The number and type of signs required will be determined by the project's scope, visibility, and impact to the NIH campus. The construction contractor shall submit a signage plan to the project officer for approval.
 
The construction area shall be well marked with signs that both notify and protect the general public. No portion of the signage shall extend into the walkway.
 
Sign posts for 'project signs' shall be fabricated from 4"x4" pressure treated wood posts.
