A new tenant was moving into a street level unit and opening a “Just Salad” restaurant.  The engineer wanted to ensure that the concrete anchors could support the dynamic load of the air handling unit.  The contractor was using DeWalt 5/8th double expansion anchors 09530-PWR.  Its important to always pull test double-expansion anchors because they have no ICC-ES approvals,  listings or accreditation.  They can very often be installed incorrectly or  installed in the wrong type of concrete.  Both of which can result in property damage, injuries or loss of life.
