Inquiry #30: Are the masonry soundwalls to be built per the "Standard Plans 2018" or the "Revised Standard Plans - 04-17-20". The (2) plans are completely different structurally from each other for CMU.
Inquiry submitted 03/26/2021

Response posted 04/01/2021




Inquiry #31: Sound Wall Nos. 443 & 478 have "H" heights that are not modular for 8" CMU. SW# 443 has an H=12'-0" & SW#478 has an H=14'-0", after the barrier height of 3'-0" is subtracted from both you're left with a CMU H = 9'-0" and 11'-0". In order to build to these off modular heights, you have to use an odd 4" high unit, a 8x4x16.

Is this the intent of the state to use a 4" high unit to achieve the heights noted on SW#443 & SW#478, if so where do we place this unit, at the top or bottom? If this isn't the intent then you need to increase or decrease the wall by 4" overall and also adjust the estimated pay quantity. Thanks.

Inquiry #43: The structural plans for the Masonry Sound Walls have serious contructability issues (See Plan Sheet 439 for example). The vertical "a" bars coming out of the barrier are 8" on center and 6'8" tall. A typical 16" long block has two cells, with one end of the block open and the other end closed. On a standard wall with vertical steel 16" OC the open end of the block goes around the vertical rebar and the closed in cell goes where there is no vertical steel, only one cell has rebar. With vertical rebar 8" OC both cells would contain rebar. The only way to get the rebar into the closed cell is to lift every block 6'8" high to the top of the rebar and thread it down through the cell. This is not practical, safe, or likely even allowed by the Local Unions. We suggest reverting back to the original 2018 Standard Plan dated May 31, 2018.
