FOLLY CONSTRUCTION

Scaffolding connections - unresolved (20th August)

(1) Custom lengths: rather than cut down smaller lengths and connect using a standard sleeve coupler to the 3.5m pipes as we've indicated, it would be easier (cheaper) for scaffolding co. to use standard 0.5m lengths and somehow connect these to the 3.5m pipe in a variable way - is there a coupler that can do this?

Possibilities:

• would a swivel clamp work - connecting the 2 pipes side by side?

•  how much tolerance does the standard internal connector have?


(2) Connection to wood framing: need something that will connect a vertical pipe to a horizontal length of 4x2 timber. Problem: standard grip type couplers connect at right angles on same plane, but ideally we want the wood to sit above the connected pipe.

Possibilities: use the standard 'grip' like couplers and use a small piece of pipe/wood as connection between the 2. Or can we source something like this?:

FOLLY STRUCTURE DETAIL UPDATED (32 Aug) - timber details

The structure of the folly has no major technical issues, however, we still need to negotiate with the scaffolding company on how the timber framing attaches to the scaffolding, and how the end-joints work withthe shrink-wrap.


MEETING WITH UWE (12 Aug)

- no scaffolding people

- Uwe, Jenny/Rob, Daniel, Angela 

Our folly design did not present any major difficulties, only a few minor adjustments  (eg. additional bracing)

Lighting supplied for the folly = 5 fluorescent tubes linked directly to the street lighting grid (ie. not our generator) to illuminate the folly every night, plus as a deterent to vandalism.

• Additional lighting can be added but will be linked with event nights only.
• We said ideally we'd have 12 tubes for our folly (3 per folly segment) - need to confirm this request was also sent in writing (e-mail) via the mangement team

Standard scaffolding lengths: 0.5m to 6.5m, in 0.5m increments. Try to stick with these lengths to avoid cutting custom lengths. If we really can't do that, propose a solution where only small pipe lengths need to be cut (ie combine a long one with a very short one).

MEETING WITH SHRINKMASTER (15 Aug)

- Uwe, Shrinkmaster (names?), Jenny, Rob, Daniel, Angela, Dylan

PVC pipe may be a problem, mostly because of the long lengths we require: (1) may not hold up to tensions created by shrinkwrap (2) may be damaged by the hot air gun when shrinkwrapping
Suggested wooden battons instead, which we'll go with (2x4 lengths).

• Advantages:
1. stronger, more durable than PVC piping
2. can be cut to custom lengths and corners smoothed
3. fixing/connections may be easier (screws/nails/nail plates) and more reliable than PVC pipe connections, especially for the shrinkwrap connections (see below)
• Disadvantages - mostly that PVC piping is part of our scaffolding deal but the wood is not:
1. we'll probably have to fund the lengths of 2x4 ourselves
2. have to source & prepare (?) the wood, sand down corners etc on site on the scaffolding day

Shrinkwrap may pull outer folly edges inwards, they recommended strapping to connect each segment across the inner gap.

• NB. the strapping is pretty discrete so hopefully won't impact on the overall 'inner void' impression.

Each folly segment cannot use one entire sheet so will have separate sheets on inner faces. Since we'll now have wooden battons along the top they suggested a nice solution, which they showed us a photo of, for joining the wrap (bottom diagram):

• Smaller wooden battons will be used to wrap the shrinkwrap around then fix  rather than tape/ugly joins.
• will give a smooth seam at the edges of the inner faces.
• we'll probably also need to source these though need to confirm with shrinkwrap people, however, could use skillet stacking timber that could be grabbed for free (?) ie. 10mmx25mm

The shrinkwrap can extend down the container, as modelled - as only need a very small gap between the container and scaffold pipe (maybe only 5mm or so, just room for the shrinkwrap itself).

Overall, they thought our design will look pretty good and the curves should be as we modelled them...and then it started snowing outside so got a little distracted...
