Lithos actively support the National Quality Mark Scheme. The NQMS is designed to provide confidence that work has been undertaken by qualified individuals, to recognised standards and that all legislative requirements connected to the management of the land have been considered.
All Lithos reports are completed in line with the underlying assumptions of the NQMS ensuring work is transparent, uncertainties are clearly defined, and reports undergo rigorous review.
All our geoenvironmental engineers are qualified to Degree or Master’s level and are either Chartered (geologists or scientists) or working towards Chartership.
We also have two registered Suitably Qualified Persons within the company, one who specialises in land quality, the other who specialises in geotechnical considerations, as such we can provide an NQMS declaration with reports. NQMS declarations demonstrate to Regulators and third parties that both Lithos and our clients are committed to the highest standards.
With respect to geotechnical constraints, our reports typically include consideration of:
- Depth and nature of made ground
- Presence of soft or loose natural strata
- Potential for shallow mineworkings (including coal, ironstone and limestone)
- Engineering characteristics including shrinkability, allowable bearing capacity, CBR value etc
- Slope stability
- Soakaway feasibility
- Groundwater – seasonal fluctuations, flow rates dewatering requirements etc
With respect to environmental issues, our reports typically include consideration of:
- Historic activities that could give rise to contamination
- Conceptual site model (updated as the project progresses)
- Risks to both human health and controlled waters receptors
- Gas generation & migration (including landfill gas, radon and mines gas)
- Remediation Strategy to ensure the site is rendered suitable for the intended end use and remediation is proportional to the actual risk
We have a clear understanding of planning requirements and can produce reports that satisfy planning obligations. Where development is completed under permitted development rights (including national infrastructure improvements), we consider the development in the context of other regulatory regimes, including: Waste Framework Directive; Environmental Permitting Regulations; Part IIA of the Environmental Protection Act (including feedback to Rail Operators regarding potential liabilities associated with land ownership).
With respect to site preparatory & remediation works, Lithos routinely:
- Supervise remediation activities, including treatment of hydrocarbon-impacted soils, removal of relict obstructions etc
- Supervise earthworks
- Design and supervise drill & grout of old mineworkings
- Undertake WM3 compliant waste assessments for surplus made ground soils that need to be exported to landfill
