The exemplar project extensively utilized 3D modelling & BIM and was constructed within an 18 week on-site programme, giving a 14 week saving over an in-situ concrete solution.
The use of 3D modelling during the design process assisted in ensuring that the potential clash of structure with M&E services was avoided, as well as helping to determine the accuracy of connections and developing logistics and erection programmes.
Off-site precast concrete
Over 1500 precast concrete components, some weighing in excess of 20 tonnes, were manufactured in six different off-site precast concrete factories. Just-in-time delivery was co-ordinated to ensure a fast on-site construction programme was maintained.
The three stair and lift shafts that provide structural stability to the finished structure used a precast concrete box solution, rather than individual panels, enabling full height construction of these shafts including stairs and landings to be achieved in less than eight days.
Quality of finish
Hollow-core flooring units were used with an in-situ structural concrete topping, supported by DELTABEAM® Composite Beams to ensure minimal downstands
This ensured the ease of running M&E services and maximised ceiling-to-floor heights.
