Scope of services
From the constant-current regulator in the vault to the last light on the approach, LEAN designs, tests, and delivers the full electrical and navigational picture. One senior team, one integrated design.
Runway, taxiway, and apron lighting from the base can to the control system — LED fixtures, series circuits, constant-current regulators, and airfield lighting control & monitoring (ALCS/ALCMS), including SMGCS CAT III controllable stop bars.
Navigational aids from siting through energization: localizer and glideslope, ILS upgrades from CAT I to CAT III, RVR, DME, VOR, and next-generation ground-based augmentation systems — with FAA Non-Federal procurement coordination and obstruction analysis.
Design, siting, and commissioning of approach and visual-guidance systems — MALSR, ALSF-2, PAPI/VASI, and REILs — engineered to FAA geometry and verified with field photometrics.
Medium- and low-voltage power for the airfield and its facilities — 12kV distribution, feeders and duct banks, switchgear, airfield vaults, and standby/emergency power with automatic transfer.
Building and terminal power distribution, short-circuit and coordination studies, backup generators, UPS, and automatic transfer switches — plus 400Hz and pre-conditioned air for gates.
Aircraft performance analysis, instrument flight procedure development, magnetic-variation (MAGVAR) changes, obstruction and airspace (7460) analysis, and safety-risk management for constrained fields.
The discipline we were founded on: in-situ field photometric testing of installed airfield fixtures to verify FAA intensity and beam-coverage tolerances. LEAN co-authored the TRB/FAA Technical Center LED airfield-lighting O&M manual.
Energy and resiliency studies that de-risk decisions — solar feasibility with FAA glare analysis and site-ranking, photovoltaic design, microgrid and electrical-capacity studies for airports and federal sites.
Airport security and low-voltage technology — CCTV, perimeter intrusion detection (PIDS), access control (ACAMS), and security duct-bank infrastructure, from design through acceptance testing.
Electrical construction management, submittals, RFIs, and field inspection on the most operationally-sensitive closures — including SFO's 81-day and OAK's 13-day runway shutdowns.
Advisory-circular-compliant design and direct coordination with the FAA and FAA Technical Center — where LEAN routinely contributes to new standards, advisory circulars, and orders.
Airfield lighting control systems (latest-generation ALCS/ALCMS) and SMGCS routing — the software and controls that let a tower operate the airfield safely in low visibility.
How we engage
We lead the design, hold the client relationship, and take the electrical engineer-of-record responsibility end to end.
Primes bring us on for the airfield electrical & NAVAID scope they can't afford to get wrong — as a trusted specialty sub.
Standing task-order support — the fast, senior help airports keep on speed dial for whatever the airfield needs next.
Describe the problem — a runway, a vault, an approach, a study — and we'll scope the electrical solution with you.
