ADSCivil Level

DESIGN AND VOLUME LEVELING

Leveling is a primary task in design and construction work. Normally, this task accounts for 15–20 % of the total investment of the project. There are some special cases of leveling up to 30% of the total investment. Therefore, the accurate calculation of the leveling volume is especially important.

ADSCivil Level, a specialized tool to support leveling design, elevation planning design and calculating the volume of excavation leveling. ADSCivil Level can be run independently or integrated with other software in the ADSCivil infrastructure design solution suite.

Not just a software for calculating the amount of excavation, backfilling, and leveling, ADSCivil Level provides a set of tools to support the design of the terrain surface after leveling (Design Model).

• Design of slope direction planning.
• Design of traffic intersection leveling.
• Design of slope by controlling the terminal elevation.

LEVELING DESIGN BY SQUARE GRID METHOD

The square grid method is the most basic method in the design, construction, and acceptance of leveling.

This method has many outstanding advantages:

• Fast calculation, easy to do manually or by computer software.
• Clearly displayed results, easy to check on drawings.
• Well meet the requirements of the construction process and acceptance on the site.

The traditional square grid method has many problems with its high errors if encountering special cases with multilevel terrain. To increase accuracy, it is necessary to divide the grid into many small grids or split the grid cells into small sizes. Both options above have certain obstacles in the implementation of drawings.

However, with many outstanding advantages compared to other methods, the square grid method is still the most commonly applied and standardized, becoming a mandatory requirement in design regulations, construction, and acceptance of ground leveling.

To reduce errors in the calculation methods, ADSCivil Level offers a revolutionary solution that allows users to adjust the size of grid cells on the plan. The calculated grid cells will be able to adjust the thickness in different positions to keep up with the change in the design surface. As a result, ADSCivil Level will eliminate the errors encountered by the square grid method but will not break the generality of the method while it still ensures the exported drawing according to current standards.

VERIFY LEVELING VOLUME USING THE 3D SOLID METHOD

• The square grid method is based on the integral calculation of grid cells that are roughly rounded to a vertical prism. Each grid position or each way of sizing grid cells will give a different calculation result. Thus, which position will be the correct one to set the grid?
• The 3D solid method provides 3D real volume results between the existing and the post-leveling surface. It always gives an accurate result regardless of the grid position and the size of the grid cells. This method completely eliminates the errors encountered when calculating by the square grid method.
• The calculation results of the 3D Solid method are a possible basis for comparing, evaluating, and adjusting the position and meshing of a square grid to get the most accurate results. Usually, the designer uses the 3D solid method to calculate the exact leveling volume, then gradually tries a few times the position of the grid and will find the most optimum position to calculate.

LEVELING CALCULATION BY STAGE

The ground leveling problem in practice is not simply leveling once but many times from the current surface to the design surface. Thus, the leveling volume can be calculated by many different leveling stages. Actually, some common cases can occur in leveling work:

• Case 1: The unsuitable soil layer in the embankment is removed, then the new and stable materials are filled to the design surface.
• Case 2: The volume of ground leveling is large, so it is necessary to separate into several stages of the leveling construction.

CALCULATION OF SIDE SLOPE LEVELING

The volume of side slope earthworks accounts for a fairly large part of the leveling work, especially in some cases, up to 50% of the total earthwork volume. Therefore, ADSCivil Level supports the design and detailed volume of the side slope leveling to ensure the most accurate and complete results:

• Designing a customizable terrace for a high embankment and deep excavation.
• Controlling the limit of the ground leveling boundary.
• Applying a retaining wall for a negative side slope.
• Drawing a cross-section of the leveling side slope.
