HAVS monitoring software without the spreadsheets
HAVS monitoring means tracking each worker's daily exposure to hand-arm vibration from power tools so it stays within the HSE's action and limit values. Valegrid Flow calculates that exposure automatically from timesheets and recorded tool usage, producing HSE exposure points and A(8) values for every worker, tracked against the Exposure Action Value (100 points) and the Exposure Limit Value (400 points) — no spreadsheets.
Automatic HAVS exposure calculation from timesheets
Valegrid Flow works out each worker's hand-arm vibration exposure from their timesheets and recorded tool usage — no separate data entry. You get HSE exposure points and A(8) values for every worker without doing the sums yourself.
Vibration exposure tracked against HSE action and limit values
Exposure is tracked against the Exposure Action Value (100 points) and the Exposure Limit Value (400 points) — the two thresholds that matter under HSE guidance. Each worker's points sit against those values, so you can see where everyone stands without a month-end spreadsheet exercise.
HAVS assessments for subcontractor workers too
Manual HAVS assessments are supported, including for subcontractor workers synced from another company. Assessments are grouped by day and month, so reviewing a worker's exposure history is straightforward.
HAVS records ready for the health & safety file
Every calculation and assessment is kept as evidence for the health & safety file. If anyone asks how you monitor vibration exposure, the records are already there — nothing to dig out or reconcile.
How it works
- Step 1
Workers log time as normal
Timesheets and recorded tool usage feed the HAVS calculation automatically — no extra admin on site.
- Step 2
Valegrid Flow does the sums
Each worker's HSE exposure points and A(8) values are calculated and tracked against the Exposure Action Value (100 points) and the Exposure Limit Value (400 points).
- Step 3
Review and keep the records
Assessments are grouped by day and month for review, and records are kept as evidence for the health & safety file.
Frequently asked questions
- What is HAVS monitoring software?
- HAVS monitoring software tracks workers' daily exposure to hand-arm vibration from power tools so it stays within HSE limits. Valegrid Flow calculates exposure automatically from timesheets and recorded tool usage, producing HSE exposure points and A(8) values for each worker.
- What are the HSE exposure action and limit values for HAVS?
- The HSE sets an Exposure Action Value of 100 exposure points a day, above which employers must act to reduce vibration exposure, and an Exposure Limit Value of 400 points, which must not be exceeded. Valegrid Flow tracks every worker's calculated exposure against both values automatically.
- Can Valegrid Flow record HAVS assessments for subcontractors?
- Yes. Manual HAVS assessments are supported, including for subcontractor workers synced from another company. Assessments are grouped by day and month so exposure can be reviewed over time.
- Do I still need a spreadsheet for HAVS monitoring?
- No. Valegrid Flow calculates hand-arm vibration exposure automatically from timesheets and recorded tool usage, and keeps the records as evidence for the health & safety file. There are no spreadsheets to build or maintain.
Stop doing HAVS sums by hand
Valegrid Flow is UK construction management software built by a working subcontractor, with HAVS monitoring included — from £19 per active worker per month.
