A permeable paving system was incorporated into the external works, providing both the required parking and pedestrian areas while contributing to the sites’ surface water management strategy. Surface water is managed through a below-ground attenuation system, with the drainage network designed to collect and attenuate runoff before
discharge from the site.
The structural design was informed by the site constraints. Timber roof trusses were adopted, providing an efficient structural solution while maintaining the required internal layouts for the individual
occupiers. The proximity of the retaining walls to be building
foundations presented a challenge, with the structural arrangements
developed to coordinate the retaining structures, foundations and
below ground drainage.
A review of available mining records identified shallow historic mine
workings, resulting in the requirement for specialist grouting works.
During construction, an unexpected mine shaft entry was also
discovered.
Following consultation with the Coal Authority, the shaft
was subsequently treated and capped, allowing the development to
proceed.
