Support the approved building-control functions, not just the dashboard screen. HJ reviews named controllers, sensors, schedules and interfaces under a documented maintenance contract, with defect tracking and change approval. HVAC plant, electrical equipment, software licences and third-party integrations retain their separately appointed owners.
Conceptual planning path — not an as-built drawing or project photograph.
Tell us the fault and your location. Diagnostic attendance, repairs, parts and any travel charges are confirmed with you before work.

It sits in Annual Maintenance Contract under AMC. The final deliverable is shaped by the intended outcome, the installed or proposed environment and the interfaces that must be owned, supplied, integrated and tested.

From the initial brief to the handover record: what to prepare, check and confirm with HJ.

Agree BMS, field-device, network and mechanical/electrical plant boundaries. Changes to schedules, setpoints or interlocks require the plant owner; safety functions are not altered as routine tuning.
Verify selected points against the field condition, alarm routing and agreed control response. An attractive trend screen alone does not prove correct sensors or safe plant operation.
Retain point checks, approved configuration changes, backup ownership, unresolved dependencies and a prioritised defect report.
HJ coordinates assessment, engineering, installation, integration, testing and lifecycle support only for the scope recorded in the quotation. ISD handles catalogue, model, datasheet, supply and availability enquiries. Customer, consultant, builder and appointed-specialist responsibilities remain explicit.
Final scope, quantities, compatibility, access, programme, availability and responsibility are confirmed during assessment and quotation.
Installed platform, authorised ownership, parts compatibility and serviceability are checked before any repair or restoration outcome is proposed.
See related systems, how HJ installs them, and support for equipment you already have.
Use the answers as a planning boundary; site conditions and written scope remain decisive.
No. The contract lists control functions and assets, with plant, electrical, network and software responsibilities separately assigned.

Tell us what the system is, what is going wrong or what you want checked. HJ will confirm the work needed, explain who is responsible for what, and agree the next step with you before any work starts.
