Underground Engineering Agent · Phase 7
A Universal Vault Model for underground distribution. Pulling tension, ampacity, fault current, OH→UG conversion. Native catalogs for padmount enclosures and S&C PMH switchgear. Same shared pole graph as the overhead agent.

Capabilities
Each tool reads and writes the Universal Vault Model. Geometry, equipment, conduit, cables, and analysis all share the same shape — and the same circuit graph extends through risers into the overhead model.
5 tools — create vaults, add ports, install equipment, export complete vault models.
7 tools — segments, runs, conductor placement, bends, trench profiles.
7 tools — NEC conduit fill %, three-cable jam detection, pulling tension through bends, intermediate vault placement.
4 tools — Neher-McGrath with soil/depth/grouping corrections, emergency ratings, voltage drop.
5 tools — vault selection, OSHA / NEC 110.34 working space, bending radius, padmount clearances.
8 tools — unified overhead + underground circuit graphs, shortest path, alternate feeds, single points of failure.
3 tools — dead load, conduit sizing, termination and arrester specifications.
9 tools — overhead-to-underground conversion, voltage cutover, reconductoring, storm hardening, wildfire risk scoring.
4 tools — cable fault withstand (ICEA), concentric neutral duty, arc flash (IEEE 1584).
4 tools — layout optimization, multi-circuit derating, concrete encasement, trench dimensions.
What sets it apart
Primary (sizes #5, #6, #7) and secondary enclosures with port elevations pre-populated. Modeled from utility standard drawings.
All twelve models (PMH-3 through PMH-19) with per-compartment layouts. Enforces utility new-only / replacement-only / discontinued rules. Auto-pairs companion splice vaults.
Wall-face and elevation placement on padmount enclosures. Auto-connect picks optimal port pairs from vault layout.
Flags cables in the D/d 2.8–3.2 danger zone before they get installed.
Merge overhead and underground nodes and edges into one graph. Find paths, redundancy, and OH→UG conversion candidates.
One call returns vault placement, pulling feasibility, riser details, and a cost estimate.
Drop in your utility's standard doc numbers and watch the enclosures snap into place with the right wall ports. We'll walk you through pulling tension, ampacity, and an OH→UG conversion study.
