Project Sitework Flashcards
(36 cards)
What is the purpose of grading in sitework?
To create a level base or specific slope for construction.
What is cut and fill?
Cut involves removing soil, while fill involves adding soil to achieve desired grades.
What is the mass diagram used for?
To determine the volume and movement of earth in cut and fill operations.
How is earthwork volume commonly calculated?
Using average end area or grid methods.
What is site layout in construction?
The arrangement of construction elements and temporary facilities on-site.
What is construction staking?
Placing stakes to guide excavation, grading, and construction.
Why is survey control important in construction?
To ensure structures are built in the correct location and elevation.
What are benchmarks used for?
To provide elevation reference points on a construction site.
What is the goal of erosion and sediment control?
To prevent soil erosion and keep sediment on-site during construction.
What is a silt fence?
A temporary barrier used to trap sediment on construction sites.
What is sediment transport?
The movement of eroded soil by water or wind.
What is channel protection in erosion control?
Stabilizing channels to prevent erosion from concentrated flows.
What is a construction stormwater permit?
A permit required under the Clean Water Act for sites disturbing more than one acre.
What are best management practices (BMPs) in construction?
Techniques to control pollutants and prevent erosion.
How can construction impact adjacent facilities?
By causing vibrations, noise, dust, access restrictions, and structural damage.
What is underpinning?
Strengthening the foundation of an existing structure adjacent to construction.
What is a pre-construction survey?
A documentation of nearby structures’ conditions before starting construction.
How can groundwater pumping affect nearby buildings?
It can cause ground settlement and damage to foundations.
Why is construction safety important?
To protect workers and the public from injury or death.
What are typical work zone safety measures?
Barriers, signage, flaggers, lighting, and reduced speed limits.
What is a traffic control plan?
A plan to safely manage traffic during construction.
What is a trench safety requirement?
Use of shoring, shielding, or sloping to prevent collapse in trenches over 5 feet deep.
What is the point of curvature (PC)?
The point where a horizontal curve begins.
What is the point of tangency (PT)?
The point where a curve ends and returns to a straight section.
