Common Site Mistakes That Cause Gateway 3 Approval Failure

Most Gateway 3 failures are caused by site-level issues rather than design intent.

Common problems include:

  • Missing fire stopping evidence
  • Unrecorded changes on site
  • Work not matching approved details
  • Incomplete inspection and test records
  • Poor organisation of site data

These are usually the result of rushed construction or weak site controls, not deliberate non-compliance.

Gateway 3 failures are often avoidable if evidence is managed properly from day one.
 
In most cases, Gateway 3 failures are not the result of complex technical problems, but of basic site controls breaking down over time. Small gaps in records, changes made under pressure, or unclear responsibilities can quickly accumulate into major compliance issues.

Time pressure is a common factor. When programmes tighten, recording and checking work is often treated as secondary to progress. This approach usually backfires, as the time saved during construction is lost many times over during approval delays.

Another frequent issue is fragmented responsibility. When evidence is spread across multiple contractors or stored inconsistently, it becomes difficult to demonstrate a complete and reliable record at the end of the project.

Projects that perform well at Gateway 3 tend to have clear routines for recording, reviewing and storing site information. Evidence is treated as part of the build process, not as a separate administrative task.

The most reliable way to avoid Gateway 3 failure is to assume that every critical activity will need to be proven later. When evidence is managed consistently from the start, final approval becomes far more predictable.
