Planning day today. Tony is not on site so I spent the day cleaning up and planning the roof build. Although the roof panels come in sizes that are manually handleable I have been thinking of putting together a set of panels (probably 4) and gluing and screwing them together with the locator beams in place making a large panel (2440 mm x 4441 mm) which can be lifted into place by the crane. David had a good idea, screw temporary location pieces into place to locate the panel into the right place.
More clearing up and chasing suppliers.
