  • Conducted a deck condition evaluation to assess various deck reconstruction alternatives
  • Established destructive and non-destructive testing protocols, including: deck coring and testing, delamination survey, half-cell testing, and pachometer testing
  • Prepared MPT plans considering high traffic volumes entering and exiting LaGuardia Airport. MPT plans considered the following: multiple stage construction, construction staging, detours, lane shifts, traffic signing, and an accelerated construction schedule
