Pushing technical boundaries in support of creative achievement
Greenwold & Co. was founded in April 2012 by David J. Greenwold, PE. Mr. Greenwold’s experience includes a wide range of consulting services and bridge types, including conceptual and detailed design of a number of iconic multi-use bridges. Since earning his MS from MIT, he has been rooted in the Boston area, most recently serving as Principal Engineer of Ammann & Whitney's Boston operations. Mr. Greenwold is supported by a small network of highly experienced consultants. Our work is focused on the design of special structures.

North Bank Bridge
Boston and Cambridge, MA Highly irregular 700 foot long steel truss bridge. The trusses sweep above and below the deck in response to the site constraints, including commuter rail tracks and the Millers River. To control vibrations, the structure has a fiber reinforced polymer (FRP) deck made composite with the steelwork. Conceptual design was done in collaboration with Buro Happold and Julian Hakes. This project was presented by Mr. Greenwold at the 2011 International Bridge Conference and at Footbridge 2011. The bridge was published in the proceedings of both conferences as well as in Bridge Design & Engineering magazine. Role: Principal Engineer with Ammann & Whitney More... |

Weave Bridge
Philadelphia, PA 145 foot long single span steel truss with scissored top chords. The structure is principally composed of steel "ribbons" wrapped around the rectangular user space. The structure was conceptualized by Cecil Balmond of Arup’s Advanced Geometry Unit. Role: Internal Consulting Engineer with Ammann & Whitney |

West End Bridge
Pittsburgh, PA Winning entry for an international design competition. Two 700 foot long curved pedestrian bridges were proposed to be hung from an existing trussed arch bridge. The existing bridge was built over the Ohio River in 1932 and is listed on the National Register of Historic Places. The attachment was to be made with stay cables extending from one edge of the new decking up to the existing arch. The new structures were to be an iteration of the relatively recently developed "ring cable" structural scheme with a large leap in maximum span length. This proposal was a collaboration with EndresWare. Role: Project Engineer with Ammann & Whitney |

Liberty Bridge
Greenville, SC 350 foot long pedestrian bridge over the Reedy River. The single suspension cable carries a highly curved deck to which the hanger cables are attached on only one side. The resulting torsion is countered by a ring cable which follows the deck curvature and is located below the deck. This bridge received several awards:
