Drilled Piers in the Piedmont—Minimizing Contractor-Engineer-Owner Conflictsby Stanley A. Schwartz, Soil & Material Engineers Inc, Atlanta, GA, USA,
Abstract: Drilled piers are used extensively in the Piedmont Physiographic Region, deriving support primarily from end-bearing on hard rock. Cost extras and contractor-engineer-owner conflicts are common because of poor design, specifications and contracts; variable subsurface conditions; uncooperative and/or inexperienced contractor personnel; and unpredictable and/or unreasonable construction monitoring demands. This paper is intended to describe these problems and present recommendations for mitigating them.
