The MRCE team of geotechnical engineering professionals possess an experienced understanding of the behavior of soil under a range of structural demands, and the definition of soil material properties for design.

  • Subsurface Conditions
    A thorough assessment of subsurface conditions and the engineering properties of soil is fundamental to selection and design of cost efficient and constructible foundation systems. MRCE geotechnical engineers are experienced in traditional investigation sampling methods and soil classification, and state of the art tools for in-situ testing of soil properties to support subsurface investigations and construction projects. MRCE engineers are experienced at producing geotechnical data reports and interpreting geotechnical conditions to guide foundation design and construction.
  • Soil and Rock Mechanics Laboratory

    MRCE maintains a state of the art soil mechanics laboratory in our New York office which is devoted to MRCE client projects and designs or evaluation assignments. NICET certified technicians perform tests following applicable ASTM standards, expanded as needed to meet project requirements. The MRCE lab is accredited by the American Association of State Highway and Transportation Officials (AASHTO).

  • Advanced Geotechnical Analysis
    Geotechnical analysis using advanced numerical methods such as soil-structure interaction finite element modeling, and groundwater modeling can often better simulate complex geotechnical problems, define earth and water loads, and result in more economical designs compared to conventional analysis. MRCE analysts are experienced modelers with a real-world project performance history. Advanced analytical tools for state-of-the-art soil-structure interaction analyses are used to estimate the complex behavior of soils and the response of earth retention structures and adjacent structures, allowing our Clients to develop appropriate designs and manage construction risk in urban environments. Our engineers are familiar with two dimensional (2-D) and three dimensional (3-D) transient and steady state groundwater modeling techniques for estimating groundwater behavior, and designing effective groundwater control systems in challenging ground conditions.
  • Rock Mechanics
    Careful application of rock mechanics principles is of particular import in the urban environment, where rock excavations are typically adjacent to existing structures. Recognizing that rock instability can occur suddenly and without warning, MRCE engineers utilize time-tested methods of rock mechanics data collection and analysis to identify and clearly communicate potential trouble spots before the excavation proceeds, enabling our clients to estimate the cost and schedule impact of anticipated rock reinforcement measures. Our engineers are experienced in rock mass characterization to assist our clients in developing appropriate and cost effective reinforcement and rockfall protection systems for slopes and tunnels. MRCE utilizes Distinct Element Modeling (DEM) software to estimate stress and deformation around underground openings in jointed rock, where the behavior of the discontinuous mass may not be adequately predicted by continuum models.
  • Seismic Design
    Site-specific studies for optimizing seismic loads are essential to efficient structural systems. MRCE has offered site-specific studies as a core capability of our geo-seismic practice for more than two decades. Studies include in-situ geophysical testing, laboratory resonance testing of rock core, and use of Bender elements for laboratory testing of soils under triaxial confinement. MRCE performs probabilistic and deterministic seismic hazard studies for critical facilities and infrastructure projects. MRCE has performed international projects where regional hazards are not mapped. MRCE specialists have supported seismic code revisions and development of design guidelines including ASCE7-16, EC-8, NYC Criteria for Bridges, and the NYC Seismic Code.
  • Groundwater Control
    Proper control of groundwater is fundamental to safe and efficient construction of projects below the water table. MRCE is recognized as an expert in construction dewatering. MRCE Partner Walter Kaeck, PE has primary contributions to the authoritative text “Construction Dewatering and Groundwater Control: New Methods and Applications.” MRCE engineers design, execute and interpret field pumping tests to measure hydraulic properties of water bearing strata and aquifers. Our engineers also possess in-depth knowledge of groundwater control alternatives, with a tool kit ready to tackle any ground condition and project demand including deep and shallow wells, wellpoints, ejectors, horizontal drains, slurry trench barriers and sealed sheet pile cutoff walls, particulate and chemical grouting, and water cutoff methods. MRCE engineers focused on groundwater problem definition, design, and problem solving are available as a resource to Clients.
