Mechanical Design

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 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.

BIM, 2D and 3D modelling

Our 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.

Our range of design tools include:

STAAD Pro V8i:

  • Calculation tool for structural analysis and design
  • Generates loads as per specific building codes


  • 3D structural modelling and drawing
  • Rapid implementation of design changes
  • Automatic component detailing, parts lists, design data output
  • Assembly drawings and build sequences


  • Pressure vessel and heat exchanger design, analysis and evaluation

Autodesk Inventor Professional :

  • 3D mechanical design, documentation and product simulation
  • Integrates 2D and 3D data into a single design environment
  • Ideal for the design of complex pressure vessels and rotating mechanical equipment


  • Used for the generation of General Arrangement and detailed fabrication drawings
  • Integration of output from Tekla and Inventor into project models and overall layouts.

Intergraph CADWorx:

  • Pipework modelling and the production of isometric fabrication drawings
  • AutoCAD-based, fully intelligent 3D plant models with piping, cable tray and HVAC ducting Includes hundreds of metric and imperial pipe specifications. Library of over 60,000 components
  • Automatic isometric generation with parts lists
  • Collision detection, enabling complex pipe-routing designs

DFMA (Design for Manufacture & Assembly) and off-site build

Utilising BIM in our range of standard products enables us to collaborate in complex supply chains. By using CAD software, cloud-based asset management and modern manufacturing technologies, we can provide a Totex approach to asset investment in all our DfMA and off-site modular build projects. Design, manufacturing, assembly and testing of a total project, supplied or delivered in-house, ensures non-reliance on third party sub-contractor and allows for complete control over project delivery, resulting in:

  • Site installation time being significantly reduced
  • A reduction in site safety risks
  • Reduced multi contractor interfaces on-site
  • Testing and commissioning completed prior to delivery giving the client early confidence of project success


We can provide a 3D point cloud scanning service

  • Accurate to within a few millimeters it provides accurate and detailed information of the site
  • Reduced site visits required as it lessens the need to get into difficult or dangerous areas and therefore improves safety
  • Can be used for taking measurements, overlaying new structures or equipment in Autocad or Tekla

Example of a 3D scan is shown below.



With a production facility of 60,000 sq.ft combined with an expanding team of experienced chartered engineers, fabricators and coded welders, we can deliver all aspects of fabrication for any commercial project – large or small.

With expertise ranging from bespoke storage tanks to major fabrication projects encompassing the highly skilled manufacture of pressure vessels and reactors, structural steelwork, sheet metalwork, pipework systems and complex speciality process equipment, we have served multiple end user clients in the chemical, pharmaceutical, beverage and water treatment industries.

Projects can be stand-alone, delivered directly to the client for their own end use or as part of a turn-key in-house installation. With vast experience of working with stainless steel, carbon steel and exotic metals, we are accomplished in highly skilled manufacture across a multitude of capabilities.

With all fabrication work carried out on site, and to the highest standards, Richard Alan have gained an outstanding reputation for world class engineering.


Our dedicated team of NEBOSH qualified project managers and engineers can oversee full installations, with project capabilities including:

  • Vessels and pipework, including on-site fabrication
  • Structural steelwork
  • Specialist equipment
  • Thermal and acoustic insulation

Adding value to our service is our experience as site principles for Health and Safety, CDM and supervision of sub-contractors, especially on COMAH top tier sites. We are familiar with site safety systems such as induction procedures, method statements, risk assessments and permits to work. In addition, our teams of site operatives hold a spectrum of competency cards ensuring we are capable of handling anything from small, local installations and plant upgrades to multi-million-pound contracts for global corporations.
