Study Notes

Geotechnical Engineering

Geotechnical Engineering is a branch of Civil Engineering
It deals with the engineering behavior of earth materials
This includes investigating subsurface conditions and materials
It determines physical/mechanical and chemical properties of these materials
It assesses risks posed by site conditions
It designs earthworks and structure foundations, and monitors site conditions
It encompasses soil mechanics, rock mechanics, foundation engineering, soil dynamics, earthworks engineering, earth retaining structures, pavement engineering, ground improvement, coastal and ocean engineering

Soil Mechanics

Soil is defined as a mixture of mineral grains and decayed organic matter
Soil particles are dispersed in liquid and gas spaces between them
Soil is a crucial construction material supporting structural foundations
Important soil properties include origin, grain-size distribution, drainage ability, water compressibility, shear strength, and load-bearing capacity
Soil mechanics studies soil's physical properties and behavior under various forces
Soil engineering applies soil mechanics principles to solve practical problems

Origin and Formation of Soil

Soil forms from the weathering of rocks
Weathering is the disintegration and decomposition of rocks through natural and chemical agents
Smaller rock pieces are produced through both mechanical and chemical processes leading to smaller grains
Weathering involves various processes, including physical actions of water, ice, wind, and chemical reactions with materials

Residual and Transported Soils

Residual soils are weathered products that remain in their original locations
Important characteristics of residual soils include the gradation of particle size, with fine-grained soil typically found closer to the surface
Transported soils are formed by weathering, then moved from their original location
Transported soils are categorized based on their transportation and deposition methods, including glacially transported, alluvially transported, lacustrine, marine, aeolian, and colluvially transported

Building Components

A building comprises two main parts: super-structure and sub-structure.
The structure above the ground level is referred to as the super-structure
Foundation is a part of sub-structure that sits at the bottom.

Foundation Types

Foundations are categorized as shallow and deep foundations
Shallow foundations have a depth equal to or less than their width
Shallow foundations are further grouped into spread footings, combined footings, strap footings, and raft or mat foundations
Deep foundations have a depth more than their width
In deep foundations, pile foundations, pier foundations, and caisson or well foundations are common types

Shallow Foundations (Open Foundations)

Types of shallow foundations include spread footings, strip footings, isolated/pad footings, combined footings and grillage, and raft/mat foundations
Spread footings rest beneath walls and columns spreading the load
Strip footing supports continuous walls
Isolated/pad footing supports individual columns
Combined footings support two or more columns
Grillage foundations support heavily loaded steel stanchions in soil with poor bearing capacity
Raft/mat foundations support all walls and columns beneath a building

Deep Foundations

Deep foundations transmit loads through weak soil to strong soil beds or rock beds
Deep foundations are applied when the soil in a reasonable depth lacks the desired bearing capacity (like shallow soil)
Common types are pile foundations, pier foundations, and caisson foundations

Pile Foundation

Pile foundations use vertical members such as timber, concrete, or steel
Loads are transferred to a lower level by these members

Pier Foundation

Pier foundations are vertical columns, with a larger cross-section than piles.
They are installed in a dry area by excavating a cylindrical hole and backfilling with concrete.
Often used when driving piles through highly resistant decomposed rock is difficult.

Caisson/Well Foundation

Caissons are prefabricated hollow substructures used in locations that are often in water
Sunk in the ground to the desired depth, then filled with concrete to become an integral part of the permanent structure

Foundation Importance

Foundations anchor a building's mass and spread loads uniformly
They define the structure's lateral stability.
Foundation properties affect natural movement of soil, protect the structure from forces like weather and mold, and protect against heat and cold.
Prevent settlement and subsidence, and preserve the structure from water and moisture damage.

Automation and Robotics in Construction

Automation and robotics enhance construction productivity, safety, and efficiency
Automated machinery (like bulldozers, excavators, and cranes) improve performance in tasks like excavation and material handling
Drones can survey and map construction sites, creating 3D models to monitor progress and identify issues
BIM (Building Information Modeling) is a digital representation of buildings to optimize processes
Robots perform tasks like bricklaying, welding, and concrete spraying, offering higher precision and speed
Autonomous vehicles are used for material and equipment transport, improving 24/7 operation

Sustainability in Civil Engineering

Sustainability in civil engineering involves infrastructure design and construction to minimize environmental and societal impact while maximizing economic benefits
This concept encompasses three pillars: environmental sustainability; social sustainability; and economic sustainability
Green infrastructure uses natural systems like green roofs and rain gardens for stormwater management and urban heat island reduction
Sustainable materials (recycled content materials) are prioritized to lessen environmental impact
Life-cycle assessment guides design decisions to minimize environmental impact
Energy-efficient building designs are crucial to reducing energy consumption and greenhouse gas emissions
Promoting sustainable transportation options (walking, cycling, public transit) improves air quality and reduces emissions
Sustainable infrastructure creates more resilient and affordable environments for communities to improve social well-being

Smart City

A smart city integrates technology and data-driven solutions to improve the quality of life for residents and enhance sustainability
Digital solutions support urban services, including transportation, energy, waste management, and public safety.
Data-driven decision-making allows optimized urban planning, and service delivery, and resource allocation.
Data collected can enable effective solutions based on real-time conditions or behaviors.
