Q013 (BB1M) Box Building (Modular)


Modular joint boxes feature under footways in various sizes and are constructed to specifications set out by Openreach for their underground networks. The process of modular box building includes digging and excavation, as well as core drilling, frame installations and more. As such, the skills and techniques required to ensure correct and safe work are many, so high-quality, specialist training is critical.

Operators working on the Openreach network must hold the relevant qualifications and certifications to do so in the UK. The Q Modules are a range of training courses approved by Openreach to ensure their workers operate to the correct standards and safety methods.  

Course Outline

Through a mix of practical and classroom-based exercises and tutorials, delegates will cover legislative and administrative knowledge and awareness while participating in practical tuition, focusing on modular box building on an underground telecoms network. 

The course reflects national standards and industry best practices and is fully accredited in line with regulations. In addition, choose to learn with Citrus, and delegates benefit from training in our custom-built training facilities and customer-first approach to how we do business.

Our occupationally and technically experienced trainers will coach delegates in this two or three-day course at a 1:4 delegate ratio, awarding successful delegates a Citrus Training and Openreach certificate following an end-point assessment (EPA).
