Sub contractor performance review

“Having engaged G.A.Interiors on a varying level of sub contract packages over the past 6 years, I am very happy to endorse their services completely in all stages of the works from pre construction through to Pc and post completion. I have placed awards with them for dry lining packages in isolation but have also included SFS, Fire stopping and also joinery with equally impressive results. G.A.I have invested in their infrastructure enormously and are able to satisfy whatever requirements I have placed upon them in terms of ISO accreditation, construction line etc.”
