- Mismatch between the drawings and the calculation report
- Inconsistent design code basis across documents
- Foundation assumptions not backed by a geotechnical report
- Incomplete coordination between architectural and structural drawings
Resubmission process
Revised drawings and/or calculations addressing the specific technical query are resubmitted through the same system — a fresh application is not normally required.
Realistic timelines
Timelines vary with project complexity; resubmission cycles caused by incomplete documentation are the most common driver of delay, not the authority's baseline processing time. We don't guarantee approval outcomes or timeframes — see our A-Z compliance service for how we structure submissions to minimize avoidable delay.
