Myzox M-1500GP Mini Prism for As-Built Survey Malaysia

 

An as-built survey verifies the actual position of completed construction work against the intended design.

 

Surveyors may need to measure completed columns, walls, foundations, structural steel, drainage, utilities and other construction elements. Many of these points are located close to structures where positioning a conventional full-size prism can be inconvenient.

 

The Myzox M-1500GP 1.5-inch Mini Prism provides a compact reflector option for compatible total station measurements during as-built surveys in Malaysia.

 

Why Are As-Built Surveys Important?

 

Construction does not always match design coordinates exactly.

 

During an as-built survey, the survey team records the actual location of completed work so that it can be compared with:

 

Approved drawings

 

Design coordinates

 

Structural plans

 

Construction tolerances

 

Project specifications

 

BIM or CAD data

 

Existing site records

 

The results can help engineers and contractors identify deviations before subsequent work proceeds.

 

Why Use a Mini Prism?

 

As-built measurement often takes place after structures have already been constructed.

 

The survey point may therefore be:

 

Close to a concrete column

 

Beside a finished wall

 

Near a foundation edge

 

Around structural steel

 

Inside a restricted area

 

Near drainage structures

 

Around utilities

 

Close to machinery or equipment

 

A compact prism can make physical target placement easier in these situations.

 

Myzox M-1500GP Features

 

The M-1500GP uses a 1.5-inch / 38 mm prism and is designed as a compact surveying target.

 

Key features include:

 

38 mm / 1.5-inch mini prism

 

0 mm prism constant

 

Dual Lock mechanism

 

Screw Lock / Quick Lock

 

Wide tilting capability

 

Maximum tilting angle approximately 38°

 

Ø9 mm pole

 

Circular level

 

Removable prism cover

 

The combination of compact size and adjustable positioning makes it useful for various construction survey applications.

 

As-Built Column Survey

 

Column positions may need to be checked after construction.

 

The surveyor can measure selected points and compare the observed coordinates against the design.

 

A typical workflow is:

 

Establish Control → Set Up Total Station → Position Prism → Measure Column → Compare Coordinates

 

When the target point is close to the column itself, the compact dimensions of the M-1500GP can be advantageous.

 

Structural Steel As-Built Survey

 

Steel structures may require verification before subsequent installation work continues.

 

Possible checks include:

 

Steel column position

 

Base plate position

 

Structural alignment

 

Connection locations

 

Anchor bolt positions

 

Selected elevation points

 

A mini prism can provide a defined reflector target around structural elements where access is limited.

 

Drainage and Infrastructure As-Built Work

 

The same concept applies beyond buildings.

 

Mini prisms can also support selected as-built measurements for:

 

Drains

 

Culverts

 

Kerbs

 

Road structures

 

Utility installations

 

Manholes

 

Civil structures

 

Infrastructure projects

 

The appropriate reflector should always be selected according to the measurement distance, access and required accuracy.

 

Remember the 0mm Prism Constant

 

The M-1500GP has a 0 mm prism constant.

 

Before starting an as-built survey, confirm that the total station reflector settings correspond to the prism being used.

 

This is especially important when the survey team uses several reflectors during the same project.

 

For example:

 

Standard Prism → M-1500GP → Standard Prism

 

Do not assume the instrument configuration remains correct after changing the target.

 

Target Height Is Also Important

 

For coordinate and elevation measurements, incorrect target height can introduce errors into the final survey data.

 

Before recording important as-built points, check:

 

Prism Model → Prism Constant → Target Height → Target Level → Total Station Setup

 

Good field procedures are particularly important because errors discovered after leaving the site can require costly remeasurement.

 

Mini Prism vs Reflectorless for As-Built Survey

 

Modern total stations may also provide reflectorless measurement.

 

So why use a prism?

 

The two methods serve different situations.

 

Reflectorless

 

Useful when the physical point cannot easily be accessed.

 

Mini Prism

 

Useful when the surveyor can place a defined reflector target at the required location.

 

Professional survey teams may use both methods depending on site conditions and project requirements.

 

Suitable for Topcon Total Station Users

 

The M-1500GP can be considered for compatible reflector measurements with professional total station equipment.

 

For teams using Topcon total stations, the mini prism can complement the standard prism already carried in the survey kit.

 

MTM Precision can assist customers in selecting suitable prism accessories according to their total station and surveying application.
