Proj Overview

PROJECT OVERVIEW

In recent years, the developer has worked hard to establish West Palm Beach as a global business city. The first piece of their planned development puzzle was the Class A office structure, One Flagler. As part one of a large urban development strategy, the developer wanted a waterfront building that was sleek and modern and could also be constructed speedily.

PRECAST SOLUTION

The developer was very adamant about efficiency, speed, and quality. In light of these considerations, precast concrete quickly emerged as the façade material of choice.

Key Project Attributes

  • One Flagler reflects what that architect calls “the rich tradition of Florida’s tropical modernism,” presiding like a lighthouse over the entry to West Palm Beach at the Royal Park Bridge.
  • One Flagler spans 270,000 ft2 along the Intracoastal Waterway. Twenty-five stories high, with panoramic water and city views, the LEED gold-certified structure offers not only office space to its tenants but also fine dining, fitness, and conference facilities.
  • The trellis-like exoskeleton of One Flagler is unique in its depth, going far beyond the convention of a glass office tower, providing shade from the Florida sun on the entire surface of the façade.

Project/Precast Scope

  • Preglazed white architectural precast concrete panels with a burnished finish compose the building’s exterior façade.
  • The architect designed the panels to provide integral sunshade elements, with projections of 2 ft 6 in. and preinstalled 8 ft 4 in. × 10 ft 11 in. low-E insulated windows for ultra-clear visibility along with thermal performance.
  • The project team gave extra attention to panel joining, so that panel jambs and sills would tuck behind adjacent panels to conceal joints and create a more seamless appearance.
  • The project included 48 unique panel types. Most of the panels were double module units with double sills.
