His job at ÅF – climbing vertical concrete walls
Oskar Lynxén has climbed above cascading water, walked the tunnels of the Stockholm Metro with a 3D scanner and travelled the world to keep up to date with the latest technology. Oskar Lynxén is a measurement technician at ÅF.
Forget spirit levels and yardsticks. Modern measurement techniques are far more advanced than that. Oskar Lynxén works with measurement techniques at ÅF, meaning that he installs measuring instruments and keeps an eye on everything from water pressure and temperature to inclination and movement in buildings and plant.
“The job is exciting, challenging and diverse. One day I’m in a mucky hole with my measuring equipment, the next I’m selling project planning and management services to a major client,” he says.
Climbing vertical concrete walls
As equipment often needs to be installed in hard-to-reach places, ÅF arranged for Oskar Lynxén to train as an industrial climber. He has ascended 30-metre high concrete hydroelectric dams and climbed bridges to inspect for damage. With no handholds to cling to on smooth walls, he has to drill a hole and hammer in an expanding anchor to give himself something to hold on to.
“It takes a long time but it’s a real buzz to reach the top of tall buildings and other constructions,” says Oskar Lynxén.
One happy memory is of working on the Seitevare Power Station 80 on the Lule River, which is normally only accessible by mountain hiking, and living in a tourist cabin surrounded by reindeer and magnificent natural scenery. He also gets to see places to which there is no public access, such as the inside of nuclear power plants and underground rail tunnels. A couple of years ago he was part of a project to 3D scan the entire Stockholm Metro system using a specially built wagon that was pushed manually around the tracks by night. Previously, no 3D model of the Metro system existed but now it’s possible to see exactly how it looks down there – from the position of points and signals to the height of the track and the general amount of clearance.
“It’s very useful, for example when introducing new rolling stock or installing new equipment,” says Oskar Lynxén.
A great deal of travelling
Oskar spends around a third of his time at ÅF’s office in Solna but otherwise, he’s out in the field. His work involves a great deal of customer contact and either installing and setting up new measuring equipment or maintaining existing equipment. ÅF also collaborates with manufacturers worldwide – something which has taken Oskar to countries such as Italy, Iceland and the United States. Because measuring equipment is so technically advanced, programming and system administration are also a part of the job.
“For example, we build and maintain project pages on websites that show measurement data,” explains Oskar Lynxén.
His goal for the future is to continue developing in his specialist role.
“I enjoy working at ÅF and feel that I can develop in the fields that interest me,” he says.
