Paving the way for a sustainable working city
Striking, inviting, inspiring, multifunctional, flexible, healthy, and sustainable. With these characteristics, the office and multi-company building, The Joan I, fulfills the pioneering role and exemplary function for the further future development of Werkstad OverAmstel, the redevelopment of the existing Amstel Business Park in Amsterdam South.
The Joan I has 24,000 m2 of office, business, and public space with ample parking in the neighboring car park, The Joan II. The design of the pair of buildings is in the name of OZ Architects. The building's transparency, openness, flexibility, and sustainability are facilitated by the skeleton-shaped supporting structure containing hollow-core slab floors and spatial trusses in the facade zones.
The district of Ouder-Amstel wants to change the monofunctional and quiet Amstel Business Park in Amsterdam South into a lively, multifunctional, and future-proof 'Working City OverAmstel.' The area, sandwiched between the A10 and the A2, is destined to become 'the place to be' for a wide variety of companies and organizations from numerous industries, from IT & multimedia and mobility & logistics to food & hospitality and fashion & design. With such a diverse population, the working city is the place to sustainably create, innovate and produce together.
The Joan I acts as an ambassador for the implementation of this vision. As one of the first new construction projects during the area's transformation, the nine-story building shows how you can effectively combine work, comfort, health, and sustainability.
The transparent skin of the building and high ceilings provides ample daylight and a splendid view of the surroundings. By shifting the floors relative to each other, a comfortable indoor-outdoor space is created on each layer on one side and an overhang on the opposite side, giving the building mass an articulation. Vegetation has been applied around the lifts and stairwells on every floor.
In addition to these 'green lungs,' the building has climate ceilings, a roof covered with sedum, a thermal storage system, and PV panels on the roof for a sustainable energy supply.
The Joan I is prepared for changes in use and functions. The floors, each about 2,600 m2, can be arranged entirely according to the tenants' wishes. This can be done both horizontally and vertically. Connecting two floors via a new indoor staircase is also an option. The building will be multifunctional from the moment of completion.
The Joan I measures a total of 24,000 m2. About 10,000 m2 is intended for offices, nearly 12,500 m2 will function as a workshop or studio for companies in the creative industry, and about 4,000 m2 will serve as meeting facilities. The plinth will house a publicly accessible catering facility of approximately 500 m2, an inviting meeting place for relaxation and interaction.
Sustainable and healthy working environment
In The Joan I, health and comfort are paramount. The design by the architectural firm OZ is characterized by a glass facade with steel crosses and an open appearance. The facade's glass ensures a lot of natural light and a wide view of the outside. Each floor has vertical vegetation, which is fed with collected rainwater. These 'green lungs' promote the well-being and productivity of users. The Joan I responds to the increasing demand for a sustainable and healthy working environment in an easily accessible location.
The Joan II
Opposite The Joan I, there's The Joan II, an efficient and stylish parking house that fits seamlessly with the public space and architecture of The Joan I. The building contains a green facade made by stretching a wire net to support planters and lots of greenery. The installations of the three-story parking house are fully fed from the sustainable (main) installation of The Joan I. This parking house of approximately 11,000 m2 offers 376 places for cars and 155 for bicycles, spread over the three above-ground floors. The installations of the Joan II are fully fed by the sustainable main installation of The Joan I.
Visser & Smit Bouw came up with a new development for this project. In the context of building more efficiently and reducing unnecessary work, they thought that it should be possible to realize a project without using 2D drawings if, at the same time, the 3D model is of sufficient quality and level. To discover this step by step, they devised a pilot that was applied to Joan I. In concrete terms, this meant:
- As on any project, we have a material container at work on the construction site which is centrally placed and can move with each floor.
- In the material container, which moved along with each floor, a PC was placed on which the Solibri model (in slimmed-down form) was available.
- The Visser & Smit foremen were trained in the use of Solibri to operate the model and provided the material container with simple instruction cards for using the software.
- The foremen worked on the basis of (approved) models. They had to extract information from the model, measure the dimensions and make cross-sections themselves.
- The models were approved by the work preparation department and recorded in a separate Excel document. This method clarified which model was released, by whom, at which time, and for which parts.
- As a backup, the chief executive officer had the drawings, which were approved by the customer, available in the shed. If data from the model was insufficient, the correct parts could still be realized. The progress of the project was monitored on a fortnightly basis. The goal of this pilot was to work towards 'drawingless' construction on future projects so that the drawing would no longer have to be made at all.
- Data exchange using IFC, BCF, and source files within the framework of the OpenBIM method.
- Issue Management System BIMcollab.
- DocStream exchange platform.
- Spare parts calculations must be made in accordance with the USO.
- Responsibilities according to demarcation.
- Required data according to the BIM Execution Plan.
- NL-SfB coding.
- Internal model validation with Solibri.
