Comprehensive Site Preparation & Mass Excavation in Miami
Successful commercial construction starts from the ground up. At EZ Plumbing, we don’t just dig holes; we engineer the site’s foundation. Our mass excavation services involve moving large volumes of earth to create the perfect “footprint” for your structural needs. By using advanced cut and fill techniques, we balance the site’s elevation, ensuring that every cubic yard of soil is stabilized for long-term durability.
1. Professional Land Clearing & Precision Grading
Before the first brick is laid, the land must be pristine. We handle complete site preparation, which includes:
Debris & Vegetation Removal: Clearing the lot of old structures, roots, and rocks.
Subgrade Preparation: Compacting the lower layers of soil to support heavy commercial loads.
Erosion Control: Implementing silt fences and drainage slopes to prevent soil runoff during Miami’s heavy rain seasons.
2. Specialized Utility Trenching for Commercial Systems
Infrastructure is the lifeline of any building. Our team specializes in precision utility trenching for:
Commercial Sewer Lines: Deep-trench digging with proper shoring to ensure safety and slope accuracy.
Water Mains & Electrical Conduits: Clean, straight channels that meet all Miami-Dade utility codes.
Fire Line Excavation: Meeting specific depth requirements for high-pressure fire suppression systems.
3. Foundation & Footing Excavation
For high-rise buildings or retail centers, the foundation is everything. We provide:
Deep Structural Footings: Precision digging that follows your engineer’s blueprints to the inch.
Underground Parking Excavation: Mass earthmoving for subterranean levels, managed with professional shoring to protect adjacent properties.
Precision Excavation for Commercial Plumbing & Sewers
Commercial properties in Miami face unique drainage challenges, from shifting sandy soils to heavy tropical rain demands. At EZ Plumbing, we combine heavy-duty excavation with advanced plumbing diagnostics to ensure that your underground infrastructure is handled with surgical precision. We don’t just dig; we diagnose, excavate, and restore.
1. Sewer Camera Inspections: Know Before You Dig
Traditional excavation often relies on guesswork, leading to unnecessary property damage. We use High-Definition Sewer Cameras to navigate your lines before a single shovel hits the ground.
Pinpoint Accuracy: We identify the exact location of tree root intrusions, collapsed pipes, or severe scaling.
Minimized Disruption: By knowing the precise “target area,” we reduce the size of the trench, saving you time and money on surface restoration.
2. Main Line Repairs & Storm Drain Excavation
When a commercial main line fails, your entire operation stops. We provide professional excavation for:
Deep Sewer Mains: Managing complex depths with OSHA-compliant shoring to replace or repair municipal connections.
Storm Drain Systems: Excavating for catch basins and large-diameter pipes to prevent parking lot flooding during Miami’s peak storm seasons.
Grease Trap Lines: Specialized digging for restaurant and industrial kitchen drainage systems.
3. Hydro-Excavation: The Safe, Non-Destructive Choice
In congested Miami areas where fiber optics and high-voltage lines are buried, traditional backhoes can be risky. We offer Hydro-Excavation (Vacuum Excavation):
Pressurized Water Precision: We use high-pressure water to break up soil while a powerful vacuum removes it.
Safe Daylighting: This “Non-Destructive” method exposes sensitive utilities without the risk of a strike, keeping your site compliant and safe.

How Much Does Commercial Excavation Cost in Miami? 2026 Estimates
Commercial excavation is a major investment, and in 2026, pricing in Miami is heavily influenced by soil composition (limestone vs. sand) and site accessibility. At EZ Plumbing, we believe in 100% price transparency. Understanding these benchmarks helps you budget effectively for your next commercial development or utility repair.
1. Per Cubic Yard Pricing: Why Soil Density Matters
In Miami-Dade County, excavation is typically priced by the volume of earth removed.
Light/Sandy Soil: $3.00 – $7.50 per cubic yard.
Average/Mixed Soil: $7.50 – $13.00 per cubic yard.
Heavy/Wet Soil or Loose Rock: $13.00 – $18.50 per cubic yard.
Hard Rock (Requires Jackhammering): $65 – $240+ per cubic yard.
Expert Note: “Mass excavation” for large building footprints usually brings the per-unit cost down due to the scale of the project.
2. Hourly Rates vs. Project Quotes
While most developers prefer a fixed-bid quote for the entire project, smaller utility repairs or exploratory digging are often charged hourly:
Operator + Heavy Excavator: $275 – $450 per hour.
Operator + Standard Backhoe: $160 – $260 per hour.
Mini-Excavator (Tight Spaces): $110 – $155 per hour.
Mobilization Fee: Most Miami contractors charge a one-time fee ($500 – $900) to transport heavy machinery to your site.
3. The "Rule of 5" in Excavation Safety
Safety isn’t just a priority; it’s a cost factor. We strictly follow the Rule of 5:
Depth Protection: Any trench 5 feet deep or more must have a protective system (Shoring, Shielding, or Sloping) to prevent cave-ins.
Atmospheric Testing: If a trench is 4 feet deep or more, we test for oxygen levels and hazardous gases before entry.
Egress (Exit): A ladder or ramp must be within 25 feet of any worker in a trench.
Impact on Pricing: Professional shoring adds to the initial quote but prevents catastrophic site delays and OSHA fines.
| Project Type | Typical Price Range | Key Factors |
|---|---|---|
| Basic Land Clearing | $1,400 – $5,800 | Trees, brush, and debris removal. |
| Site Grading & Leveling | $400 – $6,500 | Ensuring proper drainage slopes. |
| Utility Trenching (200 ft) | $1,000 – $2,400 | Digging for water/sewer/electric. |
| Full Site Prep (per Acre) | $25,000 – $43,500 | Clearing + Grading + Subgrade compaction. |
Why Licensed Expertise Matters for Miami Excavation
Excavation is one of the most high-risk phases of any commercial project. In Miami-Dade County, the combination of a high water table and porous limestone creates unique challenges that only a specialized team can navigate. At EZ Plumbing, we prioritize safety and legal compliance to protect your investment and our crew.
1. Navigating Miami-Dade County Codes & Sunshine 811
Before a single bucket of dirt is moved, strict legal protocols must be met.
Sunshine 811 Compliance: Florida law requires that Sunshine 811 be notified at least two full business days before digging. This ensures all underground utility lines (water, gas, electric) are marked with APWA color codes to prevent catastrophic strikes.
Permit Accuracy: From unincorporated Miami-Dade to specific city limits, we manage the necessary “Public Works” and “Building” permits required for mass grading and trenching. Failure to comply can lead to heavy OSHA fines and project shutdowns.
2. Understanding the 3 Types of Excavation in Florida
Not all dirt is the same. We categorize excavation based on the material, which dictates the machinery and time required:
Topsoil Excavation: Removing the uppermost organic layer (usually 6-12 inches) to prepare for landscaping or foundations.
Earth Excavation: Digging into the layers below the topsoil. In Miami, this often involves dealing with sandy soil that requires specific sloping to stay stable.
Rock Excavation: The most challenging type. Florida’s limestone often requires hydraulic breakers or specialized heavy-duty excavators to clear the path for deep footings or sewer mains.
3. Risk Mitigation: The Role of Professional Shoring
A trench collapse can happen in seconds. To prevent accidents and ensure structural integrity, we implement advanced risk mitigation:
Professional Shoring: For any trench 5 feet deep or more, OSHA mandates a protective system. We use aluminum hydraulic shoring or trench boxes to support the walls against soil pressure.
The “2-Foot Rule”: We keep all excavated “spoil” and heavy machinery at least 2 feet away from the trench edge to reduce the risk of a cave-in.
Atmospheric Testing: In deep excavations (over 4 feet), we test for oxygen deficiency or hazardous gases before any worker enters the zone.

Frequently Asked Questions About Commercial Excavation Services
For a 5-acre commercial site in Miami, mass excavation and clearing costs typically range from $125,000 to $215,000. This includes:
Vegetation Removal: $1,500 – $3,000 per acre.
Mass Grading: $5,000 – $15,000 per acre depending on the slope.
Subgrade Compaction: Essential for large building footprints.
Variable Factors: Costs will increase if heavy limestone (rock excavation) is encountered or if the land requires significant “fill” to meet flood zone elevation codes.
On average, digging a 200-foot trench for sewer, water, or electrical lines costs between $1,200 and $4,500.
Standard 2-3ft Depth: $6 – $12 per linear foot.
Deep 5ft+ Trench (with Shoring): $15 – $25+ per linear foot.
Complexity: If the trench crosses existing concrete parking lots or requires navigating around other utilities, specialized “Hydro-Excavation” may be needed, which increases the hourly rate but ensures safety.
Yes. Hiring a specialist like EZ Plumbing is critical for protecting structural integrity. A general laborer might miss subtle signs of soil instability or ignore the “Rule of 5” safety protocols. Professional excavators provide:
Laser-Guided Precision: Ensuring foundations and sewer slopes are accurate to the millimeter.
Liability Coverage: Licensed contractors carry high-limit insurance that protects you from OSHA fines and utility strike damages.
Equipment Efficiency: Using the right-sized excavator saves days of labor costs.
Excavation is calculated by Cubic Volume (Length x Width x Depth), not just square footage.
The Formula: (1,000 sq ft) x (Depth in feet) / 27 = Cubic Yards.
Example: If you need to dig 3 feet deep for a 1,000 sq ft foundation:
1,000 x 3 = 3,000 cubic feet.
3,000 / 27 = 111.1 Cubic Yards.
Total Price: At a Miami average of $10 per cubic yard, your estimated cost would be $1,111 (excluding mobilization and debris hauling).
