CAD MODELLING & DRAFTING SERVICES FOR SURVEY AND ENGINEERING COMPANIES

Survey companies and engineering firms send us raw data — field sketches, scanned PDFs, red-marked drawings, or outputs from total stations and laser scanners. We send back production-ready CAD drawings in DWG, DXF, DGN, or any format your project requires.

Fervent Technologies has delivered CAD drafting for infrastructure projects, piping layouts, structural detailing, architectural plans, and as-built documentation since 2011. Our team works in AutoCAD, MicroStation, Civil 3D, and AutoCAD Plant 3D — the same platforms your clients and contractors use. Standard turnaround is 48 hours. Complex drawing sets are quoted and scheduled upfront.

We convert any input — site sketches, scanned paper drawings, PDF redlines, or survey field data — into clean, accurate 2D CAD drawings ready for construction, planning, or handover.

What we produce:

  • Floor plans, elevations, sections, and reflected ceiling plans
  • Topographic and site layout drawings from survey data
  • Architectural and structural drawings to planning and building regulations standard
  • Mechanical, electrical, and plumbing (MEP) layout drawings
  • Piping general arrangement (GA) drawings and isometrics
  • P&ID and PFD drawings to ANSI/ISO standards
  • Fire protection layouts to NFPA codes
  • As-built drawings from site surveys and laser scan data
  • Paper to CAD conversion and legacy drawing digitisation
  • DGN to DWG migration (MicroStation to AutoCAD)

Formats delivered: DWG · DXF · DGN · PDF · georeferenced drawings where required

For projects requiring spatial accuracy before BIM is needed, we produce 3D CAD models directly in AutoCAD or Civil 3D — full geometry, accurate dimensions, and clean layer structure.

What we produce:

  • 3D architectural and structural models from 2D drawings or survey data
  • Terrain and site models from point cloud or total station data
  • Piping and equipment 3D layouts in AutoCAD Plant 3D
  • HVAC duct routing and spatial coordination models
  • SolidWorks 3D model conversion for mechanical components

Survey companies working on roads, rail, utilities, and site development projects need CAD deliverables that tie directly into the project coordinate system and comply with client standards.

What we produce:

  • Topographic drawing sets from field survey data (AutoCAD Civil 3D)
  • Road and corridor plans, long sections, and cross sections
  • Utility mapping and underground service layouts
  • Volume calculations and earthwork drawings
  • Network Rail, Highways England, and NFPA compliant drawing sets
  • Site layouts for planning applications and construction

Industrial and process plant projects require CAD deliverables that meet engineering standards and feed into downstream piping, structural, and fabrication workflows.

What we produce:

  • Piping layout drawings and isometrics (AutoCAD Plant 3D)
  • Equipment arrangement drawings
  • Structural steelwork detailing and connection drawings
  • HVAC and mechanical drawing sets
  • P&ID updates from as-built survey data
  • DWG deliverables compatible with AVEVA, SmartPlant, and Revit pipelines

Many survey and engineering companies hold years of drawings in outdated formats — scanned paper, PDF, old DGN files, or proprietary formats that don’t open in modern software.

What we convert:

  • Raster (scanned) drawings to intelligent vector CAD
  • PDF to DWG with correct layers, blocks, and annotation styles
  • MicroStation DGN to AutoCAD DWG
  • Paper drawings and hand sketches to CAD
  • Legacy software formats to AutoCAD or Revit
  • AUTOCAD 2024/2025
    • AUTOCAD LT
    • AUTOCAD CIVIL 3D
    • AUTOCAD PLANT 3D
    • MICROSTATION
    • AUTOCAD P&ID
    • SOLIDWORKS
    • REVIT (FOR CAD-TO-BIM CONVERSION)
  • AVEVA E3D
  • SMART PLANT 3D
  • HEXAGON TEKLA
  • QGIS (FOR GEOREFERENCED DRAWING OVERLAYS)

Have drawings that need converting, updating, or produced from scratch?

Send us your files, and we’ll confirm scope, timeline, and cost within 4 hours.
Or send us a sample drawing set — we’ll produce one sheet at no charge so you can see the quality before committing.
