Outdoor music venue site work advances; sinkholes remediated and foundations underway, project manager says
Summary
Project manager Tim Mattingly told the Elizabethtown council that earthmoving and foundational work at the planned outdoor music venue are progressing. About 60,000 of an estimated 250,000 cubic yards of dirt have been moved; two of three sinkholes on the property were remediated and a portion of footings for the stage are ready to be poured.
Elizabethtown ' City project manager Tim Mattingly reported substantial earthmoving and early foundation work Sept. 22 on the planned outdoor music venue, saying contractors have completed sinkhole remediation and are preparing to pour footings for the stage structure.
Mattingly, project manager with Congleton Hacker, presented recent site photos and a 3-D model to the council. He said crews have moved about 60,000 cubic yards of the estimated total 250,000 cubic yards of excavation for the project. Mattingly said workers remediated two of three sinkholes discovered on the property by injecting grout to cap voids and prevent erosion.
Construction activities under way or imminent include stage-area excavation, underground utilities and mechanical-electrical-plumbing work, mobilization of the steel contractor for stage siding, and footings preparation: roughly one-third of the stage footings were reported ready for pouring. Mattingly said block masons and masonry work should begin within about a month and that vertical construction will be visible once foundations are poured.
The project team is using building information modeling (BIM) coordination to identify 'clashes' (conflicts) among structural, mechanical and ductwork elements before field work begins, Mattingly said. The team is also conducting regular drone surveys using DroneDeploy to create up-to-date 3-D site models for planning and to estimate earthwork volumes.
Mattingly said the venue design includes a stage structure, a lower seating bowl, an upper lawn bowl, parking, an administration building, a concessions building and a restaurant building; he said the plan also includes landscaping with more than 500 native trees.
Why it matters: The update indicates the project is moving from mass excavation to foundation and utility work, with visible vertical progress expected once footings and masonry begin. The sinkhole remediation work resolved geotechnical issues identified early on, Mattingly said.
Questions and next steps: Mattingly told the council the team will continue weekly or biweekly drone surveys and provide updated site models at future briefings. Council members asked clarifying questions; the presentation closed with the project team noting more visible construction will follow the current foundation work.
