Responsibility and evidence boundary
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.
Brand names identify compatibility or installed-platform enquiries only. They do not claim authorised distributor, service-centre, partner, warranty or parts status.
Regulated or multi-discipline work proceeds only after site assessment and confirmation of the competent, qualified or appointed persons, approvals, safe isolation and responsibility required for that scope.
Identity, image, credential and movement data require an authorised controller, lawful access, proportionate collection, retention rules and recorded administrator responsibility.
This focused topic remains connected to its complete system owner. Final models, quantities, interfaces and included work are confirmed in the assessed quotation.
