KLINE Wins 2025 PTI Award for Historic Surfside Project
Project:
Reviving Heritage – Surfside’s Journey from Historic Landmark to Luxury Haven
Award:
Post-Tensioning Institute (PTI) 2025 Award of Excellence
Category: Industrial or Special Applications
KLINE is proud to announce that our Reviving Heritage project in Surfside, Florida, was honored with the 2025 PTI Award of Excellence in the Industrial or Special Applications category. This award, presented by the Post-Tensioning Institute (PTI), recognizes outstanding achievements in the use of post-tensioning to solve complex structural challenges.
This remarkable project transformed a 1936 historic landmark, designated a historic structure in 2014, into a modern luxury residence while preserving its original façade and architectural charm. Our Principal, Layth Hussein, P.E., accepted the award on behalf of the whole design-build team, celebrating the collaborative success of architects, restoration experts, contractors, and engineers.
Sustainability & Preservation in Harmony
Sustainability was also a key driver in the structural strategy. By using PT systems, the team was able to reduce material use, minimize the carbon footprint, and enhance the building’s energy efficiency. The project exemplifies how structural rehabilitation and modern luxury can coexist with historic preservation when engineering and design come together.
A Model for Preservation-Driven Engineering
This award-winning project serves as a model for what’s possible when engineering innovation, historical preservation, and sustainability are approached as a unified goal. Seaway Villas now stands as an inspiring example of how creative, technically advanced structural design can honor the past while serving the needs of the present and the future.
Post-Tensioning Innovation & Structural Challenges
The project required innovative structural solutions, especially in the use of hybrid post-tensioned concrete systems. These systems were instrumental in:
Preserving and relocating the historic façade approximately 150 feet to enable below-grade construction.
Eliminating interior columns to achieve open, flexible floor plans and uninterrupted views.
Integrating new floor systems with the existing masonry without compromising the building’s structural or historical integrity.
The team used post-tensioned skid beams to move the building safely, as well as PT floor slabs that maximized ceiling heights and supported modern layout demands while protecting the delicate exterior. These solutions required precision engineering, advanced modeling, and careful coordination with restoration professionals.
