2D & 3D Engineering Design & Modelling

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

From a single bespoke pressure vessel to a complex turn-key factory expansion, a detailed design is essential to ensure a smooth project delivery, on time and within budget. Clients come to Richard Alan for its 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 its engineering design team.

Whether a project involves structural steelwork or a complex chemical dosing system, help and advice is always available.

Design Office Capabilities

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