Project: Biogas Energy Plant

Woolwich Bio-En produces green, low cost, renewable energy from the anaerobic digestion of organic waste. Frey Building Contractors was selected to construct this 2.85 Megawatt biogas energy plant. Through a process of fermenting biomass and other garbage, the plant produces methane gas which is used to generate electricity and usable heat. This project was delivered with a combination of Time and Material, Fixed Price and Construction Management contracts. The scope of work also included providing working drawings. The technology for the plant is European, and Frey was tasked with sourcing materials and methods that could be acquired locally. Of particular concern was the material used to construct the digester tank and treatment tanks, because the environment in the tanks is extremely corrosive. The components of this construction project included; heat and power building, process building, pre-treatment tanks, digesters, repository tank, truck filling pump house, fire reservoir and truck scale. The plant processes 70,000 tonnes of organic waste per year, and operates 24 hours a day with only 5 employees.

Our firm has worked with Frey’s for over 25 years. We consider Frey to be a contractor of choice for their high quality of workmanship, their dependability and their distinguished ethical standards. Several projects with Frey have been high quality agricultural facilities. Additionally our experience with Frey’s includes large industrial and commercial projects, which demonstrates the broad experience and capabilities of their company. Overall, we find the management, in-house design staff and site personnel of Frey Building Contractors to be a pleasure to work with, and we are proud of our association with their firm.
