, CM 2112 TEST 1 - QUESTIONS AND ANSWERS WITH COMPLETE SOLUTIONS.
A mass diagram is a cumulative running total of the surplus or deficient material quantities along the
project profile. (T/F) - (answer)True
All piles depend on either the friction between the surface of the pile and the soil, or the load
transmission to the soil through the pile's lower tip. (T/F) - (answer)False
If timber piles remain constantly in contact with water (wholly below the water table) they will
deteriorate after a short period of time. (T/F) - (answer)False
Steel pipe piles are least efficient as friction piles as they have substantial surface area that interacts
with the surrounding soil to provide significant frictional load resistance. (T/F) - (answer)False
(Earthwork Planning) A Type 1 differing site condition exists when actual conditions differ materially
from those "indicated in the contract". (T/F) - (answer)True
Which statement is True about "Type 1 and Type 2 differing site condition" clauses?
(a.) They eliminate the contractor's responsibility for performing a thorough examination of project
conditions.
(b.)They provide the contractor some protection from geotechnical risk and eliminate the contractor's
responsibility for performing a thorough examination of project conditions.
(c.)They do not provide the contractor any protection from geotechnical risks.
(d.)They provide the contractor some protection from geotechnical risk, but do not eliminate the
contractor's responsibility for performing a thorough examination of project conditions. - (answer)d.)
They provide the contractor some protection from geotechnical risk, but do not eliminate the
