Engineering consulting for Ghana and Africa: civil, coastal and marine engineering, dredging, geotechnical and hydrology work, impact assessment and contamination remediation — delivered by experienced teams who work where conditions are hardest.
Polluted lagoons, silted channels, flood-prone catchments, reclaimed land and legacy contamination do not forgive guesswork. The ground, the water and the environmental regulator all have to be understood before any foundation is poured.
Noxy provides the engineering and environmental evidence that investors, lenders and regulators need — and the delivery teams to act on it.
Most delays on waterfront and brownfield projects trace back to ground, water or environmental unknowns discovered too late.
Roads, bridges, drainage, utilities and site infrastructure from feasibility through construction supervision.
Sea defences, breakwaters, marinas, inlets and outlets, designed against tides, waves and erosion.
Bathymetric survey, dredging plans, sediment management and reclamation design.
Ground investigation, foundation design and settlement analysis for soft, reclaimed and made ground.
Catchment modelling, flood risk, tidal flushing and flood-control systems.
Environmental and social impact assessments, management plans and regulator engagement to lender standards.
Site characterisation, risk assessment and remediation of contaminated silt, soils and legacy industrial sites.
Sewage treatment upgrades, solid-waste management, recycling and waste-to-energy options.
Our engineers and environmental scientists are selected for hands-on experience in tidal, polluted and congested conditions. They are registered professionals who stay accountable on site, not only in the report.
Experienced civil, coastal, geotechnical and hydrology engineers with senior leads who own each deliverable.
Scientists and safeguards professionals who meet national and international lender requirements, including community engagement.
Survey, sampling and supervision crews trained for hazardous, contaminated and marine working conditions.
Surveys, ground investigation, sampling and baseline studies to remove unknowns.
Engineering options, flood and hydraulic modelling, ESIA and risk assessment.
Detailed design, permitting and remediation strategy ready for tender.
Construction and remediation supervision, monitoring and close-out reporting.
Ground, water and contamination risk quantified before capital is committed
Environmental approvals on the critical path, not behind it
Accountable senior engineers from investigation through supervision
Tell us about the site and its history. We will outline the investigation, engineering and environmental path to a bankable design.
Start the Conversation →Yes. We characterise contamination, assess risk and design remediation, including treatment and management of contaminated silt, soils and legacy industrial sites.
Yes. We prepare ESIAs, management plans and stakeholder engagement to national requirements and to international lender and ESG standards.
Bathymetric and sediment surveys, dredging and reclamation design, sediment testing, treatment and disposal strategy, and supervision of the works.
Yes. We model catchments and tidal conditions and design drainage, tidal flushing and flood-control infrastructure, linked into smart monitoring where required.
