Quality assurance: how the work is checked
Your calculations have to satisfy building control, and whoever builds from them has to be able to use them. This page sets out how the work is checked on the way there, and what happens if something still needs to change.
How the work is checked
Instant quotes
Instant quotes are scope reviewed by an engineer. Want an engineer to look first? Get in touch.
A manual quote is prepared by an engineer from your drawings in the first place.
Before the calculations: a call to go through the design
Once you order, your engineer introduces themselves and books a short video call with you. You go through the design together before anything is calculated, so the first draft starts from the right information.
Before delivery: the calculations are reviewed
Your calculations are reviewed before they are issued to you.
Throughout: a certified quality system
Our quality system is certified to ISO 9001. That means it is written down and audited against an independent international standard.
After delivery: building control
Building control is the independent check on the calculations. Our calculations are 100% approved by building control. If yours are not approved, you get a refund, as set out in our terms and conditions.
If building control has a question about the structure, it comes to us, not to you, and answering it costs nothing extra.
Building control may ask for a structural element we could reasonably have foreseen but did not quote for. If so, we provide it at no extra charge.
On site: a free change request
One change request is free on every job. Use it if building control asks for a change, or if what is found on site is not what was drawn.
Changes after that are priced before anyone commits to them, and always cost less than a new quote.
What it costs
The checks on this page are part of the price you are quoted. None of them is an extra.
The price itself is set by the structural work in your project and the delivery date you choose. There is no hourly rate. The few things that can change the price are set out on how the process works.
When you get it
You choose the date. There is no standard turnaround: when you order, you pick the delivery date that suits your project, and the price follows the date.
What you receive
- Structural calculations for building control: the full calculation document they ask for.
- A contractor pack for whoever builds it: a structural layout showing what goes where and what size, with diagrams they can work from on site.
- A ground conditions check for your site, built into the foundation design.
- Your project hub, showing what is happening now, what is next and anything we need from you, with your documents and invoice alongside.
What happens next
- Tell us about the project, and your quote is emailed to you.
- Choose your delivery date and order.
- Your engineer goes through the design with you on a video call.
- Your calculations and contractor pack are emailed to you and kept in your project hub.
- You submit to building control. Any structural questions come to us.
Each step is set out in full on how the process works.
Credentials
- £500,000 professional indemnity insurance. The cover needed is not set by the value of the whole build: a claim over a beam we designed would relate to the consequences of that issue, not to rebuilding the house.
- Chris Porthouse, one of our directors, is a chartered structural engineer (MEng CEng MIStructE).
