Our Services

Quality Assurance (QA)


A List of details help us to generate Pipe Material Specificatiion

Comparison with Point Cloud

Verify the model using As-Built Point Cloud Data

Comparison with Documents

We thoroughly examine the documents such as P&IDs, Site Plan, Equipment, and Structure

Clash Detection

Run a Clash Detection between Struct vs Pipe, Pipe vs Equipment

Hard to Follow As Built

Old & Running Plant have allot of issues, so sometimes it is impossible to follow as built condition

Comparison with Point Cloud & Documents

To ensure the accuracy of our isometric model, a comprehensive QA process is essential in identifying and eliminating any errors or faults made by the modelers. At Zareen 3D Surveys, our QA system is designed to be user-friendly and efficient.

Few Steps to Follow

To maintain the quality of our model after the QA process, we follow a set of steps that guarantee its reliability.
Firstly, we collect all the necessary documents from the client and create a list and table containing all the details to help us generate PMS and 3D modeling requirements.
We then verify the model using As-Built Point Cloud Data.
Next, we thoroughly examine the documents such as P&IDs, Site Plan, Equipment, and Structure. By comparing the P&ID with the site, we highlight and include the new modifications in the P&ID. Then, we release a revised version of that P&ID.
We run a Clash Detection check.
Installing a new plant is easy and has very few chances of errors. However, old and running plants have several issues. It is sometimes impossible to follow the as-built condition. Therefore, Zareen 3D Survey has a designer who can activate a professional solution for you. With the help of our designer, our quality assurance process is brilliant

Documents Control System

With our advanced technology, we can provide detailed drawings of every part of your plant. In addition, our company boasts the best document control system, with a portal that allows us to navigate, investigate, and review every detail of your documents

Latest Projects

Collombey Switzer-land

More Info

We have completed a plant Modeling for Collombey. It was a quite big project which been modeled in 13 Months with the help of our great software’s & great teams.The client fully satisfied from our 3D intelligent model. We have generated Isometric drawing for them so they can use after relocation. Also we did match marking for them. Also our UK team the one who did scanning over there. We took 56 days to finish to whole scanning. we have completed the project with high quality & committed time.


More Info

Our team just completed an As-built Plant Modelling Project for the Engro plant. The project involved creating isometric drawings,equipment and piping plans, structural plans, electrical and instrumentation plans, material take-off, piping support details, a PMS pipe material specification chart/table, and various reports per the client’s requirements.

Jebeli Ali Plant-Dubai

More Info

In today’s age, plant modelling has become increasingly necessary. If you want to modify, you need an exact plant model perfectly aligned with geo-referencing. Accuracy is crucial when modelling on-site or on a computer. To ensure accuracy, we installed a large plant geo-referenced control monument along the road and covered each block with four controls to prevent the model from moving or rotating. Our client required the same as a previous project, an as-built 3D intelligent model, and we are experts in this field. Our client was satisfied with our work.
