rary stair systems to maintain access for passengers, so that our crews and trade partners were able to make progress on the scopes of work and allow an early start date for the West Station House construction.” Loop Truss According to Krotkiy, Graham imple- mented an accelerated schedule plan that involved assembly of loop trusses on the ground subsequently placed in four successful major steel lifts during non-revenue hours (2:00-5:00AM) to reduce working time above the guide- way and minimize risks of service disruption. Each truss weighed 130,000 pounds and measured 250 feet long. To mitigate the impact of design changes on the project schedule, Graham implemented an accelerated schedule plan that involved assembly of loop trusses on the ground which significantly reduced working time above the guideway and minimized risks of service disruption.
