The workers strewn these panels out onto the public road when they are delivered, presumably due to the lack of space within the site perimeter. There were chatter about a car doing a U turn and knocked a whole bunch of them over. The workers then just bend the crooked panels back with bare hands (obviously still crooked) and install them on like it's none of their business. The panels on the lower portions of the tower have these visibly huge dents / holes / puncture wounds in them, when they crane lifted materials to the higher floors, it must have swung and hit the cladding hard. There are now talks of whether to repair the damage or not, someone from Ping An suggested hiring construction workers from Japan to do said job.

They build one of the hughest buildings on earth and than make savings on the cladding? Take japanese workers to fix it? What's that for a weird strategy

Ping an center was always a very cheap tower for its size with official cost of somewhere around 600-700million dollars, by comparison Shanghai tower costed more than 2.4 billion dollars.

Interesting... Is Wuhan GC the most expensive supertall? Abraj Al Bait is a complex of many buildings, I don´t know how to find how expensive was the main tower. Marina Bay Sands is also complex of 3 towers... So Wuhan GC is at the moment the most expensive supertall?

Wow I would've thought Shanghai Tower would be more expensive than at least Beijing Zun or Tianjin 117, with the curtain glass wall and everything... what makes them so much more expensive? Beijing one almost double the price!

Beijing and Tianjin are in an earthquake region, Shanghai (or Shenzhen) is not, so every building is more expensive there, for the same design and size (and the price gap go even higher for very tall buildings)



It is one of the reason why even if the land price is very high, Tokyo is not exactly bursting with very tall buildings (except for the 2 Tv Towers) and most tall buildings are "stumps" around 200m.

yeah, seems reasonable, but that still doesn't explain the highest price tag of the WGC, when Wuhan is in the lowest concern zone... maybe the three directional protruding floorplan construction type and quality is more expensive than earthquake etc. insurance and even security implementations. But then Burj Khalifa and Kingdom Tower are of a very similar floorplan...
So one would have to get insider information on the construction costs and financing i guess.
Wuhan doesn't seem to have such nice Skyscrapers on average, mostly residential highrises that don't appeal to me, but maybe it deserves such a feat.

Funny since Shanghai always seems to be top notch in terms of quality in the average skyscraper, but Shenzhen and Guangzhou really surprised me - especially Guangzhou has some very nice designs that seem top quality, at least from a design point - the IFC is one of the most beautiful skyscrapers imho. And they don't even have had a more expensive skyscraper than this one. But for the Greenland company the high cost is of course not something they aim for .

Is not the construction itself that cost so much, but all the "GREEN" aditions.

Of course Shanghai Tower also have some energy saving features, but probably WGC will have even more and more expensive.

Quote:
some of the planned sustainable elements of the project include:
• Energy recovery using an enthalpy wheel integrated into the ventilation system; this captures energy from the building’s exhaust systems and uses it to pre-heat or pre-cool air entering the building.
• A greywater recovery system, which takes waste water from the hotel laundry, sinks and showers and reuses it in the building’s evaporative cooling system.
• A high-efficiency lighting system, which uses low-energy-consuming ballasts and lamps to reduce required power consumption.
• A daylight-responsive control system, which automatically turns off electric lights when sufficient daylight is available.
• Water-conserving low-flow plumbing fixtures, which reduce the total amount of potable water required as well as the associated pumping energy.

Great find! Note that the $1.6billion mentioned in the doc is the contract money paid to CSCEC3 alone, it did not provide detail on what it entails. Most searches on the net quotes that the Greenland project investment exceeds 30 billion yuan.

That is basically the construction costs for the development area. Significantly less for the tower itself.

The 'foreign' architectural and engineering design fees are not significant because most of the work (practically all) will be handled by the general contractor cSCEc.

but the doc did not go into specifics as to whether that contract amount include the sourcing and manufacturing of all the input materials? "Contracting" in that region may not carry the same meaning as you interpret it to be though. "Basically the construction costs" is also to much of a sweeping generalisation. Although Greenland itself does not announce the numbers, 3rd party news did quote them with an "over 30 billion yuan investment into the tower".

Procurement arrangements

2. Which are the most common procurement arrangements if the main parties are local? Are these arrangements different if some or all of the main parties are international contractors or consultants?


The main parties involved in a project are:


•Owner/developer.
General contractor.
Architect/designer.
•Certified surveyor.
•Project management company.
•Certified project supervising agency (the role is primarily to represent project owners for ensuring the contractors' materials and workmanship are in accordance with design specifications and mandatory national construction quality standards).
•Chartered quantity surveyor (responsible for carrying out estimates and measurements of construction work progress, and verifying bills of quantities submitted by the contractor).
•Owner-designated subcontractors (such as interior design and decoration companies, landscaping contractors, and so on).
Material suppliers and subcontractors engaged by the general contractor.


In the residential and commercial real estate sectors, an owner usually enters into separate contracts with a design institution and a general contractor. Under this method, the owner retains a designer to design and produce tender documents on which prospective general contractors will bid, and then enters into a build-only contract with the chosen general contractor.
