Building Measurement Survey

Is your building in scope? Now is the time to find out

New regulations under the Building Safety Act 2022 define “Higher-Risk Buildings” (HRBs) as those 18 metres or more in height or with 7 or more storeys. If you think you building in on the threshold Tetra Consulting can assist.
