Site Notes


CJS are a team of experienced design engineers, project leaders and draughtspersons with skills in all areas of engineering consultancy, conceptual design, layout & detail engineering.

CJS are able to provide a broad range of engineering design & drafting services, undertaking work at our fully-equipped office, or by supplying staff to work at your site under your own supervision.

We can act as an extension to your own drawing office, or undertake complete outsourced contracts. As we are a fully flexible team, the number of staff involved on your project can be adjusted as necessary to suit the programme. This ensures high levels of efficiency.

Previous projects have ranged from a simple task taking a few hours, through to a team of over 20 engineers working on a major design project for 2 years.

Established in 1988, we have a proven track record backed by customer testimonials and repeat business.

All in all, you'll have peace of mind that your work is being handled by skilled technical experts who are committed to exceeding your expectations.

  • You’ll appreciate talking to our agency division - we focus specifically in providing draughtspersons, designers and project engineers - the type of people we are.


  • CJS supplied 3 mechanical designers to work on site at a client in the nuclear industry. When there was a delay with the renewal of security clearance (outside of CJS control) for all contract staff working on the project, the CJS trio progressed the task at the CJS office for around 3 weeks until clearance was received, thus ensuring project deadlines were kept on track.
  • A CJS designer was working at a client's site on a project which was terminated at short notice. Typically the client would give 1 weeks notice to the agent. As our in-house office was very busy, CJS were able to bring the individual concerned immediately back in to the office, saving the client unnecessary cost.
  • CJS draftsmen working at a client sites have the ability to call upon the design staff back at the office for technical advice or information that may not be available on site, thus providing a comprehensive service that would not be available via a traditional agency.
  • Many clients appreciate our continuity of staff - the same individual can be allocated to your work over a period of time, reducing the learning curve with methods & standards, even if there are breaks in the work flow.
  • Clients benefit from our range of grades of staff within our in-house operations. Depending on your task, we select the relevant grade of engineer / designer / drafter which means clients only pay for the skill level required rather than a flat rate for all work.
