25 marquee operators across 21 countries trust VB Engineering with their As-Built Engineering engagements.
VB Engineering As-Built Engineering from the Shanghai operations entity. Country-native standards overlay. RPEC + CEng MIE signed. Native handover to Wistwin · the sister Industry 4.0 digital twin SaaS.
For brownfield Sinopec integrated refining-petrochem complexes in China: the LiDAR-backed reconciliation walk, the as-built drawing rebuild, and the structured handover that lets your plant team trust the documentation again.
Across the Sinopec and CNPC integrated refining-petrochem complexes, the Yangtze River Delta chemicals corridor, and the Guangdong EV-battery processing cluster, a reconciled as-built drawing package is what every regulator, insurer, and digital-twin handover ultimately depends on. China is the world's largest industrial electrical engineering market by volume but the work shape is unusual: most facilities are recent (2005-2020 vintage) and operate under the GB / GB/T national standards, which interoperate with IEC. The brownfield retrofit opportunity is concentrated in the petrochemical complexes (Sinopec · CNPC · CNOOC), state-owned power generation, and the EV-battery and rare-earth processing build-out. China's industrial estate is younger than the West's but rapidly accumulating brownfield retrofit demand. The state-owned operators are running multi-year safety-improvement programmes that require comprehensive electrical-system re-baselining. Multinational JVs accelerate this by requiring international-standard documentation alongside the GB-compliant package.
P&ID and instrumentation drafting follows ISA S5.1 with PIP PIC001 as the reference for process-industry symbology. Isometric drafting follows ISO 6428. Where the operator references GB 50054 (Code for design of low-voltage distribution) · GB 50217 (cable selection) · GB 50058 (hazardous-area · IEC-aligned) · GB/T 50063 (electrical instruments), the deliverable formatting layer aligns to it; line numbering, equipment tagging, and revision-control discipline are invariant.
GA drawing reconciled against the as-found equipment layout. Plot-plan updated with the new equipment positions, elevations, and access-route updates. Tie-in to civil + structural drawings where the operator package is integrated.
Process flow diagram (PFD), heat and material balance, and utility flow drawings updated against the as-found process configuration. Where the process has drifted from the original design (a recurring finding on plants over 20 years old in China), we document the drift and align the deliverable to the operating condition.
Equipment tag list, line list, and instrument index reconciled to the point cloud. The full package hands directly to the Wistwin digital-twin platform or the operator's asset-management system with no re-registration required.
LiDAR-backed reconciliation against the legacy P&ID / GA / isometric package. Every discrepancy logged with point-cloud screenshot, equipment-tag location, and recommended disposition. The log becomes the basis for the formal as-built revision.
P&ID drafted to ISA S5.1 in your CAD environment (AutoCAD P&ID, SmartPlant P&ID, AVEVA P&ID, Bentley OpenPlant). Where the existing P&ID is recoverable, we mark up to the as-found condition; where it is not, we rebuild from the field plus operator interviews.
Isometric drafting from the LiDAR point cloud against ISO 6428 conventions. Spool list, fabrication isometric, and weld-map deliverable structure depending on the downstream workflow.
Three China engagements (a Sinopec refining-petrochem complex, a Xinjiang upstream gas-gathering field, and a Guangdong gigafactory) that illustrate the working pattern:
an integrated 12 MTPA refining-petrochem complex with 110 kV intake and 10 kV distribution.
The engagement: Multinational JV demanded IEEE 1584-2018 arc flash baseline alongside the GB-compliant electrical-safety regime; bilingual Mandarin-English deliverable.
a gas-gathering field with 35 kV ring main and dozens of wellhead substations.
The engagement: Field-wide coordination drift over the network expansion; mass relay setting reset + arc flash recalculation + bilingual labels.
a 50 GWh battery cell manufacturing plant with 110 kV intake and 10 kV distribution.
The engagement: First-of-kind plant arc flash baseline against international standards; DC arc flash methodology for battery formation lines integrated with AC distribution.
