''The client was pleased with the substantial cost savings and time due to Keller's alternative design.''

Bahrain International Airport - Modernization Program

The project

The airport modernization program includes a new 20-year airport masterplan including the construction of a new passenger terminal in addition to the expansion and refurbishment of the existing terminal. The initial expansion phase is expected to increase the airport's capacity from 9 to 14 million passengers per year.

The challenge

The project consists of the design and construction of 5,469 cast in-place Bored Piles ranging from 500mm to 1050mm diameter and 20m to 24m in length. The main challenge was to install the piles on a restricted site without disrupting any of the radar and the arrival and departure flights while working in and around the terminal. At the same time, unmarked underground services needed to be identified and re-routed by other subcontractors to clear all piling locations.

The solution

Keller’s alternate design with varying diameter and shorter lengths successfully passed the preliminary pile load tests. The client was pleased to adopt Keller's alternate design which reduced the cost and delivered an early project completion.
