<br />Lead Geotechnical Engineer, Brandon Shores Units
<br />1 & 2 FGD Retrofit, Constellation Energy Group,
<br />LLC, Curtis Bay, Anne Arundel County, MD.,
<br />07/2006 - Present. The Brandon Shores Units I & 2
<br />FGD Retrofit includes tlue gas ducts, booster fans, tlue
<br />gas desulfurization (FGD) system, chimney, reagent
<br />preparation area, gypsum dewatering area, transformers,
<br />\'arious tanks, limestone storage and gypsum storage
<br />areas, and conveyors for limestone and gypsum. Also
<br />included are waste water treatment, barge unloading, and
<br />cons truction unloading areas.
<br />
<br />Accomplishments:
<br />Re\'ie\ved available subsurface information. Prepared
<br />specification for subsurface investigation by a
<br />subcontractor. Assigned laboratory soil tests, and
<br />re\'iewed draft Geotechnical Data Report. Performed
<br />settlement analysis and determined that major structures
<br />could be supported on shallow foundations. Developed
<br />recommendations for allowable bearing pressure.
<br />
<br />Lead Geotechnical Engineer, Bridgeport Harbor
<br />Station Unit 3 Mercury Control System, PSEG,
<br />Bridgeport, CT, 03/2006 - Present. The ~[ercury
<br />Control System includes a pulse-jet fabric tilter building,
<br />acti\'ated carbon injection silo, tly ash silo, booster fam,
<br />ductwork, and transformers. All major structures will be
<br />supported on augered cast-in-place concrete piles.
<br />
<br />i\ccomplishments:
<br />Revie\ved a\'ailable subsurface information and
<br />recommended locations of additional borings.
<br />Performed calculations to determine seismic site class,
<br />allowable pile load and (for booster fans) dynamic
<br />stiffness of pile foundation. Prepared specification for
<br />piles. Revie\ved specification for earthwork. \'\fitnessed
<br />test pile installation at ash silo. Reviewed results of pile
<br />load tests at PJ FF and ash silo. Visited site during pile
<br />installation at ash silo, and recommended ways to
<br />overcome pile installation problems at that location.
<br />
<br />Lead Geotechnical Engineer, Brunner Island Unit 3
<br />ESP & FGD Projects, Pennsylvania Power and
<br />Light, York Haven, PA, OS/2005 - Present. Project
<br />includes new precipitator sections, chimney, l\vo
<br />absorbers, limestone preparation and gypsum dewatering
<br />facilities, fans, various tanks, ductwork, conveyors, a
<br />limestone unloading facility, and limestone and gypsum
<br />
<br />stockpiles. All major structures will be supported on
<br />augered cast-in-place concrete piles. The limestone and
<br />gypsum stockpile areas are at the location of a former tly
<br />ash disposal basin.
<br />
<br />[\ccomplishments:
<br />Developed specification for subsurface in\'Cstigation by
<br />a subcontractor, assigned laboratory tests on soil and
<br />rock samples, revie\ved draft Geotechnical Data Report,
<br />evaluated soil properties, performed calculations to
<br />determine allowable pile loads and (for booster fans)
<br />dynamic stiffness of pile-supported foundation,
<br />witnessed pile load tests at precipitator location, and
<br />developed geotechnical design criteria. Evaluated
<br />methods for providing lateral support of a deep
<br />exca\'ation in loose, saturated tly ash.
<br />
<br />Lead Geotechnical Engineer, Rochester, New
<br />Hampshire Commercial Development, Mainely
<br />Rochester Pizza, Rochester, NH, 04/2003 -
<br />Present. Two restaurants and a car wash arc proposed
<br />to be constructed at this site. Highlights include:
<br />
<br />The site is a former landfill that is underlain by highly
<br />compressible peat. \,\'ithout foundation treatment or the
<br />use of deep foundations, structures would undergo
<br />unacceptably large total and differential settlements.
<br />
<br />After an initial e\'aluation, a pile foundation \vas
<br />recommended because this would eliminate potential
<br />settlement problems and \vould permit construction to
<br />begin quickly. HO\vewr, the Client considered the cost
<br />of a pile foundation to be excessive, and recjuestecl
<br />additional alternati\'es is studied.
<br />
<br />I t was determined that preloading with 10 ft of fill would
<br />be effective, provided that at least 3 months were
<br />available in the schedule. Settlements would be
<br />monitored to determine when the preload could be
<br />removed. The buildings would then be supported on
<br />mat foundations.
<br />
<br />Two of the building locations were preloaded for
<br />approximately 6.5 months, resulting in approximately 18
<br />inches of settlement at the middle of the preloads. The
<br />preload material is to be shifted to the third building
<br />location shortly.
