Review of Facilities/infrastructure Progress
6/2/97
D. Beavis

I)Magnets
	D1:
	First coil has been tested and second coil is being fabricated.
	Prints for the iron are being copied and should be sent to the
	shops by the end of the week (6/6/97).
	D5:
	Iron parts are fabricated and as a secondary job being fitted to
	the existing core.
	First coil has been wound and should be potted soon.

	Engineer will travel to Calif. in about two weeks to inspect
	the D1 and D5 coils.

	D3:
	Coil design are done.
	Iron design is done and just needs checking. Checking delayed
	while an issue for the septum plate is considered.

	D4:
	Final choice of a specific 18D72 magnet has not been made.

	D2:
	Progress continuing to finalize design parameters.

Platforms:

	Plan views and elevation views have been done for the mid-rapidity
	and front forward platforms.  Some layout numbers are pending from 
	the experiment for the back FS platform.

	It is expected that only the motor, pivot bearing, and wheels 
	from the existing E866 platform will be used for
	the mid-rapidity platform. The Henry Higgins platform is not 
	considered useful for BRAHMS. It is unlikely that the Moby Dick
	platform can be used due to the smaller floor to beam height
	distance.

	It is not expected that substantial engineering and design will be
	need for the platforms. This needs a refined evaluation and the 
	possible funds saved should be used where need to maintain
	schedule.

Infrastructure:

	Mezzanine
	A new vendor quote of 20k$ for the mezzanine is in with the appropriate
	grating and support columns. The vendor will supply design prints and
	cost could increase 2-3k$ if it is evaluated to be union work.
	The building modifications of removing/moving the air handling, moving
	the lights, and adding th access door could start soon. Funds are
	sufficient this year to complete this work.

	Water System
	Options are being considered for the water system.  Concerns of 
	potential environmental issues are being folded into the design
	parameters. D. Beavis will contact RHIC about whether the system
	needs to be considered for potential activation. Goal is to
	develope a specification for outside firms to bid on including the
	engineering and design. 

	Power
	The design for the power distribution is expected to start in
	August when the RHIC designer becomes available. 

Hardware

	A list of hardware to purchase before the end of the fiscal year 
	needs to be developed. These items should be purchased if sufficient 
	funds remain and include cable tray, AC disconnect switches, and other 
	items which may allow early installation next year and avoid waiting for
	parts delivery.
