Bi-Modulus Columns (BMC’s) were identified to provide the ideal value-engineering solution, providing an improved ground bearing capacity with minimal spoil. To prevent surface disturbance (i.e. ‘egg-box deformation’) across the final pavement, the compacted granular BMC head along with an overlying granular load distribution mattress was sufficient to offer a 1.8m of coverage above the concrete element. The alternative would have required the Main Contractor to have carried out a considerable reduced level dig to remove around 1.8m of unsuitable material across the whole of the site- both costly and time consuming.
