Final settlement

For new installation projects, the design documents and the changes required are of primary importance. If something makes construction difficult during the process and changes are necessary, it is essential to communicate with the design institute; otherwise, it will be difficult to settle accounts later on. When I handle the settlements, I usually add a note stating that the on-site conditions should take precedence, and that the actual on-site drawings come from the design institute.

It depends on whether it’s civil engineering work or installation work; it seems from your question that you’re referring to installation. In our field, the installation process is based on the material lists provided by the designers. Once the cost estimators receive the drawings, their first task is to check whether there are any discrepancies between the quantities indicated in the drawings and those in the material lists. If any issues are found, they must contact the designers right away and raise these concerns during the drawing review process, with the findings being documented in the review records. If problems arise during construction as well, it’s necessary to contact the designers again, either to issue changes or to confirm things through project correspondence documents. At the time of settlement, taking all the above information into account, the quantities are included in the settlement.

Normally, the design drawings provided by the design institute are taken as the standard; there may be some discussions on site, and once signed by the designer, the supervisor, and the owner, they can also serve as a basis for settlement
