    Speaking as an architect with 25 years experience, I’ve done loads of pricing, tenders, quantity surveying, and have visited the Colosseum.
    I would say in todays money it would cost $2.5 - 3 billion to build a replica. The marble supplying and finishing would be by far the most expensive element. Then you’ve got the roof canopy, hypogeum machinery, arena decking, iron clamping, plant, scaffold, shuttering, it goes on and on.
    The new Wembley Stadium cost $1 billion 15 years ago. It’s a similar size to the Colosseum and holds 90k people. Obviously modern steel framed buildings are much more cost effective, otherwise we would still build everything out of concrete, brick and marble.

    Carpenter here: I think the wide range is an accurate estimate. It will all depend on how true to the original it would be. I think if somebody wanted to build something that was the same scale as the original but that used thin slabs of finished stone to clad, ignored all modern building codes, and used sculptures that were just plaster casts of existing statues, you could do it for $150m or less. But once you start adding in things like electricity, stair height limitations, guard rails, sprinklers, alarms, elevators, ramps, automatic doors, authentic travertine, hand-crafted marble sculptures, parking spaces, sewage systems, storm drains, insurance, gold decorations, hand-chiseled signs...well...sky is the limit in terms of price.

    While in Rome, back in the mid 70s, I decided to leave my hotel and "find" the
    Colosseum. I took the subway via the "B" line and got off at the "Colosseo"
    station. All of this I had to look up on recent City of Rome subway maps but
    what I remember as clear as the day Kennedy was assassinated was the absolutely
    jaw-dropping sight of the structure as it sits directly across the street from the
    subway station. Keep in mind that as the Colosseum exists today, much of it's
    outer structure (wall) is gone.... still, it is huge and (to me) beautiful. This was a
    fascinating video ... thank you.

    I got a price from an Italian sculptor (10 years ago) for a white marble statue twice the size of those that were in the Colosseum, but it was a very simple/contemporary design - it was $750k.
    Also note that the marble blocks for the Parthenon restoration cost $1.5 million each, for a lump the size of a small car.
    That’s why the Parthenon replica in Tennessee is built from limestone.

    • @sergpie

      Depending on the stone used; the Parthenon employs extremely expensive material like porphyry (nowadays sold as a semiprecious stone), travertine, and marbles from Latin and Campanian quarries that have since been exhausted or close to it. There are also green and blue marbles that are believed to have originated in Africa, whose sources have yet to be rediscovered.

    It is quite curious how the founding of the Colosseum was the only remarkable thing Titus did as Emperor, as the only other things he could do during his reign was trying to repair the massive damage from the eruption of Vesuvius and the Second Great Fire of Rome. Then, he just miserably died of fever shortly after the foundation of the Colosseum, making his disturbed brother Domitian (who also modified it by adding the hypogeum) the first Emperor to actually enjoy the gigantic amphiteatre

When it was finished it probably felt like the Gods would be in attendance themselves. Could you imagine all that white marble shining in the sun and all those thousands of people filling the stands? Eventhough we live in the best (most comfortable) time in history, I often wish to have been born in a time like this.

      Don't put so much emphasis on the sight of some blocks beeing transported. For the people of Rome this was daily business because the whole ancient city centre was build in this way. There was constant construction going on and while the number of blocks required for the Colosseum is remarkable the size of them is not. Marble columns (in on piece) erected for a new temple, giant sculptures moved to the numerous fora/pedestals, the occasional egyptian obelisk, all of that would have attracted a far bigger croud of onlookers than some generic blocks moving through the city in a steady stream over a few years.

    It should be noted that to even get to building the actual Colosseum, a lot and I mean A LOT of pre-building job had to be done. First of all they had to clear the area for building. The area where Colosseum was to be built was actually already occupied by Nero's gigantic Domus Aurea (Golden House). So that monstrosity of a complex that spanned over multiple hills of Rome had to be demolished. Just the cost of demolishing it and then clearing the ruble must've been in millions of sesterces. Worse than that, the exact site where Colosseum was to be built is where Nero built a large indoor lake, which would have to be drained, which would probably be one of the hardest task in overall construction of the arena. Add in multiple smaller work that had to be done, like for example leveling the ground around Colosseum, and just the costs of pre-building would be enormous. Thus it's even harder to accurately measure the then building cost of the Colosseum.

      @@petlahk4119 Oh, it wasn't just because he was rich. The rich were the ones who ordered the construction in the first place, and they DESPISED Nero. They hated him so much that to this day we aren't really sure which stories about him are true and which are outright fabrications, because the Senate and later Emperors' propaganda campaigns demonizing him were so effective that within a few generations everyone in the Empire was convinced that he was like Satan incarnate.
      Personally, I think that Nero was a mostly well-meaning, if short-sighted and and incompetent Emperor. He was at an obvious disadvantage because he was so young, and his overbearing mother basically made all his decisions for him in the early years of his reign. But he had a bit of a god complex (even greater than the healthy amount of god complex most Emperors had) and made impulsive decisions like abolishing all taxes everywhere, and of course beginning construction on a mile-long mansion in the heart of the city. He was the product of several generations of Julio-Claudians being totally removed from the everyday life of the citizens of Rome, and the Senate in particular saw him as a symbol of all the decadence and depravity of the Imperial experiment coming to a head.
      So, yeah. When Nero was assassinated and the Flavians took over, their first priority was damning the name of Nero (both because they actually hated him and as a political maneuver to concrete their own imperium) and wrecking all his stuff, which included the Golden House. Vespasian certainly wanted to create the image of a "populist reform" in planting a new stadium right where the Golden House used to be, but that doesn't mean he really held populist intentions. Like everything Emperors did, it was all about the positive PR.

      There would be nearly no demolition required. You said it yourself: The Colosseum was built at the site of the artificial lake specificially because the site was already cleared (for the lake obviously). The actual buildings of the Domus Aurea are still there underground in the area surrounding the Colosseum. The lake beeing artificial would have made draining it also very easy because they just had to cut off the supply of water and the lake would have drained itself trough the already present outflow very quickly.

    I don't know if you've ever worked in construction, especially with concrete, brick and stone, whatever estimate you come to will never be accurate. Especially on a project this big, projects *ALWAYS* go over budget and almost always over time. That's just how it is. Same people think all contractors are crooks because if this, but in reality, there are always unforseen obstacles and set backs in a project, and the bigger the project, the greater the set backs. Anything from weather, injuries, stolen tools and materials, discovering the ground becomes far more difficult to dig six feet down,broken tools from the very small to very large. Just too many variables, and people tend to estimate optimistically because if the don't, some other company will come in and undercut any realistic bids.

    I suppose one could estimate the land cost in that area of Rome although the value of such a large prime space would likely be well above the cost of small plots. Modern costs from building the Gaudi Cathedral in Barcelona and the Cathedral in NYC on 112th street could be helpful to triangulate estimates.

      Nowadays, (central) Rome has some ridiculous real estate prices for plots/blocks. A building that used to be a ministry office, that’s about 55000 sqft, sold for €104,000,000. There’s a historic apartment building whose mere first floor, courtyard, and adjacent small office buildings are going for about €65,000,000. Rome isn’t cheap in the central portion of the city. Land there has been claimed and built upon for so long that parcels or buildings for sale are sold at an extreme premium.

    Excellent video, as always, I only miss the cost of the project of the engineering team. I guess it must have been a tiny part of the total cost, but today it would certainly inflate the budget a lot.
    Commenting on the video with an architect friend while we have a few beers, he tells me that he would charge 10% of the total project. He has no idea of ​​the rates of 1st century Roman engineers or architects.
    But if you’re really interested in building a replica of the Colosseum, Dr. Ryan, I can invite him over for a couple more beers and I’m sure we can get to 5 or 6% of the total.

    Very interesting topic to ponder over. Speaking as a former quantity surveyor on the contractor side, perhaps a more reliable estimate would have been possible if there were a good set of general building plans along with the structural drawings to enable quantities to be "taken off" (using UK quantity surveying jargon) by a QS. That would allow a common basis for estimates of the total contract sum by contractors and consultants and subsequent tender comparison. If contractors are perhaps worried about any errors in quantities, perhaps the contract could be done on a remeasurement basis that would better allay their fears.
    From my experience, most of the delays and therefore additional cost in a project arise from construction work to do with the ground such poor ground conditions, underground obstructions, hard material, unforeseen utilities, water seepage into the excavation, etc, Once the substructure is completed, unless there are labour shortages and materials shortages, there is really nothing that will further obstruct a main contractor on the superstructure apart from incompetence in project management and foot dragging by the client over variations.
    Further cost and time savings could be had by using Building Information Modelling BIM for planning of the construction process and greater use of precast concrete elements made off-site.
    Talking about the substructure, if the Colosseum is built today using modern techniques, it would be reasonable to assume that it would use diaphragm walls for support for the substructure. That would be a site to behold, a massive excavation held up by diaphragm walls along with a great quantity of temporary works. Great video.

    A look at how much the Luxor Las Vegas project was estimated at, how much it cost, and then the extra cost of refining it gives a good idea of how much use estimates are on large-scale projects.
    A client of ours (we do acoustic engineering and wiring for studios/theatres) had a ~1/10th scale 'Great Pyramid' built as his recording studio and office - steel frame skinned with limestone, granite and various other materials including a (stunning looking) solid naval brass pyramideon.
    It ended up costing almost double the quoted price (before we even got started), and that's using modern techniques.

    This is an interesting back-of-the-envelope estimate, or a Fermi estimate. It might even be surprisingly accurate, because often when people make assumptions, they will overestimate one thing, and underestimate another, and in a happy coincidence these mistakes will often cancel each other out. If the assumptions are anywhere near to being correct, the real cost for building a replica of the Colosseum is almost certainly somewhere within an order of magnitude of one billion dollars. Perhaps something between 3 billion and 300 million, for example.
    That is a wide range, but still very useful in giving us some idea of the scale of the project. It tells us whether building a Colosseum-replica would be an astounding mega-project that only a major country could be able to do, or whether it is something that your average billionaire could build as some sort of personal project, or whether even some relatively wealthy multi-millionaire could afford it on a whim. A price tag of 3 billion max would mean that a major country could easily afford to build one just as easily as any other large stadium, that there are indeed a fair number of multi-billionaires who could probably afford to single-handedly finance the cost of building one, but that it would probably be out of the price range of even a hundred-millionaire.

      Adam Smith said something similar about the relative standard of living of a British working man in the 18th century compared to an African king of his own time. The key to how they felt about it, however, is that both then and two millennia ago the kings had far more power and control and were visibly better off than the labourers. What matters to a lot of people is not how high their standard of living is in absolute terms, but how it compares to everybody else.

    • @californiaplant-basedeater2761
      @californiaplant-basedeater2761 2 роки тому +2

      The whole typical comparing the standard of living argument is always lacking the fact that many working class people (in the US, for example) are often a paycheck or two from being kicked out into the street. That kind of dread and mental weight does not allow one to live better than kings and queens, along with the subjugation of being underlings at various awful workplaces and much more ills of modern day society. A lot of it is overcomeable. A lot is also not... not to the extent that one can be as comfortable as a king with servants. Not that that is necessary to have happiness.

    Thank you for an excellent analytical analysis for what the Colosseum might cost to build today.
    I agree, as you surmised, that some things might be done cheaper due to modern technology while other parts might be more expensive due to higher labor cost.
    But, in order for someone to make the Colosseum today with the modern amenities and internal structure required to pass code, it will likely be much more expensive.
    The most expensive arenas/stadia of today are far more expensive than the high estimate given in your video.
    In fact, there are 10 that have cost at least $1b or more.
    It would be an impressive and monumental task if one should ever decide to build a new Colosseum.
