ENGINEERING DATASET

Solar Heating Engineering Company

Approximately 4 TB of Portuguese-language engineering and business records from a Brazilian solar heating company with 15+ years of operations and over 1,000 projects.

Company Profile

This collection comes from an anonymized Brazilian solar heating engineering company with more than 15 years of operations, over 1,000 delivered projects, and a peak workforce of more than 100 employees. Its records are primarily in Portuguese.

The company develops solar water heating systems for homes and commercial sites, including bathing and pool heating. Its work spans equipment, system design, installation planning, and engineering tailored to each project.

Full Dataset

At approximately 4 TB, the collection brings together technical project files and the records behind the business. It spans engineering, legal, commercial, finance, and sales divisions, along with communications. This breadth gives the engineering work useful context, from design and planning to the documents and exchanges around project delivery.

File Formats

The full collection contains 880k+ files across 1,300+ extension labels. The format mix shows the scale of the design work and the documents, messages, and media around it. Each lower bound below counts only the named formats and is rounded down.

  • 50k+ CAD drawings across .dwg and .dxf, with .dwl and .dwl2 working files also present.
  • 9k+ mechanical design files in .ipt, .iam, .idw, and .sldprt.
  • 3k+ building and 3D model files in .skp, .skb, .ifc, .rvt, .stp, and .igs.
  • 340k+ documents and presentations in .pdf, .txt, .docx, .doc, .ppt, and .pptx.
  • 45k+ spreadsheets and data tables in .xlsm, .xlsx, .xls, .xlt, and .csv.
  • 20k+ saved emails in .msg and .eml, mostly .msg in the full collection.
  • 300k+ photos and videos in .jpg, .jpeg, .png, .gif, .tiff, and .mp4.
  • 5k+ design graphics in .cdr, .ai, and .psd.
  • 65k+ archives and support files in .db, .bak, .log, .zip, and .rar.

Software and Workflows

The formats point to a mix of engineering design, project coordination, and business operations:

  • Drafting and building design: .dwg and .dxf support CAD workflows. .dwl and .dwl2 are associated with AutoCAD drawing sessions. .ifc and .rvt add building model and Revit project files.
  • Mechanical and 3D design: .ipt, .iam, and .idw are Autodesk Inventor parts, assemblies, and drawings. .skp and .skb are SketchUp models and backups. .sldprt is a SOLIDWORKS part format, while .stp and .igs support exchange between 3D tools.
  • Project and business work: Word, Excel, and PowerPoint formats sit alongside saved messages in Outlook's .msg format. .cdr is a CorelDRAW format, with .ai and .psd adding Illustrator and Photoshop file types.
