Provide the opening design
Show the intended opening, the structure that remains and the drawing revisions relevant to the work. Include available structural information and identify who resolves design questions. Cutting method selection is part of scope review, not a substitute for the project’s engineering or authorisation process.
Explain access around the concrete section
Photographs and dimensions should show the cutting face, working space and access to the opposite side where relevant. Tell the office about floor levels, supporting arrangements and nearby services. These details help distinguish an accessible wall cut from a more constrained package.
Allocate support, lifting and removal
The cut layout and removal plan need to work together. State who is responsible for support, lifting, section handling and removal. Explain the proposed material route and whether follow-on reinstatement is required. Those responsibilities should be clear before the work is booked.
Your enquiry checklist
- Current drawings and required opening dimensions
- Information about the retained structure
- Access photographs and floor levels
- Support, lifting and section-removal responsibilities
