Design Drafting & EngineeringDesign Drafting

Design drafting is the process of graphically communicating the works that are to be performed for a project. When well executed, design drafting is cost effective and increases the likelihood of project solutions being delivered that are safe, easily maintainable, on schedule, on budget and consistently meet or exceed the original requirements. Design drafting provides an opportunity to visualise the proposed project outcome and ensures that all involved on a project are working towards common goals with sufficient detail.

Like all effective communications, accuracy, relevance and presentation are essential.  Design drafting must cater to the entire audience who will use and depend on the drawings, before, during and after the project.  Design drafted drawings are relied upon from the concept and construction stage of a project, right through to ongoing maintenance and operations requirements, and form the basis for future modifications and growth.  From well design drafted drawings, the ongoing process of drawing management and drawings revisions is greatly simplified.  For our clients this means the benefit of accessible, accurate and timely information on an ongoing basis......Read more | Show less

Orana Engineering’s unique and customised approach to design drafting strives to ensure that:

  • All aspects of a project’s implementation are fully considered to avoid unforeseen surprises;
  • Personnel of all engineering disciplines and professions involved in the project (client, project management, design, construction and maintenance) are fully informed and have given thorough consideration to the design and what is required of them to achieve it; and
  • Critical to brownfield operations, that there is no potential for drawings proposing a project’s scope to be confused with drawings of what is actually installed, avoiding an unsafe situation where site maintenance personnel could be working with an incorrect revision of a drawing.

Our projects are delivered to meet the HSEC, quality assurance, cost and schedule targets originally set.  Considering this, good design drafting does not necessarily reduce the cost of a project, rather it strives to increase cost efficiencies by preventing project cost and schedule blowouts, which can ultimately impact safety and quality.  What design drafting really targets is eliminating the negative impacts that insufficient or poor design drafting can have on the cost, quality and schedule of a project as well as the safety of those relying on the accuracy of these drawings.  Onsite design modifications during or after construction are far more costly and time consuming to resolve as opposed to modifications when they are identified offsite or before procurement of incorrect equipment.

The key to delivering high quality and valued design drafting services lies within our in-house resources, expertise and focus on quality.  Internal quality assurance systems at Orana Engineering are first rate and at the core of the design drafting we produce.  Our best practice approach means that our learnings are continuously incorporated into our work to benefit all clients.  We are experienced working with a wide range of tools for design drafting, such as AutoCAD, Inventor and other Autodesk products.

Our multi-discipline design drafting services include:

While design drafting can be offered as a stand-alone service which is inclusive of the necessary engineering certifications, our clients can benefit from Orana Engineering’s portfolio of other drafting related services such as drawing management and drawing revision while also taking advantage of other services provided by Orana Engineering including engineering services, project management and Client Engineer.

UG Conveyor Installations – MG32 Tripper Chamber

Maingate roadways mined to accommodate longwall conveyors at Glencore’s Oaky No. 1 underground coal mine can vary from a few hundred meters to over 4 kilometres in length. Transporting vast quantities of coal over long distances requires a significant amount of power. In some cases the drive-head power is insufficient or is constrained by the allowable belt tension and an additional drive/ power source is required to meet the required operating capacity. Commonly this additional power will come in the form of a driven conveyor tripper installed at a nominal point along the conveyor, which requires the appropriate excavation for the tripper installation inclusive of drives, tripper frame, braking and belt starter. more
