Frequently Asked Questions Top
- How much will it cost?
We will need to know several details about the site and conditions to provide an estimate. All work is charged on an hourly basis.
- When are you available to locate?
Pathfinder is available Monday - Friday, Weekends and Public Holidays. Call out | Emergency work is available after 5.00pm and before 7.00am
- Do you locate telecom?
Yes we can locate telecom both copper and fibre optic services.
- Does somebody need to be present when your locating?
No provided prior arrangement with property owner or site contractor has been made and access to property is available.
- How long will it take?
There are many things to consider that may vary the time.
The locator maybe able to give an approximate time given prestart conversation, images or inspection.
- Number of services to locate.
- Availability to service access points.
- Terrain to traverse while locating services.
- Interference from nearby services or infrastructure.
- Do we need to supply plans?
If you have any plans available even hand sketches these will be very helpful to the locator. Most utility providers can supply plans up to the property boundary but not usually within the property.
- Do you supply maps or GPS data of located utilities?
Not unless specifically asked for. These services are available via third party qualified practitioners and will incur additional charges. Pathfinder only paints the ground to indicate their location.
- What's the next step to getting Pathfinder out for underground utility locating?
Email firstname.lastname@example.org with your contact details, preferrably an email address for billing, a site address or location, where possible a Google Maps screenshot.
- Why use Pathfinder when I can get all services marked up by the utility owners?
- Pathfinder can start within 48 hours if requested.
- All utilities can be marked up within a 48 hour period.
- Pathfinder will locate utilities on private property.
- On large projects Pathfinder can assist or manage utility locators.
- Pathfinder will locate local council services.
- How deep does the Ground Penetrating Radar scan?
The Ground Penetrating Radar used for locating is designed for utility scanning. It has successfully located services at 2.5m. However site subterrain conditions do affect the Ground Penetrating Radars ability.
- Does the Ground Penetrating Radar detect waterpipe?
The Ground Penetrating Radar does not detect any specific objects or items. The GPR data is processed and displayed as a radar-gram depicting the change in signal velocity. The locator must interpret the Ground Penetrating Radar images.
- Do you have a system for checking and verifying radiodetection service locates?
Pathfinder has a Damage Prevention And Awareness Policy. Referencing documents outline industry practices for checking EMF distortion and triangulation applications to determine actual conductor location.
- What regions of the country do you cover for service?
Predominantly the Lower and Central North Island. We will travel further provided travel and accommodation are considered.
- What is the quickest and most cost effective way to locate a proposed site excavation?
Have the proposed trench alignment or excavation site marked out by the customer. This will significantly reduce time. All Utility searches and scanning will be reduced to the marked area. The alternative option where Pathfinder find all the services in a given area then the customers decides the alignment based on the findings is a far longer process.
- How far can you trace a cable?
If the cable is in good condition with no interferring energised sources nearby and a good access point. Then it's possible to trace up to 1.5km
- Can you find cable faults?
Yes we can find cable faults. The cable must be disconnected at each end including the earth. Our equipment can find cable breaks and shealth faults.
- What does EOI mean?
When locating underground utilities, the locator may occasionally designate a utility to an unknown termination point. The locator will label this as EOI (End of Information) with paint on the ground. This term EOI accurately describes the situation. EOI's are not all that uncommon. Broken tracer cable on gas systems, and sections of plastic pipe in a primarily ductile pipe system will all produce EOIs. Additionally, drastic changes in elevation or utility depth can also produce EOI points.
- Are you Certified BeforeUDig locators?
Pathfinder locators are not certified by BeforeUDig. We are happy to provide work referees and information regarding;
- Standard Operating Procedures.
- Damage Prevention & Awareness Policy.
- Personnel locator training.
- What should we do if we strike/find or damage a utility marked or not marked by Pathfinder?
Notify the utility provider. Take photographs and if required follow up with your incident reporting. Even if Pathfinder locators are onsite they cannot repair any damaged utilities. Please read the Terms And Conditions Of Underground Utility Locating.
- Your paint markouts didn't have a window like other utility paint markouts?
Pathfinder will paint a 500mm extent window on a difficult locate or where the locate has been triangulated. Otherwise a spot or cross to indicate the utilities position and directional lines either side to indicate direction.
- Where are the depth readings taken from?
Using Radiodetection equipment with the exception of Sondes the depth reading will be to the center of the utility. Using Ground Penetrating Radar the depth reading will be to the top of the utility. Using a sonde in a duct or pipe and the depth reading will be to the bottom of the duct or pipe.
- What do the marker paint colours represent?
These colours are standard across the industry.
- Orange - Power
- Purple - Communications
- Yellow - Gas
- Green - Stormwater
- Red - Sanitary Sewer
- Blue - Potable Water
- White - Unidentified
- Does the CAT model locator detect Omni Marker balls?
No, a locator with the specific marker ball or EMS marker application can only be used.
- Do the Omni Marker balls require batteries?
No, the marker balls are activated by the hand held locator. Normally the hand held locator can trigger and detect a marker ball upto 2m in any direction.
