SOUTH FLORIDA WATER MANGEMENT DISTRICT GENERAL ENGINEERING SERVICES Accomplishments: De,"cloped initial recommendations for timber piles (size, lcngth and capacity). Performed settlement analyses to estimatc scttlcments with and ,vithout preloading. Prepared recommendations for preloading and for settlement monitoring program. E,"aluated settlement data and determined when the preloads could be rcmo,"cd. Lead Geotechnical Engineer, Brayton Point Flue Gas Desulphurization and Selective Catalytic Conversion Systems, PG&E National Energy Group, Somerset, MA, 07/2002 - Present. The project ,vill add a Selcctivc Catalytic Rcduction (SCR) system to Units I and 3, and a Flue Gas Desulphurization (FGD) systcm to Unit 3. ,:\n Ash RcC(),"ery Process systcm \V.ill be added to process fly ash and to storc it on site in a l6S ft diameter by 107 ft high concrete dome. Project highlights included: Large lateral and uplift loads on the SCR foundations. Thesc loads wcre resistcd by high-capacity (mostly S()()- kip), post-tcnsioned rock anchors installed to depths of up to 86 ft. The dome for fly ash storage is underlain by soft clay that would cause the dome to settle excessi,'ek. Recommended that the clay be excavated and replaccd \vith compacted granular till. Accomplishments: Prepared scope of work for subsurfacc investigation at the locations of the propos cd systems. Prepared reports presenting results of borings and geotechnical laboratory tests, and preliminary recommendations for foundations and earthwork. Prepared specitlcation for SOO-kip rock anchors, which were successfully installed and tested. Preparcd eartlnvork specitlcation for the ARP system. Lead Geotechnical Engineer, Medway Power Station, Containment Dike for No.2 Fuel Oil Storage Tanks, Excelon Power, Medway, MA, 06/2006 - 08/2008. During an extended period of rainfall, water ponded to a depth of a couple of feet within the containment dikc for two No.2 fuel oil storage tanks. Seepage was noted along the base of part SHAW ENVIRONMENTAL, INC. 06C122006T of the exterior slope of the dike. A zone of dark soil indicating a wet condition was obser;ed to extend laterally beyond the zone of seepage. Client recluested an assessment of the dike condition. Accomplishments: Visited the site to ,"iew the condition of the dike where the seepage had been noted, and concluded that the seepage posed no danger to the dike. Subsequently, examined the entire dike and identified locations where burrows had to be tilled and additional till placed to re- establish the design cross section of the dike. Lead Geotechnical Engineer, Marshall Steam Station FGD Retrofit, Duke Energy, Terrell, NC, 02/2004 - 02/2005. Design and construction of a Flue Gas Desulphurization System for Units 1--1-. Project highligh ts include: Residual soils of moderate compressibility and \"ariable thickncss, undcrlain by partially weathcred rock that is csscntially incomprcssiblc. The thickness of residual soil varied from approximately 2 ft to 30 ft bcneath the location of thc U nit -I- Absorber and thc southcrn part of the i\bsorber Building. This would causc unacceptable differcntial settlcmcnt of thcse structures. This problem was addressed by m"er-exca,"ating (to depths of up to IS ft) the thick sections of residual soil at thcsc locations, and backftlling with compacted crushed stone. ,\ccomplishments: Prepared sketches showing where over-excavation and back tilling with compacted crushed stone was required. Performed settlement analysis of Limestone Preparation Building to demonstrate that over-excavation was not recJuired at that location. Provided input to a specitlcation for drilled shaft foundations to support ductwork, and to a specitlcation for a soil-nail wall for the limestonc unloading facility.
