How to make full use of modern gadgets
Use roll forming machines from which you can transport to the site in a specially modified ‘Mobile Fabrication Facility’ inside two 20-foot Shipping Containers. This is ideal for Greenfield or remote-access sites. If required, you can raise the Roll former up to roof-level, position it outboard of the gutter and roll form the roof at roof level. A crane at ground level lifts the coils to the Roll former. Other than hand signals use walkie talkies, designated signalers, radios to communicate one another in construction places.
