Corbelstone Builders Quarterly Risk Review, Q3 FY27

Risk review presentation: heat map and top ten

A risk review presentation has to show an audit and risk committee which risks moved, whether the controls are actually working, and what it is being asked to escalate. Corbelstone Builders, an invented Australian commercial builder, places its top ten risks on a three by three heat map, reports eight of ten key controls effective, and brings two escalations for the board.

CORBELSTONE

Audit and Risk Committee · Q3 FY27

Quarterly risk review, January to March 2027

Ten top risks, three rated higher than last quarter, two escalations for the board.

Naomi Wiremu, Head of Risk

Paper for the committee meeting on 22 April 2027

Committee paper 4.1

Slide 1 · cover · Names the committee, the quarter and the headline movement before any detail.

The quarter

Corbelstone delivered 14 projects across Queensland and New South Wales this quarter. Subcontractor failures across the industry pushed our top risk higher, and two fixed price contracts are tracking over budget. Safety controls held.

FOUR THINGS TO KNOW

Three risks up

Subcontractor insolvency, fixed price overrun and cyber attack are all rated higher than in Q2.

Two risks down

Labour shortage and silica exposure fell after new controls took effect.

8 of 10 controls work

Ten key controls were tested this quarter. Two were only partly effective.

Two escalations

Both go to the board in May, with a recommendation for each.

Slide 4 · metrics · The top ten risks with owner, rating and trend, the register the committee actually signs off.

Incidents this quarter

All sites, employees and subcontractors, 488,000 hours worked from January to March.

2

Lost time injuries

A frequency rate of 4.1 per million hours, down from 6.0 in Q2. Both were hand injuries during formwork.

1

Notifiable incident

A scaffold collapse with no injury, reported to the regulator the same day and closed in March.

46

Near misses reported

Up from 31. Read as a reporting gain after toolbox talks, not a rise in danger.

05

Slide 5 · metrics · Safety incident numbers for the quarter, because in construction the people risks come first.

Controls tested

Ten key controls tested between January and March. Eight effective, two partly effective.

Height safety permits

Effective. 60 permits sampled, all complete.

Silica dust monitoring

Effective. All readings below the exposure standard.

Subcontractor financial checks

Partly. Three trades not rechecked in 12 months.

Variation approvals

Effective. No unapproved variations found.

Cost to complete forecasts

Partly. Two projects forecast late in the month.

Licence register

Effective. Every licence current on 31 March.

Backup restore test

Effective. Project files restored in 3 hours.

Defect close out

Effective. 94% of defects closed within 30 days.

Wet weather allowances

Effective. Included in all five new tenders.

Inductions before site entry

Effective. 120 workers sampled, none missed.

Slide 6 · checklist · The ten key controls tested this quarter and how each performed.

How a risk is escalated

Each step has a time limit. A risk rated high on both axes skips straight to step three.

1

Site

Project manager logs the risk in the register within 48 hours and proposes a treatment.

2

Risk owner

The executive owner rates it and agrees the treatment within a week.

3

Executive team

Reviews every risk rated high on likelihood or impact at its fortnightly meeting.

4

Committee and board

Any risk rated high on both, or rising two quarters running, comes to this committee.

Slide 7 · process · How a risk moves from a site to the board, so the committee can see where escalations come from.

THIS QUARTER

Safety controls are working. The risks that grew are commercial: who we subcontract to and what we sign at a fixed price.

Slide 8 · takeaway · The single message for the committee this quarter.

TWO ESCALATIONS FOR THE BOARD

Board meeting, 13 May

Endorse both

R1: recheck all 38 key trades quarterly, not yearly. R3: no fixed price contract above $15M without board sign off.

Slide by slide

Slide one names the committee, the quarter and the headline. Slide two gives four things to know: three risks up, two down, eight of ten controls working and two escalations. Slide three is the heat map. Slide four is the top ten table. Slide five reports incidents. Slide six lists the ten controls tested. Slide seven explains how a risk moves from a site to the board in four steps with time limits. Slide eight gives the one message for the quarter. Slide nine sets out the two escalations, a quarterly check on 38 key trades and board sign off for fixed price contracts above $15M, and the next review date.

How to adapt this deck

A business outside construction should replace the incidents slide with the measure its regulator watches, such as complaints for a financial services firm or data breaches for a software company. A smaller company without a committee can present the same deck to its board, but should cut the escalation process slide and add one slide on risk appetite. If the register is longer than ten, keep the heat map to the top ten and move the rest to an appendix the committee can read before the meeting.

What risk guidance says

The ASX Corporate Governance Council's principles recommend that the board or a board committee review the entity's risk management framework at least annually to satisfy itself that it continues to be sound. Safe Work Australia's model Code of Practice on managing work health and safety risks sets out the duty to identify hazards, assess risks, control them and review the controls. This deck reports on both: the register and heat map for the committee, and tested safety controls.

What makes this deck work

Heat map and table agree

Slide three places each risk on a three by three grid of likelihood and impact, and slide four lists the same ten with owner, rating and trend. R1 subcontractor insolvency sits alone in the high, high cell and is the first of the two escalations, so the committee can follow one risk across three slides.

Controls are tested, not asserted

Slide six reports ten key controls tested this quarter with evidence for each, such as 60 height permits sampled and 120 inductions checked. Two are only partly effective, and both relate to the risks that rose, which is exactly the link a committee needs to see.

Safety numbers are read honestly

Slide five shows two lost time injuries over 488,000 hours, a frequency rate of 4.1 per million hours against 6.0 last quarter, and near misses up from 31 to 46. The deck reads the rise in near misses as better reporting and says so, rather than leaving the committee to guess.

Questions people ask

What goes in a quarterly risk review presentation?

A short summary of what moved, a heat map, the top risks with owner, rating and trend, results of controls tested, incidents for the period, how risks are escalated and what the committee is asked to decide. Nine or ten slides is enough, with the full register in an appendix pack.

Should a risk heat map be 3 by 3 or 5 by 5?

A 3 by 3 grid is easier to read on a slide and enough for a top ten. A 5 by 5 suits a detailed register in a document. Whichever you choose, keep the same scale every quarter so trends mean something, and label the axes on the slide itself.

How do I show risk trends to a committee?

Add a trend column, up, same or down against the last review, to the top risks table, and summarise the movers on the opening slide. A rule such as escalating any risk that rises two quarters running gives the trend a consequence the committee can rely on.

What does testing a control mean in a risk review?

Checking a sample of evidence that the control actually operated, such as permits completed or inductions done, rather than confirming the policy exists. Report the sample size and the result for each control, and link any partly effective control to the risk it is meant to reduce.

Who should present a risk review to the committee?

The head of risk presents the overall picture, and the owner of any escalated risk should attend to answer questions. Committees trust a review more when the people managing the risk speak to it, not only the function that maintains the register.

Can the heat map grid be edited after the deck is built?

Yes. The grid is a three by three matrix element, so cell labels and the risks listed in each cell can be edited directly on the slide. The matrix element also comes in two by two and SWOT forms if a simpler grid suits a different audience.
