Rowan Mason is an experienced construction lawyer who litigates cases and advises clients through all stages of construction. Prior to joining the firm, Rowan was a partner in Jones Day’s construction practice where he was part of the team that was awarded Chambers USA’s Construction Practice of the Year in 2017 and Law360’s Construction Group of the Year for 2020. Before Jones Day, Rowan spent several years in the renowned construction practices of the now-defunct law firms of Thelen and Howrey. He is one of three lawyers in California to be ranked “Up-and-Coming” by Chambers USA for Construction in 2021.
Rowan has represented private owners, public entities, contractors, and subcontractors in all stages of litigation and arbitration, primarily involving delay, breach of contract, and defect claims. He also has significant experience in the earlier stages of construction projects, including contract drafting and negotiation, project advice and counsel, and bid protests. Rowan’s construction experience has involved a wide range of large projects, including hotels, hospitals, oil and gas facilities, manufacturing plants, sports arenas, and heavy civil works in the United States and around the globe. Many of these projects have included disputes in the hundreds of millions or billions of dollars.
Before beginning his legal career, Rowan interned at Bechtel, where he worked in field construction and assisted the in-house legal department.
Rowan is the co-author of the Construction Chapter in the fourth and fifth editions of Thomas West’s Business and Commercial Litigation in Federal Courts and currently serves as Contributing Editor to The Construction Lawyer, a scholarly journal published by the American Bar Association
Disputes
Rowan has represented clients in domestic and international arbitrations and state and federal court. Some of his notable matters have included:
International Marine Construction Dispute
Represented the owner (an affiliate of an oil supermajor) in an ad hoc UNCITRAL arbitration arising from the largest single natural resource development project in Australian history. The dispute involved more than 100 discrete claims and counterclaims, with an aggregate amount in dispute of approximately AUD 2.1 billion (US$1.6 billion). The contractor sought recovery on the variety of bases including delay, disruption, defective performance specifications, a modified total cost claim, alleged change directives, and numerous other claims. After a six-week merits hearing in Perth in 2019, the tribunal issued an award almost completely in the owner’s favor with contractor obtaining just 3% of its original claim.
Las Vegas Raiders Stadium Dispute
Represented a specialty subcontractor on $35 million dispute with the general contractor regarding construction of the new Las Vegas Raiders stadium. The dispute arose as a result of failure in the structural steel that occurred during the lifting of the cable net roof. The dispute was settled favorably before arbitration.
Dispute on Mining Project in Peruvian Andes
Represented a leading EPC contractor in an international ICC arbitration against the owner of a $2 billion Peruvian mining project. The dispute involved over $140 million in claims including complex invoicing and audit claims, allegations that the EPC contractor had failed to properly supervise project contractors and had schemed to avoid a contractual price cap, and numerous allegations of defective engineering and construction work premised on the facility’s purported failure to meet the EPC contractor’s contractual performance guarantees. Within months of submitting the EPC contractor’s statement of defense and expert/fact evidence, the owner agreed to settle the dispute on favorable terms.
Presidio Parkway Project Dispute
Represented the design-build joint venture responsible for designing and constructing the Presidio Parkway Project, the first public-private partnership sponsored by the California Department of Transportation (“Caltrans”). The $300+ million construction project replaced the existing Doyle Drive roadway—which connected the Golden Gate Bridge with San Francisco through the Presidio National Park—and included construction of two viaducts and two tunnels. The DBJV incurred significant additional costs as a result of abuse of the permitting process and interference with design discretion vested in the contractor by Caltrans and the Presidio Trust.
Rowan assisted the DBJV in pursuing its claims against Caltrans through the dispute review board (“DRB”) process required by the contract. After Caltrans lost a number of DRB hearings and refused to accept the DRB findings, Rowan and his firm filed suit against Caltrans for declaratory and injunctive relief when Caltrans undertook efforts to frustrate the DRB process and delay consideration of the claims. After filing the lawsuit, the DBJV obtained a favorable settlement of an additional $120 million plus the deletion of certain disputed remaining work.
Golden Link Concessionaires LLC v. State of California Department of Transportation, No. CGC15546962 (Cal. Super.)
Underwater Pipeline Dispute
Represented the owner (an affiliate of an oil supermajor) in an ad hoc UNCITRAL arbitration seated in London regarding the construction and installation of a network of subsea pipelines to transmit natural gas extracted from offshore oil wells to onshore processing facilities in Nigeria. The dispute concerned thirty-eight discrete delay and extra work claims by the contractor with a total claimed value in excess of $215 million. After a two-week hearing, the arbitral tribunal rejected the vast majority of contractor’s claims, including all of the highest value claims, and awarded an amount far below the last proposed settlement amount.
San Francisco Underground Water Pipeline
Represented an engineering company in its role as a construction manager on a complex 14-party $20 million dispute regarding a large underground pipe replacement project for the San Francisco Public Utilities Commission. The engineering company, as construction manager, was sued by the contractor for allegedly failing to prevent the contractor from installing and approving defectively welded pipes. The case was resolved in a settlement on the eve of trial.
Las Vegas CityCenter Dispute
Represented the owner (MGM Resorts International and CityCenter) on disputes arising out of the $8.5 billion CityCenter development, including cost claims, delay claims and construction defects.
Perini Building Company, Inc. v. MGM Resorts International, et al., Case No. A10-612676B (Nevada District Court)
Contract Negotiations & Project Advice
Rowan has represented owners and contractors in contract negotiations for a variety of construction projects. Those projects have included contract review and negotiations for:
- The $1.6 billion Track and Systems contract on the California High Speed Rail;
- Tesla on the Nevada Tesla Gigafactory;
- A Nebraska based mining facility;
- Google fiber construction contracts in various jurisdictions;
- Numerous commercial real estate developments and hospitals in California and the southwestern states.
Bid Protests
Rowan has handled numerous bid protests on behalf of bidding contractors. Most recently, he successfully overturned bid awards by a California water board and a school district on separate construction-related projects. In both instances, Rowan was able to make compelling arguments that the agency had misled bidders and failed to comply with state and federal regulations.
