Standard Specifications and Details

The Department of Public Works has developed Standard Specifications for Construction and Materials and Standard Details for Construction. They are incorporated into our construction contracts by reference.

A committee meets on a regular basis to propose changes to these documents as necessary or appropriate. A draft of these proposed changes are available on-line for comment.

An Addendum is issued when a sufficient number of these adopted changes are accumulated.  They can be purchased from our Division of Construction Contracts Administration, 111 West Chesapeake Avenue, Room 300B. You may call 410-887-3531 for further information.

Changes made by the committee but not yet incorporated into an addendum are included in proposal books for construction contracts advertised for bids. These changes are available for engineers to incorporate into contract documents being prepared for advertising.
