Construction Case Study
Noise control during vacuum excavation at Durham Uni
Durham University's 10 year strategy calls for major developments across the estate. As part of the University's development plans, a project to undertake excavation work for new nodes and ductwork for data installations was required. The excavation work was located within Durham's busy and historic city centre, on a narrow, cobbled residential street, where a high degree of public access was required.
Given the context of a busy public setting, only a limited time period was permitted for road closure. This, along with the extensive presence of existing utility services and cabling within the ground, meant that contractors had to carry out the works using a vacuum excavator. This approach allows the use of suction to remove all the debris created, and enables the safest means of locating underground utilities, but does generate excessive noise, which was particularly problematic when working in such close proximity to the general public.
