2. Construction estimating software - Wikipedia

   en.wikipedia.org/wiki/Construction_estimating...

   The SharpeSoft Estimator, displaying an example of a trench calculation. Calculations: Most estimating programs have built-in calculations ranging from simple length, area, and volume calculations to complex industry-specific calculations, such as electrical calculations, utility trench calculations, and earthwork cut and fill calculations.

3. Earthworks (engineering) - Wikipedia

   en.wikipedia.org/wiki/Earthworks_(engineering)

   In the past, these calculations were done by hand using a slide rule and with methods such as Simpson's rule. Earthworks cost is a function of hauled amount x hauled distance. The goal of mass haul planning is to determine these amounts and the goal of mass haul optimization is to minimize either or both. [2]

4. Cut and fill - Wikipedia

   en.wikipedia.org/wiki/Cut_and_fill

   A mass haul diagram where land and rock cuts are hauled to fills Fill construction in 1909 Cut & Fill Software showing cut areas highlighted in red and fill areas shaded in blue. In earthmoving , cut and fill is the process of constructing a railway , road or canal whereby the amount of material from cuts roughly matches the amount of fill ...

5. Cut (earthworks) - Wikipedia

   en.wikipedia.org/wiki/Cut_(earthworks)

   In civil engineering, a cut or cutting is where soil or rock from a relative rise is removed. Cuts are typically used in road, rail, and canal construction to reduce a route's length and grade. Cut and fill construction uses the spoils from cuts to fill in defiles to create straight routes at steady grades cost-effectively.

6. Mathematical optimization - Wikipedia

   en.wikipedia.org/wiki/Mathematical_optimization

   Methods that evaluate gradients, or approximate gradients in some way (or even subgradients): Coordinate descent methods: Algorithms which update a single coordinate in each iteration; Conjugate gradient methods: Iterative methods for large problems. (In theory, these methods terminate in a finite number of steps with quadratic objective ...

7. Slurry wall - Wikipedia

   en.wikipedia.org/wiki/Slurry_wall

   Slurry walls are used at Superfund sites to contain the waste or contamination and reduce potential future migration of waste constituents, often with other waste treatment methods. Slurry walls are a "well-established" technology but the decision to use slurry walls for a certain project requires geophysical and other engineering studies to ...

9. Wheel tractor-scraper - Wikipedia

   en.wikipedia.org/wiki/Wheel_tractor-scraper

   The horsepower of the machine, depth of the cut, type of material, and slope of the cut area affect how quickly the pan is filled. When full, the pan is raised, the apron is closed, and the scraper transports its load to the fill area. There the pan height is set and the lip is opened (the lip is what the bottom edge of the apron is called), so ...
