Asphalt Road Construction

Why dont we use concrete instead? Concrete has evolved in the use of highways and roadways to be superior in terms of resistance to wear and tear as compared to asphalt. It is "greener" to use. My fear is that we use asphalt to secure construction jobs as it has to be continually maintained, especially in cold weather climates where pot holes are born after constant cold retraction, heat expansion and salt during winter weather. From what I can tell… Concrete is made from Portland cement and gravel. Portland cement is made by reducing limestone- by crushing it, then heating it with natural gas. The reason concrete costs more than asphalt is because it is, actually, very energy intensive to manufacture; must be used when mixed; and is more labor intensive to lay. Asphalt is used because it is smooth and quiet, and cheap. The machines to lay it can deposit, compact, and smooth the asphalt in a continuous operation, greatly reducing road closure time for resurfacing. Concrete gets very rough and noisy after it has been there for a while, especially on highways, as the cement is worn away and the aggregate is exposed. It's vulnerable to cracks and potholes too. As for the 'almighty dollar-' it's tax money used to pay for it. Usually the least expensive material is less harmful, in total, to the environment, having consumed the least resources and labor.

What are the associated costs with recycling waste in construction. I was happy to learn… Construction waste recycling is the separation and recycling of recoverable waste materials generated during construction and remodeling. Packaging, new material scraps and old materials and debris all constitute potentially recoverable materials. In renovation, appliances, masonry materials, doors and windows are recyclable. Most construction waste goes into landfills, increasing the burden on landfill loading and operation. Waste from sources such as solvents or chemically treated wood can result in soil and water pollution. Some materials can be recycled directly into the same product for re-use. Others can be reconstituted into other usable products. Unfortunately, recycling that requires reprocessing is not usually economically feasible unless a facility using recycled resources is located near the material source. Many construction waste materials that are still usable can be donated to non-profit organizations. This keeps the material out of the landfill and supports a good cause. The most important step for recycling of construction waste is on-site separation. Initially, this will take some extra effort and training of construction personnel. Once separation habits are established, on-site separation can be done at little or no additional cost.

Highway Road Construction

Million dollars for constructing 40 km of a similar highway. Based on these costs and assuming a linear relationship exists between the total cost and the length of road constucted, determine the cost of constructing a) 25 km of similar highway b) 52km of similar highway. From what I can tell… Since there is a linear relationship between the cost C (in millions of dollars) and the length x (in kilometers) of road constructed, we can say that: C(x) = ax + b . . Where a and b are constants. We can use the initial values given in the problem statement to calculate values for a and b. We're given that: C(20) = 125 => 20a + b = 125 *** EQUATION 1 Also, we're given that: C(40) = 245 => 40a + b = 245 *** EQUATION 2 Multiplying 2 Eq. 1, and subtracting Eq. 2, we get: 40a + 2b = 250 (-) 40a + b = 245 ——————— b = 5 Substituting b = 5 into either Eq. 1 or Eq. 2, we get: 40a = 240 => a = 6 So, now we have our values for a and b, and our expression for C(x) is: C(x) = 6x + 5 To solve the problems, all we need to do is plug in values for x. PART A We're asked to find C(25): C(25) = 6(25) + 5 = $155 million PART B We're asked to find C(52): C(52) = 6(52) + 5 = $317 million

Building Construction

Picture of the tool and its use. Basically… 1. Building and construction tools and machines include hand tools and power tools used in the building and construction industry.

2. Air Compressors – Air compressors are machines that compress air to higher than atmospheric pressures for delivery to pneumatic or robotic tools, industrial equipment, or direct-use applications.

3. Hammers – Hammers are simple, usually hand-held tools intended to deliver impact force to an object using a non-rotary force. They can be powered or manually-driven.

4. Hand Saws – Hand saws are hand-held tools, either powered or manually-driven, that are designed to cut through softer materials. They accomplish cutting using a hard, serrated blade, or by using a wire with an abrasive edge.

5. Hand Tools – Hand tools are manually-operated tools that fit in the hand.

6. Levels – Levels are mechanical or electronic tools that measure the inclination of a surface relative to the earth's surface. Levels vary from simple mechanical devices to complex electronic sensors that digitally readout angular level values.

7. Nailers – Nailers, also referred to as nail guns, are tools used to drive nails and brads into wood, concrete and other materials. Nailers are usually electrically or pneumatically powered, however some applications, such as flooring installation, use manually powered nailers.

8. Pliers – Pliers (plyers) are handheld, manually-powered hand tools, often employing serrated jaws, designed for holding, cutting, bending, or manipulation of tough or difficult materials such as wire, sheet metal, or fine machine components.

9. Power Tools – Power tools include a wide range of devices for fabrication, assembly, construction, and repair. They are usually motor-driven.

10. Screwdrivers (electric and pneumatic) – Industrial screwdrivers and screwfeeders are automated tools that are used to turn screws while providing close control of screw torque. They can be electric or pneumatic and may include features such as torque feedback and controlled stopping. 11. Screwdrivers (hand tool) – Screwdrivers, also known as turn screws, are hand-held, manually-powered simple implements designed for insertion and tightening of screws. 12. Staplers – Staplers are handheld tools used to drive staples. Staplers can be divided into two main categories; those used in desk or office applications for joining sheets of paper, and those used in construction applications to drive staples into wood or masonry. 13. Workbenches and Workstations (Industrial) – Industrial workbenches and industrial workstations are locations where personnel perform work. Products range from economy workbenches to cleanroom and electronic assembly benches. 14. Wrenches – Wrenches, also known as spanners, are hand-held tools designed to provide a mechanical advantage in applying torque for turning bolts, nuts, and other wrench-friendly objects.

Construction Project Manager

I was reading and it said that someone was just graduating as a construction project manager. Does that mean they went to college for the whole four years or is it just a few classes you have to take and you get a certificate or something. Well, I have your answer right here. Rupert, You can learn more at this link: #training Education and training. For construction manager jobs, a bachelor's degree in construction science, construction management, building science, or civil engineering, plus work experience, is becoming the norm. However, years of experience, along with taking classes in the field or getting an associates degree, can substitute for a bachelors degree. Practical construction experience is very important for entering this occupation, whether earned through an internship, a cooperative education program, a job in the construction trades, or another job in the industry. Some people advance to construction management positions after having substantial experience as construction craftworkerscarpenters, masons, plumbers, or electricians, for exampleor after having worked as construction supervisors or as owners of independent specialty contracting firms. However, as construction processes become increasingly complex, employers are placing more importance on specialized education after high school. More than 100 colleges and universities offer bachelor's degree programs in construction science, building science, and construction engineering. These programs include courses in project control and development, site planning, design, construction methods, construction materials, value analysis, cost estimating, scheduling, contract administration, accounting, business and financial management, safety, building codes and standards, inspection procedures, engineering and architectural sciences, mathematics, statistics, and info technology. Graduates from 4-year degree programs mostly are hired as assistants to project managers, field engineers, schedulers, or cost estimators. An increasing number of graduates in related fieldsengineering or architecture, for examplealso enter construction management, often after acquiring substantial experience on construction projects. Several colleges and universities offer a master's degree program in construction management or construction science. Master's degree recipients, especially those with work experience in construction, typically become construction managers in very large construction or construction management companies. Often, individuals whoever hold a bachelor's degree in an unrelated field seek a master's degree in construction management or construction science to work in the construction industry. Some construction managers obtain a master's degree in business administration or finance to further their career prospects. A number of 2-year colleges throughout the country offer construction management or construction technology programs. Several individuals also attend training and educational programs sponsored by industry associations, often in collaboration with postsecondary institutions. Other qualifications. Construction managers should be flexible and work effectively in a fast-paced environment. They should be decisive and work well under pressure, particularly when faced with unexpected events or delays. The capability to manage several major activities at once, while analyzing and resolving specific problems, is essential, as is an understanding of engineering, architectural, and other construction drawings. Familiarity with computers and software programs for job costing, online collaboration, scheduling, and estimating also is important.

Commercial Construction

So my dad has a company in residential and ya it makes good money but a friend I just picked up this year dad is commercial and residential and hired my dad on this 12 million dollar job thats the type of money im looking for how do I get into commercial construction as starting a buisness for myself. After looking around, I learned — Go to work from your friend's dad. Get any experience and save any money Find out what kind of profit margin he has. Large contracts often have small profit margins. You should already know this since you dad is in the business; but the construction business is very competitive and business turnover is high, The following is from the source listed below. "Opportunities for workers to form their own firms are better in construction than in many other industries. Construction workers may need only a moderate financial investment to become contractors and they can run their businesses from their homes, hiring additional construction workers only as needed for specific projects. The contract construction field, however, is very competitive, and the rate of business turnover is high. Taking courses in business helps to improve the likelihood of success. " "Managerial personnel mostly have a college degree or considerable experience in their specialty. Individuals who enter construction with college degrees mostly start as management trainees or as assistants to construction managers. Those who receive degrees in construction science often start as field engineers, schedulers, or cost estimators. College graduates may advance to positions such as assistant manager, construction manager, general superintendent, cost estimator, construction building inspector, general manager or top executive, contractor, or consultant. Although a college education is not always required, administrative jobs mostly are filled by those with degrees in business administration, finance, accounting, or similar field"
