When this service helps
A service upgrade is an infrastructure project, not simply a larger breaker. New building loads, equipment replacement, and electrification can affect the utility connection, metering, service equipment, and distribution throughout the property. A planned engineering scope helps owners understand those connections before procurement and construction commitments are made.
What the engineering scope addresses
We assess the existing service arrangement and proposed demand, then develop the applicable one-line diagrams, equipment layouts, feeder and riser design, and coordination information. The study considers physical access, electrical-room constraints, equipment clearances, and connections to retained systems. Utility coordination addresses the supply-side requirements relevant to the proposed work.
Planning the next step
Occupied buildings often need a phasing plan that accounts for outages, temporary arrangements, and access to apartments or tenant spaces. Those issues should be discussed with management and the contractor early. Final scope, costs, utility work, and scheduling depend on verified conditions and the relevant approvals; engineering planning helps identify the dependencies rather than promising a fixed utility timeline.
Potential deliverables
- Service, switchboard, feeder, and riser design
- Con Edison service coordination and technical submissions
- Metering, equipment clearances, and phasing considerations
The proposal confirms the exact deliverables and any site visits, follow-up review, filing support, or construction services included.
What to prepare
- Existing service drawings and meter arrangements
- Proposed equipment loads and project phasing
- Available utility correspondence and service requests
- Electrical-room access and known operational constraints
Share what is available and identify records that are missing. We can help define the initial engineering scope around the information and access your project has.
