Infrastructure You Can’t See Still Needs Regular Inspection
Piers deteriorate. Water intake pipes corrode. Dock pilings rot from the inside. Seawalls shift and crack. If you wait until problems are visible above the waterline, you’re already looking at expensive emergency repairs instead of planned maintenance. Regular underwater inspection identifies issues early — when they’re still fixable at reasonable cost.
⚠️ The Cost of Deferred Underwater Maintenance
A failing pier piling discovered during an inspection might cost $2,000–5,000 to replace on a planned schedule. The same piling discovered after catastrophic failure — when the dock collapses or becomes a safety hazard — can cost $20,000–50,000+ in emergency repairs, liability exposure, and regulatory fines. Early detection through regular inspection is always the cheaper path.
Infrastructure We Inspect
🏗️
Piers & Docks
Complete underwater inspection of pier and dock infrastructure — pilings, footings, bracing, decking supports, and structural connections. We identify rot, corrosion, shifting, and damage before they become safety hazards.
- Wooden piling condition and rot assessment
- Steel piling corrosion and section loss
- Concrete footing integrity and cracking
- Cross-bracing and lateral support evaluation
- Decking support beam condition
- Fastener and hardware corrosion

Water Intake & Outfall Systems
Lake Tahoe water intake pipes supply drinking water, snowmaking, and resort operations. We inspect for blockages, damage, corrosion, and sediment accumulation using divers and ROV depending on depth and access.
- Intake pipe condition and corrosion
- Screen and grate blockage assessment
- Pipe joint integrity and leakage
- Sediment accumulation around intakes
- Support system and anchoring condition
- Flow capacity verification

Seawalls, Breakwaters & Riprap
Erosion control and wave protection structures require regular inspection to identify shifting, undermining, and failure before they threaten adjacent property or water quality.
- Seawall integrity and settlement
- Riprap displacement and voids
- Undermining and scouring detection
- Breakwater structural condition
- Erosion and sediment transport patterns
- TRPA compliance for shoreline structures

Dams, Reservoirs & Flood Control
Underwater dam and spillway inspection for safety compliance, structural integrity, and early detection of seepage, cracking, or erosion that could compromise flood control infrastructure.
- Dam face and spillway condition
- Concrete surface cracking and spalling
- Seepage and erosion detection
- Gate and valve mechanism inspection
- Embankment stability assessment
- Regulatory compliance documentation

Choosing the Right Inspection Method
Most infrastructure inspections benefit from both divers and ROV — we deploy whichever method delivers the most accurate, cost-effective results for your specific project.
🤿 Diver Inspections
Best for: Shallow to mid-depth structures (under 100 feet) requiring tactile inspection, manual probing for rot or corrosion, thickness measurements, and hands-on damage assessment.
- Wooden piling sounding and rot detection
- Steel thickness measurements with ultrasonic gauge
- Manual debris removal from intakes or grates
- Physical probing of concrete spalls and cracks
- Fastener and hardware security verification
🤖 ROV Inspections
Best for: Deep water structures, hazardous environments, large-area surveys, and projects requiring extensive video documentation for engineering analysis or regulatory compliance.
- Water intake pipes in 100–500 foot depths
- Dam face inspections in deep reservoirs
- Large marina infrastructure surveys
- Live 4K video for real-time engineering review
- Permanent HD video records for compliance files
What You Receive
Every infrastructure inspection includes comprehensive documentation suitable for engineering analysis, regulatory compliance, insurance requirements, and capital planning.
📋 Standard Inspection Deliverables
- Written Report — Detailed findings with prioritized recommendations
- HD Video Footage — Complete 4K video of all inspected areas
- Annotated Photos — Still images with measurements and damage callouts
- Site Diagrams — Sketch maps showing inspection areas and findings
- Condition Assessment — Good/Fair/Poor ratings by component
- Maintenance Recommendations — Immediate, near-term, and long-term
- Cost Estimates — Budget-level repair and replacement costs
- Compliance Documentation — TRPA or other regulatory formats if required
🔄 Multi-Year Baseline & Comparison
The first inspection establishes a baseline. Subsequent inspections compare current condition to the baseline and prior years, tracking deterioration rates and validating maintenance effectiveness. This data supports evidence-based capital planning and helps justify budget requests for repairs before failures occur.
Lake Tahoe Infrastructure Challenges
❄️ Freeze-Thaw Cycles
Tahoe’s elevation (6,225 feet) means winter ice formation around pilings and structures. Freeze-thaw cycles accelerate concrete spalling, wood splitting, and metal fatigue — making annual inspections essential for early detection.
🪨 Abrasive Lakebed
Lake Tahoe’s granite sand and rock bottom accelerate wear on any infrastructure in contact with sediment. Intake pipes, footings, and riprap shift over time, requiring periodic verification of position and condition.
🌊 Wave Action & Zephyr
The Washoe Zephyr generates significant wave energy that pounds piers, docks, and seawalls. Repeated loading fatigues connections, loosens fasteners, and shifts structures — damage that’s only visible underwater.
📋 TRPA Compliance & Shoreline Regulations
Lake Tahoe infrastructure projects often require TRPA permits, environmental assessments, and compliance documentation. Our inspection reports include all necessary detail for agency submittals — condition photos, measurements, environmental impacts, and recommended repairs formatted to meet TRPA standards.

Our Inspection Process
1. Project Consultation
We discuss your infrastructure, inspection goals, documentation requirements, and any specific concerns. We review available drawings, prior inspection reports, and regulatory requirements.
2. Proposal & Scope
We provide a detailed proposal outlining inspection methodology (diver, ROV, or both), timeline, deliverables, and pricing. For TRPA or regulatory projects, we include compliance requirements.
3. On-Site Inspection
Our team deploys with all necessary equipment — dive gear, ROV, measurement tools, and documentation systems. We conduct systematic inspections following accepted standards and your project-specific requirements.
4. Reporting & Recommendations
Within 7–14 days (or per contract schedule), you receive the complete inspection report with HD video, annotated photos, condition assessment, and prioritized maintenance recommendations.
