2026 ACEC-NH & NHDOT Technical Exchange Conference

Session 9A: Greg Lake Dam Rehabilitation, Antrim, NH
Speakers: Appalachia Kunz, Nathan Nesbit, Diana Eliasson, & Nick Swanson, UNH
- UNH Capstone Team 14 has collaborated with The Turner Group to evaluate the rehabilitation of Gregg Lake Dam in Antrim, NH. Inspectors from the NHDES Dam Bureau have raised issues regarding the condition of the high hazard dam, noting inadequate freeboard during design storm events, inoperable gates, deteriorated concrete, and unknown embankment stability. The team will present the existing conditions analysis and potential mitigation techniques for the hydraulic, geotechnical, structural, and site components of the project.

Session 9B: NH Route 28 Wolfeboro (South Main Street) Roadway

- The NHTI Team shadows the NHDOT Wolfeboro 29615 project that proposes improvements to South Main Street (NH 28) in Wolfeboro, NH. The semester‑long roadway design project studies roadway design topics including - geometrics, pavement design, drainage, traffic analysis, safety, and pavement design – following the project development process from preliminary to final design. The project goal improves pavement and drainage conditions, as well as mobility for all users, while reviewing environmental conditions and requirements. The Team will present the existing conditions, design criteria, potential concepts using AutoCAD Civil 3D, and actions anticipated to complete the design by semester end.
