Economy in reinforced concrete construction

WHEN our energetic Secretary suggested, I should read a paper before the Concrete Institute, it was with a certain amount of misgiving that I agreed to his suggestion, as I had not a vast amount of spare time in which to write anything, and I was inclined to think that many, if not most, of you know more about the subject of Economy in Reinforced Concrete than I do. Still there may be some, to whom some of the information is fresh, and the paper may help by discussion to bring forth from the members of the Institute points of economy which are unknown to all of us, and so I trust, that it will prove of some benefit to the Institute.
