Flamingo Hotel expansion

Flamingo is the largest indoor water park in Finland and a massive entertainment centre with lots of visitors even from afar.

The Break Sokos Hotel Flamingo embrace the increasing demand with a new steel-frame building with 232 rooms. Sweco has been in charge of the expansion’s structural engineering and information model coordination.

The hotel expanded to meet the region’s developmental requirements and reinforce Flamingo’s role as a centre for entertainment. The wing-shaped, bright red and spectacular hotel building has a surface area of approximately 9,700 floor square meters, making it the largest hotel in Finland.

The shape of the building is both interesting and challenging. The entire span of the building is curved, narrowing towards the east and ending at a round staircase tower.

Adaptable facilities

The hotel floors’ frame consists of a combination of steel columns, steel beams and hollow core slabs, which supports the adaptability and efficient use of the building. This enables the construction of light partition walls that can be easily modified.

The initial design of the project included WQ beams. In the tendering stage and based on the initial information provided by the client, the steel frame supplier Peikko drew up an alternative solution of DELTABEAMs. Once Peikko had secured the contract, it used the initial information to create final measurements for the beams and create engineering design plans. The connections between pillars and beams were designed by Sweco.

“The majority of the architectural modelling has been lifted on top of a massive cast-in-situ slab-beam framework, and it is supported by reinforcing wall structures and a grid of beams with wider gaps than in the upper floors. The slab-beam framework functions as a sort of load-bearing bridge deck structure. On top of this structure are the composite pillars upon which the DELTABEAMs, as wide as hollow core slabs, lay. The curved shapes are primarily manufactured by using straight beam moulds, which was one of the deciding factors behind DELTABEAMs. The façades are supported by the beams. The underlying idea was that the beams should not have elevated ledgers, creating more vertical space and making the building service system installation work easier,” says Sweco’s Ville Tarvainen, in charge of the site’s steel structure design.

Information models bring operators together and make design and construction more efficient

Several operators have been working together according to a joint model is increasingly common in construction. The model made cooperation more efficient and quicker. “At the site, we used the Tekla Model Sharing tool, where the actual model is stored on a cloud-based server, where different users can access it. In this project, both Sweco’s and Peikko’s modellers worked according to a single model, making exchanging data effortless and harmonisation and inspection easy,” Tarvainen continues.

Peikko agrees with this view of the information model. “We designed the DELTABEAM by information modelling with Sweco, working on the same model. This feels great, because we are constantly able to track the progress of the design and see what changes are required and being implemented,” adds Elina Hietanen, Project Specialist at Peikko.

Break Sokos Hotel Flamingo is the largest hotel in Finland with its 539 rooms. The expansion construction is completed at the end of 2018.
