What this work involves
Define the purpose, size and position. Establish structural suitability and possible services before work. Water, dust and removal of cut sections belong in the preparation.
- Opening and material build-up
- Structural assessment where needed
- Service and reinforcement checks
- Access and protection
- Water, dust and waste handling
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Assess structural elements before finalising renovation phases.
What the drawing needs to explain
Create a phase drawing with three colours: repair now, improve later and investigate first. Mark where phases meet, such as roof edges, service routes and finished floors.
Decide this before construction
Address assessed causes of defects before new finishes conceal them. Plan comfort measures together with ventilation and necessary access to building services.
Cost factors for this service
Diameter, depth, material, reinforcement and access affect execution. Include protection and disposal.
Bring this to the discussion
Dimensioned drawing, position, photographs and structural information.
Questions about the work
Can an opening be made anywhere in a concrete floor?
No. The floor's function and the position of reinforcement and services need assessment. An engineer can advise on suitable alterations.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
