Pascal Design Group delivers construction-ready engineering for power and gas utilities — distribution, transmission, substation, and GIS — built to code, on schedule, and stamped by licensed professionals.
From overhead distribution and high-voltage substations to power-generation controls and field inspection, we own the work from planning through as-builts — for electric and gas alike.
Overhead and underground primary & secondary design, pole loading, and system hardening for reliable last-mile delivery.
High-voltage line design and structure engineering with PLS-CADD modeling for new builds and rebuilds up to 345 kV.
Physical and electrical substation design — from greenfield builds to capacity upgrades.
Geospatial mapping, data conversion, and asset modeling that keep your network of record accurate.
Distribution main and service design for gas utilities — replacement programs, extensions, and regulator stations.
A specialized team supporting generating stations — from outage planning and project controls to instrumentation and turbine work.
Experienced journeyman, field, and construction personnel delivering inspection and oversight for electric and gas projects.
We embed with utility engineering teams as a scalable extension of their workforce — adding capacity without adding overhead.
Capacity for capital programs, hardening, and large rebuild backlogs.
Main replacement and integrity-driven distribution design.
Right-sized engineering support for lean rural co-op teams.
Distribution & substation design for city-owned systems.
Design partner for engineer-procure-construct delivery.
Pascal Design Group is a woman-owned utility design firm headquartered in Phoenix, Arizona, serving electric and gas utilities across the Western United States.
Founded by Jamie & Derek Riccitelli, Pascal Design Group pairs hands-on field experience with disciplined engineering — the kind of judgment that only comes from time on the line.
Our leadership team brings more than five decades of combined experience across electric and gas utility design and field services. From our Phoenix headquarters, we partner with utilities, cooperatives, and EPCs throughout the West — and put that experience behind every package we stamp.
Every package moves through the same accountable workflow — so you always know what's coming and when.
Kickoff, constraints, and field collection to ground the design in reality.
Calculations, PLS-CADD / ArcFM modeling, and code checks against NESC & B31.8.
Joint-use, ROW, and agency coordination handled in parallel.
Sealed, construction-ready packages with full BOM and staking.
Reconciled redlines flow back into your network of record.
A sample of recent engagements across power and gas. Replace the placeholders with your own project photography.
Full physical & electrical redesign and capacity upgrade for an aging distribution substation.
Pole loading and storm-hardening design across 240+ miles of overhead primary.
Multi-phase distribution main replacement program with regulator station upgrades.
We're built around the realities of utility programs — compliance, schedule pressure, and the need for clean data downstream.
Deliverables are reviewed and stamped by licensed professional engineers — every package, every time.
NESC, NEC, and ASME B31.8 compliance is baked into our process, not bolted on at review.
Flex up for capital seasons and storm response without the cost of permanent headcount.
GIS-integrated workflows mean as-builts reconcile cleanly into your network of record.
Share your scope, timeline, and codes — we'll respond with an approach and a team within two business days.
