This Design & Build project involved upgrading the existing combined sewer network with on-line attenuation to reduce the risk of sewer flooding of properties on Broomhill Avenue, Aberdeen.
The work involved the installation of approximately 220m of online attenuation pipework varying in size from 225mm to 1.2m diameter, up to 5m deep in difficult ground conditions, along busy residential roads.
It was important to maintain access for local residents throughout the course of the work on site, which involved extensive and complex traffic management arrangements.
Careful working and a proactive & pragmatic approach to design modifications were necessary to overcome the complex and congested nature of existing utility services and obstructions encountered throughout the site. In addition, flows had to be maintained through the sewer system which had to remain live throughout the duration of the works.
Close liaison was maintained with community representatives, the local council and other members of the project team, throughout, to ensure a fully compliant project was delivered with all specified requirements, whilst minimising any community disturbance and inconvenience.
GL’s close Client liaison and Project Team proficiency managed design modifications to avoid costly utility diversions and potential programme over-runs.
The overall project involves the off-site fabrication and installation of a new linkspan structure at Oban Ferry Terminal for client Caledonian Maritime Assets Ltd (CMal).
