Core Principles


Earthwork Services operators manually make sure that every high and low elevation point, ridge, swale, break line, hinge, top/bottom of wall and pad elevation is accounted for in our digital terrain model and is considered in the volumes calculations.

Fast Turnaround
Most projects are in and out of our shop within 48 hours after we receive the plans and CAD files. In some instances we can even provide same day turnaround. All volumes are emailed as a PDF as soon as they are available.

Most residential and commercial projects cost between $85-$500 (on average $300). The price includes a complete set of graphics, volumes, areas, a summary letter and area label map.

Earthwork Volumes

Earthwork Volumes Summary Letter

From your design you can receive the following information, which can be utilized in negotiating bids, settling engineering issues and verifying cost estimates.

We customarily address the following items in our Earthwork Volumes.

  • Stripping
  • Demolition
  • Strata Layers (such as rock)
  • Over-excavation and Back Fill
  • Pre-Load
  • Structural Fill
  • Phasing / Staging
  • Sub-Grades
  • Compaction
  • Balance Analysis

We can calculate volumes from hardcopy, electronic or hand drawn grading plans. We can build your grading plan from road centerline horizontal and vertical alignment and typical sections. We also have the ability to calculate volumes from plotted cross sections.

Volumes are sub-categorized and broken out for building pads, paving surfaces, ponds, and general landscaping to define varying material types such as structural and non structural fills. They can also be customized as per your directions to meet your specific needs.


A small sample of our graphics

Our reports can come with either booklet (8 1/2" X 11") or Poster size (24" X 36" or larger) graphics.

Our typical package includes:

We can also provide plotted cross sections and a 3D drive through of your site. Samples of our graphics can be seen on our sample graphics page.

A Rendering

We are now also offering advanced graphics options that include photo real renderings and photo manipulations. The sample page has links to galleries of example images.

GPS Models

GPS Models

Our years of experience building accurate digital terrain models makes the difference for you in dollars and time. We are an authorized model provider for Trimble and Terra model systems. We can create digital Terrain Models for Trimble grading control equipment created in Terra Model or in Agtek 3-D, AutoDesk Civil 3-D, and Advanced TIN Master DTM for use in most industry standard GPS machine control equipment such as Topcon, and Agtek.

Now available from AGTEK - Smart Dirt app (works with Android phones, tablets and iPhones)
You can attend pre-bid walk-thrus armed with the plan set in your pocket; geo-locate pad corners, grading limits and daylight lines; mark spoil piles; and initiate your takeoff on-site using SmartDirt’s measure mode. Email reports back to the office or save them to the cloud.

Expert Witness

We have extensive knowledge in earthwork and civil engineering software, earthwork calculation methods, as well as surveying, grading design, and earthwork construction. We are able to successfully defend our own calculations, and challenge opposing computer generated earthwork calculations.

We can analyze and often correct insufficient or bad data, inaccurate Tin models and quantity computations. We can prepare or challenge evidence, and provide expert witness testimony. We can show what went wrong, and be able to document and display findings, and provide resolution to most earthwork disputes.

We are comfortable both in meetings and courtrooms. Over the years, we have made, or in some cases saved, our clients millions of dollars in resolving earthwork related disputes.
