• Forensic studies of causes for subsidence or settlement of land or structures; primarily for insurance investigations
• Sinkhole risk studies using GIS techniques
• Studies of raveling conditions in roadway subgrade related to water main pipe breaks
• Studies of raveling conditions for reconditioning of older storm water pipes or historical box culverts
• Studies of void space below concrete slabs and dam/levee soil cement
• Identification of clandestine or unmarked grave sites
• Depth to limestone mapping for retention ponds and pipelines
• Utility and pipe mapping for water treatment plant refurbishment

• Confirmation testing for underground storage tanks (UST’s)
• Holistic mineral resource evaluations using GIS

Robert M. Baker, P.G. is the founder, managing member, and principal consultant for RMBAKER LLC, and is a licensed professional geologist in Florida .  Mr. Baker received a Bachelor of Science degree in geology from Northeastern University in 1992, and a Master of Science degree in geology from the University of Florida in 1997.  Mr. Baker’s graduate research focused on processes of karstification in Florida 's deeply buried limestones, with emphasis on the use of natural isotopes as indicators of past water-rock geochemical interactions.

Since 1995, Mr. Baker has specialized in the characterization of Florida 's varied geological settings, with several years of international experience with coastal geology studies in Brazil and Ecuador .  He is an authority in the use of non-invasive surface geophysical methods such as GPR and ERI, particularly in Florida ’s heavily karstified geologic settings. 

Mr. Baker has expertise in the evaluation of potential mineral resources as part of a comprehensive regional study.  He has performed extensive studies to evaluate complex mineralogical and geochemical datasets for the purpose of assessing resource potential and calculating mineral reserves.  He has experience with known mineral deposits and reconnaissance exploration programs throughout the U.S. , Brazil , Ecuador , and Australia .

Mr. Baker has considerable experience with the sensitivities associated with insurance investigations of sinkholes in Florida .  He is an expert in the techniques and methodologies for the identification of sinkhole related conditions, particularly as they relate to ground subsidence studies for residential or commercial properties.

Mr. Baker co-authored several abstracts regarding the origin of deeply buried karst in south Florida .  Current research interests include the use of induced potential geophysical techniques for mapping titanium mineral deposits, geophysical mapping of subsurface karst for water management studies, and development of techniques for integrating GPS and topographic data into geophysical field exploration methods.  Mr. Baker is a member of the Geological Society of America (GSA), the Society of Economic Geologists (SEG), the Society of Exploration Geophysicists (SEG), and the Florida Association of Professional Geologists (FAPG) which is the Florida Section of the American Institute of Professional Geologists (AIPG).

Mr. Baker was employed at Rimkus Consulting Group, Inc. from July 2001 to January 2004, where he was project manager for a variety of geotechnical investigations designed to evaluate problematic soils and sinkholes.  He performed geotechnical site assessments using a combination of surface geophysics, shallow auger borings, and deep standard penetration and cone penetration test borings.  Ground penetrating radar surveys were performed for the purpose of identifying sinkholes, localized stratigraphy, underground storage tanks, utilities, buried debris, excavated areas, hydrocarbon plumes, and erosional and depositional patterns in lake sediments.

Mr. Baker was contracted to Dupont from May 1998 to July 2001.  Mr. Baker was the principal investigator of a one million acre macrotidal sedimentary system in northeastern Brazil , searching for economic deposits of heavy minerals rich in titanium.  This involved the coordination of leveraged resources, Brazilian federal agencies and international law firms.  He also performed field work and/or evaluated heavy mineral placer assays and reserves in Florida , Australia , Ecuador , Brazil and the western United States .  As part of his mineral exploration work he evaluated large complex datasets derived from rock sample analysis incorporating particle size analysis, XRF, XRD, SEM, EDX, electron microprobe, optical microscopy, gravity separation, HT separation, magnetic separation, and photomicroscopy.  In addition to his mineral exploration duties, Mr. Baker provided team leadership for ore assay analysis and sedimentological modeling of known but undeveloped mining resources in Florida .  He established quantitative methods for placer deposit petrographic and geochemical modeling using high-end 3D modeling software and geostatistics.

Mr. Baker was employed by Geohazards, Inc. from June 1995 to May 1998.  As Director of Field Operations he developed investigation strategies and field procedures for geophysical studies, submitted contract bids, and supervised field crews.  The geophysical techniques included electrical resistivity and ground penetrating radar.  Project scopes ranged from aquifer/aquiclude delineation, stratigraphy, large municipal landfill site-evaluations, reconnaissance for foundation designs and grouting programs, identification of buried debris, and sinkhole-related ground settlement evaluations.
