Earthworks

1. Has the workforce been given clear instruction in relation to the work at hand, in particular, quality requirements.
2. Have the foreman and leading hands been communicated the requirements from the relevant construction method statement?
3. Are the foremen using the verification checklist on a daily basis to control quality in the field?
4. Layer thickness is accurate and control measures are being used?
5. The spotter and plant operator are aware of the material requirements?
6. Is the material - lots homogeneous - free of organic or deleterious material - free from segregated stone or excess fine patches - free of oversize - no visible soft spots/heaving
7. Has uniform spreading, mixing, watering and compaction of material been achieved?
8. Are there methods used to control moisture in the fill material?
9. Is there a process in place to protect survey markers during operations?
10. Are protective measures in place for movement of heavy construction plant over and around pipe/ box culvert structures?
11. Are embankments sealed off and shaped to allow water to drain away (no pounding)?
12. Have environmental control devices been put in place prior to commencement of work and reestablished at the completion of works?
13. Are batters stable, free of loose material?
14. Are the batter gradients accurate and uniform?
15. Are the batters being progressively landscaped?
16. Is the plant and equipment being used suitable for the work being performed?
17. Any other item, activities underway that demonstrate commitment to improving levels of workmanship?

Drainage

1. Has the workforce been given clear instruction in relation to the work at hand, in particular, quality requirements.
2. Have the foreman and leading hands been communicated the requirements from the relevant construction method statement?

5. Are there sufficient survey pegs and controls in place to achieve tolerances?
6. Level checks are being carried out and recorded uponplacement of all the pipes..
7. Diversion channels and temporary crossings installed priorto commencing work (where required).
8. Excavations (excluding pipes) have a clear width between the structure wall and face of the excavation is at least 300mm or 1/3 of the height of the face of the excavation,whichever is greater.
10. Are protective measures in place for movement of heavy construction plant over and around pipes/box culvert structures?
9. Does the bedding extend to the full width of trench and todesign depth
10. Are lifting holes been effectively sealed to prevent the ingress of materials?

15. Are protective measures in place for movement of heavy construction plant over and around pipes/box culvert structures?
16. Open drains are trimmed to a uniform surface free of irregularities and graded to ensure free flow of water.
17. Is the scour protection been installed in accordance with the design (i.e. correct with, length, depth and rock size)?And fits into surrounding ground levels.
18. Have environmental control measures (sediment, erosion,dust, etc..) been put in place prior to commencing work andre-established at the completion of works, unless they form part of the environmental control measure?
