Statutory design and working documentation serve different purposes. The first sets out the adopted design for the applicable review process. The second contains the detail required for construction and installation. Having one package does not mean the other is complete.
01Purpose of statutory design documentation
Statutory design documentation describes architectural, structural, technological and services solutions within the required project scope. It explains the design basis and the coordination of key parameters.
Its extent depends on the use of the building and the proposed works. A new-build documentation scope should not be applied automatically to a limited fit-out.
02What working documentation contains
Working drawings establish dimensions, levels, setting-out, connections and installation details. Specifications identify materials and equipment; schedules connect them to rooms and work packages.
For interiors, partition, floor, ceiling, lighting and service outlet plans must agree. Contractors should be able to execute the design without having to redefine the architectural intent.
03Managing revisions
Record changes in the document issue register. Each package should carry a status, issue date and revision. Equipment substitutions can affect dimensions, power, cooling and maintenance access across several disciplines.
Review the affected interfaces before site issue. Superseded documents should be withdrawn from active use while retaining the approval history.
04What the client should define
- Required disciplines, drawing packages, specifications and schedules.
- Handover formats, including editable files and models where included in the brief.
- Review procedures, revision allowances and acceptance criteria.
- Responsibility for design interfaces and change management.
- The scope of design supervision after documentation is issued.
