“!Caution! Sub-marine BART Tube Area of Special Handling". Above this call out, a note indicates "See Section 35 20 23 Dredging, Paragraph 3.2.9".

Should there be language in the Specifications that addresses the BART Tube or special handling near it?

Reference to Section 35 20 23 on the drawing will be removed. Amendment forthcoming.

The information that is provided on the drawing is sufficient to inform the Contractor regarding the location and depth of the tube.
