01
A clear condition statement
Are we in good shape, or are there material issues that need attention? RSA gives leadership a documented answer.
- Clear overall conclusion
- Reasons for any concerns
- Evidence behind the conclusion
Risk Surveillance Assurance
Make hidden facility risks decision-ready. From measured evidence to a defensible position on condition, remediation and capital.
Risk Surveillance Assurance (RSA) identifies and quantifies under-the-radar environmental and thermal risks across high-occupancy critical assets, then converts the findings into a formal opinion, prioritised remediation program and capital case leadership can act on.
IdentifySurface environmental biorisks that can remain under the radar in complex operating environments.
QuantifyTranslate measured evidence into a comparable view of asset condition and priority.
RemediateCarry findings into accountable actions and a capital model that supports funding decisions.
Why RSA exists
Inspection identifies observations. RSA turns them into a defensible position on risk, priority and action.
The challenge is rarely a lack of inspections. It is that material environmental and thermal risks can remain under the radar because findings stop short of a governing conclusion, a quantified view of condition or a funded remediation path.
01
From findings to a verdict
RSA moves beyond observations to a formal, attributable position on the condition of the asset.
02
From risk to a quantified condition
A proprietary composite determination gives leadership a consistent way to understand severity, compare assets and track change over time.
03
From recommendations to a capital decision
Material findings are carried into prioritised remediation and a financial model, giving management a clearer basis for deciding what to address and when.
What you get
Four connected outputs that move risk from evidence to action.
Each output is drawn from the same measured evidence, so the determination, remediation priorities and financial case remain aligned.
02
A comparable condition determination
A proprietary composite measure gives leadership a concise view of overall condition while preserving the underlying technical detail for specialist review.
- Comparable across assets
- Five underlying risk dimensions
- Clear tier and trend
03
A ranked action plan
Instead of leaving teams with a list of findings, RSA shows what should be addressed first, who should own it and what evidence is required to verify closure.
- Priorities in order
- Named owner
- Clear proof of completion
04
A financial case for action
RSA translates the remediation plan into investment terms so executives and finance teams can decide what deserves capital.
- Investment required
- NPV, IRR and payback
- Downside and sensitivity cases
The condition determination
0–100 composite
A proprietary composite measure gives leadership a concise, repeatable view of asset condition without reducing the underlying evidence to a single unexplained number.

What the determination considers
Five dimensions. One integrated view of condition.
RSA evaluates five distinct dimensions of environmental and operating risk through a proprietary scoring model. The method is applied consistently across examinations, while the detailed weighting architecture remains proprietary.
BIO
Biological exposure & contamination control
VNT
Ventilation & air handling performance
THR
Thermal survivability & mechanical integrity
RSP
Control, response & verification readiness
CNF
Standards & regulatory conformance

Designed to resist averaging-away risk. A significant weakness in one dimension can constrain the overall determination until the underlying condition is addressed.
How an engagement works
A disciplined assurance process built on a defined RSA model and criteria framework.
pūrtec first establishes the governing model for the asset, then gathers and challenges the evidence, issues the determination, translates findings into remediation and verifies closure.
01
Define the RSA model & criteria framework
pūrtec establishes the governing risk model, zone architecture, evidence requirements and applicable criteria before fieldwork begins.
02
Measure the environment
We collect the relevant facility, air, surface, ventilation and thermal evidence.
03
Analyze the evidence
Laboratory and technical findings are evaluated against the agreed criteria.
04
Challenge the analysis
Relevant specialists review the method and interpretation before a determination is issued.
05
Issue the assurance determination
We issue the formal opinion, condition determination, prioritised remediation register and financial case as one connected instrument.
06
Verify remediation & re-examine
Closure evidence is tested and the asset is re-examined so the determination reflects conditions after remediation.
Four audiences. Four decisions.
RSA is built to answer the question each reader actually cares about.
You should not have to become an environmental scientist to use the result. Each part of the engagement is designed around the decision a specific stakeholder needs to make.
01
Operations executives
“What do I need to know right now?”
See the problem areas, the priority actions, the responsible owner and whether closure is on track — without reading the technical annexes.
- Fast executive view
- Ranked priorities
- Clear accountability
02
EHS, health departments & CIHs
“What was measured, and where are we outside the line?”
Go directly to the methods, limits, measurements, exceedances and closure evidence needed for defensible environmental-health decisions.
- Methods + criteria
- Zone-level findings
- Verification evidence
03
CEMs, PEs & engineering
“Which systems are driving the risk?”
See the mechanical, ventilation and thermal conditions driving the determination, then translate them into defined remediation work packages.
- System-level diagnosis
- Technical work packages
- Measured re-verification
04
C-suite, CFOs, investors & boards
“What is the exposure, what will it cost, and is the investment justified?”
Receive a concise determination, the priority capital requirement and a financial model with return and downside cases.
- Condition + tier
- Capital requirement
- NPV, IRR + payback
For technical teams
Simple for leaders. Traceable for specialists.
The executive answer is concise, but the underlying evidence remains available for EHS, CIHs, engineers and other technical reviewers who need to test the basis.

Where RSA fits
For operating environments where a facility problem can quickly become a people, continuity or capital problem.
RSA is currently focused on three operating settings where leadership needs a faster, clearer view of environmental condition and remediation priorities.
Defence installations
Barracks, family housing and mission-support facilities where habitability and heat stress carry standing directives.
Cruise & marine passenger
Hotel and technical spaces aboard vessels where an environmental event can remove a revenue-earning asset from service.
Sports & large venues
Training, locker, hospitality and high-density environments with short turnaround windows and visible operational stakes.
pūrtec does not offer RSA to hospitals or healthcare providers. An RSA opinion is not a clinical instrument.
Next step
Give us the asset and the business concern. We will determine whether RSA fits.
A short scoping call is enough to understand the operating environment, the leadership questions that need answering and the practical shape of an engagement.
Request a scoping call →01 · Tell us the concernWhat is happening, which asset is involved and who needs the answer.
