Construction Process of Vertical Structures Flashcards
Construction of a residential house process:
- site clearing
- layout and staking
- excavation
- foundation
- framing and masonry
- slab
-roofing works - finishing works
Before starting any construction work, it becomes necessary to clear the place from the unwanted grass, boulder, etc.
Site clearing
In case of any hill like appearance on the ground, that also has to be cleared of the excess earth, and when there’s a pit, it’s required to be filled up. This total job is known as _______.
site clearing
Site clearing includes:
- issues with utilities
- tree obstacles
- buried hazardous materials
- water issues
- problems with obtaining permits
is the process of taking planned improvements and buildings, and then actually mapping them out on the site where the building will take place.
Construction staking
Helps the construction activity adhere to the design requirements of the construction drawings
Layout and staking
Layout and staking also includes:
- Incomplete lot boundary marker
• Inaccurate survey
• Inconsistent construction plan
• Unstable batter boards
are required for footings, foundations, underground utilities, and
other aspects of site development.
Excavation
If foundations are shallow, they are usually dug with a_______.
backhoe
must reach to the depth at which tests have shown the soil to have the
required load-bearing capacity
Exavation
In this foundation trench, a
layer of ______________is laid in the dug portion before placing the reinforcements for
the foundation.
PCC (Plain cement concrete)
Excavation also includes:
- Application of Soil Poisoning
• Excavations collapsing and
burying or injuring people
working in them;
• Falling or dislodging material
• Falling into excavations
• Undermining nearby
structures
• Underground and overhead
services
• Inflow of ground and surface
water
The function of _________is to safely support the loads of the construction above, and transmit them to the ground below.
Foundation
Foundation can be classified as?
Shallow foundation or deep foundation
also serve to resist uplift or overturning forces caused by wind and ground
swelling.
Foundation
are waterproofed with asphaltic or membrane materials to ensure a
watertight system.
Foundation
Foundation also includes:
• Excessive Settlement
• Uneven Settlement
• Water damage
• Tree Roots
These are the vertical structures that hold most of the loads from the superstructure and transfer this weight to the foundation.
Column
These are the horizontal elements within the superstructure that support all the vertical loads.
Beams
refers to a temporary mould into which
is poured and formed so that
it can set to the required
shape.
Formwork
Before installation of Formwork:
- Quality of formwork
- Check for shuttering oil
- Ensure the surface is clean
- Check the installation of reinforcement
Before Concrete Pouring check the following:
- Plumb
- Alignment
- Level
- Dimensions
- Supports
- Any openings
