Daniel Deng, P.E. has over 31 years of design and construction experience on highway/railroad bridges and building/facility projects. His engineering experience includes field investigation, structural evaluation, rehabilitation, and new construction. For bridge projects, Dan has performed structural analysis and design for the replacement, rehabilitation, and emergency repairs of bridge structures for single or multi-span steel, reinforced concrete, and prestressed concrete superstructures supported on spread footing, pile foundation, and drilled shaft substructures, in compliance with the standard specifications for AREMA, AASHTO, MassDOT, MBTA, and other state transportation agencies. Dan has been trained with NHI Safety Inspection of In-Service Bridges and has conducted bridge inspection and live load ratings for MassDOT and MBTA statewide. For building projects, he has performed design and construction engineering services on residential, industrial, health, and maintenance facilities for wood, steel, reinforced concrete, prestressed concrete, and light gauge metal, in compliance with the Massachusetts State Building Code for gravity, wind, snow, and seismic loads.
Edward Barwicki, P.E. has over 45 years of professional experience in the design, repair, and rehabilitation of precast and cast-in-place concrete structures, with an emphasis on large structural elements including parking garages, plaza decks, water treatment facilities, and precast concrete bridge elements. Ed has also performed numerous bridge inspections and ratings for the MBTA, MassDOT and RIDOT. When Lin Associates was charged with design for Logan Airport’s boat and tunnel roadway sections under Boston’s Central Artery master plan, Ed conceived and detailed a column slip sleeve design that enabled pile supported columns for flyover roadways to penetrate the boat construction without leaking, while allowing the boat section to move freely past the penetrating pile supported column. This unique and innovative design was accepted and subsequently implemented in numerous areas of the Central Artery construction.
