Structural Engineering & Steelwork Design
PD Engineering Consultancy Ltd, based in Kensworth near Luton, provides structural engineering for residential and commercial developments — from concept through to construction. We design and analyse structures in steel, reinforced concrete, masonry and bespoke fabricated elements, for both new build and refurbishment.
The service is built for main contractors, steel fabricators, developers and architects who need drawings and calculations that work on site, not just on paper. Every design is developed in line with current building regulations, relevant design standards and your project-specific requirements.
What's included
We cover the structural scope from first sketch to the last site query:
- Frame analysis — frame and finite element analysis for new build and refurbishment structures
- Structural steelwork design — primary steel frames designed for safety, efficiency and buildability
- Connection design — detailed design and detailing to support fabrication and installation
- Secondary steelwork — extensive experience in secondary steel and architectural metalwork
- Load calculations and structural assessments — including assessment of existing structures
- Calculation packages — clear, checked calculations to support your submissions and approvals
- Fabrication and installation drawings — documentation developed to work in the workshop and on site
We also carry out lifting studies and thermal modelling where a project needs them, and we can pick up temporary works or specialist analysis on request — just ask when you call.
Standards and codes
All designs are developed in accordance with current building regulations, the relevant design standards for the materials involved, and any project-specific requirements or client standards you work to.
If your PQQ or design brief calls out particular codes, professional memberships or insurance levels, tell us at enquiry stage and we will confirm in writing exactly what we hold and work to before you commit.
Our work
Project example: Kier, Watford Riverwell balconies
The challenge. Complex balcony steelwork that needed careful coordination across several disciplines, on a live contractor programme.
What we did. We provided the structural steel design, the detailing, and integration support with the wider project team.
The outcome. Fully compliant, buildable solutions that made fabrication and installation straightforward, and the package was delivered on programme.
As a project manager for a Tier 1 contractor put it: “PD Engineering provided clear, buildable engineering solutions that integrated seamlessly with our wider project team. Their technical knowledge and practical approach helped reduce risk and keep the programme moving.”

Frequently asked questions
Can you provide calculations for a building control submission?
We produce structural calculation packages and detailed design developed in accordance with current building regulations and relevant design standards, which are used to support project approvals. Tell us who you are submitting to and what format they want, and we will match it.
How quickly can you turn a package around?
It depends on the size of the frame and how much information is already available. Give us your programme dates when you call and we will tell you honestly whether we can hit them before you commit.
Do you visit site?
Yes. We support projects through fabrication, installation and handover, and we carry out structural assessments of existing structures for refurbishment work. Site attendance is agreed as part of the scope.
Do you work directly with steel fabricators?
Yes. We produce detailed structural detailing to support fabrication and installation, including connection design and secondary steelwork, and we stay available to answer workshop and site queries.
Can you handle the mechanical and architectural metalwork side too?
We do. We specialise in integrating complex structural systems with architectural and mechanical designs, and we have extensive experience in architectural metalwork and secondary steel, so one team can coordinate the lot.
How it works
- Enquiry and information. You tell us the structure, the programme and what already exists — architect's drawings, survey information, loadings or a fabricator's model.
- Analysis. We build the frame or finite element model and test it against the loads and conditions your project faces.
- Calculations and drawings. We produce the calculation package and the structural details, including connections and secondary steel.
- Checking. Designs are reviewed and coordinated with the architectural and mechanical work so clashes and construction risk are picked up before issue, not after.
- Fabrication and site support. We stay available through fabrication, installation and handover to answer queries and keep the programme moving.
Why choose us
Buildable details. Buildability, safety and efficiency drive every decision. Drawings and documentation are developed to work in fabrication, installation and handover — not to be redrawn on site.
Multi-discipline coordination. Because we also deliver mechanical, electrical and controls design, we can integrate complex structural systems with architectural and mechanical work in one place, which cuts the risk of clashes between packages.
Proven delivery. We have supported Tier 1 contractors and technically complex construction projects, including specialist balcony steelwork and bespoke architectural metalwork.
Strong analysis. Finite element analysis, frame analysis, lifting studies and thermal modelling in house.
How our fees work
Every structure is different, so we price against your actual scope: the size and complexity of the frame, how much connection design and detailing is needed, the level of site support you want, and the programme dates you have to hit.
Tell us what you have — even if it is only outline architectural drawings — and we will set out clearly what is included before any work starts, so there are no surprises on the invoice. Please confirm the fee basis with us directly, as it varies by project.
