Can they actually raise the pinnacle to its final height without first completing the half section steel floors?


What an amazing progress. New Year’s top-out seems almost inevitable.

Nearing the 1/2 mile mark.

1 mile = 5,280 feet or 1,609.34 Meters

1/2 mile (1,609.34 divided by 2) = 804.67 Meters

804.67 - 780 = 24.67 Meters left to reach the 1/2 mile mark

To put the single stitched photo that I posted on Tuesday (post 13058) into perspective -

The posted photo is only 841KB, and 1228x6307 pixels, whereas the full size stitched photo is four times the resolution: 2455x12613 pixels.

The large version (not posted) was made from 8 individual photos, each of 2048x3072 pixels, totaling 14.1MB of data.

As you can imagine - the full size version with minimal compression is pretty spectacular. I'm tempted to straighten it out, take out a few of the flares, tidy it up a bit, and get it printed. Not sure what an acceptable pixel density would be for a print, but a six foot high print would work out to around 175 pixels per inch.

Apart from the stitching, no post-processing was performed at all. Equipment used is quite modest - a Canon 300D (I'd love to get a 50D, but can't afford one at the moment!), with a Sigma 70-300mm F4.00-5.6 APO DG.
Great tidbits on the details, man! Thanks for informing us of that. Yeah I also shoot with a Canon 10D and either a 50 prime or Sigma 70-300 f4.5-5.6 myself. Not a super expensive lens but the reach it has is incredible in the right circumstances. Would be great for BD!

Actually I believe I read that for the larger the print, actually the less amount of per-pixel sharpness you need since the image is so big. I think I've heard that 175 pixels/inch is plenty enough for a large print like that. That'd be great to have - though I'd have no place to hang something so big at my place haha!

Thanks again for the insight and all the work you've put into making the shots combine as well as they did.

To whom asked about the conspicuousness of such a large lens - sure, people will definitely notice you for sure and almost always assume you're a professional or doing an article for a newspaper or such lol! I've carried the 300mm around plenty of times and sure, it does create some attention but honestly I think at such a prestigous part of Dubai, people are used to seeing nice cars and all kinds of state-of-the-art tech and gear.

You might have security come up and inquire as to what you're doing but I don't personally see it as being "an issue" for the most part. Best to ask with people though just in case! We don't need our local photographers led out of The Address by security lol...

So guys do you really think a higher BD than 819m would look good?
This is my pic i edited. looks pretty good. the one on the right is about 850m tho. still looks awesome either way.

Thanks for the latest pics Imre.
Did anyone see how they installed the small section of Tier 27 to the pinnacle? Did they crane it up complete with the glazing attached? That would have been a interesting exercise for the crane operator to get it into location amongst all that structure. The next couple of sections below that will be even more difficult.

This stage by stage operation is really quite interesting to see!

As I posted yesterday they may jack 30m. and stop to install fins. Since all the fins are on there is no need to stop there. By the looks of the various angles (nice shots guys) every fin is installed.

It looks to me they jacked enough so tier 26 is just above the large temp. platform on top of section 22. They will surely stop and add the one small wing on tier 26 and clad it ?
Then jack untill tier 25 is exposed and stop to add the 2 small wings.
Then jack untill tier 24 is exposed and stop to add the 3 small wings.
Then jack to top out and add the 2 sections left of the second big(ger) wing of tier 22, the small wings of tier 22(1) and tier 23 (2), and connections to finish up.
There will probably be more stages but these are the major ones the way I see it - we shall see.

The top access platform still looks unfinished without the handrail and BMU monorail but perhaps I should stop flogging that dead horse ...

Here is some of OTR's shots:

- with some labels



- showing where the one small wing of tier 26 will go



It looks to me that approx. 6m. of tier 29 is above the top beams of section 23B. So 739.3 + ~6.4 + 21.3 + 1 (for the beacons) = 768m. or 2520 feet. Yet another fantastic new record in the history of man made structures.

Top out should be in Jan. '09.
Great time to be a skyscraper watcher/fanatic.

Hi all.

Hey Cul. in your diagram:
The wing just added to the pinnacle is the single wing of tier 26. Tier 27 starts with the roof of that wing as a terrace then continues up circular at 2.1m. dia.

Wow they added that wing fast. They must have them ready to go down on the podium.

Looks like my thoughts in my quote from around 12 pages ago are somewhat correct. They have jacked enough to put on the 2 wings of tier 25. I would say 778m. right now - but hey 780 sounds good to me as Cul has figured.

Here is a print showing where the 2 wings are on tier 25- the crane is at the bottom of the print. Remember the print is called tier 26 start because the roof of one of the wings is a terrace at the start of tier 26 then continues up with one wing. I am using it to show the shape of tier 25.



Here is my Tier Methodology to help with the complex arrangement of tiers and setbacks/terraces.

The_Tier_Methodology_of_the_Burj_Dubai.pdf (8 KB)

OK - I have discussed the issue of posting problems with the source of the new spire jacking plan. He says OK to post so here it is. Just as much info and detail as the original jacking plan we have but this is the latest revision.

Thanks source - you know who you are !!!

If the wings are all ready down below we may have top out toot sweet - perhaps before year end ?

So is that as official as it gets then?

796.7m to Tier 30, + 21300.0mm to the Pinnacle gives a total height of exactly 818m

796.7 is the start of tier 30 and the tier is 21.3 high.

Here is page one of my BD Plan ver. 4 to help show the top tiers.
