Burns Cooley Dennis, Inc. (BCD) realizes the important role that in-depth and accurate characterization of soil properties plays in the overall success of any project. The firm maintains a fully equipped and staffed soils laboratory for performing strength and compressibility tests, permeability tests, classification tests and other physical property tests.
BCD maintains a well equipped and fully staffed soils laboratory for performing strength and compressibility tests, permeability tests, classification tests and other physical property tests. The BCD soils laboratory includes 1,200 sq ft of laboratory space and 310 sq ft of climatic control sample storage space. The soils laboratory is divided into five separate work areas: (1) an area for consolidation, triaxial, direct shear and permeability testing; (2) an area for Atterberg limits, water contents, -200’s and other routine index tests; (3) an area for unconfined and Q triaxial compression tests; (4) an area where lab technicians perform their paperwork and engineers examine samples for test assignments and to evaluate lab test results; and (5) an area where all sieve and hydrometer tests are performed, including a sound insulated shaker room, and all undisturbed Shelby tubes are extruded.
The BCD laboratory includes six Casagrande lever arm and nine GeoJac loading devices for consolidation testing; three 2,000-lb, one 5,000-lb and one 10,000-lb load frames for compression testing; four hydraulic panels for backpressure saturation and triaxial consolidation; eight flexible wall triaxial chambers; and miscellaneous apparatuses for conducting routine classification and index tests. Automated data collection and reduction are utilized for triaxial compression, unconfined compression, direct shear and consolidation tests. Our laboratory is staffed by 4 technicians having from 10 to 37 years experience.
The types of tests performed in our laboratory include:
– UU triaxial compression tests
– CU triaxial compression tests with pore pressure measurements
– Direct shear tests
– Consolidation and swell tests
– California Bearing Ratio tests
– Unconfined compression tests on soil
– Unconfined compression tests on rock
– Permeability tests
– Soil Suction Tests
– Standard and Modified Proctor compaction tests
– Atterberg limit tests
– Sieve analysis tests
– Hydrometer tests
– Moisture content tests
– Dry density tests
– Shrinkage limit tests
– Specific gravity tests
– Total Organic Content
Our laboratory facilities have been certified and inspected by the Corps of Engineers (USACE), Mississippi Department of Transportation (MDOT), AASHTO, and the Louisiana Department of Environmental Quality. BCD participates in AMRL’s soils and aggregates proficiency program, which is a national testing program that evaluates testing accuracy. Our technicians are currently certified by MDOT, ACI, AASHTO and NICET.
