  • Services Provided

    line
    MCG's services fall into three primary categories - Enviromental Consulting Services, Geotechnical Engineering Services, and Geotechnical Laboratory Services. Environmental Consulting Services include assessment and coordination of remediation of contaminated sites. Geotechnical Engineering Services include evaluation, analysis, and design of slopes, foundations, earthen structures as well as evaluation of the interaction between structures and soil. Geotechnical Laboratory Services includes soil classification, soil index properties, permeability, soil load-deformation tests and evaluation of Constrained Modulus (Ms) for crushed rock samples.

Krejci Dump Site 8_13_2013MCG Geotechnical Engineering can assure compliance with environmental laws and regulations, design and implement site characterizations, perform human health and ecological risk analyses associated with physical and chemical hazards, manage programs through and in all steps of the CERCLA process, and prepare reports and legal documents. MCG specializes in incremental sampling, multi increment sampling, risk-based composite sampling plan design, implementation and sample processing. Our President, Dr. Mark Gemperline, developed risk-based composite sampling theory for application at environmental sites in 1991 and has since successfully implemented the methodology to characterize many CERCLA and other hazardous waste sites. Specialties include contaminant transport modeling and the characterization and remediation of mine sites and municipal and industrial waste disposal sites. MCG also performs environmental site assessments and underground storage tank investigations.

MCG also provides archeological structural and groundwater assessments and makes recommendations for preservation.

Krejci Comparction CurvesIMG_0421MCG’s geotechnical engineering  services include forensic analyses, slope stability analysis, foundation design, retaining wall design, all facets of soil structure interaction evaluation, embankment evaluation and design, and laboratory testing. Our staff has decades if experience in research and applied geotechnical engineering,  geology and other civil engineering fields. Specialties include large scale testing of soils containing gravel. Testing in this regard includes one dimensional compression and permeability testing.  MCG also specializes in the design and testing of flowable fill (a.k.a., controlled low strength material, CLSM).  MCG’s in-house testing laboratory performs all basic geotechnical laboratory tests in accordance with ASTM standards. MCG both develops and applies computer applications to solve complex civil engineering problems. MCG has both unique capability and experience evaluating stockpile stability and angle of repose; experimentally determining constrained modulus and permeability (hydraulic conductivity) for gravel and soils containing gravel; and experimentally determining representative Poison’s ratio and the Young Modulus (elastic modulus) for gravels. Finally, MCG provides inspector training and short courses on the subjects of soil classification and properties.w sketch61Who We Arepic3Picture3Image16990750-R1-014-5APOOP-Layout4
