	Number	Description
1.5	Muon Subsystem
	Cost of labor and materials needed to install the US ATLAS Muon system deliverables. There are three deliverable object 
	types covered under this WBS; 240 - MDT chambers, 32 - CSC chambers and 80 - Global Alignment Bars and their 
	associated monitors. The installation work will be conducted starting in Q2 of FY04 and extending through the end of CY05
	 (Q1 of FY06). Installation costs are primarily labor for experienced mechanical technicians who are responsible for: staging
	 the chambers and alignment components prior to installation; conducting the installations;  followed by precision location 
	adjustment (~ 3 mm) of each object in their supporting structures . The installation crew is supervised by personnel 
	supported by the U.S. Base Program. 
	
	For optimal efficiency it is planned that the installation crew work will work as a unit of approximately 6 FTEs   (2 FTE- 
	base, 4 FTE- project). The crew concentrating sequentially on each installation task, such as mounting the CSC chambers
	 on the Small Wheels, then moving to the next task.
	
	The integral FTEs over the entire installation task of approximately 2 years duration is 6 FTEs.
	 
	Of the 6 FTEs, 3 of US origin:
	
	     2 - Senior Physicists - An Overall Coordinator and Deputy - Base
	     1 - Engineer Floor Manager - Project

	The remaining 3 techs will be CERN based General Labor,  who are experienced in the delicate rigging, logistics and fine 
	mechanical adjustments required by these tasks.
	
	Among the three major installation subtasks it is assumed that 20% of the total resources will be directed towards the 
	installation of the 80 global alignment components, 70% for  the 240 MDT chamber installation and 10% for installation of 
	the 32 CSCs.
	Comments:	For purposes of this WBS it is assumed that the installation of all object types will be optimized between the 
	two chamber technologies (CSC,MDT) and the alignment system components.
