Shimmick/FCC/Impregilo (SFI JV)
McNary Bergeron is providing construction engineering services, including design of the temporary works and development of the erection procedures required to complete the heavy lifting/lowering of a 1200 ton movable scaffolding system, a specialized piece of construction equipment used to build the high level, cast-in-place approach spans. We are also designing dual purpose, modular steel falsework towers for construction of the 2000 foot cable-stayed mainspan. The 200 foot towers function both as an elevated work platform during heavy lifting of the 500 ton section of structural steel framing erected initially and as stability towers, to anchor the cantilevered backspans, during subsequent portions of the construction sequence. Main span steel erection is unique on this project, and McB has provided specialized never-before-seen equipment to assist in manipulating the bridge geometry and allowing for completion of field splices.
