EV Charging Structural Engineering
EV charging infrastructure is usually installed on structures that were never designed for it. We assess what is there, design the canopies and foundations, and check whether a car park deck can carry what is being proposed.
What we cover.
Most charging installations land on an existing car park, forecourt or deck. The structural question is rarely about the charger itself and almost always about what it is being fixed to, and what the wider structure was originally designed to carry.
- Charging hub structural design
- Canopy and carport structural engineering
- Charger foundation and plinth design
- Car park deck load assessment for charging installations
- Solar canopy structural design
- Substation and transformer base design
- Cable route and trench structural detailing
- Structural assessment of existing forecourt structures
What ev charging structural engineering actually involves.
Canopies are wind-governed structures. They present a large surface with an open underside, which generates significant uplift, and they are frequently required to span without intermediate columns so that vehicle movements are not obstructed. That combination drives both the frame and the foundation design.
Multi-storey car park decks are the more common problem. Adding charging infrastructure means additional point loads, sometimes additional plant, and occasionally a change in how vehicles queue and stand. A deck designed decades ago to a superseded loading standard needs assessing against what is actually proposed rather than assumed to be adequate.
Where a canopy also carries solar, the two loading cases interact: permanent panel weight, wind uplift on a now-solid surface, and snow accumulation. Designing the canopy for the panels from the outset is considerably cheaper than strengthening it afterwards.
We design charging canopies for the wind case that actually governs them, assess existing car park decks against the added point loads and plant before anything is installed, and design for the solar case from the outset where a canopy will carry panels later.
Can an existing car park take EV charging infrastructure?
Often yes, but it needs assessing rather than assuming. Charging installations add point loads, sometimes plant, and occasionally change how vehicles stand and queue. A deck designed to a superseded loading standard may be adequate or may need localised strengthening, and the only way to know is to assess the existing structure against the proposed arrangement.

The codes behind ev charging structural engineering.
BS EN 1990 through BS EN 1999 govern the basis of design, actions, and the design of concrete, steel, timber, masonry and aluminium structures. Every calculation we issue references the relevant Eurocode part and its UK National Annex, and states which parts were applied.
Structural analysis and design in Tekla Tedds and Tekla Structural Designer, with Autodesk Robot, CSC Fastrak, CSC Portal Frame, MasterSeries and Hilti Profis used where a scheme suits them. Drawing production in AutoCAD, and modelling in Autodesk Revit where a project is delivered in BIM. Output is issued as readable calculations rather than raw software printouts, so a checker or a building control officer can follow the reasoning.
The Building Regulations requirement your local authority Building Control checks against. Our calculations and drawings are prepared to demonstrate compliance so your submission is accepted without back-and-forth.
Every report and calculation package is backed by professional indemnity cover, which is what lets a lender, Building Control or another engineer rely on it.

Common questions
Do you design solar canopies as well as plain shelters?
Yes, and it is worth designing for the panels from the start. Adding them to a canopy designed without them usually means strengthening.
Can you assess a multi-storey car park deck?
Yes. This is the commonest structural question on EV projects and it is frequently overlooked until late.
Do you work on forecourt and retail sites?
Yes, including canopies, charger foundations and the structural aspects of substation and transformer bases.
What information do you need?
The proposed charger layout and loadings, a site plan, and any existing structural drawings. Where drawings do not exist we survey what is there.
