The goal of most countries is the desire to maintain a stable price level of goods and services. This however, appears to be an uphill task given the incidence of inflation presently ravaging developing economies of the world. Inflationary increase in the price of construction materials has been one of the major banes to development and a contributing factor to frequent cost overruns and subsequently project abandonment. The research studied the effect of inflation on construction material prices in Nigeria from 1998 to 2007, using Lagos as the study area. The study aimed at establishing a relationship between inflation and construction material prices, so as to build a model for forecasting the effect of inflation on construction materials.

A comprehensive review of literature was structured to cover inflation, the Nigerian Economy and the construction industry while Data was collected from Nigerian Institute of quantity Surveyors (NIQS) journals, Central Bank of Nigeria (CBN) and National Bureau of Statistics (NBS) documents. Regression analysis was performed on the data, and the results showed that a third order polynomial equation relationship exist between cumulative inflation rate and construction material prices. Based on the results; the significant level of correlation reached, it was inferred that cumulative inflation rate can be used to predict the price of building materials.

From the descriptive analysis and literature survey carried out, it was discovered that inflation rates in Nigeria have been far from stable, and have affected material prices non-uniformly. Other macro-economic factors such as importation, interest rate, Gross Domestic Product (GDP) and political regimes also contribute to upward trend in price movement.

The study thus advocated for more involvement of construction professionals in Government policy making, a systematic reduction in importation level, more use of locally made building materials and development of the country’s construction data base to enable the usage of the Construction material inflation rate (CMIR) which will serve as a better computation method for fluctuation in material prices and consequently, more realistic estimating and cost planning.

Construction projects involve extensive use of materials. According to Obiegbu (2003), the construction industry is vulnerable to inflation in prices of materials. Materials needed for erecting and completing construction works could amount to about 35-45 percent of the total project cost while in some other projects, the materials cost may be as high as 60 percent.

Nwachukwu (2004) further explained that in most capital projects, materials account for more than 50 percent of their production cost. Material resources are thus the heart and life wire of any construction system. This simply means that increase in the cost of materials will affect the total cost of construction and subsequently housing supply in no small measure. Central Bank of Nigeria (CBN) (2002), stressed that inflation is a social malady as well as a pervasive economic process whose effects are felt, to some degree, by every citizen and in all sectors of the economy.
