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.
Create an element register with dimensions, condition and intended treatment.
What the drawing needs to explain
Prepare a detail sheet for the door, frame, skirting and wall together. Identify retained elements, refinished surfaces and locations requiring bespoke work.
Decide this before construction
Dismantle retained elements only with an agreed recording and storage plan. Take final bespoke measurements after assessing the adjoining substrate.
Compare the complete intervention
Separate retention, repair and new bespoke work in the quotation. This shows the preparation and protection effort alongside the visible end result.
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.
