Robert G. Campbell



Rob is among Southern California's leading construction lawyers devoting himself to the efficient resolution of construction claims disputes, primarily on behalf of owners and contractors, on projects ranging from hospitals to highways, high rises to hotels and resorts, solar to sewage treatment, and from retail to residential. 

Vindicating Owners, Contractors, And Others In Construction Disputes

Rob's clients are project owners, EPC and other prime contractors, construction managers, lenders, subcontractors, and other project participants in disputes ranging broadly in size and sophistication on both public and private works. Among the claims categories he resolves are scope of work disputes, design professional liability, delay, acceleration, disruption, productivity, lien and bond enforcement, change orders, defective work, terminations, differing site conditions, licensing, and bid protests. Rob works closely with some of the finest expert consultants in their fields and has participated in the resolution of claims involving diverse legal theories and damage recovery methodologies, including total cost and measured mile. 

An Effective Advocate

Rob works closely with project representatives and experts to evaluate thoughtfully the merits of claims and establish reasonable parameters for their resolution during constructions and project closeout, and following project completion. By attention to detail and thorough preparation, Rob draws upon his extensive experience to skillfully develop strategies to maximize the potential for early resolution of claims, through negotiation and mediation. 

When Litigation Becomes Necessary

Rob's experience includes the prosecution and defense of claims through trials in Federal and State courts, arbitrations, board hearings, and appeals. Rob also has extensive experience seeking provisional remedies to secure recoveries, such as writs of attachment, and in the collection of judgments.
