Trench Backfill

Tacit Tessera C M 1 006 PL · 1 · Construction · Machine · collected by Steady Eddie · Specified — written down and numbered, not issued. The name is the address; the number is how the register writes it down.

Scope — what it covers
Will cover returning spoil or imported material to a trench in lifts over a laid service. The depth limit is the top of the protected service plus its stated cover, and the package claims placing and levelling only.
Refuses — where it stops
Work adjacent to live services; trench work with a person in the trench; lifting or craning with a suspended load. It proposes. It never authorizes.

Built from
Will be built from the task package written for this work in Steady Eddie's trenching and underground utilities register: its bounds, the site information it requires, its pre-start checks and its refusals. Nothing has run on a machine.
How it is tested
Will be checked with the machine stationary and its engine off, then by a single run at the group's own yard, measured by survey afterward, with the stop exercised. A name and a date carry every step.
Tiers offered
By the machine — none offered while the entry is Specified
