Unit 5 Lesson 3-5 Combined Transportation, Manufacturing, Construction

Research In teams of two or three Identify and describe areas of research that you feel would reduce highway construction and maintenance.

Bridge Monitoring Why would it be important to monitor bridge performance? aqo4 aqo4 With a partner research GPS technology to monitor bridge conditions.

Principles of Transportation Systems Transportation systems should be designed and operated in a way that protects the health and safety of all people Transportation needs must be met without generating emissions that threaten public health. Transportation systems must make efficient use of land and other natural resources while ensuring the preservation of vital habitats

Transportation gives large numbers of people today the goods and services that once were luxuries enjoyed only by the wealthy. Transportation plays a vital role in the operation of other technologies, such as manufacturing, construction, communication, health and safety, and agriculture.

Intermodalism Intermodalism is the use of different modes of transportation, such as highways, railways, and waterways, as part of an interconnected system that can move people and goods easily from one mode to another.

Intelligent Vehicles use electronic, electromechanical, and electromagnetic devices to perform precision functions with great reliability. intelligent vehicle technologies are utilized for safety and commercial communications between vehicles or between a vehicle and a sensor along the road.

Manufacturing Think about all of the things you have and who makes them. About 18.5 million American workers (13%) are employed in manufacturing. working in pairs, write down a definition of the term “manufacturing.”

Manufacturing Enterprises Working in pairs list 5 manufacturing enterprises and describe how they affect your life.

Nanotechnology A nanometer is about three to five atoms wide. Nano is the prefix for one billionth (10-9); a nanometer is a billionth of a meter, a millionth of a millimeter. “Like steam engines, electricity, and transistors, nanotechnology is primed to a. completely revolutionize markets, industries, and business models worldwide.”

Manufacturing Steps Designing a product. Obtaining and preparing raw materials. Processing the materials mechanically or chemically. Assembling. Testing. Inspecting. Packaging.

Materials Materials have different qualities and may be classified as natural, synthetic, or mixed.

Manufacturing Systems Manufacturing systems may be classified into types, such as – customized production – batch production – continuous production. The interchangeability of parts increases the effectiveness of manufacturing processes

Goods Durable goods are designed to operate for a long period of time while non-durable goods are designed to operate for a short period of time.

Construction Technology Think about the energy used in commercial buildings. Commercial buildings include a wide variety of building types—offices, hospitals, schools, police stations, places of worship, warehouses, hotels, barber shops, libraries, and shopping areas.

Commercial Buildings Commercial buildings use more than half of the energy for heating and lighting. Electricity55% Natural Gas32% District Heat10% Fuel Oil 3% Electricity and natural gas are the most common energy sources used in commercial buildings.

Commercial Buildings Commercial building owners in the United States spend almost $100 billion per year on their energy bills. new technologies and better systems integration can lead to a savings of 50 percent or better in new buildings.

Commercial Buildings Students, working in pairs, will brainstorm, do some preliminary research, and create a list of design ideas for commercial buildings that might cut energy costs.

Facts that Influence Commercial Design Accessibility Aesthetics Cost-efficiency Functionality Historic Preservation Productivity Security and Safety Sustainability

Influences Accessibility – Pertains to building elements, heights, and clearances implemented to address the specific needs of disabled people. Aesthetics – Pertains to the physical appearance and image of building elements and spaces as well as the integrated design process.

Influences Cost-efficiency – Pertains to selecting building elements on the basis of life-cycle costs (weighing options during concepts, design development, and value engineering) as well as basic cost-estimating and budget control. Functionality – Pertains to functional programming—spatial needs and requirements, system performance, as well as durability and efficient maintenance of building elements

Influences Historic Preservation – Pertains to specific actions within an historic district or e. affecting an historic building whereby building elements and strategies are classifiable into one of the four approaches: preservation, rehabilitation, restoration, or reconstruction. Productivity – Pertains to occupants’ well-being— physical and psychological f. comfort—including building elements such as air distribution, lighting, workspaces, systems, and technology.

Influences Security and Safety – Pertains to the physical protection of occupants and assets from man- made and natural hazards. Sustainability – Pertains to environmental performance of building elements and strategies.

“whole building design,” a process being promoted by the U.S. Department of Energy. Considers all building components during the design phase. Integrates all the subsystems and parts of the building to work together. Requires the design team to be fully integrated from the beginning of the process.

“whole building design include: Reduced energy use (50% or more). Reduced maintenance and capital costs. Reduced environmental impact. Increased occupant comfort and health. Increased employee productivity.

Building Design High-performance building design attempts to ensure complete integration to achieve optimal building performance. “Going Green”

Combination Students will design, build, and test a functional Hover Craft that will support human weight. Students will use the Engineering Design Process Portfolio to complete the design. After portfolio students will Analyze the Hover Craft.
