Existing and proposed floor plans explain the alteration; sections and structural details explain the supports and load path. The required set depends on the building and the purpose of the documents.
Find the existing situation
Look for original building drawings and records of extensions or previous openings. A municipality or regional archive may hold documents. Use the address and known alterations to search, and remember that historic records must be checked against the present building.
Show the proposed change
Mark the wall, the opening position and the intended room layout. Distinguish approximate wishes from surveyed dimensions. A kitchen or furniture plan can support the brief, but cannot replace the structural assessment.
Add the structural information
The engineer determines which sections, elevations and connection details are needed. They can include the structure above, beam supports, columns and the supporting construction below. Coordinate the calculation report and drawing revisions so they describe one solution.
Keep a controlled document set
Agree who issues updates and who receives them. Do not let an older permit plan and a later site instruction circulate as competing versions. Retain the final assessed and as-built information with the handover records.
Frequently asked questions
Are sales drawings sufficient?
They help communicate the layout, but usually do not establish all structural details. The engineer will identify what additional records or investigation are needed.
What if no archive drawings exist?
State that clearly. The assessment must then establish which site inspection or investigation is required rather than assuming the hidden construction.
