Hi Hanno,<p>The reason I have been reluctant to break down the cost numbers as you requested is that I don’t think they will be very accurate, hence not very useful and even, perhaps, misleading. The reason for this is that we have not bought material according the work phases I have shown on my web site. For example, all the material we bought during the time we were building, let’s say, the south 2nd floor shell was listed as part of the cost of that phase even though we probably had some material left over from a pervious phase and some the new purchases were left over for the next phase. We buy rebar by the ton, not by the phase. Likewise cement in 100 bag lots, sand and gravel by the truck load, etc.<p>The numbers I am posting each week on my web site are intended to give a general idea of costs here VS costs in the US or Canada. The final total might be a little more useful, but it will also be suspect because of the amount of donated labor. The owner guys each donate their days off to work on the project, and later the wives will be painting. So you really do need to be careful in using these numbers to evaluate a bid from a contractor.<p>So with this disclaimer in mind, here is the best cost break down I can reconstruct.<p>Walls: the wall cost is based on the gross wall area; that is, no deduction has been made for door and window openings. This is way the plaster guys price a job. Their reasoning is that door and window openings take a lot of time to get a neat, square trim. Remember these are shell numbers; they do not include plaster or stucco.<p>First floor walls including the foundations: $ 38 pesos/M2
Second floor walls (no foundation): $ 23/M2
Foundations (by subtraction): $15/M2<p>Floor Slabs: I can only give you a unit cost for the second floor. The cost of the first floor slab is buried in the cost of other phases because we poured that slab ourselves in pieces as we had time. The ground floor slab is not nearly as costly as the second floor slab because it has no rebar or plastic blocks.<p>Second floor slab: $ 38/m2<p>Doors and windows are a work in progress, and their numbers would be completely useless to you because Coco (one of the owners) is doing that work himself.<p>Again, I think you should take these numbers with a grain of salt.<p><p>
