Introduction to Civil Engineering

Study Notes

Civil Engineering Introduction

Civil engineering is one of the oldest engineering disciplines.
It encompasses planning, designing, constructing, maintaining, and operating infrastructure such as buildings, roads, bridges, canals, dams, water supply, and treatment systems.

Civil Engineering Scope

Shelter: Providing essential housing for comfort and safety.
Water Supply Schemes: Designing and constructing water supply systems for drinking and processing.
Buildings and Infrastructure: Creating buildings for machinery, industries, and recreational activities.
Irrigation Works: Constructing irrigation systems to boost food production.
Communication Facilities: Providing roads, railways, bridges, docks, and harbors for efficient communication.
Drainage and Sanitation: Designing and implementing drainage and sanitation systems.

Construction of a Facility

The document highlights various aspects of constructing a facility, potentially focusing on industrial settings
Emphasizes various design and construction elements for different engineering fields:
- Switch Yards
- Chemical Engineering:
  - Construction of chemical storage plants
  - Sheds for chemical storage
  - Petrochemical Plants
  - Water supply for processing
- Electronics & Telecommunication:
  - Transmission & Receiving tower location, design, and erection
- Instrumentation:
  - Air conditioning requirements for specific buildings/rooms (e.g., television studios).
  - Soundproofing needs for certain buildings.

Branches of Civil Engineering

Structural Engineering: Focuses on the structural design and analysis of buildings and infrastructure.
Geotechnical Engineering (Soil Mechanics): Deals with the properties and behavior of soil and rock in relation to construction projects.
Fluid Mechanics: Studies the behavior of fluids (liquids and gases) and their interactions.
Foundation Engineering: Specializes in designing and constructing foundations for structures, ensuring stability.
Transportation Engineering: Focuses on the planning, design, construction, and operation of transportation systems, including roads, railways, and airports.
Environmental Engineering: Addresses the protection of the environment through engineering solutions.
Surveying, Levelling, & Remote Sensing: Involves the measurement and mapping of land using various techniques.
Irrigation Engineering & Water Resource Engineering: Deals with the planning, design, and management of water resources.

Role of Civil Engineering in Various Engineering Fields

Mechanical Engineering:
- Construction of industrial sheds for manufacturing automobiles, compressors, pipes, diesel engines, and heavy vessels.
- Foundation design for machinery installation in industries.
- Design and construction of forging shops.
- Planning material handling systems.
Electrical Engineering:
- Construction of power houses, substations, and transmission line towers.
- Design and construction of underground power houses.

Role of Civil Engineers in Construction Activities

Preparation of layout of the plot:
- Gathering data through investigation, surveys, and research.
- Preparing a detailed layout of the construction site with suitable scale.
Preparation of drawing & approval of drawing:
- Engineers prepare drawings based on the owner's requirements.
- Drawings are submitted for approval.
Preparation of structural design:
- Structural engineers design the structural components using various techniques.
- Calculate and consider different loads on the structure.
Estimation of quantities:
- Engineers estimate the required material quantities using the plan.
- Approximate project cost is calculated based on current market rates.
Preparation of tender document:
- After estimating the approximate cost, a tender document is prepared.
- Quotations are invited from potential contractors.
Execution of Work:
- This includes monitoring various activities on the construction site (testing, supervision).
- Guiding the execution of various work elements.

Properties of Good Bricks

Appearance: Well-burnt, copper-coloured, free from cracks and stones.
Shape and Size: Perfect edges and standard size (19cm x 9cm x 9cm).
Hardness: Sufficiently hard; no impression when scratched with a nail.
Sound: Clear, metallic ringing sound when struck together.
Durability: Strong and durable; should not break easily when struck or dropped.
Water Absorption: Not exceeding 20% when soaked in cold water for 24 hours.
Burning: Neither overburnt nor underburnt.
