Trend since 2020.
Cumulative maximum envelope per year. Procurement activity varies with investment programme cycles (schools, roads, sports facilities).
Note : Note: a contract awarded in year N may consume its envelope spread across N+1, N+2, N+3. The annual curve therefore reflects procurement activity, not actual annual cash.
