What this work involves
List equipment, lighting and controls per room. Coordinate routes with structure and finishes. Use professionals appropriate to the installation.
- Existing system survey
- Capacity and points
- Safe accessible routes
- Kitchen, bathroom and heating coordination
- Testing, records and explanation
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Make differences between existing and proposed situations explicit in drawings.
What the drawing needs to explain
Place existing and proposed elevations side by side and add a window-opening section. Mark visible changes and elements requiring adaptation inside.
Decide this before construction
Assess the existing detail before selecting products. Then coordinate insulation, ventilation and visible finishes so one improvement does not create an unexamined consequence elsewhere.
Compare the complete intervention
Include internal making good and possible sill adjustments with facade work. Compare options using the complete work package around the opening.
Cost factors for this service
Scope, access and replacement requirements determine the budget.
Bring this to the discussion
Plans showing equipment and points, with existing system information.
Questions about the work
When should connection points be final?
Preferably before walls and floors close. A room plan with furniture and equipment reduces later cutting and repair.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
