In such cases, the owners misuse of the structure or systems may be the cause of any failure, and may bar recovery against either the contractor or designer. (Select the two alternatives that apply.) For example, an owner who provides project information represents (either explicitly in the construction contract or implicitly as imposed by law) that the information will be accurate. A QC checklist also typically includes other information like packaging requirements, on-site testing procedures and required inspection equipment. Minor defects are usually small, insignificant issues that dont affect the function or form of the item. is that after the project is delivered, the asset is put through it's paces, impacted by people and the environment, and often changes hands multiple times. If these defects can be traced back to an issue during the design or construction phase, and the contractor or another party was negligent, then you may be in a good position to claim damages or have the issue fixed. In other words, when taking ownership of a new home, building or asset, you should do a dilapidation report in order to capture latent defects.
