Design 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 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:

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.

Crane Lifting Beam

The mother beam of the 40T ship loading crane at the Port of Townsville had been in service for over 30 years and was nearing the end of its service life. With regulatory compliance changes and much improved safety practices in the past 30 years, Xstrata Copper (now Glencore) engaged Orana Engineering to redesign the mother beam based on the existing beam and incorporating required changes to meet the current compliance requirements. This was also an opportunity to improve the current design by incorporating feedback from the crane operators and maintenance personnel.

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.

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.

MG07 Conveyor – Civil Design

Carborough Downs Coal Mine is an underground operation located in Central Queensland that utilises conveyors to transport mined coal to the surface for processing. As operations progress and new longwall headings are mined, new conveyor installations are also required. Designing a conveyor installation involves 3 major stages: the drive-head chamber design, the civil design, and the mechanical arrangement design.

Tank Static Line

All mine and industrial sites will list safety as their highest priority within their day to day operations. In line with this philosophy, management at Carpentaria Gold’s Ravenswood Operation enlisted the assistance of Orana Engineering to design a fall arrest system that could be easily removed and repositioned above the multiple leach tanks on site to allow for the safe removal and servicing of tank agitators.

Tank Farm Upgrade

Melbourne Bio Diesel’s (MBD) James Cook University (JCU) research facility required an elevated level area to allow the installation of a series of tanks for the purpose of storing fresh sea water. Orana Engineering was requested to provide a design solution that not only increased efficiency with the tank draining but to also improve safety around the new tanks.
