ACES Completes Oman Highway Pile Testing Work

ACES Pile Testing and Instrumentation (PT&I) Regional Center of Excellence has completed an extensive pile testing and instrumentation program for the Bidbid Sur highway (Section 1) in Oman.

The Bidbid Sur project consists of the expansion of a 75km section of a road from a single, two-lane carriageway to a four-lane dual carriageway highway and includes nine crossings with bridges, one underpass, four overpasses and a 50km service road.

ACES scope of work consisted of 1,000 pile integrity tests, 580 cross-hole sonic tests, and 14 static load tests to a capacity of 700 tons.

One of the main challenges faced by ACES was the difficulty in transporting static load blocks and beams due to the mountainous and rugged area along the roadside. As an alternative solution, the ACES team suggested utilizing bi-directional static load testing, which was conducted successfully at six locations (tested to a capacity ranging from 615 to 3,000 tons). The bi-directional test is an innovative method to test high capacity piles through hydraulically driven, sacrificial loading device installed within the foundation unit. As the load is applied to the device, it begins working in two directions; upward against upper side shear and downward against base resistance and lower side shear.

ACES PT&I Center of Excellence is one of the pioneer centers in the region in pile testing and instrumentation and offers a wide array of technical services including but not limited to pile integrity, caliper logging, static load testing, high strain dynamic load testing, and bi-directional static load testing.
