GEM Engineering

Subsurface investigations, laboratory testing, soil calculations, groundwater/dewatering analysis, retaining-wall support, pavement design, and borrow-source evaluations for residential, commercial, and industrial projects.

• Geotechnical Site Investigations

  Subsurface investigations, laboratory tests and respective soil calculations to determine soil properties for geotechnical reports.

• Distress Investigations

  Includes foundation studies and soil failure under existing structures, including recommendations to correct the problems.

• Dewatering Systems

  French drains, foundation drains, well points, seep spring analysis, seasonal and year-round groundwater analysis.

• Retaining Walls

  Engineered retaining walls including concrete, MSE, boulder faced and block faced, tie-back walls and reinforced slopes. Walls are designed on soil characteristics and properties.

• Pavement Designs

  Pavement section design based on soil conditions and designed traffic index to provide a durable, long lasting roadway.

• Borrow Source Evaluations

  Samples obtained from proposed borrow sources are analyzed in the onsite lab to determine characteristics to meet state and/or local government specified requirements and for use as structural fill.

Environmental site assessment, groundwater monitoring, well sampling, compliance observations, groundwater studies, percolation testing, septic design, and lagoon analysis for real estate, geotechnical, and environmental projects.

• Environmental Site Assessment

  ASTM specified Environmental Site Assessments for residential, commercial and industrial real estate transactions.

• Monitoring Wells

  Establish groundwater conditions for environmental and geotechnical projects.

• Well Sampling

  Obtain water samples from monitoring wells for chemical analysis.

• Regulations Compliance

  Reports, observations, inspections to meet local, state and federal mandated requirements for geotechnical and environmental projects.

• Groundwater Studies

  Analysis of groundwater flow, gradient and quality to assess potential impacts on geotechnical and environmental projects.

• Percolation Tests

  Analysis of percolation rates in soil for the purpose of designing septic systems and storm water drainage.

• Septic Design

  Engineered design based on percolation rate for individual residential or commercial waste water treatment systems.

• Sewage Lagoons

  Analysis and design of large lagoons for commercial, agricultural and industrial waste water treatment systems.

Field and laboratory testing of concrete, soils, and asphalt to verify engineering properties and specification compliance for construction projects.

• Concrete

  Field and laboratory analysis of freshly mixed concrete to determine slump, air entrainment and compressive strength characteristics in accordance with American Concrete Institute (ACI) specifications.

• Soils

  Field and laboratory analysis of soils to determine engineering properties for use as structural fill to meet required specifications.

• Asphalt

  Field and laboratory analysis of Hot Mix Asphalt (HMA) to determine engineering properties including oil content, gradation of material, lay down temperature and density to meet required specification.

Required by the International Building Code (IBC) for most commercial buildings, especially in high seismic areas, to verify that critical structural aspects of the drawings are met and that construction is completed in accordance with the structural mandates prescribed in the building code.

• Reinforced Steel
• Masonry
• Bolting

Structural review, design, evaluation, and repair/rehabilitation support for residential and commercial structures, from permit reviews to full structural calculations and drawings.

• Structural Review

  Review of commercial and residential plans requiring an engineering stamp before issuing a building permit, performing a thorough structural review of plans for any project type.

• Structural Design

  Provides structural calculations and creation of structural drawings, ranging from a simple foundation design on a small residential project to a full structural design and detailing of a large commercial structure.

• Structural Evaluation

  Preliminary to exhaustive structural evaluation of a structure to identify and quantify existing and potential structural concerns, whether for a property purchase or in response to visible signs of damage.

• Repair and Rehabilitation Design

  Practical and cost effective solutions to structural problems and deficiencies for owners and contractors.
