Maximizing Safety, Efficiency & Compliance
Scheduled plant shutdowns—also called turnarounds or outages—let you inspect, repair, upgrade, and commission equipment that can’t be serviced online. When planned well, shutdowns extend asset life, boost performance, and reduce the risk of costly unplanned downtime. Bunney’s Inc. plans and delivers shutdown services for power, water, and industrial facilities across Arizona and the Southwest.

What’s Included in Scheduled Shutdown Services
A coordinated, time-bound stoppage covering: scope definition, materials and contractor coordination, equipment inspections, repairs/replacements, system upgrades, safety testing, start-up, and documentation. Durations range from a few days to several weeks based on scope and critical path.
Industries served
-
Energy & power generation
-
Water & wastewater treatment
-
Oil & gas, mining, and processing

Why Planned Shutdowns Matter
-
Preventive maintenance: Address issues before failure (pumps, valves, boilers, controls).
-
Safety improvements: Verify protective systems; exercise emergency protocols.
-
Upgrades & modernization: Automation, energy-efficient components, and capacity adds.
-
Regulatory compliance: Align with OSHA, EPA, and owner requirements.
-
Lower total cost: Planned downtime beats emergency shutdowns every time.

FAQs
How far ahead should we plan a shutdown?
For multi-system outages, start 90–180 days out to lock scope, crews, and materials.
Can some work be done pre-outage?
Yes—pre-fabrication, staging, and certain inspections reduce critical-path time.
How do you control scope creep and discovery work?
With a change-control process, contingency planning, and a prioritized corrective-actions list.
What documentation do we receive at closeout?
Full QA/QC package: permits, NDE results, pressure-test logs, torque/calibration records, and as-builts.
Do you handle emergency/forced outages?
Yes—our teams mobilize quickly across Arizona and the Southwest.
