Conventional Facilities Current Working EstimateMay 8, 2008

2 BROOKHAVEN SCIENCE ASSOCIATES

Current Working Estimate• Current Working Estimate Based on the Following:

– Results of T-II 30% estimate by VJ Assoc reconciled with T-II 30% estimate by Liro/Gilbane

- S. Sawch led estimate reconciliation process (A/E, CM, PE)– Modified by A/E or BNL estimate of known changes to 30% design

by approved or pending change orders or VE items– Includes estimates and allowances for:

- All base scope required for CD-2- Change in CM approach to BNL CM team- Added A/E cost for design changes- Modifications to facility design likely to be reflected in 50%

A/E design pkg- Transfer of DI-PCW scope from ASD to CFD- Escalation to at-year $ to midpoint of construction @5%

Path Forward

• Continued effort underway to reduce cost where possible• Working with siding and roofing vendors to firm up unit cost

and arrive at lowest system cost• Working with concrete vendors to verify unit cost differences

for slab vs wall vs roof pours• Electrical substation VE items recently identified• A/E Design to Cost leverage & Formal VE Planned

• Assessment of overall CF cost risk vs project risk/contingency underway
