The XXL Workshop is an elective course held at the Faculty of Architecture of Delft University of Technology. It is concerned with the design, computation, engineering, and production of a horizontal large span building structure. This design process is done as a collaborative digital design in a multidisciplinary group of students in which each student has his/her own different responsibility. The collaborative digital design requires an integrated 3D approach based on BIM (Building Information Modeling) principles, performance analysis, and file to factory processes.

Reviews. "The Expert Formerly Known As The Architect" [Kas Oosterhuis]

Friday 18th March students’ works reviews. From all of us, thanks for their contributions and comments to Prof. Antonino Saggio and Prof. Kas Oosterhuis, who also proposed and promoted the initiative – to Prof. Patrick Teuffel, Prof. Ulrich Knaak, ir. Jelle Feringa, Dr. Rudi Stouffs, ir. Andre’ Chaszar and others for attending and contributing to the event. Among the many discussed points, the question on the role of the Architect in the current and future interdisciplinary team work emerged as key topic. Addressing the attention to all students for the great work they are doing: see following presentations.

Week 4 - general tasks

Dear students,

During the first 3 weeks, the course encouraged each group to broadly explore various design directions. The presentations on the 17th of February aimed at selecting one clear design direction for each group. We hope the comments helped you in addressing one specific design direction, which should have few very well focused aspects. It is time now to focus on the selected aspects only, by narrowing down the design exploration and strongly reducing its complexity. Please, from now on, you should develop your design by focusing only on the key drivers of the design direction you have chosen.

Just to further remember it, the design drivers of your project are meant to address the 2 main design tasks: the 24/7 use of the stadium by means of adaptability (reconfigurability) and the sustainability (mainly passive and active use of renewable energies). Each of you within the team (4 disciplines) has to work to achieve the 2 tasks by further developing your design concept based on the few selected clear design drivers you have chosen.

To reach this goal, it is time now to start verifying the performances you are aiming at, by means of cycles of performance simulations - feededback to your design solutions, as a support of your decision making process. Particularly, here following some specific tasks you should aim at this week:

1) Simulation support and design development - with iterative design development using numeric simulation and development cycles
2) Reinforce the integrated multidisciplinary design
3) Make physical working models when they support your design process

At this phase, your own role within the team has to be even more specific than before - please, each of your should act as responsible of his/her field.
For the computational design experts, this week is a crucial step of the process. Please, based on the interdisciplinary discussion with your team, select/identify meaningful independent parameters of your geometry, and set the loops of the needed performance analysis over the parametric models.

Let me know if there are doubts,

1 Feb 2011 - Opening - Themes of the Workshop, student teams, schedule

The design focuses on a large span structure for a stadium, De Kuip in Rotterdam. Additional information on the location is provided at the beginning of the course, through a guided visit on the site and lectures on the subject.

The design and research objectives can be subdivided according to six main disciplines, as following. Additional information is provided at the beginning of the course based on lectures focusing on each single discipline.

Architectural Design
Instructors: K. Oosterhuis; H.H. Bier; ir. Jelle Feringa
Design of a reconfigurable* Stadium able to satisfy a functional program with continuity during 24 hours per 7 days a week; both occasional events with exceptionally high number of spectators and minor events with limited public need to be held by guaranteeing the absence of empty seats/areas for public. Design of a sustainable** Stadium. Design of a performance-driven Stadium, integrating inputs from the different disciplines since its early concept. Expression of an individual, distinctive style.

Cladding Design and Construction
Instructor: ir. T. Klein
Design of a performative and sustainable** cladding system. Design of the cladding as integral part of the reconfigurable architecture and eventually adaptive* itself, when needed.

Structural Design
Instructors: J. Paul; ir. A. Borgart
Design of a structurally innovative, efficient, reconfigurable* and sustainable** structural system for a large span Stadium.

Digital Design Management
Instructors: Arch. M. Turrin; ir. S. Mulders
Conception and development of a digital and computational strategy to create a multidisciplinary design process (including strategies for digital modeling, loops between geometry and performance analysis, file exchange and archiving, integration of prototyping, etc.).

Instructors: P. Teuffel; Dipl.Ing. F. Heinzelmann
This discipline is transversal to architectural design, cladding and structural design and is integrated in all of them; moreover the digital design process has to support achieving the tasks for adaptability. Adaptability is possibly intended from the large scale of the whole reconfigurable stadium to the small scale of its materials. It is meant to support achieving the performance requirements (functional, energy-related, structural, etc.).

Instructors: A. van Timmeren; M. Tenpierik; Ing. A.K. Lassen
This discipline is transversal to architectural design, cladding and structural design and will be applied to all of them; moreover the digital design process has to support achieving the tasks for sustainability. The Stadium is designed as an Energy producing building, based on renewable sources. The design aims at reducing Carbon emissions for use related flows and materials (far going, aiming at neutrality when possible).

The design process is developed based on the interdisciplinary activity of a design team composed by 4 students. The work is structured according to four disciplines, corresponding to four roles in the team. The whole team and the shared goals of its activities are described in the first table. The specificities of each discipline are described in the course guidelines.
