electrical load calculations and service sizing
- Electrical distribution equipment specifications
- Cabling, conduit routing, and trenching layouts
- Emergency power and standby generator systems
- Power distribution single line diagrams
- Coordination with local hydro for service applications
- Submission for ESA plan review
Life Safety & Fire Alarm Systems
- Emergency and egress lighting design, including exit signage and emergency illumination optimized for visibility, reliability, and code compliance.
- Fire alarm system design in full compliance with the Ontario Building Code (OBC), NFPA standards, and Authority Having Jurisdiction (AHJ) requirements.
- Integration of life‑safety systems with building power distribution, ensuring proper circuiting, backup power, and emergency response functionality.
- Coordination of detection, notification, and monitoring systems to support safe evacuation and streamlined approval processes.
Communications and Security Systems Design
- Voice and data cabling infrastructure designed for reliable communication networks across commercial and institutional facilities.
- Sound, public address (PA), and conference room audio systems engineered for clarity, coverage, and seamless integration.
- Audiovisual (AV) and TV distribution systems supporting presentations, digital signage, and multi‑zone media delivery.
- CCTV and security camera system design for enhanced monitoring, safety, and site security.
Load Calculations & Electrical Capacity Assessments
- Electrical load estimation for existing and proposed conditions
- Evaluation of existing electrical service capacity and distribution systems
- Assessment of added major electrical loads (HVAC, EV chargers, equipment, kitchens, process loads, etc.)
- Identification of required service upgrades or mitigation strategies
- Coordination with utility providers and Authorities Having Jurisdiction (AHJ)
- Documentation to support building permit and utility approval processes
By accurately assessing electrical capacity early, we help clients optimize their investment and avoid unexpected service upgrades, approval delays, and construction disruptions.
We provide Professional Engineering stamped reports with the load assessment to present to Electrical Safety Authority, Utility companies (Hydro) and other AHJs.
This service is essential for projects involving increased electrical demand, including residential conversions, commercial remodels, tenant improvements, and industrial expansions.
