What this work involves
Establish existing service routes, levels, ground conditions and access before planning excavation.
- Excavation boundaries
- Removal and reuse of soil
- Levels and surrounding connections
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Coordinate opening changes with structural elements and visible proportions.
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.
Cost factors for this service
Costs depend on soil volume, access and disposal arrangements. Ask for the scope and selected specification to be described separately.
Bring this to the discussion
Photographs of the existing situation, available drawings and your requirements for groundworks & site preparation. Identify the elements that should remain.
Questions about the work
What should I discuss before arranging groundworks & site preparation?
Even a small extension may need groundworks. Foundation design, existing landscaping and service routes determine the extent.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
