Clarify the scope of the stage
Compare the contract, cost estimate, design changes and the works listed in the certificate. The heading 'base preparation' may cover different operations. It is helpful to mark which areas have been presented, which are not yet ready and which actual quantities need checking before construction continues.
Collect documents before structures are covered
Request available as-built drawings, concealed works records, information about materials used and the results of checks carried out. Photographs are useful when clearly linked to a location and date. An image of an isolated detail without an overall view does not always show which part of the house it belongs to.
Distinguish comments by how they can be verified
Some signs are directly visible; others require measurements, access to documentation or a specialist in the relevant field. An unconfirmed assumption should not be recorded as an established defect. If an important area is inaccessible, this is recorded separately when defining the inspection scope.
What to prepare
- The scope of the stage under the contract, cost estimate and latest changes.
- A house plan marking the areas to be checked.
- Documents on materials and completed concealed works.
- Photographs taken before structures were covered, linked to their locations.
- A list of comments and questions for the technical specialist.
What to bear in mind
A visual inspection does not automatically confirm every concealed parameter. The need for opening up and instrument-based checks is determined for the specific task and agreed in advance.
Outcome of preliminary preparation
Preparation results in a targeted list of checks and comments that makes it possible to discuss the actual condition of the stage, rather than just an overall impression of the construction work.
