All about Erasmian Engineering Projects to help your design office work like a dream.


About Erasmian: we offer freelance, contract and sub-contract services, offering more than 30 years of experience in various aspects of engineering, specifically in the design of piping and pumping systems, including mechanical and structural products.

Our journey started with the design of water pump stations and piped reticulation systems for irrigation systems and water supply to villages in various parts of Africa. With potable water becoming a precious resource, the treatment of water and later of effluent and sewage became a focus.

This then evolved into the design of process systems for various chemical process and later mining and mineral processing plants. The experience in the mining industry expanded to include design and 3D modelling of bulk materials handling systems, i.e., conveyor and chute systems and their supporting structures.

This varied experience enables Erasmian Engineering to offer a 3D modelling and 2D draughting service for most mechanical, piping structural and platework engineering designs, in Africa, Middle East and Europe.







Erasmian's Kobus Erasmus

Kobus Erasmus is the owner of Erasmian, offering exceptional experience in diverse engineering fields. Some of the roles he has fullfilled, in order of recency:

  • Freelancer: 3D Modelling and Design, BIM Enthusiast, Inventor & AutoCAD Expert. Working with mechanical, piping and structural disciplines for the bulk materials handling, minerals processing and wet minerals processing plant layout and design. Recent experience in heavy mechanical and structural 3D modelling and design was in the marine engineering industry, designing steelwork to be fabricated and fitted to a ship for use in the offshore construction industry.
  • Drawing Office Manager, for both Thyssenkrupp Industrial Solutions and Sandvik Mining Systems, including general & staff management, process and document control, project management, 3D modelling and draughting of mechanical and structural bulk materials handling equipment such as bins, hoppers, chutes, conveyors, etc., turn-key projects focused on materials handling, incorporating conveyors, crushing and screening plants, preparing tender budgets/proposals, mentoring, evaluating processes for continual improvement, global data conformity and quality management.
  • Senior Piping Design Draughtsman / Site Piping Supervisor / Project Section Leader at TWP Projects in Johannesburg doing office and site-based piping design/layout, 3D modelling using Inventor 2010 Professional, relining of drawing in case of changes, interpretation of specifications, etc. Projects included Burnstone Gold Mine, Balfour; Kumba Sishen Project Portfolio; Magareng Chrome Beneficiation. This included a multi-billion Rand portfolio of projects over a 5 year period. Work included a materials handling project, utilising ROM & crushed ore stockpiles, crushers, screening, DMS and spiral plants to separate product which is then stored in stockpiles.
  • Site Design Draughtsperson at Bateman Minerals, working on copper/cobalt process plant project in the southern Democratic Republic of the Congo. This being a brownfields project, it included a lot of site measurement and surveying, checking existing drawings against reality, updating P&ID's, establishing tie-in points, references, etc. Also worked on mechanical and structural layouts.
  • Draughtsman at High Tech Processing doing 3D modelling of brewery and soft drink process plants. Mainly piping design and plant layouts, PFD's and P&ID's, piping iso's, GA's and block layouts. Site surveying and measurement of existing plant to create as-built 3D models for brownfields projects.
  • Also worked as an Account Consultant, Sales Manager, Mechanical Fitter at Sasol, and Engineering Cadet with Safmarine.

Just some of the unique reasons to work with Erasmian:

  • We are able to assist in any phase throughout the project lifecycle, on any size project.
  • If we cannot assist, we can connect you with the right people from our considerable network of specialists. This includes highly qualified Mechanical, Structural and Civil engineers, whom we partner with to provide complete design packages to our clients.
  • Working with a single vendor means a simplified procurement of services and a single liability entity.
  • Our lean operation makes us responsive to client requirements. We can handle short notice requests – depending on location and scope.
  • We offer a combination of design skills for mechanical, piping, platework and structural in a single team. With decades’ experience on process plant layouts, pump & pipe system designs, we create efficient, maintenance-friendly systems, designed with human safety and ergonomics in mind.
  • We evaluate and compile the scope of work to ensure that the deliverables are equally understood by both parties, enabling time-line and costs to be controlled.
  • Our foundation is based on Ethics, Integrity, Confidentiality, Objectivity and Competence, to ensure our client benefits directly.
  • We comply with International Design & Quality Assurance Standards and Best Practices. Environmental, Health and Safety concerns guide our design work. We consider a list of requirements to ensure the model produced comply to the deliverables without sacrificing Accuracy, Quality and Relevance. An efficient 3D database is easily accessed by clients and drives methodology and structure.
  • Practical knowledge combined with advanced on-site assessment skills means the client receives a high-quality product.
  • Software we use: Autodesk CAD design software (AutoCAD, Inventor, Plant 3D, BIM360, Vault Professional, Navisworks Manage, Design Review, Recap).
  • We also use Sharepoint: every project has a Sharepoint portal with client access, acting as the primary document and drawing control hub.
  • Roles we have assisted: Process Plant Owners; Mechanical / Structural Engineering Design Consultants; Process Plant Design Consultants; Process Engineers; Buyers of Existing Plant; Engineering Consultants; End Clients; Structural, Mechanical & Piping Construction / Fabrication firms; maybe you?
  • Our quality work means that our clients want to work with us again on future projects.


From CADChain: "As part of the “5 Questions to an Expert” series, CADChain recently caught up with Kobus Erasmus, a 3D modeler for heavy steel fabrication, mechanical and structural disciplines, inventor, and AutoCAD expert. We spoke about Kobus’s vast experience in managing a drawing office, challenges he faced impacting the drawing and design offices, what precludes professionals from shifting from 2D to 3D modeling, and whether intellectual property protection is a pain point in the CAD field these days, among other things."
