Site Preparation Lessons Learned

Michael P. Bromfield, Construction EngineerConvention Facilities Advisory Committee Review

March 10 –11, 2009



• Outline• Site Preparation Purpose• Existing Site• Prior BNL Work• Site Preparation Scope• Lessons Learned• Path Forward


Site Preparation Purpose

• Site Preparation was included as an early procurement (authorized pre-CD-3) to:• Provide an activity that reduced schedule risk to the

Ring Building by:– Reducing potential for unknown utilities or site conditions

delaying 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 or environmental liabilities)

• It provided a number of other benefits as well


Site Preparation - Existing Site

Bldg 100 Demolished

Bldg 87 Demolished

Bldg 210 Demolished

Bldg 481 Demolished

Bldg 211 Demolished

Ring Bldg Footprint

Construction Area Perimeter

Existing Buildings to be removed prior to construction

Bldg 209 Demolished


Prior Work by BNL

• On-going BNL program removed excess facilities/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 and

related 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 under budget

• 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 BNL

systems, 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 Building

utility installation– Improved coordination of field inspectors and safety

engineers 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, personnel

and points of contact



• Lessons Learned–Understanding of requirements for shutdowns,

notifications, permits and utility tie-ins

• Determine Timeframe required for coordination with BNL Depts.

• Requirements for off-hour work due to maintenance of operations, personnel availability.



• Lessons Learned– Utility mark-outs and surveys will assist Ring Building Utility

installation:

• Facilitated planning for temporary utilities, as well as familiarity with 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 incorporate

experiences• 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 Building

Contractor• Continue to Coordinate with BNL Site Operations to preclude

delays,• Keep current with BNL Procedures / Systems

• Partner with Ring Building GC to expedite mobilization and communication, to facilitate efficient resolution of issues as they will inevitably arise.
