Industrial Construction and Dimensional Control Survey Office Technician

An individual with experience, skills, and knowledge earned while working on medium and/or large-scale industrial construction projects. The position requires strong technical skills, attention to detail, and the ability to manage multiple requests in a fast-paced environment.

This position is heavily intensive on data calculation and processing, and report delivery in a quick and efficient manner supporting all construction and fabrication activities on location.

This position focuses on processing and managing field survey data, preparing construction layout information, performing quality control checks, maintaining accurate project records, and producing survey deliverables.

The technician will work closely with field survey crews, office personnel, and project management to ensure that survey information is accurate, organized, and delivered efficiently to support construction activities.

RESPONSIBILITIES:

Field Data

• Download, organize, and process daily survey data collected by field crews.
• Process conventional survey observations, including total station measurements, control observations, and construction as-built data.
• Review field survey data for completeness, accuracy, and consistency.
• Identify potential errors, discrepancies, or missing information in field data.
• Perform coordinate calculations, transformations, and conversions as required.
• Communicate with field crews to resolve data discrepancies or missing information.

Survey Quality Assurance and Quality Control (QA/QC)

• Perform initial QA/QC reviews of processed survey data and deliverables.
• Verify raw observation data against point cloud data and 3D design models and verify field notes and pictures to ensure data was captured in a consistent method.
• Compare as-built survey information against design drawings, models, and specified tolerances.
• Check total station setup residuals, control ties and any warnings or errors, combined with checking for consistency and coherence with previous surveys.
• Review survey calculations for potential errors.
• Maintain traceability between original field observations, calculations, and final deliverables.

Calculations

• Utilizing client-provided design drawings, PDFs, files and data to calculate design coordinate values for:
• Anchor bolts, concrete piers, walls and pads, other foundations.
• Centerline, steel elevations, piping and flanges for Pharmaceutical Process Equipment (Tanks/Pumps/Skids/Chillers/Boilers and electrical equipment etc.)
• Steel structures such as cooling towers, cable racks, stick built foundations, platforms and skids
• Piping/flanges, nozzles and CIP/IP points for modules
• Underground pipe and fixtures horizontal, vertical and slope design information
• Floor penetration/core hole horizontal and vertical design location
• And much more
• Verify calculations or given values from AutoCAD drawings or 3D models against IFC PDF reports
• Derive and calculate verticality/plumbness of Tanks, Structures and Steel from field survey measurements and laser scan data, calculate tolerances and create reports
• Use dimensional control survey software to calculate:
• Least squares 2D and 3D circle fits from survey data of pipes and cylinders
• Least squares 2D and 3D line fits
• Best fit planes and associated normal vector
• Flange bolt hoe rotation flange face angles and centerline
• Complex Weighted and Non-Weighted Least Squares 2D and 3D Best-Fit Transformations to fit equipment and modules into design positions based on critical interface points
• Intersections of multiple lines in different planes
• Complex 3D and 2D rotations and alignments
• Radius reductions or additions of circle fits based on ball prism offsets
• Use AutoCAD, Civil 3D and Trimble Business Center to calculate and interpolate coordinates and values
• Use point cloud data or extract data from point clouds to:
• Model and create 3D centerlines of pipe and flanges
• Generate Heat Maps of concrete floor surfaces against design values to determine adherence to specification and slope
• Extract point data from equipment and tanks to supplement conventional survey data
• Perform QA/QC on survey measurements to ensure they line up with physical point cloud
• Register or Best-Fit point clouds to desired locations
• Perform control checks, redundant observation checks and control networks adjustments in TBC

Analysis, Reporting and Deliverables:

• Create survey reports in the formats of Point Clouds, Coordinates, Marked up PDFs, CAD drawings, Excel Spreadsheets and CAD drawing files
• Analyze as-built survey information against design and report on deltas and Out Of Tolerances
• Assist with dimensional verification of structural, mechanical, and equipment installations.
• Communicate potential issues or discrepancies to field crews and office leadership.
