ICC SOILS CERTIFICATION EXAM 2025
QUESTIONS AND CORRECT ANSWERS |
A+ GRADE STUDY RESOURCE
Types of slope stability Correct Answer Drainage
slope reduction or flattening
structural solutions
chemical stabilization
what would stabilize a slope that has been effected by
seepage water? how does this improve slope stability?
Correct Answer Sub- drainage, decreases the saturation
of the slope
when a slope begins at vertical cut what is done to
stabilize the slope? Correct Answer removing the upper
portions or head of the slope or landslide is the frequently
employed technic for reducing the driving forces that
cause the failure to occur
what are red lights on a site? Correct Answer low bearing
capacity
settlement
existing uncontrolled fill
slope stability
dangerous seismic conditions
frost heave
constructabilty- piers or piles
proposed significate cut or fill
,groundwater problems
foundation red lights Correct Answer design not in
accordance with geotechnical recommendations
foundation location differs from site investigation location
foundation plans not adequate or complete
low bearing capacity not recognized in footing design
compressible or expansive soil on site not anticipated in
design
water seepage not anticipated in design
seismic conditions not documented properly in design or
calculations
provisions dealing with frost heave not included
retaining structures or basement walls without adequate
drainage
underfloor crawl space not vented or drained
when should concrete be placed? and what raises red
flags in the design? Correct Answer within 90 minutes of
adding water at the concrete plant
, excessive water should not be added at the site, no more
the 5 gallons per truck
if air temperatures are higher then 90 degrees and the
humidity is less then 25 percent , concrete may suffer
drying shrinkage cracking
concrete should not be placed if air temperatures are 40
degrees and falling unless special cold weather measures
are placed
foundation grades and drainage must dos Correct Answer
surface water must be directed away from the foundation
area and not be permitted to stand within or adjacent to
the work
foundations must have and adequate concrete reveal of 4
to 8 inches before the top of the soil is encountered
areas around the foundation must slope away to a swale
or drainage pipe system that will drain adequately off site
slopes should have approximately 6- inch fall within 10
feet from building on all sides for all buildings, including
residence
site preparation must dos Correct Answer site must be
cleared of top soil, grass, bushes, trees, old structures, or
old pavement
