  1. ILC Mechanical & Electrical Review Conventional MECHANICAL System Design Summary Emil Huedem, FNAL Lee Hammond, FNAL Parsons Mechanical Team (Tim Sheehan, Jerome Burke, Michael Painter) March 21, 2012

  2. INTRODUCTION • Process cooling water, ventilations, and sump system • Cryogenic system is not included but only it’s final heat rejection (cooling towers) • Sizing (&costing) for full power first (adjustment to lower power-baseline will be done later) • Criteria/Load tables used was before July 2011. Many changes since • Parsons did the concept & costing for both KCS-ML and DRFS-ML. Only KCS is considered in this review • Costed each system-bottoms up, per shaft, per system (in RDR scaled from shaft 7) • Some items just have cost ($/m fire suppression, $ target ventilation, $laser room HVAC, $compressed air from RDR)

  3. WBS • Follows the RDR WBS system • Specific wbs only 1.7.3 AIR TREATMENT (HVAC) 1.7.4 PIPED UTILITIES 1.7.5 PROCESS COOLING WATER

  5. CRITERIA / TECHNICAL LOADS In Central Region ML loads comes from RF system & racks For KCS, more than 60% of ML loads are in the surface Some key criteria/input Various area system heat load tables (except e-) Various delta T per users Machine design to run all year or anytime in a year DR & BDS has tight space (air) stability Lcw/process water supply stability not critical 150 gpm per mile inflow for groundwater RECENT CHANGES ARE NOT INCLUDED HERE

  23. ADJUSTMENT TO FINAL NUMBERS PARSONS’s MECH COST EXCEL PARSONS’s ELEC COST EXCEL • Separate cost by Area systems • Add missing wbs • Adjust IR water plant cost • Adjust Ventilation cost • Add laser rooms • Add Fire suppression • etc CIVILCOST EXCEL • Scale per new load/criteria • Adjust cost to low power ADJUSTED MECH COST EXCEL ADJUSTED ELEC COST EXCEL OVERALL CFS COST EXCEL (AMERICAs) LINK or INPUT ? Add EDMS references Add other mandatory input Risk Basis (high & low %) GERRY DUGAN’s EXCEL FILE ( CEM)

  24. 28F dt • Stacking of loads in surface RF considered but not used • Not much first cost savings, (10” to 8” pipe mains) vs effect of high space temperature

  25. Chiller vs w/out chiller on DR

  26. POST RDR • About 50+ list from V.E. in Nov 2007, List from value engineering sessions in Nov 2007. Some appear to have real good cost reduction potentials. • Project focus on “first-cost” reduction • Talks located in http://ilcagenda.linearcollider.org/conferenceDisplay.py?confId=2328 • Description of each list, but no detailed evaluation • Specific items selected by project to be evaluated in 2008 • Elimination of centralized chilled in ML • Higher RF water delta T • Warmer tunnel temperature during operation and local cooling during maintenance • Other pipe materials • discussions during this effort effort • Centralized LCW vsprocesswtr/skid • Tunnel booster pump footprint=2/rf • (stacking of loads) Surface RF High delta T 28 Fdtvs 15F = not much cost savng • Surface RF ventilate or part of rack • DR chilled water or not
