8.11 Programme for hotel building
Precast crosswall frame and steelwork to first floor
An elevation of the hotel block is shown, indicating the ground floor and mezzanine
retail area with the six-storey hotel above the transfer floor level. The low-level area con-
tains three floors of bedroom units with three further floors forming the high-level unit.
A draft pre-contract programme is shown which includes the steel frame and trans-
fer floor for the retail unit, together with the crosswall construction for the hotel.
The cycle times for the erection of the precast crosswall frame per floor:
Low-level frame: - 9 days per floor
High-level frame: - 7 days per floor
Based on the bar chart programme sequence, an overall construction period of 78
days has been assessed for the complete hotel block. This includes a 30 day period to
construct the steelwork and the transfer floor to the retail area.
An extract from the project programme prepared by the project manager is
shown. This includes the mobilisation and removal of the tracked crawler crane on
completion of the work, an overall programme period of 94 days.
The construction of the crosswall precast frame was a complex operation due to
four suppliers being involved in providing the precast components. This involved
preparing a daily schedule of precast unit deliveries from four suppliers. Daily pre-
cast delivery schedules were prepared for each floor and just-in-time scheduling
applied.
