Understanding your Total Cost of Risk (TCOR)
Effectively managing risk on a large-scale development project requires more than simply securing coverage—it demands a strategic, forward-looking approach. Developers face a wide range of exposures throughout the project’s life, routinely necessitating insurance for construction liability, property damage, surety and subcontractor default, and specialized risks, such as weather, environmental conditions, and site- or project-specific challenges.
Yet too often, developers underbudget or underestimate the true scope of insurance-related costs. Some account only for core policies, like Builder’s Risk or General Liability, without considering the full suite of coverages that may be needed or prudent to buy. Others only look at the coverages held by one party, such as the contractor or developer, without realizing the need to assess all parties involved and what each line of coverage protects.
This piece sets out to clarify what comprises a project’s Total Cost of Risk (TCOR) so developers and their capital partners can plan accordingly.
What is TCOR?
TCOR represents the full financial exposure tied to insurance and risk management for a development. While this figure includes insurance premiums, developers must also consider policy deductibles, potential uninsured exposures, risk control investments/requirements, and more.
Understanding your TCOR offers a clear picture of what it truly costs to manage and mitigate risk. It supports informed decision-making, strengthens lender and investor confidence, and helps avoid funding gaps or last-minute surprises.
Importantly, TCOR should not be treated as “set it and forget it.” Insurance budgets are often developed 12–24 months before construction begins, but much can change:
- Insurance market conditions may shift
- Catastrophic weather events may impact premiums
- Project scope or cost basis may evolve
- Lender insurance requirements may change
For this reason, we recommend revisiting and reassessing the project’s TCOR at least quarterly—especially on large-scale or CAT-exposed developments. A proactive, comprehensive risk strategy helps ensure both adequate protection and cost efficiency throughout the life of the project.
The Breakdown
The following outlines key insurance coverages and associated considerations that contribute to a project’s TCOR—whether placed by the owner, contractor, or another involved party. Regularly reviewing these policies, including those maintained and charged by the general contractor, is essential for helping ensure adequate financial protection and a well-balanced risk strategy.
What’s not reflected in the visual, but is equally critical, are the underlying conditions and compliance obligations within the policies themselves. These may include site-specific requirements (e.g., security measures, lighting, fire protection systems) that, if unmet, could restrict or even void coverage.
In addition, deductible obligations in the event of a loss, often as high as 5% of the project’s insurable value, must be clearly understood and budgeted for, including clarity around which party bears responsibility for payment. Finally, in addition to the “big” project-level policies placed by the developer or contractor, all contractors and subcontractors are required to carry their own coverages (e.g., Workers’ Compensation, Auto Liability). These costs are typically passed through the GMP, and while often embedded, they represent a meaningful component of the project’s overall Total Cost of Risk—and should not be overlooked.
