McKissack assisted DC Water in constructing a new biosolids facility to help lower biosolids quantities and provide renewable electricity.
The first project of its type in the United States, the plant helps control the amount of biosolids taken to landfills each year and reduce the carbon footprint of the entire facility by allowing the plant to generate its own electricity from low gas British thermal units. McKissack was responsible for architecture, site/civil, design, permitting, hydraulic engineering, preparation of project drawings and specifications, progress inspections, and constructability reviews. McKissack also performed construction phase services, including shop drawing, Requests for Information, and change order reviews.
