Reinforced concrete, or rebar, is widely used by Harrow Industrial within multi-story constructions. These materials in modern construction are brought together to resist multiple tensile forces. Concrete is a relatively brittle on its own, so to increase its overall strength, steel rods, wires, mesh, or cables are embedded in the concrete before it sets. Together, the two materials combined, resist a variety of applied forces, effectively acting as a single structural element.
Shell and core is an early stage of a buildings overall construction, in terms of a preparing the building for fit-out. It refers to the installation of the overall structure of the building, which gives the 'shell'. This stage, otherwise known as the Cat A fit-out, brings the occupiable space up to a concrete only structural stage. The building is now ready for the Cat B development, whereby the internal fit-out can commence, including services, partitioning walls, flooring and decorating, ready for occupation.
Sometimes, a shell and core project will be fitted out to a Cat A standard, the scope of which varies between different developers, but typically a shell and core stage of the building includes the cladding, base plant, stairwells and communal areas, toilets, external works, receptions and lobbies, lift shafts, basements, car parking and loading bays.
Insitu concrete works will be carried out by our own specialist steel fixing and carpentry teams supervised by time served supervisors trained in these specialist techniques.
