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.
Gather orientation, glazed area and use information for technical assessment.
What the drawing needs to explain
Record window orientation, opening elements and existing shade. Add the main use periods so a specialist can assess the comfort question concretely.
Decide this before construction
Discuss glazing, shading and ventilation before finalising facade or roof openings. Coordinate required service routes before closing internal finishes.
Compare the complete intervention
Compare the complete comfort solution, including controls and maintenance. A lower glazing price says little if it creates a need for other measures or adaptations.
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.
