• Vacuum test not fewer than the number of manholes as shown in Table 22.5. Where projects contain both precast and cast in-situ manholes, view each type as a separate population. If any of the sample manholes fail the initial test, test all remaining manholes in that population.

Confirm Project Information

• Structures to be inspected and their details

• Testing specification requirements

Initial Work Area Inspection

• Is test area barricaded off or sufficiently delineated?

  Yes

  No

  N/A

• Is traffic control established?

  Yes

  No

  N/A

• Has a Safe Work Method Statement been completed and all control measures followed?

  Yes

  No

  N/A

• Has a Confined Space Risk Assessment & Entry Permit been completed?

  Yes

  No

  N/A

• Is the confined space equipment and procedures set up as per the Risk Assessment & Entry Permit conditions followed?

  Yes

  No

  N/A

• Structure lid removed and placed at a safe distance from the entry point

• Environmental controls installed as and if required

Inspection Steps

• Equipment checked and in good working order

  Yes

  No

  N/A

• Insert test plugs into structure inlets with extendable pole if possible so confined space risks are avoided

• Inflate plugs and add support as per manufacturer's specifications

• Place test plate, attach to vacuum pump and vacuum down manhole to test pressure

• Allow for vacuum to stabilise for an amount of time as per specifications

• Hold vacuum for time specified in specifications and record result

Disassemble Steps

• Disconnect hose from vacuum pump and release pressure from structure

• Remove test plate, release pressure from plugs and carefully retrieve plugs out of structure

• Replace structure lid, remove barricading and return all items to test unit

Final Demobilisation

• Notify client of result and to contact TestX office to arrange further testing or reports

• Calibrated gauge numbers used

• Inspector's remarks

• Photo of work area and inspected structures

  Media

• I declare that the inspection procedure was followed in accordance with the nominated specifications
