Construction Flashcards
Treatment might be made to improve the level of service
Realigning roadway to improve sight distance and adding a passing lane
(Impact speed or coefficient of friction) produces the greatest possible error…
The coefficient of friction is more sensitive to error
A line on a topographic map connecting points of equal elevation
Contour line
True statement regarding a neat line on an excavation drawing
The contractor will not normally be paid for excavating beyond neat line
Green’s theorem
Surface area of a construction site to be surfaced
Balance dirt job
Cut and fill volumes are equal
Installation instructions for erosion control features…INCORRECT
Install a silt fence…BELOW THE HIGHT WATER LEVEL…channel
Prior to settling elevation stakes on a small construction site a surveyor is most likely to
Establish a local control
Preferred method to avoid negative stations in a construction document
Station 0+00 is selected some significant distance from the project boundary
A robotic total station
AOTA
Primary cause of accident that is characterized by the human action
Unsafe act
In demolition safety, this control is ENSURING SEPARATION between the public and the demolition activities
Elimination
process of PROPORTIONING the cement…
batching
LEVELLING of concrete layer
moving a straight-end back and forth
screeding
WEARING way of pavement due to insufficient asphalt
Ravelling
most important process to prepare concrete
batching
test to determine CONSISTENCY of concrete
slump test
it details how facility to be constructed
detailed requirements for the materials
specification
Bulk volume of concrete
aggregates
most important factor in concrete mix
water-cement ratio
deviation from standard condition
Hazard
promote hydration during early stage of hardening
curing
combination of likelihood of an occurrence and severity
risk
occurs as concrete hardens, being greater in wet mixes
shrinkage
