Integrated Applications

Utility Detection Survey

Used before excavation, trenching, coring, and layout work where live services or buried obstructions could affect safety and schedule.

Definition

What this method is

Utility detection locates buried services and shallow obstructions using non-invasive geophysical methods such as GPR and related EM tools.

Used before excavation, trenching, coring, and layout work where live services or buried obstructions could affect safety and schedule.

How It Works

From field measurement to interpreted model

  1. 1Survey lines or grids are planned around the construction footprint or corridor.
  2. 2GPR or EM data are collected to detect changes caused by buried services or obstructions.
  3. 3Interpreted results are marked up for design review and field verification where required.

When to Use

Best-fit conditions for this method

  • Pre-excavation planning and permit work
  • Building retrofit, coring, and slab opening
  • Road, utility corridor, and plant-area construction

What It Can Help Identify

Subsurface features and signals

  • Buried service conflicts
  • Shallow obstructions and disturbed zones
  • Areas needing field verification before digging

Deliverables

What you receive

  • Utility target map
  • Marked-up field plan
  • Interpretation summary for construction teams

Typical Outputs

What the data looks like

  • Marked-up utility zones
  • Search-area plan
  • Priority verification notes

Applications

Common applications in the Philippines

Infrastructure and utilities

Building retrofit and fit-out works

Road and plant corridor works

Method Limitations

What this method cannot do alone

  • Coverage and confidence depend on site conditions, records, and target depth.

Geophysical results are interpreted models based on measured physical property contrasts. Results should be correlated with boreholes, test pits, drilling, geological mapping, laboratory data, or other direct investigation methods where required.

FAQs

Frequently Asked Questions

Can utility detection confirm all buried services?

No. It is a screening and interpretation service, so confirmation should be checked against records and direct verification where required.

Is utility detection suitable before excavation?

Yes. It is commonly used before trenching, coring, and excavation to reduce the chance of striking buried services.

What should be provided before a utility survey starts?

Site drawings, known service records, surface access details, and the proposed excavation or coring area help the survey be planned more effectively.
