What Is Marine & Pier Demolition?
Marine & pier demolition encompasses the safe removal of any waterfront or in-water structure—docks, piers, bulkheads, boat launches, and floating platforms. Rocky Demolition uses barged excavators, crane-mounted shears, underwater cutting techniques, and debris-recovery barges to dismantle these structures with minimal disturbance to water quality, shoreline habitats, and ongoing operations.
When to Choose Marine & Pier Demolition
| Scenario | Application |
|---|
| Aging wooden timber docks | Remove decayed pilings and decking to install new structures |
| Concrete boat ramp replacement | Demolish existing ramp slabs with diamond wire & abrasive-water cutting |
| Floating barge platform removal | Lift and haul away floating structures in marinas or industrial docks |
| Bulkhead & seawall deconstruction | Sectional removal of concrete or timber bulkheads along shorelines |
Our 6-Step Marine & Pier Demolition Process
Pre-Demo Survey & Permitting
– Hydrographic survey, habitat assessment, coordinate with state wildlife & water agencies.
Barge & Equipment Mobilization
– Position barges, floating cranes, excavators, and dive support vessels.
Environmental Protections
– Deploy turbidity curtains, silt fencing, and oil-absorbent booms to safeguard aquatic life.
Structural Dismantling
– Use crane-mounted shears, concrete saws, and underwater hydraulic tools for precise cuts.
Debris Recovery & Site Cleanup
– Lift debris onto recovery barges; perform underwater sweep with divers and grapples.
Final Inspection & Restoration Prep
– Verify water-quality standards, remove all equipment, and hand over site for reconstruction.
Specialized Gear & Technology
Marine-Rated Excavators & Cranes: Mounted on floating barges for above-water demolition
Underwater Hydraulic Shears & Crushers: Diver-operated for submerged structure removal
Diamond Wire & Abrasive-Water Saws: Cut thick concrete ramps and bulkheads under water
Turbidity Curtains & Oil-Boons: Contain sediment and hydrocarbons during work
Recovery Barges & Crane-Tugs: Safe collection and transport of debris to shore
Cost Drivers & Pricing Range
| Factor | Low | High |
|---|
| Structure Type | Small timber dock (<500 ft²) | Large concrete pier (>5,000 ft²) |
| Water Depth | <5 ft shallow shoreline | >20 ft deep reservoir sections |
| Environmental Control | Standard turbidity curtain | State/Federal endangered‐species monitoring |
| Access & Logistics | Boat launch access | Remote canyon or private lakefront |
Permit & Local Compliance
| Jurisdiction | Requirement | Rocky’s Role |
|---|
| Colorado DNR – Waterways | 401/404 water-quality permits & wildlife notifications | Prepare applications & coordinate agency inspections |
| Local County Conservation | Shoreline disturbance permits | Install erosion controls; file monitoring reports |
| EPA & CDPHE | Spill-prevention & debris-containment plans | Deploy spill kits, turbidity barriers, and booms |
| U.S. Army Corps of Engineers | Section 10/Section 404 permits for navigable waters | Draft and submit permit packages |
Disposal & Recycling
| Material | Outcome |
|---|
| Timber Pilings & Decking | Clean wood → mulched or repurposed for landscaping |
| Concrete Ramps & Bulkheads | Crushed on shore → used as aggregate or riprap |
| Steel & Hardware | Sorted & recycled at regional scrap facilities |
| Mixed Debris | Segregated → safe disposal of non-recyclables |
