The Department of Public Works and Transportation has developed the following:
- Standard Specifications for Construction and Materials
- Standard Details for Construction
- Commodity Code
- Design Manual
Committee Meetings
A committee meets on a regular basis to propose changes to these documents as necessary or appropriate. The adopted specification book is available online. 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.
Addendums
Addendums are 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, Towson, Maryland, 21204. You may call 410-887-3531 for further information.
