Monitoring Excavation

Free S2 questions: Monitoring Excavation

These questions are in the practice set above. Answer them there to see the correct option and the explanation for each.

• Scenario: a supervisor reviews the log for an odd-shaped excavation. It is not a core, not a micro trench and not a narrow trench, and its own reinstatement area is well over the small-opening limit for its own road type. The crew has logged it as a "small opening." What should the supervisor do?
• Scenario: a footway designated as a principal route and used by an exceptionally large number of pedestrians is a high duty footway. The authority has demonstrated, and had registered, that it has been constructed and maintained to a standard above the Code's own general performance requirements, with its own declared intervention criteria. The supervisor's inspection finds the just-finished reinstatement meets the Code's ordinary requirements but falls short of the authority's registered, stricter criteria. What must the supervisor do?
• Scenario: an interim reinstatement has been in place for some months and the permanent reinstatement has not yet been carried out. A supervisor's routine check finds no settlement, no surface defect and no sign it has drifted out of the standard it met when first laid. What should the supervisor decide?
• Scenario: a trench has been dug so narrow that the compaction plant catches against the trench wall whenever it is worked in beside the apparatus, and the operative has to stop repeatedly to free it. The surround specified for the job is a granular material that has to be compacted. What should the supervisor do before backfilling proceeds?
• Scenario: a long trench excavation uncovers material that may be of historical interest at one end. The crew stops digging in the immediate area of the find and informs the authority, as SROH requires, but wants to carry on excavating a different section of the same trench, well away from the find, in the meantime. What must the supervisor require?
• Scenario: when a natural-stone footway is opened, several of its modules are found already cracked into fragments by existing damage from before the works. The site foreman agrees with the undertaker's own resident engineer that the fragments can be treated as spoil rather than removed and stored. The supervisor is asked to sign this off as meeting the Code's "unless agreed otherwise" exception. What must the supervisor do?
• Scenario: constructing a compliant reinstatement in a deteriorated area is not possible, and time constraints mean no agreement on an alternative method can be reached with the authority. The crew is about to proceed after nothing more than a verbal heads-up to the authority. What must the supervisor require before work continues?
• Scenario: after completion, it comes to light that a section of the reinstatement does not conform to one of the Code's own requirements outside its performance section, unconnected to any settlement or surface failure. The crew treats the guarantee period as already running from the completion date. What must the supervisor verify?
