Source of Supply

The Division of Construction Contracts Administration (DCCA) is responsible for monitoring the materials supplied and is empowered to disapprove suppliers at any time. The approved Source of Supply (PDF) list will be published with additions, changes and deletions as needed. Materials must be made by approved manufacturers, and may be supplied by either approved manufacturers or approved suppliers. 

Use of this list must conform to the following General Provisions in the Standard Specification For Construction & Materials:

GP 6.01 - Control of Materials

If all materials are to be supplied from the sources on this list, only written notification to the effect is required. If other sources are to be used, they shall be submitted for approval. It shall be the Contractor's responsibility to insure that all materials are supplied from approved sources. Once the source of concrete or bituminous concrete for exposed final surfaces has been selected, that source is to provide material for all construction of continuous surfaces on the entire project. Submittal of all sources of supply will still be required for projects involving State and Federal funding. The engineer will inform the contractor as to source acceptability as soon as possible.

Note that:

  1. All types of pipe are grouped under the pipe category;
  2. Waterline and appurtenances section has been added specifically for waterline construction.
  3. Portland Cement Concrete suppliers and bituminous concrete suppliers must maintain an approved mix design with DCCA;
  4. Any change of plant or mix for bituminous concrete or Portland Cement Concrete surface course for a paving project or Portland Cement Concrete for exposed surfaces is not allowed without the specific approval of DCCA;

Errors or inconsistencies can be reported to John Koneyak at 410-887-8729 or jkoneyak@baltimorecountymd.gov.

Questions regarding sources of supply for specific projects may be directed to the program manager for that project at 410-887-3531.
