New standby generator
Coordinate the generator, transfer equipment, service, distribution, grounding, and accepted site interfaces.
Generator and ATS engineering
Commercial Generator and ATS Engineering
A coordinated electrical permit package for commercial standby generators and automatic transfer switches, built from actual equipment, load, service, and site information.
Commercial Permit, Structural and MEP Engineering - Fast, Coordinated, and Built Around Your Approval Deadline.
Contractor-friendly scopeWritten fee and scheduleOne ordinary AHJ cycle
Scope and availability review
Project availability is determined after reviewing the scope, project location, jurisdictional requirements and required engineering disciplines. Additional insurance or specialty clearance may be required before contract or production.
Customer trigger
Generator projects that need more than a cut sheet
ATS addition or replacement
Document normal and emergency sources, transfer logic basis, ratings, feeders, and one-line changes.
Load and capacity question
Develop the accepted load basis and identify missing operating information before design.
Permit rejection
Address electrical comments tied to generator, ATS, service, grounding, or equipment documentation.
Installer coordination
Give the generator installer and electrical contractor a defined engineering package and responsibility matrix.
Foundation interface
Coordinate with the separately scoped equipment-foundation service when a pad or anchorage design is needed.
Starting fees
Premium commercial scope with controlled pricing
Final fee depends on the accepted jurisdiction, existing information, building and equipment complexity, required disciplines, field needs, and deadline.
Defined commercial standby system.
Multiple sources, services, or unusual operating conditions.
May be credited when stated in the proposal.
Proposal and payment policy
- No payment is required before scope and availability review and acceptance of a written proposal.
- Projects at or below $3,000: 100% before production after proposal acceptance.
- Projects from $3,001-$25,000: 60% deposit; balance before final sealed issuance.
- Projects above $25,000: 50% deposit, 30% at coordinated draft, 20% before final issuance.
- Rush service: 40% premium when accepted in writing.
- Site visits, surveying, geotechnical work, testing, laboratory services, and scope changes are separately priced.
Defined deliverables
What the accepted package may include
- Existing and proposed one-lines
- Accepted electrical load calculation
- Generator and ATS sizing/design basis
- Grounding and bonding details
- Equipment layout and clearance coordination
- Panel and equipment schedules as applicable
- One ordinary AHJ review cycle
Turnaround control
Complete qualified requests received during operating hours target a same-business-day scope response. The written proposal confirms the production start, required intake, responsible-professional availability, review milestones, and final issuance date before payment.
Scope boundary
Hospitals, high-rise emergency systems, hazardous locations, medium voltage, data centers, standalone arc-flash studies, fuel-system design, acoustic studies, emissions permitting, and specialized structural dynamics are excluded unless qualified professionals accept them.
Project information
Send address, AHJ, records, and the real deadline
Use the project description to identify the full project address and authority having jurisdiction. Upload the files already available; additional photographs or records may follow during scope review.
Required intake
- Project address and AHJ
- Generator and ATS manufacturer/model/cut sheets
- Service one-line and utility information

Responsible-charge statement
Engineering services are performed under the responsible charge of the appropriately licensed Grand Street Engineering professional for the applicable project and jurisdiction. Grand Street Engineering does not offer after-the-fact sealing, rubber stamping, or a stamp-only service.
Owner, equipment, geometry, criteria, or scope changes require a written change order. Final issuance remains subject to professional review and required payment.
Scope and availability review
Start with the facts you already have
Include the project address, AHJ, requested service, current problem, permit comments, deadline, and decision-makers. The five-minute response target applies during operating hours; the same-day proposal standard applies after qualification and sufficient scope information.

Frequently asked questions
Scope and payment questions
Does this include the concrete pad?
Only when equipment-foundation and anchorage engineering is separately listed or coordinated in the proposal.
Can you use installer-selected equipment?
Equipment can be evaluated when complete cut sheets, ratings, dimensions, weights, and operating information are provided.
Is emergency-system work included?
Not automatically. High-rise, healthcare, legally required, and other high-consequence systems require specific competence and responsible-charge acceptance.
What starts the schedule?
The proposal identifies the deposit, required intake, and confirmed start condition. Rush scheduling carries a 40% premium when accepted.
