Building Conditions Assessments

Informed Decisions Start With Knowing What You’re Working With

​

Historic and aging buildings rarely tell the full story on paper. Our Building Conditions Assessments provide owners, agencies, and design teams with a clear, field-tested understanding of a building’s existing condition—before scopes are finalized, budgets are locked, or risk is unknowingly accepted.

​

Treeline Construction approaches assessments from the perspective of a contractor who will ultimately be responsible for executing the work. That means our findings are practical, constructible, and grounded in real-world conditions—not theoretical assumptions.

​

What We Assess

Our assessments are tailored to the building, its use, and the client’s objectives, but typically include:

​

• Structural Systems

  • Foundations, framing, lateral systems, and observable seismic vulnerabilities

• Building Envelope

  • Roofing, siding, windows, doors, waterproofing, and moisture intrusion

• Interior Conditions

  • Finishes, concealed deterioration (where accessible), and prior alterations

• Mechanical, Electrical & Plumbing (Visual Review)

  • Age, apparent condition, and constructibility considerations (in coordination with licensed professionals)

• Life Safety & Code Triggers

  • Observations that may impact future rehabilitation or change of use

• Historic Fabric

  • Character-defining features, prior repairs, and areas requiring sensitive treatment per DOI Standards

​

How Our Assessments Are Different

Most condition assessments are written by consultants who won’t be the ones pricing, sequencing, or building the work. We bring a contractor’s lens to every evaluation.

​

That means we focus on:

• What can realistically be repaired vs. replaced

• Where hidden risk is most likely to emerge

• How access, sequencing, and site constraints affect constructibility

• Which issues will drive cost, schedule, or phasing decisions

• Where early intervention can reduce downstream change orders

 

This approach is especially valuable for historic buildings, remote sites, and occupied facilities where unknowns carry real consequences.

​

Deliverables You Can Use

Our assessments are not shelf documents. They’re built to support decision-making.

Typical deliverables include:

• Written condition narrative by system

• Photo documentation keyed to observations

• Identified deficiencies and risk areas

• Repair vs. replacement considerations

• Constructibility notes for designers and owners

• Budgetary guidance or ROM opinions (when requested)

• Input to phasing strategies and capital planning

​

When a Conditions Assessment Makes Sense

• Early planning for rehabilitation or adaptive reuse

• Capital improvement or deferred maintenance planning

• Pre-design support for architects and engineers

• Risk reduction before funding or procurement

• Historic preservation projects where scope sensitivity matters

• Occupied or logistically constrained facilities

​

Experience That Matters

We’ve spent nearly two decades working inside historic and high-consequence buildings for the National Park Service and other public owners. We understand how early decisions ripple through design, procurement, and construction—and how avoidable assumptions can become expensive problems later.

​

Our assessments reflect that experience and are grounded in:

• Real construction sequencing

• FAR-based project delivery

• DOI Standards for Historic Preservation

• Collaborative coordination with owners and design teams

A Smarter First Step

A Building Conditions Assessment isn’t about finding problems—it’s about understanding reality. When the existing conditions are clear, projects move forward with fewer surprises, better scopes, and stronger outcomes for everyone involved.
