Live-Facility & Security Coordination
Building next to live racks means one wrong breaker or badge can take down a client. AAAT3 plans and manages construction inside operating data centers, with MOPs, access control and change management that protect uptime.
- MOPs & change control
- Access & badging
- Escorts & security
- Outage planning
- Dust & vibration control
By the numbers
What poor coordination in a live facility costs
Outages where human error played a part
Uptime Institute Outage Analysis, 2026Operators who say their last impactful outage could have been avoided with better management, processes or configuration
Uptime Institute Outage Analysis, 2026Operators who say most human error outages came from staff not following procedures
Uptime Institute Outage Analysis, 2025Operators whose last major outage cost more than $100,000. 1 in 5 cost more than $1 million
Uptime Institute Outage Analysis, 2026What’s included
Construction that keeps the facility running
Every task near live systems gets a written plan, an approval and someone watching it get done.
Methods of procedure (MOPs)
A MOP turns risky work into a step by step script with checks and a way back.
- MOP writing and review
- Change control and approvals
- Rollback and contingency steps
- Pre-task briefings
Access and security
Clients want to know who is in the building, where and why.
- Badging and escort programs
- Restricted zone and cage rules
- Tool and material control
- Contractor sign in and out
Protecting live systems
Dust, vibration, water and heat can trip IT gear even when nobody touches it.
- Dust and debris barriers
- Vibration and drilling controls
- Water and leak protection
- Fire system impairment planning
Project management and consulting
Project management and consulting for live facilities
AAAT3 can manage the construction interface with operations, write and run your MOPs, or audit how contractors work in your building.
Construction and operations interface management
We act as the bridge between contractors and the facility team, scheduling work so uptime stays first.
Best for: Expansions and retrofits inside running sitesMOP and change management program
We write, review and track MOPs and change requests, and run the go or no-go calls.
Best for: Sites with frequent changes near critical systemsContractor access and security program
Badging, escort, tool control and site rules designed and enforced.
Best for: Colocation and federal sites with strict securityOutage and shutdown planning
Planned shutdowns broken into steps with owners, timelines and rollback plans.
Best for: Tie-ins, cutovers and equipment swapsContractor work audits
Unannounced audits of contractor practices against your rules and MOPs.
Best for: Owners who want proof contractors follow the rulesIncident and near miss investigation
Root cause analysis and corrective actions after an outage or near miss.
Best for: Any site after an eventHow it works
From work request to safe completion
Request
Scope, location and systems at risk.
Risk review
Impact on power, cooling and network.
MOP
Step by step plan with checks and rollback.
Approve
Change board and client sign off.
Execute
Escorted, watched and logged.
Close
Verify systems and capture lessons.
Rule of thumb: no work near a live system starts without an approved MOP, a rollback plan and someone with the authority to stop it.

Common questions
What is a MOP?
A method of procedure is a step by step script for work on or near critical systems. It lists each action, who does it, how it is checked and how to roll back if something goes wrong.
Why do outages happen during construction?
Most involve human error, often someone not following the procedure. Clear MOPs, approvals and supervision prevent most of them.
Can AAAT3 manage contractors inside our facility?
Yes. We manage the interface between construction and operations, including MOPs, access, escorts and daily audits.
Do you plan shutdowns and cutovers?
Yes. We break shutdowns into steps with owners, timelines, checks and rollback plans, and run the go or no-go call.
Do you work on secure or federal sites?
Yes. We build badging, escort and tool control programs and work within federal security requirements.
