Fast Work by Slipform
AN apartment building of 25 storeys in Milwaukee, USA, has been erected in 28 days by a Swedish method of slipform casting. The method was developed by AB Byggförbattring, Stockholm.
Compared with a conventional rate of one floor in four days, the system cut building time by 14 weeks. Cost savings for the $US3.5 million project are said to be about 20 per cent.
Construction of the building, Bayview Terrace, included flooring as well as the concrete framing and walls. Pioneering work was also done in slipforming exterior columns and exposed concrete spandrels. Even the chimney and incinerator chute were slipformed.
The slipform comprised a huge double-decked work platform extending over the entire building. Riding up with the work platform was a climbing tower crane that hoisted precast beams, floor forms, reinforcing, inserts and other slipforming materials.
This Swedish system has been used once before in America. A ten-storey building in Memphis was erected in only seven days.
German Ideas for Tower Houses
· ·
A POSSIBLE solution to the problem of how to give flat dwellers the facilities enjoyed by house dwellers has been produced by a Cologne architect, Mr. Josef Kupper.
His idea is for a multi-storey circular tower made up of many individual houses. Some 120 sq. yd. of flexible living space would be allocated to each dwelling.
The tower of houses would cover a site area of 4,800 sq. yd. and would attain a height of 315 ft. It would contain 250 detached houses and two family houses.
Its 25 floors are designed in such a way as to enable all dwellings to receive a maximum amount of daylight. Each unit is well insulated against noise and is completely self-contained within its own lot.
There are four vertical shafts facing the well. Each has one staircase and two lifts.
At the highest floor levels are 40 apartments, three storeys high, and above these on the topmost platform are two large swimming pools and a restaurant.

and a Town in a Tower
EVEN more spectacular is proposal by another German architect, Mr. Robert Gabriel, for a "town in a tower," to be built near the capital of Bonn.
Three times taller than the Empire State building, this tower would have 356 floors. It would house 25,000 people in 8,000 apartments and would include all amenities such as shops, restaurants and theatres.
By putting a town in one building with a base diameter of 900 ft. a large expanse of land would be opened up for parks and agriculture. Parking for about 4,000 cars would be underground.
Mr. Gabriel claims he could finish his plans in three years and the building could be completed by 1975.
International Meeting
in Paris
ArchitectuRAL Education is to be the theme of the eighth biannual congress of the International Union of Architects to be held in Paris from July 5 to 9.
Delegates will take part in working group sessions under three headings: the general education system, architectural training courses, and post-graduate education and experience. Simultaneous interpretation is being arranged in four languages English, Spanish, French
and Russian.
Two architectual students from each national section will attend the congress without paying fees. These are being selected by the national sections, where possible from the winners of schools competitions.
Registration for the congress closes this month. The secretariat is at 15 Quai Malaquais, Paris VIème. Tele- graphic address : Malarki-Paris.
