In October 2013, project engineering began for the Partille Arena and in December of the same year, 500 six-year-olds turned the first sod. Their enthusiasm mirrors the project: All those involved in the Partille Arena feel that this is a type of project that one is involved with just once in a lifetime.
Skanska won the assignment through a public tender, thanks to a cost-conscious proposal that met all functionality requirements. The project is a design-build contract, and the ordering party is Partillebo, the municipality’s property company. Many competencies within Skanska are involved as a result of the facility’s size and complexity.
In January 2014, we began to decontaminate the old industrial site. Luckily, the ground was less contaminated than expected, permitting us to move rapidly on to site preparation work.
Vibrations from “bouncy” spectators
An arena must cope with vibrations from bouncy spectators. We conducted a detailed dynamic analysis and elected to use point-bearing concrete piles. The upper part of he ground is clay, which is common in the Gothenburg area. After this, there is non-cohesive soil consisting of stone or gravel, and then furthest down there is rock. We set the piles in the non-cohesive soil so that they form a firm foundation for the arena.
But it isn’t just the arena that is significant in terms of vibrations. The houses built nearby may be built in a manner that reinforces or dampens the vibrations from the arena. This is a matter of the rigidity of the building. We have calculated various data that present builders with the conditions to ensure that they can construct buildings in the correct manner.
Highway entails requirements for the building carcass
The next step is to lay a concrete base. Subsequently, we will build the carcass. The nearby E20 highway imposes certain requirements in respect of the carcass. This highway is used to transport hazardous goods, such as petroleum and diesel. We have dimensioned the building to cope with any explosion.
“The building reflects a special design, like a loaf of bread. The section that faces the highway is a concrete wall that then transforms into an arch-shaped roof. We’ve designed the walls and roof to ensure that they can cope with an explosion,” says Jonas Jonsson, Project Manager.
The required flexibility of the building was a test for the designers. All the operations in the building impose different requirements in terms of design, sound, ventilation and lighting. The requirements are quite frequently conflicting, so you have to find the optimal solution. A concert may be held in the main auditorium, while people sit and work in the office section. An important bowling match and handball training must never disturb each other.
An arena requires a great deal of electrical installations. Apart from audio-video, there is also the matter of fire alarms and burglar alarms. Everything must function in the optimal manner.
We’ve worked closely with architects and subcontractors to find optimal solutions. All parties are encouraged to express their opinions at an early stage so that we can gain from their experience.
Flexibility is not only about activities in various halls not interrupting each other. It also involves the capacity to convert rapidly a space from one event to another. During the day, people can watch a Sävehof game; subsequently, on the same day, the seating is removed and placed in front of the stage for a performance by “Kulturskolan” (Culture Academy). This has created an affinity between the spectators and performing artists.
The arena is expected to be complete in July 2016. The Partille population will gain access to their new rendezvous, a living arena and a landmark in this expanding municipality.
