Quote: load-bearing wall opening
E.g.: passage created in a load-bearing wall between living room and kitchen
State the desired clear opening, location and use constraints. Design the solution for the actual building instead of selecting a beam from a catalogue. Feasibility, supports and site conditions need checking even for a small opening.
Assess the building first
AQC recommends checking structural condition and capacity for alterations. Have the specialist define investigations, calculations and assessment limits. Opening width alone cannot select a section or material.
Design the supports
Ask how loads will be carried and transferred, including affected lower levels. The quote must reflect designed beams, supports and possible strengthening. A standard steel beam or concrete for every large span is not automatic.
Assign temporary stability
Identify who designs, installs and checks temporary provisions. Request an approved sequence and conditions for removing supports. A generic cutting and installation order cannot replace the project method.
Confirm approvals
Luxembourg City lists structural alterations among work requiring permission. Confirm the application with the municipality responsible for your address. Examine private or co-ownership agreements separately.
Plan return to use
Define service identification and isolation, materials, access, dust and disposal. Request checks before enclosure and completion records. Confirm occupied areas for each stage.
Indicative prices in Luxembourg
On quotation
The price covers a structural alteration, not merely beam supply. Separate assessment, permanent work, temporary stability and making good. Tie the offer to the drawing revision and assumptions used.
Subsidies and grants
No grant is deducted from the budget shown here. If a quote mentions support, request the exact scheme and confirmation of your eligibility before including it in financing.
Frequently asked questions
Can every wall be opened?
Feasibility needs assessment; assuming more expensive strengthening cannot guarantee it.
Buy the beam before assessment?
Approve the solution and execution documents before ordering dimension-dependent components.
Is the property manager’s agreement enough?
Check required private decisions and municipal procedures separately.
Does assessment guarantee an unchanged budget?
No. Define assumptions, investigations and how discoveries will be handled.
