SPS Technology proudly announces our strategic partnership with structural and civil engineers, Design4Structures (D4S).
Founded in 1992 as a specialist steelwork detailing firm, D4S has evolved into a multidisciplinary engineering consultancy integrating structural, infrastructure and construction expertise. The D4S team supports contractors, developers and architects by streamlining construction with improved technical detailing.
To introduce our new partners, we sat down with D4S’s Simon Chatwin (Director of Construction Modelling), Adam Harkin (Head of Offsite Engineering) and Matthew Baker (Senior Structural Technician) to discuss their thoughts on the partnership.

Early Stage Coordination to Reduce Costs & Delays
By working with D4S, we ensure our stadium and special applications projects benefit from early coordination, reducing the risk of delays and unexpected costs.
What value does fully coordinating the design to a manufacturing level of detail early on in the process bring to the client?
Matt Baker (MB):
“Coordinating early on really helps identify any clashes or design issues before things get too far along in the construction programme. It’s all about catching issues as soon as we can to prevent delays and frustrations further down the line – we can ensure programme schedules are met and construction packages are issued on time.”
Adam Harkin (AH):
“For me, the biggest benefit here is cost certainty. When you get everything lined up upfront, you don’t have to worry about something unexpected throwing off the entire budget later down the line. With full fabrication details in place, anyone quoting knows exactly what they’re working with—no surprises, no caveats. It lets you draw a clear line in the sand. And if anything does change after that, you can go back and investigate why, knowing everyone was on the same page to start with. It just gives everyone in the supply chain, whether at the top or the bottom, confidence in what they’ve quoted and reassurance that the costs are solid.”
Simon Chatwin (SC):
“To summarise what Matt and Adam have said, it all comes down to cost and time savings. We’ve demonstrated this by adhering to these principles and successfully delivering client projects. In turn, we can continuously upskill our own employees and refine the process through the variety of contractors, developers or clients we work with. We gain valuable experience to leverage in future contracts – it’s a win-win situation for everyone involved.”
Setting New Standards in Precision
Ensuring SPS panels are correctly detailed from the outset optimises structural integrity, enhances efficiency and eliminates costly errors. This means faster, more reliable project execution. With D4S, we’re setting new standards in precision.
What’s different about detailing SPS versus standard detailing of other materials?
Matt Baker (MB):
“Detailing SPS (Sandwich Plate System) materials involves unique considerations compared to traditional materials. For example, SPS panels require specialised attention to ensure proper sealing of the core material. Unlike standard materials, which may need a straightforward bolt hole, SPS panels often need oversized bolt holes for full welding around the hole. This creates a secure seal critical to the panel’s performance.
Utilising Tekla, however, ensures we can adapt quite easily to the system, presenting us with a robust collection of components that streamline much of the work. Many tasks are often handled automatically, which saves us time and effort. Of course, we also have our in-house software development team, who play a role in developing custom components and macros where required.
The most crucial element, however, is to maintain a solid understanding of the unique details involved. While our components excel at managing standard specifications, when we step outside of those norms, that foundational knowledge of how things are constructed and the fabrication process becomes vital.
By developing these tools in collaboration with SPST, we’re producing high-quality work and evolving our capabilities to work as efficiently as possible alongside them.”
Collaboration That Drives Superior Outcomes
The SPS Technology and D4S collaboration eliminates bottlenecks, enhances problem-solving and promises superior outcomes for every project.
Has it been a more efficient process working with SPS Technology than some of the other projects you’ve been involved with?
Matt Baker (MB):
“Absolutely, I’d say the collaboration aspect is really strong here. It doesn’t feel like we’re just following orders in the design process; instead, [SPST] genuinely value our input and proposals. We feel like we are a part of each other’s team.
They’re receptive to our insights and expertise, which fosters a great working relationship.”
Simon Chatwin (SC):
“SPS Technology is a perfect example of a forward-thinking company. They’re clearly committed to being the best in their market and want to be recognised for it. However, they understand that achieving this goal requires partnering with like-minded organisations. These partnerships not only fill in the gaps in their knowledge and expertise but also help propel them forward on their journey—just like we need.”
Adam Harkin (AH):
“Feeling part of the SPST design team aligns perfectly with what we’re striving for as a business. We’re aiming for a unified collaboration internally, and if we can extend that to our external partners, it enhances the whole process. It’s like we become an extension of each other’s teams, which is fantastic!
More companies need to grasp this concept. In the construction industry, if you don’t come together and cooperate, you risk being left behind. That’s what makes SPST so refreshing; they truly get it.”
Building The Future Together
Sandwich Plate System is a revolutionary material with properties unlike any other. For civil engineering projects, SPS is a finished product ready to install immediately. It requires the use of common details while simultaneously demanding the thoughtful application of engineering in other details. It is this lateral thinking that keeps us at the forefront of offsite manufacturing – and now we’re backed by D4S’ understanding of engineering, construction modelling and detailing.
We can’t wait to show you what we’ve been achieving together, and we hope you’ll help us welcome D4S to our network of partners!
