Lecture: "Transformations"

Alison Brooks Architects is one of the UK’s most highly awarded and internationally acclaimed architects office. Since founding the practice in 1996 Alison Brooks has emerged as one of the UK’s most inventive architects with works encompassing urban design and housing, higher education buildings, private houses and public buildings for the arts. She is the only UK architect to have received all three of the profession’s most prestigious awards: the RIBA Stirling Prize, the Manser Medal (twice), and the Stephen Lawrence Prize.

Alison Brooks’ unique architectural approach springs from invested research into the specific geography, climate and cultures of each project so that their design solutions emerge as both unique and relevant to the constituencies they serve. This is exemplified by their recently completed Cohen Quadrangle at Exeter College, Oxford. The first to be designed by a female architect, this building demonstrates the conceptual rigour, sculptural quality and ingenious detailing that is her practice trademark.

Ceri Edmunds is a graduate of Cambridge University and Harvard University, where he received a Masters with Distinction in 2013. His thesis research and design project won the Clifford Wong Prize in Housing Design. While studying, he also assisted with the teaching of two Harvard design studios. Ceri gained his RIBA Part III at the University of Westminster in 2016.

Ceri joined ABA in 2014, having previously worked for the office from 2007-2009, and for the summers of 2010 and 2011. Ceri has had a
key role as a designer in competition winning schemes, such as; North West Cambridge Development ‘Knight’s Park’; Kings Cross
Development ‘Cadence’, Exeter College Cohen Quad, Oxford, the University of Northampton and an Art Cenre in Cambridge. More recently, Ceri was a design lead in the shortlisted London School of Economics Global Hub design proposal.

Ceri has worked on a wide variety of projects at Alison Brooks Architects, including Newhall Be, Windward House, Audi Urban Future Initiative, urban extensions and mixed use developments. Ceri has also taken responsibility for delivering the practice’s 4 installations at the Venice Architecture Biennale: Home Ground, Future Assembly, ReCasting and City (e) State. While in the USA, he was employed by
New York offices Weiss/Manfredi and MOS Architects, where he worked on the renovation of an opera house and a number of
experimental houses.

Stuttgart 21

About the project

This year's focus topic ACO On Site was dedicated to one of the largest construction projects for public rail transport in urban areas: Stuttgart 21, the project for the new Stuttgart railway station.

The planning phase for the Deutsche Bahn project began around 25 years ago. With Angelika Schmid from Werner Sobek AG and Michael Rathgeb from ingenhoven associates GmbH, two experts from the major lead offices provided insight into this gigantic and very complex project in which also ACO is involved.

The Stuttgart-Ulm railway project, known as Stuttgart 21, is the largest public rail development project undertaken in Baden-Wuerttemberg since the 19th century. It is the complete reorganization of the Stuttgart rail hub and will help to significantly reduce travel times for long-distance and regional traffic. The airport will be connected to the long-distance railroad, which will considerably relieve road traffic.

The future railway station will enable many new transfer-free connections in regional traffic and thus also relieve the public transport with its daily high passenger volume. Compared to the former terminus station, the new railway station can handle significantly more train traffic.

To be built:
- four new stations
- 57 kilometers of new rail tracks, which will travel at speeds of up to 250 km/h
- 59 kilometers of tunnels / 16 tunnels and culverts / 44 bridges

The central structure of the project is the future main station. Its roof, designed by ingenhoven architects, consists of 28 chalice supports - a concrete shell structure that has never been built before. Up to 350 tons of steel and 685 cubic meters of concrete are used for a chalice with a diameter of 32 meters. Large glass domes on 23 of the challice supports provide daylight in the platform hall. The geometry of the new underground station is complex and places enormous demands on all those involved in the design procedure.

The Stuttgart-Ulm rail project currently provides jobs for an estimated 6,000 people, for example as miners, geologists, iron benders, planners, engineers, merchants or biologists.

Stuttgart 21 is not only of great importance for Stuttgart in terms of transport, but also in terms of urban development. Stuttgart 21 offers space for two new neighborhoods in the middle of the city, 100 hectares are available for urban development, 50 hectares are planned for living and working, the park will be extended by 20 hectares and, in addition, ten hectares are planned for the construction of green spaces and public squares.

Jan Schmitz, ACO Passavant Detego

At Stuttgart 21, ACO has been commissioned to supply large floor gates for escape in addition to floor drains, lifting stations, grease separators and open-space drainage. This order is the largest to date in the history of ACO Passavant Detego, the specialist for special manhole covers and market leader in this field. The dimensions of the products are also impressive: the floor gates measure around five by six meters and weigh more than ten tons each.

The stainless steel giants will form an important part of the station's security. In an emergency, for example in the event of a fire, they will be raised by hydraulics to clear escape routes. In addition, they can also be opened manually via a buzzer.

Organizationally and logistically, the project is a big challenge. For several years, research, preparation, and planning have been carried out for it in Mülheim-Kärlich, where the technical office and the production site for custom made covers is based. The performance specification comprises more than 100 pages, and the requirements for hydraulics and control of the heavy gates are particularly high. All the gates will be produced and installed one after the other by the end of 2023.

Jan Schmitz, Head of Sales Technical Covers at ACO Passavant Detego, reported live what exactly these covers are about and what challenges they have to face.

Speaker: Jan Schmitz | ACO Group
Muehlheim-Kaerlich | Germany

Jan Schmitz, graduate industrial engineer and Head of Sales Technical Covers at ACO Passavant Detego began his professional career in Karlsruhe when he started studying at the Baden-Württemberg Cooperative State University. After completing his studies and a short excursion at BIRCO as a property manager, Jan Schmitz started at WAREMA Renkhoff SE as a trainee in sales.

After only two years, his potential was recognized and he was offered a position as branch manager in Hagen and the surrounding area. A few years later, he was able to take off as sales manager at Europe's leading manufacturer of technical products in the sun protection sector.

After eleven years, Jan Schmitz changed companies to expand his professional development. He used another three years to get to know the construction sector better until he was hired as sales director for ACO Passavant Detego in August 2021. He is responsible for the sales of "custom made covers". The focus of his work is to specifically adapt the products to customer project needs. His focus is on the DACH region and international expansion.
