planning deliveries to construction sites

Projects often incur unnecessary costs because deliveries aren’t planned or coordinated.
These costs are as a result of:
1. trucks standing waiting to be offloaded because:
a. suitable offloading equipment is unavailable
b. the offloading area isn’t ready
c. there isn’t suitable access to the offloading area
d. the documentation, including risk assessments or lifting studies aren’t available
e. personnel required to offload are not available
2. materials being offloaded in the incorrect place requiring double handling to move them to the correct area
3. trucks are turned back empty because:
a. they are the wrong size or type of truck
b. the item isn’t ready
4. the delivery trucks are too big, or awkward, to access the site
5. trucks going to the incorrect delivery or collection address
6. the materials not arriving in the correct order, with the materials required first arriving last
7. materials arriving late
8. materials arriving too early resulting in them being double handled
