Discussion and possible action on AB-023: Tower Crane Site safety Plans

Draft #2 of AB-023 is discussed.

Title: “Tower Crane Site Safety Plans”  is discussed. One suggestion is to change it to “Tower Crane Site Safety Plans attached to DBI permit for attachment and foundation.”

It is noted that DBI does not issue permit for tower crane, only for attachment and foundation.

Definitions:

2c and 2d:

Mobile cranes and self-erector, not  foundation oriented, are exempt from the requirements of this AB.

Item 7 of the AB on DBI’s requirement for crane inspection certificate should be rephrased to something like: “evidence of operation submittal”, or documentation that begins process with CAL/OHSA.

DBI also would require location of crane on the street drawings, design loads, designated load areas and storage areas.

Item 8 of the AB:

(1)     Civil Engineer licensed in the State of California need to evaluate adequacy of tieback  (i.e. crane attachment)  to building.

(2)     Civil Engineer licensed in the State of California  and  Special Inspector need to verify that building is up to strength to receive the  crane loads.
Civil Engineer licensed in the State of California   need to specify design strength of concrete at each attachment , to be verified by Special Inspector.

To ensure the continuity of high level CAL/OHSA oversight , good crane procedures and good guidelines in Title 8 are in place.

Action item is to revise AB-023 to incorporate recommendations from meeting between DBI, CAL/OHSA and crane contractors on 6/26/08 and to return to this subcommittee for review.
