A slackline show to mark the opening of an industrial site: that’s what Slackline Events put on Tuesday, September 1, 2026, for Condecta in Wikon, in the canton of Lucerne. On that day, the company inaugurated its center of excellence for modular construction and celebrated, along with its staff, the arrival of WL Bau. Slackline Events, a Swiss highline and slackline performance company based in Veytaux, near Montreux, designed an indoor acrobatic slackline show centered around the ribbon-cutting ceremony, performed in the midst of the employees, to bring the celebration to a close.

Objectives: To turn an internal launch event into a shared experience
Condecta wanted to bring together its employees from all over Switzerland in Wikon, show them the site, explain its strategy, and celebrate the integration of WL Bau. There were also stations showcasing the company’s latest developments, as described in its LinkedIn post.
The CEO wanted a show tied to the exhibition hall and the company’s products, rather than a standalone performance: five simple, concrete messages for a diverse audience—from frontline teams to senior management—culminating in the slogan “Wir für die Schweiz.” The show was also designed to flow seamlessly from the CEO’s speech to the ribbon-cutting ceremony and the caterer’s remarks, with no downtime.

Background and Challenges: An Active Market Hall That Is Too Low for a Highline
The Wikon site has become Condecta’s center of expertise for modular construction. In operation since 1959 (see its history), the company has consolidated this business area there across more than 12,000 m², including 7,000 m² of production facilities. According to its press release, it acquired WL Bau AG on August 31, 2026: its 25 employees are joining Condecta, which now employs approximately 200 people across 15 sites.
Condecta CEO Olivier Annaheim summed up the significance of the day: “Hier in Wikon entsteht nicht einfach ein neuer Standort. Hier entsteht ein Stück der Schweiz von morgen.” In English: It’s not just a new facility being built in Wikon, but a piece of the Switzerland of tomorrow.
The show took place in the large hall, where complete space systems are assembled and tested before delivery. Four constraints guided the project:
- A hall that was too low for a highline. A highline performance requires a height of at least 8 meters: we proposed an acrobatic show on a line stretched at head height.
- It's impossible to make it completely dark. Skylights let in daylight, so the idea of a light show was scrapped.
- A busy warehouse. Containers, modules, and visitor stations filled the space; the survey determined the route's alignment.
- A bilingual audience in the middle of a meal. During a buffet, attention spans are limited: we recommend about 10 minutes. The staff is primarily German-speaking, with about 30 colleagues from French-speaking Switzerland expected to attend.

Our solution: an acrobatic slackline show in the heart of the hall
Slackline Events managed the project from start to finish: location scouting, technical specifications, art direction, voice-over, sound design, and installation. Our technical manager prepared the technical specifications to approve the structural supports and anchor points, and then the artistic concept was presented to the client. A coordination call with the CEO on August 27, 2026, finalized the sequence.
A slackline in the middle of the crowd
The show took place in the center of the hall, in the middle of the audience, rather than facing the audience head-on. The site survey specified a distance of 25 meters between the anchor points—more than the minimum 15 meters required for an acrobatic show—an anchor capacity of at least 4,000 kg, and a 3-meter safety corridor. On the day of the event, the line ran over A-frames that held it at head height, as close as possible to the spectators. For more details on this setup, see our acrobatic slackline performance for events.

The editing is part of the show
The written plan developed with Condecta consisted of six steps:
- The CEO finishes his speech.
- Two team members, dressed in black, step out of the containers and stretch a red ribbon across the exact location of the future line.
- The CEO cuts the ribbon.
- The music starts: the team sets up the line in 60 seconds, accompanied by a voice-over delivering the company's messages.
- The artist takes the stage: the show unfolds to music, without a voice-over.
- The artist hands things over to the caterer, while the crew takes down the set in the background.
The voice-over was pre-recorded in German, with a few words in French for our colleagues in French-speaking Switzerland. It also mentioned the integration of WL Bau, and a final voice-over repeated the company’s tagline. We provided the music, the sound system, and the wireless microphone for the speech, using equipment rented from Lumison.

Highlights: From the Red Ribbon to the Final Message
The red ribbon, stretched across the exact spot where the line would run, was intended to mark the official ribbon-cutting as the start of the show. The 60-second montage, set to music, was designed as a highlight in its own right: the audience watches the line appear right before their eyes.
In our photos, the artist—wearing a black vest and bow tie—performs a series of jumps, dives, and spins above the line for more than 6 minutes, beneath the overhead cranes in the warehouse.
According to the summary published by Condecta on September 3, 2026, the show wrapped up the day. In it, Condecta summarizes the show in five figures, each representing one of the company’s messages, with the last one representing “Wir für die Schweiz.”

Results and Impact: A Finale Praised by the Client
For Condecta, the acrobatic slackline show served its purpose: to wrap up Wikon’s opening day. “The goal was also to bring all employees together. And we wanted something special to close out the event,” explains Sarah Bertoli, Condecta’s marketing manager, in the video filmed after the show (comments translated from English). “It was truly something very special to watch.”
She liked “the combination of athletic performance and music,” and sees it as a reflection of where the company is right now: “Sometimes it’s a little risky, sometimes it’s a little challenging.” ” On the collaboration: “From the very first meeting, I was really impressed by how well-prepared you were. Overall, my experience was excellent: I really enjoyed it, from planning through execution.”
This format builds on other events we’ve helped organize: an acrobatic slackline performance for the grand opening of Forum Fribourg; a highline with a voice-over for DIXI Polytool’s 80th anniversary at another industrial site; and, in Sion, the ribbon-cutting ceremony at the Cour de Gare, performed high above on a highline.

Tips for Organizing a Slackline Show at the Grand Opening of an Industrial Site
- Conduct a site survey early on with the site manager. Clear height, lighting, distance between anchor points: plan on spending about an hour on site.
- Have the anchors inspected before finalizing the set design, whether they are on containers or on the structure of a hall.
- Don't rely on the darkness. With skylights, it's as bright as day: choose a show that works well in bright light.
- Synchronize the sequence with the speaker, and have a stand-in repeat the transition if the speaker is unavailable.
- Keep your messages short and to the point. During a standing meal, aim for about 10 minutes.
- Take everyone's language and image rights into account. A voice-over that includes a segment in the other language ensures everyone is included; agree in advance on which photos of staff to use.

Frequently Asked Questions: A Slackline Show for the Grand Opening of an Industrial Site
Is it possible to put on a slackline show in an active industrial warehouse?
Yes, provided there is at least 15 meters between two anchor points and an unobstructed space around the line. At Wikon, the site survey specified 25 meters between anchor points, a load capacity of at least 4,000 kg, and a 3-meter safety corridor, all within a warehouse filled with containers and inspection stations. Each project is analyzed in advance by our technical manager. The minimum distances are detailed on the page for our acrobatic slackline show.
What can you do when the hall is too low for a highline?
An acrobatic slackline show performed close to the ground. A highline requires a height of at least 8 meters, whereas at Wikon, the line was set at head height on A-frames. The performer moves around in the middle of the room, as close as possible to the audience. For another indoor example, see our corporate show at the Théâtre Marigny in Paris.
How can you turn a ribbon-cutting ceremony into a show launch?
By stretching the ribbon exactly where the future line will be. At Wikon, the plan called for two members of our team, dressed in black, to emerge from the containers with a red ribbon and stretch it across the hall. Once the CEO cut the ribbon, the music would start and the line would be set up. For another way to reinvent the ribbon, see the highline at the Cour de Gare in Sion.
How can we incorporate slackline setup into the staging?
By performing it sight-reading, to music, instead of hiding it. At Wikon, the routine was choreographed to last 60 seconds, while the voice-over conveyed the company’s messages. This format is typical of an acrobatic show: for events with a tight schedule, setup may take as little as 60 seconds, as noted on our page about acrobatic slacklining.
What kind of event should we organize to celebrate a merger or acquisition with our employees?
A collective, hands-on experience, rather than just another speech. For Condecta, which was celebrating the arrival of 25 employees from WL Bau, Slackline Events created a two-part show: a live montage accompanied by a voice-over that highlighted this integration, followed by an acrobatic performance in the midst of all the employees gathered together.
How can a German-French bilingual audience be included in a performance?
With a voice-over in the predominant language and a segment in the other language. At Wikon, where about 30 colleagues from French-speaking Switzerland were expected to speak to a predominantly German-speaking audience, the voice-over was recorded in German, with a few words in French. For another example of a custom-written script, see the voice-over for DIXI Polytool’s 80th anniversary.
