Oran Pre-Cast proposed a precast concrete frame as a viable alternative to the cast in situ RC flat slab design
|CLIENT||Grangegorman Development Agency|
|ONSITE DURATION||10 weeks|
The building is framed around 2 irregular shaped internal courtyards, intersected at an angle by a 3 storey administration block.
This geometry resulted in a high number of bespoke precast elements, with very little repetition between members. Rectangular, half-filled composite, spine and edge beams were all used as required.
Points of interest include:
Cantilevering floor slabs
Feature 8m long stairs
Beams of over 14m in length
Lattice floor with circular rooflight openings
Service openings provided in downstand beams and
Over 400 individual production drawings
The prestressed hollowcore flooring allowed for greater spans than a similar RC slab. This reduced both the number of supporting columns required, and the overall dead load onto the foundations.
