City presents third‑party peer review after police headquarters deflection discovery; AECOM pledges financial responsibility
Summary
A third‑party peer review identified structural issues at the new Fort Lauderdale Police Department headquarters and outlined repair steps. AECOM — the lead design/contractor team member — told commissioners it will pay costs tied to defects linked to its work and to monitor the building for five years.
A third‑party structural review of the Fort Lauderdale Police Department headquarters found multiple design and construction issues that contributed to roof and beam deflection and required foundation remediation, city staff and outside engineers told the commission on Feb. 18.
The city hired Weiss‑Janney Elstner & Associates (WJE) for an independent peer review after earlier corrective work and a stop‑work order in 2024 failed to resolve continuing deflection. WJE’s Phase 1 report — delivered in December 2024 — concluded that some roof cantilever and third‑story column elements were not code‑compliant in their original design and that earlier rectification efforts did not fully bring the elements into compliance. WJE identified repair paths including additional piles and pile caps at the foundation, and window‑wall design adjustments to accommodate predicted deflection over time.
Why it matters: Commissioners were shown modeling and monitoring plans intended to predict the long‑term creep (time‑dependent deflection) of the concrete structure and to ensure the building envelope and curtain walls are designed to accommodate movement without chronic leaks or ongoing moisture intrusion. City staff said many finish‑trade activities — chiller startup, generator installation, parking garage work — can continue in parallel with structural rectifications.
What the peer reviewers said: Brent (WJE) told commissioners WJE’s review divided the structure into roof beams, third‑floor beams, third‑ and first‑story columns and foundation, and that the roof cantilever beams and some third‑story columns were the primary concerns. He said roof spandrel beams on the north elevation showed code compliance, but some cantilever beams required additional analysis to confirm strength and deflection behavior. WJE recommended continued monitoring and permanent structural repairs where required.
Contractor and designer response: David Didier, AECOM’s east‑region chief operating officer, said AECOM will stand behind the project and “take full responsibility for paying the cost of the fix for what we’re responsible for.” He told the commission AECOM will continue monitoring the building for five years and address any issues linked to the deflection or the company’s work. AECOM representatives said they were preparing a written acknowledgement of that commitment to be incorporated in project agreements.
Monitoring & schedule: Thornton Tomasetti — the engineer of record for certain design packages — and AECOM proposed quarterly monitoring for 57 months (explained as 60 months from the original pour date). City staff said monitoring will include surveys to measure deflection every three months and that staff would explore independent verification surveys by certified surveyors.
Repairs and next steps: Pending WJE Phase 2 completion and city review, planned fixes described to the commission include micro‑pile installation, larger pile caps and added tie‑in work to ensure loads flow safely to the foundation. City staff said the project is roughly 80% complete in other areas and that an anticipated move‑in date was discussed for late 2025 but remains contingent on completing structural rectifications and obtaining required permits.
Budget and accountability: Commissioners pressed AECOM on a guarantee length and on financial responsibility for defects that appear during monitoring. AECOM said it will “stand by the building” and address work tied to the company’s design and construction responsibilities; AECOM also signaled it will discuss a lengthier warranty period beyond the initial monitoring window. The city and AECOM agreed to memorialize commitments in writing.
Context: The issue began in spring 2024 when in‑place monitoring and third‑party reviews identified unacceptable deflection in roof beams. A stop‑work order, subsequent monitoring, multiple peer reviews and supplemental design packages followed. WJE and other reviewers said that correct sequencing of fixes, attention to the window‑wall interface, and adequate foundation work are essential to reaching a long‑term solution.
What commissioners asked for: Commissioners pressed for written guarantees, independent monitoring, and clarity on who will pay for any remediation that proves necessary during the monitoring window. They also asked staff to report back with amended schedules and the written AECOM acknowledgement of responsibility that staff said they would present to the commission.
Ending: The city’s next steps are completing WJE’s Phase 2 work, finalizing repair designs with Thornton Tomasetti and AECOM, incorporating AECOM’s written commitments into the project record, and resuming targeted construction once permits for rectifications are in place. Commissioners said they would continue oversight until the building is returned to full, safe service.
