Engineering Knowledge Base
Robert reads the standards your engineers reference every day. Free public-domain libraries are included with every OpsWork tier. The paid subscriptions your organisation already holds — BSI Knowledge, IEC, NEC4 — you connect yourself after install, from your admin console. OpsWork never holds the licence.

Included with OpsWork
Robert comes pre-loaded with the public UK HV standards your engineers reference — ENA documents, HSE guidance, the Distribution Code, the NERS framework and UK statutory codes — free for every OpsWork tier. Licensed standards (ISO, BSI, IEC, NEC4) are not free and are not redistributed by OpsWork; you connect or add those from your own subscription, shown separately below.

If your organisation is already ISO 9001, 14001, 45001 or 27001 certified, you already hold those standards — add the clauses you work to from your own certified copy in your standards library, and Robert references them by clause. OpsWork does not redistribute ISO text. UK statutory requirements (GDPR, Companies Act, IR35, CIS, Bribery Act) are free from gov.uk and HMRC.
No additional licence required for the free libraries. The free public-domain libraries above (ENA, HSE, Distribution Code, NERS, UK statutory codes) are included with every OpsWork tier — Foundation, Standard, and Enterprise. Licensed standards (ISO, BSI, IEC, NEC4) are yours to connect. Automatic tracking of new published versionsin development
Connected to your subscriptions
Most UK HV consultancies already hold BSI, IEC and NEC4 subscriptions. You connect your own — OpsWork never holds the licence — and Robert indexes what your subscription gives you access to, answering with the clause reference so your engineer can check the controlled source. Connection status differs by publisher and is shown against each below.in development
BS, BS EN, ISO and IEC adopted standards
BS 7671 — IET Wiring Regulations
BS EN 50522 — Earthing of HV installations
BS EN 60076 — Transformer ratings
BS EN 62271-200 — AC switchgear above 1kV
BS EN 62305 — Lightning protection
BS EN 61140 — Protection against electric shock
BS EN 60099-4 — Surge arresters
BS EN 60044-1 — Current transformers
BS EN 60898-1 — Circuit breakers
BS EN 61936-1 — Power installations above 1kV AC
Robert reads the BS and BS EN standards your BSI Knowledge licence covers. ISO management standards are covered separately above.
International Electrotechnical Commission publications
IEC 60287 — Cable current rating
IEC 60228 — Conductors of insulated cables
IEC 60502 — Power cables 1–30kV
IEC 60076 — Power transformers
IEC 60909 — Short-circuit currents
IEC 62271 — High-voltage switchgear
IEC 60044 — Instrument transformers
IEC 61936 — Power installations above 1kV
IEC standards are typically included in BSI Knowledge subscriptions in the UK.
NEC Digital Professional licence
NEC4 ECC — Engineering and Construction Contract
NEC4 ECS — Engineering and Construction Subcontract
NEC4 PSC — Professional Service Contract
NEC4 TSC — Term Service Contract
All Options A–F including compensation events and early warnings
Secondary Options X1–X29 and Y(UK) clauses
There is no NEC publisher API, so NEC4 reaches OpsWork by upload from your own NEC Digital Professional licence — clause numbers and titles, indexed by reference. James and Michael then reference those clauses by number during NEC4 obligations and Application for Payment workflows.
Your framework-licensed documents
DNO technical documents are licensed to framework contractors. If your organisation holds the rights, Robert indexes them inside your own tenant — searchable like the public standards, but only by your engineers, only inside your data boundary.
DNO frameworks supported during implementation:
The DNOs you work with are recorded at install and seed the library's DNO checklist entries; your framework-licensed documents are indexed from your own uploads.
Annual subscription costs sit outside OpsWork pricing. Most UK HV consultancies already hold BSI Knowledge, IEC and NEC4 Digital subscriptions as a routine cost of business. You connect your existing access yourself, after install, from your admin console — OpsWork never holds the licence. If you don't currently subscribe, we can point you to the publishers at their standard rates — no mark-up.
How engineers use it
Your engineers type the question they need answered. Robert searches across every library — free and licensed — finds the relevant clauses, and returns the answer with source references attached.in development
"cable sizing 132kV XLPE burial depth"
IEC 60287 + ENA TS 09-12
"earth fault clearance time 33kV substation"
BS EN 50522 clause 5.3.2
"G99 application limits for 5MW solar farm"
ENA G99 Type B
"NEC4 compensation event timebar"
NEC4 ECC clause 61.3
"NERS Section 13 competency evidence checklist"
NERS v10 Section 13.4
"33kV switchgear arc flash IP rating"
IEC 62271-200
Every answer cites the source document, clause and version. Engineers approve all design outputs.
