Projects: foundation drilling Projects & Case Studies

Dig‑It, Inc. delivers safe, constructible solutions for utility and commercial foundations across the Midwest. Founded in 1994 and woman‑owned, our team specializes in drilled shafts/caissons, hydro excavation, limited‑access and low‑headroom drilling, direct‑embed foundations and CMP installations. Browse the case studies drilling highlights below to see how we approach complex scopes and tight schedules—and how we measure success.

Project portfolio at a glance

Our project portfolio spans utility and commercial work:

Transmission line drilled shafts and anchors

Substation caissons and equipment foundations

Hydro-excavation projects for daylighting, slot trenching and precision potholing

Limited‑access or low‑headroom drilling inside stations, under bridges, or near energized assets

Direct‑embed foundations and CMP installations for poles and structures

For sector‑specific solutions, see Hydro-Excavation.

Transmission

Overhead line drilled shafts

Scope typically includes large‑diameter drilled shafts for tangent and dead‑end structures, with reinforcing steel, rock sockets where required, and fluid management. Crews coordinate closely with utility outage windows and environmental constraints, maintaining safe clearances and traffic control.

Access, soils, and schedule solutions

Challenge:

Limited ROW access and variable soils (soft clays to hard till/rock)

Solution:

Matting, temporary work pads and the right tooling for changing geology; real‑time adjustments guided by constructability review

Outcome:

Foundations completed within outage windows and tested per spec; project completion completed to landowner standards

Substations and utilities

Substation caissons and equipment pads

Tight sites demand precise rig selection, spoil control and coordination with other trades. We handle caissons for transformers, breaker pads, and cable trench interfaces, managing slurry or dry methods as the geotechnical profile dictates.

Outage‑driven schedules and QA

Challenge:

Compressed outage windows and multi‑contractor interfaces

Solution:

Pre‑task planning, daily coordination with the GC/owner, and documented inspections

Outcome:

On‑schedule turnovers with clean as‑built documentation and quality records

Hydro-excavation projects

Hydro excavation is critical for utility verification, safe exposure and slot trenching where tolerance is tight or subsurface risk is high. Typical scopes include potholing to confirm line depth/offset, trenching for conduits, and precision daylighting around sensitive assets.

Challenge:

Unknown subsurface congestion

Solution:

Non‑destructive hydro excavation to verify clearances before drilling

Outcome:

Fewer strikes, cleaner sites, and faster transitions to drilled foundation work

Limited access and low‑headroom

When structures, overhead lines, or interiors restrict height and swing, we mobilize low‑clearance rigs and specialized tooling. We plan ingress/egress, ventilation (as needed), and spoil handling to maintain safe, continuous operations in tight spaces.

Direct embed & CMP installations

Direct‑embed pole foundations and CMP casings often pair with transmission or lighting scopes. We set, plumb, and backfill per specification and verify compaction as required.

Challenge:

Variable backfill and compaction criteria

Solution:

Controlled lifts, testing coordination and thorough documentation

Outcome:

Spec‑compliant installations ready for structure erection

See Direct Embed & CMP Installation for service details.

How we measure success

  • Safety performance and zero‑incident execution (see our Safety & Quality program)
  • Spec compliance: diameters, depths, rock sockets, reinforcement and concrete verification
  • Schedule adherence to outage windows and critical path
  • Minimal rework and change exposure through pre-construction planning
  • Landowner satisfaction and project completion quality
  • Clear documentation: daily reports, test results, and as‑built documentation
