Price Indices of Selected Construction Materials (Base year 2005)

Methodological note on the Price Indices of Selected Construction Materials

Scope
The objective of the Price Indices for Selected Input Materials in Construction is to show the evolution of the cost of input materials incurred by the contractor.
Data collection For the preparation of the price indices, the Statistical Service conducts a monthly survey for a sample of suppliers. The reference date for the prices collected is the 15th each month. If the 15th is not a working day,
then prices are collected for the closest working day. Prices are valued excluding V.A.T. and delivery charges. Besides construction materials, an index is calculated also for gas oil with the difference that prices are collected every Thursday from a sample of petrol stations, within the context of the Consumer Price Index (CPI). The survey is carried out by telephone interviews and by fax.
Compilation method and dissemination practices
The price indices are based in year 2005, meaning that they show the evolution of the price of a certain material in relation to its average price in 2005. In the base year, the average of the price indices for the twelve months is 100,00. For example, a price index 112,35 for a material in a certain month implies that the price has gone up by 12,35% in relation to the average price of 2005. For the price indices of selected materials, we provide the following
additional information: · For Crushed Sand, Crushed Gravel and Gravel and Sand Aggregate, the index refers to selling prices on the truck at the quarry premises. · For Bricks and Ordinary Portland Gray Cement, the index refers to selling prices on the truck at the factory premises. · For Iron, the index refers to selling prices on the truck at the warehouse of the supplier.
· For Ready Mixed Concrete, the index refers to selling prices for delivery to a building site within a radius up to 10 km from the factory. · For Bitumen Asphalt, the index refers to selling prices for delivery at the buyer’s premises. · For Gas Oil, the index refers to selling prices in petrol stations. · For Structural Steel, the index refers to selling prices at the warehouse of the supplier. Note that index calculation for this material
starts in 2005. These indices are part of the overall Price Index of Construction Materials, which can be accessed by opening the file: CONSTRUCTION - PRICE INDEX OF CONSTRUCTION MATERIALS on the same web page. Note that the price index for gas oil is not included in the calculation of the total index.
