LiDAR vs Surveying In the Field: Choosing the best option

The Problem Every Project Manager Must Solve

When managing infrastructure projects, this question likely arises often: “Should we use traditional surveying techniques, or do we invest in LiDAR technology?” Considering the amount of major project consultations I’ve worked on, I can tell you there are both magnificent successes and spectacular errors. Most of the time, however, the answer is not what people expect.

The truth of the matter is, the real discussion is not centered around what technology is better, but rather determining the conditions which each approach’s application will maximize success in relation to costs, timelines, and deadlines.

What This Means for Your Bottom Line

Let me cut straight to what matters most: project outcomes and ROI. Here’s what our analysis of recent projects reveals:

Business Impact Metric Traditional Methods LiDAR Technology Improvement
Data Collection Rate 50-100 points/hour 100,000-2M points/second 10,000x+ faster
Field Time (12-mile highway) 18 days 6 hours 97% reduction
Labor Efficiency Baseline 70-80% time reduction Significant savings
Design Change Orders Baseline 67% reduction Major cost savings
Clash Detection Issues Baseline 78% reduction Risk mitigation
Project Breakeven Point N/A 15-20 acres Clear ROI threshold
Processing Cost Minimal 60-70% of project cost Higher overhead
Accuracy (Vertical) ±3-5mm ±1-15cm Trade-off consideration

Real-World Project Examples:

  • Highway corridor survey: 12-mile project using LiDAR completed in 6 hours versus 18 days with traditional methods.
  • Disaster response: 27 damaged bridges surveyed in 3 days versus weeks using conventional methods.
  • Hospital renovation: Reduction in clash detection using terrestrial LiDAR for MEP documentation.
  • Volume calculations: LiDAR methods found to be 9.4% more accurate than traditional cross-section approaches

The Strategic Framework: When to Choose What

Based on our project experience, here’s the decision framework I recommend to clients:

Choose Traditional Surveying When:

  • Non-negotiable precision needs to be upheld (±3-5mm accuracy required)
  • There is small scale project (15 acres or less)
  • Solely cost sensitive is the primary concern
  • There is legal boundary work that needs to be done
  • Construction staking requires placement of features at precise location

Best applications: Property boundaries, construction layout, precise engineering measurements, control networks

Choose LiDAR When:

  • Comprehensive data provides additional project value
  • Large areas need surveying (20+ acres)
  • Inaccessible terrain poses safety or access challenges
  • Time constraints are critical
  • 3D modeling and visualization are project requirements
  • Volume calculations need high accuracy

Best applications: Topographic mapping, as-built documentation, environmental monitoring, disaster response

The Hybrid Approach (Our Recommended Strategy):

For more sophisticated work and projects, the most incorporate both toward technology approaches to obtaining the desired result:

  • Use conventional work for control networks and guaranteed high precision points
  • Use flexible circled equipment which were LiDAR equipment sensors coverage demonstrative tools
  • Check measurement routinely conventional and scope-fixed verify that means critical measurements of conventional means
  • Result: With regards to achieving core milestones, 78% of major engineering did letiese iste interm noossan stvillebui this way integrated approach use.

Risk Management: Avoiding Common Pitfalls

In my experience as a consultant, these are the common pitfalls that will inevitably waste a project’s time and money:

Traditional Surveying Risks:

  • Overly optimistic estimates for field time needed
  • Safety concerns in difficult terrain
  • Data deficiencies leading to follow-up appointments
  • Minimal background knowledge relevant to design teams

LiDAR Implementation Risks:

  • Overvaluation of what accuracy could be achieved
  • Underestimation of how complex processing would be and its associated costs
  • Insufficient training of staff on the new processes
  • Lack of acceptance from regulators in certain regions

Our Strategic Recommendations

For Smaller to Medium Sized Projects (Under 20 Acres)

Do not deviate from standard practices unless there are particular LiDAR benefits (areas that cannot be accessed, 3D imaging) that merit costs.

For Larger Projects (Over 50 Acres):

LiDAR usually offers the best value in terms of time and the amount of data gathered. Supplement with the use of traditional control points.

For Complicated Infrastructure:

Employ a hybrid approach that combines traditional accuracy with LiDAR coverage. This has yielded the best results out of all other strategies from our project portfolio.

For Business As Usual:

If you consistently manage projects larger than 25 acres or require quick responsiveness, consider developing internal LiDAR capabilities.

The Future Landscape: Preparing for What’s Next

The technology evolution isn’t slowing down. Here’s what we’re tracking for our clients:

  • Market expansion: This is expected to increase by a rate of 22.7% CAGR until 2028.
  • Cost minimization: LiDAR hardware costs reduced by 32% over the past 5 years.
  • Advancements in processes: Through automated classification, there will be an 85% reduction in manual labor required.
  • Integration direction: There is expected to be near universal adoption of hybrid approaches in 5 years.

Optimizing Business: The Action Plan

Step 1: Analyze your project portfolio

  • Determine the yearly acreage covered in the survey.
  • List the repeating use cases.
  • Assess the prevailing cost model.

Step 2: Run pilot testing

  • Collaborate with service providers to complete initial projects.
  • Evaluate results using benchmarking against traditional approaches.
  • Calculate ROI on pilot projects.

Step 3: Construct capabilities

  • Custom train current LiDAR staff in survey operations (heritage surveyors do not require much adjustment).
  • Develop proven ROI equipment. The return on investment needs to be assured first.
  • Build processing work flows.

Step 4: fine-tune your operations

  • Implement hybrids.
  • Create uniform standard control rules.
  • Refine and check continuously.

The Bottom Line

Having implemented many projects, the most effective organizations do not settle for mastering one option – traditional surveying versus LiDAR. They strategically make use of both where applicable.

The issue at hand is no longer whether LiDAR will replace traditional surveying (it won’t). It is how fast you can master the use of both technologies to suit your project’s needs.

Strategically informed organizations tend to perform much better than those adopting technology without a carefully reasoned approach or failing to adopt technology due to an inflexible mindset. The former consistently outpace competitors as a result.

Ready to Optimize Your Surveying Strategy?

Unlocking the potential of every project starts with understanding that uniqueness lies at the core of each endeavor. If you are assessing surveying technologies for potential or existing projects, there is an opportunity to optimize your current approach based on insights I would like to share.

Imagine for a moment focus shifts to strategic deployment of technology: unlike the scenario where benefits remain ambiguous in terms of project outcomes, costs, and even competitive edge. Embrace the alternative: the question shifts to whether the focus is on controlling outcomes or enables setting the terms as a leader in technology driven transformation.
