Rights of Light Technical Review
Independent review of third-party technical information, analytical geometry and Rights of Light results used to support informed project discussions.
What information is needed to prepare a Rights of Light model?
The usual starting information includes point-cloud or measured survey data, existing drawings, proposed architectural information, relevant site context and the agreed analytical scope. The quotation will identify any additional information needed.
Can CAD Services Studio review an existing third-party model?
Yes. Existing third-party geometry and technical information can be checked against the available source information, with discrepancies and assumptions recorded for the project team.
Can the model be prepared or registered in MBS?
Yes. MBS-compatible model preparation and registration can be included where required by the agreed project workflow.
Can both existing and proposed conditions be modelled?
Yes. Existing and proposed geometry can be prepared as coordinated model states, together with the relevant surrounding context and analytical geometry.
Can you support an existing consultancy team?
Yes. Confidential subcontract, white-label and additional technical capacity can be provided by agreement, with the working arrangement and responsibilities confirmed for the project.
Does CAD Services Studio provide legal Rights of Light advice?
No. The service is technical. Legal advice, legal entitlement, representation, valuation, damages advice, legal agreements and legal negotiation remain outside the scope.
