R&R Sy-Tec has provided field inventory services for utilities since 1969. 

As technology has advanced, so have we. The work once done entirely on paper is now performed with combined data-collection/GPS devices that are accurate to within 30 centimeters.

We have found that we can provide the best field inventories by working closely with utility personnel during the project. And, even more important, during the planning stage. This helps us to determine the right approach for each project.

Not all utilities are at the same starting point for a field inventory. Some are still using paper maps and pole cards. Others have electronic base maps and little else. And some have fairly complete inventory information in a database - but do not have accurate electronic maps.

For this reason, we offer field inventory services under three basic scenarios; which vary in cost and complexity…


Full Inventory

 

Utilities with little or no electronic plant data often choose this route.
 

An inventory of this sort can be used to generate complete plant maps and databases from the ground up. The entire plant model is generated from data gathered in the field.
 
 
Location and Connectivity Inventory

This scenario works well for utilities that have a well maintained plant database, but do not have accurate electronic maps.

In this type of field inventory, usually done in urban areas, we provide GPS coordinates for all required poles, stations, and services. Because our field crews work by circuit, the data from this type of field inventory can also be used to establish a connectivity model in the plant database.



Interpolated Location Inventory

 
This is a very economical approach for rural utility plants that have good data, but lack accurate maps – and have a limited budget.

Rural plants will often have areas consisting of pole, after pole, after pole – all with the same framing; all with the same back span. In such an area, it may not be necessary to record a GPS location for each pole.

In the example below, it is known ahead of time that poles 1003 and 1004 have exactly the same construction units as pole 1002 - which has been visited by one of our field technicians. We need only get GPS locations for poles 1002 and 1005, and to specify the ruling span. Our post processing software will determine the proper location for poles 1003 and 1004, place them on the plant map, and create the associated database records.

 


 
Benefits

It all comes down to this:  If plant data is in a comprehensive database, and linked to an accurate plant map, things happen faster.

 
  • If staking engineers need to change equipment at a large number of locations, there is no need to locate, update, and replace the pole cards for each station.
  • Line crews can go to a job site with correct materials and equipment, and can locate work more easily.
  • Planned outages can be traced instantly.
  • After work is completed in the field, the plant map and database can be brought up to date automatically.
  • Account personnel can have the CPR ledger updated with no need to research each job.
  • Engineering personnel can analyze plant conditions in far less time.

When things happen faster, they cost less.

We recently asked a client utility to track the hours spent on certain tasks during the year after a field inventory. They compared these times to the time spent on similar tasks prior to the field inventory.

What they learned was amazing…

They analyzed the cost of the reduced hours for various operations and procedures; and compared then to the overall cost of the field inventory – $100,000 in this case.

Their savings – listed as a percentage of the field inventory cost – are listed below:

 
  • Saving for crews and staking dept. by using up to date maps and data
25.5% 
  • Work order and maintenance efficiency by utility
25.5%
  • Work order closing and  CPR's entries by office personnel
25.5%
  • Job layout and estimates
7%
  • Correct framing, quantities, planning
14%

In other words…

 
        97.5% COST RECOVERY IN ONE YEAR
 

Whatever field inventory method is right for your utility, R&R Sy-TEC is the right company.
