Order quantity
Orders below about 500m² can increase the rate by £12–£25/m² because mobilisation and minimum-load costs are spread over less work.
Haul distance
Extended travel from the coating plant can add £2–£7/m² through higher transport costs and reduced delivery reliability.
Site geometry
Tight radii, narrow strips and numerous tie-ins typically add 10–30% by reducing paver output and increasing hand finishing.
Working hours
Night, weekend or possession working commonly increases the rate by 15–35% through premiums and shorter productive windows.
Material specification
Polymer-modified binders, special aggregates or enhanced performance requirements can add £5–£15/m².
Formation condition
Local regulating, cleaning and correction of an uneven receiving surface can add £4–£18/m² before productive base-course laying starts.
