Electrical Drawings

There are many types of electrical drawings that are used by a diverse range of technicians, electricians and engineers through the construction, engineering and maintenance sectors

Some of the electrical drawings we complete include schematics, line diagrams, lighting layouts, circuits diagrams, switchboard configurations, communications cabinets, control drawings, lighting and power layouts, As Builts and as installed, single line diagrams and many other types of drawings.

The Drawable team have completed 9,784 jobs over the last 10 years and we’ve pretty much seen in all, we have work for over 500 electrical contractors throughout Australia.

Here are some of the different types of electrical drawings we have completed.

  • Lighting and switching layout
  • Power and circuit drawings
  • Floorplans and furniture layout
  • Cable tray and conduit pathways
  • Electrical schematic drawings
  • Single line diagrams
  • Park and public lighting
  • Fibre optic pathways and core allocations
  • Switchboard layouts
  • Block plans
  • DALI lighting
  • Data outlet numbering and locations
  • Wiring looms for vehicles
  • Emergency and exit lighting
  • Control diagrams and circuitry

As the need for more complicated installations and wiring systems increases so does the need for documentation. Detailed electrical drawings and as built drawings allow the contractor, consultants and end user to manage their offices and warehouse with ease.

More than ever it’s before more important for the electrical contractors to capture and document relevant information through the construction phase to be added to the AutoCad drawings and Revit files to complete the As Built drawings, As Executed drawings or As Installed drawings.

For pretty much any project complete these days there are a set of drawings which evolve through the installation, they are as follows;

Tender drawings are completed by engineering or consultants allowing the electrical contractor to provide a quote and for the job “to be won”.

The next phase is to create the “For Construction” drawings which pretty show the changes that the client required for the installation to begin and provide a accurate starting point for the electrical contractor and electrical technicians.

Of course throughout the job there are changes and these are document as revisions, which allow the job to move forward and show all trades the relevant changes. In a lot of cases the revisions not only involve changes to the lighting, power and data drawings but also architectural changes which often affect the building process.

Around 10% of project in Australia are now being completing in Revit which allow everyone to look at the entire project in 3 dimensions which the objective being to resolve any potential conflicts with other trades and their equipment before the project begins.

In a Revit model we are able to see when and where an electrical cable tray will be in the way of a mechanical duct during the design phase, or when penetration for cables or plumber’s pipework will impact other services. Using a plugin programme called NavisWorks allows us to run clash detection reports showing every clash that will in one sweep.

Revit also allows the various trade to share the model, see the conflicts and resolve them with minimum fuss and well before the project starts.

To clarify a frequently asked question, work completed in AutoCad are 2 dimensional drawings or floorplans as they are otherwise known.

In Revit the workspace is called a model and both 3D images and 2 dimensional drawings can be printed from the program. From our experience electrical contractors get excited about seeing “3D”

In summary there are a wide range of drawings that are used throughout the electrical industry and all of them help tradesmen and technicians complete their work accurately and safely.

The Drawable team have pretty much worked on every type of electrical drawing and have developed a wide range of as built drawings to help our clients complete their handover manuals, meeting their contractual obligations to their clients and builders.
