based on arc magnet supports, $2-3k ea. à $32-48k
better estimate will come after design work started.
1 girder has 5 QF’s and 5 QD’s requiring 40 coils à $40k
Installation takes approximately 8 man-weeks per girder (based on our knowledge that bends take 6 man-weeks per girder).
At $60/hour à installation per girder is $19.2k
The coils that are removed are then refurbished with new terminations and jumpers so that the next girder can be replaced in a subsequent down-time.
The present coil block fittings are brass (easily damaged) and are either soft soldered (cracks easily) or threaded with PTF sealant (corrosion damage). New design uses brazed stainless fittings.
Refurbishment costs for these girders amounts to:
320 termination blocks at $25 ea. à $8k
120 jumpers at $20 ea. à $2.4k
$19.2k x 4 = $76.8k installation
+$40k for the Y-girder magnet supports
