Discussion of ‘precision leveling at the White House’

Abstract

The author has given an interesting and enlightening account of the difficulties met in keeping accurate levels on a site which is being used for construction operations. He and his assistants are to be congratulated on the patience and ingenuity they showed in carrying their job to a successful conclusion. From the nature of the work described in the paper, it is evident that the expense involved was by no means negligible. The author was fortunate that in this case the size and public importance of the White House project ensured that the necessary funds were provided, once the need for keeping accurate level records was recognized. On less important construction jobs, the cost such a task is often a stumbling block, even when the resulting records might be considered an essential part of good construction practice. Certainly the obstacles reported in the paper are not encouraging to anyone planning similar work with limited funds at his disposal.
