The final engineering report is just about done, it will probably go up on Monday. Just wanted to update y’all with the cost numbers. The final design has 368,200 ft^2 of area, and 160,000 ft^2 of footprint (400×400), at a total cost of $95,300,700. This cost includes all structural elements, the hotel, generators, thrusters, fire safety, HVAC, fresh water system, and sewage.
That works out to $258/ft^2 of area, or $600/ft^2 of solar footprint, which is in line with our initial estimates. I had been concerned that the costs might end up being higher – as much as $350-$400/ft^2, so this is reassuring. Also, this is not only less than San Francisco prices, but much of the Bay Area – for example, [current Mountain View prices](http://charts.altosresearch.com/research/CA/MOUNTAIN+VIEW) for single-family homes have a median value of $572/ft^2, [Palo Alto](http://www.altosresearch.com/research/CA/PALO+ALTO) is $819/ft^2, and [San Francisco](http://www.altosresearch.com/research/CA/SAN+FRANCISCO) is $517/ft^2. This is very promising!
We will try to get cost estimates on ships for comparison over the coming months.
UPDATE: Apparently these figures don’t include some assembly and deployment costs. Stay tuned.
