Our Quality Control procedure

To support our professional approach, we adopt a comprehensive internal quality control procedure to ensure all designs are prepared, presented and checked by a Senior Engineer or Director before being distributed in accordance with industry standards. Typically, we issue all design initially in ‘Draft’ format which is intended to prompt discussion and allow street licence or party wall applications to proceed. On receipt of comments, designs can be issued `For Approval’ or `For Construction’. When designs are subject to internal customer or third-party checking, we can provide full formal calculations to demonstrate suitability of the structure.  

All design drawings are done manually and are not generic software generated. We operate with the latest drafting software and utilise several bespoke and industry design analysis packages. In addition to this, we embrace CDM and H&S design regulations and have a zero-tolerance approach to non-compliancy, poor workmanship and dangerous site installations.  

We have a zero-tolerance policy towards non-compliancy and unsafe working methods and embrace our responsibilities under the CDM Regulations 2015.  All our engineers are required to complete external CDM training, as well as follow our in-house ISO 9001:2015 accredited QA procedures. 

Working to British Standards, Eurocodes and others

We work to the latest codes of practice including British Standards and Eurocodes, as well as industry guidance, and are committed to designing out risk wherever possible.   

We also use the latest software to undertake our analysis and design, producing innovative designs which are uncluttered and clear to follow. 
We offer guaranteed turnaround times with accelerated options available.  Project costs can be agreed on either a total payment, or hourly rate basis.  Please get in touch for more information.
