Unless stone slabs or pre-assembled panels are erected directly from the truck or trailer, ample room will be needed at the job site to distribute them reasonably close to where they will be installed. They should be distributed so their identification numbers are visible.
Extra handling, moving stone at the job site certainly will increase the possibility of breakage or chipping.
Unloading of trucks or containers at the job site should also be done carefully. If a mobile crane is used for unloading, a permit is usually required. Forklifts are also often
needed to unload trucks or container shipments of stone products.
How to store stone on structural floors should also be carefully planned. Unpolished slabs
must be protected from possible staining. The storage areas should be adequate
in size, accessible, and the moving of other materials around them should be limited. Pre-loading floors should be
chosen in accordance with requirements set forth by the engineer of record.
Stone slabs can be stacked. But when being stacked, they should be separated with two non-staining skids placed approximately one-quarter of the way from each end of the slab. Skids should be placed directly above one another to prevent cracking or breakage.
Pre-assembly of stone on steel frames,
curtain wall components or precast concrete is done in a shop under controlled conditions.
If possible, pre-assembled panels should be shipped in a position similar to the one in which they will be installed. For supporting seats, the use of special hard rubber pads is recommended. It is prudent to protect the stone from possible staining during transportation.
All cladding stone above the first course shall have lifting holes
pre-drilled. Type and location of lifting holes shall be carefully designed for safety and clearly defined on the shop drawings or shop diagrams.
Try to avoid cutting lifting holes at the job site. All stones shall have identification numbers for erection purposes and shall be shipped and stored in the sequence of erection.
