investigations to meet the project’s needs. Moreover, Langan convinced the developer that testing several sacrificial piles to geotechnical failure during foundation design would lead to overall cost savings greater than the cost of these sacrificial piles. This testing made it possible to provide a fine-tuned pile design, which was justified by tangible test results. The contractor also understood the value of field testing to justify its alternative splicing options. The alternative splices significantly reduced the amount of welding required and accelerated the construction schedule. All parties involved understood that money spent early in the project could be cost-effective if it led to an overall decrease in the project schedule. As an old proverb says, “time is money,” and time saved is money earned. The Surf Avenue development foundations were ultimately successful because all parties understood the importance of meeting the aggressive project schedule.
