Key Takeaways
- Risk registers identify risks proactively with mitigation strategies.
- Create during planning, review weekly during construction.
- Resource calendars map subs to date ranges.
- Confirm subs 2 weeks ahead—most effective scheduling practice.
Risk management and resource allocation significantly impact renovation outcomes.
Building a Risk Register
Each risk: Description, Probability, Impact, Mitigation, Owner. Create during planning, review weekly.
| Risk | Prob | Impact | Mitigation |
|---|---|---|---|
| Hidden structural | Med | High | 15% contingency, pre-drywall inspection |
| Material delays | High | Med | Order long-lead early |
| Sub no-show | Med | Med | Maintain backup contacts |
| Permit delays | Low | High | Submit 3-4 weeks early |

Resource Allocation
Map subcontractors to date ranges. Confirm each 2 weeks before start—this is the single most effective resource management practice.
| Risk Event | Probability | Impact ($) | Risk Score | Mitigation Strategy | Contingency |
|---|---|---|---|---|---|
| Hidden structural damage | Medium (30%) | $5,000-$25,000 | High | Pre-purchase inspection, budget 10% structural contingency | Engineer on retainer; pre-negotiated repair rates |
| Permit delay >2 weeks | High (50%) | $1,500-$4,000 | High | Submit permits during due diligence; use expediter in slow jurisdictions | Begin non-permit work (demo, design) during wait |
| Subcontractor no-show | Medium (25%) | $2,000-$8,000 | Medium | Maintain backup sub for each trade; 48-hr cure notice in contract | Activate backup sub; document for back-charge |
| Material price increase >10% | Low (15%) | $1,000-$5,000 | Medium | Lock material pricing within 30 days of start; bulk purchase early | Material substitution options pre-approved in SOW |
| Weather delay >1 week | Medium (30%) | $700-$2,100 | Low | Build 1-week float into schedule for exterior work | Shift to interior tasks during weather delays |
| Failed inspection | Low (20%) | $500-$3,000 | Low | Pre-inspection walkthrough with trade; photo documentation | Same-day correction; reschedule within 48 hrs |

Common Mistakes to Avoid
Not maintaining a risk register for renovation projects
Consequence: Risks are discovered reactively rather than managed proactively, leading to higher costs and longer timelines
Correction: Maintain a risk register from pre-construction through closeout, reviewing and updating it weekly during active construction
Allocating the same contractor to multiple projects simultaneously without schedule coordination
Consequence: Contractor splits attention between projects, both suffer delays, and neither gets adequate supervision
Correction: Coordinate scheduling across projects so the contractor completes critical phases on one project before starting on another
