Arc flash studies, short-circuit analysis, protective device coordination and SKM modeling for facilities across New England.
Our Services
Focused electrical engineering consulting — from system modeling and analysis to stamped engineering documents.
Arc Flash Studies
Incident energy and arc flash boundary calculations, study documentation and equipment labels.
Short-Circuit Studies
Available fault-current calculations and equipment duty evaluation.
Protective Device Coordination
Review of breaker and fuse settings, time-current curves and coordination opportunities.
SKM Power System Modeling
Development and updates of electrical distribution models using available records and field information.
Electrical One-Line Diagrams
Readable existing and proposed electrical distribution diagrams, with field verification as scoped.
PE Electrical Engineering
Electrical calculations, stamped documents and design-build engineering support within the responsible engineer's licensed scope.
Arc Flash & Distribution Studies
An effective study begins with reliable system data. We review the available one-line drawings, equipment information and protective device details, identify missing inputs and define the field work required.
Study methodology and deliverables are defined for the project, considering applicable NFPA 70E, IEEE 1584 and NEC requirements.
Depending on the agreed scope, deliverables may include:
- Electrical system model and updated one-line diagram
- Short-circuit and equipment duty results
- Protective device coordination curves and setting recommendations
- Incident energy and arc flash boundary calculations
- Equipment labels and an engineering report
From Field Data to Engineering Deliverables
A structured process — from initial scope definition through final report delivery and discussion.
Define the Scope
Confirm facility boundaries, study objectives, deliverables and schedule.
Collect and Verify
Review drawings and gather equipment, conductor and protective device information. Perform field verification as scoped.
Model and Analyze
Develop the SKM model and complete the agreed electrical studies.
Engineering Review
Review results, assumptions and recommendations.
Deliver and Discuss
Provide the agreed report, drawings, coordination curves and labels, and discuss the findings.
Support for Owners & Project Teams
We work with facility managers, building owners, electrical contractors and design-build teams.
Commercial Buildings
Office, retail and mixed-use facilities requiring distribution system documentation and analysis.
Life Sciences & Laboratories
Facilities with critical power requirements and complex distribution systems.
Manufacturing
Industrial facilities with significant electrical loads and equipment duty considerations.
Healthcare
Hospitals and medical facilities where power reliability and safety documentation are essential.
Higher Education
Campus and institutional facilities with diverse electrical infrastructure.
Technology Facilities
Data centers and technology-intensive buildings with demanding power system requirements.
Tell us about your facility and the electrical question you need to resolve.
