Davis Langdon’s cost indices track movements in the input costs of
construction work in various sectors, incorporating national wage
agreements and changes in materials prices as measured by government
index series.

They provide an underlying indication of price changes and differential
movements in work sectors but do not reflect changes in market
conditions affecting profit and overheads provisions, site wage rates,
bonuses or materials’ price discounts/premiums.

Market conditions are recorded in Davis Langdon’s quarterly market
