  • Big moves in Baton Rouge. 🚧🏗️ This 130‑foot, 60,000‑pound truss was set in just 7 hours to form the North Porte Cochere entry at Bally's Baton Rouge Casino. With only three foundations and a 1‑inch tolerance, the lift required absolute precision. After five crane plan revisions, the team successfully executed the installation using a 400‑ton crane, navigating tight site constraints and active underground utilities. A great example of what thoughtful planning and strong field coordination can achieve. Kudos to Brett Buscher, David Montenegro, Pat Kerrigan, and Nicholas Wroten for coordinating this effort during the scheduling and design process. 👉 More about this project on the comments.

  • #ConstructionSafetyWeek 🚧| At W.E. O’Neil, safety is a shared responsibility. During Safety Week 2026, over 4,100 trade partners and team members came together across jobsites and offices to reinforce a culture of planning, ownership, and accountability. From leadership insights to hands‑on training, we continue raising the bar on construction safety as we work toward a zero‑injury workplace.  Safety Week sessions focused on what matters most—from the “Fatal Four” and heat prevention to the safe use of tools and equipment—ensuring everyone goes home safe, every day.  👉 Read more about Safety Week 2026 on the comments.  - 🔹 Did you know? 📊 According to the U.S. Bureau of Labor Statistics, fatalities due to falls, slips, and trips decreased by 4.6% in 2024 (from 885 in 2023 to 844 in 2024). Construction and extraction occupations accounted for 370 of these fatalities. Exposure to extreme environmental heat slightly increased from 19 in 2023 to 24 in 2024. https://lnkd.in/gVV66ZYv #ConstructionSafetyWeek #SafetyFirst #WEOwnSafety #EmployeeOwners #SafetyCulture

Through an extraordinary network of dedicated volunteers, CCA has become the largest marine conservation group of its kind, working to ensure healthy marine ecosystems while preserving access for recreational anglers.
