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.
Use survey photographs and sample areas as recorded design references.
What the drawing needs to explain
Mark intact, damaged and unassessed areas on photographs. Add the old-to-new junction detail with proposed materials and treatment.
Decide this before construction
Start with a survey and trial repair, reviewing the result before treating the whole surface. Protect retained elements while removing adjoining material.
Compare the complete intervention
Price investigation, sample work and repair extent separately. Agree how findings after exposing the substrate are recorded before expanding the repair area.
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.
