Inspecting and testing the build
The developer is required to ensure the below inspections and testing by an authorised representative of Lincolnshire County Council at the correct time in accordance with the Section 38 Agreement.
Responsibility for the works, and ensuring supervision and delivery in accordance with the specification and approved design lies with the developer.
The developer should provide a minimum of 5 working days’ notice to provide facility to carry out the inspections and tests detailed in each of the following key stages. Random additional bulk sample testing may also be carried out.
Should the developer fail to notify or allow facility for the key stage inspection, the retrospective testing details must be provided. In this instance only tests carried out by a UKAS accredited laboratory will be acceptable.
