Steel price
A movement of £100/t in the delivered mesh price typically changes the installed rate by about £0.90–£1.10/m² after laps and waste.
Laps and waste
Standard allowances of 10–15% are usual, while irregular geometry can add a further £1.00–£2.50/m².
Pour size
Small or intermittent pours can increase the fixing rate by 20–45% through repeated mobilisation and lost gang productivity.
Access and handling
Restricted craneage, manual distribution or double handling commonly adds £2.00–£5.00/m².
Chairs and spacers
Heavy-duty supports, close spacing or unusual cover requirements can add £1.00–£4.00/m².
Congestion and openings
Frequent penetrations, trimming and clashes with other reinforcement can raise labour cost by 25–60%.
