Tools

2 impact drivers, 4 chargers, 6 batteries(previously 2ah but bigger are mote available now) a ratchet, 3 correct size sockets with impact . 2 channel lock style pliers big enough to grab wing nuts.

2x4s with little parts of 2x4s with 45 degree angle to prop up the dome to make it so people don't have to hold it all the time. These can fall and could bonk someone if it is not being held, ensure it does not fall on people.

member construction

Drill bit drill cuttoff wheel, measuring tape, press to squish the member ends flat, flap disk or grinder to deburr.

bolt specifications head size uses x socket

5/8 head. no more than .25in shoulder

Labor

A small crew is normally dedicated to this task. It normally takes about 2 days.

Roles

• Supervisor -- stands and watches
• Impactor
• Pattern layer this person preps the poles for the next stage and helps make sure the pattern is followed
• Nut holder -- this person holds the wing nut with a pair of pliars
• Lifter, 1 or 2, holds the

It is easier to connect pieces at waste height. so pattern layer will loosly get bolt on a step ahead of the snuggers while there is slack, and then the lifters can align and pull things together at waste height, then weight can also go on the new member right away allowing easier lifting.

We order the members so that when we disconnect things the lower ones can come off first. so when we are putting things up the bolt stack is: the ones going to a higher level are closer to the bolt head, and the horizontal ones are closer to the wing nut. then when the next layer gets added

Slack and play is sometimes nice, we go back around and zap the bolts with the impact.

We add tarps before the thing gets too high.

Safety

This may not be a complete list. 

• Ask questions, see something say something.

• We have deburred conduit, but there may still be sharp things.

• Team lift, communication and coordination of the team is important.
• Closed toe shoes recommended
• safety glasses are required.
• rough housing is not allowed.

• hearing protection is required when impacting. Impact drivers are very loud. It is important to have earplugs on strings because they get removed and put back a lot. Communication is easier without

• Do not put yourself under a part of the dome that is propped up.
• Take frequent breaks.
• You may want to wear gloves.
• Drink penty of water.
• Wear sunscreen.
• Have a big brimmed hat.
• snug fitting long sleeve clothes recommended for sun protection
• less flammable (cotton) clothes if using an angle grinder. or cut off

Techniques,

We start at the top and do a layer at a time. We leave the layer finger tight that is being attached to, and impact before it gets too high.

Try not to layout the pattern more than one level ahead.(in a way that confuses the lifters)

As they dome gets heavier, we have to prop up a side of the dome to be able to attach the next layer.

complete Triangles on the base can be used as a support. do not leave a single stick dangling down.

Starting a layer means tipping the dome.

Management techniques -- this is all about finesse, make sure the dome is liftend and the change is gradual.

You'll bolt

Last layer

The bonkers can push the whole dome over. Make them be as vertical as possible.

Slug trail is very dangerous, it also puts a movement force on the dome.

We need about 6 or 7 people at times to help lift and control shifting. Bonkers must be verical.
