Safety, Quality & B.I.M.


Safe working has been a target at William Haley Engineering since its foundation. We have worked hard to develop a strong safety culture from erector to manager and director to welder.

Our occupational health and safety management system was certified to OHSAS 18001 standard in 2008 and has been continually reviewed and improved upon ever since.

This has enabled us to promote a safe and healthy working environment for all our staff by providing a framework that helps our organisation to identify and control health and safety risks, reduce the potential for accidents and improve overall health and safety performance.

CE Marking

William Haley Engineering products meet all the appropriate provisions of the relevant legislation implementing European Directives and this has been achieved by us to the highest possible level in attaining: CE BS EN 1090-1 FPC Execution Class 4 and CE BS EN 1090-2 WC Execution Class 4 enabling us to work critical sites such as Nuclear.


Continuous improvement and quality were placed at the heart of our business right from it’s foundation in 1986. In fact we were the first BCSA member to be registered to ISO 9001 in 1990 (then BS 5750). We inspect all steelwork 100% at our works before dispatch. We do the snagging at our works in our time and not in your time. Our welding procedures are Lloyd’s approved. We are a BCSA member and have achieved CE marking.

We express our culture in phrases such as:

“Right first time”

“Leave nothing to chance”

“Measure twice cut once”

“A place for everything and everything in its place”

“Measure to improve”

Building Information Modelling (BIM)

At William Haley Engineering we have been using our Tekla 3D modelling system as a Building Information Model since Tekla introduced the system

The future is BIM and we are working towards this. Whether it is producing cost estimates with Revit, planning erection sequences with Tekla 3D, engaging with the design team or discovering new efficiencies, BIM is an important part of our production and planning process.


2016 saw William Haley attain its EM BS EN ISO 14001 – Environmental Management Certification. This ensures that we adequately control environmental aspects, reduce the environmental impacts from our operations and ensure legal compliance.
