yet more drains

/

 

This is not the start of an ongoing series but having posted a photograph of one drain then - a bit like with biscuits - it’s difficult to stop at just one.

The triangular drain is on the outer part of the paving at the centre of Kongens Nytorv where there is a chevron pattern in the stone setts. Diagonal lines are fairly common around the city as a way of diverting surface water towards a drain but here it becomes a giant pattern laid out around the central equestrian statue and the drain covers respect the pattern. They have a stylised version of the water of the harbour that is part of the city crest.

On Ofelia Plads the long drains running across the new public space have pierced iron plates and the inspection covers pick up the same size of small circle but they are reversed to form projecting studs so that the surface provides more traction when they are wet. With large building projects in the city it is rare to see evidence that the architects have turned to a junior in the drawing office and said … “I really don’t care … just pick anything from the catalogue that fits.” In Danish design every detail should matter even if most people don’t notice … even when they are standing on it.

The two examples from Ørestad on Amager are included - in part because they are interesting and in part because they are very much in the middle of a huge building site as this phase of new apartments is finished. Canals, trees and hard landscaping are in as work progresses so people moving in first have at least some semblance of a normal street outside their door.

These are not so much drains as iron inspection covers. HOFOR is the Copenhagen water company.

Looking on their web site recently for something else I came across an aspect of city planning that I had never thought about before. There was a heading and a link to a post on heat seeking drones and it turns out that on Amager the communal heating system has pipework that if stretched out would get to Rome and then all the way back. That is partly why there are so many iron covers with some for drainage systems and others for utility services like the communal heating. The drone is used to identify leaks in the system and it works best if it is flown when it is dark and the roads are dry and it has to be flown in co-ordination with the airport. So next time the flashing lights of a drone appear immediately above you they are probably not interested in you at all but what you are standing on.

Out near the beach on the east side of Amager there are large new apartment buildings that are going up and at an incredible speed because of the method of construction being used with large panels of preformed concrete lifted into place by huge cranes before then being fixed or linked together. 

Then, on the outer face, goes insulation and a veneer of brick in large sheets made in a factory …. and that is where I begin to have reservations.

Nordhaleøen

Research - to assess the possible impact of climate change on the city of Copenhagen - has concluded that rising sea levels together with changing weather patterns, could mean that storm winds could drive a tidal surge into the wide entrance to the harbour and cause extensive flooding in the centre of the city. 

Engineers are working on proposals for tidal defences or barriers that could be raised when necessary to keep storm water out of the harbour but Urban Power - a partnership of young architects in the city - have suggested that this is an opportunity to consider a more dynamic option … they have suggested that a man-made island could be constructed, rather than a single barrier, to protect the entrance to the harbour providing new land to develop and an opportunity to extend and link together, the infrastructure of bike routes, roads and metro links across the north and east side of the city.

Circular Economy

/
 

A major exhibition at the Royal Danish Academy of Fine Arts Schools of Architecture, Design and Conservation to show fourteen projects that offer new solutions and strategies for the development of new sustainable materials along with the development of new technologies, the exploration of new approaches to building and construction and the recycling or re-circulation of materials.

“The conversion means that we need to work innovatively and experimentally on the development of new materials and the recycling of old ones, while also using our knowledge to create solutions that people actually want to use. That is the way we work at KADK, so our research and the skills of our graduates can play a major role in terms of giving people a better life without putting pressure on our planet.” 

Lene Dammand Lund.

 

Through the Autumn there will be a series of open seminars to “draw on knowledge and experience from some of the world’s leading architects and designers in the field of circularity, who will be invited to talk about their work.”

 

the exhibition Circular Economy continues at KADK at Philip de Langes Allé 10 in Copenhagen until 3 December 2017

 

Nordhavnsvej and a northern harbour tunnel 

/

 

 

The planning proposals for Copenhagen dating from 1947, known as the Finger Plan, has served the city well as it expanded out to new suburbs in the north and the west but as the centre of the city becomes more intensively built up - for instance in the area south and south west of the main railway station - and as there is more extensive and more intensive development of the harbour and on Amager - south and east of the centre - in the opposite direction to the spread-out hand of the Finger Plan - then rather different and very ambitious engineering works for new infrastructure are needed. Extensive new road tunnels have been proposed to take traffic around the south side of the city.

a new road tunnel alongside city hall?

proposal by Tredje Natur for the new landscape of HC Andersens Boulevard
if most of the traffic is taken down into a new tunnel

possible routes for a new North Harbour Tunnel and a possible tunnel
from Bispeengbuen to Islands Brygge

 

A proposal for a major engineering project, to construct a tunnel down the west side of the historic city centre, is now in doubt.

It would take underground much of the traffic that now drives along HC Andersens Boulevard on the west side of the city hall and would have much more impact on the inner city than a north-harbour tunnel. 

It is also more controversial than the north tunnel because it would be expensive; because there would be complicated gains; some people would resent this as the first stage of banning traffic from the centre with all the restrictions that implies and there could be considerable disruption during construction work … although, actually, most people in the city seem to accept major engineering works as now somehow part of everyday life in Copenhagen with the extent of the works and the time scale for the current work on building a new metro line.

King's Garden pavilion

/
 

the King's Garden in 1784   

The temporary pavilion in the King's Garden in Copenhagen was opened officially yesterday, 18th August, and will now be used for events through the rest of the Summer and early Autumn.

In English architecture this type of roof truss is described as a "Queen Post" in part, I guess, because they are smaller than a "King Post" which is a single post immediately below the ridge or apex. Not that that makes any sense of the odd implication that there has to be two queen's for every king. It's also usual, except in a very very large roof, to have either two queens or one king. If carpenters did put in a king post flanked by queens then the queens often lean outwards and then are called queen struts.

Who knew the engineering of a roof could be such a minefield of social niceties?

Here there is no ridge piece but three long timbers or purlins on each side to space and support the 'common' rafters ... common here being nothing to do with their sense of taste or style but simply that there are a lot of them.

In the 17th century these gardens of the Rosenborg were enclosed and private, and then, as now, divided by avenues and walkways but with more of the spaces between laid out with planting and paths in geometric shapes. The aim was to delight and entertain the king and his court ... so the present pavilion also uses those ideas and those games with spaces and division to create different areas in each of the quadrants.

Knippelsbro - KULTURTÅRNET

/
 
 

At the centre of the harbour is Knippelsbro - the bridge between the historic centre of the city and Christianshavn. There has been a bridge here since the early 17th century when houses and warehouses were first built on land claimed from the sea in what was then a wide stretch of open water between the walled settlement of Copenhagen and the island of Amager.

The present bridge was completed in 1937 - designed by Kaj Gottlob and built by Wright, Thomsen & Kier with Burmeister & Wain - an engineering company whose works were just to the west of the bridge and whose ship yards were then to the east at Refshaleøen.

Earlier bridges had been at the level of the quay so had to be raised for most shipping to pass and were relatively narrow. As the port expanded, traffic crossing over and passing under the bridge increased so the new bridge, with a deck well over 27 metres wide, meant there could be tram tracks in each direction down the centre, wide lanes for traffic and wide pavements and, set much higher, with long approach ramps on both sides, the bridge only had to be raised for the larger ships passing through to the quays where the National Library now stands and to a long line of quays along the Islands Brygge side.

With its two copper-clad towers on distinctive stone piers, set just out from the quays, the bridge is an iconic and perhaps the iconic feature of the inner harbour.

Those towers held control rooms and sleeping accommodation for the men who supervised and opened the bridge but with the decline in harbour traffic the bridge is now controlled from the tower on the city side and the tower on the south or Christianshavn side of the bridge has been redundant for many years. A long campaign of lobbying and a serious programme of restoration work has lead to the south tower reopening as a new cultural attraction in the city. Visitors can climb up to the upper viewing gallery for amazing views up and down the harbour and in the process appreciate the quality of the well-thought through and careful design of the tower itself … now restored as one of the major monuments in the city from the 1930s that can be seen in its original form.

Some facilities were upgraded, including the fitting out of a new kitchen, so the tower can be used for social and cultural events including as a venue for meetings and meals and there have even been a couple of jazz concerts.

Dursley-Pedersen update

/
 

 

Back in May there was a post here about the Dursley-Pedersen bike that had just been added to the collection at the design museum in Copenhagen.

The bikes are still in production but I have still not seen any actually being ridden in the city so it was worth a trip over to Christiania - to the bike workshops of Christiania Cykler there - to see the current models.

I’m still not sure how people on these bikes cope with Copenhagen cobbles or is that the real benefit of that long low-hung hammock for a saddle - or cope with the pressure and rush of a Copenhagen peloton at full speed on a commute over one of the bridges and through the traffic. 

The options for different handlebars and modifications to the arrangement of the frame were impressive but I did note that none of the bikes in the showroom had that vicious-looking spike as all the bits of the frame came together above the handlebars in the early version … surely lethal if you hit a rut or a drain at the wrong angle and go hurtling over the top when the bike stops abruptly. Versions had the handlebars at the top so if they are straight then the posture is upright … sort of more Dutch … but some had handlebars that swept down like demented bull’s horns. Perhaps that’s the way to deal with pedestrians who try to cross when their little man is on red and your light is on green … 

Belvederebroen

/
 

 

A new bridge for cyclists and pedestrians was opened in the south harbour area of Copenhagen in October last year. 

Constructed over the Belvedere inlet - a narrow cut at the end of Frederiksholmsløbet - it connects Frederiks Brygge with Enghave Bryyge and completes a 13 kilometre circuit around the inner harbour for walkers, runners and cyclists and allows local cyclists to avoid heavy traffic on Vasbygade.

Designed by the architect SLA, this bridge is 25 metres long and is a generous width at 6 metres across. 

The sides or parapets are formed with large but thin tabs of steel that appear to have been folded upwards at different angles so they are close to vertical at the centre of the span but drop outwards and downwards in stages until they are almost horizontal towards the banks. It feels as if the bridge is open and welcoming as you approach and then gradually encloses you and protects you as you cross before opening out again as you reach the far side.

This folding is reminiscent of origami, of course, but it also looks a bit like the effect you get as pages of a book drop open.

There are three folds … the first just up from the bottom to form vertical at the bottom where the panel is attached to the side of the deck of the bridge so the next part is angled out. Then there is a fold up to form a vertical section that is more pronounced towards the centre and then, except on the outer tabs, a fold for a narrow almost horizontal section outwards to make what is, at the centre, the handrail of the bridge.

There is a striking contrast between the colour of the outside of the parapet in deep shiny iron-oxide red - rather like a Chinese lacquer red - and a matt grey inner surface and deck that is rubberised to reduce noise and provide better grip for bike tyres.

Sydhavnen - South Harbour - is an extensive area of new and ongoing redevelopment below HC Ørstedsværket - the power station at the south end of the harbour. The bridge is actually temporary and will only be here for about eighteen months before a permanent bridge - designed by the architectural practice COBE - is built to cross Frederiksholmsløbet to connect Enghave Brygge and Teglholmen.
