Reducing our Environment Impact
The project involved the excavation of a 9m wide trench 1.6m deep along the full length of Colvend Street.
This trench was to facilitate the diversion of all the existing underground utilities into a designated service strip along a newly constructed footpath and to allow space on the roadway to install District Heating Pipes and to construct swales and other features.
All utilities were diverted including High & Low Voltage Power Cables, Gas & Water Mains, Telecommunication Cables and Sewers.
We identified at an early stage that we would be required to excavate and remove over 7000 tonnes of excavated materials to landfill.
This would have a significant environmental impact for everyone, as this would create over 700 lorry trips to and from the landfill/quarry.
This would not comply with the WPS Company Environmental Strategy nor would it sit well with both our clients’ Environmental targets.
A section of nearby waste ground was cleared and levelled. Mobile screening and crusher units were brought onto site.
Over 90% of the excavated materials were processed through these units which created over 6000 tonne of re-cycled type 1 & fine-fill materials, all of which were used for backfill materials after the new utilities were installed.
Carbon Footprint Greatly Reduced
Our solution negated the need for 700 lorry journeys to send 7000 tonnes of material to landfill.
Significant Cost Savings
Expensive costs of tipping and purchasing infill materials was greatly reduced.
Both SSE & Clyde Gateway were very happy as the environmental impact of completing this Project was greatly reduced.
“The recycled materials that we produced on site was of far better quality than the material we purchased from the quarry at the start of the Project prior to the major excavation works starting.”
