Conventional overcasts can be labor intensive, expensive and time consuming. A possible alternative to this could be modular, re-usable structures. These structures should have the following characteristics:
- Lightweight and durable
- Easy to transport and assemble (no special tools required)
- Reliable and efficient
- Sturdy enough to resist rib rolls and minor roof material
When traveling over an overcast, slipping and tripping hazards can arise. Several manufacturers provide pre-manufactured designs of stairs complete with automatic stair tread adjustment to adapt to any overcast height. These units should include properly designed handrails and slip proof stair treads.
