What this work involves
The engineer needs reliable existing and proposed information. Coordinate calculations and drawings and identify what still needs checking on site.
- Existing structure and records
- Proposed change and loads
- Calculations and drawings
- Connections and bearings
- Design and permission coordination
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Base design and specialist assessment on measured facade details.
What the drawing needs to explain
Draw a scaled elevation showing existing and new windows together. Resolve the roof-edge, wall and window junction before deciding from an atmosphere image alone.
Decide this before construction
Photograph retained details before dismantling. Check the dimensions of new components against the actual facade before production begins.
Compare the complete intervention
Allow a separate item for making good around the junction. The new wall may be precisely priced while adjustments to existing pointing, mouldings and finishes remain missing.
Cost factors for this service
Complexity, missing information and scope determine the work. Design changes may require revisions.
Bring this to the discussion
Plans, photographs, existing calculations and the proposed alteration.
Questions about the work
Can calculations start before the design?
Early advice can help, but final calculations need sufficiently defined dimensions, loads and design choices.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
