A & D Quality Construction Co. LLC

A&D Quality Construction Co., LLC, is a General Contractor licensed in the State of Washington since 1991. It is owned and operated by Keith and Annette Demps, husband and wife. A&D builds residential and commercial structures and performs infrastructure services in both the private and public sectors.

Past private performance consists primarily of acquiring and developing land to build tracts of single family homes, apartment complexes, churches, and mixed-use residential/commercial buildings. A&D self-performs the majority of the work and sub-contracts the balance. Projects normally range in size from $300,000 to $3,000,000.

In addition to structural and site work, in recent years A&D has expanded services into the public works sector. The focus is on earthwork, including underground utilities construction, excavation, sewer and concrete installations, demolition, site clearing, and other infrastructure services. Projects performed include those for the Cities of Seattle, Issaquah, Renton, and the King County Housing Authority.

Proud of its safety program and record, A&D boasts an EMR rating of .90 with the Washington Department of Labor and Industries.
