Spriggs Excavation, Inc. expanded a substation for Xcel Energy near Denver, Colorado, in December 2024. The scope included demolishing existing fencing and structures, stripping topsoil, performing cut-and-fill operations, excavating a detention pond and coordinating concrete pours for a stormwater trickle channel. The project entailed moving more than 12,000 cubic yards of dirt on-site and exporting over 30,000 cubic yards off-site. Spriggs delivered all civil scopes, including a new perimeter fence, expanded the site entrance for safe truck access along a busy highway and integrated daily with live substation operations around underground and overhead utilities. These unique challenges required daily precision and adaptability.
