While there were disagreements regarding the timetable and massive shortages of supplies, the project to build the complex broke ground in 1929 with the influx of thousands of idealistic Soviet workers. The American contractors were critical of the handling of the project and were frustrated by mismanagement and so the majority of the design ended up falling to the Soviets. Much of the failure to properly organize the construction efforts was due in part to the desired speed at which the Soviet government had laid out as a part of their Five Year Plan. Additionally, there were changes in personnel who had faced removal over political concerns that emerged over loyalty to the Communist Party.
