Dive Brief:
- Clark Construction advanced major structural upgrades for the Metro system in Washington, D.C., within a 56-day sprint last summer.
- The Washington Metropolitan Area Transit Authority (WMATA) says the work at Bethesda and Grosvenor-Strathmore Metro stations was delivered on time and on budget.
- Improvements required specialized demolition, material removal, and track replacement, with a new mezzanine constructed at Bethesda.
Dive Insight:
- Following a 44-hour demolition in November 2025 at Bethesda, Clark Civil’s teams erected steel, applied fireproofing, and placed concrete within the station.
- The cost of the Bethesda mezzanine grew significantly, from an estimated $2.4 million in 2016 to $52 million.
- At Grosvenor-Strathmore, crews used remote-demolition robots to remove platform tile and concrete topping slab, replacing 1,200 linear feet of track edge.
- The contractor described the projects as "a unique puzzle."
