About

Scaff Inspector

Features
Read full description

The Scaff Inspector application has been developed to carry out scaffold inspections per UK government standards. The app helps users to add and inspect scaffolds even without the internet. While reviewing scaffolds, users can select scaffold faults from predefined fault lists, take photos and highlight photos, and draw signatures for authenticating inspection. Our standard inspection includes a thorough examination that ensures: - That the platforms comply with statutory regulations and the recommendations of TG20:21 - That both the access and egress are suitable and safe. - That the foundations are adequate, and are not likely to be disturbed or undermined. - That the lower portion of the scaffold is not liable to damage by interference, accident, traffic or any other extenuating issues. - That the scaffold is appropriately constructed to carry loads, following the guidance from the TG20:21 compliance sheet or design drawing. - That the scaffold is correctly tied, anchored and braced to maintain stability under load and environmental factors. - That the anchors have been installed and proof tested by a competent person. Once the inspector has received the anchor pull test they will save it on file. - That the scaffold complies with the requirements of the Local Authority, including lighting, hoarding and fenders, and in general is not constructed in a way that can cause damage or injury to persons due to protruding tubes, low headroom or other issues or hazards.
