As Principal Contractor John F Hunt was required to demolish and remediate a former paper mill, comprising a large number of tightly arranged structures, pipelines, ducts, pits and soak-aways in addition to a large culvert that ran beneath the site.
The former paper mill straddled a major river (River Culm) and had had heavy industrial usage dating back to the 1800s. The river ran through a large culvert (pictured right) for almost the entire length of the site.
Significant pollution issues were present with contamination in the form of heavy and light hydrocarbons and asbestos in the soils.
The remediation of the contamination around the culvert presented a significant problem. Our solution was to construct a temporary river diversion to allow the culvert and surrounding ground to be effectively remediated without risk to the River Culm.
