Eastwood have carried out civil and structural design, contract administration, principal designer duties, and site investigation services on this multi-phase development for over seven years.

Beginning in 2015, the primary objective was the development of a comprehensive earthworks, remediation and surface water drainage solution to facilitate the re-development of the former colliery, located within a highly industrialised area.

As the project progressed, the team experienced numerous site-specific challenges across the highly contaminated site. It required mitigation through enhancing existing foundation techniques, complex drainage systems and sustainable design approaches, whilst also compelling the technical team to develop and implement innovative construction methodologies.

To meet strict planning guidelines beyond the specification of traditional solutions, the technical team developed a unique, durable, sustainable drainage system (SuDS) that could accommodate surface water run-off for a critical 1 in 100 year storm water flooding scenario. This was done whilst also developing a flexible solution to effectively manage unpredictable environmental conditions, resultant from climate change.

In addition, the team sought to integrate at least two treatment trains, within the surface water discharge prior to entry into Rossington Drain, to remove pollutants and mitigate contamination of the watercourse.
