I would recommend you divide this section into two parts: Final Design and Construction. Under Final Design include your sketchup and a paragraph about your design, your timeline, and budget table. Under Construction include all the steps you took to begin construction along with your picture galleries.
UPDATE...You won't be including individual costs for each material that goes into the blocks you will use (that's block biz's job) instead I assume we will estimate cost per block and reference the other block team's budget/page
Fix math - if total $US was what you were aiming for (which is helpful) then make sure you label it as such and also add a total RD$ column
Add introduction (explain that this is only for the foundation) and seriously consider adding an estimate for completion
