  • Is there adequate information relating to potential below ground<br>services in or near the proposed area of excavation?

  • Has a CAT survey of the proposed excavation area been<br>undertaken?

  • Have live services been isolated? Have any identified live services<br>been clearly identified and marked?

  • Has an excavation permit been issued by a competent person?

On Site Checks

  • Is a safe method used for installing supports e.g. one that does not<br>rely on people working within an unsupported trench?

  • If the sides of the excavation are stepped or battered, is the angle of<br>batter sufficient to prevent collapse?

  • If the sides of the excavation are stepped or battered, is the angle of<br>batter sufficient to prevent collapse?

  • Is the excavation inspected daily by a competent person, and are<br>weekly thorough examinations recorded?

  • Is there any evidence of water / soil ingress and / or movement /<br>stress on trench support systems?

  • Is there any evidence of contamination? (Is the work potentially<br>being undertaken on contaminated land)?

  • Waste disposal arrangement for spoil/contaminated spoil?

  • Are there adequate barriers to stop people falling into the<br>excavation and if vehicles tip into the excavation, are earth mounds<br>or properly secured stop blocks provided?

  • Is the excavation being carried out so as to not affect the stability of<br>buildings/structures/vessels/plant/etc?

  • Are materials spoil or plant stored far enough from the edge of the<br>excavation as to be unlikely to cause a collapse a the site?

  • Is the excavator fitted with a Safe Load Indicator (S.L.I.)?
