Burns Cooley Dennis Inc

Specialized analysis and engineering for soils and foundations, supporting civil and infrastructure projects through comprehensive field exploration, testing, and monitoring.

• Subsurface Investigation

  Performs subsurface exploration using truck-mounted and buggy-mounted rotary drill rigs, specializing in land and barge drilling, undisturbed Shelby tube and split-spoon sampling.

• Field Instrumentation

  Installs and monitors slope inclinometers, groundwater monitoring wells, open standpipe and vibrating wire piezometers, downhole extensometers, and settlement plates.

• Vibration Monitoring During Construction

  Provides vibration monitoring using seismographs to help limit the exposure of surrounding facilities to construction-related vibrations.

• Field Measurement of Soil Resistivity

  Measures soil resistivity using ground resistance testers and the Wenner Four Electrode Method for corrosion control and grounding system design.

• Pile Driving Analyzer (PDA) Services

  Dynamic load testing and capacity evaluations of driven piles using PDA systems, WEAP analysis, and CAPWAP computer modeling.

• Pile Integrity Testing (PIT)

  Evaluates drilled shafts and auger cast-in-place piling for defects and identifies unknown deep foundation bearing depths.

• SPT Hammer Calibrations

  Calibrates SPT hammers in accordance with ASTM procedures to improve test reliability and compensate for efficiency variations.

• Geotechnical Laboratory Testing

  Maintains a fully equipped soils laboratory for consolidation, triaxial shear, permeability, compaction, and classification tests.

Comprehensive testing and evaluation of soils, earthwork, concrete, and asphalt materials within AASHTO-accredited laboratory facilities.

• Earthwork Laboratory and Field Testing

  Evaluates embankment and subgrade soils using nuclear density gauges, sand cone measurements, California Bearing Ratio (CBR), and resilient modulus tests.

• Asphalt Materials Laboratory

  Rheological characterization of asphalt binders, Superpave performance grading, and hot mix asphalt mixture designs including Marshall and Superpave methods.

• Concrete Materials Laboratory

  Cures and tests rigid pavement and structural concrete materials, offering compressive, splitting tensile, flexural strength, and concrete unit weight tests.

• Field Materials Evaluations

  Utilizes portable coring rigs, generators, nuclear density gauges, and dynamic cone penetrometers to conduct in-situ materials testing.

Specialized evaluation, structural design, performance monitoring, and forensic analysis for rigid, flexible, and composite pavement systems.

• Pavement Structural Design

  Develops designs for unsurfaced roads, streets, highways, airfields, ports, and industrial facilities using AASHTO, FAA, and mechanistic-empirical methods.

• Pavement Construction Technical Assistance

  Provides technical assistance on pavement construction projects involving hot mix asphalt, Portland cement concrete, and chemical stabilization.

• Pavement Condition Surveys

  Conducts condition surveys for roads, parking lots, and airfields, utilizing pavement management software to develop maintenance strategies.

• Pavement Maintenance and Repair

  Formulates engineered recommendations for the maintenance, repair, and rehabilitation of rigid and flexible pavement structures.

• Forensic Pavement Analysis

  Conducts in-depth forensic investigations of rigid and flexible pavements using dynamic cone penetrometers and specialized concrete/flexible pavement coring equipment.

• Resin Modified Pavement Construction

  Designs and implements resin modified pavements utilizing hot mix asphalt and cement slurry grout for high-stability applications like tank trails.

• Specialty Asphalt Mixture Design

  Establishes design and construction guidelines for specialty hot mix asphalt mixtures, including stone matrix asphalt and open-graded friction courses.
