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 the work sectors but do not reflect changes in market
conditions affecting profit and overheads, site wage rates, bonuses or
materials price discounts/premiums. In the current market, many costs
recorded here are still rising but prices charged to clients have been falling
sharply.

Market conditions are recorded in Davis Langdon’s quarterly
Market Forecast (last published 30 October).
