Project Scope
Teaming with Kinsley Construction’s Materials, Site and Industrial crews, our Highway & Bridge team replaced this structurally deficient dam in six phases spanning several years. Throughout these phases, our scope included:
Clearing
Installing an access road
Demolishing a pier and bridge
Excavating soil and rock
Installing a cofferdam
Demolishing the existing concrete spillway
Constructing a new labyrinth spillway
Installing 44,000 cubic yards of roller-compacted concrete (RCC) gravity dams
Installing training walls, and channel armoring
Modifying embankments and armoring existing with RCC
Constructing a new outlet works facility adjacent to the principal spillway
Installing a permanent stream crossing and concrete weir structure for stream flow monitoring
Installing a new pre-fabricated electrical building and performing site electrical work
Installing an automated instrumentation system
Installing post-stormwater management facilities
During Phase 1 of this project, our Industrial Division completed the following work:
Installing an access road and temporary water barrier
Removing soils and sediment from the existing outlet pipe opening and headwall
Completing concrete modifications to enclose the existing headwall
Fabricating and installing stainless steel liners in the newly enclosed headwall
Removing sections of the existing dam and installing cast-in-place concrete grade beams to the top
Fabricating and installing galvanized steel platforms, which cantilevered from the existing pedestrian road over the dam
Installing sluice gates, operator stems and trash racks provided by York Water Company
This project is a recipient of Central Penn Business Journal’s Top Project Award for 2025.
