Services

Electrical engineering for design, construction, and operating facilities—power systems, studies, controls, commissioning, and owner support.

Electrical system studies

Arc flash, protection coordination, and short-circuit analysis as a clear service line within the wider practice.

Arc flash studies

An arc flash study calculates incident energy and arc flash boundaries at electrical equipment so workers know approach limits and required PPE. Studies are typically modelled in Bentley EasyPower from a verified single-line and equipment data.

What it covers

System model, bolted fault and arcing fault evaluation, incident energy results, PPE categories or cal/cm² levels, and labelling recommendations consistent with applicable CSA and NFPA practice.

When it is needed

New or upgraded distribution; major equipment changes; outdated or missing labels; insurance, audit, or OH&S requirements; after significant load or utility changes.

Typical deliverables

Study report with assumptions and results
Updated single-line as required
Arc flash labels (or label schedule)
Mitigation options where energy is high

Breaker & protection coordination

Coordination studies set protective device curves so a fault is cleared by the nearest upstream device. That limits the outage area, reduces equipment damage, and supports selective operation of breakers, fuses, and relays.

What it covers

Time-current curves for breakers, fuses, and relays; settings recommendations; review of sensor ratios, trip units, and protective device options available on site.

When it is needed

New switchgear or MCC installations; nuisance tripping; plant expansions; after utility or transformer changes; when arc flash mitigation depends on faster clearing times.

Typical deliverables

Coordination study report
TCC plots for key paths
Recommended device settings
Notes on selectivity vs. arc flash trade-offs

Short-circuit studies

Short-circuit (fault current) analysis determines available fault levels throughout the system and checks that equipment interrupting and withstand ratings are adequate.

What it covers

Utility and on-site contribution; three-phase and line-to-ground fault levels as applicable; comparison of results to equipment ratings; identification of overdutied devices.

When it is needed

Equipment specification or replacement; utility service changes; generator or large motor additions; as the foundation for coordination and arc flash studies.

Typical deliverables

Fault current summary by bus
Equipment duty evaluation
Recommendations for undersized devices
Model inputs suitable for follow-on studies

Power & facility systems

Detailed engineering for distribution and building systems on industrial and facility projects.

Power distribution

Medium- and low-voltage distribution design, including single-lines, equipment specification, and layouts for industrial and institutional facilities.

Lighting systems

Interior and exterior lighting for plant, process, and support areas, including emergency and exit lighting where required.

Fire alarm systems

Fire alarm design and modifications coordinated with architectural and mechanical scopes and applicable codes.

Hazardous area classification

Area classification for gas, dust, wet, and corrosive environments to support equipment selection and installation methods.

Uninterruptible power supplies (UPS)

UPS sizing and integration for critical loads such as controls, servers, and process systems.

MCCs, VFDs & motor systems

Motor control centres, variable frequency drives, servo drives, and related motor circuit design for process and utility loads.

Controls, delivery & advisory

From process controls through construction support and owner representation.

Instrumentation & controls

Process control design, specification, and documentation—including PLC/DCS panels, remote I/O, communication networks, field instrumentation, and HVAC control systems.

Commissioning

Commissioning plan development and commissioning supervision so systems are verified against design intent before handover.

Construction support

Contract administration, equipment and shop drawing reviews, construction QA/QC, project management, site inspections, and record drawings.

Preliminary engineering

Site assessments, project feasibility studies, project budgets, and system reliability or obsolescence reviews before detailed design.

Owner’s engineer on retainer

Owner advocacy and owner’s engineer support on retainer—scope review, design oversight, and technical representation.
