Introduction
Pre-Construct Archaeology (PCA) has been delivering high-quality, client-focused heritage services across the UK since 1993. As one of the country’s largest and most experienced providers of professional archaeology and heritage solutions, PCA is committed to executing projects on time, on budget, and with a flexible, tailored approach.
The Requirement
To uphold its high standards for workforce welfare and environmental responsibility, PCA required welfare units offering essential amenities such as a toilet, dry room and canteen without reliance on diesel fuel. Reducing carbon emissions, cutting fuel consumption, and lowering running costs were top priorities.
The Solution
ecowelfare supplied PCA with a fully off-grid, 12ft solar-powered welfare unit. This self-sufficient unit includes a canteen, dry room and toilet, providing all necessary facilities while significantly reducing environmental impact and fuel-related expenses.
The Conclusion
- Zero fuel consumption – fully powered by solar energy, eliminating diesel use entirely
- Over 76 litres of fuel saved – contributing to reduced running costs and improved operational efficiency
- More than 243kg of CO₂ emissions avoided – supporting PCA’s sustainability commitments
- Enhanced welfare for on-site teams – comfortable, modern facilities without compromise
Â
By choosing ecowelfare’s solar-powered solution, PCA reinforced its sustainability values while maintaining a high standard of care for its workforce. This unit represents a smarter, greener approach to site welfare that supports long-term environmental and operational goals.
