Abstract
Principles of constructability are applied to the planning, design, and construction of drilled-shaft foundations. It is shown that the keys to drilled-shaft constructability are an appropriate site investigation, the knowledge and experience of civil engineers with drilled-foundation construction procedures, and a quality-control program. Methods of drilled-shaft construction are reviewed and specific procedures for implementing constructability during site investigations are presented. The input of engineers experienced in drilled-shaft construction is shown to be necessary for successful cost estimates, accounting for effects of construction on design assumptions, and in developing rational construction specifications, all of which are critical for applying constructability to drilled shafts. Quality control, through inspection and nondestructive testing, can increase the reliability of drilled shafts by verifying subsurface conditions and by providing evaluation of postconstruction integrity. Two case histories are used to demonstrate that constructability provides a useful management and engineering tool to reduce foundation costs and increase reliability.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
