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.
Coordinate large facade openings with structure and the intended glazing divisions.
What the drawing needs to explain
Draw sightlines from two seats and show shading positions. Review the same layout in daylight and with interior lights on; privacy works differently in those situations.
Decide this before construction
Select window divisions, shading fixings and connection points in the same design round. Visible equipment then need not be fitted around completed finishes afterwards.
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.
