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

Prior Work by BNL

On-going BNL program removed excessfacilities/structures Relocated Warehouse Facilities

Demolished Existing Facilities and Slabs/Foundations

Prepared Recycling Area and recycled concrete foundations

Remove Rail Road tracks and ties

Performed clean up and removal of oil-water separators andrelated sanitary piping

Site Preparation Scope

Site Preparation Scope/Construction Packages Clear and Grub Trees

Abandon Existing Site Utilities/Relocate Utilities

Abandon Monitoring Wells/Relocate Wells

Verify no environmental liabilities

Provide Utilities for Construction (power and communication)

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

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




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




NSLS-II CM Team new to BNL Different Culture

Outside world experience

Site Preparation work facilitated: Knowledge / Understanding of BNL/DOE expectations and

requirements

Enhanced familiarity with BNL systems, procedures, personneland points of contact




Lessons Learned

Understanding of requirements for shutdowns,notifications, permits and utility tie-ins

Determine Timeframe required for coordination with BNLDepts.

Requirements for off-hour work due to maintenance ofoperations, personnel availability.




Lessons Learned

Utility mark-outs and surveys will assist Ring Building Utilityinstallation:

Facilitated planning for temporary utilities, as well as familiaritywith existing and surrounding site utilities, infrastructure;

Exposed unmarked structures, utilities, and identified known-unknown utilities.




Lessons Learned Improved coordination of field inspectors and safety engineers in

oversight of contractor performance:

Good Planning & Project Oversight by CF & ESH Teams, Collaborative Approach With Contractors Mitigated Weather

Impacts & Potential Impacts due to Scope Changes,

No Impact to Vehicular & Pedestrian Traffic.




Lessons Learned and experience brought From Outside Staff:

New Technologies, Systems for Administering, managing

projects; Implementation of Primavera Contract Manager,

Slight Modification of BNL Procedures to incorporateexperiences

Experience with CM scheduling and estimating methods Experience with claims prevention and mitigation



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.
