Plumber cut pool grid ground

[highendtron]

A portion of the walk had to be removed for the plumber on a commercial pool. The plumber cut through the grounding grid. After the plumber fixed his run they called me and wanted me to cad weld the grid back. I thought that the grid could be put back together with direct burial ground connectors. Code references would be appreciated.
