Build a multi storey apartment building — South Australia

The longest pathway in the database: design review, a Class 2 building under the National Construction Code, fire engineering, extended referrals, and strata registration at the end.

developmentClass 2 residential apartment building, multi storey, site already held skeleton compare across jurisdictions

This is a structural skeleton, not a measured process. The steps, the authorities and the sequence are researched from this jurisdiction's published requirements and are broadly right. The durations are a uniform template applied across all jurisdictions, so the differences between them on the comparison page are mostly an artefact of that template rather than evidence about Australia. Do not quote the day counts. Replacing them with sourced figures for even one jurisdiction would make this page genuinely useful.

Where the time goes

Critical-path days only. Steps that run alongside others are real work but do not lengthen the process, so counting them here would overstate the prize.

applicant	304d	Waiting on the applicant to supply or fix something.
assessment	225d	Someone is genuinely evaluating the merits.
queue	167d	Waiting behind unrelated work in a backlog.
scheduling	115d	Waiting for a person or committee to become available.

282 of 811 elapsed days are spent waiting for a person or a meeting rather than for a judgement to be formed. Removing that time changes no assessment standard and lowers no bar -- it is the cost of scheduling alone.

The process, step by step

Applies when: A Class 2 residential apartment building on a site the developer already controls, assessed by the local consent authority rather than as a state significant development.

3	Fire engineering performance solution assessment only if triggered Where the design departs from the deemed-to-satisfy provisions of the National Construction Code for a Class 2 building.

Machine-flagged questions

These are produced automatically from the dependency graph. They are questions for a practitioner, not findings. Each one needs a person who has run this process to say whether the constraint is real.

The same body asked more than once

sa-building (certification) appears at Obtain the building consent, Obtain the certificate of occupancy. Could these be a single sign-off?
sa-planning (assessment) appears at Design review panel, Lodgement and properly-made check, Assessment against the planning rules, Information request and amended plans. Could these be a single sign-off?
