Expert Subcontractor Default Insurance Claims Consulting (SDI)

Trustworthy SDI Claims Evaluation by VERTEX

VERTEX has been a trusted partner to the insurance industry to investigate and analyze environmental, construction, and surety related claims for nearly three decades. It is because of this that our insurance clients also utilize VERTEX’s expertise to evaluate Subcontractor Default Insurance (SDI) Claims to help minimize lost time and productivity on construction projects.

Minimizing Project Time Loss

VERTEX’s experienced claims consultants understand that subcontractor defaults can have significant impacts on projects. By engaging with carriers early in the process and setting the insureds expectations, VERTEX is able to help mitigate common pitfalls which can impact timely outcomes. VERTEX’s analysis includes reviewing the terms of the policy, the Proof of Loss, the subcontractor’s scope of work and evaluating the direct and indirect costs associated with the default. VERTEX’s ability to address the multitude of nuances that occur as part of the SDI claims process is supported by specialists in construction accounting, scheduling, and fault allocation.
