Working With Companies Interstate

by Cam |July 19, 2017 |0 Comments | Blogs | , ,

Are you wondering if it’s possible for trade drawings to be completed interstate? 

At Drawable, we’ve completed many interstate drafting jobs for trade-based companies. The drafting process we’ve developed allows for trade drawings to be completed remotely without the need for face to face meetings with our clients. With today’s advancing technology the ability to work with interstate companies is greater than ever.

How do we do it?


  1. Experience & Knowledge: 

What separates Drawable from other trade drafting companies is our founder was a licensed electrician for many years. He understands what trade-based companies need in their drawings, to get each project over the line, and has ensured that this knowledge is passed onto all of Drawable’s drafters.

Drawable specialise in trade drafting and are therefore experts in the field. Having completed nearly 10,000 jobs in the past 10 years, we’ve done thousands of As Built drawings, Hydraulic Block Plans, Line Diagrams and Electrical Schematics, just to name a few.

This experience and industry knowledge provides Drawable with an extensive understanding of trade drafting. If you have a job for us, we’ve probably already completed many other similar jobs and therefore have a strong understanding of the requirements, regardless of the Australian state in which you reside.


  1. Process:

At Drawable we have developed a process that allows us to work remotely with our clients, without the need for us to be on site.

From our experience we have learned that the most efficient and cost effective process is for us to be provided with a rough sketch or drawing marked-up with any changes. This can be scanned and sent through to Drawable via email or Dropbox, along with any original Auto-Cad or Revit files. This process removes the need for Drawable to waste time on site, not only saving our clients money, but also allowing us to easily complete inter-state jobs.

At Drawable we receive all sorts of mark-ups or rough sketches which we then turn into detailed Auto-Cad or Revit files. We easily completed a set of lighting drawings for a Melbourne sports field where the contractor collected the raw data, marked it up and scanned it through to us. We didn’t need to attend the site nor meet the contractor in person in order to get the job done efficiently and effectively.

We have created a guide to ‘Marking Up a Drawing’  (here) to assist with ensuring a smooth and efficient process.


  1. Technology:

With today’s technology, Drawable are able to rely on communicating and sharing documentation via electronic means. We use cloud-based programs such as Dropbox to securely share documents including large Auto-Cad and Revit files.

Communication is available via email or phone and our drafters are readily available to answer any client questions. However we find that the need to communicate is minimal provided the mark-ups or rough drawings are clear and accurate.

We completed an interstate job for the Perth City Council fibre optic network. it was a breeze liaising with the contractor via phone and email and we easily developed a set of drawings detailing the underground fibre optic network cabling. We have also completed a lot of the park lighting drawings for a client in South Australia.

At the Sydney Drawable office we have an in-house large format printer and scanner that allows us to print and scan any plans from our end, removing the need for you to drop off or mail any drawings. You can simply share the drawings via email or Dropbox and we can take it from there!

Electrical Drawings

by Cam |July 2, 2017 |0 Comments | Blogs | , ,

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.

What is an as built drawing?

by Dave |May 23, 2017 |0 Comments | Blogs | , ,

As Built drawings document the completion of works and are an essential part of the contractor’s hand over manuals. As the need for documentation throughout the construction process increases so does the need for as built drawings and other drawings.

As Built drawings can also be called As Installed drawings, As Constructed drawings and As Executed drawings.

An As Built drawing documents the changes that have been made throughout the job and the changes that have been made since the last revision of drawings.

For example, in electrical drawings the design phase for a construction project the electrical circuits are named P1, P2 etc. (for power) and L1, L2 etc. (for lighting). On the as built drawings these circuit tags are changed to show the distribution board number and circuit breaker number that the lights (or power etc) are connected to.

For example: DB1 CB37

Another good example is that data outlets are numbered to the client’s requirements.

Sydney University uses a unique numbering system for the data network which shows the room that the cable is fed from, including rack number and port number of the patch panel. Then the room number that the outlet is located in and the number of the outlet in the room.

A typical data outlet tag in Sydney University looks like this. 524.

These can be quite challenging to add to an as built.

There are several stages that drawings take through a project, here’s a few examples.

A project will start with several stages of design drawings however the first set that a contractor will usual see for the For Tender drawings which are used for quoting.

Once the builder has been awarded the contract they take the role of Prime Contractor and pick electrical, mechanical, hydraulic, fire and security contractors to complete the project.

The next set of drawings are the For-Construction drawings where most the design changes have been made and these drawings allowing the contractor to start work.

The next set of trade drawings that aren’t normally required are Shop Drawings, these are required when a builder wants to see any potential changes the contractor can see before work starts.

Then we come to the Revision changes (usually shown as R1, R2 etc.) which document any changes the client has requested or any issues that have been resolved during the construction phase.

The next step towards As Built or As Constructed drawings is the most neglected, the contractor’s mark ups.

Pens, pencil, highlighters, chewing gums, blood, a bit of electrical tape and Bob’s your Uncle. A true mark up is not complete unless it’s been kicked around the work van for a few weeks, and has a generous splash of coffee and smudge of meat pie with sauce.


The last and probably most important stage is the As Built, As Executed, As Installed or As Constructed drawings, these critters help the contractor get paid!!

The As Built drawings are included in the hand over manual which also covers the products used during the jobs, their specification sheet and maintenance details.

As Built drawings can take anything from 5 minutes to hundreds of hours depending on the size of the project.

As the need for more details are required many Australian projects are now being completed using Revit models. Revit allows the engineers, contractors and clients to view every facet on the job in 3D. With addition of programs like Navisworks clash detections allows any potential issues to be resolved before construction begins.
