Taking Germany's two most recent and most "famous" public construction sites, one can get the impression that politicians should take their hands off any construction and leave it entirely to private professionals. The Hamburg Elbe Philharmonic Hall (wikipedia entry english and german) an the new Airport Berlin-Brandenburg (wikipedia: english and german) both are projects going pretty much wrong. In both cases, all estimates regarding costs, planning and finalization have been thrown over and changed massively.
Alone the Elbe Philharmonic Hall has doubled costs and construction time during construction. The Berlin Airport's construction disaster is in the german media almost every week with new delays and risen costs as well as chaotic conditions on site. Contractors have no idea what to do and where and when due to missing plans due to change of planning offices... Planned to open in june 2012, the opening date is now pushed to 2013....while costs are exploding and basic airport safety (fireproofing etc) rules have been neglected to great extends and need to be re-planned and built.
Do you have similar experiences about your tax money being spent by ambitious politicians? Or do you think prestigious objects like those two can never be built within time and cost frames?
Since yesterday, may 22, 2012, the old administrative building of "Werkzeug- und Maschinenfabrik Oerlikon" (MFO) is being moved 60 meters. The building is 80 meters long and weighs 6.200 tons and has been put "on wheels" for the move. Due to need of space where it had been standing for the last 100 years, the owner decided to move the whole structure. The project is described here on the owner's website: http://www.swiss-prime-site.ch/mfo/index.php
an animation of the move can be watched here: http://www.swiss-prime-site.ch/mfo/animation.php
This time, it is the leading precast concrete magazine "BFT International" (http://www.bft-international.com) that has taken the opportunity to write about our revolutionary product "Plicafix 200" for the repair of plywood formwork panels.
Today i drove past the rest station of "Deitingen Süd"
(at a swiss motorway) and pointed out the filigrane concrete roof structure to show my wife what really was avantgarde in the 1950s. Swiss architect Heinz Isler made this design his signature in the second half of the last century. http://de.wikipedia.org/wiki/Heinz_Isler
Repairing long scratches in Formwork panels has until now been a little complicated by placing the repair plugs overlapping. Emplica's new product Plicafix 200 is a long patch of plywood that can be used for the repair of longer scratches.
Here are a few images of how to do it:
long scratch (ca 15 cm / 6 in) in plywood panel
adjusting the stencil
routing with emplica drill Bit DB40Long
apply glue into edges
take a Plicafix 200 plywood repair patch
Place plicafix 200 on one side into hole
gently hammer plicafix 200 plywood repair patch into hole
Today i want to lead your eyes to a fascinating combination of classic and modern architecture. Daniel Libeskind has integrated a spike to the old building, which had been standing without purpose and empty for some 20 years. Now it reopened as the german military museum and is definitely worth a visit if you are around. The exposed concrete has been done very nicely and for once i have the impression that the combiantion of classizism and modernism has been accomplished in a not so eye-soring way. The formwork for sure is on the way to being complicated, but i guess it was more of a job for the statics engineers. Formwork was provided by Peri GmbH.
a few weeks ago i spend a cold and stormy fall weekend in our workshop fixing an old Paschal Raster formwork element. It was really really in a bad shap. Crap actually.
The result is not what we actually try to advertise, we are just using this formwork for marketing purposes and i thought i can also use some practical experience with how bad exactly formwork can look and how much work goes into fixing it.
First i took off the old plywood. Then the frame got introduced to my angle grinder. A few layer of paint after some foundation and then a new plywood board.
Since then, the element has seen a few pours of concrete again and is getting back to its original look soon...
Resheeting a framed plywood formwork panel can easily cost EUR 500 per large element of 6,5 sm. Repairing the (fin-) plywood sheet with the emplica system can save up to 25 per cent of the costs during the plywood board's lifetime.
Just imagine you bought a pair of USD 2.000 taylor made shoes in London and you throw them away when the outer sole has a hole. You wouldnt do that would you? You would bring them to a shoemaker and he would apply a new sole for a few dollars. The same calculation applies to the plywood. Why buy new when the old one can be used a little longer for high-grade exposed concrete pouring.
Please have a look at the table we provide for this very simple calculation.(click on image to enlarge).
The use of epoxy filler is on the way to an ideal repair, but damages that go through the plywood such as tieholes etc can not be repaired with filler. Also, the application and curing of filler-repair takes time and is harmful to your lungs.
Ideally, a repair system should reinstall a almost new condition of the board. this can be done with emplica plicafix repair plugs. They are made of finply plywood with a brown film coating and have the exact physical characteristics as the original plywood. Using a PU glue, the plicafix plugs are inseparably bonded with the plywood sheet. Plicafix repair plugs are made of PEFC certified european birch plywood.
In case you dont trust words coming from marketing departments, maybe this video can show how easy and quick the emplica repair plugs are set.
The repair system comes in a very useful steelbox as a starterkit with all necessary tools and a supply of plicafix repair plugs.
