For situations not covered by these documents, consult an MBTA project manager for further information.

Note: Standards are evaluated and updated on an ongoing basis. Every attempt will be made to include updates in the Directives section. It is the design consultant’s responsibility to ensure the latest standards and requirements are used. Where conflicts exist, typically the most stringent requirement applies.
