Construction of the Tate & Lyle Sugar Silo at Huskisson Dock, Liverpool from its early stages through to near completion. Workers construct a wood and steel framework, which is then filled with concrete to create huge arches that form the roof of the silo. As each section is completed, cranes and pulleys move the framework along so the next section can be made. Includes aerial views of the site during building work and shots of workers on top of the silo during its construction.
