745 m² of TRIO panel wall formwork per lift
in one core pour
Following the demolition of the existing building, Expanded Structures Ltd have won the concreting for an eight storey steel framed office development on Bothwell Street, Glasgow.
Despite its steel shell, there was still a challenging RC element to the project in the form of four, 10 storey cores. The largest of these required a stagge-ring 745 m² of TRIO panel wall formwork to form three lift shafts, two stairwells and adjoining corridors. Internal shaft formwork utilised the TRIO TSE shaft element to allow it to be struck and removed in a single crane lift.
This contributed to an impressive turn-around period of under ten days for the large central core.
Expanded Structures Ltd used CB 240 jump forms with trailing platforms on all four cores and chose to have them pre-assembled at the PERI fabrication facility in Rugby. For the handed east and west cores, CB 240 platforms were fabricated to the specifications of the west core and then, once the core had been completed, were returned to the fabrication facility to be modified for use on the east core.
“We used the PERI CB 240 climbing scaffold in conjunction with TRIO panel formwork to construct a number of concrete cores on this project in lifts of typically 4.50 m. The system exceeded our expectations in terms of both program constraints and the inherent safety feature demanded by us.”
