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 drawing revisions is greatly simplified. For our clients this means the benefit of accessible, accurate and timely information on an ongoing basis.
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 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:
- Mechanical and Pipework;
- Civil / Structural;
- Control Systems (P&ID’s); and
- Animations and walk-through.
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.

TK102 Bypass Piping
When tasked with a major repair to one of their leaching tanks, operations staff at Carpentaria Gold’s Ravenswood Operations enlisted the assistance of Orana Engineering to develop a solution that would allow for process operations to continue whilst leaching tank TK102 was out of service.Read more
UG Conveyor Installations - MG Chamber Design
Mining and transporting millions of tonnes of raw material every year requires significant infrastructure and planning for future works. The site engineers at Glencore’s Oaky No. 1 underground coal mine have engaged Orana Engineering on multiple occasions (MG33C and MG34) to design new conveyor drivehead excavations (chambers) to install conveyor drivehead equipment for development and longwall coal mining.Read more
UG Conveyor Installations - MG Civil Installation
The site engineers at Glencore’s Oaky No. 1 underground coal mine have requested the assistance of Orana Engineering to determine the extent of the civil work required to effectively utilise the drive-head equipment in newly mined chambers for conveyor installations for MG32, 33, 33C, 34, 35 and 36.Read more
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.Read more
UG Conveyor Installations – MG32 Tripper Civil Design
The site engineers at Glencore’s Oaky No. 1 underground coal mine have engaged Orana Engineering to determine the extent of the civil work required to install the maingate tripper equipment in MG32 longwall conveyor.Read more
UG Conveyor Installations – MG32 Tripper Mechanical Design
In high capacity longwall conveyor arrangements, the installation of a tripper will typical occur after the chamber has been fully developed. The installation designed by Orana Engineering for MG32 conveyor for Glencore’s Oaky No.1 underground coal mine detailed the arrangement of the tripper drives, brakes, pulley frame and load station.Read more
Underground Workshop Concept Design
Due to expanding operations, Glencore's Oaky North underground operations considered that there could be benefit to having an underground workshop including refuelling stations to reduce vehicle travel times and increase efficiencies of vehicle movements. Orana Engineering was engaged to provide concept design and estimating assistance for internal project approvals.Read more
Wall Kit Drafting
BHP Billiton Cannington Mine is a significant underground Silver and Lead mining operation located in Western Queensland. Following completion of the ore extraction from each stope, paste backfill is used to fill the open void, which stabilises the area and allows for mining of adjacent stopes. This is achieved by constructing a fill wall across roadways, which provides a stable wall for areas that are being back filled, eliminates intrusion from back filled areas, and allows the back filling to achieve a higher density.Read more
Water Polishing Plant Access Platform
The BHPB Cannington Port Storage Facility located at the Townsville Port operates a Water Polishing Plant for the treatment of site stored water. The Water Polishing Plant Filtration system requires regular maintenance in order to replace Filtration Rods. With the Filter Bank maintenance ports being at a level that cannot be accessed from ground level, it was necessary to arrange work platforms to perform this maintenance.Read more
Yokogawa DCS Upgrade
Since 2005 Orana Engineering has provided 24/7 support for Glencore's Oaky Creek Coal control systems. At the Coal Handling and Preparation Plant (CHPP) OCC uses a Yokogawa DCS as the primary control system, which was originally installed in 1998. The system is very robust and the hardware, software and its configuration has proven to be very reliable and highly cost effective.Read more
