About Cranes

• Cranes >100t are custom engineered = $$$.• Cranes <100t are off the shelf standard = $.• Cranes have a duty rating = +/- $.• Crane support structure cost scales with capacity.• A 400t crane will require a support structure and

foundation on the scale of a steel mill = $$$.

About Curtain Walls

• It has been proposed to use a single collider hall separated into two detector regions by a removable 3m concrete wall.

• In order to accomplish this, a combination of stacked concrete blocks topped with a retractable curtain wall will be required.

Amann – 09/12/06

PEPII IR2 Curtain Wall• Curtain walls need a runway.

• Runway rail is embedded into concrete support.

• To maintain small gap between curtain wall and the IR hall surfaces the bridge crane runway should be embedded and not a freestanding steel structure.

• The above will require a IR hall with a robust concrete structure.

• In general, a curtain wall will require a smooth finished IR cavern to maintain a small gap between the curtain wall and the IR hall walls and ceiling.

Other IR Hall Needs• Compressed Air - need required PSI, CFM, moisture content, locations

• H2O supply – potable, non-potable

• AC Power Distribution – welding sockets 500 amp, other 480/240V sockets.

• Machine Shop, Welding Area, and Tool Crib

• VESDA and Fire Suppression

• IR Hall Lighting

• O2 Deficiency Monitors

• Clean Room – how big, what class?

• Materials Storage Area

Amann – 09/12/06

Questions to Think About

• IR Hall - rectangular box or curved cavern?

• Surface assembly building - size and orientation?

• BDS tunnel height above IR Hall floor – what constrains this?

• Curtain Wall – required thickness?
