Site Preparation Purpose
Site Preparation was included as an earlyprocurement (authorized pre-CD-3) to: Provide an activity that reduced schedule risk to the
Ring Building by:
Reducing potential for unknown utilities or site conditionsdelaying construction start
Reduce GC schedule risk during early construction
Be mobilized to correct any deficiencies left over from
previous activity at the site (leftover facilities orenvironmental liabilities)
It provided a number of other benefits as well

Site Prep Status
All base scope work completed -2/17/09 running underbudget
Some minor punchlist / closeout items remain Added some items to scope
Enlarged recharge basin & stockpiled structural fill due to
seasonal environmental permit constraint Added maintenance of erosion control until Ring Bldg
Contractor mobilizes
Added clean-up of miscellaneous debris
No evidence of environmental liabilities Ready for Ring building GC

Site Preparation Lessons Learned
Summary Site access control requirements
NSLS-II CM Staff increased knowledge of BNLsystems, procedures, personnel and points of contact
Understanding of requirements for shutdowns,notifications, permits and utility tie-ins
Utility mark-outs and surveys will assist Ring Buildingutility installation
Improved coordination of field inspectors and safetyengineers in oversight of contractor performance

Site Preparation Lessons Learned
Better understanding of site access control requirements
Repeated unauthorized incursions of area by Lab personnel- Despite Signs, Roadblocks and Web & Email Postings
Additional time & effort spent:- Chasing Unauthorized Personnel from Area,
- Maintaining Signs & Barricades
On-site fauna destroyed construction fencing in path to food,
habitats Need for well managed permanent fence instead of temporary
construction fence

Path Forward
Employ Lessons Learned on Site Preparation
Start Permitting Process Early,
Recommend Site Access Control Measures to Ring BuildingContractor
Continue to Coordinate with BNL Site Operations to precludedelays,
Keep current with BNL Procedures / Systems
Partner with Ring Building GC to expedite mobilizationand communication, to facilitate efficient resolution ofissues as they will inevitably arise.
