Three Techniques to Cut Excavation Cycle Times Without Sacrificing Safety
According to Equipment Journal, utility excavation crews are leaving productivity on the table through over-digging, inefficient spoil handling, and underused machine technology. In a bylined piece from Wade Turlington, Head of Utility Products and Competence Development at Volvo Construction Equipment, three core techniques emerge as the primary levers for improving trenching performance without trading away safety compliance.
For subcontractors running utility crews in tight urban corridors, pipeline right-of-ways, or municipal infrastructure projects, this isn’t abstract advice. Slow cycle times and excessive backfill work are margin killers, and regulators don’t give you a pass for either.
Context
Turlington’s piece, published April 20, 2026, frames the central challenge of utility excavation as a constant three-way tension: daily production deadlines, shifting site conditions, and strict safety regulations. In Turlington’s words, as published in Equipment Journal, there is “no room for inefficient or risky choices” in this environment.
The article focuses on three operational areas where crews commonly lose time and money: bucket and shielding selection, spoil pile management and truck loading, and excavator work mode and grade technology. Each of these areas intersects directly with both safety compliance and production efficiency.
Analysis
The core insight here is that speed and safety in utility excavation are not opposing forces. They’re actually aligned when the right equipment and technique decisions are made upfront.
Take bucket selection. According to Equipment Journal, using a general-purpose bucket for precise subsurface work slows operations and wastes fuel. A purpose-built trenching bucket, narrower and longer, produces cleaner cuts with less over-digging. Less over-digging means less material to backfill, which directly compresses the back end of the job. The recommendation to use smooth-lipped buckets in softer soils for precision work also reduces the risk of damaging existing utilities, a cost that no subcontractor wants to absorb.
The quick coupler point is worth pausing on. Turlington states that swapping attachments with a quick coupler can save as much as an hour per shift. Over a multi-week utility project with multiple machines, that compounds quickly into real schedule and labor savings, without touching crew headcount or hours.
Shoring and trench shielding are framed not just as a safety requirement but as a productivity enabler. Under OSHA 29 CFR 1926 Subpart P, excavations five feet or deeper generally require protective systems, and a site shutdown for an unsupported trench carries immediate and severe costs. Turlington notes that trench box sizing matters: a box that is too wide forces crews to excavate extra material, burning time and fuel on work that doesn’t need to happen. When workers have confidence that trench walls are properly supported, they work more efficiently.
The spoil management guidance reflects a common field problem that rarely gets attention in equipment discussions. Regulations require spoil piles to be placed a safe distance from trench edges, but in congested sites, this can create significant swing arc inefficiency. The double-cut technique described by Turlington, creating a smaller nearby pile first, then using the machine’s reach to build a secondary main pile further out, is a practical workaround that reduces surcharge load risk while maintaining site access for other crews and vehicles. It’s the kind of field-level problem-solving that experienced operators know but newer crews often skip.
On the technology side, the article highlights load-sensing hydraulics and work mode management as tools that most operators have available but underuse. According to Equipment Journal, most modern excavators are equipped with load-sensing hydraulics that automatically balance flow and pressure to prevent engine lugging. The practical guidance is straightforward: use maximum hydraulic flow for high-production excavation phases, then shift to pressure-priority mode for precise grading and pipe-setting work. This isn’t new technology, but it’s consistently underutilized in the field.
What It Means for Subcontractors
- Bucket selection is a margin decision, not just a technical one. Running a general-purpose bucket on precision utility work costs you in over-digging and fuel. Match the bucket to the soil and task.
- A quick coupler is a productivity investment. If Turlington’s figure of up to an hour saved per shift holds on your projects, the math on coupler cost pays off fast on any multi-week utility job.
- Trench box sizing affects excavation volume. An oversized box means more material to move. Right-sizing shoring to the machine’s lifting capacity and project specs cuts unnecessary work out of the cycle.
- The double-cut spoil technique solves a real regulatory and operational problem. It keeps spoil at compliant distances while reducing swing arc and maintaining site access. It’s worth building into crew standard practice.
- Know your machine’s work modes. Operators who actively manage hydraulic modes for different phases of the trench cycle get better cycle times and burn less fuel. This is a training and supervision issue as much as an equipment issue.
- Safety compliance and production efficiency point in the same direction. A shutdown site or a utility strike costs far more than the time saved by cutting corners. The techniques here reduce both safety risk and cycle time simultaneously.
