Civil & Utility Infrastructure
Supporting utility and energy infrastructure projects with field-proven execution—specializing in underground utilities and complex site development within active environments.
DeLeo executes underground electrical and civil infrastructure in active utility environments — ductbank and conduit in live corridors, vault and manhole construction adjacent to energized systems, substation civil work under utility protection protocols. Crews coordinate directly with utility construction managers on sequencing, outage windows, and protection plans.
Concrete-encased ductbank, conduit runs, and cable pathways installed inside active utility corridors — adjacent circuits stay energized throughout. Executed inside active distribution networks across the Northeast.
Precast and cast-in-place electrical vaults, manholes, and access chambers — installed to utility specification with full conduit entry, sump, and frame/cover integration. Structure placement is coordinated with ductbank geometry and future cable pull distances.
Site preparation, structural concrete (equipment pads, transformer foundations), drainage, and access infrastructure for substations, fuel terminals, and industrial energy sites — delivered to engineering tolerances, not general grading standards. Scoped around equipment footprints and facility operations.
Conduit entry, ductbank tie-ins, and trenching inside active station yards — sequenced around switching operations and executed under the protection protocols established by the utility's protection engineers. The station stays running throughout construction.
A. DeLeo Construction Company has operated as an underground utility and civil contractor in the Northeast energy sector since 1994. Work is performed inside active distribution corridors, substation yards, fuel terminals, and industrial energy facilities where construction must proceed without forcing system outages.
The workforce is LIUNA-affiliated, trained in confined-space entry, lockout/tagout, and the protection protocols required in active electrical environments. Field supervision coordinates directly with utility construction managers on sequencing, outage windows, and protection plans throughout execution.
DeLeo's foremen coordinate directly with utility construction managers on sequencing, outage windows, and protection requirements before and throughout every project. Work is sequenced to maintain system continuity and executed under the safety protocols required in active electrical environments.
Scope review, utility locates, protection engineer coordination, sequencing plans, and traffic control permitting are completed before groundbreaking — not in parallel with it.
Crews are trained in minimum approach distances, PPE requirements for high-voltage proximity, and the utility-specific protection procedures required when working adjacent to energized systems.
Phased installation, planned cutover windows, and temporary routing allow distribution systems to remain operational while permanent infrastructure is installed and tied in.
Field supervision coordinates directly with utility construction managers on sequencing, protection plans, and outage windows. Al DeLeo IV is directly involved in every contract.
DeLeo's crews are trained and cleared to work in energized corridors, substation yards, and active fuel terminals. Protection plans are coordinated with utility operations before any work begins in a restricted zone.
DeLeo self-performs the civil scope and the underground electrical utility scope under one coordination structure. One team, one schedule, one accountability chain — sequencing decisions are made in the field without cross-contractor delay, and the utility construction manager has a single point of contact throughout execution.
DeLeo's utility contract relationships are performance-based renewals — tracked against response time, execution quality, schedule reliability, and safety record across every program cycle.
DeLeo works in urban utility corridors, active substations, fuel terminals, and pipeline sites — constrained right-of-way, energized equipment, environmental compliance requirements, and aging infrastructure. Every project requires permits, utility coordination, and protection sequencing before any excavation opens.
