Superior cost and schedule considerations, coupled with a high degree of design certainty (every driven pile is a tested pile) resulted in the choice of driven precast concrete piles for the hotel project.
We believe that more efficiently designed piles will help the pile driving industry flourish; however, we designers also acknowledge the cost impacts to the contractors in achiev- ing this goal. At least in the Washington, D.C. metro area, there is no one preferred or consistently less expensive deep foundation type. As such, most major building developments explore deep foundation alternatives and the least costly is often chosen.
If the pile driving industry wants to ensure its active par- ticipation in today’s building market, cost needs to be a part of the equation and efficient pile designs help this endeavor. We encourage more dialogue on this topic within the industry to ensure broad support of driven piles between geotechnical designers and contractors.
