Donation cost at every level
Alliance tech is funded by members donating earned resources — never money — and the bonus is a pure function of the funded level. Communal Masonry adds +2% to build_speed per level, to +20% at level 10. It applies to every member of the alliance at once, which is what makes a donation to it worth more than the same resources spent at home.

Everything else that moves build speed
Alliance tech is additive with the rest of the game's bonuses, so this tech's +20% at cap is a floor rather than a ceiling. These are the other sources of build_speed recorded in this database:
