Our Services

Today’s construction projects require a full range of consulting skills to satisfy not only the needs of economics and planning but also to harmonise the development within the environment and meet social needs. By recognising that every project is different and applying our commitment to engineering excellence, we provide practical, efficient and cost effective services to the construction industry. As environmental issues acquire an ever-higher public profile and legislative controls multiply, it becomes increasingly critical to enlist practical, experienced help in meeting environmental needs. Practical problem solving is at the core of our business and by deploying a wide range of skills, we provide innovative and sensitive solutions to environmental issues.

What People Say About Us

As a contractor that has to look at many drawings, you would be surprised at how great a difference two consultants could do the same work so differently with drawings.
If every client was shown a sample of the quality and style of drawing their consultant was going to produce for them at the beginning of the project, they would probably select someone like CJ Design.
Main reason being that if the client can clearly understand the drawing, then so will the contractor and the chances of getting a more accurate cost, will almost certainly prevail.
When a contractor is presented with poor information and potential risk of missing items, their price will have to compensate for this and the end client will always be picking this up.
If a client also has strict deadlines on tender returns, this is much more likely to happen when the drawings and equipment schedules are of the high standards produced by CJ Design are issued to contractors.

We have recently engaged CJ Design Partnership (CJ Design) to design the MEP engineering services for number of projects including a healthcare project at Medway Maritime Hospital. In 2020, we also completed a large commercial fit out project at Canary Wharf together. We have been exceedingly pleased with their performance and approach when delivering their services. Their professional team has consistently paid attention to detail and delivering on each project quickly, efficiently and within the code requirements. Additionally, the communication received from the team has always been timely, informative, and easily understood.
