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.
Record seated sightlines rather than relying only on overview images.
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.
Compare the complete intervention
Include shading, controls and the finishes around glazing from the start. A proposal omitting them is difficult to compare with one that already addresses comfort fully.
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.
