DeLeo self-performs civil and utility construction scopes under one coordinated operation — one schedule, one point of contact, no subcontracting of primary scope. Our LIUNA-affiliated crews bring the experience and training to execute reliably in active, constrained environments across the Northeast.
Discuss Your Scope
DeLeo self-performs all of the following scopes with its own crews.
DeLeo installs concrete-encased ductbank from the design footprint through final encasement — excavating the trench corridor, placing and spacing conduit per utility specifications, installing spacers and tie-wire, pouring concrete encasement, and backfilling to grade. Work is performed within active utility corridors, often with energized cable systems in adjacent conduit. Conduit routing, bend radii, and pull-point spacing are executed to utility standards.
DeLeo installs precast and cast-in-place vault and manhole structures to utility specifications — excavating the structure footprint, preparing the subgrade, setting precast elements or forming and pouring in-place concrete, and integrating conduit entries, sump systems, and frame/cover assemblies. Structure placement is coordinated with ductbank geometry, grade constraints, and pull-point spacing requirements.
DeLeo performs the trenching, foundation work, ductbank tie-ins, and conduit entry work at substation boundaries under the access controls and protection requirements established by the utility's protection engineers. Crew entry into the yard requires an approved protection plan. Lockout/tagout procedures, phased switching plans, and outage window coordination with utility dispatch are applied on every substation civil project.
DeLeo performs full civil scope at energy facility sites — site preparation, earthwork, structural concrete for equipment pads and transformer foundations, underground utility installation, access road and yard paving, storm drainage, oil-water separators, secondary containment, and vapor recovery infrastructure. Work is scoped to engineering documents, executed to equipment foundation tolerances, and coordinated with facility operations where sites remain partially active during construction.
Trench excavation, pipe installation in all soil conditions, structure placement, manhole and catch basin setting, tie-in to existing systems, and surface restoration. This scope runs integrated with broader civil and underground electrical utility projects — not as standalone municipal programs.
DeLeo maintains 24/7 on-call crews for contracted utility clients — available to mobilize for cable failures, structure compromises, storm-related underground damage, and other urgent civil utility failures. Emergency work is executed under the same safety protocols as planned work: utility locates completed, protection coordination established, proper shoring in place before crew entry. Response time does not change what is required before anyone goes into the trench.
Utility locates are completed and verified before any trench opens. Protection plans are established before crews enter restricted zones. Sequencing is planned to maintain system continuity and outage windows are coordinated with utility dispatch.
Scope review with utility construction management, utility locates, protection engineer consultation, sequencing documentation, traffic control permitting — completed before groundbreaking.
Crews trained in minimum approach distances, high-voltage proximity PPE requirements, and utility-specific protection procedures. No crew enters a restricted zone without a coordinated protection plan in place.
Planned cutover sequences, temporary routing, and phased ductbank installation keep circuits online while permanent infrastructure is installed and tied in.
If you are planning underground electrical work, substation civil scope, energy facility development, or utility infrastructure in the Northeast — contact DeLeo. Scope is reviewed directly, questions are practical, and proposals are based on what the work actually requires in the field.
