SILENCE HILLS INVESTMENTS

Award notices print a supplier’s name however the buyer typed it. GIST folds the spellings it can recognise onto one profile, so this is what has been published under this name — not necessarily everything this firm has won.

Compiled from published award notices and linked to the notice each figure was read from. GIST reports what was published and does not verify, rank, or interpret it. Confirm any figure against the notice before relying on it.
