1. Scope of Work
Termites considered the most dangerous household insects. They attack wooden doors, furniture and kitchen kits, destroying all household property, in fact any material containing Cellulose. This method statement explains how to treat and protect the building from termite attack. Anti-termite will be applied on Building substructure foundation side surfaces which directly in contact with soil.
The buildings to be treated from termite attack are; Sub Stations, Process Interface Buildings, AFD building. All the specifications written herein are based on the issued Building Construction Specifications, Saudi Aramco Engineering Standard and other related International Standard references applicable for this report to Saudi Aramco.
