Hybrid Greener RC Frame Choice

On this project the site boundary is the building boundary. To complicate building construction further two elevations, south and west, abut immediately to existing buildings.

At a very early stage of the tender the contractor decided to change the designed 10 storey in-situ RC frame to a hybrid concrete frame.

By changing all the vertical in-situ RC structural support elements (core walls, columns and stairs) to precast prefabricated off site elements to twin wall core walls and PCC columns and stairs and leaving slabs RC in-situ.

By doing so the environmental, community, carbon footprint impacts have been remarkably reduced and improved. They are now only lifting in precast off site elements into position. This has meant reducing site deliveries, less storage and double handling of materials, less impact to our community, improving workforce safety and less work at height activities potential incidences.

There is less deliveries to site resulting in a reduction of energy consumption and carbon emissions. This offsite hybrid frame frame build adopted has brought simpler logical build to the project and has also improved the quality and frame programme.
