  • Lead counsel for national general contractor client in complex litigation on the Nexus high-rise condominium project. ACS brought claims against the Owner for foreclosure of its construction lien, breach of contract, breach of duty of good faith and fair dealing, and quantum meruit. 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. Owner withheld compensation of contract balance and brought numerous counterclaims seeking recovery of liquidated damages in excess of $4M, as well as other contract and tort-based damages. We successfully dismissed Owner’s tort claims and limited Owner’s recovery through summary judgment motions prior to trial. Notably, we used key contract provisions to obtain a ruling prior to trial that Owner could not assess liquidated damages for periods of insured delay. The case was tried virtually for 7 weeks/28 trial days before a 12-person King County Superior Court jury, which awarded our general contractor client 97% of its claimed damages and rejected 93% of the Owner’s damages. The jury found that the Owner breached the contract and the duty of good faith and fair dealing and that quantum meruit was proven. Post-trial, we obtained judgment on the jury verdict , foreclosed the lien, and obtained an award for our client’s attorneys’ fees, costs and expert expenses resulting in a final judgment against the Owner in excess of $30M. Due to our timely recording a lien in advance of any unit closings and resulting bonding of the lien for all sold units, the judgment was promptly collected from the lien release bond surety and Owner pending the Owner’s appeal of the judgment. ACS will defend the massive jury award through appeal. The following links provide additional information on this tremendous result for our client.
  • Lead counsel for General Contractor client in $50 million AAA Arbitration against Project Owner involving hospital expansion in Texas. During construction, an explosion occurred that destroyed a portion of the completed work. Insurance policies were in place that covered the losses and rebuild efforts, yet the Owner refused to pay the Contractor for the work performed and sought to hold the Contractor responsible for the explosion and Project completion costs incurred when the Owner hired a new contractor to finish the Project. After a two-week hearing conducted via Zoom, the Arbitration Panel awarded the Contractor the entirety off its requested contract balance, change orders and attorneys’ fees and rejected all of the Owner’s claims that were in excess of $40M.
  • Lead counsel for general contractor pursuing $5.3M in disputed billings and change orders and defense of $16.7M defect and delay/liquidated damages claims asserted by Owner.

The general contractor was awarded in excess of $5.8M in attorneys’ fees, expert fees and costs, resulting in a net judgment in the General Contractor’s favor of $9.6M. ACS successfully represented the general contractor through appeal, with the jury verdict affirmed by the Supreme Court of WA
