1. Overview of the Schedule and Budget for the ARCS Instrument Doug Abernathy ARCS Hardware Project Manager ARCS Construction Project Review DOE Germantown Aug. 9, 2004 SNS Instrument SystemsOak Ridge

2. SNS Instrument SystemsOak Ridge ARCS Baseline from March 2002 Review Original WBS broken down according to components Optimistic schedule

3. SNS Instrument SystemsOak Ridge ARCS Rebaselining effort June-July 2004 Factors contributing to desire to re-examine ARCS cost and schedule: Shift of project from Argonne to Oak Ridge – D. Abernathy June 2003 – Engineering change (R. Williams ANL to K. Shaw ORNL) April/May 2004 Prototyping and early neutronic calculations undertaken after the first project review coming to fruition Funding for SEQUOIA Desire to utilize SNS project controls, cost tracking and integration into installation planning activities

4. SNS Instrument SystemsOak Ridge New WBS Uses model based on SEQUOIA work – Major elements are design, procurement and installation/testing – Costs evaluated using a detailed spreadsheet for each component, incorporating latest information on SNS instrument experiences Data entered in SNS Primavera project control system – Allows for better and more consistent reporting of instrument progress – SNS resources (ORS&T3, ORAPP, …) used for cost basis – there will be some differences due to different Caltech burdens, e.g. no overhead on procurements – MS Project used as an intermediate planning tool until online Primavera available

8. SNS Instrument SystemsOak Ridge Risks and risk management Prototyping and other efforts have reduced risk – Detectors  Signed agreement to give ARCS 3 He from SNS  Prototype module with electronics – Vessel internal shielding  Better knowledge of pumping requirements – Overall shielding and instrument placement  ARCS and SEQUOIA combined design Major items left – Vacuum vessel (cost and schedule) – Neutron guide (schedule) – Shielding (cost)
