What protection is installed and what condition is it in?

System upgrades & retrofits
Improve existing protection with a practical, evidence-led plan.

MERCURY FIRE PROTECTION SYSTEMSIllustrative project scene
WHEN THIS IS THE RIGHT FIT
A clear route for the work in front of you.
Existing buildings may change occupancy, layout, process or risk while their fire systems remain unchanged. Mercury studies current conditions, identifies priority gaps and develops a phased upgrade route that considers what can be retained, what must change and how work can be carried out around an operating property.
Choose this route for ageing systems, altered buildings, recurring defects, capacity concerns or a planned modernisation.PROJECT QUESTIONS
Decisions the work
must resolve.
Good project delivery turns uncertainty into agreed actions, responsibilities and evidence.
Which gaps create the greatest operational or safety concern?
What can be retained, repaired, extended or replaced?
How can the work be phased around building operations?
MERCURY SCOPE
Work organised around a usable outcome.
The exact scope is confirmed after reviewing the site, available information and project requirements.
- 01Existing-system condition survey
- 02Gap and priority register
- 03Capacity and interface review
- 04Repair, replacement and extension planning
- 05Phased installation and change control
- 06Retesting and updated system records
WHAT THE CUSTOMER RECEIVES
Useful deliverables.
Visible progress.
Each stage should leave the customer with clearer information, verified work or an agreed next action.
A visible condition baseline
Existing assets, limitations and priority concerns are organised into a usable starting point.
A proportionate upgrade plan
Recommended actions distinguish immediate priorities from planned improvements and avoid unnecessary replacement.
Updated, retested protection
Modified systems are checked after the work and the relevant records are brought up to date.
EVIDENCE BEFORE CLOSE-OUT
Completion should be understandable.
- Condition findings and agreed priority list
- Records of completed modifications and replaced assets
- Functional retest results and updated documentation
A clearer, safer and more maintainable existing system improved around the building’s real condition and operational limits.
