A customer is looking to raise their existing substation distribution box structure for flood level purposes. This is a typical box structure with breakers.
New distribution breakers will be supplied that are elevated higher off ground and therefore hardware on structures need to be raised as well.
There are proposed options to either raise steel support and attachment members on existing structure by drilling and tapping existing steel to raise members and another solution proposed to move the structure off to the side and raise the elevation of the concrete foundation before placing steel back on structure.
I’ve done a few of these projects where a new elevated structure was built adjacent to existing and then everything cut over, but I’ve never heard of either of the proposed options with raising existing structure.
Anyone ever have any experience with raising existing box structure in place?
