AutoCAD
The drawing environment behind every deliverable.
Plan-and-profile, construction packages and redline revisions are produced natively in AutoCAD, to your layering, blocks and title-block standard.
Utility Distribution Drafting & Engineering Design
Utility distribution drafting,designed with precision.
AutoCAD, GIS, landbase and SPIDAcalc production for electrical, telecom and fibre distribution — delivered overnight to your standard, ready for your professional’s seal.
What we design
Utility distribution drafting and engineering design.
01
Distribution drafting
Construction drawings for overhead and underground distribution, drafted to your utility standard.
- Pole layouts and framing details
- Overhead and underground distribution
- Construction-ready drawing sets
- Standards-compliant utility drafting
02
AutoCAD design
Detailed engineering drawings produced natively in AutoCAD, to your CAD standard.
- Plan-and-profile drawings
- Redline updates and drawing revisions
- Construction packages and sheet sets
- Layering, blocks and title blocks to your standard
03
GIS & landbase integration
Survey-accurate landbase and spatial data, so every drawing sits on a true base.
- Landbase drafting and maintenance
- Property boundaries and road alignment
- Existing utility asset capture
- GIS integration and spatial accuracy
04
SPIDAcalc engineering
Pole loading analysis and structural verification, with an engineering report per structure.
- Pole loading and structural verification
- Attachment and wind loading cases
- Safety-factor and capacity assessment
- Engineering reports per structure
05
Telecom & fibre design
Fibre routing and pole-attachment design for communication and joint-use networks.
- Fibre routes and network expansion
- Pole attachment layouts
- Joint-use design and coordination
- Communication infrastructure drafting
How we work
One package,
five stages.
01 — AUTOCAD
Construction linework drafted to your CAD standard — layers, blocks and title block.
02 — GIS
Asset and network data reconciled from GIS into a coordinate-true base.
03 — LANDBASE
Property lines, road and right-of-way resolved into one survey-true base.
04 — SPIDACALC
Every structure verified for pole loading — a pass, or a buildable make-ready.
05 — FINAL DRAWING PACKAGE
Sheets, calculations and an assumption log — sealed-ready, delivered on schedule.

Why Spanex
Precision, checked before it ships.
Engineering accuracy
Drawings are checked against standards and analysis before release, not after.
Utility experience
We work only in utility distribution — electrical, telecom and fibre.
Fast turnaround
Scoped schedules with overnight production, so review starts when your day does.
Scalable support
Add or reduce drafting capacity by the project, without hiring.
Quality control
An independent reviewer checks every package before it ships.
Standards compliance
Your CAD standard and the governing code drive every sheet.
Reliable documentation
Assumption logs, revision history and transmittals travel with the work.
Modern workflows
AutoCAD, GIS and SPIDAcalc in one coordinated, version-controlled pipeline.
The network
Every line we draw ends up on a real structure.
Pole framing, guying and conductor — we design to what actually gets built, and to the code that governs it.
Worked to your standards
We hold to the code you name, not one of our own.
- CSA C22.3 No. 1Overhead systemsLoad cases and clearance requirements for overhead distribution.
- CSA C22.3 No. 7Underground systemsApplied where the package includes underground distribution.
- O. Reg. 22/04Ontario electrical safetyContext for work on Ontario distribution assets.
- Distributor standardsConstruction & attachmentYour utility's construction standard and attachment guidelines govern.
- SPIDAcalcStructural analysisModelled to your client file, load cases and pass/fail thresholds.
- Your CAD standardDraftingLayering, blocks, xrefs and title blocks follow your template.
About
Spanex Engineering provides utility distribution drafting and engineering design support for electrical, telecom and fibre distribution networks.
We work in AutoCAD, GIS, landbase and SPIDAcalc, to your CAD standard and the governing code. Every drawing is checked against standards and structural analysis before it leaves our desk. We design distribution networks — we do not build them — so our whole practice is organised around one thing: accurate, documented, review-ready drawings.
