Dirt Ops begins by analyzing the site’s engineered utility plans to understand the placement and depth of proposed lines, ensuring that routes are efficient and comply with design specifications.

We coordinate directly with service providers such as Duke Energy, Piedmont Natural Gas, and local municipal departments to verify connection points and service routes. This step ensures all utilities align correctly with the existing grid.

Before any digging, Dirt Ops contacts 811 to locate and mark existing underground utilities. This state-required step prevents costly damage and keeps the site safe for all crews.

Once utilities are marked, our team verifies and records their exact positions, making necessary adjustments to our plans to avoid conflicts or clearance issues.

After all verifications, we finalize the utility layout, ensuring proper spacing, grade alignment, and compliance with state and municipal standards. This detailed coordination ensures the installation proceeds safely, efficiently, and without disruption.

Before excavation begins, we verify trench routes on-site against utility plans, ensuring all markings align with locates and that trench spacing meets state-mandated clearances between utilities.

Our operators excavate trenches to the required depth and width for each utility. Sewer and water lines demand deeper trenches with a consistent slope, while electrical and communication lines are typically shallower but must be uniform and secure.

Once the trench is open, our foremen inspect soil conditions, checking for stability, moisture content, and potential groundwater intrusion. If necessary, we reinforce trench walls or dewater to maintain safe working conditions.

A uniform layer of bedding material—usually sand or crushed stone—is placed and compacted at the bottom of the trench. This creates a firm, smooth surface that supports the utility lines evenly and protects them from point loads or sharp debris.

After utilities are laid, we verify line alignment, slope, and depth before backfilling. We then fine grade the area around the trenches to match site elevations and ensure proper drainage for long-term performance.

Before installation begins, all pipes, fittings, and conduit materials are delivered, inspected, and staged near their respective trench locations. This organization streamlines workflow and minimizes handling during placement.

We begin with deeper utilities—typically sewer and water lines. Using laser levels and slope indicators, we ensure gravity-fed systems maintain proper fall and alignment. Water lines are pressure-tested before connections are made.

Next, we install storm drain systems using reinforced concrete pipe (RCP), HDPE, or corrugated metal pipe (CMP). Each line is positioned to handle runoff efficiently, directing flow to retention areas or outfall structures.

Shallower trenches are then used for electrical and communication conduits. Conduits are separated and spaced per code to prevent interference and allow for safe maintenance access.

Once all utilities are installed, we conduct inspections with municipal or engineering representatives. Water lines undergo pressure tests, sewer lines are air-tested, and storm drains are visually inspected for grade and joint integrity.

After approval, trenches are carefully backfilled in layers, compacted, and restored to final grade. Each line is rechecked for elevation consistency to ensure that the entire utility system operates as designed.

Dirt Ops begins by selecting the appropriate backfill material—typically native soil, select fill, or crushed stone—based on soil conditions and project requirements. The material is conditioned for proper moisture content to achieve ideal compaction results.

Backfill is placed in lifts, usually 6 to 12 inches thick, to ensure even compaction throughout the trench. This step prevents voids and uneven settlement that could jeopardize the stability of the installed utilities or surface improvements above.

Each layer is compacted using vibratory or sheepsfoot rollers, plate compactors, or jumping jacks, depending on the trench width and soil type. Field density tests confirm that compaction meets NCDOT or local engineering standards before additional lifts are placed.

After achieving proper compaction, the trench is topped off and fine-graded to match surrounding elevations. The finished surface is left smooth and stable, providing a solid foundation for paving, concrete placement, or landscaping. Dirt Ops ensures every trench is restored to a condition that’s as strong—or stronger—than the original ground.
