Earthwork should be evaluated as early as practical, ideally during the inspection or due diligence period. This gives the land team an opportunity to understand potential cut/fill, import/export, grading assumptions, and other earthwork risks while there is still time to evaluate alternatives or adjust the development budget.

Yes, provided enough information exists to establish an existing-ground surface and reasonable proposed grading assumptions. Early earthwork analysis will not have the same certainty as an evaluation based on final engineering, but it can provide valuable budget and risk information before the design is complete.

A site plan or conceptual layout, geotechnical information, property location, and usable existing-ground topographic information are typically a good starting point. Earth Tek can review what is available, identify missing information, and determine what level of analysis can reasonably be performed.

A usable existing-ground surface is required, but a newly commissioned traditional topographic survey is not always required for an early-stage evaluation. Depending on the project and required level of accuracy, existing engineering data, appropriate GIS elevation information, or LiDAR may provide a usable existing-ground surface.

Yes. LiDAR can provide detailed existing-ground elevation information that can be used for earthwork analysis. Earth Tek has LiDAR drone capability in the Jacksonville region and access to a network for projects elsewhere in the United States. LiDAR collection is a separate scope and fee from the earthworkevaluation.

Accuracy depends on the quality and completeness of the information available. Early-stage analysis should not create false precision. Earth Tek identifies the assumptions behind the quantities and helps determine which unknowns could materially affect the earthwork budget as additional information becomes available.

Existing topography, proposed grading, pad elevations, stripping depths, compaction factors, unsuitable soils, rock, and import/export requirements can all materially affect earthwork quantities and cost. Understanding the assumptions behind these variables is often as important as the initial quantity itself.

Compaction assumptions affect how much excavated material is ultimately available for compacted fill. A change in the assumed compaction factor can materially change projected site balance and the amount ofmaterial that may need to be imported or exported.

Raw cut-and-fill quantities do not always represent the final site balance. Stripping, compaction, unsuitable material, rock, pad requirements, and other grading assumptions can change how much usable material is actually available. A site that initially appears balanced can therefore become an import site once those factors are considered.

Potentially. Changes to pad elevations or grading assumptions can affect cut/fill quantities, site balance, and import/export requirements. Evaluating alternative scenarios early can help determine whether a grading adjustment creates a meaningful earthwork opportunity before the design becomes more difficult to change.

Yes, when the available information supports the analysis. Earth Tek can model alternative assumptions and compare how changes affect quantities, site balance, and potential import/export exposure. This helps the project team understand the sensitivity of the earthwork budget before final engineering.

Depending on the project stage and available information, an Earth Tek evaluation can include 3D surface modeling, cut/fill quantities, site balance and import/export analysis, elevation heat mapping, review and documentation of key assumptions, scenario analysis, and identification of potential earthwork risks or opportunities. The emphasis is not simply producing another quantity; it is understanding what is driving the quantity.

A contractor's takeoff is often developed for pricing and construction. An independent evaluation gives the owner or developer another perspective focused on the quantities, assumptions, potential risks, and their effect on the development budget. The purpose is not to prove the contractor or engineer wrong. Sometimes the independent analysis confirms the assumptions being carried; other times it reveals something that deserves further evaluation.

Earthwork can represent a significant and variable portion of a development budget. An independent evaluation can help the land team understand the assumptions behind the earthwork number before relying on it for an acquisition decision. Confirmation can provide additional confidence, while a material difference can be investigated while options still exist.

Ideally, Earth Tek should be involved when a potential deal first enters the land team's evaluation process, not only after an earthwork problem is suspected. Sometimes the analysis confirms that the earthwork assumptions being carried are reasonable. Other times it reveals an assumption, risk, or opportunity that deserves additional attention. In either case, the land team has better information before making the nextdecision
