Myzox CL-28 CL-36 Auto Level for Earthwork Cut and Fill Leveling Malaysia
Myzox CL-28 CL-36 Auto Level for Earthwork Cut and Fill Leveling Malaysia
Earthwork is one of the earliest and most important stages of many construction and civil engineering projects. Before foundations, roads, drains or structures can be built, the site often needs to be excavated, filled and brought to the required formation elevation.
The Myzox CL-28 and CL-36 Auto Levels can be used for elevation checking during earthwork, excavation, cut-and-fill and site formation work.
The Myzox CL-28 provides 28X magnification with ±2.0 mm accuracy for 1 km double-run leveling, while the Myzox CL-36 provides higher 36X magnification with ±1.0 mm accuracy.

What Is Cut and Fill in Construction?
Cut and fill is the process of reshaping existing ground to achieve the required project elevation.
Cut means material needs to be excavated because the existing ground is higher than the required level.
Fill means additional material is required because the existing ground is lower than the required level.
Accurate elevation measurements help site teams determine whether a particular location requires additional cutting or filling.
Why Use an Auto Level for Earthwork?
An automatic level provides a practical method of comparing ground elevations against a known benchmark.
It can assist contractors during:
Existing ground level checks
Excavation
Filling
Site grading
Formation preparation
Road earthworks
Building platform preparation
Embankment construction
Drainage excavation
Regular level checking allows the site team to compare actual elevations with design elevations as earthwork progresses.
Checking Existing Ground Level
Before major earthwork begins, the existing ground elevation may need to be established.
A benchmark with a known elevation provides the reference.
The auto level and leveling staff can then be used to obtain readings at selected locations.
These readings can help engineers and contractors understand the elevation differences across the working area.
For detailed volume calculations, appropriate surveying methods and software may also be required.
Checking Excavation Depth
Over-excavation can result in additional work, material and cost.
Under-excavation means the site has not yet reached the required formation elevation.
The Myzox CL series can assist site teams in checking excavation levels against established reference elevations.
Applications may include:
Foundation excavation
Road excavation
Drain excavation
Building platform preparation
Utility trench work
Checking Fill Levels
Fill material is often placed and compacted in stages.
Elevation checks can be performed during the process to determine whether the site is approaching the required level.
This can help reduce the risk of placing unnecessary additional fill or stopping before the design elevation has been achieved.
Compaction quality itself requires appropriate compaction testing methods; an auto level is used for elevation control rather than soil density measurement.
What Is Formation Level?
Formation level generally refers to a prepared elevation upon which subsequent construction layers or structures will be built.
Depending on the project, formation may relate to:
Road construction
Building platforms
Foundations
Pavements
Infrastructure
Drainage works
Checking the formation level before subsequent work begins can help prevent elevation errors from being carried into later construction stages.
Myzox CL-28 for General Earthwork
The Myzox CL-28 provides:
Magnification: 28X
Objective Aperture: 36 mm
Minimum Focusing Distance: 0.4 m
1 km Double-Run Leveling Accuracy: ±2.0 mm
Self-Leveling Range: ±15′
Horizontal Circle: 360°
Weight: Approximately 1.3 kg
It can be considered for routine construction earthwork, building platform preparation and general civil engineering applications.
Myzox CL-36 for Larger Earthwork Projects
The Myzox CL-36 provides:
Magnification: 36X
Objective Aperture: 36 mm
Minimum Focusing Distance: 0.4 m
1 km Double-Run Leveling Accuracy: ±1.0 mm
Self-Leveling Range: ±15′
Horizontal Circle: 360°
Weight: Approximately 1.3 kg
Its higher magnification and specified leveling accuracy make it particularly attractive for larger civil engineering, road and infrastructure projects.
Auto Level for Road Earthwork
Road projects often require substantial cut-and-fill operations before pavement construction can begin.
An auto level can assist with checking:
Existing ground elevation
Excavation level
Embankment elevation
Formation level
Drainage elevation
Road-related reference levels
For larger road projects where observation distances may be longer, the CL-36's 36X magnification may provide an advantage.
Auto Level for Building Platform Preparation
Before foundation work begins, a development site may need to be brought to a specified platform level.
The Myzox CL-28 or CL-36 can assist contractors in checking elevations at multiple points across the site.
This can help identify:
High areas requiring additional excavation
Low areas requiring fill
Areas approaching the target elevation
Locations requiring final adjustment
Can an Auto Level Calculate Cut-and-Fill Volume?
Not by itself.
An optical auto level provides staff readings that can be used to determine elevations.
Calculating earthwork volume generally requires additional information such as:
Existing ground elevations
Design elevations
Horizontal positions
Site dimensions
Appropriate calculation method or software
The auto level therefore provides important elevation data but does not automatically calculate earthwork volume.
Auto Level vs Rotating Laser for Earthwork
Both instruments can be useful, but they work differently.
An optical auto level requires an operator to observe a leveling staff through the telescope.
A rotating laser creates a reference laser plane that can be detected using a suitable receiver.
An auto level remains a practical choice when optical leveling and traditional staff observations are preferred.
The best solution depends on the site, number of workers, working distance and measurement requirements.
Common Earthwork Leveling Mistakes
Using the Wrong Benchmark
All subsequent elevations can be affected if the starting benchmark is incorrect.
Staff Not Vertical
A tilted leveling staff can introduce reading errors.
Tripod Movement
Soft or recently filled ground can cause tripod legs to move or settle.
Incorrect Recording
A field reading that is written incorrectly can result in an incorrect calculated elevation.
Not Rechecking Important Points
Critical formation levels should be verified according to the project's quality-control procedures.
Frequently Asked Questions
Can the Myzox CL-28 be used for earthwork?
Yes. The CL-28 can be used for general elevation checks during excavation, filling and site formation work.
Is the Myzox CL-36 suitable for road earthworks?
Yes. Its 36X magnification and ±1.0 mm leveling specification make it suitable for many larger civil engineering applications.
Can an auto level measure excavation depth?
It can be used to determine elevations before and during excavation, allowing the difference in level to be calculated.
Can I use an auto level for cut and fill?
Yes. Elevation measurements can help determine whether specific locations are above or below the required design level.
Does an auto level measure soil compaction?
No. An auto level measures elevation differences. Soil compaction requires appropriate density or compaction testing equipment.
Which model should I choose for earthwork?
For general construction earthwork, the CL-28 can be sufficient. For larger sites, longer observation distances or higher accuracy requirements, consider the CL-36.
