Luca Calarailli is a veteran of the construction and architectural landscape who has spent years navigating the intersection of complex design and the rigorous technical demands of modern infrastructure. With a background that spans traditional craftsmanship and the latest technological innovations in the industry, he brings a unique perspective on the structural integrity of both buildings and the legal frameworks that protect them. In this conversation, we explore the often-overlooked nuances of excess liability insurance, a critical component of risk management that can determine the survival of a firm when catastrophic claims arise.
We delve into the misconceptions surrounding “follow form” policy labels and why assuming total alignment between primary and umbrella layers is a dangerous gamble for any contractor. Our discussion highlights the granular details that often slip through the cracks, from the specifics of “additional insured” status and defense obligations to the technical exclusions that can leave a project vulnerable to massive financial exposure. By breaking down the complexities of primary and noncontributory coverage and the logistical hurdles of per-project aggregates, we provide a roadmap for maintaining contractual compliance and protecting a company’s balance sheet in an increasingly litigious environment.
In the construction world, the phrase “follow form” is often treated as a safety net, yet you suggest it can be a significant trap for contractors. Why is this label so misleading, and what should professionals be looking for instead?
The primary danger lies in the assumption that an excess policy labeled “follow form” is a carbon copy of the underlying general liability coverage, which is rarely the case. In reality, every excess policy functions as a completely separate insurance contract with its own unique set of terms, conditions, and exclusions that can override the primary policy. When differences exist, the excess policy’s language takes precedence, which can lead to a “cascading” effect where each successive layer in the liability tower adopts the limitations of the one below it. This creates a scenario where a contractor might believe they are fully covered for a major claim, only to find that the upper layers of their insurance program don’t actually support the promises made in the lower layers. Instead of trusting the label, contractors must ensure their brokers are conducting a granular review of every umbrella and excess policy to verify that all contractual risk transfer provisions remain fully intact.
When we look at the specific requirements of a construction contract, “additional insured” status is almost always a baseline necessity. How do gaps typically form in this area when a policy moves into the excess layers?
While most follow form policies claim to recognize additional insureds that qualify under the primary policy, the fine print often introduces new hurdles that can disqualify upstream parties. Some excess insurers might narrow the scope of who qualifies, impose stricter qualification requirements, or even demand specific scheduled endorsements before they will recognize an additional party’s status. A common and devastating gap occurs within the “Other Insurance” provision, where the excess policy might state its coverage is only applicable after all other collectible insurance is exhausted. Without specific language that preserves “primary and noncontributory” coverage as required by the written contract, an excess insurer could argue that their coverage is secondary to the additional insured’s own personal insurance. This effectively undermines the entire purpose of the risk transfer, potentially leaving the contractor in breach of their contract with the owner or general contractor.
Liability isn’t just about paying out a settlement; it’s also about the legal battle that leads up to it. What are the common pitfalls regarding defense obligations and waivers of subrogation in these higher insurance tiers?
This is a critical area because the costs of defending a catastrophic claim can sometimes rival the settlement itself. Many contractors assume the excess layer will step in and handle the defense just like the primary insurer, but some policies only reserve the “right” to defend rather than the “duty” to do so. This distinction is massive; if an insurer has the right but not the duty, they can choose to stay on the sidelines, leaving the contractor to fund a multi-million dollar legal defense out of pocket. Similarly, subrogation waivers are frequently required in construction, but some excess insurers will try to preserve their right to sue responsible third parties regardless of what the primary policy says. If the excess policy isn’t specifically endorsed to follow the underlying waiver, the contractor could find themselves in a situation where their insurer is suing a project partner, violating the spirit and the letter of the original construction agreement.
Logistics and administrative details, like notice of cancellation and per-project aggregates, seem minor until a project is underway. How can these specific policy provisions create major headaches for a firm’s balance sheet?
These administrative details are the “silent killers” of contractual compliance because they are so easy to overlook during the excitement of a new project. For instance, most excess policies do not automatically include the 30-day or 60-day advance notice of cancellation that owners require, meaning the contractor must specifically request endorsements for every upstream party. Furthermore, the way “Per-Project General Aggregate” limits are handled can drastically change the amount of money available for a claim. While a primary policy might apply limits separately to each job site, an excess policy might consolidate those limits, meaning a single large claim on Project A could deplete the coverage available for Projects B and C. Contractors need to confirm that their excess program doesn’t restrict the number of per-project aggregates or the total limits across multiple sites, as failing to do so can lead to a massive uninsured exposure that threatens the company’s entire financial foundation.
Looking at the technical side of construction, there are several high-risk operations like XCU or EIFS work that often face strict exclusions. How do these technicalities manifest in excess policy wording?
Excess insurers often use proprietary manuscript forms that can introduce hidden exclusions for the very operations the contract was designed to cover. We frequently see exclusions for “XCU”—which covers explosion, collapse, and underground utilities—as well as restrictions on residential high-rise construction, products-completed operations, and exterior cladding systems like EIFS. If a contractor is working on a luxury condo or a complex underground infrastructure project, an exclusion for “residential construction” or “underground utilities” in the excess layer makes that policy virtually worthless for that specific job. Because these exclusions are often tucked away in the schedule of forms and endorsements, they can be missed unless the broker is looking for them specifically. A contractor might have a primary policy that covers these risks perfectly, but if the $10 million excess layer above it contains a project-specific exclusion, the firm is essentially self-insuring for any claim that exceeds the primary limit.
What is your forecast for the future of construction liability and the evolution of these excess insurance towers?
I anticipate that the gap between primary and excess policy language will continue to widen as carriers become more specialized and risk-averse in the face of rising litigation costs. We are entering an era where “standard” forms are being replaced by proprietary manuscript wording, which means the “follow form” label will become even less reliable than it is today. Contractors will likely need to invest more in specialized risk management expertise, as the technical complexity of these insurance programs now rivals the engineering complexity of the buildings themselves. My forecast is that we will see a shift toward more project-specific policies or “wrap-ups” to ensure consistency across the layers, as the traditional tower becomes too fragmented to manage safely. Ultimately, the firms that survive the next decade of claims will be those that treat their insurance policies with the same level of scrutiny they apply to their structural blueprints.
