Title: RESEARCH PAYS OFF: NCDOT'S EXPERIENCE WITH PREDESIGN LOAD TESTING

Availability: Find a library where document is available Abstract: In 1994 the North Carolina Department of Transportation (NCDOT) initiated an in-house research project on load testing in the predesign phase of a project. The first pilot project was the Neuse River Bridge. A load test program was developed and managed in house. The test results indicated that initial subsurface exploration information was inaccurate. With the corrected subsurface information it was possible to reduce significantly the drilled piers' embedment lengths without compromising the required load capacity. The refined design parameters resulted in large savings. The cost of the load test program was $310,000; the resulting estimated savings totaled $10,500,000. This article discusses the reasons why this research project was initiated, how the experience gained from this project was subsequently applied and the benefits that resulted.
