Step one:
Steel has been erected (part of the roof steel can be seen in the model on
the table in red), and the metal deck has been installed. The
work of the stucco contractor, the sheet metal contractor, and the roofing
contractor now need to be coordinated. All the components to be installed
by these three contractors are on the table next to the roof model. To the
left of the model, the stucco soffit is shown in white. In front of the
model, one can see the electronic model of the double gutter. To the right
of the model, insulation layers, the ice and water protector, roof tiles, and
various assembly pieces are stacked up. Martin Fischer (white hardhat) and
Chris Marolf (blue hardhat) are now trying out an assembly sequence.
Step two:
The roof insulation and the ice and water protector have been placed on the metal
deck. Using the wand (Polhemus stylus),
Chris is picking up a strip of metal which
will act as a kicker for the first row of tiles (the component that is
touched or moved turns red). In front of Chris, one can see the
menu-driven interface (in light blue) that allows users to move and rotate
the model, and to zoom in and out.
Step three:
Chris has "installed" the kicker and the gutter assembly piece at the roof
edge. He is getting ready to place the roof tiles (which have turned red
since Chris is touching them with the wand).
Step four:
The tiles have been placed, and have reverted from red
back to their model color blue. The stucco has also been placed. Martin
is moving the gutter into place.
Step five:
The roof is fully assembled. The whole assembly took just a few minutes
and can be repeated easily, or an alternate sequence can be tried until
agreement about the best assembly and installation sequence between all
contractors has been reached.
Step six:
Chris and Martin have rotated the model to inspect and discuss the roof
assembly plus the supporting structure and fireproofing.
