Bring us
the hard part.
EPV turns complex industrial scope into controlled, field-ready work. The code basis, schedule, materials, inspection points, and turnover requirements are carried from planning through execution so the completed asset and the completed record arrive together.

Work we are built for
Regional work.
Industrial consequences.
Focused on the facilities and systems that keep energy and process infrastructure operating.
Power generation
Power piping, boiler and HRSG work, tube and drum repairs, equipment setting, platforms, and outage support.
Oilfield construction
Well pads, tank batteries, produced-water systems, flowlines, gathering systems, skids, civil, and site support.
Midstream facilities
Compressor stations, pump stations, launcher and receiver sites, metering, mainline tie-ins, and facility piping.
Gas plants
Processing facilities, dehydration, treating, metering, utility systems, structural supports, skids, and modules.
Data centers + mission critical
Prefabricated piping, modular assemblies, cooling-water systems, equipment connections, supports, and documented turnover for mission-critical facilities.
Surface mineral + materials processing
Construction and mechanical support for MSHA-regulated surface processing facilities: crushing, screening, conveying, milling, slurry and process piping, pumps, tanks, equipment setting, structural supports, shutdowns, and documented turnover.
EPV Aerospace
Aircraft fueling and de-icing fluid systems, including controlled piping fabrication, modular assemblies, equipment connections, supports, testing coordination, and turnover records. Material traceability, documented welding, inspection records, and customer-specific quality requirements are built into execution.
EPV’s mining-sector scope is surface-facility construction and mechanical support for processing and materials-handling systems. It is not presented as underground mining or production-mining operations.
Capability without the catalog
What can EPV take off your critical path?
We organize scope around systems, work packages, constraints, and turnover boundaries—so engineering, procurement, fabrication, field execution, quality, and closeout move as one plan.
Fabricate
Pressure vessels, industrial and data-center pipe spools, aerospace fueling and de-icing piping, mineral-processing piping and chutes, modular assemblies, process modules, structural components, supports, and specialty-alloy work—planned from approved drawings, material requirements, weld maps, and inspection points.
Install
Heavy equipment setting, rotating equipment, piping systems, supports, rigging, alignment, and grouting coordinated through defined work fronts and field-ready packages.
Maintain
Turnarounds, emergency response, exchanger bundle extraction, hydro-blasting, boiler and exchanger work, repairs, and replacements sequenced around isolation, access, inspection, and return to service.
Verify
Welding controls, PMI, inspection coordination, material traceability, NDE, test records, and code documentation linked to the component and drawing they support.
Deliver
Schedule visibility, installed quantities, open-item control, linked records, and turnover packages developed progressively—not assembled after the field work is complete.
EPV service lines
A broader scope. One controlled execution system.
Our service lines are organized around the work customers need performed and the controls required to complete it—not isolated trades handed off from one group to another.

Specialized outage services
Open it. Clean it. Inspect it. Put it back right.
EPV supports maintenance work that often sits directly on the outage critical path. The scope is planned around access, rigging, cleaning, inspection, repair, and reassembly—not treated as disconnected tasks.
Exchanger bundle extraction
Bundle pulls and reinsertion, channel and head removal, puller setup, rigging, inspection support, repair readiness, reassembly, and torque control.
- Horizontal and vertical exchanger access planning
- Bundle-puller, crane, and transport coordination
- Inspection, retube, and repair support
- Reassembly, bolting, and test readiness
Hydro-blasting
High-pressure water cleaning for exchanger tubes and bundles, piping, vessels, and process equipment, coordinated with outage sequencing.
- Tube-side and shell-side cleaning support
- Process-equipment and piping cleaning
- Cleaning acceptance and inspection access
- Work-package and closeout documentation
FIELD NOTE 003Bundle extraction is an integrated sequence of access, isolation, rigging, cleaning, inspection, and controlled reassembly.
Quality Thru Code™
One drawing.
One source of truth.
A drawing is not decoration. It is the controlled interface where scope, material identity, fabrication status, inspection, testing, and turnover meet. EPV builds the project record from the same current information used to release and verify the field work.
- DefineProject requirements, code basis, system boundaries, and acceptance criteria.
- ControlApproved revisions, work packages, constraints, and release status.
- TraceComponents, heat numbers, MTRs, weld identity, and qualified procedures.
- VerifyHold points, examinations, NDE, PWHT, pressure testing, and exceptions.
- Turn overReconciled drawings, linked records, approvals, and a complete system package.

Integrated execution planning
The work. The plan. The record.
A strong execution plan is more than a schedule. It defines how scope will be released, built, verified, measured, and accepted—and who owns each decision along the way.
Establish the basis.
Confirm scope boundaries, code and specification requirements, deliverables, responsibilities, interfaces, and acceptance criteria.
Build executable work packages.
Connect drawings, materials, labor, access, equipment, permits, hold points, and turnover requirements to the schedule.
Make readiness visible.
Work moves forward when prerequisites are satisfied, current documents are available, and constraints have an accountable owner.
Control the field record.
Installed quantities, material identity, weld status, inspections, tests, redlines, and open items are captured as the work progresses.
Close by system.
Reconcile records, resolve exceptions, complete testing, and assemble accepted turnover packages progressively with the work.
FIELD NOTE 002If the field cannot see what is ready, what is constrained, and what proves completion, the plan is not finished.
Before mobilization
Nine questions worth answering early.
Mobilization should confirm more than manpower and equipment. It should establish the work face, current information, inspection sequence, material readiness, and the records required for final acceptance.
