Steelwork fabrication
Here's an image taken by Yusuke of the steel work being assembled in Nottingham yesterday. The partial frame is required to give the Fibre-C shell some additional lateral stiffness under windloading conditions. The frame will be painted and then delivered to site before the end of this week.

versions...
As any designer knows, you never get it right on the first try. However, reflecting on the path taken to arrive often illuminates the view at the final destination...
As things are gearing up for the upcoming DRL 10 Exhbition opening on Friday at the AA, we've been doing some back logging and digging up some of the various versions of the pavilion that have led us to where we are now.
The following images are from various stages of the development of the project and include early formal explorations of "skins", tests on sectioning and profiling arrangements, geometrical rationalization, and structural optimization. There are elements we have refined, developed, and improved. There are moments where we have had to sacrifice for the sake of constructability, efficiency, and structural stability. You win some...you lose some. In reverse chronological order...here's a few alternative versions of the pavilion...

laminations...
The second shipment of panels from Rieder has arrived. this means we will soon start to see the pavilion "noses" taking shape.
The "noses" are also where the structure is under the greatest stresses....in order for the material to take these stresses where the vertical load of the roof is being transferred to the horizontal deck, the ribs in these locations are triple laminated by bolting three sheets of 13mm Fibre-C sheets together.
The resulting slot is where the next profile will slide in and complete the laminated splice joint.

random site photos...
construction site/real-time exhibition space...the site gets a lot of attention from passers by...
special thanks to our sponsors...
dr. evil (under construction) and mini-me.
construction team schedule
a broken tooth...
the lasercut model has proven far more useful than the drawings...
post-it notes indicate profile numbers...
locations and positional reference are easy to identify...
view through the void of the bench...

Gasket detail - Condition D
Throughout the pavilion we have 4 different joint conditions, and 8 gasket types. Each of the joint conditions is determined by the assembly logic required at that location. Each of the gasket types is determined by the angle of intersection.
At the first phase of ground level assembly, we only have Condition D - Ground global profile (concrete) to ground cross profile (concrete), which utilizes gasket type 8, which is a flat 80mm x 50mm x 17mm EPDM rubber pad.
Joints on the ground members have no need for the locking gaskets to keep the profiles in place because gravity will work just fine, with the weight of the entire structure sitting on these guys, no one is lifting them off.
So, as a means of reducing costs, we opted for flat rubber pads which are glued in place at each notch to take up the difference in the over-size notch to make it a tight fit notch, but retaining enough fexibility for construction tolerances and to compensate for the fact that the intersections are angled.
After these pads have been glued into place, then the primay ground profiles can be inserted into the cross profiles.
Here's a detail, and some photos.
