PROJECT NAME: HOTEL AVIA, LONG BEACH, CA

Hotel Avia is located in Long Beach about 2 blocks from the water. The soil is sandy, becoming very dense about 40 feet below existing grade. The original design was for 24 inch CIDH Piles 60 ft deep. We offered a value engineering design using displacement piles that saved about $1.5 million on the foundation system.

The piles required design loads of 210 KIPS in Tension and Compression, 30 KIPS Lateral, with testing to 2.5 times design load.. We submitted a design using a 45 ft long, 16 inch displacement pile with a #20 Grade 75 KSI steel bar full length and a 15 ft long cage utilizing 4 #6 vertical bars.

We installed the piles using a BG28 drill rig equipped with a computer that monitors torque, crowd, concrete pressure, time, depth, and penetration resistance. All 217 piles were installed with very few problems.
