Leader of East Coast operations for Nossaman’s Infrastructure Practice Group, Simon J. Santiago handles development, procurement and construction issues for the largest transportation, transit and multi-modal projects in the U.S.  Public sector clients seek his guidance in creating successful infrastructure projects through innovative procurement, financing and delivery methods including public-private partnerships (P3s).

Given his broad experience, he often advises industry leaders and policymakers on emerging federal legislative and policy issues involving transportation.  At the state level, Mr. Santiago helped develop P3-enabling legislation, procedures and programs in Georgia, Maryland, North Carolina and Virginia.  He also counseled the Pennsylvania Turnpike Commission and the Port Authority of New York and New Jersey on state and federal law governing all-electronic toll systems.

Before joining Nossaman in 2006, Mr. Santiago was a litigator with a construction and government contract law firm in Northern Virginia, where he advised public- and private-sector clients on disputes involving large and complex infrastructure projects.  He also served as a judicial clerk with the General Services Board of Contract Appeals, assisting in legal analysis of contract claims and disputes.  This collective experience has helped him anticipate potential risks and adjust procurement and contracting strategies accordingly.
