Heavy equipment is essential for construction jobs of almost any size, from home building to large-scale commercial and civil projects. Earth-moving equipment covers a broad range of machines that can excavate and grade soil and rock, along with other jobs. Earth movers and other heavy equipment help to speed not only earth work but also materials handling, demolition, and construction.

Table of Contents

Ibrahim A. Prerequisite: ENCE and permission of department. Senior standing. Evaluation and selection of equipment and methods for construction of projects, including earthmoving, paving, steel and concrete construction, formwork, trenching, cofferdams, rock excavation, tunneling, site preparation and organization. Design of formwork, trench supports, and cofferdams.

Professional presentation consists of neat and organized solution of problems on one side of 8. Any homework not complying with professional standards will not be graded and will be assigned zero credit. The homework assignments are due one week after they are assigned. Homework will be assigned as the material is covered and will be collected every Monday at the beginning of the lecture period. Solutions will be available from the TAs and on the class website after the problems are returned.

No assignment will be accepted after the answers have been posted. Students are encouraged to discuss and formulate solutions to the problems by working in teams. However, assignments must be completed and submitted individually. Simply copying the answers from another student or from a solutions manual is not acceptable and will not be tolerated.

Use good quality paper, such as engineering graph paper or college-ruled paper, any color, with no spiral edges. Write on only one side of the paper.

Either pen or pencil is acceptable. Include your name, section, and page number e. Staple all pages together in the upper left corner. Neatly box all answers, and include appropriate units for numerical answers. Show all work e. Only extenuating circumstances will be accepted as excuse for missing an exam. Health related excuses require medical reports and the signature of a physician that provided treatment.

Construction of engineered facilities requires the utilization of construction equipment. Learn to apply engineering fundamentals and analyses to the planning, selection, and utilization of construction equipment. Through understanding of: 1 The total construction process, from inspection of the idea through construction and start up, and 2 How construction equipment should be selected and used to produce the intended quality in the most cost-effective manner.

Proctor initiated a scientific study to determine the density- moisture relationship of soils. This is a prerequisite of a good machine. Draglines 2. Clamshells 3. Hydraulic excavators a.

Front shovels b. Hoes 4. Loaders a. Wheel b. Track 5. Trenching machines. The size and type of engine-gasoline, diesel, butane, propane 2. The number of gears 3. The kind of drive-two-wheel, four-wheel, six-wheel, etc. The number of wheels and axles and arrangement of driving wheels 5. The method of dumping the load-rear-clump, side-dump 6.

The class of material hauled-earth, rock, coal, ore, etc. The capacity, in tons or cubic yards. Crawler 2. Hydraulic truck 3. Lattice-boom truck 4. Rough-terrain 5. All-terrain 6. Heavy lift 7.

Modified cranes for heavy lift 8. Equipment for Pumping Water Chapter 20 Pumps are used extensively on construction projects for: 1. Removing water from pits, tunnels. Dewatering cofferdams. Furnishing water for jetting and sluicing. Furnishing water for many types of utility services. Lowering the water table for excavations. Foundation grouting. Note: During the construction of the Channel Tunnel between England and France conveyors were used to move up to 2, tons of spoil per hour from the tunnel headings.

Newman, Western Australia. The faster and better they perform, the sooner they will be looking for another project to build. Construction contracts must contain four legal items to be valid: 1. This means that both parties must be of sufficient age to enter into a contract and mentally aware of what they are doing. For a contract to be valid, it must be legal. Obviously, a contract between two parties in which one agrees to commit an illegal act cannot be enforced! The units of work may be any items whose quantities can be determined e.

At each site the constructor erects a construction plant specifically designed for that project. It is usually bid on a unit-price basis and can be subject to large variations between estimated and actual quantities. Highway work is usually spread over several miles, making its control and management very difficult. Speed of pipeline work requires constructors to keep current on job costs and overruns.

Design concrete structures with as many duplicate members as practical. Simplify the design of the structure where possible.

Design for the use of cost-saving equipment and methods. Eliminate unnecessary special construction requirements. Design to minimize labor-intensive activities. Specify a quality of workmanship that is consistent with required project quality. Furnish adequate subsurface information where possible. Construction Economics and the Designer 8. Refrain from requiring the constructor to assume the adequacy of design or the responsibility for information that should be furnished by the engineer or architect.

Use local materials when they are satisfactory. Write simple, straightforward specifications, which clearly state what, is expected. Define either the results expected or the methods of accomplishing the desired results, but not both. When possible, use standardized specifications, which are familiar to the constructors.

Hold pre-bidding conferences with constructors in order to eliminate uncertainties. Use inspectors who have sufficient judgment and experience to understand the project and to give them the authority to make decisions.

If she does not pay back any of the amount owed after one year, then normally the interest owed, but not paid, is considered now to be additional principal, and thus the interest is compounded. The three values are not equal but equivalent. Note: 1. The concept of equivalence involves time and a specified rate of interest. Equivalence means that one sum or series differs from another only by the accumulated interest at rate i for n periods of time.

Note: F is related to P by a factor which depends only on i and n. If she pays back the loan and accumulated interest after 8 months, how much will she have to pay back? Uniform Series of Payments Analysis Which can be expressed in a functional form as.

How much should the owner of the equipment charge, per hour of use, if he expects to use the piece of equipment about 1, hours per year? The MARR is usually equal to the current rate of interest for borrowed capital plus an additional rate for such factors as risk, uncertainty, and contingencies. The alternatives are: A. The contractor pays all operating and maintenance costs on the pickups and the leasing company retains ownership. Note: All alternatives involve equal lives.

What to do When Alternatives Involve Different Lives Approach 1: Truncate cut off the longer-lived alternative s to equal the shorter lived alternative and assume a salvage value for the unused portion of the longer lived alternatives.

Сьюзан не могла с этим смириться, видя, как он выкладывает за их обед свою дневную заработную плату, но спорить с ним было бесполезно. Она в конце концов перестала протестовать, но это продолжало ее беспокоить. Я зарабатываю гораздо больше, чем в состоянии потратить, - думала она, - поэтому будет вполне естественным, если я буду платить. Но если не считать его изрядно устаревших представлений о рыцарстве, Дэвид, по мнению Сьюзан, вполне соответствовал образцу идеального мужчины. Внимательный и заботливый, умный, с прекрасным чувством юмора и, самое главное, искренне интересующийся тем, что она делает.

 - Она едва заметно подмигнула.  - В этом все и. - Мидж… - Доброй ночи, Чед.  - Она направилась к двери.
