Amenities are the part that gets judged
Depot amenities carry an unusual load. Crews arrive together at the start of a shift, use the facilities within a short window, and return together at the end. Lockers, boot areas, showers and lunchrooms absorb mud, dust and moisture in concentrated bursts rather than steadily, and a frequency set for an office environment will always look inadequate against that pattern.
The scope should be built around those two peaks. A reset before the morning arrival and a second attendance after the afternoon return will hold the standard far better than a single mid-shift clean, even if the total hours are similar. Consumables need checking against the same pattern, since a dispenser that empties by mid-morning is effectively empty all day. Where crew numbers vary seasonally, the plan should say how the amenity attendance changes with them rather than holding a fixed figure through the year.
