Mass diagrams tell the contractors and inspectors the quantity of material moved and how far it can be economically Size: KB. Overhaul: Is the number of cubic meters (yards) of overhauled material multiplied by the overhaul distance, this distance is measured between the center of gravity of cut and fill (i.e.

Freehaul Distance (F.H.D.) + Economic Overhaul Distance(Limit) (O.H.D.) - Economic Overhaul Distance = Cost of Borrow / Cost of Overhaul - Freehaul: Distance with which there is a fixed price for excavating, hauling, and dumping regardless of the distance moved.

Free-haul is part of the haul which is contained within the free haul distance. • Over-haul Distance: is the distance in excess of the free-haul distance, over which it is necessary to transport material. An extra charge will be paid for transport. Over-haul is part of the haul which remains.

Average haul determined from mass diagram. Average haul is the area of the mass diagram representing the number of cubic yard stations of haul between balance points divided by the ordinate of the mass which the yardage is hauled.
Overhaul the authorized hauling of excavation beyond the specified free-haul distance. Earthwork includes the excavation of existing earth material and any placement of fill material required for constructing the embankment. The manual method for determining earth excavation and embankment amounts involves three steps: cross sections of the proposed highway are placed on the original ground cross sections, the areas in cut and.
Overhaul Exceptions Overhaul is paid for when you exceed the average or free haul distance. Overhaul is only paid if you are outside of the balance points. This means that if your average or free haul distance is exceeded within the balance point, you do NOT have to pay for overhaul.
Economic Overhaul Distance = Cost of Borrow / Cost of Overhaul Freehaul: Distance with which there is a fixed price for excavating, hauling, and dumping regardless of the distance moved.

Earth Work Haul and Overhaul Including Economic Distribution () Engineering Economics, First Principles 1st edition, () which was the leading text for the next 20 years.
Fish completely rewrote the second edition in which proved to be more significant than his first. The Engineering Profession (). Mass Haul Diagram. This is a curve representing cumulative volume of earthwork at any point on curve, the manner which earth to be removed.
It is necessary to plan movement of excavated soil of work site from cuts to fill so that haul distance be minimum to reduce the cost of earthwork. The major cost factors of a solar pond system are the earthwork (excavation, leveling, and compaction), the synthetic lining, the salt, the water, the land, and other miscellaneous supplies.
These factors vary considerably with the location and the size of the system. Consequently, small ponds are considerably more expensive than large ponds, and there is a wide variability in the per unit. earthwork sites can be evaluated to more broadly quantify the many factors affecting earthwork productivity.
Key Words Distribution Statement. autonomous earthwork technologies—earthwork—haul truck cycle time No restrictions. Security Classification (of this report) Security Classification (of this page) No. of Pages INTRODUCTION Mass-haul diagrams (MHD) are used to compare the economicsof the various methods of earthwork distribution on road or railwayconstruction schemes.
With the combined use of the MHD plotteddirectly below the longitudinal section of the survey centre-line, onecan find: The distances over which ‘cut and fill’ will balance.
The overhaul volume for section BCD is given by the difference between the ordinates from c to bd and from c to 1– –2.
The average length of overhaul is estimated by drawing the balance line 7–8 through the median of the overhaul ordinate. Since the freehaul distance- is given by 1–2, the average overhaul.
EARTHWORK CALCULATION SPREADSHEET The spreadsheet “Any Level Method” is used to compute the volume of earthwork. This spreadsheet uses the Any Level Method (Coordinate Method) to compute the end area of the embankment or excavation at a given Station. Earth fill and excavation yardage must be entered and calculated on separate spreadsheets.
Section - Earthwork and Site Work 2/5/ provide a uniform distribution of moisture in the material. The application of water to the compaction operation and shall repair all damage at his own expense.
C Seasonal Limits No fill material shall be placed, spread, or rolled while it is frozen or thawing, or during. Represent free haul and overhaul volumes using grade point and balance point methods.
During project development, contractors and design engineers may try to balance the mass haul requirements by considering free haul distances, any overhaul, and the use of borrow pits for embankments and dump sites for extra excavated volumes, based on the economic haul limits and the site conditions.
Nothing can be built without some excavation and transfer of soil (or rock) from one part of a site to another and this makes earthworks the most common product of civil engineering operations. Although normally seen as major structures, such as earth fill dams or large highways or railway embankments, the majority of earthworks are connected with minor civil works and building construction.
Acquiring desired topography via exporting earth material from the work site. 3) Filling Acquiring desired topography via importing earth material into the work site.
Calculation Methods; Modern day tools including GPS, Total Station, LIDAR and Microsoft Excel have redefined how earthwork modeling volume calculations are derived.

including merchant chests. • Earthwork should balance at major highway intersections, both sides of towns, rivers or major streams or other natural breaks.
Do not haul across bridges or through towns if possible. • An earthwork analysis should be developed and quantities shown on plans for each phase of construction, for information only. Earthworks operations include the excavation, transport, placement and compaction of fill materials to construct earth structures, and is a significant element of almost all civil engineering projects.
A good understanding of earthworks design and construction enables the delivery of successful projects and avoidance of costly problems. Chapter 2 Earthwork Clearing, Grubbing, and Roadside Cleanup SS Construction Requirements SS (1) Clearing Before starting grading operations, it is necessary to prepare the work area by removing all trees, brush, buildings, and other objectionable material and obstructions that may interfere with the construction of the roadway.
Earthwork is something that transportation projects seldom avoid. In order to establish a properly functional road, the terrain must often be adjusted. In many situations, geometric design will often involve minimizing the cost of earthwork movement.
Earthwork is expressed in units of volumes (cubic meters in metric). E1 depends on earth mov ing met hod, co-o perati ng equi pment, wo rking conditio n, h auling distance, maintenance condition of equipment, etc. （E 1 ＝ ～ ） E 2 is working ability rate that depends on soil condition, weather condition.

Completely revised throughout for the latest methods, equipment, and regulations, Moving the Earth, Sixth Edition is the industry-standard source of practical expertise for the excavation and construction industries.
This all-inclusive workbook covers every aspect of site preparation and management, and details every machine and vehicle needed. This tutorial demonstrates how to create and edit mass haul diagrams to display earthworks in profile. Mass haul is defined as the volume of material multiplied by the distance it is moved during construction.
A mass haul diagram consists of two objects: a mass haul line, and a mass haul view. The mass haul line represents the free haul and overhaul volumes in cut and fill conditions along an.The mission of the Houston Area Urban League is to enable African Americans and other minorities to secure economic self-reliance, parity, power and civil rights.
Our Organization The Houston Area Urban League (HAUL) was organized in June, as a nonprofit (c)3 agency.An example using the mass haul diagram below will be used to illustrate the procedure for determining the amount of overhaul and cost estimation of such an operation.
The freehaul in this example is ft and the cost of overhaul is $ per yd 3 sta. Figure 2 Mass Haul Diagram for Example Step 1 Plot the Mass Haul Diagram with the Mass ordinate on the y-axis and the station on the x-axis.
