After seven and a half years, I had my final exam as an undergraduate last Friday. As final exams go, it counted for a minute part of my degree – a far cry from my chemistry finals five years ago. Assessment at ENPC is continuous with marked courseworks and the occasional test. The “Conceptions Parasismiques” exam last week was only significant because it was my last engagement at the Ecole des Ponts, for tomorrow, I start my placement in a French company.
At this point it would be helpful to mention how I would be finishing my degree if I were back in the UK. In their final year, students at Imperial are expected to take on a full course-load of lectures and tutorials and at the same time, to conduct independent research that is to be written up at the end of the year, somehow in the middle of revising for final exams. In contrast, the system at Les Ponts, which I might add is a system which seems to be typical among other European engineering courses that I have heard about, requires that its students undertake a “projet de fin d’études”. Rather than being conducted in parallel with studies at the university, the PFE takes place in a company or a laboratory. In either case, the student is offered a placement during which they can undertake research at the same time as being involved with the day-to-day work of that enterprise. The placement is also paid, albeit at minimum wage level. Final year students are close to being qualified and so should know their stuff. This system offers them the chance to experience the work environment and also offers cheap labour to the companies involved.
Getting a placement is something of a magic art, and the following words are intended for the eight or so Imperial students coming to ENPC next year. What is not entirely clear with the PFE is whether it is the students who should be approaching companies with ideas for a project or whether students should be contacting the companies and asking them what they have on offer. One thing is for certain: if you tell an engineering company in France that you are from the Ecole des Ponts et Chaussées and you are looking for a PFE, they know what you are talking about.
In order to get my first experience of the professional world, and of speaking French proper like, I went to an event back in November called the Forum Trium, a careers fair where engineering companies and financial firms battle it out to solicit the interest of students from one of a number of grandes écoles in Paris. I turned up with the worst CV in the world, officially, and proceeded to distribute copies of it evenly across the hall. Most employers were looking for people interested graduate jobs, but my name was noted nonetheless.
I left the event no closer to finding a project. Term plodded on and the PFE slipped down my list of priorities until just before Christmas, when I found that a fair chunk of my French friends had found placements, and what’s more, they were going to be working on topics that not only interested me, but were with companies I would have dearly liked to have had a place with. I was no closer, however, to understanding how this application process should work. By the time term started in the New Year, I had landed on the idea of investigating the ways in which the carbon footprint of a building can be measured (more about this in the future). The project would have taken place at the local building research institute near Les Ponts. The whole project was conceived over a series of coffees with a couple of members of staff from the department. I was all set to accept when I received a phone call from a director of Setec TPI who invited me to an interview. It seemed that one of my awful CVs from the Forum Trium had made it onto his desk. He was looking for an English speaking engineering to join a team working in collaboration with an American architect on a new skyscraper at La Défense. Unshaven, I turned up that afternoon for the interview and was offered the place. In the space of a week I had gone from having nothing to having a choice of placements.
In the end I chose Setec. My project there will be an investigation into the role of skyscraper floor design in the overall stability of the building, both during construction and in service. But I didn’t choose this placement for the topic; rather I chose it for the experience of working in a French engineering office environment, and the opportunity to work on one of Paris’ most prestigious projects. If the last four months of study have been good for my French, I am hoping that this placement is going to do wonders.
In conclusion then, what would I recommend to next year’s students when it comes to looking for a placement? Well, I would definitely advise going to the Forum Trium and introducing yourself to as many companies as you can. Since I accepted my offer at Setec I have been offered two more placements (including one with SNCF that would have given me free TGV travel for the rest of the year!!) and both of these directly from the Forum. My other piece of advice is not to be scared to approach companies yourself and say, what project could you offer me. They expect to get calls from people like you, so you may as well get in where you want to before everyone else does. The chances are that the early you get involved, the more likely you are to get to choose a project that really interests you.

Paris is slowly encircling itself in tramways. The latest tramway to open, connecting the disparate ends of several metro lines is the T3, which skirts inner Paris’ southern border. As part of the project, the RATP commissioned a series of art installations on or in the vicinity of the route. So it was with travel card in hand that I went, albeit a little too late, one Saturday afternoon, to see what I could see, so to speak.
The trip became somewhat of an art-hunt for all I had to help me was a cutting from a newspaper giving some approximate locations, and a metro map. Unfortunately, I was not able to experience the murmuring benches as the park they were in had shut. And I simply couldn’t find the installation called “Mirage” (even though Mary swears blind that she did). One of the best installations, in my opinion, was realised using just light. Where the tramway passes under the TGV lines coming out of Montparnasse, the bridge’s beams and columns are lit up in orange and blue at night time reclaiming an otherwise threatening space (and showing off the beautiful metalwork on the columns which must have been lost in darkness even during the day).
The tour finished with a sculpture on the middle of the bridge. This installation is by Sophie Calle and Frank Gehry (with RFR as engineers) and consists of a twisted metal alcove or shelter with a telephone inside. According to a sign inside, only Sophie Calle has the number and she occasionally calls the number and to talk with whoever maybe passing by. The sculpture is a a shelter from the wind, a womb high up over the river, isolated, yet connected. If you have a few hours to spare in the south of Paris, I recommend taking the time to take the tram.

My mate Ronan is in a band called the Metropolisians. A month or so ago they won their heat in a battle of the bands contest for which the ultimate prize is a gig at the Elysée de Montmartre (Paris’ Astoria for the Londonners amongst you) and a record deal. With their brit-pop charm, stomping rhythms and oodles of charisma, they brought the house down with their second round performance last Friday night.
Appropriately for this second stage the competition was harder to beat, but not in terms of quality but rather the number of people clapping. Bands are rated on the basis of how many raised hands a man at the front can count at the end of each set. There were some pretty ropey high school bands and it looked at one point that one of these bands might have won, having brought half the high school with them for support. But in the end, it was the Metropolisians who got the last laugh with 189 votes to 99 for the band in second place.
Check out their website and if you hear “winkle-pickers” in one of the lyrics, it’s thanks to your friendly engineering correspondant in Paris.

We were recently asked in one of our French classes to write an article about a business in the style of short piece for a newspaper. The brief included nine words, some more obscure than others, that had to be included somewhere in the text. So for those who want to read a little story about a local bric-a-brac store look no further than below (the aforementioned nine words are in bold)
Le vide grenier de l’onzième
Il s’agit d’un magasin parisien qui existe depuis quarante ans dans ce quartier assez bobo. Sa vitrine est encadrée de bois très travaillé, avec des fleurs et des gargouilles gravées sur les deux côtés : un véritable bijou d’architecture. Derrière on trouve tout un bric-à-brac bizarre en provenance de quelques centaines de greniers anonymes, vidés grâce à cette entreprise.
La famille Tatattic habite à cet endroit depuis la fin du XIXe siècle : l’arrière grand-père Tatattic fut bachi bouzouk pendant la guerre de Crimée. Il traversa ensuite l’Europe pendant vingt ans avec sa carriole en tant que marchand de produits turcs. Il accumula un stock précieux, et quand il arriva à Paris, il vendit la totalité pour acheter un terrain de deux cents mètres carrés à côté de la Rue de Charonne. À cette époque, on était en pleine campagne, bien avant que la ville de Paris soit agrandie.
Pendant les années soixante et le réaménagement de la ville, l’arrière petit-fils Patrick Tatattic vendit le terrain et fit construire un grand immeuble avec un magasin au rez-de-chaussée. Il trouva l’amour avec une jolie danseuse qui s’appelait Kati. Elle fit le clown et le fit rire. Ils se découvrirent en plus une passion commune, les vide-greniers. Après trois semaines, ils se marièrent et commencèrent à explorer les greniers du quartier…
Quarante ans plus tard, ils travaillent toujours ensemble. Derrière le comptoir, c’est Patrick Tatattic, toujours chic avec son complet marron, qui vous accueille. C’est lui qui s’occupe de l’argent et du prix final. Pourtant, il ne connaît l’emplacement d’aucun de ses produits. Pour trouver quelque chose de précis, il faut s’adresser à sa femme.
Kati Tatattic n’est plus aussi belle que dans les années soixante, peut-être à cause de ces quarante ans passés cachée dans leur entrepôt (elle applique plusieurs couches de maquillage et sa peau fait un peu abricot fané). Elle est devenue vieille, comme les trésors que cette femme, sans enfants, surveille sept jours sur sept : c’est passionnant. Bien qu’elle ait quitté la scène depuis son mariage, elle danse toujours avec son mari. Si on regarde par la fenêtre quand il n’y a pas de clients à l’intérieur (c’est souvent le cas) on peut voir les deux en train de valser dans les couloirs.
C’est vrai que le stock est d’une qualité extraordinaire. On demande comment ces marchands peuvent sélectionner les meilleures pièces de chaque grenier au milieu de friperies, de valises et de la poussière qui n’intéressent personne. Leur secret: on dit dans le coin que Madame et Monsieur Tatattic ont un passe-partout pour tous les greniers de Paris, et qu’ils viennent en pleine nuit pour voler les objets de valeur avant que les propriétaires, qui dorment en dessous, puissent les vendre à un prix supérieur. Attention, peut-être sont-ils déjà venus danser chez vous.

It has been a gloriously warm day today in Paris. Too warm in fact. I wish more countries would follow Austria’s example and plant more wind turbine seeds so that they too can have fields full of wind turbines and we can stop this place that we live in getting any hotter!

There’s one thing that they do particularly well at the Ecole des Ponts et Chaussées (School of bridges and roads), and that is teaching how to build bridges and roads. I had my last lecture today in a course called construction métallique. It has been one of the hardest courses I have taken here but has also been one of the most enjoyable. As well as covering all the theory of how metal structures ‘work’ we have also looked at a range of specific examples, including the Stade de France, the pyramid at the Louvre and the Milau Viaduct. Today’s final class was given by an expert on metallic bridge construction and he had the following to say about America’s brutal motorway bridge design.
In France they keep it simple: put two metal beams across and then fill the gap between the two beams with a concrete deck. I say simple because it is very easy to work out how strong each beam needs to be, and that, after all, is what we engineers are paid for, right? In the USA however, things are not quite so straight forward. Famously low budgets for construction have lead to the use of lower quality materials and so there is a greater chance these bridge beams could fail. Each state has it’s own set of rules (which must make for nightmares when trying to build an interstate highway) but in all states, they are so worried about the strength of their beams that instead of allowing just two, they require five.
When I was living in the States, I noticed how brutal the motorway architecture could be. And now I think I know why. It is very difficult to make five enormous steel beams under a bridge look elegant. There is also no architectural budget, so all you get is the bare minimum. This five beam system also makes it very difficult for the engineer to work out what is going on. For reasons that I won’t go into here, when you have five beams under a bridge, it is complicated to calculate which is supporting the car and which is sitting there looking ugly. The ultimate irony is that if they spent a little more on materials, they would of higher quality and so they could use much less.

Check out my new website where I have posted a couple of movie clips. The first is a documentary that readers of this blog may remember I made back at the start of my semester at ENPC. I had been asked to give a presentation as part of a language class on any topic that of relevance to engineering. Weary of Power Point, I decided instead to make a short film that I then presented to the class. Those who have studied under the French system will spot the strategic use of ‘articulateurs’. I would only like to add that I hope my French has improved somewhat since those heady first weeks of term.
The other clip I made using some panoramic photos that I took at the top of the ‘Gherkin’ in 2004. I found a programme that would string them all together. I then used imovie to make the photo pan and uploaded that mpeg to the web. This process was a bit laborious. Can anyone advise me if it would have been quicker to create a photocast instead?

The Institution of Civil Engineers, in celebration of the 250th anniversary of the birthThomas Telford, has launched a blog in the name of that great Scottish engineer. The blog will contain extracts from diary entries and letters by Telford, the ICE’s first president. I have to confess that though Telford is credited with thousands of structures, a great number of which remain standing, I do not know enough about him. I hope that this blog will help me fill some gaps!
