Presentation 1: East Kingston Bridge Rehabilitation Using PBU’s and UHPC
By Joshua Lund, PE
This bridge rehabilitation project located on NH Route 107A in East Kingston, NH replaced a three-span superstructure over the Pan Am Railway and a residential drive in 25 construction days. The existing bridge was constructed in 1937 and consisted of shallow, closely spaced painted steel beams. Each of the three simple bridge spans are approximately 40 feet, totaling 120 feet. The bridge was structurally deficient based on the ‘serious’ condition rating of the deck.

Presentation 2: Northeastern University Spiral Stair
By Robert Champagne, PE, LEED AP, and Daniel Bard, PE
Summit Engineering was contracted by the steel fabricator DeAngelis Iron Works of Easton, MA on the design of this multi-level spiral stair. Payette, the architect of record, and Lemessurier Consultants, the engineer of record, were involved the overall building design. The stair design was provided as a deferred design submittal. Limited graphical information was shown on the original design drawings and was the basis of design for the completed structure. Summit Engineering provided all the design, modeling and calculations submittal packages for approval by the design team.

Presentation 3: Renovation of the Historic Jewett Piano Case Factory, Located in Leominster, MA
By Tom Lamb, PE
Conversion of this timber-framed mill building into Ivory Keys Apartments, a 43-unit affordable residential apartment building, included substantial structural upgrades and repairs for, among other things, a nearly 1-foot lean of the building, water damage, flood plain elevation and lateral instability issues. The project plans included foundation work and incorporating steel frames into the building to correct the lean, lateral instability, and years of neglect. In addition to structural repairs, a significant effort was made to preserve the nature of the historic mill. This included preserving the aesthetics of the exterior which included many windows.
