Engineering Design

As a company that prides itself on its flexibility – a willingness to deliver the most effective engineering solution to any requirement – we place a great emphasis on our design skills.

From a single bespoke pressure vessel to a complex turn-key factory expansion, a detailed design is essential in ensuring a smooth project delivery, on time and within budget. Clients come to us for our ability to provide simple answers to difficult questions - incorporating complex process pipework into a confined limited space, detailing requirements of operating conditions and calculations of loads, it’s all in a day’s work for our engineering design team.

Whether a project involves structural steelwork or a complex chemical dosing system, we’re here to help and advise.

Design office capabilities

Our large team of designers and draughtsmen specialise in 2D and 3D modelling with the additional capacity to work with Building Information Modelling (BIM). We can develop and prepare drawings and models from specifications and outline plans, allowing clients to fully visualise the finished project. We have also established working relationships with selected consulting partners to commission services such as seismic and blast calculations.
