C.A.D.
- C - Coordination - greater need for interface with other contractors
- A - Accessories: more use of accessories, particularly receptor systems
- D - Drawings - more Reliance on shop drawings

CW and AW

Key areas objectives requiring coordination on commercial installations include (3):
DMC
Design Intent
Movement
Clearance provisions
A significant source of movement concerning commercial product installation is:
Thermal expansion.
Which of these materials experiences the greatest amount of thermal movement:
Aluminum Rigid PVC Glass Reinforced Polyester Wood Steel
Rigid PVC
In and 8 foot sample, about how much (maximum) movement would a 100 degree temperature change create for each of the following: Wood Steel Glass Reinforced Polyester Aluminum Rigid PVC
0.025” Wood
0.065” Steel
.140” Glass Reinforced Polyester
.130” Aluminum
0.44” Rigid PVC
