The Fort Frances School
TBT Engineering’s Role
Tasks included preliminary geotechnical investigations, pre load inspections, laboratory materials testing, field services, mechanical, electrical design and an extensive geotechnical drilling program.
Tasks included geophysical investigations, geotechnical sampling. Geotechnical engineering recommendations were then developed and included topics such as ultimate bearing pressures, depth to founding strata, anticipated constructability issues, soil backfill requirements, potential for reuse of excavated soils, and preload design parameters.
All necessary drilling was completed using our in-house drilling department. Hollow stem augers facilitated soil sampling and down hole testing. Diamond core drilling was used to sample bedrock.
Intervisable Control Establishment Surveys
Control Surveys were completed for proposed new school. Trimble Series 3 R8 RTK Survey Grade GPS Systems were used, control points were established and related information, along with detailed site plans, were provided.
Materials Testing – Laboratory
An extensive laboratory testing program was undertaken and included testing for moisture content, grain size analyses, and plasticity. Other tests such as compression or point load testing where used for concrete and bedrock.
TBT Engineering performed hundreds of field compaction tests and also completed all concrete quality testing. Subgrade inspections were completed to verify the suitability of materials for foundation bearing.
