52 Existing building structureThe typical floor slab to the existing building is of clay lsquohollow potrsquo construction 250mm thick spanning 55m between internal downstand beams supported on a double line of internal columns and columns in the faccedilade The building sets back at 7th floor level to create an accessible terrace and again at 8th floor with the introduction of downstand transfer beams on main column lines A transfer beam also exists at 1st floor level to support the columns in the faccedilade over the shopfront to High Holborn

The stability of the building provided by in-situ reinforced concrete shear walls around the stair and lift core and possibly additional shear walls formed of brick around the perimeter of the building The building is supported on shallow foundations Internal walls were originally of brick construction and the faccedilades are also of brick construction but clad in Portland stone

The existing buildingrsquos concrete frame has been retained and strengthened where necessary to support any additional loads proposed by the new scheme

53 FoundationsPiled foundations comprising 450mm diameter piles have been provided to support the new stair and lift core and the rear extension columns The piles have been constructed as rotary bored piles taken down to suitable bearing strata and have been co-ordinated with the boreholes required for the Ground Source Heat Pumps

54 Superstructure frameThe structure of the rear extension and top two floors comprises a steel frame with a shallow beam concealed largely within the depth of the precast concrete slabs Strengthening works were required to a number of the existing columns in order to support the additional load from the rooftop extensions Stability to the refurbished and extended building has been provided in the form of reinforced concrete shear walls around the stair and lift core Floor slabs to the stair and lift core comprise reinforced concrete flat slabs All structural members have been designed to the relevant codes of practice using the loads as defined above All structural steel sections have been grade s355 steel

55 Roof slabsThe roof to the rooftop extension comprises a shallow steel beam concealed within the depth of a lightweight timber roof structure whilst the roof to the rear extension comprises a shallow beam concealed largely within the depth of the precast slabs similar to the floor structures Roof plant at roof and 7th floor is located on anti-vibration mounts
