#2
What is the purpose of a construction punch list?
To document final inspections and remaining work
ExplanationA punch list details any remaining work or defects that need to be addressed before project completion.
#3
What is the purpose of a construction closeout process?
To document final inspections and remaining work
ExplanationThe closeout process involves final inspections, documentation, and completion of any remaining tasks before project handover.
#4
What is the primary purpose of a construction submittal?
To gain approval for materials, products, or processes
ExplanationSubmittals provide detailed information about materials, products, or processes for approval by project stakeholders.
#5
What is the purpose of formwork in construction?
To provide structural stability
ExplanationFormwork supports freshly placed concrete until it sets and gains sufficient strength.
#6
Which construction technique is commonly used for building tall structures like skyscrapers?
Cast-in-place concrete construction
ExplanationThis method involves pouring concrete into forms onsite, allowing for customized designs and structural integrity.
#7
Which construction method involves assembling pre-manufactured components on-site?
Prefab construction
ExplanationPrefab construction involves assembling pre-made components at the construction site, reducing construction time and costs.
#8
What is the purpose of a construction change order?
To modify project specifications
ExplanationA change order is issued to modify project plans, specifications, or scope after construction has commenced.
#9
Which construction method involves using pre-cast concrete panels that are tilted into position?
Tilt-up construction
ExplanationTilt-up construction involves casting concrete panels on-site, then tilting them into place to form walls.
#10
What is the purpose of a geotextile in construction?
To control erosion
ExplanationGeotextiles prevent soil erosion by stabilizing slopes, retaining soil, and allowing water to drain.
#11
In construction, what does the term 'LEED' stand for?
Leadership in Energy and Environmental Design
ExplanationLEED is a rating system that promotes sustainable building practices, focusing on energy efficiency and environmental impact.
#12
Which construction material is known for its high strength-to-weight ratio and corrosion resistance?
