3-D Laser Scanning / Modeling

PMI Scanning and modeling

3D laser scanning. High Definition Surveying. Reality Capture. By whatever name, it’s the state of the art in applying the latest technologies to map the physical world around us. Precision Measurements has been providing high quality scanning data and information to our clients since the days of the Cyrax 2500. That tradition continues today, utilizing the latest hardware and software technology from manufacturers such as Leica Geosystems, Autodesk, and more.

Whether working in Civil 3D, Revit, AutoCAD, ArcGIS, ArchiCAD, 3ds Max, Rhino 3D, Sketch Up, or SolidWorks. Whether the application is Engineering, Architecture, BIM, GIS, Entertainment, or Heritage. We live in a 3D world; we build in a 3D world. Today, we design in a 3D world. PMI uses Reality Capture tools to map existing conditions to a stunning level of detail, providing our clients with the most complete, most accurate information to form the basis of their design and decision making.

The raw dataset is a point cloud – a digital cloud of three-dimensionally accurate points representing any physical environment. From roads and bridges, to plants and utility systems, to cars, boats, and buildings – inside and out! Beyond the inherent value in more comprehensive, higher accuracy information, Reality Capture brings other benefits to the table. Safety: our field staff is able to collect high quality data while remaining out of harm’s way – less risk for both PMI and the client. Speed: more data can be collected more quickly – less downtime and greater efficiency. PMI works with each client to determine their deliverable needs – from raw point cloud data, to simple linework, to fully rendered 3D models.

Precision Layout in a Controlled Environment

PMI uses the industries most precise survey instruments to direct the placement of semiconductor producing systems. This machinery (tools) must be set to exact specifications due to the use of overhead automated delivery systems that transfers products throughout the different manufacturing areas.


Allowable tolerances for overhead automated delivery systems interaction with a tool's Load Port is approximately +/- 5 mm

Advantages of Using PMI

  • PMI's specialized teams have the ability to work hand in hand with everyone involved with the placement of the tools from designers and engineers to millwrights and tool vendors.
  • Customers can rest assured that each multi-million dollar "tool" is in the proper location, having to relocate a tool is "time and money" and some tools cannot be relocated after installation.
  • While our survey personnel are on-site, we are able to provide other services that may arise. An example of this may be to provide typical construction staking outside of the clean room for items that may arise from the base build.
  • Areas of concern within the clean room environment may be to align a part horizontally and vertically inside a tool in order for the tool owner to complete work on a damaged tool.


  • PMI can provide the customer with exact coordinates of the location of each tool that has been installed in hard copy form or in a digital format.
  • At each stage of tool setting our experienced survey team is there on location to give instructions as placement of the tool.
  • Through experience, PMI has found that an initial set needs to be followed up with a final location due to movement at the tool is assembled.

Hydrographic Surveys

PMI is one of the few firms that can offer full service Hydrographic Surveying services utilizing fully digital equipment.

PMI has three hydrographic vessels to perform its surveys. The first is a semi-enclosed 23’ boat. The other two are smaller, open skiffs. This allows PMI the versatility to perform surveys in shallow water. In addition to the vessels listed above, PMI also utilizes a proprietarily designed robotic vessel, incorporating a single beam echo-sounder and RTK GPS system, for accessing extremely shallow areas.

On-board these vessels PMI utilizes a range of electronic systems to provide extremely accurate horizontal and vertical data. PMI utilizes Odum, Innerspace, and Seafloor System depth sounding equipment in conjunction with RTK GPS.

PMI holds multiple Annual Service Contracts from various Districts of the Army Corps of Engineers. As such, PMI follows the operational procedures outlined in the Corps of Engineers Hydrographic Survey Manual. PMI also follows the procedures outlined in the Corps Manual for its quality assurance program.
