Is it necessary to store material or is it possible to distribute it to the place of use? Is the size of the component standard and easily transportable or does it need specialhandling? What is the required amount of material? How much is applied at once? Is it worth todeliver separated packages? Is it possible to place one onto the other? Which position it have to be stored in? (TheSITE PLANNINGsame as the ultimate position in the building.) How many packages can be stored ontop of each other? How many is reasonable to be stored on each other? Is the material sensitive for weather effects as wind, UV radiation, temperature, rain,moisture, etc.? Are there alternative materials to reduce cost and/or time?Vidovszky – BUTE – Department of Construction Technology and Management14
