Commissioning & Testing in United States
End-to-end acceptance testing, documented results and a handover pack that stands up to audit. delivered in United States by engineers who work to the standards, safety regime and documentation expectations of this market. Mobilisation from Ashburn, VA in 24 hours. Northern Virginia alone holds more data-centre capacity than most countries, and the standards stack is different from Europe — TIA rather than EN, NFPA 70E arc-flash rules, and union labour considerations in several markets. An engineer arriving with European assumptions will fail a sign-off.

The United States market
Northern Virginia alone holds more data-centre capacity than most countries, and the standards stack is different from Europe — TIA rather than EN, NFPA 70E arc-flash rules, and union labour considerations in several markets. An engineer arriving with European assumptions will fail a sign-off.
We mobilise from Ashburn, VA and Chicago and Dallas and Bay Area with a target of 24 hours to site. Hubs in Ashburn VA, Chicago, Dallas and the Bay Area give 24-hour mobilisation. Coast-to-coast work is scheduled rather than on-call.

How we deliver commissioning & testing here
Commissioning in United States produces the evidence pack that closes the project: Certification to TIA-1152 (Level IV / IVe) for copper, fibre to TIA-526-14 with OLTS and OTDR traces. Every test is traceable to a link, an outlet or a rack, because an aggregate pass rate is not something an auditor can use.
- Test plan agreed in advance, naming the standard, the limits and the pass criteria
- Copper and fibre certification on 100% of links, with failures re-terminated and re-tested
- Native test files delivered alongside the human-readable report, so results can be re-verified independently
- Power-on and functional checks recorded per rack, including failover where it is in scope
- Punch list closed out and re-tested before the handover is signed
Standards and compliance in United States
Work is signed off against the standards that actually apply here, not the ones our engineers are most familiar with. In United States that means ANSI/TIA-568.2-D and 568.3-D as the primary reference, with certification to tia-1152 (level iv / ive) for copper as the test regime.
Site safety runs under NFPA 70E arc-flash risk assessment and PPE category. We supply certificates before mobilisation rather than on request.
Standards applied on site
- ANSI/TIA-568.2-D and 568.3-D for copper and fibre cabling
- ANSI/TIA-569 for pathways and spaces, TIA-606 for administration and labelling
- ANSI/TIA-942 for data-centre infrastructure tiering
- BICSI TDMM as the installation reference
- SOC 2 Type II for service organisations
- HIPAA where protected health information is in scope
- FedRAMP and CMMC where federal workloads are involved
- State privacy laws, including CCPA/CPRA in California
Site access and safety
Ashburn and other major markets require photo ID, background screening and often a badging appointment days in advance. Union jurisdiction applies to some electrical work in certain metros.
- NFPA 70E arc-flash risk assessment and PPE category for energised work
- OSHA 10 or 30 hour training, plus site-specific orientation
- Lockout/tagout under OSHA 29 CFR 1910.147

Local questions
Working in United States
Do you certify to TIA-1152 rather than IEC 61935?
Yes. US projects are certified to TIA-1152 Level IV or IVe, with fibre tested to TIA-526-14. We can additionally supply IEC 61935 results where a European parent company requires them.
Are your engineers NFPA 70E and OSHA trained?
Engineers working on or near energised equipment hold current NFPA 70E training and OSHA 10 or 30 cards, and we follow the site's arc-flash boundary and PPE category rules.
How do you handle union jurisdictions?
We identify union jurisdiction at scoping and either work within it or flag it before you commit. Discovering it on site is expensive for everyone.
