Description of Professional Services
Hall's Pond, a 15 acre impoundment, is used by Charlestown, New Hampshire to augment the Town's primary municipal water supply. The dam was overdue for an upgrade to ensure continue safe operation. DuBois & King's water resource engineers were retained to provide assessment and design services.
D&K Service Highlights
- Phase I: site inspection, filed survey, subsurface exploration, hydrological/hydraulic analysis, conceptual design of repair alternatives, summary report to the Town.
- Phase II: design of selected rehabilitation alternative – a new stand-alone concrete gravity dam (230 feet long and 8 feet high) poured against the existing wall, construction documents, cost estimates.
Of note:
By leaving the existing dam wall in place and pouring the new concrete against the old wall the Town realized a significant savings in construction costs. Back to Top
