Excavation – Earthwork Quantity Takeoffs NYC

What is earthwork in excavation?

Before the earthwork is started, the whole area where the work is to be done shall be cleared of grass, roots of trees and other organic matter. Site preparation shall consist of clearing grubbing and removal of any and all inappropriate materials.
A common method of classifying excavation is by type of excavated material: topsoil, earth, rock, muck, and unclassified.

We provide earthwork takeoffs for busy contractors. We build earthwork takeoff models using the most advanced software in the industry. Taking two dimensional plans, or AutoCAD software files we turn them into a three-dimensional earthwork takeoff model using AGTEK software. Using these models, we generate valuable data using our software that can be used for bidding and estimating projects. The dirt work takeoff compares the existing topography with the proposed design/subgrade and outputs precise cut and fill estimates.  These reports are designed for general contractors, owners, architects, developers, home builders, engineers and subcontractors.

We provide our services for general and sub-contractors as well as owners, developers, asset managers, architects and engineers. Each estimator specializes in specific trades, resulting in the most up to date and specialized knowledge in their area. With this specialization comes the capacity to tailor any needs for your project. Our team has performed estimates for all trades on new construction and renovations for high rise residential & office buildings, hospitals, warehouses, transit hubs, restaurants and single family homes.

Our team specializes in picking up every high and low elevation point, ridge lines, top and toe of slopes and break lines. Most projects leave our shop in one to three days. Rush turn around available upon request and based on schedule demands.

Our construction material take-off reports can be used to figure rock, clay, import, export, areas of interest, excavation, grading, stored materials and balancing sites. In addition to dirt work estimates we can figure asphalt, concrete, building pads, curb/gutter, gravel, cement, landscaping and planting. The volumes report categorizes and breaks out areas separately for design/sub-grade and existing/demolition surfaces.

How is earthwork quantity calculated?

Area of Cutting and Filling is found out for each Section with Trapezoidal Method or Nett Area Calculation Method. Then volume is determined by multiplying Average Area with Distance between Sections.

How do you calculate excavation footing?

Volume of excavation
  1. =4.60 Mtr.
  2. =0.30 Mtr. + 3.00 Mtr. …
  3. =3.60 Mtr.
  4. Total Volume of excavation. = 4.60 Mtr x 3.60 Mtr. …
  5. = 49.68 CUM.
  6. Volume of backfilling. = Volume of excavation – Volume of concrete.
  7. Backfilling is done after the construction of PCC, footings, columns. …
  8. Volume of pcc.

What is Type D excavation?

201.11. 02 Type D – Common – Common material is all other excavation materials of a nature not included in the foregoing description of Type A, regardless of the nature or condition of the material, or the method used to excavate or remove.

  • 3.1 Cut and fill excavation.
  • 3.2 Trench excavation.
  • 3.3 Basement excavation.
  • 3.4 Road excavation.
  • 3.5 Bridge excavation.

What excavation equipment might be necessary for your project?

  • Backhoe loader. These have an adjustable shovel in the front and a bucket in the back. …

What is a deep excavation?

Shallow excavations are defined as being anything less than 1.5 metres deep, which really is not very deep at all; a relatively short person could comfortably see over the top. Deep excavations, on the other hand, are defined as being any excavation which is more than 4.5 metres in depth – a considerable height indeed.

What is benching in excavation?

Benching (Benching system)” means a method of protecting employees from cave-ins by excavating the sides of an excavation to form one or a series of horizontal levels or steps, usually with vertical or near-vertical surfaces between levels.
We assist Contractors, Developers, Civil Engineers at any stage of a project to determine the most efficient way to deal with site grading. We provide practical “What if” scenarios and solutions for any sized project, which reduces risk, project costs and overall design time.
