Contractor’s claims were in excess of $20M, including compensation for 187 unresolved change issues, time extensions and compensation for excusable delays, recovery of additional and expanded general conditions and general requirements, and pass through of discrete subcontractor claims.

After a seven-week jury trial, the jury awarded our general contractor client 97% of its claimed damages and rejected 93% of the Owner’s damages.
