Connect your overseas project with Chinese engineering resources and equipment supply. One brief. Clearly defined work packages.
For industrial owners, EPC contractors, system integrators and project buyers.
Start with a focused assignment or combine design coordination and equipment sourcing. BuJuan structures the engagement around your project, then identifies the appropriate specialists and manufacturers.
Turn initial drawings, load lists and site requirements into a technical brief that design teams and suppliers can work from.
Identify and engage suitable engineering resources for the agreed disciplines, deliverables and review process.
Invite manufacturers to quote against the same technical basis, so you can assess price alongside scope and compliance.
For detailed or construction-stage work, the proposal identifies the design organization, responsible reviewers and any local approval requirements before that scope is committed.
A clear route from brief to RFQ
Agree the information, responsibilities and issue stage before design resources and manufacturers begin work.
Application, site, schedule, available drawings and governing requirements.
Confirm disciplines, interfaces, deliverables and the review responsibility.
Coordinate concept or RFQ drawings with the selected engineering resources.
Issue a common technical basis and review vendor responses against it.
Explore typical engineering packages and applications. We define disciplines and deliverables around your site information and project requirements.
Transformer and E-house package; MCC and heavy-duty drives; cables and earthing; valve and instrumentation interfaces.
Site load list, motor schedule, available utility supply and process interface drawings.
Discuss this scopeTransformer, MV switchgear and LV distribution; layout coordination; cable entries, foundation interfaces and vendor documentation.
Single-line diagram, site layout, utility requirements and installation responsibilities.
Discuss this scopeMotor feeder panels, variable-speed drives and control interfaces; equipment schedules and manufacturer RFQs.
Existing system drawings, new machine loads, shutdown constraints and control philosophy.
Discuss this scopeDC supply, inverter/UPS, battery and bypass requirements; technical response schedules and supply exclusions.
Critical load profile, required autonomy, supply voltage and site environmental conditions.
Discuss this scopeTransformer datasheet, preliminary GA, terminal and footprint interfaces; testing and supplier document requirements.
Existing nameplate, installation dimensions, protection interfaces and replacement schedule.
Discuss this scopeInstrument transformer specifications, mounting interfaces and supplier clarification schedules.
Utility requirements, ratios, accuracy classes, burden and insulation requirements.
Discuss this scopeDeliverables are agreed before work begins. Each issue records its purpose, revision, assumptions and review status.
Design fees, procurement services and equipment supply can be combined in a BuJuan proposal. Final formats, design responsibility, fees and milestones are project-specific.
A closer look at the drawing types that can support equipment enquiries, layout coordination and technical review.
Reference drawings demonstrate typical sheet formats and information levels. Before work begins, each project defines its design basis, responsible designer, review stage and deliverables.
Low-voltage systems connect people, equipment and building operations. These concept sheets show how separate systems can be scoped and coordinated.
Original, editable DXF concept sheets prepared for tender-stage scope discussions. These are not construction documents and are not approved for permitting or procurement quantities. Device selection, coverage, cable sizing, routing, fire strategy, local codes and design responsibility require confirmation by the project’s qualified engineer. DXF files are software-neutral exchange files; no AutoCAD license is required to inspect them in compatible CAD software.
Reference standards to verify for each project—not a compliance statement: GB 55024-2022 (building electrical and intelligent systems) · GB 50311-2016 (integrated cabling) · GB 50116-2013 (fire alarm systems). Project-country regulations and current editions govern.
