ESCOT™

EDVIRT® SPRAYED CONCRETE OPERATOR TRAINING CERTIFICATION

The ESCOT™ certification is a standard created by Edvirt AB back in 2012. It is a proof that individuals have gone through and passed a structured sprayed concrete operator training program. The program includes both theory and practical modules and individuals performance are objectively evaluated.

CONTENT
The program's theory module includes the following subjects:

  • The purpose of sprayed concrete

  • The purpose of training sprayed concrete operators

  • Rock and ground support

  • Concrete technology

  • Spraying equipment

  • Application and spraying technique

  • Health, safety and environment

The theory can be done online through Edvirt Online Academy™ or in a classroom format. The theory is specified to take approximately 8 hours to finish including a test with 30 questions. Individuals need at least 75 % correct answers to pass the test and theory module. 

The practical module includes training and tests with a sprayed concrete simulator (VR Shotcrete Simulator™), that has been scientifically validated by an independent body (University of Technology in Luleå). Individuals need to show that they are qualified by passing 14 assignments containing the following activities:

  • Startup and shutdown procedure

  • Safe spraying (operator position, avoiding fall-outs etc.)

  • Use of remote control and robot maneuvering

  • Spraying angle and distance

  • Concrete adhesion and rebound

  • Pump and accelerator dosage

  • Preparation and washing rock surface

  • Spraying small and large areas

  • Thickness control and waste minimization

  • Systematic spraying

  • Time-limited spraying

  • Filling an over-break

  • Corner spraying

The practical module is specified to take 16-40 hours dependent on the skill level of the individual. The attendee needs to finish all assignments or spend at least 10 effective hours trying all of them out.

The practical module starts off with a spraying test. The same test is later conducted after the training to in order to evaluate performance improvement for each attendee.

CERTIFICATE
Each individual passing the program will be awarded a printed or digital ESCOT™ certificate.

TIME
The certificate is valid for 5 years.
