Turner used a traveling formwork system that enabled its crews to save significant time and labor.
An innovative traveler system was used at Capitol Hill light-rail station by Turner, which self-performed the project’s concrete package.
The system allowed Turner to travel the entire length of the station box, pouring concrete in complete areas. The design team believed eight pours would be required per section to get from the ground level to the roof. The traveler system enabled the team to reduce the total number of pours from 216 to 108, with the truss system spanning the station interior and pouring walls on both sides simultaneously.
This innovative system resulted in time savings by using a five-man crew for a scope of work that would traditionally need a peak crew of 12 men. The system also eliminated the need for shoring towers, allowing other trades to work unencumbered.
Ultimately, over 29,000 cubic yards of concrete were placed by Turner’s crew. The formwork system significantly decreased the project’s schedule and cost while increasing safety and efficiency.
