Executive Summary
A representative Florida Milestone Inspection was performed to evaluate the structural condition and long-term performance of a coastal parking facility following reported deterioration and recurring moisture intrusion. The assessment distinguished cosmetic wear from functional deficiencies, documented concrete cracking, spalling, and joint deterioration, and identified corrosion risks associated with chloride exposure. Findings guided targeted remediation planning, supported statutory compliance under Florida Statute 553.899, and established engineering priorities for phased rehabilitation, and positioned Owner’s Representative Services and QA/QC Support as logical next phases during restoration.
Situation
- The condominium association initiated a representative Florida Milestone Inspection to evaluate the structural condition, waterproofing performance, and long-term reliability of an integrated parking structure following concerns regarding recurring moisture intrusion and visible deterioration.
- The assessment included structural evaluation, drainage review, deterioration mapping, repair prioritization, and capital planning to support statutory compliance and long-term asset management.
Prema's Approach
Prema Consulting Group conducted a comprehensive milestone inspection tailored to parking structures:
- Visual and tactile inspections of double tees, inverted tee beams, spandrel beams, columns, diaphragms, and expansion joints.
- Assessment of waterproofing assemblies, drainage systems, traffic coatings, and exposed reinforced concrete.
- Documentation of deterioration mechanisms such as chloride intrusion, reinforcing steel corrosion, and connection distress.
- Development of a repair prioritization matrix aligned with statutory requirements and owner priorities.
- Evaluated deterioration affecting traffic-bearing slabs and parking structure framing while considering operational impacts and opportunities for phased rehabilitation that minimized disruption to facility users.

Observed conditions
- Concrete deterioration: Concrete cracking, spalling, and localized delamination affecting structural durability and long-term serviceability.
- Corrosion: Evidence of reinforcing steel corrosion associated with chloride intrusion and prolonged moisture exposure.
- Joint deterioration: Expansion joint failures leading to water infiltration and differential movement.
- Drainage deficiencies: Drainage deficiencies resulting in ponding and accelerated deterioration of traffic-bearing surfaces and supporting structural components.
- Connection distress: Localized distress at structural connections requiring evaluation to determine repair priorities and long-term performance implications.
Repair Strategy
Prema developed a phased rehabilitation program:
- Immediate repairs: Stabilization of distressed connections and replacement of failed expansion joints.
- Short-term repairs: Complete concrete restoration, waterproofing improvements, drainage corrections, and localized corrosion mitigation to slow ongoing deterioration.
- Long-term repairs: Implement phased rehabilitation of parking structure framing, traffic-bearing surfaces, waterproofing systems, and corrosion protection measures to extend service life while minimizing operational disruption.
- Capital planning: Integrate repair priorities into phased capital improvement planning based on structural significance, anticipated service life, operational impacts, and available reserve funding.
Conclusions
The milestone inspection confirmed that the parking facility exhibited deterioration requiring immediate and phased rehabilitation. The engineering evaluation also established a practical framework for phased rehabilitation that balanced life safety, operational continuity, and long-term asset preservation. By addressing structural deficiencies proactively, owners can ensure compliance with Florida Statute 553.899, protect public safety, and extend the service life of the facility.
Why This Matters
Parking structures in Florida’s coastal and high-moisture environments are vulnerable to chloride intrusion, corrosion, and water infiltration. Milestone Inspections provide owners with evidence‑based clarity on structural performance, separating cosmetic wear from functional deficiencies. They deliver actionable engineering insights that guide remediation planning and capital investment decisions, while repair strategies reduce risk, reinforce reliability, and extend facility life.
