Historic preservation projects are complex by nature. Every resource has a story, and every restoration effort uncovers new layers of history. Unforeseen conditions, hidden issues that surface during the dismantling process, can impact schedules, budgets and project success if not managed properly. 

Christman’s Historic Preservation Group specializes in anticipating these challenges. Unforeseen conditions are part of the job. The key is how you plan for, adapt to, and navigate through them. 

Common unforeseen conditions in preservation 

Unforeseen conditions often include: 

  • Hidden structural damage concealed or under finishes or behind prior modernization/restoration campaigns 
  • Regulated or hazardous materials such as asbestos, lead paint, or corroded piping 
  • Unknown modifications made over the resources’ lifecycle that were never documented 
  • Environmental factors such as water infiltration, freeze thaw, soil settlement, or invasive vegetation 

These surprises can pose real risks—but they don’t have to derail a project.  

Our approach: Planning, flexibility and communication 

1. Proactive investigation

Before work begins, our team conducts detailed assessments to anticipate risks. This allows us to create contingency and preservation plans, allocate resources strategically, and minimize potential disruptions once construction is underway. 

2. Flexibility and creative problem-solving

Every historic building/monument/and resource is unique. When the unexpected arises, our teams respond with creative, project-specific solutions that keep work moving forward while respecting the historic fabric and adjacent conditions. 

3. Transparent communication

We maintain open communication with all stakeholders, including owners, architects, conservators, consultants, and trade contractors. By fostering collaboration and trust, we ensure that decisions are made quickly and transparently, with everyone aligned on the path forward. 

Preserving the past, preparing for the future 

While unforeseen conditions are often unavoidable in historic preservation, they don’t have to compromise success. With proactive planning, adaptability, and collaboration, projects stay on track and historic structures are preserved for future generations. 

At Christman’s Historic Preservation Group, we bring the expertise, experience and commitment needed to manage the unexpected with confidence.
