Survey Tech
This surveying instrument combines electronic distance measurement with angle measurement capabilities.
What is a total station?
Lines connecting points of equal elevation on a map are called these.
What are contour lines?
What is gravel?
Before finalizing foundation sizes, a structural engineer should verify that calculated soil pressures do not exceed this recommended geotechnical value.
What is the allowable soil bearing pressure?
This test measures the resistance of hardened concrete cylinders to crushing loads.
What is the concrete compressive strength test?
This satellite-based positioning system has largely replaced conventional traverse methods for many large surveys.
GPS
Surveyors often establish these permanent reference points of known elevation.
What are benchmarks?
What is the name for non-native material on a geotecnical report?
What is fill?
This foundation type consists of a large reinforced concrete slab supporting multiple columns and walls over poor soil conditions.
What is a mat foundation
Fresh concrete consistency is evaluated using this common field test.
What is the slump test?
The acronym UAV stands for this.
What is Unmanned Aerial Vehicle?
What does a topographic survey does not contain this.
What is a legal description of the property lines or parcel.
This coarse-grained soil has particle sizes between 0.075 mm and 4.75 mm and is commonly used for drainage applications.
What is sand?
A style of foundation with a thin concrete slab surrounded by a perimeter footing system.
What is a slab on grade foundation?
This test is commonly used to determine in-place soil density and moisture content.
What is the nuclear density test?
Laser scanning technology used to create highly detailed terrain models is known by this acronym.
What is LiDAR?
Elevation and coordinates are referenced back to these.
What is a coordinate system and a datum.
This soil type exhibits high plasticity, low permeability, and significant volume changes with moisture fluctuations.
What is clay?
A geotechnical report often recommends this percentage of Standard Proctor maximum dry density as a minimum compaction requirement for structural fill.
What is 95%
For safety reasons this method should not be used for pipe testing.
What is compressed air testing?
The total station replaced what two traditional surveying instruments?
What are the theodolite and measuring tape.
Surveyors set these so that other can come back in the future for construction staking or as-builts.
What are control points?
This fine-grained soil has particle sizes between those of sand and clay and exhibits low plasticity.
What is silt?
A type of deep foundation consisting of drilled holes filled with compacted aggregate.
One of the most common forms of testing and quality control is this document.
What is a daily report or what is a daily field report?
