350 Mission is a LEED® Platinum-certified office building in downtown San Francisco designed by SOM. The design not only considered environmental performance goals but also community engagement as exemplified digital art displayed on the 21 metre x 11 metre LED screen within the lobby which merges with the street scape.
Dr Aldred advised on the concrete mix design for the 3 metre thick mat for the foundation system which also required a minimum early strength for removing the internally braced shoring system within 3 days of pouring the mat. He was engaged to provide recommended procedures to help address heat of hydration issues. The concrete mix incorporated 35% Type F fly ash and achieved the required performance for this elegant building as described in the San Francisco Chronicle and by SOM.
