The foundations are direct with a raft slab which is also the bottom slab. • For reasons of compatibility between construction methods and acting as a strut some levels of slabs were built top down. • The roof is slanted and presents different inclinations in order to adapt to the complex morphology of the terrain.

At a temporary phase the slabs were partially completed to support the walls, allowing the excavation of these floors. These slabs are supported by temporary metallic columns which in the final phase are embedded in the concrete columns. | Premium Hotels Designing the future WORLDWIDE

International Iberian Nanotechnology Laboratory

Braga, PORTUGAL 2008 Major constraints arising from the site location and design loads Very demanding vibration limits due to the existence of high precision equipments; High values of imposed loads where taken for the design of slabs (7.5 kN/m2 to 22.5 kN/m2); Adoption of materials compatible with the requirements of electromagnetic interference; Due to the equipment lay-out and architectural constraints, large spans and limited column positioning had to be adopted in the design; Reduced soil bearing capacity and water level above basement level.

Construction Methodology Office & Lab Wing - Due to its large plant dimensions (200m) without having bilateral movement joints, a set of constructive joints and a lower ratio of W/C in the concrete composition where adopted in order to minimize the shrinkage effect. Clean Room – The pouring of the 2.0m height raft slab was object of special attention both in the composition of the concrete and in the process of concreting.
