Myzox Monitoring Prism for High-Rise Building Construction Monitoring

 

High-rise construction projects may require repeated surveying observations to monitor selected points on the new structure, nearby buildings, retaining systems and other surrounding structures.

 

The Myzox TK-10S / TK-10 Monitoring Prism L-Bar Type provides a compact fixed target for total station observations and is suitable for high-rise building construction and structural movement monitoring in Malaysia.

 

Once installed at predetermined monitoring points, the prism can remain in position for repeated measurements throughout different construction stages.

Why Monitor High-Rise Construction Projects?

 

Large building projects often involve multiple phases of work, including:

 

Piling

 

Foundation construction

 

Deep excavation

 

Basement construction

 

Retaining structures

 

Structural construction

 

Adjacent infrastructure works

 

In developed areas, these activities may also take place close to existing buildings and infrastructure.

 

Depending on project requirements, monitoring can provide positional information for selected points throughout the construction period.

 

What Can Be Monitored?

 

A total station and fixed prism network can support observations of selected locations such as:

 

Existing neighbouring buildings

 

Retaining walls

 

Excavation support structures

 

Structural columns

 

Building façades

 

Perimeter structures

 

Adjacent infrastructure

 

Other designated monitoring points

 

The monitoring locations should be selected according to the project's surveying and engineering requirements.

 

How Does Myzox Monitoring Prism Work?

 

The Myzox monitoring prism is securely installed at a selected location.

 

A total station measures horizontal angle, vertical angle and distance to the prism.

 

These observations can be used to determine the target position.

 

The process is then repeated throughout construction:

 

Install Prism → Baseline Survey → Construction Begins → Repeat Measurements → Compare Coordinates → Evaluate Positional Changes

 

Because the prism remains fixed, each observation refers to the same physical monitoring point.

 

Monitoring Neighbouring Buildings

 

One important application for high-rise projects is monitoring existing buildings close to the construction site.

 

Monitoring prisms may be installed at selected points before major works begin.

 

Baseline measurements can then be collected.

 

During construction, the survey team repeatedly observes the same targets.

 

This may be particularly relevant during:

 

Piling

 

Deep excavation

 

Basement works

 

Foundation construction

 

Major structural stages

 

The resulting survey data provides a history of the measured positions.

 

Deep Excavation for High-Rise Buildings

 

Many high-rise projects include multiple basement levels.

 

Deep excavation can therefore become an important stage of the monitoring program.

 

A typical monitoring sequence could be:

 

Pre-Construction Baseline

↓

Piling Works

↓

Excavation Stage 1

↓

Excavation Stage 2

↓

Excavation Stage 3

↓

Final Excavation Level

↓

Basement Construction

↓

Superstructure

 

Fixed monitoring prisms allow the same selected targets to remain part of the survey network throughout these stages.

 

Retaining Wall Monitoring

 

Retaining systems around a high-rise excavation may require multiple monitoring points.

 

For example:

 

MP01 — MP02 — MP03 — MP04 — MP05 — MP06

 

Each monitoring prism provides a defined target.

 

Repeated observations allow the project team to compare measured positions at different sections of the retaining structure.

The compact configuration helps establish fixed prism points where a conventional prism pole or large prism assembly would be inconvenient.

 

Why Is the L-Bar Design Useful?

 

Monitoring points often need to be installed directly on structural surfaces.

 

The L-bar configuration provides a compact mounting arrangement for fixed monitoring applications.

 

This is different from a standard survey prism setup, where the target is normally mounted on a portable prism pole.

 

For high-rise monitoring, a fixed target can remain available for repeated observations without requiring personnel to access the target during every survey cycle.

 

X/Y Direction Adjustment

 

High-rise construction sites can present challenging observation geometry.

 

The monitoring prism may be installed on a wall or structure that does not directly face the total station.

 

The Myzox TK-10S / TK-10 provides X/Y directional adjustment, allowing the prism orientation to be adjusted during installation.

 

This helps establish a suitable line of sight toward the intended observation position.

 

Why High Visibility Can Be Useful

 

Construction sites contain many structural and temporary elements.

 

A clearly identifiable monitoring target can make field observation and target management easier.

 

The TK-10S high-visibility configuration can be particularly useful where survey teams need to identify installed monitoring points among surrounding site features.

 

Clear monitoring point IDs and photographic records should also be maintained.

 

Monitoring Horizontal Displacement

 

Total station observations can provide coordinate information for each fixed target.

 

Comparing coordinates between observation periods can help identify changes in horizontal position.

 

For example:

 

Baseline X/Y → Current X/Y → Coordinate Difference

 

Multiple monitoring points can provide information about positional changes across different areas of the structure.

 

Monitoring Vertical Displacement

 

Depending on the survey methodology and required accuracy, total station observations may also provide elevation information.

 

Changes in measured elevation can be compared across observation periods.

 

For projects requiring dedicated high-precision settlement monitoring, precise levelling or other appropriate monitoring methods may also be specified.

 

Monitoring New and Existing Structures Together

 

A large construction project may involve monitoring more than one type of structure.

 

For example:

 

Existing Building A

→ Monitoring Prisms

 

Existing Building B

→ Monitoring Prisms

 

Retaining Wall

→ Monitoring Prisms

 

New Structure

→ Monitoring Points

 

This creates a broader monitoring network around the project.

 

The design of that network should be established by the responsible professionals.

 

Importance of Stable Reference Control

 

Fixed monitoring targets are only useful when measured against suitable survey control.

 

Stable reference points should therefore form part of the monitoring network.

 

A simplified system is:

 

Stable Reference Network → Total Station → Myzox Monitoring Prisms

 

If reference points are unstable, the interpretation of apparent movement at the monitored targets may be affected.

 

Prism Constant for Monitoring Work

 

The Myzox TK-10S / TK-10 has a specified prism constant of -25 mm.

 

The correct setting should be configured in the total station according to the instrument manufacturer's instructions.

 

For repeated monitoring surveys, maintaining consistent prism settings between measurement campaigns is important.

 

Manual Monitoring or Automated Monitoring?

 

Fixed prisms can support different monitoring workflows.

 

Manual Monitoring

 

Surveyors visit the project at scheduled intervals and observe the installed targets using a total station.

 

Automated Monitoring

 

Suitable specialized total station systems may repeatedly observe predetermined monitoring targets and process measurements using monitoring software.

 

The appropriate approach depends on project scale, monitoring frequency, equipment and engineering requirements.

 

Protect Monitoring Points Throughout Construction

 

Construction sites change rapidly.

 

Monitoring targets can potentially be affected by:

 

Scaffolding

 

Formwork

 

Cranes

 

Machinery

 

Temporary walls

 

Hoarding

 

New structural elements

 

Accidental impact

 

Monitoring points should therefore be inspected regularly.

 

If a prism is disturbed, removed or repositioned, the monitoring team should follow the project's procedure before comparing new measurements with the original baseline.

 

Total Station Calibration for Construction Monitoring

 

High-rise monitoring depends on consistent survey measurements.

 

Surveying instruments should therefore be properly maintained and checked according to professional requirements.
