Keith Demps

A&D Quality Construction

Keith and his wife were both raised in the construction business and, perhaps fittingly, their union led them to the real estate development business. In 1991, Keith and Annette Demps founded A&D Quality Construction Co., LLC., a Seattle-based general contracting firm.

A&D offers infrastructure services in both the private and public sectors, as well as tenant improvements to specialty construction projects. They have more than 30 years of experience in construction, building renovation, maintenance, and repair projects. Keith and Annette Demps has been instrumental in building A&D’s reputation for providing the highest quality service while successfully meeting budget and schedule demands. The company has completed projects ranging from $300,000 to $3,000,000, including single-family homes, apartment complexes, churches, and mixed-use residential/commercial buildings.

A&D offers additional services to meet the unique needs of the clients, including veterans, the differently-abled, and special needs children. Ramps, wider doors, and customized bathrooms that can accommodate a wheelchair can help the physically challenged, and Annette takes that need very seriously.

Recently, A&D expanded its services into the public works sector. Their self-performing scopes consist of demolition, excavation, clearing, grading, concrete, underground utilities, and tenant improvements. A&D has completed projects for the Federal Aviation Administration, U.S. Army Corps of Engineers, Sound Transit, Bonneville Power Administration, and several others. A&D currently can bond single projects in excess of $4,000,000 with an aggregate of $5,000,000.
