This document discusses precast concrete construction. Some key points:
- Precast concrete elements are cast and cured off-site then transported for assembly, allowing more efficient production and quality control.
- Elements include slabs, beams, columns, and wall panels that are joined on-site through embedded bolts, plates, and grouted connections.
- The precasting process involves casting concrete around prestressing strands to add strength, then cutting sections and transporting them for erection.
Here are the key steps in the construction of columns:
1. Formwork is erected around the location where the column will be cast. Formwork provides the mould for the column and is usually made of timber or steel.
2. Reinforcing steel (rebar) is assembled and tied together inside the formwork according to design specifications. The rebar helps reinforce the column and improves its load bearing capacity.
3. Concrete is poured into the formwork and around the reinforcing steel. Concrete vibrators are used to consolidate the concrete and remove air pockets.
4. The formwork is stripped after the concrete has cured, typically after 14-21 days. This reveals the finished column.

Prefabrication for improving Sustainability and Economics of Civil Engineerin...Ankit Singhai
The document discusses prefabrication in construction. It defines prefabrication as building components manufactured offsite and transported for assembly. It discusses the history of prefabrication dating back to ancient Rome and its use addressing housing shortages. Modern prefabrication benefits from technology like CAD, CAM, and BIM. Case studies on the Fort Sam Houston medical facility and Stack apartment building show how prefabrication improved schedule and quality. The conclusion is that prefabrication has potential to improve the economy, sustainability, and schedules while addressing issues like labor shortages.
The document discusses a vision for 2020 where construction methods will minimize on-site labor through increased prefabrication. Buildings may become more transportable, able to move or expand as needed. Sustainability and reuse of building materials will drive construction methods and materials.
Introduction of Prefabricated structuresYogi Yogesh
Prefabrication involves assembling building components in a factory and transporting them to the construction site. It aims to reduce costs, improve quality, and speed up construction. Advantages include reduced work time, fewer workers needed, and omitting interruptions. Limitations include size restrictions and transport difficulties. Modular coordination standardizes dimensions. Precast construction allows for industrial quality control while limiting on-site space needs and waste.
This document discusses prefabricated modular structures. Some key points:
1. Prefabricated structures have standardized components that are produced off-site in a controlled environment and then transported for assembly. This allows for faster, more efficient construction.
2. Precast concrete offers advantages like higher quality, less weather dependency, and unlimited design possibilities compared to site-cast construction.
3. There are different precast systems like large panel, frame, and lift-slab. Precast components include walls, floors, beams, and more.

Prefabricated structures involve assembling building components at a factory and transporting them to the construction site. Prefabrication allows for stringent quality control and consistency across repeated housing units. Though still emerging in India, prefabricated construction provides a faster, safer, and more environmentally friendly alternative to traditional building methods.
Cranes are used to lift and lower materials in construction and manufacturing. They can be mounted on vehicles or structures. Operators control the crane and communicate with workers through signals. The largest revolving cranes are found on ships. Common types include mobile, overhead, gantry and tower cranes. Unstable loads, lack of communication, lack of training, and inadequate maintenance or inspection are major causes of crane accidents that can injure operators or others in the area. Regular inspections by a competent person help ensure cranes are safe to use.
The document discusses prefabricated structures and their advantages over traditional construction methods. It notes that prefabricated structures can be built faster, with higher quality, improved safety, and lower costs compared to traditional methods. However, it also outlines some common problems with relocatable prefabricated structures, such as issues with indoor environment quality, flooring, and appearance. The document advocates for future prefabricated structures that can accommodate different climates, architectural styles, and contexts while addressing these common problems.
Use multiple single leg slings to wrap around off-center loads for better stability. Secure all loose equipment before lifting. When using eye bolts or slings, be aware that their capacity decreases significantly at angled loads. Use proper padding and hitches to control loads and prevent damage.
The document discusses lifting equipment and procedures as outlined in the Factories Act. It defines key terms like competent person, machinery, and lifting tackles. It provides guidelines for planning lifts, conducting the lift, landing loads, and dos and don'ts. It also examines sling angles and their effect on safe working loads. Case studies describe incidents where improper planning and techniques like misaligned loads led to injuries.
This document provides an overview of prefabricated modular structures. It discusses the introduction and features of prefabricated structures, comparing them to site-cast structures. It outlines the design concept, components, types of precast systems including large panel, frame, and lift-slab systems. It also discusses design considerations, equipment used, assembly process, scheduling, advantages including reduced costs and time, limitations, and concludes with examples of prefabricated hospital structures.
Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
