Note 6 applies to the localized areas around the repairs on the outside of the cap. The inside of the cap will be cleaned and painted along with the entire structure as per note 15 on sheet 19 of 43.  
Question Date: 5/15/2019 10:37:21 AM
Please reference VDOT response to Clean & Paint Pier Cap Beams question on 5/14/19. This response references note 15 on plan sheet 19 and goes on to say paint “the entire structure” in accordance with this note. This note 15 specifically references project specifications for the bent cap and brackets, which includes sandblasting requirements. We believe the intent is to paint all the steel bent caps per special provisions and to recoat the entire remaining steel structure (girders, cross braces,…) in accordance with standard specification. Please advise if this is a correct assumption, if not, please provide specific clear guidance as to the limits of this work, as this is a significant cost item.  
Answer   Date: 5/17/2019 4:41:51 PM
Note 6 on Sheet 19 pertains to repaired areas and needs inspection/approval by the engineer. Note 15 pertains to the recoating of the entire structure (girders, bent caps, cross frames, etc.), which is listed as a bid item on Sheet 2: Recoat Existing Structure (Str. No 2855). This bid item is covered by Sec. 411 of the specifications.

Answer   Date: 5/14/2019 2:51:48 PM
