Overloading due to inadequate design of supporting structures for supporting racks/frames

Damage to pre-cast elements

Damage to pre-cast elements

Storage area should be large enough for pre-cast components to be stored properly with adequate room for lifting equipment and for manoeuvring trucks, cranes and other relevant vehicles. Pre-cast components should not be stored directly on the ground. Generally, two discrete support points should be provided. Timber supports raised above the ground or dedicated racking systems should be used in all cases
