In March 2019, Van Elle was awarded the contract by BAM Nuttall’s HEP team to help on the Don Viaduct Bridge Strengthening in Aberdeen, originally built in 1880.
The project was to install piles that would form part of a new shock absorber anchorage assembly that will allow the Don Viaduct to remain in use for many more years to come. The schedule of works included the installation of 32 no. 762 mm Spliced Circular Hollow Section (CHS) piles to a depth of 10m (infilled with reinforced concrete) using one wheeled T10,000 Colmar RRV and one tracked T10,000 Colmar RRV equipped with one MOVAX SG-60V and one MOVAX SG-65 as well as a 2.5 tn BSP impact hammer.
The project presented opportunities for the business to unearth innovative solutions through joined up thinking across divisional disciplines to solve issues as they emerged. Working in collaboration with their Specialist Piling team, finally 40 no. working piles (10 no. x 4 corners of the Don Viaduct structure) were installed in the middle of May 2019, around 7-10 days ahead of published schedules. The technical knowledge and experience proved to be pivotal in the final solution delivered in this prestigious project.
Several commendations have been received from the client, thanking Van Elle for a successful program of works, which has given BAM Nuttall the best chance of succeeding in an on-time delivery of the next phase of the HEP.
