Report ID: 701

Report Overview

A TWC found that scaffolding was not built in accordance with the approved design drawings and a number of unauthorised modifications were made.

Report Content

A Temporary Works Coordinator (TWC) was requested to inspect and issue a Permit To Load for designed access scaffold on a site. Prior to visiting the site, the TWC was issued with a copy of the approved design drawings and design check certificate. On inspection of the recently completed scaffolding with Scafftag attached, the TWC found that the scaffolding was not built in accordance with the approved design drawings and a number of unauthorised modifications were made. The TWC immediately removed the Scafftag and provided the site manager with a list of construction deviations from the approved design drawings for remediation. The deviatons included:

  • Base plates incorrectly placed on sole boards
  • Beams not installed in accordance with the manufacturers instructions - bracing was either missing or at incorrect centres
  • Puncheon standards missing couplers
  • Ties back to the structure were either missing or incomplete with girder clamps not being used in pairs
  • Insufficient scaffold tube projection through numerous fixings (due to site constrains not being allowed for in the design)

The design was revised as required and remedial measures undertaken on site prior to the TWC re-inspecting the scaffolding and issuing a Permit to Load.
