The construction industry boom in Sydney shows no sign of slowing down, and the city skyline is a forest of cranes that just keeps growing.

Infrastructure work is off the charts with the $20 billion Sydney Metro Project now in its second stage. Major commercial developments are under way in the CBD and the Australian Technology Park at Redfern, while Macquarie Park and Parramatta also have big projects under consideration. Retail and private housing, health and education sectors are also signing off on projects faster than you can say “tender”, while the re-zoning of previously industrial areas as residential and mixed use, not to mention new public housing around transport hubs, means tradies have never been more in demand.

If you’re busier than a one-legged man in an arse-kicking contest, the last thing you need to be stressing about is getting your trade drawings done for final payment. That’s where we come in. Drawable’s reputation for turning around top-notch as builts, as installed and electrical drawings is well deserved – we’ve been as this game for nearly 10 years, so we know what we’re doing. Need some Revit BIM, block plans, 3D models or evacuation plans? We do that too.

But do you know we also have the kit to do large-format printing and scanning? If your shop and construction drawings are a dog’s breakfast, give us a call and we’ll help you clean them up. There’s a beast of a machine in our Newtown office that prints out shiny new plans up to AO size.

You’re welcome.

Working With Companies Interstate

by Cam |July 19, 2017 |10 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 |8 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.

Types of trade drawings

by Dave |May 10, 2017 |4 Comments | Uncategorised | , ,

What are the different types of trade drawings completed throughout the stages of construction?

At Drawable we complete a number of different types of trade drawings depending on the stages of construction.

Trade drawings, sometimes referred to as technical drawings, are drawings or plans used by contractors, engineers and tradesmen that documents specific trade elements for construction. An example of a trade drawing is a drawing made for a plumber with unique symbols to show where all the water lines, sinks, faucets, tubs and toilets are to be located.

The type of trade drawing required depends on the stage of construction and the specific development requirements. Not all developments will require all types of trade drawings.

There are 5 main types of trade drawings completed by Drawable throughout the construction process:

  • Tender Drawings:

Tender Drawings are the first type of trade drawing completed during the construction process. They are the engineers vision for the project used for estimating/pricing the cost of the building to be.

These drawings convey a lot of information about the construction to enable the contractors who are quoting for the job to understand the project completely.

The detailed drawings include exact dimensions, specifications and positions of elements.

The contractors will use the Tender Drawings to create the Tender Package. A Tender Package normally consists of the detailed set of drawings as well as a specification document detailing materials, workmanship and required standards for the entire project.

  • For Approval Drawings:

After the tender stage the drawings become For Approval Drawings. The For Approval Drawings are checked by the client and any required amendments are completed.

These drawings are used to affirm that the contractor has correctly interpreted the overall requirements for the development.

The client will then approve and sign off on the drawings, preferably before the construction commences.

  • For Construction Drawings:

Once the For Approval Drawings are signed off they become the Construction Drawings. Construction Drawings are used by the contractors to complete the actual construction.

These drawings, just like the Tender Drawings, will still include all of the detailed and exact specifications which are required by the contractors to get the job done.

  • Revision Drawings:

During the construction process it may be necessary for changes to be completed on site. Revision drawings are completed to document the various changes completed throughout the construction.

A number of revisions may be required depending on how many changes are completed by the contractors.

If there are no changes during the construction process, Revision Drawings will not be required.

  • As Built Drawings:

As Built Drawings are the final set of trade drawing completed for the development project. These drawings are completed after the construction has been completed. They will document the final details of the construction including the exact dimensions, geometry and location of all elements of the work completed.

Depending on the project specifications set out during the tender process, As Built Drawings are not always required.

The As Built Drawings can be used as a record from which future changes and/or additions can be designed. They can also be used as a starting point for any future developments to the same building.
