Surveys were sent to over 500 producers around Iowa that had been identified as building facilities since 1990. Responses were received from 144 producers, many with information on multiple buildings. The results of the survey show that there are trends in the types of buildings being constructed but there is still a wide variety in cost and construction type. According to this survey, finishing building cost has actually dropped over the last two years, perhaps indicating changes in market pressure and construction techniques. Manures storage costs were also compared, with earth storage showing the lowest cost. For planning purposes, estimate costs that are higher than the average for each type building.
