Mobilisation
A planer, sweeper and support crew typically create a minimum visit cost of £2,500–£5,000 before productive area is considered.
Planing depth
Each additional 25 mm of depth typically adds £2.00–£4.00/m² through reduced output, greater wear and increased arising volumes.
Quantity
Areas below about 500 m² can attract a 40–150% uplift because mobilisation and standing time are spread over limited production.
Waste haulage
Haul distance, wagon availability and recycling outlet charges can add £15–£35/t, broadly equivalent to £1.40–£3.20/m² at 40 mm depth.
Traffic management
Lane closures, night working and restricted possession periods commonly add £1.50–£6.00/m², with complex closures often priced separately.
Obstructions
Dense ironwork, kerb interfaces, ramps and hand-trimmed edges can increase the milling rate by 25–75%.
